My new hot air/soldering station is... so much better than the soldering iron i used to have

quartz wren
#

Oh no doubt and I plan to upgrade but my point is even good work can be done with crappy tools

static flare
#

it was only $90AUD, and it's both a hot air gun and a soldering iron, and it heats up so much quicker

quartz wren
#

I may need to.... Reshuffle my finances again and lean more heavily on currently held assets to get my game console going so I can invest in that

#

What's the model?

#

And is it available in the US?

static flare
#

it's a 8786D clone

quartz wren
#

I have nothing against clones... If the price is right

#

(and for small scale individual use, I'm pretty against it for mass scale purchasing but I digress)

dusty citrus
quartz wren
#

No my first language is 'Murrican

#

I'm a native speaker of American English I just play with my words before eating them

dusty citrus
#

yeah the sentencing structure seemed sorta French that's why I asked

#

I'm not sure yet about soldering iron and lab power supply...

quartz wren
dusty citrus
#

insurance company says they need to be UL/CE certified and made in the US to cover damage if they cause it...

#

Had a tektronix soldering station in mind that cost 100$ or a hakko one that costs 350$ (they have UL/CE and not made up one/fake ones from corruption money from china...)

lusty fossil
#

There's being a dork, and then there's taking pride that Digikey Chat Support agents always pass you off to an applications support tech.

dusty citrus
#

There's also a pen one I could use meanwhile

quartz wren
#

¯\_(ツ)_/¯

#

Not saying don't trust the real ones or that you should trust the fake ones, but the argument about corruption money is simply moot

#

The argument should be one of whether the cost you save by not getting a real certification is worth the lack of real certification

dusty citrus
#

Nah I mean like in China I saw many documentaries from DW / France2 etc where everyone seem to print fradulent labels like made in italy or CE/UL and the law doesn't care

quartz wren
#

It is generally not

dusty citrus
#

And when I see a 5$ charger from china and look at what is inside and it doesn't have even basic safety feature that tell me human life isn't value in such products

#

so I can't trust anything that is inherently dangerous from there like a soldering iron or power supply

quartz wren
dusty citrus
#

and even there are tests that says the design pass basic safety guidelines like UL and CE

#

and I've had a corsair HX 750 with electronic components from Japan for almost 15 years

quartz wren
#

So people say "oh why am I paying more for this one than this one with the same labels?" as an unaware consumer and end up making a market for it

dusty citrus
#

vs the no-name cheap one that advertising 750W but the components inside wouldn't go past 350W and broke in 1 or 2 years

#

so far that power supply cost me 9$ per year... vs 40$ a year for the "cheap ones"

#

so I had my lesson

quartz wren
#

Let's say I'm aware it's a terrible idea to buy power supplies from Chinese companies

#

I bought a supposedly 1KW PSU for my PC for cheap and it was uh

#

Not a good decision

dusty citrus
#

I mean you do what you want, not trying to influence anybody, just saying for me and for what the insurance company says and I have a small apartment and lots of tenants in the building so it doesn't work

#

I'd rather do what the insurance company says in the long run

#

and if a power supply last 1 millenia that's what I want 🤣

quartz wren
#

First off the fan bearing died in a month, kept resetting the system any time I pushed the GPU, ended up damaging the motherboard chipset as a result of undervolt during reset rather than a full disconnect and reconnect of the supply, etc.

dusty citrus
#

yeah gpu dying in a year was a common symptom of these PSU

quartz wren
#

But it was either that or a computer that didn't meet most of my needs

dusty citrus
#

or not powering the computer on at all when you added a a cd drive... even if it was far off the supposedly 750W

quartz wren
#

And I wasn't aware of the potential for problems at the time

dusty citrus
#

And I kinda see a power supply like a bike lock

#

You don't buy a 300$ bike lock to protect a 500$ bike neither do you use a 50$ bike lock to protect a 8000$ bike...

quartz wren
#

I had $600 to work with to make a computer that could do GPU rendering in blender <2.8 (before my GPU wasn't supported anymore and I was sad)

#

Already had the GPU so the rest was a scratch build

static flare
#

it's a clone in the same way my lab bench power supply is a clone

dusty citrus
#

and I mean this isn't even about us/china/whatever it's more having real/verifiable certs that I can show my insurance company if something happens

#

Like "I did my job now pay up my claim"

quartz wren
#

Gotcha, I realize we were kind of talking from slightly different contexts, I was just saying that the reason a market exists at all for false certs is that the general consumer public aren't made aware enough of the importance

dusty citrus
#

Yeah I know that too, I've had the power supply argument before with peoples IRL and they didn't know until they invested in a good one

#

And didn't understand the "naive person" who spent 150$ for one (me)

#

And I mean even for me, the hardest one to buy with cert is a lab bench power supply if I ever need one

#

certified ones costs a fortune

quartz wren
#

After my incident with the PC supply I decided if I'm going to have a cheaply produced supply I'm going to learn to build it cheaply myself but verify the quality myself

#

Not for PC but for bench supply

dusty citrus
#

basic ones with mid-range volts/ampere from b&k starts at 400 US$...

#

When I bought for PC power supply there was a guy testing them with high-end gear

#

and the main thing in them besides the components being rated at what it claims is ripple/noise

#

something that need a lot of bandwidth to check and is into the realm of DSP, not really something an hobbyist can afford to do

quartz wren
#

Not something a hobbyist who's buying hobby gear at hobby prices with hobby timescales and time budget and at hobby knowledge levels can afford to do. 😉

dusty citrus
#

depends on the project

#

An e-bike starts at 3000$ where I am

#

If that is ever something I want to do and the total project cost is 800$ but I need a 800$ power supply or oscilloscope to do it correctly

#

I still save money

quartz wren
#

Yes but if you are dedicated you can build each component from raw material using 3D printed jigs for coil winding and such

#

And it's about a third of the price or less

#

But yeah if you're a standard hobbyist the limiting factor is actually time

#

I'm not a standard hobbyist

#

I have all the time in the world

#

So much so that I can make barely any money stretch across many projects

dusty citrus
#

yeah that's why when I show up at my fablab and they have 12 machines for construction work

#

and learning each take 2-3 months I get discouraged

quartz wren
#

(out of necessity in my case until I can manage to get self started)

#

I've been working with 3D printers for some 5 or 6 years now

#

I can level any printer I've come across just using my eyes

#

No leveling card

#

And it gives me better results than using a card

#

But I added automatic leveling to my printers just because like... Tedium

#

(yes, fully automated)

dusty citrus
#

I don't even know what a leveling card is

#

I just hope that before I did my time metal 3d printers are widely available for 500$ and you can order a furniture to print it rather than wait for it

#

etc

#

atm I'm very interested in experimenting in joysticks whatever the cost

#

plus maybe one day I can reuse it to drive an ESC on an r/c or an e-bike 😄

#

I really wish I had a tractor like dashboard with a new holland style sidewinder HOTAS for gaming...

#

good news is they apparently can be used on a microcontroller

late fulcrum
quartz wren
# late fulcrum Hmm, 3D printed coil forms, that's a good idea

Well yeah, 3D printing has two main advantages over other manufacturing methods: if you keep within some fairly forgiving constraints they can manufacture shapes that are simply impossible using other methods, and you can iterate on things quickly

#

Turns out 3D printing is best put to use in a lot of cases as shape references rather than the actual object itself

late fulcrum
#

I agree. I'm tempted to try lost PLA casting.

quartz wren
#

I'm going to be helping my brother cast my old engine block into stuff with that method

#

(aluminum block)

late fulcrum
#

Excellent

#

The battery tray in one of my appliances broke, so I just 3D printed another one.

quartz wren
#

Another excellent use of 3D printing

#

OH!

#

my ruby nozzles arrived today

#

😄

late fulcrum
#

Nice! Those are good for abrasive filament

quartz wren
#

Not that I can make use of them right now since the tool steel ones work for the glow filament I have

late fulcrum
#

Heh, I haven't tried my glow filament yet, but I do have a steel nozzle I plan to use with it.

quartz wren
#

I mean I'm going to install them but I need to also install my 500C thermocouples and get some carbon fiber infused polycarbonate filament to fully put it through its paces

#

And glass infused nylon

late fulcrum
#

Those are some serious composites

quartz wren
#

Also got full self leveling on my printers

#

Have to tune stuff once I get the nozzles swapped but both proved that they work well enough to print

#

And the prints are gorgeous when I have it properly tuned in

#

With no user leveling option even available

#

Next step is to get a high temp heat break that a bowden tube won't degrade in, make a custom shelf with just enough operational space for all the printers I have planned, and run Teflon tubes to each printer spot from a common filament dry box

#

I still have to figure out whether I want my small printer to do 3 materials or my big one

#

I have a diamond head nozzle that can mix 3 plastics through the same output if configured correctly

#

And if I add another separate nozzle I can do a CMYK printer

#

I wish I'd saved for a 5 input nozzle though

late fulcrum
#

I ended up going with a titanium heatbreak, it seems to be working well

quartz wren
#

So I could do CMYKW

quartz wren
#

Actually... Shoot... What's a 5 input diamond head cost rn

late fulcrum
#

I have no idea

quartz wren
#

Oof

#

It's hard to find now because there's actual diamond tipped nozzles that dominated the SEO

late fulcrum
#

Heh, that's what I thought you meant

quartz wren
#

Did some research after finding them

#

Turns out 5 colors doesn't work very well

#

At least with that design

#

I need to design and have my own machined

#

To address the issues I've been reading about

#

Mostly it's heat management issues

#

And color purges

#

And mixing

#

Actually

#

If I use virtual foundries' metal infused filament

#

To print a nozzle

#

.....

#

I could totally have a printer print it's own new nozzle

#

Because the mixing chamber needs to be designed after a mixing tip on an industrial adhesive applicator

#

Which is hard to do with traditional metal machining

#

Otherwise you'll have the striped toothpaste effect I've been reading about

#

I may spring for some brass infused PLA to print my own printer nozzles (which is then sintered into a slightly smaller solid metal part)

#

Yo dawg I heard you like printer nozzles so I'm printing a printer nozzle with a printer nozzle

honest moth
#

BOOOYAH!!!

#

CPU TEMPS HAVE REACHED AN ALL-TIME LOW, WITHOUT a significant impact to performance!

#

#

YEEEEEEEEEHAAAAAAAWWW!!!

#

late fulcrum
#

Or BSD

#

cool concept and cool all around, no doubting that

#

but just not for me.

late fulcrum
#

Fair

quartz wren
#

I may be able to make a desktop SLS printer using a repurposed DVD writer assembly...

#

Keep it on its gantry, set that on a second gantry, remake the control circuitry, and add the powder bed system and you've got a tiny high precision selective laser sintering setup

#

Not sure if it could melt metal but if it can its built in gantry is big enough to 3D print 3D printer mix nozzles for FDM with baffles in the melt pot to properly mix the plastics

#

Could even do a helical baffle....

#

Heck with SLS I could do baffles of literally any physically realizable shape

#

I have a literal pile of DVD drives just hanging out on a shelf

#

Will get laser goggles before I play with it

#

I think I actually figured out a super simple solution to the mixing problem

#

Just a helix that twists a couple of times and reduces in size from the melt pot entry point to the nozzle exit

#

Basically a >45° from horizontal helical surface or series of baffles that forces the plastic to complete at least two twists before exiting

#

That way even if it isn't thoroughly mixed you at least get it mixed enough to trick the eye as well as pixels do

#

(that is, beyond a certain distance depending on the quality of mixing)

quartz wren
#

Oh yeah the lab also got a smoke detector yesterday

#

Yeah so today I got bored on my English classes and made this

Imagine boredom in English class being the exception and not the rule

#

I am making an esoteric programming language in English

#

Unfortunately this sentence can be modified by removing "English" and it makes no difference.

orchid zephyr
#

Yes

quartz wren
#

This is why I teach myself whatever I want to learn in the comfort of my own home using the internet

#

Well not my own home but within my own space

#

And now I have my own lab 🎉

#

Turns out building a lab is a lot of work even just at 120 square feet

#

But I have it now

#

I'm going to revolutionize self education if I can

burnt tendon
#

I dono, I've had some great English teachers when I was younger. We just don't give people who teach enough respect.

#

One of them made fun of English majors as people who studied the heck out of Shakespeare yet never wrote a single bit that was anywhere near as good.

#

Also, I have glass-fiber nylon and carbon-fiber nylon and I have yet to crack them open and try them out.

quartz wren
#

And there's a good argument to be made that it's because the incentive structure in the education system itself is to blame

burnt tendon
#

Yeah, some of the best teachers on the college levels were the non-tenure-track lecturers.

quartz wren
#

My best English professor ever was a total hippie and told me exactly how things go behind the scenes and effectively talked me out of continuing formal education because I do better outside of it

#

I didn't follow through on the advice I was given until two quarters later when it just became all too clear he was right

#

I'm pretty sure I only passed that class because I was willing to go to the professor with my concerns and he fudged things because he understood my perspective

#

I'm great at formulating arguments, I just don't like the idea that something is only valid if it's a properly formatted argument.

#

And I "suffer" from a combination of ODD and bipolar

#

In reality everyone else suffers from it but I'm the one who has them

#

The ODD makes it effectively impossible to conform for conformity's sake. If the reasoning to do something doesn't make sense to me then I'll do something that does. Period.

#

And because of the bipolar, during the high periods I get interested in things and I'm conforming to satisfy the interest, then the low point hits and I can't even make myself do stuff I want to do but I've got obligations that I made while I was in a high state that require me to conform just to do something I now don't even want to do during a period where I can't make myself do most things even if I want to

#

It's a struggle and it's impossible for me to fit into either the education or employment structures that currently exist so I'm making something that can accommodate what I deal with, having margin for differences, because I know there are others similar to me though the likelihood of someone needing exactly the same accommodations is nil so it needs to be flexible

#

If you want the basic concept of what I'm shooting for, it's a charitable design, prototyping, and inventing firm. I don't need more than what will allow me to survive, though I have the skills to make plenty if I could manage to conform to certain systems just long enough... But I'm eligible for disability (and several people over the years including two therapists independent of one another have been telling me that it makes sense to leverage in my position) so I'll use that to survive and then design open source inventions that I think humanity needs

#

Anyone know much about pipe fittings? This is a 1/2" pipe and flange, can't seem to twist it past where you see. Might be because my carpal tunnel is real bad today and I can't grip anything. I'd unthread it an examine the hole/threads but...carpal tunnel.

Thoughts?

quartz wren
#

Do you have a pipe wrench?

lusty fossil
#

Maybe

quartz wren
#

If so you can put screws through two opposing holes into something well anchored, then turn the pipe against that using the wrench for leverage

lusty fossil
#

I wasn't worried about getting it out so much, but thanks. I work with non disabled people. But should it go further is the main question i should have posed.

quartz wren
#

Oh if you're mounting it on a wall or floor you want the pipe to be flush with the flange base

#

Otherwise it'll damage the surface as it's attached

lusty fossil
#

I want the flange to be further down the threading

#

As far down as possible

quartz wren
#

Then you'll need a relief hole for whatever length of pipe goes past the flange base

#

In the surface you're attaching it to

lusty fossil
#

We are miscommunicating, I'm just trying to get the flange down the pipe right now. I know how I'm going to attach it to the surface it's for. I'm wondering if what I'm trying to do is impossible

quartz wren
#

Oh on pipe fittings they're tapered iirc

lusty fossil
#

It seems like it is

#

Hm ok

#

I'll have to figure something else out

quartz wren
#

Yeah as you put it on further the clearance gets tighter

#

So that you can seal for fluids if I'm remembering the explanation I got about this years ago

lusty fossil
#

Yeah that sounds familiar

orchid zephyr
#

i would screw it off and then tap the threads in the flange

#

like retap them

#

if you have a tap that wide

quartz wren
#

Actually that'll do it

lusty fossil
#

Most of what I learned about pipes in school wasn't practical

quartz wren
#

You just need the flange to make a tight seal at the wide side of the taper

lusty fossil
#

I was considering that, i don't, but depending on cost it might work

#

I'm actually not using this for fluids at all

#

So I don't care about seals

quartz wren
orchid zephyr
#

if you dont care about it that much you could grind it down and weld i guess

lusty fossil
#

Removability is useful

orchid zephyr
#

ah

#

what is this for?

lusty fossil
#

A thing for work, he says mysteriously. Everyone who'd know about pipe fittings is off doing things

orchid zephyr
#

wait did your boss tell you to do that?

lusty fossil
#

It's more my interpretation of a general desire she expressed.

orchid zephyr
#

lol

lusty fossil
#

Thats how it works around here

orchid zephyr
#

use wd 40

#

its always the solution

lusty fossil
#

I don't think even WD 40 can handle mechanical interference on this scale

orchid zephyr
#

use wd 41 lol

lusty fossil
#

A tap is 10.50 at home despot, I think I'll try that first

orchid zephyr
#

#

Make sure to oil the heck out of it,when taps get stuck it’s a massive pain to resolve

I find that knowing a variety of computer languages helps me enormously in picking up hew ones. I can get a read-only feel for most new languages in seconds to minutes, can be modifying programs in less than a day, and writing new code in about a day (although expert code usually takes a bit longer). Of course, this is accumulated skill from about 60 languages learned over half a century.

tardy badger
#

true, I can use most any language with enough time to review it's basics or look at what someone else is doing

wooden schooner
#

Unreasonable macros defined in the Arduino library?

#

I was shocked that the Arduino lib defines min and max as macros that output a ternary expression, so that min(expensive_thing1(), expensive_thing2()) evaluates three expensive expressions not two

#

Min and max are in no way specific to arduino, and this seems like yet another attempt to force the compiler to inline things when in reality the compiler probably knows better - and in this case the macro version had a big obvious downside

#

Ok, rant over... I had that one saved up.

my cheap handheld one is coming today with the probes (the main reason I wanted it)

My current scope is fine, but it needs new probes and they'd have to be calibrated and it's a whole thing where I'd prefer to just get a scope that has a support process

That's the important part

I also want something with modern features

#

I thought calibration was something you have to do with any new probe, regardless of the oscilloscope

I think you're right, I mostly want one with probes that aren't from a random bin and were meant for the machine and also with neat features/functions

an analogue one (which i have) for XY mode, and for general waveform analysis, and a digital one more for the snapshot stuff and the like

Im going to have some fun soon. My phone is integrated with home assistant and has very many sensors including sleep confidence and next alarm. My laptop has 21 sensors although some of the sensors are useless to me. I am going to try to see what I can come up with different time/sensor triggered automations using my data from my laptop/phone. I use sleep confidence to turn all my stuff off if it thinks im sleeping

#

Also a big thing is I can track, view and analyze my habits across my phone and laptop which is why I like home assistant so much, it's easy and all of my data is under my control because I would not want anyone else to have access to it. It is very useful to me in many ways.

Update I had two screws that match in the box that I have to pay homage for the stuff I disassembled for no good reason

#

Weird luck

#

If you put weight on one side of the rest more than the other, it places torsion on the screw, obvious design flaw

#

I’ll make a cross brace for it

#

I have shop class tomorrow actually

#

Nice

# stray wind That's so great to hear!

Yeah, it helped me get past my technical interview and onto the “let’s continue the conversation email” it’ll be full circle when I have an offer 🙂

It’s great that all the work I’ve done with I2C and SPI made it so that I could confidently talk about and talk about how I would implement solutions to situations

I see, my local shop use standard big screws so I bought the most solid (young modulus etc) I could find and didn't even bother with their and just used my screws over 3 chains already 😄

If it was possible I would have gotten titanium screws

Is this kind of fuzzy trace typical when you're approaching the edge of the scope's frequency range? This is 0.5us per div, on a 20mhz scope. Or is this just the kind of thing you get from a 35 year old piece of equipment? Lol. I can't figure out how to slow down the signal to check. Being generated on an esp32 so could it be an artifact of an 8-bit DAC? (Also a 10x zoom)

dusty citrus
#

I'd say the top one show 4 enemy aircraft

late fulcrum
#

That looks like the wave is varying somewhat, you can try adjusting the sweep frequency, trigger level, and trigger holdoff to freeze a more stable subset of the wave. The scope appears to be working nicely.

#

That looks a whole lot like mains interference, your connection to the signal source may not be properly referenced.

brisk spire
#

This is my first scope so It's all very new to me and ive got lots of questions... what is the sweep frequency doing? is that "SWP VAR"? It seems to stretch out the wave horizontally but im not sure if that's it or it just appears to be it. Near the center of the knob, I see a single wave, but towards either end I see two waves just about out of phase.
What is trigger holdoff? I dont seem to have that knob unless it's called something else. I've been playing with all of em but I can't seem to get a clean wave, other than reducing the time/div. Or, when I touch signal clip, it gets cleaner..

brisk spire
late fulcrum
#

There should be a click-stop knob to set the sweep frequency in steps, and a variable control to adjust it between steps

#

That scope may not have trigger holdoff (a feature on some fancy scopes)

#

With that hookup, I would fully expect hum pickup like that.

brisk spire
#

Switched to a frequency generator kit that I built a while back, much much cleaner signal

I recently replaced my HDMI audio extractor (HDMI input --> HDMI video-only output + S/PDIF or RCA audio) with a newer model. The old one works perfectly fine, but supports HDCP only up to version 1.4, so it can't play some DRM-protected content, particularly from Disney's streaming service.

Is there any good use I can put the old device to, including giving it away to someone who has a use for it?

Anyone good at painting? I'm bad at scale. If a person's head is 12 in wide at the widest, how would I figure out how far apart their eyes should be to not look weird?

No, I'm not doing the drawing. I just need the information about a single figure. It's not drawn yet, or I'd just measure, so I'm hoping there's a rule of thumb I can use.

Will have it in a couple of day was 18$. Electronics box from dubious brands were 40-120$...

#

colors aren't the best but that can be fixed by sticking carbon sheets and rpi/arduino stickers 😄

#

also got 0.6mm solder lead in this package and that led/magnifying glass plastic "helmet" thing

#

going to go donate my printer to staples as well soon even if it still "works" take up some space

#

time to do some spring cleaning and maybe get some space for a peg board with a solder station... because my community electronics lab won't be able to solve that problem

late fulcrum
#

I use tackle/craft boxes too, and the creative storage units offered by the Plano Molding Company and so forth.

dusty citrus
#

Would be that for me for around 2400 US$

#

not just for electronics storage of course, I have bicycle tools too

#

And that 1000$ workstation table (except with steel top) for vise, to mount dremels or saw etc (950 US$)

#

the organizer would be right to the right of the L shaped workstation table (door facing leftwards

#

If I had a windfall like the 2nd prize in lottery I'd rent a commercial space that would be around 700 sf for this hobby 🙂

#

In my city a low-scale CNC/PCB business would probably works because this sort of thing isn't mainstream in my city and the companies that does it locally won't do anything unless it's a least for half a million (they are industrial scale for an order of say 10000 parts)

#

also it's better than buying a big house and making a workshop because you pay 3$/sf a year for common spaces/services among which is one where you they clean and you can throw the sawdust/pcb shrapnels/sodler etc in an industrial bin and it's disposed of properly. Also a loading bay for semi doing deliveries (which enable freight delivery) and the option for 3-phase 440V/600A outlets

dusty citrus
#

Prefered to not put a company name/link unless someone asked

lusty fossil
#

Is this the packaging company?

dusty citrus
#

yeah the uline packaging companny but they sell a lot of stuff to business as well. I always liked the soap/tissue dispensers they have in office so I bought one for home

#

But generally they are expensive and downright scammy (like the cleaning refills that are 1/4 of the price ion hardware stores) and the huge shipping costs, and not really a place for delivery to home (they ship most of their stuff by freight trucks which require a garage door, garage elevator and spaces for semis)

lusty fossil
#

Hmm, well, I'll have to see if I'm willing to order from them for my job. I avoid them in my personal life.

#

I am getting a work space and it needs a desk

dusty citrus
#

Yeah I heard their owners were controversial. They probably have competitors, would just like a simple catalog if I had the opportunity to have a business where I know what is being sold has decent quality

#

Without having to "request a quote" every single time...

#

Really like that hakko soldering bot too, too bad it costs between 20k$ and 80k$ depending on options 😄

#

Staples/hardware store are nice for entry-level stuff but not much more unfortunately imho

#

and they seldom list weight limits as well

#

If I bought a worktable for a business I need to know that I can put a 1 ton machine on it and still keep me and potential employees safe

dusty citrus
#

When I look for partition it only shows floor versions, not one you'd put on a desk to better organize it or so that move than one person can work on the same table

#

something like that but higher, not called a sneeze guard and opaque

#

that way I could partition my L-shaped desk into personal computer | shelves - workshop -shelves | office remoting computer

I made a 50cm/2m/1m (d/w/h) workbench out of aluminum extrusion and it ran me ~700 after all was said and done. Hardware ended up being way more expensive than I guessed

dusty citrus
arctic folio
#

Even with that footnote I think that's pretty fair

#

Heres how my thing ended up

#

I actually really dig the alu extrusion for this- easy to take apart if I want to move it, lightweight, and I can bolt on stuff like power strips no problem

dusty citrus
#

you made that on your own?!

arctic folio
#

Ya

#

It's just t-slot aluminum extrusion
Super easy to work with

#

Like everything but the wood is off the shelf parts

dusty citrus
#

I'm not very manual and have no tools but trying to find a way to organize my desk better/partition it/hide gaps

#

I mostly have lot of cardboard from moving boxes

arctic folio
#

If I was to approach partitioning I think I wouldn't bother with tall panels

#

But instead just like, bars across the desk clamped to it

arctic folio
#

So that whole thing could just be assembled with a screwdriver lol

#

2x4" wood segments are also off the shelf too and that makes a pretty nice top

dusty citrus
#

basically have a loft and trying to fill the gap between desk and counter with the slope and partition off the counter

#

no idea where to start beside covering/cutting theses boxes and gluing some metal looking sheet to them (maybe aluminium foil)

#

the partition on the counter would have an hole for the fan power cord and hole for my charger so I can hold my phone on it

#

but there is a 6-7 inches gap above it

#

dust keep getting in these caps and I have to constantly broom these hard to access places which make me enjoy life less

arctic folio
#

Aluminum foil will rip the second you look at it funny

#

With minimal tooling I think what I would do is just clamp a plank to the desk
Won't be flush (or look great) but it will be sturdy

dusty citrus
#

yeah and abs/acrylic seem to be hard to find in opaque colors at under 25$ per sf

#

don't like the texture of wood but can be easily be changed by gluing some sheet to it like a roll of carbon texture

#

and yeah the boxes have to stay there, not only it prevent dust from getting under, but it save storage space in my loft that is only 620sf

#

my counter is stone though, can't really drill into it, and I'd rather not drill in the desk. I can support a piece of wood with the boxes

#

but for the counter it's harder, I'd probably have to hammer a piece of wood in so it stand on it's own

arctic folio
#

I wonder about adhesive strips

#

Those 3m command strips or whatever might be able to support something nicely

dusty citrus
#

like the ones for picture hanging with velcro ?

arctic folio
#

Yeah lmao

#

Not the Velcro ones sepcifically

dusty citrus
#

so just to know but did you use something like a dremel 4000 rotary tool to cut the cast aluminum ?

arctic folio
#

No a table saw lol

#

Also it's extruded not cast

#

With less tools I would use a hacksaw

#

Aluminum is nice and soft do you want to cut it more than grind it away like you would with an abrasive wheel

#

(with no tooling at all, you can order whatever lengths you want)

#

They'll even drill and tap the ends for you so you can do blind joints

dusty citrus
#

I have no idea where to order extruded aluminum though and it would probably be much more pricey than wood/abs/acrylic right ?

arctic folio
#

Misumi ec

#

1m of 3030 is uh

#

Somewhere between 11-17$

#

I forget where

#

Total bill for all the metal there was ~250$ iirc?

#

If I was doing it again I wouldn't use the corner plates which added a huge sum to the cost

#

But instead use blind joints and corner gussets

dusty citrus
#

trying to find a panel I could cut on their site

arctic folio
#

Also- home Depot and friends can usually cut wood to lengths

#

I used to buy plastics from Read Plastics, about an hour's drive from here, but they closed their doors. I found some other services, but they wanted me to buy full sheets and tell them how to cut them and send me the pieces.

Tax season has passed but I’m still dealing with the bologna caused by working in one state initially and my employer not paying taxes for that state..

So they just assume that I was in Utah for the whole year

Like, literally, the worst. I would like to meet the person that has ever gotten a return on their NC taxes. I took a sabbatical for an entire year and still owed them taxes, somehow. Like, what? 😄

#

I think the most I got in the past was $300

But somehow 2 months worth of income accrued $1800 in income taxes

Barely $17000 in taxable income

Wow. I have never gotten a return from NC. Federal, I think the biggest I ever got was some $7,000 or something when I still claimed my kids back in the day.

#

That's whack, though. They must have messed up something with residency or whatever.

tardy badger
#

To be fair I was in school and sustaining on food stamps.

#

No the taxes part was on my employers part. I sent them North Carolina tax forms, they even listed NC Resident for state taxes in my pay statements but paid $0 in NC taxes, paid them all the Utah, even when I didn’t live in Utah

#

Anyway, taxes are stupid

#

The way they are done anyway

fading hare
#

Yeah. Taxes are stupid. We were owed taxes, like, quite a bit. Fed decides to claim that we never filed for 2016-2018. Which we did, just not online. Then they audit us, which took them a year and a half... Guess what, they somehow figured out that we owed them $4k, somehow. Some guy in an IRS basement was probably like, "there, I fixed it!"

I did need it a few days ago, however. When I completely mangled the metadata on the 10 TB btrfs partition that was on that NAS. I missed the point where btrfs is a "technology preview" in Proxmox.

#

(it was in RAID 10)

#

I was able to extract the data, however.

#

But, the metadata was toast. I could find absolutely no way to restore it. 😦

dusty citrus
#

lol chirality 🤣

#

the only chirality I know of is in chemistry so this is funny to me

quartz wren
#

I mean technically parity also fits but it's more ambiguous

#

Chirality is just the rotation direction relative to the direction of motion

#

(or the direction of rotation relative to the direction the bit sticking out is pointing in the chemistry context)

#

It also applies to circularly polarized light

#

Because the overall circular progression can go clockwise or counter clockwise along the direction of motion

dusty citrus
#

also doing spring cleaning and I'm sick of my broom and mop falling down

#

and want to install a peg board even if it mean plugging the holess when I leave the apartment...

quartz wren
#

What about individual clips with sticky backing?

#

Then the worst you have to do is repaint spots where it peels on removal

#

Alternatively you could get a setup that's like a larger version of a tree for a set of wood stove tools

dusty citrus
#

not sure the sticky stuff like 3m command brand strips would work well if the pegboard has some heavy stuff on it like dremel, box of nails/screws etc

quartz wren
#

Basically just 3 clips on a vertical pole with a weighted base

#

For making sure they don't fall over but can be tucked into a corner

#

Doesn't cover the tools like the dremel but the cleaning tools would be taken care of

dusty citrus
#

oof drill bits are much more complicated than I thought. Reading the home depot tutorial

I've been using power tools since I was in single digits of age

#

So I may be able to help

dusty citrus
#

Well I'd rather have a set with different types of bits for the variety of work I want to do. Driving screws in stuff, fastening/removing hex bolts specially on a bicycle (pic to follow), making hole in something that doesn't have a mounting kit to screw it in a wall, making up to 2 inches diameter holes in hard wood up to 0.5" deep(hole saw/spade bits) which may have varying width accross the depth (fortsner/countersink/step drill(???))

dusty citrus

#

Ahhhh okay I normally use hand tools on a bike

dusty citrus
#

This is the hex bolt tool that I'll need to impact drive if the freewheel still refuse to come off

#

it's the adapter for a shimano freewheel and there is a smaller hex inside

quartz wren
#

Have you tried using a cheater bar and a mallet?

dusty citrus
#

cheater bar yeah but an old pvc pipe, the workshop I'm renting for 2$ an hour monday probably have a steel/brass one

#

and they have bench vises which is how I removed the difficult ones in the past

quartz wren
#

Yeah pvc tends to break pretty easily when used as a cheater bar 😅

#

Depending on how old it'll either shatter or fold at the apex

dusty citrus
#

I'm not sure how to tell by the picture, maybe you can

#

but in the spec it says drill/impact driver

#

product name says RIDGID R70011 Heavy-Duty 8 Amp 3/8 in. Corded Drill/Driver

quartz wren
#

Looks like a Jacobs chuck which says to me it's a dual mode unit but I also don't see a torque selector which tells me it isn't

#

So I'm confused

dusty citrus
#

trying to find the manual to see how to switch mode

#

manufacturer website also says VSR drill/impact driver

quartz wren
#

Often there will be a dial behind the chuck that has different torque settings with the highest marked as a drill bit but the dual mode impact / drill units ice seen have the same type of dial but with a hammer sitting past the drill bit

#

Hmm

#

I wonder if it uses the distance you push the trigger to determine mode

#

Either way if it says it's an impact as well as a drill it probably is

#

Because false advertising gets a hefty fine

#

(note: only really applies across the board to medium-large domestic corporations)

dusty citrus
#

"The direction of bit rotation is reversible and is controlled by a selector located above the switch trigger"

#

don't see anything about switching between drill and impact in the manual

quartz wren
#

Yeah that's standard on many drills and impacts

dusty citrus
#

doesn't even say impact in the manual

quartz wren
#

Hmmm

dusty citrus
#

"The drill has a keyless chuck that makes it simple to tighten or release drill bits in the chuck jaws"

quartz wren
#

Also pretty standard on battery powered drills

#

Dedicated impact units have a quick release similar to air hoses

#

Hence the recessed region on the hex shaft of the bit

#

There's a ball in a detent with a locking system that pushes it into that recessed region to prevent the hammering action from loosening your bit

#

(on a Jacobs chuck with a hammer action it's a potential failure mode)

dusty citrus
#

Seem to be a combo in the same tool, doesn't actually say drill/IMPACT driver, only drill/driver

quartz wren
#

Okay that makes it sound like its not actually a proper impact mechanism

#

Impact bits can be put into a Jacobs chuck but not the other way around

dusty citrus
#

but from what I read impact dfriving are for driving a lot of fasteners, while for me it would be a minor use ?

#

And if else fail i'll just hammer the screw in the wall and untighten / retighten it manually ?

quartz wren
#

If you don't do a lot of metal fasteners a regular drill will do pretty much everything

#

And if you get impact bits they'll work in it still

#

You just don't get the hammer action

#

If you work in the shop a lot the best bet is to get both

#

For driving screws I much prefer using an impact but for drilling holes it isn't great even if you can find the bit you want for it

dusty citrus
#

nah it's for home use, the fablabs I'll use will probably have both

#

2nd one has a dedicaterd wood workshop but it costs 6$ a day to rent and the annual membership is much more expensive

fading hare
dusty citrus
#

they are also going to have a metal machining shop/smelter/forge soon

quartz wren
#

And I've only tried it with wood

#

And I only have an impact

dusty citrus
#

considering getting a dremel 4000 eventually as well, but not sure it's of any use if one doesn't have a manual stand

fading hare
fading hare
dusty citrus
#

impact driver of the same brand are all cordless and twice as expensive so it's clearly not a real impact driver

quartz wren
#

And I think those actually were Stanley brand

fading hare
#

that's not going to work well with an impact, for sure

dusty citrus
#

so an impact driver is the power version of a manual punch then ?

fading hare
#

spade bits and circular mcguffins are something you bring out your big [insert pronoun] drill for.

dusty citrus
#

and auger bits, not that i'm ever going to drill soils or concrete

quartz wren
dusty citrus
#

I see, what about impact driver vs impact wrench ? They are completely different too ?

fading hare
quartz wren
#

Speaking of impact drivers...

#

I have to install my fume hood

dusty citrus
#

are there manual tools that kinda help if an hex bolt is stuck ? is that what socket wrench/ratchets do ?

fading hare
#

Actually, I misspoke. My bits are all DeWalt. Forgot I upgraded them.

quartz wren
#

You want that thing to be able to be serviced mid ride

fading hare
#

My impact driver is the 20V MAX

quartz wren
#

So only hand tightening

fading hare
#

(Remember, it's not a lubricant, it's the exact opposite!)

quartz wren
#

Just remember that any place you put WD-40 that should be lubed needs to be re-lubed before you use it

dusty citrus
#

eh I always forget about wd-40, non-destructive destruction 😄

fading hare
#

I've heard of some guys with opinions like using it on their firearms, but no, don't use WD-40 on anything you wish to keep lubricated.

quartz wren
#

after cleaning the WD-40 off

fading hare
#

EXACTAMUNDO

dusty citrus
#

well since I'm switching my wheel I need to move the freewheel, which mean i'll have the grease the new wheel

#

not much more of an effort to also grease the whole thing and the sprocket

fading hare
#

yup, so WD-40 will be great in that use-case

quartz wren
#

So WD-40 to service, carburetor cleaner to remove the WD-40, then machine oil

dusty citrus
#

but I'd be surprised if the bench vise won't work

fading hare
#

(wear protective gloves)

dusty citrus
#

these things have so much grip and I'll be turning the wheel clockwise ...

#

not much better manual torque than this

#

speaking of which, only safety glass I can get atm is 3m securefit and not the 4$ one-use disposable ones

#

But I don't understand how these can even fit ? Doesn't seem to be adjustable for various sizes of heads ?

quartz wren
#

Completely off topic to this off topic conversation but I decided I'm going to make a super low power go-kart using one of these with a weed whacker engine

#

Going to change the license plate from "CZY COUP" to "CRZY COUP"

dusty citrus
#

I guess that would be the other choice at 6x the price, pretty sure using a full-size circular saw in a 620sf apartment is illegal though 🤣

#

Also I wish I was go enough at DIY construction to do stuff like that, I'm really starting from zero never had tools etc

quartz wren
dusty citrus
#

never used a cnc or 3d printer or laser tool or even vinyl machine

quartz wren
#

He got the full Dewalt set though

#

The one that comes in a straight up suitcase

dusty citrus
#

problem with cordless is that they lack power so you have to check voltage and if it's brushless or brushed that's why I want with corded as well

#

I imagine it takes a lot of motor to dig a 2 inch hole with an hole saw in a thick hardwood piece

quartz wren
#

For my personal lab

#

Currently I just have printing

dusty citrus
#

20$ a year fablab has 3 of them in in desktop, entry level and mid-level

#

including a rare one that was great bang for the price that is out of production and lot of peoples still want

#

All I have to do is follow some training and help others to use it, seems like a good deal vs what they cost

#

anyway give me sec to find the datasheet so I can ask the most important thing for the drill

#

I'm not sure "2 inches diameter holes in hard wood up to 0.5" deep(hole saw/spade bits) which may have varying width accross the depth (fortsner/countersink/step drill(???))" properly conveyed what I hope to do

#

I'd like to make a pc joystick that use a keyswitch from a real tractor, these plans seems to suggest I have to drill 3 holes of specific depths and specific diameters across the same hole in a wood panel for panel mounting

#

Seems like I have to make a 0.61" diameter hole that is .39" deep and then a another one that is 0.75" and 0.19" deep to hold it with the nut to hold it securely?

#

google seems to say I have to use a spade flush mount drill bit for something like this

quartz wren
gusty pilot
dusty citrus
#

let me highlight it

#

I found some fibre washers in the basement (the previous owner had a vast collection of fasteners in jars down there, left some behind).

They work really well securing an artist's easel (beechwood) without crushing or denting the wood.

#

then just the wing nut supplied by the easel manufacturer (they give you flat brass washers).

dusty citrus
#

when I move I'll look for a more workshop friendly apartment and less sensitive fire fighting equipment

quartz wren
gusty pilot
# dusty citrus

yeah, drill the hole for the biggest part, where threads are just to the left of your rectangle

dusty citrus
#

Hope hardwood will be enough for the torque this can do. Will probably need to stick the end result to my desk too to prevent it from moving

#

But I really want a key, never ever seen one on a joystick

gusty pilot
quartz wren
#

Everything I own exists inside those 8 walls

#

And it works for me

#

¯\_(ツ)_/¯

dusty citrus
#

I mean the hallway is literally created by the space between my furniture, couldn't be more cramped

quartz wren
#

Used to just run my 3D printers and other experiments in my bedroom but I had an incident with chlorine gas poisoning due to being silly about electrolyte choice in an electrochemistry experiment and decided I absolutely needed a separate lab space with a fume hood and talked to the land owners and the result is a building mostly made from scrap materials to do lab work in

dusty citrus
#

I have a big L-desk in here and a big table, only space I have for a workshop is my L-shaped desk

#

but vertically, hence the peg boards

#

and adding wood panels so I can reclaim dead spaces in gaps

quartz wren
#

Just barely got moved into the space a couple weeks ago

dusty citrus
#

hence the drill 😄

quartz wren
#

Reusing dead space is the theme of this lab when it's fully set up

#

Think tiny home but a lab

dusty citrus
quartz wren
#

Very nice

dusty citrus
#

showing that pîc earlier but I'm hoping to replace these with plastic/wood panels

quartz wren
#

Ahhh

dusty citrus
#

so I can divide my tight space and get more bins/shelves in that deep space. Also the box over the desk prevent dust from getting in the gap

#

And make me an happier person as I don't have to constantly broom it now...

#

tomorrow I'm getting scrap presswood at cost from the hardware store so hopefully I can hammer a plank on the counter behind the fan

quartz wren
#

Well I'm not exactly in design mode at the moment due to being (hopefully toward the end) in a bipolar down swing however my brain can't help but to answer specific questions it has the answers to in any state I'm in

dusty citrus
#

so that it will stay sstuck without needing support

#

I'll still use that cardboard behind the computer screen though as it make the wall less boring

quartz wren
#

And if you put up paintings

#

It makes the walls less boring

dusty citrus
#

I don't like the texture of cardboard or wood, so I'd glue on some metallic paper like the one in the picture

quartz wren
#

I'm going to paint murals as I get things set up in my lab space

#

Try to make it feel like the walls aren't a hard boundary and trick my brain into feeling like the space is bigger

dusty citrus
#

wall height mirrors are great for that 😄

quartz wren
#

Ooh good point

#

But at the same time I'd want them not to be glass

#

Because I have a history of clumsy

dusty citrus
#

and they are expensive, and sometimes the glue the installers use have manufacturing issue and a mirror fall off

quartz wren
#

I mean

dusty citrus
#

happened to me and chipped my toilet

quartz wren
#

Have you seen the pic of what I did to my keyboard?

dusty citrus
#

I mean I have to change keyboard every year since I'm a dirty llama

#

that's why I have all those spare keyboards boxes and I always buy the same one

quartz wren
dusty citrus
#

It's like a yearly rental

quartz wren
#

Guess that outline

fading hare
#

maybe not solder right next to the keyboard?

quartz wren
real falcon
#

each year? man my keyboard is umm 13? 15? years old lol

quartz wren
#

This was before I had the lab set up

orchid zephyr
dusty citrus
#

my 2020 keyboard corpse 😦

quartz wren
dusty citrus
#

Not even worth trying to clean unless I had a very powerful vacuum machine with automotive scale brush

#

Like I said yearly rental 😄

#

Anyway the keyboard letters and mouse paint start to fade after a year

quartz wren
dusty citrus
#

so for 40$ a year it's perfect 🤣

#

air duster or air compressor ? duster just make it more sticky

quartz wren
#

Oh... Do you eat junk food at your keeb?

#

I may solder next to mine but that's keyboard abuse

orchid zephyr
dusty citrus
#

That and I'm dusty anyway pieces of my body get in and I can't help it

quartz wren
dusty citrus
#

My current keyboard is the 2021 rental and still alive

quartz wren
#

Discord sent me to the wrong message when I clicked to view what it was replying to

#

So I thought you were saying the keyboard pic

dusty citrus
#

But I'm a bit more careful with it until letters fade again

#

I also have a tons of surplus alcohol wipes due to my covid anxiety attacks

#

2021 keyboard

quartz wren
#

I can't stand the feeling of bits of stuff between my fingers and my keyboard

#

So I wipe my hands before typing

dusty citrus
#

I also have a spare that is used for my xbox/raspberry pi 2+

quartz wren
#

And if I eat at the computer I finish a bout of nomming, wipe up, use the computer, then stop using the computer for the next bout

#

But that's just my personal sensory stimulus thing, I don't like stuff feeling weird when I touch it

dusty citrus
#

I don't eat much chips but I like making french canapés (so crackers...)

#

What may help now is my big desk

quartz wren
#

See, what causes rapid buildup is typing with the bits still on your fingers and leaning over the keyboard while eating

#

(I know both from experience)

dusty citrus
#

which have enough space for a plate and the keyboard above it

quartz wren
#

Used to be pretty messy at my computer and it just got to me one day and I couldn't do it anymore

#

Now it's just like... Resistors and hair I contend with

dusty citrus
#

Did I mention in that dead space because there is a difference of elevation I'm going to make it 6 inch high and install 3 automotive cupholders in it ?

#

Just so I have cup holders next to my counter ?

quartz wren
#

I mean that's a solid way to have things less spillage inclined near sensitive things

dusty citrus
#

And the divider on the counter will have an holder for two smarthphone so I can use my old one as a door viewerhole camera and recharge both

quartz wren
#

I may have to print some cup holders to mount to my desk

#

Good idea

dusty citrus
#

with an hole drilled in to pass the wires for the desk fan and the two holders

#

Just need to find a heat-proof enclosure for my arduino stove sensor and I'm good for the counter

quartz wren
#

Dang you're just full of great ideas... I was trying to figure out what to use for the camera in the peep hole for my lab but now I have a phone that isn't my main phone

#

And it has a decent camera

#

And I also wasn't sure what to do with that

dusty citrus
#

I changed my old phone because the camera is broken but at close range it's ok

quartz wren
#

My old phone fell on its screen on a rock on concrete

dusty citrus
#

My front door is very secure and thick so sometimes I don't even hear peoples knock which is the need for that camera

quartz wren
#

Decided to upgrade but I had to get a bricked one to repair the old one to recover my 2FA

#

So now I have an extra phone

dusty citrus
#

Also I have an auditive problem that cause me to hear loud bangs/explosions sometimes when I'm tired that are illusions so this make me feel safer that someone isn't trying to force their way in

quartz wren
#

I'm familiar with auditory hallucinations. I have schizoaffective features with my bipolar

dusty citrus
#

I already use command strips to hold stuff on my desk or on the wall near my entry door so I don't lose them

quartz wren
#

So I often hear a whole bunch of random people (some I know, some I don't) whispering my name barely audibly

#

Among other things

dusty citrus
#

like my air conditioning remote is stuck to the wall with a sticky velcro pad so I always know where it is

quartz wren
#

But it's all in my head

dusty citrus
#

right under the unit

#

I don't hear random peoples in that way but I kinda know the feeling because sometimes I'm so tired I fall asleep on twitch

#

and I get woken up by loud streamers after a couple of raids in the middle of the night, sometimes in a foreign language

quartz wren
#

Yeah it's super strange because

#

I'll hear my name

#

Turn to look in the direction

#

And there's nobody there

#

Then I hear someone else say my name and I turn to look and again it's nobody

#

By now I've learned to identify when it's happening by that point

#

But even once I've identified that it's happening I still hear it

#

But growing up with 10 siblings many of whom liked to mess with me by whispering my name and pretending nothing happened didn't help

dusty citrus
#

Yeah for my loud bang thing/explosion sound I learned to check if someone around me is alarmed, first time it happened I called 911 because I thought they were gunshots or something

quartz wren
#

See I hear gunshots on the regular where I live

#

And explosions

#

(live out in the county so things are a bit more lax)

dusty citrus
#

mounting for using an old phone as door camera

quartz wren
#

So even if I were imagining some of it, I would have no way to know

dusty citrus
#

I just have to press the protective case of the phone and it hold, eventually I might run a power cord extension to it stapled to the wall and the charger to keep it permanently charged. But atm I charge it manually and only put it there when expecting a delivery or at night

quartz wren
#

But also thinking about that... It's super odd the number of explosions I hear nowhere near the 4th of July or new years with how close I live to an airport

#

Coming from the direction of the airport half the time too

#

I know a while back some extremists were attacking trains nearby

dusty citrus
#

I live 2 streets from the police station which mean no drone even if I legally could under 250g

#

So if the noises I hear were real they'd hear it too

quartz wren
#

I can't fly anything above like 50 feet iirc

#

I'm within 5 miles of an airport

dusty citrus
#

me too, but since it's under 250g there is very little regulation since it's considered a toy

quartz wren
#

(without a commercial drone license and getting clearance from the airport for every flight iirc)

#

Yeah the only drone I have worth flying outside has a 7' wingspan

#

And so I just can't use it

#

Right now it's disassembled

dusty citrus
#

The only rules are restricted airspaces (so nothing around 1.8 nautical miles of the airport, around jails, military bases etc) and not putting peoples in danger while flying it(vague law so they can apply it if you are really annoying)

#

That's why I don't want to fly it near a police station I'm sure they'd find a vague obscure law

quartz wren
#

Yeah I'm right at the edge of that 1.8 nautical mile bubble

dusty citrus
#

Kinda need a car if you have a drone in canada because you can't really fly it anywhere near a city unless you are a license pilot for real planes

#

when you are a real pilot you can ask for NOTAM to fly near the airport even if it's a drone and you don't need drone licenses

quartz wren
#

Used to be 5 miles as the crow flies when I was first trying to figure out where to fly the thing long before the FAA came down with registration requirements

dusty citrus
#

FAA has notam as well anyway and real pilots could always fly drone even in restricted airspaces

#

since they can with bigger planes 😄

quartz wren
#

I'm not a real pilot

#

Too broke

#

And broken

#

¯\_(ツ)_/¯

dusty citrus
#

I mean with the price of graphics cards and how hardcore flying sim joysticks have become

#

It's almost less expensive to pass a VFR pilot license 🤣

quartz wren
#

I'm not saying I couldn't become a real pilot

#

Just that I wouldn't be allowed

#

I've been doing flight simulators since I was like 12

dusty citrus
#

I took an introductory flight before but nothing more serious

#

the 1st hour is basic theory so you can save your instructor life if needed so they take it seriously

quartz wren
#

I'm considering setting up a multi monitor battle station with a full blown cockpit button panel and stick for playing KSP

dusty citrus
#

Didn't have the courage to try to land because I always crashed while landing in flight simulator

#

Also took a lot of fitness because you have to keep hitting pedals on the cessna to keep things straight

quartz wren
#

Landing takes a lot of practice even in simulations

#

But apparently it's something I learned pretty well

#

One time when I was visiting Kennedy space center with my family my dad tried the shuttle landing simulator and crashed like 5 times and I asked for a turn and nailed it on the first try

dusty citrus
#

they had me do a level flight and an easy turn and practice "flight management" a bit by roleplaying my instructor as the tower and checking maps while flying
