[quartz wren]

Yeah USB 3 ports definitely going on the list

[weary fiber]

hella USB, everything else on an IO shield is legacy or mostly unused

USB C is fun for front IO if you've got a fast portable drive that goes above USB 3 speeds

but USB C on the rear.... seems kinda useless? at least for now

[quartz wren]

I can make a whole row of USB C headers on the front edge so that you can choose where / how many you want

Since that edge isn't being used anyway

Personally I want to have at least audio ports and a serial port just because I'm into the legacy stuff haha

[weary fiber]

actually yeah, def have a USB type E port somewhere-- they're not super commonly used, but it's a pain in the butt if you have a need for it

[quartz wren]

As well as vga because I need it for my console

Actually screw it. I'm going to just leave that space unpopulated, release the design files, and anyone can modify it with the ports they want...

The real important part is the form factor and the prototyping grid

Might even make a tool to just choose your ports and have it populate automatically

Just have standard customized part layouts for how they connect to the grid so they can be arranged however you want

[thick wind]

Have you ever considered starting a blog? I've lurked through your stuff for a while now and you have more than enough content haha

[quartz wren]

I have a hard time with blogging because it lacks engagement in my experience

[thick wind]

I see. Maybe streaming then kek

[quartz wren]

I mean I have an urbit group I dump all this stuff to as well, it's just nice to have spaces I can throw ideas and get near immediate input on them.

[thick wind]

Ahhhhhh, gotcha.

If you have space for ports without functionality, maybe just setup some debug pins. Dual row headers, male or female, are pretty easy to add extra function to.

[quartz wren]

Well in the base design all ports will just be broken out to a prototyping grid

That way you can implement them however you see fit

So everything will have debug pins by default

It's so annoying when I watch a TV series and then suddenly they change the brazillian voice actor...

It happened with Kirk in Star Trek and now with Amy Santiago in Blooklyn 99 at this new season 7.

It's sad because you get used to the voice in the actor, but then they change it.

Do you believe physics are a function of time?

That reality is just a point

Is anything truly unpredictable

[slim shard]

cause and effect tend to require time, so kinda, yeah

unpredictability is a function of not knowing or being able to process the details needed to predict

No clue just got started with it myself

I'm designing a SMD board too

Well, combo SMD / through hole prototyping board conforming to mini ITX form factor

Will accommodate at least one BQFP package plus a bunch of smaller ones

(so I can put a 386SX on it)

(but the actual design is one where I will be able to do all sorts of configurations)

Initial prototype of my game console (named Pixie) will be implemented on it using a Pico, then eventually I will be able to put the RP2040 straight onto the board when I have the thing fully figured out

[quartz wren]

Coffee is morning

[dusty citrus]

IIRC the Apollo 11 had parity memory which shows how radiation in space can affect memory even as low-density as ferrite core memory

[crystal ore]

It might have had more to do with the signal-to-noise of the memory readout circuitry. I don't think radiation could flip a bit of that size.

[quartz wren]

Yeah you'd need some pretty high energy particles to flip the magnetic state of a ferrite ring...

Also what kind of solar magnetic flux would they be experiencing?

Because at that distance it would matter more than earth's magnetic field but I can't imagine it would be that much higher in strength

@late fulcrum the voltage converter is here.

😄

It's so cuuuuuute!

YES IT CAME WITH BOTH A REGULAR AND 90 DEGREE HEADER!

So I can make it lay flat on the board and slide in sideways so it isn't rattling

[delicate stream]

noice

[quartz wren]

Not opening that until I'm ready to use it

Too small to find out here if I drop it...

So now that I have the integral piece I can start designing the battery module

But brain r not gud 2dai

But I figured out Proto-ITX

Mostly

Putting the SMD prototyping space opposite the interfaces so you can run buffers and stuff or just jump it through from the SMD space

Oh

Oh my

Okay

So you know how I was saying I can interleave two 0.1" pitch grids with each other to compactify SMD breakout?

I can do the same in the through hole prototyping space but the holes that sit between another set will have connections going the opposite way across the board

That way you don't have all the grid connected to itself both ways but it's really easy to jump to a bus running the opposite way

So you can do jumpers that don't look ugly

So basically imagine you have a set of holes spaced at 0.1" on each axis, then connected along one axis. Standard strip board. Then you take that grid, flip it to the opposite side of the board, rotate 90 degrees, and offset it to the spaces between the holes

This also happens to line up pretty well with that Japanese through hole standard that's skinnier pitch

If you rotate it by 45 degrees

(the kind you see in a lot of Japanese analog equipment like VGA monitors)

It lines up okay with the 0.1" pitch at 45 degrees if you bend the pins in alternating directions along the rows

But with something like strip board it's hard to isolate each pin from one another... Not if I have 2 interleaved and opposite direction grids of strip board...

But then there's the whole gap to isolate both rows from one another... Know what? In that space that isn't breaking out pins from an SMD pad I'll just have either no connections between the grid or pairs of holes and still make it so that each square grid is running perpendicular to one another

Whichever lines up better for the most number of configurations with as little effort increase as possible

Goal being to never have to cut traces but have to solder fewer

If I just make it an open grid I can make it much more flexible at the expense of quite a bit more work

Might be worth it though

Since then I don't have to worry about removing any traces when I convert it to the final version, just adding the ones I've defined on the prototype

Just design it clean and easy to follow, using that same philosophy of all points that are in the same grid are parallel and all points between grids are at 45 degrees. Then I can just drop the traces in as defined by how they are on the board into kicad for the final design and leave the rest of the space for modding by users

Or rather not even keep the grids separate.... Just have it so all wires on one side of the board run one way and all on the other side run the other way... Kind of like how a lot of retro computers were designed

But have that whole double interleaved grid to accommodate more chips and more pitches

Anyway it's getting much closer to reality

Pretty sure I know exactly how to design all the pads I need and so far nothing seems to be standing in the way of Proto-ITX's existence but me

Anyway I'll do what I can tonight and get the battery module set onto a board

[quartz wren]

Decided to mount the module vertically so that it can more easily accommodate a heat sink if necessary

And rather than plugging it into the board, it has a header that another bundle of wires can just connect to in parallel to the board it's on

Soldered to this board so I can solder a heat sink to the board and not have it fall off

Then has a header that something else can plug into it from externally and get its output as well

That way an external board can power this one, and get its power stabilized by this one, and I'll add a header for RGB charge color codes from the nano

And the enable / disable signal

[waxen wasp]

Well that was the best movie I've watched in quite a while, thank you for bringing it up!

[slim shard]

what is a good price per watt on solar panels? (smells like about $4 on bezos's platform, low score is now $3.33)

[quartz wren]

The battery control board so far

Decided status board will be separate and will request status via this... Then I can just have the nano do battery monitoring instead of the super granular battery level indicator from the charge control chip... Just let it do monitoring to keep the battery safe

[quartz wren]

Probably just going to have the battery module separate and deliver power via USB

As well as battery status over serial

[dusk oracle]

ok so i recently tested another idea.
where i share a 64MB of ddr2 with the fpga, sd controller and esp32.

[late fulcrum]

[dusty citrus]

Helium lasers 🤔

Was making a keyboard matrix until I ran out of GPIO, looks like I would have to lay it out the hard way (11x11 instead of 18x8)

[late fulcrum]

The red, orange, yellow, and one green dot are from helium-neon lasers. The other green dot and the blue and purple ones are from an argon ion laser. Sadly, the helium-cadmium laser you can see in the background isn't providing an additional dot.

[dusty citrus]

By putting all 109 keys into a 11x10 matrix, I can save 5 pins for the status LEDs so I would not need an I2C IO extender.

[delicate stream]

https://tenor.com/view/stevenuniverse-star-gif-4782048

[quartz wren]

Gonna need to look into this for expanding Pixie

[quartz wren]

Shift registers?

[thick wind]

Looks more like rearranging of matrix. 11x11 makes for some funky wiring...

Not sure if people use shift registers for keyboards?

[quartz wren]

They could

Ben Heck made a video on it

Use it to sequence the input to the matrix then read the outputs

Then if you put that on the larger side of your matrix you can use fewer IO pins

For reading out the smaller side

And when you get a bit on the output of the shift then you know a scan cycle has completed, you can use that to trigger an interrupt on the MCU as well as feed it back into the shift register at the beginning of the chain

So with an 18x8 you can use 5 4 bit shift registers and instead of the normal shift out use the first unused bit on the last shift register for feed back or just add another 2 columns to the matrix

And then you only need 8 IO lines to read in the data

And one for triggering a scan cycle

Plus a clock

So 10 total

Then once you trigger a scan, you buffer in each byte of data until the interrupt signal is active that denotes end of scan

In this way you can make an arbitrary width matrix with only those 10 IO lines.

(assuming a height of 8)

So really the formula for finding the amount of IO you need for this schema is height+2

Since the width is arbitrarily selected using only 2 lines

You could do an arbitrary size matrix on both axes but the readout is a bit more complicated

[delicate stream]

They were pretty common on USB Typewriter projects back in the earlier days of Arduino

[spice moss]

https://www.spacex.com/launches/ Inspiration4 mission stream started by the way

[dusty citrus]

I am trying to keep latency to a minimum by having no ICs between the MCU and the keyswitches so I went with the 11x11 matrix option instead.

[quartz wren]

I mean if you're scanning one column at a time from the MCU there will be the same latency as pulsing a shift register to shift a single bit across the columns

Since you're activating each column sequentially regardless

Just uses fewer pins

[dusty citrus]

hmm, yeah

also helps with BOM and circuit complexity

[quartz wren]

I'm just trying to offer suggestions, please don't feel any obligation to follow them, won't upset me one bit how someone decides to implement something but if I can be helpful it feels good

[dusty citrus]

I did not mean it that way, thank you

I start looking at something I want to do and halfway through prep I'm already moving on...

Did manage to get groceries shopped.

[dusty citrus]

Most of the day was at school, now out in the lab seeing what I can do with a Pi 4B

[quartz wren]

I wish I could do school how it's structured... I enjoy the social aspect and I enjoy the learning but I can't learn in a classroom at someone else's pace

Always learn more from the other students than I ever could from the instructors

And about things I actually want to know.

Rather than budget padding filler curriculum that gives you nothing of value

[dusty citrus]

Tech center is the only thing that actually teaches me something that I need to use. Other than Java class and chemistry ofc.

[quartz wren]

I was in engineering club on my last attempt to do school... That was fun

Learned more in one month there than all the prior quarters in classes combined

With no accreditation

So worth nothing to those who think a diploma means something.

All it means is you convinced a system you learned things you may not have.

Holy crap. Degrees are like the Turing test. It can fool a lot of people but it does not necessarily equate to learning...

Or even thinking.

[dusty citrus]

Engineering class has no "college credits" with it so does nothing towards the diploma

[quartz wren]

Yes I know

[dusty citrus]

Diploma means nothing to me but having a little more of a chance to be accpeted into something

[quartz wren]

My point was it's the place where I learned the most actual useful stuff.

[dusty citrus]

yes

[quartz wren]

I'm not trading my sanity or my life for a chance at a piece of paper that still barely increases chances.

And yes, both are the price I would pay to continue trying.

Or there's the choice of keeping both at the expense of a soul.

For the record I'm still happy today, just can be both happy and express my vehement dislike for something simultaneously

[quartz wren]

huh, turns out microwaves with like a bunch of indicator lights that use a 7 segment panel have just an overlay on a bunch of generic LED rectangles

just pulled off the mask for the indicators and this looks like something I can definitely use

I'm thinking I may even just have this be the readout for battery status onboard the battery module

which will not be integrated into the laptop, just plug in through USB and serve data requests about the battery pack over that USB port's serial terminal

so it'll be a client device that provides power

and serves information about the power

that way I can just plug the laptop in without the battery pack and not have it take up precious space inside the case, but still have the option of a battery pack

basically just a smart battery bank that can serve data requests about its status and maybe even receive control commands for some stuff

idk point is, I'm thinking I'll have this onboard since there are 14 indicator lights around the perimeter plus the ability to show the battery percentage down to the precision of the readout

which as it happens is somewhere between 0.1 and 0.2%

problem is, with how my battery packs are, they're going to look like a straight up bomb until I have a case on them

currently one is a bundle of 9 cells in a triangle, but I think I want to add 6 more cells and make it a hexagon

erm

no 6 cells

6 cells it has, 6 I shall add for a total of 12

in a nice little hexagon

all in parallel so I don't have to worry about balancing since I have a boost converter that I have confirmed working

although for some reason it doesn't want to charge my phone from it

but it runs other stuff just fine

and I checked that output polarity was fine and threw a cap across the output voltage (which is definitely working because it takes some time for the light on the Nano to die out)

and the Nano runs just fine even with a nearly dead battery powering the boost converter

oh also I found something out today

if you have a completely non-functional lithium cell that has completely discharged and you disassemble it, you can find material inside that will work for making your own home made electrolytic capacitors (the permeable membrane part)

so a completely dead lithium cell can be repurposed into apocalypse caps

but not the money kind

[late fulcrum]

Most of the microwaves I see have a vacuum fluorescent display. However, I have a couple hundred LED displays with digits and some different colored annunciators, not sure what I'm going to do with them.

[jovial path]

I am thinking in buying a yellow black Star Trek shirt, like O'Brien.

[quartz wren]

Just took apart one of those cheap projectors that passes a bright LED through an LCD panel and then on through some optics

Started as a salvage mission because I was sure the optics were cracked somewhere (line across the image)

But when I got in there it was just a hair

So it turned into a repair operation and I learned how to shorten its focal distance to be more useful

Definitely going to add this to my laptop

It's almost the exact height I wanted to make the base

First I'll see if I can shorten the focal distance even further. I want it to focus on a sheet of A4

So I can throw up a notebook and have another screen

(or rather, about that size)

Will also drastically increase brightness because as you shorten that focal distance the inverse square law works in your favor

It will suffer a bit from abberation but I think I can fix that by making a straight optics chamber for it instead of one with a 45 degree bend. Also would fit better into the laptop that way

Erm 45 degree mirror, 90 degree bend

Anyway good news is I now have a projector to play with

Oh and it has a CPU on board

Just need to reverse the code and write my own for it...

Then I can do some crazy things like using the projector's CPU as a coprocessor while the projector isn't running or doing graphics processing for the output from it

Oh snap

I see silk screen marked "TX", "RX", and "GND" right next to each other. I smell serial.

Haha

It's right next to a flash chip

And they're marked as test pads as well, so I'd bet that's the in circuit programming ports for the firmware

Could also be the flash with the UI image data

And I'm not 100% but I think the CPU is ARM based... Gotta remove the board again to check

Oh that's a dedicated LCD controller... Hope it has off-board memory for programming if it uses an MCU to drive it :/

Well... This is annoying

I can find places to (ostensibly) buy these chips but I can't find any sites with a datasheet

Part number TSUMV56RBUT-Z1 if anyone could manage to help me out a touch I may just be missing something obvious

If this is just for panel control then there's another chip on here I have to find

[delicate stream]

So I ripped open a camera and shoved an amber LED near the sensor and now PWM gives me glitchy effects... Left some debris on the sensor to make it feel like an old tube cam

This is the dumb I do with $3 webcams

[quartz wren]

Heh

[delicate stream]

I only killed 3 LEDs in the process XD

I need to be careful, I only have like 970 left :P

[quartz wren]

Oh snap this thing has a dedicated mmc chip

Yeah all signs point to the CPU being in the chip I can find for purchase but can't find the datasheet for...

Huh, it's just doing the SD stuff using a USB to SD chip lol

So they could have put another USB port on this thing and just shipped it with a USB adapter

But I suspect they did it because it's the cheaper option to enable SD out of the box

This is my mother's favorite fruit.

I like it a lot to eat like this and also in juices.

it's tradictional here to make a desert with this fruit.

[late fulcrum]

Since it grows in your part of the world, that makes sense. Unfortunately, it's difficult to ship, so it's uncommon in a large chunk of the globe.

Crab is delicious, so is crawfish

[delicate stream]

Haven't had crawfish, but I'd try it

[subtle fable]

One of my favorite things to order from the restaurant i work at is a crawfish po’ boy

[quartz wren]

they're really easy to catch

bacon on a rope

[tardy badger]

Me: gets item from Aliexpress or amazon
Those stores: “tell us about your experience!”

[quartz wren]

Question is, which is your favorite? Crawfish, Crayfish, or Crawdad

jk they're all names for exactly the same animal

[subtle fable]

I was about to say

[quartz wren]

I know where to get them locally all you need is bacon tied into rope and a colander

and of course

a fishing license

[subtle fable]

All fun and games till they pinch you

[quartz wren]

meh, they're little guys

I get worse injuries slipping with a screwdriver

[tardy badger]

See that’s the cheating way of catching them

Rocky Mountain crawfish are the most fun to catch

Go up to a crystal clear mountain lake and catch them by hand

Lol

[dusty citrus]

or just lift a finger, cast an eye, and say "Waiter?"

[tardy badger]

Lol

[delicate stream]

Crayfish best name

[dusty citrus]

Yeah we say cray-fish like the computer

[delicate stream]

I want a Cray supercomputer

[dusty citrus]

craw - nope - crawdad - you're watching a movie about the South

[delicate stream]

Craww-dayd

[dusty citrus]

yeah craw-daddy I think I've heard in tv/film maybe

[delicate stream]

Craww-dayud...

[dusty citrus]

I seem to recall that we had them in Connecticut streams.

[delicate stream]

I don't think they're common up here, at least not in my area

[dusty citrus]

Cambarus bartoni bartoni (Fabricus) Common Crayfish

Cambarus robustus Girard Big Water Crayfish

At least those two are in Connecticut.

Shellfish make me think robots

[dusty citrus]

Pretty sure they're rather related to those 7-year cicada type bugs

[spice moss]

from palladium i think of stark arc reactor

[dusty citrus]

https://en.wikipedia.org/wiki/Arthropod

both Arthropods ;)

I thought that was more specific - just means 'insects (including cicadas) and crayfish are related if you go far back enough'

I thought it meant like with food allergies ;)

[delicate stream]

EVERYTHING is related if you go back far enough :0

[dusty citrus]

Right but I thought there was a link between shellfish allergies and something to do with specific families of bugs ;)

Just curious if anyone here that is into music plugins/vst/synths and such is taking part/aware of IK Multimedia's 25th anniversary Group Buy? They are up to 15 free software products when you buy 1. Max of 25. Idk for me this is huge because I have been eyeing their plugins for a long while so I bought Amplitube to start (I love my guitar heheh) and have since redeemed about 13 so far and am going to have some fun with adafruit and midi and these plugins for sure. That's the goal anyways.

[wooden schooner]

Does replacing an ordinary light switch with a slide dimmer switch ever require touching something other than the replaced switch itself? Is the wiring in a residential building ever somehow configured in a way that doesn't allow dimming?

or, is there something about typical hardwire light fixtures that doesn't allow dimming even if a dimmable bulb is inserted?

[jovial path]

I finished a Forest session.

[dusty citrus]

Finally got the Xeon laptop out on the bench. Better than using a TV box chip for circuit design.

[delicate stream]

So long as the bulb/light itself is dimmable, only the switch needs to be replaced. Some dimmable LED bulbs require a specific type of dimmer

[wooden schooner]

cool, thanks. Does that answer change if the house was built a long time ago?

[delicate stream]

So long as you're not, like, on knob and tube wiring, nope

[wooden schooner]

nice.

I still feel like I should insist that my friend hire an electrician rather than try to do it himself

is that a correctly calibrated safety assessment?

[delicate stream]

Can't hurt to hire a pro! A pro will have a voltage detector to tell if the line is live [just in case, say, you turn off the breaker, but it was marked wrong]

[quartz wren]

It's all color coded and marked where the colors go so long as you're buying standardised things

I'm doing the wiring in my lab. Can't afford to hire an electrician and I know enough to do it correctly

[dusty citrus]

Did the wiring in my lab a month ago, added a subfeed panel too. Server rack even has its own breaker.

[quartz wren]

Nice

[stray wind]

My housemate just replaced a light switch with a special one that requires a key so we could use Hue lights in that room without accidentally turning them completely off and making them uncontrollable. As Doctor said, pro can't hurt, but it's definitely DIY'able.

[wooden schooner]

wait I want to know about this switch!

for my own place 🙂

[quartz wren]

Yeah that sounds sick

[wooden schooner]

regarding DIY'able, my model is that it's DIYable with high probability and a small to moderate chance of dying

[stray wind]

They're pretty great. I have Hue dimmer switches in all the rooms with those key switches so I can still control the lights from a switch, but they're always left on so I can control them from anywhere I can control Hue.

[quartz wren]

That chance diminishes with experience and awareness

[wooden schooner]

yep, this friend has no experience

[quartz wren]

Then probably best to hire a pro

[wooden schooner]

best way is probably to hire a pro and shadow them

[stray wind]

I think this is what we have: https://www.amazon.com/Leviton-1201-2IL-Locking-Single-Pole-Grounding/dp/B0039PPMHO/ref=sr_1_7

[wooden schooner]

I've found that pros often oblige when customers are curious. For example asking baristas about the mechanics of steamed milk

[quartz wren]

This is kind of how I'm doing my lab except I'm doing the work and having my dad who has wired up a bunch of buildings shadow me and check my work

Not a pro, but experienced

[stray wind]

Those switches are a better option than removing the switch entirely and wiring the lights to be "on" inside the wall. Which I have done in the past 😄

[wooden schooner]

@stray wind sorry to be slow here but, what's special about that switch?

[stray wind]

It requires a key to turn it on and off. So I can't accidentally turn the power off to the lights when leaving the room. So I can still control all my Hue lights from my phone or a Hue switch.

If they don't have power, you can't control them with Hue.

[wooden schooner]

what is a Hue switch?

[stray wind]

Ah!

[wooden schooner]

I thought Hue required wifi

[stray wind]

They do!

[wooden schooner]

oh then it's still on my poo list

[stray wind]

But, they have dimmer switches that you can add to your setup.

That also require the Hue Bridge and so on.

As far as I know.

I don't think you can use them standalone.

[quartz wren]

So the switch with the key is to prevent the wifi controller from losing power?

[stray wind]

No, to prevent me from turning power off to the light fixtures in a given room.

[quartz wren]

Ahhhh okay

[wooden schooner]

slow again: what is a "key"?

like the thing you stick in a door?

[quartz wren]

I'm going to guess a cylindrical wafer lock

[stray wind]

Yep! It looks weirder than a regular key, but essentially that's what it is.

[quartz wren]

Oh so an actual lock nifty

[stray wind]

It's a flat piece of metal with a little prong on the end that you put in that switch I linked to toggle it on or off.

[wooden schooner]

is that essentially the same as putting tape on the lower part of the switch so people doesn't accidentally turn it off?

[stray wind]

It's not a unique key or anything.

Yes!!!

[wooden schooner]

oh I guess you can still actually turn it off if you truly want

[stray wind]

I did that until we added the key switch. The tape, I mean 😄

[quartz wren]

Oh I actually saw something for doing this using barrel jacks and plugs

In a really old electronics tinkering book

[wooden schooner]

what I would love is: a hue controllable, dimmable, high max output (1600-2000 lumen) bulb

with an E26 base so I can screw it into a normal lamp

[quartz wren]

I think it used a latching relay and used a switch on the barrel plug to allow you to switch it while plugged in but it would hold state if no input changes

[wooden schooner]

that does not do WiFi IoT, just a normal light switch please. Something that I can put on the wall and not expose it to the internet.

[quartz wren]

Which meant you could plug it in, flip the switch, and unplug it so it can't be switched

[wooden schooner]

I have not been able to meet even N-1 of the above requirements so far

I currently switch out bulbs in my lamp at dawn/dusk, between a high-output 5000K bulb and a high-output 2700 or 3000K bulb

[quartz wren]

Oh no I remember now it used a toggle latch to hold state so it would only switch on a full cycle of off/on again

[stray wind]

Oi. My Hues do that automatically. Blue-shift in the morning, red-shift in the evening.

[quartz wren]

So it only needed 2 input connections

Pretty sure that book was from like the 60s

[wooden schooner]

yes but how many lumens are your hues

[stray wind]

Not nearly enough for you 😄

They're not as bright as I'd like either.

So I end up adding more, heh.

But they are not very bright in the grand scheme of things. Not sure if that'll get better with time or not.

[wooden schooner]

I am so grateful to have discovered how helpful it is to my body to have tons of light of the right temperature.

[stray wind]

Yeah, agreed there.

[wooden schooner]

only in hindsight would I know to say that I have very significant SAD

[quartz wren]

I wonder if it's possible to make an RGB bulb using fluorescent elements with red green and blue phosphor...

(for higher brightness)

I mean I'm sure it's possible just wonder how crazy the idea is

(with individually dimmable elements of course)

[dusty citrus]

Like a CRT TV?

[quartz wren]

I mean yeah basically but inside of a fluorescent light bulb

And if we're going with that analogy a single set of phosphor dots

[dusty citrus]

just thought about 3 tubes within a bulb

[quartz wren]

Yeah, that's what I'm thinking, with dimming hardware that's PWM controlled but powered by mains

No way to try and make a test article currently but could be fun to explore when my lab is more assembled

Getting it paneled when I get back in town next week

😄

[dusty citrus]

nice

Lab here is made up of wood paneling and Polyisocyanurate foam boards.

[quartz wren]

Currently I have a lean to with no walls, half the roof shingled, and not a whole lot of space, plus my bedroom. New lab is getting paneled with repurposed sheet metal from the old barn my neighbor tore down when he bought the property behind us

[dusty citrus]

oh, a separate building

[quartz wren]

And I'm going to completely seal the place so I can eventually tinker with closed loop life support

[dusty citrus]

this room is a semi-temporary closed off space of the small garage.

[quartz wren]

Gotcha, yeah we don't have a garage or I'd probably be using that

[dusty citrus]

Got the rest of the garage for "dirty lab work" for the go kart.

[quartz wren]

And the old shed I was going to use as my lab my brother decided he was going to just squat in and take over so my mom says I can build one from scrap material

[dusty citrus]

nice

[quartz wren]

It's about 99% framed mostly just needs an overhang on the lower part of the roof and then I can panel it

[dusty citrus]

built the current shed back in 2019, better and much more inexpensive than buying one.

[quartz wren]

Yeah the pre built sheds are crap

[dusty citrus]

yeah

[quartz wren]

And really expensive

[dusty citrus]

1200US$ for materials and it is built like the rest of the house

10x10ft inside iirc

[quartz wren]

Yeah I've put no money into my lab so far and it's at this stage

This one's going to be about that size ish, the far section in this pic is my parents' storage space for mid-organizing but when they're done apparently I get the whole building

I think the total building is like 196 square feet

Or something around there

[dusty citrus]

that's pretty good

[quartz wren]

I mean this is my current space that isn't my bedroom https://i.imgur.com/pCqrkHR.jpg

So yeah pretty dang good

(it's a lot more cluttered now, this was a mid-build pic)

The lower edge of this roof likes finding heads

And for those thinking "that looks a little wonky" yes. Yes it does. I didn't use a tape measure or a square. Just a hammer nails and a hand saw. Oh and a table saw for ripping 4x12 beams into 4x4 beams

As this was initially just meant as a smoke shack but it kind of became my outside lab

[dusty citrus]

Got AC in here so the computers' environment stays one temperature and have a relatively low humidity.

remembered from work that I discovered that eDP is somewhat hotswappable

not recommended but sometimes worked

[quartz wren]

yeah, I'm thinking I'll probably build myself a heat pump as part of my life support

not super hard if you can find an old fridge / freezer with a functional refrigerant pump that someone is already going to get rid of

please don't take the pump out of someone's refrigerator they use

[dusty citrus]

hmm, also against EPA regulations if HFC, HCFC, or CFCs are released into the atmosphere.

[quartz wren]

true, which is why you find one charged with non-CFC refrigerant, so don't go too old on your sourcing

because if you're rebuilding the loop you will be simply venting it rather than trying to reclaim in most cases

okay almost time to head out

It is great you can create a campaing

At the website to create a well, if it reach a defined amount of money, they make the well that they constructed in the place you choosed and send the photos to the page of your campaign in their website.

There are places that water is very dirt to drink and when you build the well you give oportunity to people to have acess to a more healthy life.

With clean water.

[delicate stream]

[jovial path]

It seens like impossible that there are people that drink water that is so yellow of dirt but this happens and these wells can prevent this from happening.

[lusty fossil]

lots of folks get cholera from dirty water, it's one of the biggest killers in the developing world, by a wide margin

[jovial path]

A lot of wells are built and the water from then is very better than their local water.

And they also give support mantaining the wells working

And it create local jobs

[delicate stream]

Well water is local water, although it tends to get some filtration from the water seeping down... but wells can also have toxic things seep down into them too

[lusty fossil]

I imagine they do testing first to be sure it isn't more of the same problem

but I don't actually know

[jovial path]

@late fulcrum when you went to New York did you walked in front of Charity Water building?

[tardy badger]

My kids don’t understand much, they are very young.

I imagine my parents are proud

NC State has one of the best engineering graduate schools in the country. I’m excited to add the prestige to my resume

Top 25

[delicate stream]

Time, money

Getting a Bachelor's degree is expensive enough

[quartz wren]

I just meant learning. Learning is free if you know where to go. Just credentials that cost you.

Time I understand

[delicate stream]

My brain skipped lines and forgot what I said, lol... was thinking PhDs. But yeah, creds cost sooooo much money

[tardy badger]

Interesting enough, if you already have a full time job, in most cases Pell grant will more than cover costs for tuition and books

[quartz wren]

But as I said learning is free so should be everyone's goal to learn everything they take interest in

[tardy badger]

I had a difficult time working and doing school full time. 16+ hrs a semester ends up being over 50hrs+ of course work and whatnot

But you can also reduce your costs by getting an associates of science from a community college first and then go to a university

[quartz wren]

Which is the route I was taking when I found out school doesn't work for me

[tardy badger]

It’s not for everyone, that is for sure

[quartz wren]

Also I had chapter 35 benefits so I was going for free but my psyche can't handle it

[tardy badger]

Unfortunately the work I want to do requires higher Ed credentials

I currently have a B.Sc. In Computer Engineering

[quartz wren]

I'm just building my own thing because other companies won't a) use my potential or b) pay for my abilities without creds

[tardy badger]

And also 3 associates degrees lol…

[quartz wren]

So I'll make my own company and just market straight to consumers

Because I'm not going to waste my talents working a menial job or wasting time and sanity trying and probably failing again at a degree

[tardy badger]

I’ve always been entrepreneurial which is why I have my company Oak Development Technologies. But I’m winding it down for a while to get my masters so I can relaunch a more focused and commercialized product with the credentials I need for people to take me more seriously 😛

[quartz wren]

I don't care who takes me seriously I'll do my thing seriously regardless.

[tardy badger]

Wishing you success

[quartz wren]

Thank you

[tardy badger]

It’s hard, and as long as you are willing to put in the efforts to make progress, even small steps, you will always have new lessons to learn and experience will come your way

[quartz wren]

This is the hope. Learn and do what I can until I have finished serving my time in this meat prison.

[delicate stream]

40 hours of job, 50 hours of school, so 90 hours a week of working... this is fine

Close to the other house where my mother lived

there was a coconut seller that appeared once a week

and it was so good, sweet and with a lot of water.

What is the difference between precision and exactness…

[dusty citrus]

The real question is: is human conscious experience as 'special' as we seem to think it is. ;0

@late fulcrum how do you call that white part of the coconut in english?

[pearl rover]

there's always a jaiden animations moment that's relevant

[dusty citrus]

precise here would mean well-aligned; exactitude means identity (one and the same)

[quartz wren]

Exactness = precision + accuracy

[dusty citrus]

construction of a physical item is precise but not exact; manipultion of abstract geometrical ideas can be exact.

[quartz wren]

Precision is repeatability of outcome, accuracy is how close you are on average.

[late fulcrum]

I think the white part of the coconut is called the "meat" in English.

[quartz wren]

Yummy nut meat

❤️ Coconut

So exactness is the combination of getting the right answer on average combined with ability to repeatably get the same answer to arbitrary levels

[dusty citrus]

we don't saythe precise same thing but we do say the exact same thing

[quartz wren]

Yes because precisely the same means they could be different answers but same precision

[dusty citrus]

targeting games like archery use this kind of vocabulary to describe results

[quartz wren]

Clustering is precision average distance to bullseye is accuracy

This is the example we were given in Chem 100

[delicate stream]

I keep getting Discord badoop badoops but there are no notifications

[quartz wren]

So if all your arrows land at about the same spot but off to a corner you're precise but not accurate. If you've got a spread across the target but it averages to the bullseye you are accurate but not precise.

Woooooah I just had a really cool idea

A mirror that passively levels itself and a laser pointer bouncing off of it onto a sensor. This is now a seismometer

[delicate stream]

I think there are seismometers that use something like that?

[quartz wren]

Probably

I got the idea by setting my phone on something wobbly and looking at the reflection of the light off of the screen

[late fulcrum]

That's how a light beam galvanometer works

[quartz wren]

To check how much zinc is on the surface of a nail?

[quartz wren]

Pretty sure the wind is the universe's way of telling me I don't belong in this universe. It always picks up at just the right times that it seems like an intentional attempt to get me to leave.

Knowing my luck and my history, as soon as I get to space solar wind will just do the same. But to greater detriment

Nah that would make it too easy to abort. The universe will just wait until I can't abort to start doing that.

Or you know, knowing my luck I just won't make it to space and will be bombarded by ever worsening wind storms as the planet's health degrades due to parasites it produced itself.

Sorry I'll get out with the negativity and find a better place to channel it.

[dusty citrus]

you could just erase it.

[quartz wren]

I could but that feels cowardly. I've said how I feel, I'll leave it at that. If mods feel like erasing it I have no issue with that.

[late fulcrum]

The Orkney islands of Scotland are now generating more electricity from wind than they can use, and the excess is still more than the 40MW tie line to the mainland can carry.

[dusty citrus]

'Cowardly' is a bully's concept. Run-away is a time-honored strategy.

[dusty citrus]

Paramount Plus (aka CBS All Access until recently) is showing Daria .. just saw S01E01 last night. Holds up well.

[quartz wren]

I just realized that what I see in myself as cowardice I see in others as reason...

@dusty citrus thanks for the perspective shift

[dusty citrus]

;)

They told us we judge ourselves and others harshly. ;)

Basically the epithet coward does not expect to be challenged.

That's why it's a bully's word - has no force at all if you come after them for using it on ya. ;)

(it has a specific meaning in actual war that's not related here)

[wary herald]

You 🤬 poultroon! Why didn't you try them! 🙂

[dusty citrus]

My mom used :

Coward, take my coward's hand

That's the only inscription on it that isn't a statement of facts such as DOB and name. ;)

[delicate stream]

Interesting...

[quartz wren]

Soooo @dusty citrus not sure if it was intentional but you've just given me a major paradigm shift so immense I literally have to take today off to meditate...

(good thing)

I think I finally understand the key to unraveling my own self-bullying and ridding myself of it.

Thank you so much ❤️

Honestly just seeing it as self-bullying sent my mind for a loop...

And I intend to rid myself of the mindset of "I am my own worst enemy" that I've seemingly clung to for years.

This is going to take a lot of work but the process has started

[delicate stream]

Not bullying yourself can be hard

[dusty citrus]

@quartz wren Look at it as self-parenting. You play both roles in that (child, and parent).

[quartz wren]

Woah... You just hit on something a therapist told me a while back that I didn't really understand until now... Because I didn't have a lot of parenting as a kid (too many siblings to get proper amounts of attention from parents growing up) I needed to begin parenting my own inner child.

And it never really made complete sense until now when I realised I would never speak to a child the way I speak to my own inner child.

If he wasn't sick, it would be Well Eagle Fireworks...

Wellegal??

[delicate stream]

Or just Eagle Fireworks

[quartz wren]

If there weren't fireworks the eagle wouldn't be ill

The opposite of illegal is wellegal

Jk it's actually DDT

[pearl rover]

the eagle is ill from making ill eagle fireworks illegally without requisite safety equipment

@quartz wren I finished the handheld, just need to cut the screws i was using in half so i can close the case

Solder joints on the USB port and some pins are awful, and the wiring is abysmal, but it works

Wanna see?

[vagrant sonnet]

Sure

[subtle fable]

Everything about the build quality is bad, because i had nothing to hold the parts, i soldered everything by shoving it onto a table and praying it didn’t move, so there’s too much solder, too little solder, and everything inbetween, but it functions and that’s all that matters

[tardy badger]

Not bad

[delicate stream]

I subscribe to the "cable management doesn't matter if you can't see it" philosophy. Particularly if its something you're planning to build, seal, and never open again

Besides... I've seen WAY worse. One time I saw someone with like 100ft of cable in a space that small because originally they had all the parts spread like 1ft away on a table, and just soldered it all as it was and shoved it in

[subtle fable]

I’m gonna be honest, never done anything like this but i’m surprised it works

Now I just have to figure out how to close it, probably gonna cut the screws in half because they’re sticking out, all because the screws specified were somehow too big to fit into the holes, when they were the exact same size as the ones i was told i needed

[delicate stream]

hmm

[subtle fable]

After i get it closed all i have to do is set up retropie and load some games onto the card

[quartz wren]

Noooooice! Now I'm getting antsy to get back to tinkering lol

Crazy storms at home and I had a bunch of my lab stuff staged in my lean to... Which doesn't have walls... And I'm out of state...

Just need to make sure I get out of the habit of sitting on my feet because that's what got it out of whack in the first place

[tardy badger]

I’m guilty of that as well

[quartz wren]

Done it since I was a kid... I hate wearing stuff on my feet but my toes get cold...

So I tuck them up under me to warm them up and next thing I know hours have passed and I can barely stand

[tardy badger]

I don’t like the texture of the ground under me feet so I wear socks and shoes nearly constantly

[quartz wren]

I love running around on gravel barefoot... I might be a little weird... Also something I've done since I was a kid

Also climbing barefoot is soooo much easier

[jovial path]

Inspiration 4 is landing.

[jovial path]

I think it's amazing the isolation of the capsule

because the outside must get very hot with the friction with the air. I think it must be the same isolation of an airplane?

But before the air, there was the space and the speed could be very high because there was no friction with the air.

I think they put vacuum on the walls of the capsule, between the walls.

[quartz wren]

The capsule is shaped so that the plasma misses the walls

(as well as being passively aerodynamically stable)

So the brunt of the heating is experienced at the interface to the heat shield which ablates off and creates a cool pocket of gas between the shock front and the rest of the heat shield

Like the Leidenfrost effect https://en.m.wikipedia.org/wiki/Leidenfrost_effect

But on a larger / hotter scale

[terse estuary]

Well the ablation is an aspect but my understanding is the main reason the heating is minimized is that the shockwave where the air actually gets compressed and heated stays a bit in front of the surface of the heat shield

[quartz wren]

Bow shock!

How could I forget bow shock? Lol

But yeah regardless it forms a protective sheath of cooler air around the vehicle
