This one is designed to boost 12V up to 200V. My previous circuits to do that were all flyback designs using off-the-shelf parts.

#

Winding giant coils from super thin enamel wire is fun :D

tardy badger
#

Are you making a toroidal type?

late fulcrum
#

No, I'm not attempting a toroid, this is an ordinary two-piece pot core transformer with cylindrical windings I can do on the former, then assemble the ferrites onto it.

tardy badger
#

Oh okay cool

#

Toroids tough

late fulcrum
#

I like toroids, but prefer to pay someone else to make them for me.

tardy badger
#

Oh that’s not bad

spice moss
#

what if you print them?

static flare
#

i used to be really confused as to how those are made until i realised that the wire probably has an enamel coating

late fulcrum
#

Yeah, it just looks like bare uninsulated wire

delicate stream
#

Have any of you ever done paper-shield transformers?

late fulcrum
#

I'm not a fan of stripping magnet wire, but then I discovered solderable insulation magnet wire, where the insulation just turns into flux at soldering temperatures.

spice moss
#

i have seen plasma channel use uninsulated wires to coil

static flare
#

I've been working with electronics for too long to not have realised that sooner

delicate stream
#

lol

#

There are types of transformers without enamel insulation

late fulcrum
#

There's this one with a fiberglass insulated primary and an uninsulated secondary of copper ribbon

delicate stream
#

Pretty

Seems like it'll be a transformative experience for you then, @late fulcrum

Random idea: Pi Pico as a USB VGA adapter? Plug Pico into PC via USB, use it to drive a VGA display for the PC?

#

yknow how JP made a camera shutter button with the neotrinkey? could also totally be done with the neokey, plus you could make it clicky

delicate stream
#

I did not, but that's smart

static flare
#

it was when he did the neotrinkey as the product pick

delicate stream
#

Ah

#

I missed that XD

I wonder what this week's Product Pick is

#

I just realised I'll have like, $900 when my tax return comes, because I've been treating it a bit like a savings account (cause I don't need to pay nearly as much as I do)

delicate stream
#

Yay!

static flare
#

but that isn't until july

delicate stream
#

Boo!

static flare
#

just lets me put more money in

delicate stream
#

Yay!

static flare
#

I technically don't make enough to need to pay taxes

delicate stream
#

... yay? boo?

static flare
#

although, it does mean I need to cut down on the adafruit orders

#

I'm adding an extra 20% so that I'm putting in a quarter of the money i get every fortnight into taxes

turns out the outlets in my school cafeteria are wired wrong

delicate stream
#

oof... did they release the magic smoke when you plugged something in?

orchid zephyr
#

nah

#

they just didnt do anything

#

turns out live and earth were swapped, so there was no power in the two prongs

delicate stream
#

Ah... At least you didn't have a hot ground!

orchid zephyr
#

no, i did.

#

i just had a device with only two prongs

delicate stream

Oh, oof

had i plugged in anything with ground it would have been worse

Hi everyone,
This is a transcript of my presentation over at the European Microwave Week 2020, actually held in 2021. You can find the video here and the slides here. I’d like to thank Frank van Vliet, general chair of the EMW, for inviting me to do this talk.
The words have only been edited lightly - it is still presentation style, so here and ...

yeah, because it can be crushed on shipping

I get those yellow SMT boxes from Adafruit with most orders.

#

None have arrived broken.

delicate stream
dusty citrus
#

I have like 30 of them or more. ;)

delicate stream
#

Ohhh, maybe I should get those...

dusty citrus
#

I gave my brother two of them (so he could interlock them) to see what he'd do with 'em. ;)

delicate stream
#

I kinda just want to print all my storage going forward

static flare
#

those are a little large for me, usually, so I'd probably go with a smaller set, but just seeing they sell them is great

I realized my Circuit Playground Express says Developer Edition -- do they all say that, or am I special? :O

delicate stream
#

"hey dummy, why not check the product page and see if the one they show has it?"
Oh yes it does, durrr

static flare
#

I wanna get some of the free stuff but I also realise that's gonna cost me heaps and it might be better just to buy them at cost

#

cause to get the playground, it's like, $385 AUD before shipping, which will probably add about about $70 AUD

delicate stream
#

You don't get the free shipping? D:

static flare
#

That's for continental US customers only :/

delicate stream
#

Oof...

static flare
#

shipping for orders that big is like, $50USD+

delicate stream
#

Probably should just hit the first 2 goals and buy tht CGE outright

#

If you really really want one ASAP

#

Or wait for another big order when you have more muns

static flare
#

Yeah, that seems much more financially accessible

delicate stream
#

I'm not hitting that top goal again any time soon XD

static flare
#

There's a whole bunch of stuff I want, if I were to buy it all at once, it would cost ~$700

delicate stream
#

Oof

#

Ye a lass of expensive tastes

static flare
#

I mean, there was like, 68 items in my cart

delicate stream
#

Adafruit is a dangerous place for wallets, lol

static flare
#

eh, my birthday is in June so I might just share my wishlist to some people close to me and they might buy me some stuff

delicate stream
#

My birthday is also June :D

weary fiber
#

June & May have so many birthdays lmao

delicate stream
#

There's a correlation with seasons

weary fiber
#

side note, someone just tried to threaten me with doxxing?

delicate stream
#

What?! Someone from here?!

weary fiber
#

problem is... on every profile, I give fake addresses/personal info in the bio

#

so they threatened me with a fake address that I purposefully made public

delicate stream
#

Not smrt

weary fiber
#

Felt like a massive brain moment

delicate stream
#

Lol

#

But if it was someone here... Notify mods

weary fiber
#

oh nah, was on reddit

delicate stream
#

That's very no bueno

#

Ah

static flare
#

oof

weary fiber
#

still, I've kinda been waiting for that moment

delicate stream
#

Lol

weary fiber
#

I literally never divulge actual personal info, but I leave lots of decoy info everywhere

#

but I'm also pretty public about being a furry

#

just for those few golden moments of "you think you doxxed me? omae wa mou shindeiru bruh"

delicate stream
#

Big smart

#

Lol

ancient kindle
#

has anyone used these?

#

they look really nice, but idk if they're nicer than the pile of esd tweezers I have accumulated

stray wind
delicate stream
#

I use flush cutters as tweezers sometimes

ancient kindle
#

living on the edge eh

delicate stream
#

Indeed

ancient kindle
#

I think I'll get em

#

just to get something with aligned tips lol

delicate stream
#

looks at crooked tweezers, coughs

ancient kindle
#

yeah they bend like crazy

#

probably cause they're the lowest quality metal possible

delicate stream
#

Mine will NOT bend, at all, but they were joined out of alignment

static flare
#

just had a conversation with my fiancee as to why i need to spend the money to have someone do my SMT parts for me

#

(i say just, it was a while ago, she's asleep right now)

delicate stream
#

"If you enjoy my current level of sanity, this is a requirement"

ancient kindle
#

I'm too much of a cheapskate for that

static flare
#

mostly cause I don't have the coordination or eyesight for small parts, nor the soldering ability, but if I got a reflow oven it might be easier

delicate stream
#

I'm gonna build my own pick'n'place eventually

ancient kindle
#

ovens do make it much easier

#

just place the stuff

static flare
#

These are prototypes, so I don't want to put the time into doing it, especially if I've designed it wrong

delicate stream
#

It might cost a bit more muns, but you can recoup that in sales if you sell the thing

static flare
#

exactly!

#

but like, i might get into doing it by hand if i need to for costs

delicate stream
#

Hand fun

static flare
#

but for prototyping, i don't mind it being a little more costly, just to save the work

delicate stream
#

Yee

static flare
#

actually might see if I could get it made soon, I'll order the Adafruit parts i need for it next time I get paid (cause the PCBs are going to take a while anyhow)

delicate stream
#

:D

static flare
#

Technically it only needs headers, both male and female, and a JST connector from Adafruit

delicate stream
#

SMD headers or thru-hole?

static flare
#

Wait they make SMT headers?

delicate stream
#

Indeed

static flare
#

that's actually insanely helpful for this board, I might actually be able to condense the size and better position things

delicate stream
#

:D

static flare
#

Ultimately I want to see if I can put stacking headers on the outside at all, but I'm really unsure about that

delicate stream
#

Which board was this we were talking about? fuzzy brain memory

static flare
#

The super secret project I've been working on

delicate stream
#

Ah, that one. checks notes

@ancient kindle I have that set of Rhino tweezers, along with other Rhino ones (different shapes, ends, etc). They're fairly nice. Only complaint is their printing on them is a bit smudgy. But they work rather well.

I also think Hakko's CHP brand of tweezers are the bee's knees too.

#

Hakko makes some really high quality & affordable pliers, tweezers, cutters, etc.

ancient kindle
#

they make tweezers too?

#

I have the flush cutters, pliers, and wire strippers

delicate stream
#

I will learn all the pins

limber jackal

that's a mood

delicate stream
#

Just buy all the things forever, they'll come in handy eventually

And never throw anything out

I look at having a rich variety of parts in inventory as risk management, and a source of creative inspiration 😉

Adam Savage would agree XD I often adopt things in need of homes...

What font is best font?

polar bloom
#

Topaz

delicate stream
#

Sharp

#

I like OCR A Extended

weary fiber
#

unironically, comic sans

#

it's chad-tier for low resolutions

delicate stream
#

Honestly I think Comic Sans just gets too much hate

#

Meme hatred

polar bloom
static flare
#

I don't dislike it???

delicate stream
#

Oh, hey, it's Comic Sans after getting a degree and a proper job

polar bloom
#

If we're talking old school fonts, I like the one from IBM daisy wheel typewriters.

delicate stream
#

They had a few font wheels, lol

#

I think it was a mix of OCR compatible and more human-liked fonds

#

Forget what the default was

polar bloom
#

Yeah I don't remember exactly which wheel we had.

delicate stream
#

I had an IBM Selectric II and III, which were the ball style, and had about a dozen fonts for each

polar bloom
#

It's been ages but I think we had a Selectric II, but just the one font.

delicate stream
#

I miss mine...

polar bloom
#

I just used to type on it for fun. No idea what happened to it.

delicate stream
#

I used to use mine for retro stories when I needed to get into a time period mood. I used the Selectric II until it died, and the III caught fire

static flare
#

I love monospaced fonts

delicate stream
#

Monospace fonts are life

#

Sans Serif

then this message will be well received

I have to use a function key on my keyboard cause I don't have it on my 60% keeb

delicate stream
#

Oof

#

100% kb + numpad for lyfe

#

60% keebs look super nice & minimalist though

delicate stream
#

120% keeb forever

static flare
#

I mean, I don't need a numpad or like the fancy other stuff, I barely use the F keys

delicate stream
#

MOAR KEYS

static flare
#

I actually want to make a keyboard with F1-F24 tho

#

maybe even just a macro keypad

#

just for the function keys

delicate stream
#

I need to figure out how to make a Windows key to put on my Model M without modding it

#

I'm getting tired of realizing I did Ctrl+Esc instead of Windows on keyboards that have a Windows key

static flare
#

I mean, I like it, but it makes me uncomfortable

limber jackal
#

I mean, if you need moar keys...

static flare
#

But like, the C64 doesn't have more than 8 function keys

limber jackal
#

Old XT keyboards only had 10 "F"unction keys, in 2 columns and 5 rows on the left side of the keyboard, at least in US/ANSI layouts

delicate stream
#

I've considered getting an XT keyboard with moar function keys, but I can barely fit my Model M on the desk

limber jackal
static flare
#

gdi now i want it

limber jackal
#

lol

static flare
#

It has a card reader

limber jackal
#

I'm sure it can be found used for less. For really wack-a-doo out there commercial keyboards, just search for "POS keyboards"

#

I'm pretty sure some must approach the 200 key count

delicate stream
#

moar

static flare
#

I mean, it can have a card reader

delicate stream
#

MOAR KEYS

limber jackal
#

Card reader - for when you can't be bothered to type your Driver's Licence/ID or credit card number(s) yourself, or use a password manager to make it easier!

static flare
#

hahaha

delicate stream
#

For security, you can have a set of cards that need to be swiped in the right order to unlock the machine. If you don't swipe them in the right order, then it deletes everything. If you do a specific wrong order, the house explodes

#

Gotta keep them secrets safe!

limber jackal
#

House explodes, but since it's a POS keyboard made to be used and survive disgruntled angsty teenagers ringing up rude customers, it will survive

delicate stream
#

... why does it download a file instead of playing the video

#

WHAT IS THIS

static flare
#

is it a chord keyboard using a guitar hero style keyboard

delicate stream
#

No I mean the video downloading instead of playing

#

I gathered it was a keyboard guitar, lol

static flare
#

i meant the guitar keyboard

#

it's from 2009

with an apng, you can do tricks with layers to do something quasi-like keyframes for h264

Actually we should just use .mov for everything

.tiff is not a good format for pictures

but maybe pdf/a 1.0 is better?

I like RAW+JPG

I thought QuickTime on anything was atrocious

slim shard

the format is probably better than they let on, but I won't pay mactax to see it, and I won't use it if thats the only way to do so

it was apparently the basis for mpeg 4

Get somebody you trust, to operate the car. Then have them let up on the brake (engine OFF) on a slight downhill. Try as hard as you can to hold the car back from rolling onto your position.

That'll give you some appreciation of the inertial mass of the missile you're about to launch at pedestrians.

@tardy badger @polar bloom thanks guys. One day ill get to say its completed lol

dusty citrus
#

@velvet pelican I try not to impede trucks going uphill when I'm on my bicycle. They earned their climb and me being inconsiderate of their inertial requirments causes a lot of extra stress on their mechanical systems.

#

OTOH if I'm in a climb and have been at it for a while it's not my fault if someone gains on me, starting from far away and out of sight. They can just wait.

#

There's a narrow road rated for at least 45 MPH - with a huge whup-whup-whup punishment etched in the pavement for crossing the double-yellow (center) line.

#

People will routinely cross that line rather than apply their brakes.

#

It's like they'll do anything to not use the brakes.

#

At least on a bicycle it sounds terrrible when they cross that line - really loud.

#

Maybe it doesn't feel like much inside the vehicle.

Hello

I'm used to doing stuff like this

^actual soldering iron I used

#

overall not a terrible experience if you take surface tension into account and use gravity to your advantage

delicate stream
#

Yup, the tiny guy is good for SMD! Man that tip looks rough... but if it works, it works!

quartz wren
#

tip has since been changed, actually right after I did this because taking pictures of it up close showed me how bad it had really gotten

#

and I had a few spares around so no reason not to

#

I think I just got so in the flow (excuse the pun) of soldering that I hadn't noticed the level of degradation

I need a new tip for my 15-45W iron, the one it has basically melted, lol

The way I was describing it to my new team at $dayjob is that I started out wanting to make light up solar-powered toys but in order to do that you need to know a bunch of things about 3D printing and laser cut acrylic and electronics and switching power supplies and everything, so I keep going off on side quests.

#

sad day...I just remembered I gave my friend all of my copper sulfate and I need some for electroplating a paperclip...

#

I will have to improvise...I have plenty of copper metal I can figure out how to dissolve for them sweet sweet copper ions but I need to find a way with the things I have

#

I think I can do it with vinegar, salt, and a bubbler

#

(or peroxide, but I don't want to be wasteful)

#

I'll have copper acetate then, which I should be able to use

#

mmmm smells like some salt and vinegar kettle chips I had the other day

#

on second thought, going to try this without the salt because I had a realisation that while this is a good way to dissolve the copper quickly, electroplating with the salt still in the water is a recipe for a chlorine gas disaster

#

sodium hydroxide would be a better way to get ions in there to kickstart dissolving it with the aid of current flow, but it turns out I gave that away as well

#

thinks for a moment and decides to just go for it with the acetic acid as the electrolyte for current-aided dissolution

#

where to find a high current, low voltage source of power...

#

my bench supply that I built from a PC PSU got commandeered by my brother to give to his girlfriend at the time so that one's out

#

lol

#

all my 3D printer supplies are 12+ volts

#

probably only need a couple amps tops at 5v, might be able to get away with a phone charger brick and a USB cable that's ahem reterminated

#

just need one without smart handshaking circuitry in it

#

which I had, but seem to have misplaced

#

screw it I'm trying the one that came with a USB-C cable and seeing what happens (no, not "reterminating" the cable that came with it, just finding another one and using its port)

quartz wren
#

turns out the peroxide is going to be needed to make it any semblance of a short reaction...

#

because bubbling it would be slooooow

quartz wren
#

electroplating seems to be working 😄

#

need a larger surface area sacrificial electrode though

#

got it

#

I'll use a piece of veroboard

#

I just heard 3 car alarms go off in rapid succession, should I be worried?

#

almost sounded like a soundoff from the neighbors

#

specifically the ones who try to control the block with their politicking

#

if anyone's wondering why I'm electroplating a paperclip, I decided to make a micro soldering iron for SMD purposes

#

already formed a nice tip with a file, did a chemical surface cleaning to smooth out the jagged edges and give a nice pitted surface at the same time for nucleation sites of copper crystals (in theory)

#

and now I'm just waiting for the copper to deposit

#

protip: if you need to pause your electroplating cycle, remove the item you're electroplating completely from the solution or you will redissolve the layers you had and be sad

#

either that or it didn't adhere well and I knocked it off when I was stirring the solution

#

this may be an overnight project

quartz wren
#

I guess I could use a tip entirely made from copper but with how thin it is I don't know how long it would last

#

yay! I had a discovery!

#

iron electroplated with copper accepts solder very easily

#

which in turn I'm hoping to put another layer of electroplated copper onto until I feel it's robust enough

#

okay, making 2 variants, one with a pure copper tip (with ceramic heating block) and one with an iron core, electroplating, soldering, more electroplating, etc.

#

curious to see if I can do this with a crappy dollar store mini screw driver

#

and then put a heating element around it

#

would give me a nice solid SMD chisel tip

#

hmmm

#

it would seem that much like thanksgiving dinner, when it comes to electroplating, agitation is integral

#

I have successfully tinned a miniature flathead screwdriver

#

turns out you could probably use this method to make springs solderable for the thing someone was talking about in #classroom

#

without needing to go with the extra supplies / effort required for crimping them all

#

okay it looks like 2 layers makes it pretty robust, time to assemble it and program some firmware lol

quartz wren
#

Tip complete, will pick this up in the morning

#

Just commoning the grounds on the heating element and the thermistor to reduce wiring requirements and mount the thermistor more firmly to the chassis but also the heating element is soldered to the back of the heating tip with tension on the wire so if there's a runaway thermal effect it will auto-disconnect

#

and the thermister will give a direct reading on the tip temperature (more so than it would if I left it where it initially was on the outside of the ceramic, now it touches the metal)

#

aaaand now I have a bunch of copper acetate to use for future electroplating tasks

delicate stream
#

Electroplate ALL the thing!

#

it was embarrassing

hasty quarry
#

Ah

hasty quarry
#

I lack control, and shake a bit

quartz wren
#

hence why I have extra trouble with fretless instruments compared to the usual

I don't know much in the way of others' songs on piano...I just go into a flow and play what comes to my fingertips

hasty quarry
#

So...I assume you know theory to be able to do that

quartz wren
#

not formally, but I know enough

#

I taught myself partially from some lesson books we had when I was growing up

#

and learned the rest I know in choir during high school and college

quartz wren
#

one of the requirements to audition for choir was to read sheet music to a piano piece and I barely knew how to do it for singing so I asked if I could take a few minutes to plunk it out...got the go ahead and apparently I nailed it when he came back

I got a pennywhistle as a gift from my friends a few years back as a cheap silly thing because they weren't sure I was actually going to use it...within the day I was playing all sorts of things on it and the next instrument they got me was a ukulele

which was basically a toy and kept going out of tune so I bought real strings and tuning pegs

hasty quarry
dusty citrus
#

I think he just meant he was about technique - muscle memory maybe would be the approximate.

hasty quarry

dusty citrus

Maybe the opposite of improvisational?

#

I kind of knew what he meant because he was contrasting me with himself. ;)

He said I had a better ear.

as far as I know "technical" in the music world just means you're very keen on theory

I think he was the one who was big on never (ever) 'practicing' .. he said you always play your very best, each and every time.

When I was a kid, I managed to get an old oscilloscope. I enjoyed it and its wonderful big 7" screen for a long time, but it got thrown out. I finally got another one on eBay, and have been restoring it. After swapping out a whole lot of old capacitors and resistors, I got a dot on the screen but no sweep. I eventually realized I had omitted a jumper but when I installed it, I didn't have the dot any more. I traced it down to a failed plate resistor in the horizontal amplifier. I don't have the right high voltage high power precision part so I ordered one, but I wanted to see if I was close, so I tack soldered in some "close enough" resistors from the junk box and violà! I get a trace and sweep!

During the lockdown, I've kept myself sane by fixing the pile of broken scopes I've accumulated over the years.

#

I've attempted some fairly advanced stuff, figuring I have little to lose. I had previously never attempted to reattach a base to a CRT.

The base cement involved a 150°C bake to cure it

#

I found a replacement CRT online for $225 but I'm not going to spend that kind of cabbage to restore ... this

I figure if I fail, a garbage scope is still garbage, and I've learned something. If I succeed, I get a working (if obsolete) scope and I've still learned something.

delicate stream

And with the cool cases and knobs of scopes like that, you could always repurpose upon failure -- put a Pi and a bunch of advanced stuff in that old casing, like a sleeper device, lol

I currently have a monochrome CRT from a piece of old optometrist's equipment that I've been playing around with for a couple years and it's still fun

#

I'm thinking one of the versions of my game console is going to be put into there since I'm making the graphics pipeline resolution-ambiguous until the actual output

#

(thus allowing me to send the same rendering data from the 3D calculation unit to either the rasteriser connected to the CRT or one connected to a VGA driver, or one that's connected to a TFT...or whatever else I implement)

#

point is I'm implementing obsolete tech wherever I can because it's fun

#

much more understandable as far as being able to hold the entire design theory in mind at once and be able to reproduce it in theory (and soon in practice, learning how to make a CRT from scratch)

since the voltage measurement isn't precise

anyway, sharing to let people know that mistakes are normal, and as long as nobody got hurt and you learned from it, they're actually a good thing

Obviously the keeb needs thermal sensors and cooling to prevent burns during operation

quartz wren

this is why when I have the means to buy components and equipment, I like to get spares when I can...

delicate stream
#

Cooldown time is part of why I like my USB soldering iron -- I can just touch it to something metal and it cools in seconds

quartz wren
#

well, the tiny iron I'm putting together seems to be working great so far, but it holds temp because of the thermal mass I gave it as part of its mounting

#

and it way overshoots

#

but that's just PID tuning

#

and it's good, means that this thing will heat very quickly and readily to replace the heat it loses

#

but I'm still dubious about the cooldown...might take an old heat sink and use it as a cooling pad for when I'm done with a session

#

ever soldered to a steel screwdriver? was playing around with electroplating and seeing what will accept solder afterward and had nothing but success

#

going to prototype another SMD soldering iron using this with a slightly different design approach

you might just be able to see the thermistor taped to the handle

This project is kinda insane and I love it

#

insane projects are basically my thing

#

I get bored easily

#

if there isn't a good chance for things to begin smoking furiously, I lose interest

#

(not true, I guess moreso if there isn't a chance for great excitement)

#

because I'll sit for hours on a logic design project just to watch the machine tick away in harmony

#

and to me that's exciting

#

but uh...funny thing, I ended up hooking things up wrong when testing and one of the pairs of wires somehow was passing a crapton of current at 12v and only through that pair of wires...the heating element didn't heat up but the wires began smoking

#

luckily they were insulated with fiberglass

#

I think the smoke was oils from my skin

#

check your wiring, because that smoke could've easily been the magic smoke from inside of a MOSFET or worse, the microcontroller

#

I think the only thing that saved the circuitry was the length of the wire making it have enough resistance to not act like a short, but like a heating element instead

Pro protip: don't disassemble lithium cells XD

ancient kindle
#

Brb going to my basement

quartz wren
#

I know it sounds tempting, but if you're going to disassemble lithium cells, get a certification and a job doing so for a recycler...

#

not worth the risk without hazard pay

ancient kindle
#

So

#

Supercap spot welding

#

Yay or nae

quartz wren
#

I mean, if you're looking for pops and booms, that's the way to go 😉

#

(and have it be relatively "safe")

#

heh...opening up cura to enter gcode commands to my new soldering station 😆

ancient kindle
#

wh

#

Gcode

#

Soldering station

#

How

quartz wren
#

I'm making my own using 3D printer parts

#

just remembered cura doesn't have a readout back from the printer...gotta use the arduino serial monitor or smth

quartz wren
#

just had my first power fault on it

#

lel

delicate stream
#

Poof?

quartz wren
#

good thing the PSU I'm using is from an xbox and has fault protection

delicate stream
#

yeet

quartz wren
#

no poof, but I think I need to redesign this

delicate stream
#

No poof is good

quartz wren
#

pretty sure the thermistor is way too far from the heating element

delicate stream
#

Close is good

quartz wren
#

it keeps overshooting even with ridiculous PID values

delicate stream
#

I think usually it's within like 2-3mm from the heater core?

quartz wren
#

the cartridge initially had it between the heater and the ceramic

#

probably going to place it there again

delicate stream
#

Sounds like a good idea

quartz wren
#

good news is it's definitely able to melt solder 😄

delicate stream
#

Progress XD

quartz wren
#

post mortem analysis says the solder I was using to hold things together inside definitely melted

delicate stream
#

Lol

#

I wanna build an electronic "surgery robot"

quartz wren
#

feel free to use any ideas from this project you find useful

#

for instance, making a tiny robust soldering tip with an electroplated paperclip filed into shape

delicate stream
#

Lol

quartz wren
#

anything I can manage to do with my scraps, anyone who has a little budget can do tenfold

#

yep that thermistor got toasted...must have way overshot on my last heating cycle and just completely shorted things in there

#

XD

#

good thing for spares!

#

so what made me realise I could probably solder with 3D printer components was when I ended up heating a hotplate up so much it desoldered its own power wires

#

if you had spring terminals, you could make that into a reflow oven

#

(spring terminals to conduct the power so you don't melt the attachment point)

#

oh the rest of the hotplate after that mishap? completely fine.

delicate stream
#

I feel like you like burning things :P

quartz wren
#

I mean, yes, but uh...I also like not burning things sometimes......RIP keeb

#

I might just move to using the screwdriver design, but idk...

#

apologies in advance if I become too much...I have a habit of over-sharing and it tends to crowd the channels I talk in...

#

if it does become too much, feel free to tell me to give it a rest and I'll buzz of for a while

quartz wren
#

alright, thermistor repositioned, fingeres crossed

#

holy crap it works!

#

right out of the gate with the PID values I have in there

#

checks what they eventually settled on

delicate stream
#

Huzzah!

quartz wren
#

ah, was the defaults I pulled as an example from the Anet A8 as a sane set of values

#

makes sense

#

better run a proper calibration though because it overshot by a degree

#

better than overshooting by double, then maintaining at 10C higher than the set temperature

#

it's in range for a PID autotune 😄

#

just gotta throw a few gcode commands around and hope for the best

#

but it doesn't seem like it's going to temp fault like it was doing

delicate stream
#

Yay!

quartz wren
#

be careful not to short out your heating element wires...especially if your emergency reset button is sitting behind them...

delicate stream
#

Oop

quartz wren
#

luckily I managed to miss it on my way to the e stop

#

and luckily I'm still using fiberglass insulated wire

#

but it's very clear which one is the heating element wire now as it has acquired a darker hue

#

hmmm...well it didn't like that...couldn't cool down fast enough for the PID autotune to complete

#

guess I'll just proceed with a bit of over and undershoot

#

okay it's holding stable at solder melting temp, time to try soldering something

delicate stream
#

Good luck!

quartz wren
#

I see a few problems here...firstly, the tip temp is lower than the readout temp...second, the solder I'm testing is still the same solder I'm attempting to use as thermal mass and binder...

#

and last, the wire I chose with the fiberglass insulation, well let's just say that it heats up a bit while the heating element is active

delicate stream
#

I don't know if you can use solder to bind the heating parts

quartz wren
#

it hasn't failed yet 😉

delicate stream
#

Lol

#

yet

quartz wren
#

also, the actual wire to the heating elements is twisted, not soldered. the solder holds the tip inside the ceramic heater core

#

still not a great idea but I don't have thermally conductive epoxy

#

well, it's been holding at 220 for a bit, but the problem seems to be too low thermal mass

#

it might work for tiny pads

#

but I don't have any SMD projects to actually test it on

#

¯_(ツ)_/¯

#

well I learned some stuff

#

yeah....the solder definitely melted inside the heater core

#

I just pulled on the back of the tip and it came out and splattered solder on the test article

delicate stream
#

Oof

quartz wren
#

oh well, guess it's on to the screwdriver prototype

delicate stream
#

Yay experimenting

quartz wren
#

oh boy that was still hot when I grabbed it

#

luckily I has teh ninja reflex

delicate stream
#

Owie

quartz wren
#

maybe I should just take a 3D printer heat block and repurpose it...

#

it has facilities for the heater core, thermal mass, and a way to add a threaded tip

#

as well as the thermistor

delicate stream
#

Not a bad idea

quartz wren
#

in fact, I could probably solder using a brass nozzle...

delicate stream
#

Might be a little blunt XD

quartz wren
#

I have some pointy ones somewhere

delicate stream
#

Lol

quartz wren
#

but no, I'm going to bore out the nozzle to jam the tip I made into it

delicate stream
#

XD

#

Elegant

quartz wren
#

I appear to have misplaced my tip...which is bad because it's very stabby and covered with lead

delicate stream
#

Oof

quartz wren
#

okay we're good, it hid under my keyboard

delicate stream
#

The one it murdered? XD

quartz wren
#

no, the replacement one

#

also it was my main soldering iron that murdered it

delicate stream
#

Ah

quartz wren
#

and to keep the tip in? I'll just put a bolt on the back end to act as the heat break, mounting point, and tip retainer

#

(into the other side of the threaded hole from the nozzle)

#

Beautimus

delicate stream
#

Lol

quartz wren
#

I made a boo boo...I accidentally cut too much off the back end of the tip

#

may need to make a replacement

delicate stream
#

Oop

quartz wren
#

actually...it comes just above flush with the back of the nozzle...this might be usable

delicate stream
#

:D

quartz wren
#

Looks kind of menacing

#

yes, that's lots and lots of melted plastic on the heat block

#

it has had a good life

#

(pretty sure this is from my very first printer, before I worked out the kinks and how not to crash your head into your print or have ooze out of the block because of improper sealing)

delicate stream
#

Lol

quartz wren
#

can't seem to find my metric bolt set

#

found something that will work better though

#

it's a titanium pin that was poking into my skull for 3 months

#

halo braces are no joke

#

but they let me keep it

ancient kindle
#

You had to get a halo brace?

#

That sounds horrible to have on

quartz wren
#

yeah, neck surgery when I was a kid

ancient kindle
#

6-12 weeks of no head movement

quartz wren
#

C1-C2 fusion

ancient kindle
#

At least it was as a kid

quartz wren
#

hooray for blocking out childhood memories! /s

delicate stream
#

Oof

quartz wren
#

Lookin spiffy

#

time for a break and then a test

#

but I have high hopes for this

delicate stream
quartz wren
#

Heh I found another term to apply to my acronym

#

Faulty Brain Syndrome
