You know you can make your own fiberglass backed copper pcbs with a toner printer and an iron right?
That way you won't start a house fire when the highly combustible glues and solvents in cardboard heat up too much
>>52270004
This, holy shit op what are you doing?
You could always print your own pcb since forever.
Just go to your local hackerspace.

Too expensive
>>52269999
Why is it triggering your goyim sense? Can your delicate eyes only tolerate threads about GPUs and builds?
>>52270004
What the fuck are you on about you dumb cunt..
Cardboard is fire retardant.. It takes over 200c to burn it...
>>52269965
Why bother making a PCB when I can just program a $3 Arduino clone?
>>52270048
wat.
>>52270048
No, only some cardboard is fire retardant
Most isn't
That's why it makes such good kindling
>>52270047
How is $10/large pcb expensive?
Ffs you can get double layer for cheap now too
>>52269965
thanks ahmed
>>52270047
The fuck you're on about? I made dozen of this beauties back in shool and I didn't spend more than I earn on 1 day of job.
>>52269965
>PCB
I'll grant you that that is circuit and seeing as it's based on cardboard, what you have there is a circuit board, but I don't think any part of it is printed.

$4 for 10 pcbs
and it is <$10 for a 1 gallon jug of muriatic acid for etching (takes longer than other etchants but still works for cheap)
if you dont have your own toner printer you can go to your local kinkos and print out your pcbs tracingsfor like $0.05 each
and if you are super cheap and cant afford an iron you can literally take another one of the unprinted pcbs and a lighter and transfer it that way

You should use valves for "warmer" data. Not that transistor garbage.
>>52270047
>Too expensive
You're in the wrong place, poorfag.
Go back to your console gaming forums.
>>52270192
make some etchant for less than $10 (all you will ever need, dont ever need more):
http://www.instructables.com/id/Stop-using-Ferric-Chloride-etchant!--A-better-etc/?ALLSTEPS
as it said in last post you can get 10 good sized pcbs for <$4
are you in elementary school OP?
>>52269965
But aluminium foil and cardboard is cheaper than copper and etchant, plus you have to print too!
This is the only way a NEET like me can have PCBs to mount microcontrollers on
>>52270609
and one of the many ways a neet like you can set your house on fire and kill your family
>>52270609
why not just solder it directly?
is less of a pain than gluing strips of tin foil
What the fuck am I seeing?
>mfw this is the reason why /g/ should stick to OS wars, phones and PCs
>>52270753
Actually gluing foil strips is very easy and by taping the strips after sticking with glue you can make them quite durable, enough to endure a lot of switching of ICs
keep going OP
>>52269999
Quads confirms OP is a shitpost
>>52271319
I tried with tape over foil method
Results are very good, here's a 7 segment display working
Now I can replace the display without disturbing any other stuff too
OP here again
As you all might have guessed this is a proof of concept type of thing, not a complete project, god no. My purpose was only to prove that aluminum foil can be used to replace the wiring in PCBs to make (very) makeshift, but usable circuit boards.
Maybe I'll use this technique to make shitty little kitchen timer kind of thing with an 8051 and foil wires for kicks
>>52269999
Maxim goy detected.
>>52271747
The most amazing thing about this was that the foil, a strip of metal about 0.016 mm thick in length was able to deliver enough current to burn a segment of the display. It might have been because the display was really old but nevertheless this was quite a satisfying experiment
>>52270842
Can you use a pencil? The graphite is usually conductive enough. No idea what voltages you are running though. Low voltage will need a lot of pencil, but aluminium foil just looks like a massive pain
>>52272067
I have already tried pencil graphite
The problem is the huge resistance that it offers. While it is good to use graphite on paper as a resistance, it makes a really shit conductor. Pic related, a 0.1W surface mount LED being driven by graphite rails

>>52271747
No you are an idiot that doesn't know how to make your own pcb and you got caught in your idiocy
Im new to pcb, but to me, it looks like you're doing some type of enchantment to a base board. Set up some +1 resistor +1 capacitor +1 gate +5 circuit etc.
Do you guys feel like you're playing a game or practicing alchemy?
Lets say I glue a coat of aluminum foil to a plastic board and use hydrochloric acid for etching since they produce a reaction.
Would it do the trick? or will it just dissolve the whole thing itself?
What material should I use to paint the circuit on the foil?
>>52272719
I did that shit back in school but frankly never had a chance to do it again
>>52273014
plastic is very lowly reactive to most acids, so what many people do is take a piece of paper printed from a toner printer (which is plastic that has been forced onto the paper using ionization) then transfer it onto the copper plate using an iron (just turning the paper upside down onto the copper and placing the iron on the back side of the paper)
some people I know use expo dry erase markers for modification
or you can use wax
some people also use photo resist paper that when exposed to certain wavelengths of light deposits a plastic onto the surface of the opposite side of the film (which would be against the copper)
hydrochloric acid will work for all metals, at varied speeds, to quicken the reaction in copper you can add an oxidizer like hydrogen peroxide in a 2:1 H202 to HCL ratio
easysauce
>>52273339
you should use polyethylene btw, VERY lowly reactive even compared to other plastics
>>52273243
no you didnt, you are a middleschooler that doesnt have a card of any form yet and cant order a piece of fiberglass backed copper or you simply had no idea you could make your own pcb's and are afraid of being called an idiot so you are back peddling
>>52269965
You can't solder onto aluminum though
>>52273432
you can with roughing and flux but it's a pain
Why can't there be an actual PCB printer rather than all this nonsense of flipping and pushing and dissolving. Just ask for an arbitrary board, wait 30-45 minutes, get your PCB out.

This.
I made hundreds of the fuckers.
Used to hate doing it, but it was a million times quicker to print some shit and develop it in the solution myself than send it off.
>>52273405
Yeah you're right man I agree with every word of yours, now go back to discussing AMD vs NVIDIA
does anyone have that picture of the home made ghetto sound card?
>>52273637
There are but they're expensive, so normal folks who'll use them maybe twice a month can't be bothered to buy them
>>52273637

The home build CNC machine? Hhmmm... that does sound about right, but how would I bind it all together?
>>52274265
>bind?
do you mean the wood plants as the frame?
fucking screws and glue
or are you talking about the copper to the backing, because you would still buy the fiberglass backing
>>52274307
planks*
>>52274307
Copper to the backing. I don't see how the CNC machine would bind those, or those thing come already bonded?

Not really, it just falls off.

OP clearly never heard of a breadboard
>>52269965
ive been thinking about building my own breadboard with a similar method, but in my opinion this isn't a great idea for non-prototyping and permanent designs because aluminum oxidizes mad fast, has a resistivity twice that of copper and cardboard sucks up water like none other.

I dont need to google it, I do it. you need enough roughing to stimulate capillary action, that is the only way to bond it

Back when Minecraft was the hottest game in the block after the discovery of in game electronics and logic gates, I played it just to make calculators and other cool shit. I gradually got bored because it was pretty laborious to build even something apparently basic. During my mania I built graphic cards for 4x4 1 bit displays, full adders that could sum upto 1023 and even a CD like storage medium, god it was such an amazing time

Question is, did she say "Gee En You Slash Linux" or "New Linux".
>>52274403
if you want to bind your own, in factories that bind them, they take dense weave fiberglass and just use resin to bond to the copper, so shouldnt be too hard, though it may be cheaper to just buy it unless you want a really weird shape
>>52275959

>not making your own PCBs with cardboard and aluminum foil
Don't forget to dip your foil in copper sulphate or you won't be able to solder to it.
>>52276854
>Don't forget to dip your foil in copper sulphate or you won't be able to solder to it.
Holy shit that's good to know. I tried soldering to aluminium foil (I had the iron on and there was some there) and was kind of disappointed to see that it didn't work.
>>52275503
Neat. Think I'll make myself a mantis and start experimenting.
>>52276541
I'll begin with the prebound ones and then move to experiment with ways to get the machine to bind them together on its own. Thanks for the info.
