Couldn't have said it better, Yogi.

Isaac Asimov reincarnated :D

Aren't humans animals too? :q

actually there is a big debate about it so right now it is an opinion for now though

+ko animations There is no debate.

@@crashthestash Well, I've asked my parrot to etch my pcb and so far he's just shit on it with a lot of squawking

+Blenson Paul hey ,if anyone else wants to learn about introduction to electronics pdf try Elumpa Circuits Expert Alchemist (do a search on google ) ? Ive heard some extraordinary things about it and my mate got amazing success with it.

best way to learn!

Yes, I've done that in the old days. Time consuming. Could not do that for the connections of today. 2017

eddebrock are you a nincompoop? I hope not.

eddebrock great! thats the first step of learning

eddebrock This is a homemade circuit board manufacturing process.. a board such as that's inside your own computer or PlayStation. After having done making the board, one can 'solder' electronic components on it. You can make your own radio station or a satellite receiver or whatever you want.

😂😂😂😂😂

@@kardelsharpeye1380 whats a nincompoop?

mendebil True my friend

UVs produced by sunlight aren't constant on the board, which means that you don't really know what the actual exposure time should be.

Sometimes it does not sun shine and need to practice when the sun doesn't shine.

bcz it is 100% homemade.

I followed this video, but instead of using a CFL bulb I used a halogen. I put the board after it in the developer, but it came out exactly as it was, like nothing happened. My board was sold as photosensitive, it came with the protective sticker, but never looked green or blue. Just copper color. Do you think only the lamp was the problem? After putting it into the developer I killed the photosensitive layer, right? So I cannot repeat it with a CFL and the same board? If I cannot: can I still use the board with marker / iron method? Thanks a lot in advance!

He's a subtle comedic genus, hehe

Emmanuel Essandah how did it go?

Send me pic .

Emmanuel Isanda any follow up?

@@dilbo_swaggins3957 Yeah he died... Drone to the face

anything?

What type of black paint, if I may ask? Thank you.

comming from a noob: i think that it might have some sortof insulator on the connecting parts

The whole plate is made of a special type of fiber glass which is an excellent insulator, it's coated with a thin layer of copper, the copper that is etched away leaves wire like connections glued to the fiber glass plate.

i thought it was obvious?

Awesome! I have been waiting my whole like to learn that, thank you.

aaron selby from what I've gathered : The whole plate is originally one copper plate. The design imprinted into the photoresist is a negative of the finished, desired design. The transparent parts of the pellicule are not the traces, they leave light pass to the photoresist,which dissapears, leaving the copper exposed to be eaten away by the etchant. The parts of the pellicule that are left opaque are the traces. They block light, and the photoresist remains. That photoresist protects the copper from being eaten away from the etchant.

Thanks so much!

thanks, totally works, and no special disposals

Except you are making Cupric Chloride which is harmful anyways... Also when you add salt, and see those fumes coming off? Thats Chlorine Gas.... A Chemical weapon. So be careful.

now there you go, you saved some and killed more including yourself

How long does it take to do that. Sounds interesting though. I don't know what the recipe for that.

Warren Brown, where is the chloride coming from in this approach? From the board itself?

+John Tsiombikas You're right. I had been etching PCB's for a longtime with sodium persulfate and it took almost 30 mins. That stuff is also pretty expensive, it had been a longtime since I done an electronic project. I will start with this hobby again soon but with better equipment. Better solderstation, using silkscreening to create professional PCB's. I'll also make a DIY etching tank with plexiglass. It's very cheap to make one yourself instead of buying one.

Table salt speeds up the reaction and can pep it up if it starts to slow down.

John Tsiombikas have u lost ur mind ? Ur crazy

Why is a twenty minute wait time a "joke"? I'm just considering that the board(s) could be used for years, so spending twenty to thirty minutes during this step of the manufacturing seems a reasonable investment - especially when compared to the many days or weeks it cane take for a third party manufacturer to produce the board(s) for you. I also feel that the satisfaction for creating your own circuit board(s) should out-weigh the whole process. If, however, you wish to mass produce your board(s), then certainly try other processes in order to reduce manufacturing times. I feel the bigger picture here is that anyone can create their own circuit boards, and even their own circuit components, at a low cost. What does it really matter if we need to wait minutes or hours to do so? The process of creating your own components, and thus the feeling of accomplishment, should - in my view - balance the effort required.

Note: Don't put too much hydrogen peroxide in the solution! Using too much hydrogen peroxide can result in the production of chlorine gas, which can be deadly if not well ventilated!

Andrew Waters how do you dispose responsibly?

Literally put it back in the bottle it came from. Most of the copper will settle as sludge. There's no need to dispose of it for a very long time.
