Homemade Capacitor

Post by evildragon » Fri Dec 21, 2007 8:04 am

Haha, made a paper capacitor, so EASY to make.

I don't think it performed very well, it held on to that .01v for a bit. I don't have a cap tester either, so I have no idea what it's rating would be, but I assume VERY low.

All capacitors are made of paper and foil. To reduce the size - adding electrolyte.

But Paper Capacitor is the technical and correct term for the type I made, which is just paper, foil, paper, and foil layers tightly wrapped around a stick with wires connected to each foil

Given the price of caps, why would anyone make a homemade one? Isn't that like reading a book about how cavemen used stone axes and making one for yourself?

The learning experience, and just having fun, that's all.

I guess, but "fun" for me would be building a homemade processor, not a homemade cap. :lol:

Building a homemade processor entirely from homemade capacitiors - that's real fun.

You gourmet. Resistance and transistors also homemade?

Homemade diodes are pretty easy - homemade transistors are another thing. :D

I guess you could get by on diode-diode logic. 8)

It would be quite possible to make a DMA chipset (that copy a memory to another memory)... But a homemade CPU that execute nops ^^... haha...

Ho, i'm very away from all those things ^^. I remember my cousin had to make a cpu out of transistors at poly's, it was just doing additions and a few other things, and it was already a "big" project, last year project, many people involved .

Actually, some homemade cpu's exists, based on discrete logic and even on relays. For example, Harry Porter's Relay Computer (415 relays). So, we only must find tutorial 'how to make homemade relays', and we finally learn kung fu.

I made my own 4 bit CPU in college using TTL parts, with EEPROMs for the microcode. That was really fun. :D
