You have to be pretty clever to get resistor,capacitor,diode circuits to do anything super special, but if u have an oscillator supplied, I think then u should be able to do the rest of the machine with this.

Start off with a carbon print, then electroplate copper onto the surface of the carbon, with copper sulphate and some copper scrap. (So u dont need to sell your copper when you scrap it, just keep it to yourself!!)

Once uve plated the copper, then if its embossed where the diodes are, then u put it in a bowl of vinegar with the diodes poking into it, and then ull form the acetate and hydroxide where the electroplated copper particles are.

Then if u do a second one, without the rusting, you can press them together, and then u have diodes.

get the resistors via structure (skinnier and longer) (and maybe u dont copper plate on the resistors, you leave them as carbon.) + capacitors, your limited to a low amount of farads, but u could probably put some kind of glue down where the caps meet and press them together.

Then thats resistors, capacitors and diodes, all by yourself! And with an external oscillator, I know how to do an amplifier with it, but without that its not a complete solution by itself.

Ooooo...kaaayyyyy....

Resistors currently cost me a penny a piece (less if bought in quantity). How much does it cost to 'make' one? (given that my time is currently valued at $150/hour).

Open question.... anyone still not convinced the OP is trolling us yet?

yeh but how much did it cost to hire the pick and place machine?
and buying raw minerals is always cheaper than buying manufactured goods, its a completely different kettle of fish, its always going to cost less.

Dont know about that Ratstar guy, but his ideas are pretty good!!! =)

I wonder what happened to the poor guy?
