never used it for this kind of experimenting but it acts as the transformer and the chips and parts in circuits need pos and neg 5 volts now days.

I'd need the connector on the board anyway. That's sure to make a bang, without reservation. :) ----- Original Message ----- From: Bryan Schulz To: programmingblind@xxxxxxxxxxxxx Sent: Sunday, February 22, 2009 4:08 PM Subject: Re: using breadboards hi, you should go to radio shack and get the little white blocks with hundreds of holes, and a few packs of the stiff bendable wires. they are different lengths and colors with 1/4" stripped at each end and you use those wires to jam in the holes along with other parts to build your circuit. you could use a spare atx computer power supply for the power.

I'd like to start off with something small, possibly a battery charger or something similar. I found a small tutorial on instructables, but not totally sure how to get going. It explained how things work somewhat, but not accurately enough for me. It mainly used pictures to explain, which didn't do me a whole lot of good. Any ideas on how I can set this up? I understand the polarity--hooking one negative end to the positive etc so that the circuit forms a loop, I'm just not sure how to do what I want. So, here's my idea. If I figure out the layout, I can set up a power cable going from the outlet to the breadboard. Then I can place in jumpers to bridge the gap. I can take the 120 volts down to 9 with some resisters (?) and hook a battery pack to the other end that will charge the batteries. I'm thinking I'm way off, but... ideas would be great. If I could, I'd like to set it up so it'd charge like 4 at once, then I could cut down the 120 to 36. Possibly put in a heat sink to keep it from getting really hot.
