Here is what you will need along with part numbers from http://allelectronics.com
TX-12625 $20 power transformer
FWB-352 $2.50 bridge rectifier
EC-648 $0.65ea( you need 2 of them, so $1.30) 680uF capacitors

LCAC-129 $3.00 7.5' power cord
ACS-3 $0.65 plug for power cord


Note: Don't use this with SLA batteries(like the robot battery). The charge curent is way too high and it will signifiganly shorten their lifespan.

Tell me if you(or anyone else) are/is interested and i will post a schematic.

Yes, I would be interested in this... maybe if you have some time, could you also post some of the basic theory behind how it works?
