How can I build 220 vac transformerless 12v car battery charger and jump starter using only triac and diodes?

Out of curiosity... why would you want to? Sounds like an awful lot of work for a battery charger... I mean you can buy one pretty cheap.

I want to build a 9-10 battery charger that can operate off my cars charging system.?

We Answered:

Just buy a NiMH charger that works off 12 volts. You can buy it off the shelf. Modern cells are more fussy about being charged correctly so you might as well get somebody else to do the work for you.
