Variable DC power supply
« on: April 05, 2009, 02:34:54 PM »
Hello-

I am wanting to make a variable dc power supply
I have sort-of an Idea on how to do it but I am still confused.

2. can I make this for under 20$?

thanks in advance

PS I sent admin an e-mail about making a tutorial and he hasn't responded for about a week
I don't want to sound impatient but I really don't know if he got it.

If you put "SoR" in the topic he should have gotten it.

And if you want to make a variable DC pwr supply you can use an LM1117T which is an adjustable VR.

did you put sor in the emails subject line? also pm would be good. but bear in mind he is a busy man so dont send him 500,000 emails. one pm should be fine as he comes on here fairly often. and was the tutorial about you wanting to put one up, or him make one?
