Thanh, that's a nice job and looks great with the paintwork. Do you know how much your little DC generator puts out.

Hi Trevor !! DC generator output about 1,5 V, I have to add increasing volt circuit !!

Interesting Thanh, I thought it would be a little more than that as most LED's I have tried require around 3volts to be seen clearly though some do come on at a lower voltage but not 1.5V. That is quite good mate.

I take it that the increasing volt circuit is the one you showed on a couple of our posts, because they were pretty good.

increasing volt circuit can use about 0,5 volt ...it is ok for stirling engine low speed !!
