-Is D+0+34 the same set up as D+0+22 expect using a different circuit? Is it easy to switch on the fly?2017-03-22
-9V battery with wire to short leads. Wire should have minimal R so that all the heating is in the i^2r in the battery (r the internal resistance). It would be good to know 1) the rated (and measured if time) internal resistance and 2) the battery capacity (eg. NN mA-h). 2017-03-17
