How do I get an LED to pum?
I want to make an LED circuit that pums, like the Solar Powered ones, but without the solar cell that powers it and the way that it turns on when it's dark. What I eventually want to do is hook it up to joule thief and power it that way. The simple reason for this is because I don't want the LED on all the time or flashing just on/off, 'cos I find these too harsh on the eyes. I have tried in vain to try and glean the circuit from other diagrams, mainly because I am a circuit n00b, so instead I thought I would turn to the brilliant minds at Instructables.
Thanks in advance,
The link to the solar pummer circuits.
