My first burner!
Just got a collimator from Robin and with 200 mA through a red diode have my first burner!
I'd been trying to set light to white tissue and the penny suddenly dropped. A dab with a black Biro and flames! It also cuts throught black insulating tape.
I then made a black blob with the Biro on my hand and pointed the beam at it. OUCH!
I'd love to stuff a bit more current through the diode (it'd a red one that came from a Philips DVD RW) but as it's the only one I have I won't. I have a suspicion that it would be good for at least probably 200mW.
A lovely childhood. Just me my mother and the voices.
