Stu, this is the second Group Buy round for these (I received mine from the first GB). If you peruse the board a bit you will see that Daedal has an excellent reputation with lots of successful transactions. I would certainly not hestiate from purchasing from him.heliosphan said:Hi all
Daedal, I'm VERY interested in buying one of your lasers, I'd like to ask a few questions though-
I have an electronics bench power supply of which I can set (via two dials) the voltage up to about 30v and current limiter up to about 3 amps.
I'm hoping I can just hook up a bluray laser diode (your diode in an Aixiz module) to my bench PSU, set the controls 'carefuly' and give it a good test, would this be suitable prior to developing / buying a laser driver circuit?
If so, settings wise where would I begin? I'm thinking beginning at around 4v, current limited down to maybe 10ma, then begin raising the current limiter until it begins lasing.
Where would I stop increasing it though? I'm thinking perhaps shortly after I get a 'satisfiable' beam.
I've spent a bit of time doing electronics projects (not professionally trained though) and have learned a lot, I've even designed and built a Microcontroller house alarm system (PIC 16F877A and PICBasic!).
I'm also obviously wary about handing over some cash to somebody on the other side of the planet who I've no idea about. There's never been any justifiable way to prove the legitimacy of this sort of thing other than visit u in person! And unfortunately I'm not heading to the US any time soon!
Other than this, I'm thinking of just risking it for about 50 usd! (about £25 my money) Cant be sure yet.
Only trouble is I'm in Barcelona (I'm from the UK) all next week at Microsoft IT Forum Europe for work, so I wont be all that into choosing shelling out for a laser diode or not! :-/
In the mean time I'll have a think about it. I love the idea of having a 'mostly blue' laser, and I can make out to people it cost me the price of a PS3!
