I hear ya'; "didn't let the magic smoke out - so it works". :thinking: As per the other thread, I suppose I should just get a cheap 100mW green pointer, tear the driver out and fire it up with a 350mA Buck with a 12volt source on the other end and see what happens. Maybe throw some 3watt LEDs...

Gotcha. I started a thread on this, but perhaps I didn't phrase it correct. What I'm trying to do is build inexpensive *fixed* lasers using this method - no batteries. I'm familiar with boost drivers and use them with portable LED rigs, but trying to determine if a boost driver is required for...

Do explain how a cheap Chinese driver mounted on the end of a laser pointer and powered by a non-linear power source as a battery is not prone to ripple and transients while a state of the art regulated LED supply is? :beer: I've measured some of my MeanWell LED supplies to the best precision...

Greetings everybody. For the past couple of years I've been building really cool high powered LED fixtures (reef lights, DJ lights, whatever), but have been frustrated when dealing with lasers. Commercial fixed lasers are either uber expensive, or total junk. There's nothing in the middle. Quite...

I messed with HeNe's as far back as the mid 80's, and have caught enough HV pokes to probably have killed some brain cells. The PSUs themselves are well insulated, but the problem comes from the cathode/anode connections with the tubes. Also, the tubes can still nail you when powered off because...

I wanted to try this over a year ago but was told that LED drivers and lasers didn't mix. Seems somebody was full of it. The question is, will this work with high powered greens and reds? Maybe I'll start a thread and ask :-)
