Why can't it drive a red? An LPC-815 @ 3.35v , 450ma will put out 275mw. Check the diode spec charts on the forum.

Ok, I think many are missing the main point of the thread. To many ppl had these and they didn't work. So, I found out why and posted the way they did work, the range , including a table of what to expect. Remember, I used a diode from Vcc to the "TTL" so it came "on" @ 3v - .7v(diode drop) =...

No problem at all CH. All I did was try to define it a little better for more understanding. @ rhd, If you look at post #9 I stated "@ 7v it cranked out 691ma @ 4.27VDC". Ok, looking at the table I posted of voltages and currents, this has somewhat of a voltage limiting on the output. Raising...

Ok, let me see if I can help a little. I didn't get notified there was a question by email. Sorry. If you plan on using this driver you have to have power to TTL. No power to TTL and it will not turn on. Consider it an electronic on/off switch. You can use a regular switch, but this one will...

I can't imagine Chuck selling something like that. If you sent him a pic, I'm sure he'd replace it and probably give you and extra for your trouble. Did you contact them BB?

Did you put the diode in backwards? It has to have +vdc on the TTL or it will not work.

I got one and like most it seems to be abt 50% of the stated output. It's not a bad laser for the price even at that output. If you are wanting a true 200mw....you'll be disappointed.

My "other" diode arrived in Ohio today. Morgan you have a PM. Thanks!

Hi John, I haven't been doing much lately. My 1st order had the 50mw 532nm Green with 5 multiple heads for special effects. The kids and I love it and it will see its way into the small room wall size light show I plan to build. The heads interchange nicely too. I doubt it's 50mw, but it's still...

I'm usually abt 1-2days behind on delivery than the rest of the world....... Hopefully Mon or Tues for me then.

When I was doing the "fun test" of the DIY Digital Thermal LPM I used a IR filter from scontony. It was on one of the cheap overspec pointers that most estimate abt 30-40mw. The DIY unit , with no standard, is really no more than a good comparator. It does work well for % comparisons of power...

I'll let others have 1st shot, but I'm sending a PM to help cover the R&D in case no one jumps. R&D gets expensive, been there many times. Not just in laser stuff.

Way to go guys!

I'm trying to get all the chips I want in a list so I can do it all in one shipment. Always something to add..lol I was looking at the TPS63020 as it has 4A switches. I have more to do than time to do it all! On the power supply.....I bought it off the bay from HK. hey had US sellers but the...

I don't think you have to interrupt any of them John or meant you should. It will work out on its own (by the affected people)IMHO. You should need to say nothing, just expect your results as you were. They are veterans, with some unfortunate times, and I feel they will respond as a role I would...
