Yeah 9v. It shouldnt drain it after like 30secs. My rckstr driver on a 9v will run about 30min total run time. I dont know what the deal is, Maybe I got a bad driver. I ordered a new driver and some more LPC's last night.
Just LED'd two LPCs. Set it 3.4 (same as the rckstr) and worked fine for a sec then went out. The other LED'd as soon as I turned it on. Guess its back to ordering more LPC's.
Sorry, I was throwing that out there as the power I will be using. Ok, Ill try 300ohms or little less and see what it does.
Also going to pick up a 1ohm resistor and try that to verify
Thanks for the quick replies. so I divide 1.25/30=0.04166666 x 1000 is 41.6?????
So using 9v and measuring the thru holes what resistance should I see to get around 400-420mA?
I recently purchased a modwerx adjustable driver to run my LPC-815. Im having a hard time getting this thing adjusted correctly and dont want to LED my LPC before I hook it up. Im using a 9v battery for the power source. With the driver disconnected from the power source, Im mearsuring the...
My 50mW green was left in my car over night and now everytime I go to use it, it has to warm up. After about 1min it will starting shining bright. Whats weird is, even in my house now I can sat it down leave it for 2-3min then go to use it and its cold to the touch and once again takes time to...
One of my older TVs will glow. In a dark room with the TV off you can move the dot all over the screen then turn the laser off and you can see lines like above where the laser was.
I got one I built set at 124mA and have had it built for about a month with no heatsink other than the aixiz module and its still going strong. I havent ran is straight like above but I mess with it daily
SOLD!!!!!
Im selling one of the first lasers Ive built, its a PHR-803t LD, radio shack project box host, radio shack momentary button, aixiz module, rckstr fixed 101mA driver, all driven by a 9volt (not included since its my rechargeable). No heatsink due to with 101mA you can keep the laser...
