    Broken Charger outputted 1.5V to various Lithium cells

    I have a charger which seems to have crapped out, and is outputting 1.5V. Before I noticed something was amiss, I ran a few 18650s through the charger and it all those batteries now read varying voltages, from 0 to 2 V. After throwing away that charger, is there any way to revive these cells...

    Something seemed off. I was using the equations from here: Certified Laser Safety Glasses Confused the 0.001% with actually reducing it by 1/10,000th when it fact, OD5 reduced by a factor of 0.00001, 1/10,000, 0.001% or a 3.2W laser to 0.032mW or safe levels. It's one of those days.

    What OD rating should one get for the 445nm 3W diodes that we are tinkering with? Edit: Techinically O.D 5 will bring down the power of a 3.2W to 3.2mW. So O.D 5 or higher?

    FS: 2W 445 nm in gorgeous Old Gold Host

    Hey guys, This is my first attempt at making an old looking laser with the 9mm 445 diode. I had a lot of these parts sitting on my desk for a few years and only now got back into it, so I'm unsure which lens I have on this thing. It's a DTR 9mm 445 package with xdrive set at 2.4A. It's pulling...

    Current Problems on 9mm diode and 2.4A driver

    Sorry today's been a long day. I got the 117 dollar option from your site and using it as is.

    Current Problems on 9mm diode and 2.4A driver

    My mistake... it is a 2.3A driver. I am running it on two of the previously mentioned cells. When measuring at the cap, I remove the cap, and complete the circuit by putting my ammeter in series with battery to body of host. The driver/laser/batteries seem to have a warmup period. Current...

    Current Problems on 9mm diode and 2.4A driver

    Hey Guys, I bought 2x9mm 445 packages from DTR with a 2.4A x-drive driver. I didn't verify the output of either driver. Now I built the laser, and heatsinked the driver very well. Turn on the laser and LPM it, only 1.9W. So I measure the current at the cap, and only get 1.8A:thinking: So...
