A ghostdrive isn't something I can make, is it? I definitely want to buy some kind of small driver to put one in a more elegant host, but right now I just really enjoy building all of it I can. Just for fun. :)

I have got the diode in a pretty big heatsink. I didn't feel any kind of heat come off it. Here's the schematic I used: Step 3: Driver All the solder joints should be strong. I've had trouble in the past with shorts in my drivers due to the copper strips in the particular board I bought but...

I didn't notice any of the components getting hot either. The lm 317 usually gets pretty hot but I put a homemade heatsink on it. I didn't check it though. Could the capacitor put out any residual charge DURING its running time? I thought that was more something that happened as soon as you...

Whenever I first hooked it up the batteries read 7.84 V. Should I test them while they are hooked up and it's running?

Yeah, I dialed in the output current with a test load before hooking it up. It was at 366mA. I did not short out the capacitor though. But if there was stored charge that could kill it would it have run correctly at first like it did? It ran well for a short bit of time. I turned it on and off...

Also, I powered it with two 3.7 V trustfires.

Here's some pictures of the drivers I've made:

Hey guys. I recently had a LPC-815 build running with an lm 317 driver at about 270mA. It worked nicely for about 3 months then all of a sudden went dim on me. I thought the diode went out so I bought a new LPC-826. I modified the driver to give me 380mA (a little below the suggested current...

Thank you. Of course there never really is a way to do something other than going through and actually knowing the theory. Thanks for the link!

Ok, I would love to get some help to make a driver to put out 380mA of current. I made a driver to run a LPC-815 diode that operated at 270mA but now I'd like to use an LPC-826 and I've read that they run at a higher current of about 380mA. What can I do to modify the circuit I have used to get...

The only thing I can think of that's wrong is that the trimmer isn't resisting anything. I think maybe I have it maxed out, I'm not really sure how to adjust these things properly.

Here's some pictures: 2 of the PHR setup (doesn't work) and 1 of the LPC (that works).

Thank you guys so much. I'll attach some pictures of my setup, and also of my successful red setup. I did NOT change the test load to account for the PHR. Oops. I will definitely do that. But that doesn't change the amount of power the driver is putting out, right? I thought I had looked it up...

Hey guys, I'm putting together a driver for a PHR-805T diode. Here's the instructions I'm using: Step 3: Driver Now, a few months back I put together the same set up for a LPC-815 red diode and it works just fine powered with two TrustFire 14500's. But I'm putting together the same thing...

Hey guys, just for fun what do you think is a good place to get a decent blue pointer? I found this one: 100mW 405nm Stylish Mid-open Blue-violet Laser Pointer at Laserpointerpro.com I'd like to get one with a fair output around 100 - 200mW. Any advice?
