Hey LPF! Anyone recognize this LPM? I found it in an e-waste area and it seems to be old... It's too bad I can't find the detector to plug in to test and see if it's working. I was just curious if anyone knew what kind it was/if it would be possible to construct my own detector for it :P I did...

I'm doing some research about analog vs TTL drivers and modulation and such and am a little confused on some points. Clarification would be most excellent :) I've always imagined analog as perfectly smooth; why do many analog lasers/drivers list a speed in KHz or pps? Is analog not perfectly...

I'm looking for some bigger green lasers to put in my RGB setup :) I'm offering my new RGB driver(s) as payment. Anyone interested? Feel free to post/PM offers. -Alex

UPDATE: The pinout on the voltage regulator in the upper right hand corner is has a mistake in the silkscreen and thus many of the shipped regulators have failing voltage regulators. Note that this only can hurt the IC/voltage regulator itself and will not be the cause of any laser diode...

EDIT: They are now for sale HERE: http://laserpointerforums.com/f39/awlegos-rgb-laser-driver-has-arrived-65086.html This was just the feeler, if you want to check out the new and improved specs and might want to order one, see the link above. I have been working on a full color PWM driver that...

Hey LPF! I've been thinking about making my own version of FML's full color driver for people and selling it. When I wanted to make my own RGB and RGV systems, I would have really like to have been able to buy one of his drivers and it was a pain to design my own. Seeing as he is no longer...

Hey I was browsing CPF today and came across a cool sticky for those who wanted recommendations for which flashlight to buy and thought we might be able to make something here. Too often I read the SAME posts about "which green should I buy?" or "is this company good?" or "should I buy this"...

Thought I might share a bit about my new RGB :) It uses my own version of FireMyLaser's full color driver. I heat-sinked the LM338's though so they can run at up to 5 amps without worry. I love all the effects that this thing has! There will be fans attached to each heat sink. I just wanted to...

Hey LPF... I need to vent after killing a few more lasers. So I'm building a sweet RGB array with custom everything - drivers (FML style with effects and everything), heat sinks, fans, variable power for all the colors with the 445 pushing 1.5W. I am on a time crunch trying to get it done for...

I was talking to someone who said they worked with 465nm lasers... so I had to see if it was real. And sure enough: Cookies Required Anyone else ever seen/worked with this color laser? -Awlego

I love reading the forums, especially on threads that I have posted on, but find the subscription method to be rather tedious... while automatic subscriptions may be undesirable, I would find the option to subscribe to a thread when I post to be an enjoyable feature. Don't know if it's...

I have a LM317 based DDL driver set up with two 1/2 ohm resistors in parallel to set the current to 500mA. Problem is, no matter what resistor(s) I use, the output is always ~160-170mA. Even if I take off all resistors it still outputs at 168mA... which is really weird. I have double and triple...

So today I was playing with my 2 mirror spirograph using both a single green module (unknown power est. 50mW) and my adjustable RGV when I noticed something odd. When I used the spirograph to make shapes with the laser, not only did the design change, but the color appeared to change too...

How far into the IR spectrum can you see? Or how deep into the UV spectrum? I haven't had any chance to test if I can see anything below 405nm, but I have some IR LED's and I can even see a faint red glow with 100mW of 940nm light :) Just wondering what the range of other members' vision is I...

Hey I've been a member for a while now and have been reading the forums for a while before that, but have never formally introduced myself... My family currently resides in Chicago (moving to Denver next year though :D ) but I will be attending Caltech (California Institute of Technology)...

I'm interested in getting some lithium rechargeable batteries for my various lasers for a couple reasons: 1) Cost - over time rechargeables will be much cheaper 2) AAA alkalines just can't handle the current needed for some of my lasers (specifically the green modules) I'm planning on getting...

Is it possible to use a Micro Boost Drive V1 to power a 100mW green module? I broke the standard driver when I removed it to try to fit it inside a little flashlight. :cryyy: The minimum voltage for the driver is 2.7 volts, and the minimum output is that of the batteries (so 2.7 volts is the...

I built a homemade phr build in a flashlight using the new Micro Boost Drive V1. It is set at 135mA and worked great for several hours of use time over a couple of weeks. It lit matches almost instantly and was quite impressive... but now as soon as I turn it on it dims almost instantly to maybe...

Plan: Put a 90mW green module in a small metal flashlight host. Past experience: In a previous build with a 25mW green, I used washers that aren't a perfect fit, but are close enough to keep the module from moving with the help of a touch of super glue. They work fine and the laser never heats...

Woot! It's up and running. I took some pictures of the semi-finished product. I really like the finished look. The alignment of the beams still isn't quite right (it's more than a bit hard without sightfx's kit - but still doable) so I will take it apart to fix that eventually, but I wanted to...
