I'll have to look into and do a little more testing on buck/boost drivers before I felt comfortable handing them out to people for use on their diodes. It's doable, but probably not in the first couple of batches. I'm looking into it as we speak. This can be done, no problem. Would you rather...

God damn it

Haha thanks. You're not missing out on much, except for the mountain of student debt. Makes for a good morning jog

Hahaha Great, I'll see what I can do. I have materials to produce about 50 boards ATM, which I will use for testing purposes. If they turn out to be good, I'll give those out at very discounted prices* as "experimental" units. In the meantime, rate in order of importance: 1) low min input...

EDIT 9-25-14 **BETA UNITS ARE NOW AVAILABLE. SEE PAGE THREE OF THREAD. LINK TO PURCHASE: Removed ------------------------------------------------- Hello Everyone, Been on a hiatus for a pretty long time, I've been buried under by loads of work. The purpose of this thread is to guage...

Badger is right, the foil will only divert your problems elsewhere. This, on top of the fact that Indium/Gold foil seems to be excessive, you can achieve what you want with some simple copper tape. Get a thin roll, and tape a couple of rounds around the diode housing. Back to the diversion...

Updated the first post with link to finished prototype. Very cool, works, easy to assemble.

Well, Now I'm a fourth year, haha. I guess you can say I've been pretty preoccupied...

Except this doesn't regulate current, it just limits it. Its designed to be used mainly while testing drivers and diodes, like in a benchtop setting, in order to minimize damage. For example, Instead of having your power supply leads coming out onto your desk, have those go through the...

So, in that case, you would set the limit on the regulator lower than usual. Unless there is some nonlinear relationship to the current gain vs. usage, in which case adjustments can be made.

I would beg to differ but I can run some tests. It's a simple principle, if the diode is receiving 300mA, there is at least 300mA coming in from the power source. If, lets say, this current exceeds 350mA, the power is shut off to prevent potentially overdriving the diode. I'll still run some...

The setup is fairly simple: a pair of IC regulators. The pair act separately, one for current, the other for voltage. This way, you can safely test laser diodes and set an initial current limit until you are satisfied with your diode behavior. I.e. You know your diode will die if it draws...

Hey everyone, It's been a while. Just posting to see if anyone would be interested in some "test regulators" I might be getting printed. They would act as a pre "filter" that you could attach to a power supply or some batteries and then to your driver/diode test setup. At a certain...

Reviving an Old thread, but this is in the top search results for "TEC Driver" on google so I'm going to add this link: http://redlum.xohp.pagesperso-orange.fr/electronics/PWM-TEC.html Regards, amk

Oh, good point. It was meant as sort of a benchmark of one's involvement in this hobby. Ill make those questions optional. Also thank you Infinitus for posting on PF! Regards, Amk

Is there possibly someone who is active on any other forums like CPF, PL, etc? If so, can you please help out and post the survey link there too so we can get get a wider array of responses? Still at 14 responses! Regards, Amk

Haha thanks for the responses guys! I have 12 so far, I'll see if I can set the results to be public or something.... Regards, Amk

Hey everyone! Here's a cool survey Idea I had a while back... Basically there are a LOT of different kinds of hobbyists on LPF and I was always curious as to how the demographics span out. (Age to expertise? etc?) So here's a quick "poll" put together, Laser Interest Survey Itl take a...

The new stuff!! Constant Current Source #1 My apologies, I am in class as I type so I didn't read the whole thread. In case it hasn't been posted already, the link above is very helpful. I am using a modified version of circuit #5 with an arduino to run an adjustable TEC, there are versions of...
