I saw this on qualifound, and was wondering if anyone was up to test it?

50-400mA

Damn, nice find. This would be great for cheapa$$'s like me. I'd love to see some more specs on it. Like, how much voltage input and output. If these can drive PHR/all blu-ray and/or the LPC or other diodes, all for only $2.3 each...... !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Edit: I knew it was $2.3 + shipping, but... I would've thought it'd be a combined shipping charge. :( . It's more like it's $6.3/each. However, it's still an awesome deal if it works. I kinda wish I tried these out instead of buying 4 drivers from rkcstr (no offense rkcstr - I know it's gotta be a pain for you to make those drivers, esp. when we could get them already made by machinery and for a lot cheaper).
 
If someone good with testing components wants to test it, I'll pay for it. Obviously I don't want to pay for someone who has no knowledge to play with it, but someone like Dave might want to have a look

It seems like it'd be quite simple to test. Just hook it up to an LPC and put an ammeter in series with the diode. Then you can measure the amperage, and for the voltage across the diode, use a separate voltmeter. I'd think it'd be best to start off with 6V - you could use a lab power supply so that readings stay exact - and then turn the pot, and jot down the current readings and voltage readings. Then, for PHR, you could run 9V and do the same thing, BUT I wouldn't recommend turning the pot after you see the current hit 130mA - you don't want to burn out the diode.

Edit: Maybe before you start running 6V through testing an LPC, maybe it'd be best to just run the driver not connected to anything, and see the voltage drop. Or, at least hookup the diode, but slowly increase the lab power supply starting from like 3V just so that you could see the voltage drop on the driver.
 
I'd be happy to test these if Qualifound send a couple to me as a sample, and I have access to an oscilloscope, so I can see current ripple etc, as well as the basics.
 
Hey, I'd pay for a couple, and if you tested them, and they wer awesome, and you wanted to use them in your builds, then you could buy them off me, or if you don't want to, send them onto me?
 
Sounds like an OK idea - FYI, I am replacing the PHR in your Kryton now, so I will PM you when I have finished.
 
we serioulsy need more specs about them. they look good... and great found, i just some days ago asked Faona bout developing ttl/analog drivers!
 
Yeah, and this'd be an easy GB too. 100 purchase and it's only $230 total (free shipping when you buy 100). Could re-sell for only $3 since postage is CHEAP - can prob be in an envelope.
 
Thx jake! I copy the specs:

# Constant Current to 500mA
# TTL modulation 0-5VDC <5kHz
# 3-12VDC Supply - Laser diode dependent
# 0V off & >2.5v laser on
# On-Board Potentiometer for Current adjustment
# Power supply will drive all laser diodes, RED, Infrared & Blue


2.5V TTL is kinda weird...
 
I just looked at the Qualifound website for the drivers and it says

50-400mA.... :-?
