FlexMod P3 Analog/TTL Laser Diode Driver

[edison]

Laserman,

It seem that Dr lava stands behind his product and i,m interested in buying one. If you sell things sometimes you have to answer some questions and respond on a fewcomments from a customer that has doubts. I dont like ass kissing like some people do towards Pangolin. If its really a quality product like Dr lava stated i will let him know for sure.

Good news, they arrived today, I updated the first post with a photo.

mophead, yes I'll be sure to bring a few to SELEM.

You are going to buy a WHOLE ONE??? NICE!!!

Don't go out on a limb too far without thoroughly testing it first.

I patiently await your review on pins and needles This ain't his first rodeo cowboy

hrmm, your comparing a company that sells a >$1500 package to a guy selling $35 drivers?

everyone uses his drivers for a reason

I personally don't feel comfortable running the diodes in series so I bought *gasp* two drivers, one for each diode

Just picked one up, Thanks!

Finished testing and posted a preliminary user manual here:

User Manual

Please read through it and let me know if you have any questions.

edit: already thought of one thing.. talk about what the 'balance' adjustment does.

On the last pictures you could place an arrow where to place the start-up delay bridge.

In the Flexmod2 user manual the word "laser" is no where to be found.
I thought this to be because of potential in/export issues. Maybe wise for the P3 manual too.

Maybe you can add some text mentioning combining the interlocks of multiple flexmods.
You're bound to get questions about that.

If, at any time during operation the laser diode circuit goes open, the driver will shut off output ...until the laser diode circuit is closed and the interlock is reset.

and

Allow 1 minute discharge time before connecting the diode to a previously-powered driver.

These quotes may sound a little ambiguous/contradicting.

There will be a TEC kit soon to be a companion to this FlexMod

Can you give some preliminarily specs on this driver ?

figure it just sets the zero point for the virtual ground? so it should be 1/2 the input voltage... am i right? do I get a gold star?

Can I use 2 diodes in serie\paralell with this driver ?

I dont have google.com acount, can you take PayPal ? :-)


Cheers

Thanks, I made a few changes. The seemingly contradicting statements were referring to two different cases: driver off and driver on. The N2 manual did have 'laser' in it, but not in the first paragraph, so that's been changed.

Close, you got the right concept. Basically it's a power supply CMRR adjustment.
