If I had the money I'd be all over that BR. :'( Hope it sells quick, I can't take the temptation much longer.

Thanks guys! So far there has been significant interest in all lasers, but it's not over yet!

Two more items for sale: assembly 'seconds' modulatable lab laser driver boards. These are professional pre-assembled modulatable laser drivers capable of up to 5A of modulation. They work well for driving blu-ray, long die open can, and DPSS green and blue lasers. They are 'seconds' because the board corner was burned a little during assembly, but are tested and perform just as well as the firsts. $25 each.

mmmmmm must resist!

i already ordered so many of your new flexdrives... that looks like a very nice driver tho. the huge black thing on the right is a pot correct?

looks like an excellent driver for a lab style or project box laser ... would be so nice to use for a Spirograph!

The huge black thing on the right is a power transistor, it's what makes it capable of controlling up to 5A of current. The pots are the white boxes and black box with silver circle.

Phat specs.

Would it be suitable for indefinite running of a PHR-803T labby? At say, 150-180mA? Around that area? Would I need an additional heatsink for it (the driver)? (And if so, you got one you could bolt on? )

If that's a yes for all those questions, put me down for one

Yes, it could drive a PHR labby indefinitely with only the included heatsink. The bolt is included
What you choose to drive the PHR at is your shoice, but when making a labby, do consider the lifetime of the diode when run continuously.

What kind of voltage output does it do? What kind of voltage would I need to drive the driver at to run a PHR off it? What kind of mA input would it need as input as well?

I'll probably run it a little lower, around 120-140mA. Somewhere around there, so I can get a constant output. I'll have a look and see what other people are running them at in continuous ways

For the PHR, you should power the driver with 6.5-9VDC. For the current input, you would need to give it 40mA more than you drive the laser with, that should be plenty safe.
