Just finished my first 1.2A build sunday night. After reading about the heft of the 445 diodes, I decided I wanted to crank it up, but I ran into some problems getting > 1.2A out of a single flexdrive: http://laserpointerforums.com/f67/micro-flexdrive-jumpers-64734.html
Long story short, wired two in parallel, one thermal glued under the pill, one on top. The one on the underside was set to 900ma, and the one on top 700ma.
The result? 1.63A measured inline with the running diode. I'm pretty stoked, but still confused as to why I couldn't get a single flexdrive to do this for me.
Here are pics of the build: Index of /dont_lase_me
The pics of the dual flex drive setup start at 0640. op:
PS. For anybody trying to remove a component glued with Arctic Alumina, put it in the freezer for a bit. It only took about 10 mins in an anti-static bag on top a bag of ice.
Similarly, when waiting for it to harden, put it under a hot light. It only took about 15 minutes to get a handleable bond.
