Hey Moh...

Are you also planning to sell Driver Kits... Just the board
and unmounted parts for the members that might want
to roll their own...:thinking:




Welcome to my world....;)

probably. makes it easier on me.

Yes, I would like that too. Just throw the components in a bag and I will figured it out.

No need to figure anything out. The parts should be identified
on the PCB and the schematic tells you which part is
which..

@Moh...
Yeah... that's what I thought...

Though you might need a magnifying glass to read the resistor values! (if they're even indicated on such low resistance SMD components).

Alright, so I forked the design again, essentially just to make it easier to heatsink. I'm forking from the OVP board though, because I *really* don't care about OVP. With a $30 Flex, I can see wanting to make sure your board survives if a diode somehow dies and goes open-circuit. But at <$5 to put these together, if a diode dies and the circuit goes open and then kills the driver, I'll care about the diode death a lot more than the $5 driver death ;) And in building, I'm really not likely to power them up without a diode attached via soldered leads.

So, I wanted to ease the heatsinking, and thus wanted to move the heat producing components to the board edges. I stuck with 1206 caps so that they'd be thinner. I retained the two-set-resistor approach.

I think they're going to be around $12.

Excellent news. The price is very reasonable for those of us who can't solder SMDs to save our lives. Now I can finally use that saik kit I bought from you ages ago. I've been trying to figure out how to power one of your 1.8A mohgasm drivers with someting that'd fit in it. Two of these set to ~900ma and the extra 26650 (or was it a 26600?) should do the job nicely. Its massive heatsink should be plenty big for both the diode and drivers.

Yep, me too, I've got a Saik inbound from DX. Get some of those Saik heatsinks ready to go on your site, Moh! *ahem* :D

Haha Can you imagine the poor guy getting transported to the ER, and Moh busting out some heatsinks in the back while the ambulance zig zags through traffic?! :crackup:

Hey everyone. So today I have a physics lab (I'm a physics/math double major) on AC circuits, meaning that I get to work with an O-scope. The good part about this is that I can bring in my own rendering of this circuit and test it out there in some spare time!

My circuit is nearly identical to the one that they did except I am using a 6.8uH inductor (only large enough inductor I have on hand and it works well enough) and I changed the layout so it fits on a single-sided 16.2mm round PCB. Anyway, I'm bringing my test load and I will use the PSU there, and all should go swimmingly!

Famous last words! Lol!

Good luck and let us know how it turns out.

P.S. Your degree is very similar to mine! Engineering Physics with a minor in Math - funny thing is that I hated math in high school, but differential equations and calculus were fascinating! I've forgotten nearly all of the math now... :yabbem:

Will do. Hopefully there isn't much ripple - no one likes a rippling circuit!
