Well, way back at the beginning of this work log I started on the Power supply solution and blew the supply in the course of events.
I ordered another one and they sent me the wrong supply... I called them... they sent me the wrong supply again ... with an RMA for the first wrong one. YEESH!
So I ordered what looked like an identical supply (by Rhycom)... The general layout is the same... but the board is indeed a little different.
Two shots of the Rhycom supply with the cover off...
Here's a photo comparison of the labels and casing covers... looks like the same actual manufacturer to me.
After desoldering the Regulator ICs... the first heat sink appears to be almost identical to the one I made for the PowerTek supply... so no modification needed here...
The second one's holes were a little different on two of the ICs... so they would mount like this unless I move the holes over...
So... that's what I did ... I moved the two holes over 1/4" and tapped them... also... the holes for the mounting screws that go through the board are completely wrong now. I had to drill and tap those as well.
Ultimately this means that my original solution will work... but it will not look as good with all the extra holes in it. I may end up doing a new design down the road, but for now... it's okay.
More to come tomorrow... CHEERS!
