I received an Email from someone today that made me realize I have not updated the Blog with what is going on right now.. Sorry, guess I have been too busy Email back and forth with a small group of about 10 people, so for anyone else, this is what is cooking:
- About a month ago I posted onto several Email lists about this regulator, and asked if perhaps there was some interest in getting together a group build.
- There was.
- Right now, 20x sets of Rev 0.1.3 PCBs have been fabed and are having the SMT parts mounted.
- 10x of those PCBs will continue to have all the through-hole parts soldered in.
- All are being done in China (http://smart-prototyping.com/) so no more hand-soldering for me!
I expect to received the assembled (and partially assembled) boards in a couple of weeks. At which time I will flash in the firmware, spray them with conformal coating, and send them off to the group of folks. Along with USB programming adapters, mounting hardware, and a heat-sink. People will need to drill out the heat-sink, bolt it together, source their own Amp Shunt and Temp probes and do the installs. But hey, we got a thing going!
And if anyone is interested in one of the partly assembled PCBs, drop me a note. The bare PCB costs around $9, plus about $7 for the small SMT parts that are getting professionally re-flow soldered on. Finished cost (after purchasing the remaining parts at say Mouser) will add perhaps another $60 or so, but you will have to hand solder those parts.. Then around another $20 for the heat-sink, screws, USB cable, etc..
OK, there is an update of the one or two readers of this blog :-)
