PPAS (PPAv1 with SMD) board Group Buy

It's basically a PPAv1 type topology using SMD parts and newer buffers that will be fitted onto a board small enough to fit into a mint tin. It will only be recommended for experienced builders, but anyone could potentially make it.

I'm hoping to get a group buy started on these boards. I've ordered a prototype, so if that goes well, then we will commence production of the boards. I'm not quite sure how much it will cost, but maybe ($5)? if enough people are interested. So if that is the actual cost, please let me know if you're interested and how many boards you would be interested in purchasing.

THese are projected board orders, although no one really knows for sure unless the costs are finalized

shipping costs in the 50 states
USPS Priority Mail: 4.50 for any size order (need to charge a bit extra to cover bubble wrap), and this is the only shipping available, as it makes my life easier as priority mail is simply superior in every way to any other shipping in terms of speed and price

USPS first class will be available to people who live in the Bay Area, as it still will arrive in only 1 day (express mail speed)

GROUP BUY CLOSES WEDNESDAY, JUNE 7 5:00 PM PST, AT WHICH TIME I WILL BE SENDING OUT INVOICES. PLEASE EMAIL ME YOUR PAYPAL ADDRESSES NOW TO DANIELHPAIK@GMAIL.COMAND HEAD-FI USERNAME, AS WELL AS THE NUMBER OF BOARDS YOU WANT. ALSO, SPECIFY CREDIT CARD OR PAYPAL BALANCE

I withdraw my order for now....sorry.
I'm not that experienced DIY'er, and from ATAT's test build I can tell, that any problems like those he encountered would make me go crazy.
I probably need a more matured design - think I'll go for ordinary Pimeta or PPA instead.

Board artwork

Board art has been finalized.

There should be absolutely no problems with this board. This has all the fixes I made to the original prototype board...
I'll have bill of materials and such up soon.. hosted courtsy of [AK]Zip

For those who want low current draw, you can grab BUF634Us from ebay for $5 each... these are confirmed working. LM6321s are not yet.. I'll do that next.

Oh this project requires some tweezers .. the SOT-23 is hard to solder... but you shouldn't have any problems if you can build it..
