A group buy of PCB's might be economical since you can amortize the setup fee over the qty of boards. BatchPCB also has a marketplace option where others can purchase my design which would be shown on their website. I would add zero markup, but they might (not sure).
Let me look into that.

I have asked PCBCART for a quote for 10 pcs - result is $104 not including postage. I'm thinking of ordering 10 - might be a better job than me making my own (no plated thru holes) so if anyone wants one, let me know. If we can get up to 10 or more, its a go. You would need to send me about $11 plus postage per board.

Count me in. Where do you want us to send the cash?

Me too please. I am about done with my controller (Thanks to Paul for the boards and help finding parts). Just got my motor connected to the transaxle so it may take a while before I get to this, but it looks awesome. Great work!

Well, that's 4 so far, including me. Sounds like enough interest to place an order. I have a PayPal account somewhere, probably you can pay that, but I'll wait until they give me an exact price (from the Gerber files) and also the postage then let you know.
Also waiting to hear back from Chris to see if the pcb outfit he used will sell us boards and at what price - I won't place the order until we hear.

Hey guys,
Even if I apply no markup on the board selling thru BatchPCB marketplace, your looking at no cheaper than what I paid. $10 setup plus $2.50/sq inch.
That came to $22 excluding shipping. That was another $15. Order qty is 1 so you can't amortize the $10 setup over multiple boards. You'd need to place multiple orders! Worse is the 5 week leadtime.

PCBCART is also overseas, but I don't know their quoted leadtime.
Their pricing, however looks like the best I've seen.

Harlequin2, thanks for organizing this

[jackbauer]

I'm in for 2 or 3 pieces.

[Weisheimer]

I would also be in for 3.

We should also look at building a public BOM at Digikey or etc for the parts
and then posting that link.
I'll look into that if I can put aside a bit of time one evening.

Thank You Chris for sharing this project!

PCBCart leadtime is either 8 days or 12 days (12 is cheaper). And they are never late (except during the chinese new year). Also, their shipping is SUPER fast, around 2-3 days to the U.S.

I'm in for one. My car is still a bit from completion so 5 or 6 weeks for the board is not an issue. My only concern is cable length. I have an old beetle so the controller will be in the rear and the display on the dash would require an extra log RS232 cable. Would there be any other way for the two to communicate? Any ideas?

John,
RS232 @ 19.2k baud, should be good up to 25ft. Use good shielded cable and you'll be fine. Use a low capacitance shielded cable and you could extend that to several 100ft.
