StickOS

[jrprogrammer]

I sent 6 chips via Priority Mail. I only need 3 back on the board, so you will have 3 to donate or deduct off the board charge.. StickOS looks real interesting...

OK. I'm closing the offer now so I don't have to build 10K of these. If they get popular down the road we can make & sell them to anyone not already in on the group buy.

I have about 1 more week or so to finish a job, then I'll get busy on these. I have received my 3 samples, some from Dave and Walter.

I tried to upload Bruce's gerber files (from post# 67) to Sparkfun's BatchPCB site, but I received a message saying " Unfortunately, your design "Bruce__s UBW32" violates our design rules of 8 mil traces with 8 mil trace spacing."


I am getting a quote on 30 boards from www.pcb-pool.com for the design v2.6 located here: http://www.schmalzhaus.com/UBW32/doc...easeNotes.html



It looks to be less than $5.00 for each board

Will let you know more when I get an official quote.

Hi Walter,

I sent you some updated Gerbers, but I don't think you received the email so I'm posting them here. Just in case someone else wants to try making a prototype.

Sorry I haven't had time to move on this. We sold our big oven before the move, and our desktop unit went ker-flop shortly afterwards, so I'm not doing much fine pitch assembly.

I increased the spacing, trace widths, etc to 8 mil. Note I haven't made a prototype of this yet, but anyone that wants to is welcome to the files. Guess I better start returning a few chips too. Sorry. If it ain't one thing it's another.

Did the quote look reasonable?

Did the quote look reasonable?

I tried uploading Bruce's newest layout to batchpcb, but still got some "errors" on clearance (allowable clearance for batchpcb). I am not familiar enough with Dip Trace to make the batchpcb required changes to Bruce's board. I had planned on getting one board made through batchpcb, before getting a larger quote.

So at this point, it seems best for me to get the slightly smaller UBW32 board made.

I have a quote from http:www.pcb-pool.com for 30 of the UBW32 boards for $6.50 each. I think this is very reasonable. If there is still enough interest from people wanting to populate their own boards, let me know, and I will start the order. Otherwise it is almost double the cost in singles from batchpcb, plus (I think plus) a $10 fee. So a larger order, is definitely the way to go for costs.

Let me know what you guys think of the UBW32 v. 2.6 circuit board for $6.50 plus shipping. UBW32 Site

You might notice that the v.2.6 board can be populated with two different chips. From the UBW32 website:
Created two board versions, one called MX460 and one called MX795: Only difference is silk screen of board name, otherwise they are identical. But I don't think StickOS is available yet for MX795.

I ran this set of Gerbers through the batchpcb DRC and it passed. Looks like they have 8mil limits on spacing for less than 4 layer boards.

Sorry. Forgot to include the DipTrace file.

Bruce,

I have not followed the thread so am not completely clear on the exact size, minimum trace/space and quantity desired but I got a $96 (includes shipping) online quote from ezPCB for 30 pcs 3.100 x 1.475 with 4 mil trace/space and 8 day delivery. I've used them and they do excellent work.

It is now. :-)
