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.

Thanks Bruce!

I loaded Bruce's latest design to BatchPCB.com. Here is the link, (at cost) at $11.50 each http://batchpcb.com/index.php/Products/53019

I will probably get to an order in a week or three. If anyone else wants to give it a go, feel free. Bruce's board and the UBW32 board are about the same area, so the cost for an order of 30 should be pretty close. Might be closer to $7.00 each for Bruce's board, where the UBW32 would be $6.50.

Please chime in. I would like to see if people are still interested, and if so, which board.

Or, I could just put both boards on batchpcb, and those interersted could place their orders.

Let me know.

Thanks,

Walter

Maybe folks have lost interest in this. Bruce's board can be purchased in singles from batchpcb here . Only bad part, is they charge a $10.00 handling charge for each order. Not too bad if you find some other boards in there that you like. I tried uploading the UBW32 to batchpcb, and that board fails their 8 mill spacing requirement. Kind of makes you wonder where they have this one made! And things are tight enough on that board, that I doubt it could be made to pass batchpcb. (slightly lower quality PCB production I guess). So for either board, cheaper alternatives would only be available with a group buy. But then again, you kind of need a group for a group buy.

I have not lost interest, just have not had the time to worry about it.

I guess I could send you the money for four boards if that will help with an order, I sent four chips to Bruce so I am still in it, should do something with the parts.

Let me know.

[cncmachineguy]

Walter, How many more do you need for a "group"? This looks intresting to me. Not sure what I need it for, but when do I ever know that - LOL

[ScaleRobotics]

Thanks guys, just didn't want to have all 30 for myself . If you two are interested, chances are a few more will be later. I'll put in an order this week.

Walter

[mackrackit]

Which ones are you getting? Does not matter to me, just curious.

[ScaleRobotics]

Only because I like the way it fits on my breadboard, I chose the UBW32.


Bruce's board is available on the BatchPCB site

[mackrackit]

Does the UBW32 takes the same chip as Bruce's board? And what will the cost be per board? I think you said but I do not know for sure.

Thanks for Asking Dave! I stupidly thought they were the same package. The UBW32 uses the 100 pin package, Bruce's design (and the CUI32) use the 64 pin PIC32MX440F512H chip. Let me do an about face ... Will order up one of Bruce's boards from BatchPCB and build it up. When all works as planned will place a larger order.

Thanks for catching me.

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.

After reading a little more about this, Put me down for sure. I have no problem with 4 or 5. As I think about this, I may even have some uses in mind. Thanks to all who have put so much work into this!!

[Ioannis]

OK, I am still in.

What size parts wll be used?

I am getting old I guess and my eyes do not focus very close

Ioannis

Yeah, I am having the same trouble. Might have to up my reading glasses magnification.....

But the toaster makes it a lot easier. We are back to a 64 pin PIC32MX440F512H, if that makes it any better.

Also looks like dhouston found a cheaper source for the boards, so once I get a single running, I'll try them out for a larger order.

Does this head mounted gadget give a good stereoscopic view?

I use a similar magnifier when working with SMD's (components to 0402 and pin pitch to 0.65mm). They do give good depth perception - if that is what you mean by stereoscopic view.

[Ioannis]

Thanks for the reply. Yes that was what I meant.

Ok, it took about three weeks, but I just received my order from batchpcb / Sparkfun. The board looks pretty good! Thanks again Bruce! I still need to get a few parts to put it together though. Once it works, I will place an order for at least 40. Sounds like dhouston found a pretty good deal from ezpcb, so I'll probably give them a try. Here's a picture of the board. The good thing about this order (not sure if this was just a fluke) was I got two of all 3 boards I ordered, but I only paid for 1 each of the three.... Anyone else tried them before?

Edit: One out of the six boards I received has some problems. It just happens to be on one of the StickOS boards. The trace E1 on the back side of the board wasn't fully etched, and in at least two places, this trace goes to ground. The other boards don't show signs of this problem. Probably just another fluke..... Anyway, here is a picture of the pretty side.....



And ugly side....



Well, at least they gave me one free one, I guess I can't complain. And after a little work with an exacto knife, they both should work.

[Ioannis]

Thats great! Despite the little shorts. A knife would make the job OK.

Looking forward for the working board

Google "bausch lomb magna visor"... around $30 USD on Amazon.

You will not be dissapointed! I use mine with my regular perscription eye glasses on.
Like a breath of fresh air when you need the detail.

I highly recomend them for electronic work.

[rmteo]

Any impressions of StickOS and/or PIC32?

> But I don't think StickOS is available yet for MX795.

It is now. :-)
