Re: New run of orbshields

VDX: I'll see what I can do... not sure I can come up with a good way to package everything nicely, but I'll think about it. You'd have to flash the chip yourself, though. Kenyee: Actually as it turns out the footprint I used didn't have solder mask, so I can't blame the PCB folks. But this was the ...

Re: New run of orbshields

Had a little time this AM to try and repair the SMD boards. I'm having a real problem with the USB connectors; they're hard to align, and VERY hard to repair if something goes wrong. So far my success rate with the 3 prototype SMD boards is 3/3 for programming the ATMega, but only 1/3 for plugging i...

Re: New run of orbshields

Irritatingly, the pitch between the pins on the QFP package was fine enough there wasn't any solder mask there! However, when I was able to put the chips down straight, I didn't get many bridges; when my hand slipped and smeared the paste, I got them. I'm going to do more work on my "vacuum pen" jig...

Re: New run of orbshields

For now, yes... but this site is really more about the orb itself and it would be rude to coopt it, so I am setting up a webstore and forums for the "Orbotron" itself (silly name for the new device). It's not really a shield any more but its own built-in Arduino-compatible board so that the final SM...

Re: New run of orbshields

OK, 9 kits made with 2 accounted for going to testers. The three prototype SMD boards... not so successful. I didn't have quite enough parts so only one is fully populated and while it accepted programming OK, it's not functioning and I probably can't test more while my guest is here (bless her hear...

Re: New run of orbshields

Jim: Ha, hadn't meant for the store to really be active yet--it's still in a trial mode! ;) You'll get a kit sent out hopefully tomorrow... with my guest in town I haven't had time to assemble things although she'd probably find it funny. The kits are in and the first 3 SMD prototypes are in, so tom...

Re: New run of orbshields

Okay, brain is full for a week or so. I have more SMD parts on order and sent off for a batch of SMD boards, more stencils, and case parts. The 10 through-hole kit boards should be here this week and I think I can get those out for cost to testers. I have three prototype SMD boards coming this week ...

Re: New run of orbshields

[quote="kenyee"]Wayyyyy better than the previous case IMHO. Very compact and svelte[/quote] Well, it's largely your fault, so take some credit; I was pretty complacent with the big fat case :) It might be possible to get it smaller, but I worry it would start getting annoying to build (and I haven't...

New cases designed. Plus bonus chance to learn more about Blender and Inkscape. At least I can do something semiproductive with the delays...

Re: New run of orbshields

I'm about to go postal on delivery services, as it were. Attempted delivery of the boards Thursday and would "automatically attempt a second delivery on the next working day" so I arranged to work at home and sat here until the end of the delivery window... 7:30pm. Nothing, not even a "missed you" c...

Re: New run of orbshields

Well, the total board area is almost (but not quite) 1/4 smaller, and at about $1.6 GBP/square inch (in small batches) x 2.3-2.75 (recommended multiplier), that could be about $4 off the end price, which will still likely be much higher than I'd like it to be (which is why first round will be at cos...

Re: New run of orbshields

Heh heh... okay, yeah, this will be worth the delay. Much nicer even if I only dropped from 4 square inches to 3.25. I've placed the proto order for new PCBs (and now need new stencils, and new cases; this is what you drive me to... ;) ). But seriously, I like this much better, plus I found another ...

Re: New run of orbshields

That was actually the response I got from Adafruit too (it doesn't have to be polarized; they just used it because electrolytics were cheaper at the time but they use ceramic now). Well, learning experience. I may make that change for production, may not; I'm not bothered too much either way to be h...

Re: New run of orbshields

Ugh, never a dull moment ;) Just to show I'm not being a total slacker while I wait for boards, I finished my "manual pick and place gantry" to stabilize the vacuum pen (if it works, I'll show a picture, but I'm too embarassed to show the monstrosity if it's just a waste of time :) ). I also convert...
