| ysionneau | lekernel: do you think it's a good process to ask the manufacturing company to give quotation for fixing the layout file + 1 to 10 boards? | 21:04 |
|---|---|---|
| ysionneau | so that we have the price for 1 2 3 ... 10 boards? | 21:04 |
| ysionneau | or will I sound ridiculous? | 21:04 |
| ysionneau | btw I agree about the possibility to use Mixxeo for those who don't want Flickernoise | 21:05 |
| ysionneau | I plan on doing a doodle and let people choose between the two | 21:05 |
| davidc__ | BTW - what exactly is wrong with the layout/altium files? | 21:30 |
| lekernel | it's probably bothersome to prepare 10 quotes... | 21:31 |
| davidc__ | get them to quote you as setup+per/unit | 21:34 |
| wpwrak | davidc__: the reset circuit is wrong. there are two main changes: one replaces a dodgy diode with a logic gate. the other replaces the reset chip with one that triggers at a higher voltage (and connects it to a different rail) | 21:35 |
| davidc__ | wpwrak: I mean, thats a 5 minute fix in altium, out of curiosity, why get the MFG company to fix it? | 21:35 |
| wpwrak | (regarding the need for a layout change) i'm not sure you really need to fix the diode. the reset chip can also be reworked: http://downloads.qi-hardware.com/people/werner/m1/nor/d8/u24-to-5V.jpg | 21:37 |
| lekernel | davidc__, the way the M1 design was done is schematics in Altium, then routing in PADS | 21:38 |
| wpwrak | (there's a little PCB under the new chip that isolates the 3rd pin from the rail it previously connected to and attaches with the yellow wire to the proper rail) | 21:38 |
| davidc__ | lekernel: ah, yuck. | 21:38 |
| lekernel | then the PADS layout was exported to correct Gerber files for production, and broken Altium files for pretending it was an Altium project | 21:38 |
| wpwrak | ;-)) | 21:39 |
| wpwrak | that's what you get for relying on proprietary tools - effortless instant fragmentation :) | 21:39 |
| lekernel | I don't have the PADS files, and Wolfgang ignored my emails asking for them | 21:39 |
| davidc__ | lekernel: the Altium gerber editor could probably be used to make the changes | 21:39 |
| davidc__ | lekernel: editing gerbers = yuck, but eh. | 21:39 |
| lekernel | I didn't know of this PADS step before I tried to use the Altium files, and Creotech told me they looked like a botched PADS conversion | 21:39 |
| lekernel | and after checking - the Gerber files had comments that said they were generated by PADS ... | 21:40 |
| ysionneau | 22:34 < davidc__> get them to quote you as setup+per/unit < so you take for granted that the unit price would not change between 1 and 10 boards? | 21:43 |
| Action: ysionneau have no clue about that | 21:43 | |
| davidc__ | ysionneau: low volumes like that the cost is typically dominated by the setup cost | 21:44 |
| ysionneau | ok | 21:46 |
| davidc__ | ysionneau: depends on the mfg. I mean, just tell the MFG you want the quote broken down that way and why and they'll tell you if you're making a wrong assumption :P | 21:46 |
| davidc__ | are the unpatched gerbers + the broken altium project somewhere? | 21:56 |
| lekernel | http://milkymist.org/mmone/rc3_design.tar.bz2 | 21:58 |
| lekernel | http://milkymist.org/mmone/rc3_gerber.tar.bz2 | 21:58 |
| lekernel | and r4 (never manufactured, but used as base for mixxeo): http://downloads.qi-hardware.com/hardware/milkymist_one/sch/20120710/ | 22:00 |
| ysionneau | gn8! | 22:13 |
| mumptai | lekernel, why was routing done in PADS? | 22:39 |
| lekernel | I don't know, email Wolfgang | 22:40 |
| lekernel | reply not guaranteed | 22:40 |
| mumptai | k | 22:40 |
| lekernel | let me know if you get an answer, I'm asking myself the same question | 22:41 |
| lekernel | that and why I had never heard of this PADS thing before attempting to use the Altium files | 22:42 |
| mumptai | actually mm1 doesn't look too complex for altium | 22:42 |
| mumptai | did that kicad design work out? | 22:46 |
