Quick question #25

Open thedaniel opened 3 years ago

thedaniel commented 3 years ago

Sorry, I looked around online for a twitter handle or email, and didn't find something right away so I figured I'd open an issue. I have a need for something like your project to prototype a sampler module (since i apparently fried my 1010 euroshield) and since you mention you're coming along with v2, I just wanted to check if you think I should wait for you to verify your v2 circuit, or build the one that's described in the repo today. This is in no way meant to be pressure on you to provide a date or to hurry you, just curious if I'll be happy with v1 for prototyping if I start getting PCBs and components ordered or if you reckon it's worth the wait for v2. You can reply here if you like or drop me a line at danielwh@gmail.com - or ignore and keep working on your own time :)

hi. v2 is almost done. although i’ve been saying that for a while. i’m pretty sure this model is good, i’ve fixed the last outstanding issue, hopefully i haven’t created any new issues. latest breakout board arrives on monday so i should be able to assemble it and test the vitals by end of next week. probably worthwhile to wait a week. if you like you can order the pcb in the meantime. pcbs are cheap enough. the best thing is to learn to reuse the ics then your only cost is pcb and they’re very cheap from jlcpcb

get started with parts. let me know if you have a hard time sourcing any parts....

thedaniel commented 3 years ago

Perfect - this weekend I want to make up a bunch of BOMs on Mouser for my various oustanding projects and make one big order, and I will start one for this as well.

thedaniel commented 3 years ago

Is there a handy text / spreadsheet BOM or should I just go through the schematic?

newdigate commented 3 years ago

i use interactiveBOM and i generate it every time i push my commit to github. in github actions under the repo their should be 2 sets of builds, o e for mainboard and one for breakout board. go to the latest build and download the artifacts. inside the strifacr you will find the interactive BOM html file.

newdigate commented 3 years ago

having said that, there might be generic part descriptions. let me know if you need any specifics.

thedaniel commented 3 years ago

I think without repo permissions I can't see or download build artifacts, unless I just can't find it in the UI (or maybe it's API-only)

newdigate commented 3 years ago

Ah, I didnt realize that... always thought everybody could access those. You could fork the repo, then your artifacts would be available under your folked repo..I couldn't seem to make the artifacts public on github for some reason.

I have created this release as a work around in the meantime: https://github.com/newdigate/teensy-eurorack/releases/tag/v2.0-beta - it should have the interactive BOMs for each board.

Also there is a message on patreon about the bypass caps being slightly too long. 10mm bypass caps (the aluminium through hole ones, 8 in total, need to be slightly shorter than 10mm so that mechanical collisions don't occur between the two boards)

thedaniel commented 3 years ago

nice thanks! i think i might be able to get the build artifacts via the API since it's a public repo but this is much easier, thanks

RE: front panel - its not on the BOM... There is an .fpd file in the repo which you can submit online to schaeffer-ag (as I assume you are in europe - there is a different company in US) and they will send. You can load, submit order using their front panel designer software, https://www.schaeffer-ag.de/en/front-panel-designer

You can also CNC into 2mm aluminium or 2.5mm perspex if you like gcode.

Or you can order aluminium pcb from JLCPCB, I havent tried this yet, Im hoping its cheaper than shaeffer-ag (usually about 33 euros or so per faceplate from shaeffer)
