Some components for 8 separate builds arrived today - but i’m still waiting on the other half of the stuff, aliexpress had a better offer. Though of course all the chips come from Mouser.
If you wonder about the package where i get only 10 THT resistors: those are 0.1% of an exotic value so it made no sense to stock up. For everything cheap, i grab 100 even if i need 2
Duophonic Midi thing with fun features planned.
Not sure the humble nano will push the performances i want so i might end up jury rigging a beefier board
For some reason the engineers added more tooling holes than i had designed?? They’re the little non plated holes at the side used for the pick and place machine to hold the board in place. Gonna have to ask jlc what’s up with that
Just had a live chat with someone from JLC, they said my holes were ok, it was a mistake on their end, and recommended confirming production files on bigger orders than prototypes. (Pretty benign issue, i assembled a board and it works, so I didn’t care to haggle for compensation.)
Synthcubes always got dem killer promo codes during holidays I take advantage of for pcbs, vactrols(whenever they in stock) etc
Good ole ‘Merican company
I went there for a build night because Wellesley Symphony was off that Wednesday. Great people, got my RYO and/nand done, and played a bit with my 64hp little bitty crazy machine. Try logic at audio rates. Much fun.
I never used Aliexpress but I recently gave it a try. I just got these for next to nothing. Very impressed by the neat packaging given that they were “free postage” items.
What are these? I never dared to order chips there but I regularly order mechanical parts… sometimes it’s the only place where I can find parts at all or not excessively overpriced. (Latest example are the eight-way switches used in the Turing machine)
Edit: Thonk has those switches in stock again, but hadn’t when I was trying to source them
Just stocking on IC sockets. I’ve had a fair share of fake/non-working ICs from online sellers, so I prefer to source ICs locally these days. I will order again generic non critical stuff though!
Just my own experience, I have never had any problems with ICs from Mouser, Digi-Key, Tayda, CabinTech, or SynthCube. (Or AliExpress, but I’ve only ever ordered ICs from AE once and I’ve never really gotten around to using them intensively.)
The card was in the pack of the #1222 VCO. I think the person who packed and maybe assembled it put it in there. Going by the initials “SB”, hist first name could be Sam.
I gave the module a test. superbly tuned. I made one intersting discovery. on the three Kosmo sized modules (of the same type) i assembled i set the limiting cilp of the rotary switch (octave) worng. mine only have three positions…
Somewhat of a bittersweet “mail day.” My uncle, who was a career electrical engineer who did PCB designs for arena sized display installations, passed away last year. My aunt is relocating and wanted me to take possession of his test lab equipment.
My weekend projects beyond module completion is to first get this stack wired up:
Quite excited to have an in place PSU, signal generator, and scope by the workbench. That should allow me to start to tackle the following, a near mystery SSM2044 filter that I got as a throw in from a synthcube order:
There’s only one slice of the internet way back machine that has any pictures of the module, but with no BOM and a completely different set of pinouts for the panel:
Plan is to use a breadboard and that image to try to work backwards, would have been much harder without the addition of the test equipment. I’m hoping it’s close to this circuit and values: http://modular.fonik.de/pdf/SSM2044small.pdf
