For those of you who prefer Mouser for parts sourcing, I’ve created a few projects to share:
Shruthi-1 Digital Control Board <-no screws/washers, and I’m constantly switching around display and LED colors…
Digital Filter/FX Board <- not including chips available in Mutable shop. Power connector needs modifying, see below posts
4-Pole Mission Board <— No SSM2164 quad VCA
Dual SVF Board <-cannot personnaly vouch for it, compiled by MicMicMan
edit: DSP board built and works great. The Control Board BOM, half of the Polivoks (got the partial kit), 4PM and Anushri are still untested. USE AT OWN RISK.
Oops! Thanks, randy. Fixed.
Polivoks partial BOM tested and passed. Thanks, Olivier!
Next up: Digital Filter/FX board…. then when I fall in love with that, I’ll have to build it its own controller board….
The “Red Alert” kit was a limited run in the shop that included the crazy Soviet-style case, red PCBs and most, but not all, of the parts needed to build an entire Shruthi-1. The remaining parts are on the Mouser project linked above.

OK, here’s one: the digital filter/fx board has smaller holes for the power jack! Don’t use the one I listed! It would work on the polivoks, though.
I couldn’t seem to find an appropriate DC power jack like this at Mouser at all. I ended up cutting the pins and just soldering some old resistor legs to the remaining pads and that worked just fine.
In the meantime, I’ve changed the above linked Polivoks BOM for all the parts for the entire filter board only, since I bet everyone who bought a limited partial kit has already built them.
yes, the only purpose is to have both boards in red and with similar graphics.
Looks like the hex spacers are back ordered, doh!
Yeah and if you’re going for the red Soviet case stylee, be sure to get these red LEDs and this red LCD display instead of the yellow/amber ones I listed. RED ALERT!
Oh and here are the switch caps (I think black looks best against the red case). And people say these are the spacer headers to get.
You can get the hex spacers most places. I got a few on ebay from a seller pic-projects:

Indeed. I was just bummed cuz it cuz down on the project’s one-clickabillity. I’m sure Mouser’s probably got a bunch of other kinds of hex spacers, I just haven’t got the time to check ATM!
Just checked. Yeah, looks like Mouser is clean out until April 13 so not too long of a wait.
Just realizing I didn’t include screws and washers in my BOM... !!!
Yes, everything needed to build the polivoks filter board is on that list. Except, of course, the PCB itself, available here .
In case this hasn’t been posted yet, Mouser is now carrying some Arduino parts, specifically the 6/8 pin stacking headers. The part number is: 782-A000040. They come in a pack of four headers, two 8-pin and two 6-pin.
Nice! Added to my Control Board BOM!
I order for more than 100USD/100€ from Mouser and Digi-Key from time to time. I think that customs and VAT are included in their prices. No extra shipping over those amounts. Experiment with switching between USD and Eur and use xe.com to get the corresponding exchange rate so you don’t get shafted.
It’s possible that VAT was extra, but I sent my packages to work at a very large company that also orders stuff from them, so they’ve slipped any extra bills under the radar or something…
So: I recommend collecting more things you might need in order to get over those minimum sums for free shipping.
Digi-Key ships uber-fast to Sweden, Mouser takes approx 3-4 days (standard delivery)
Oh, and make sure to set your country to Finland instead of the US so that you get the EU prices with customs and things right away. You can freely switch your currency back and forth while adding to your cart. Those sites will catch that you’re not shipping to the US in the end when you check out, but then you could be in for a strange surprise about the total cost, so stick to using your own country :)
The bad thing isn’t the Customs Fee . . . in Europe its usual between 0 and 5% of the Estimated Value for Electronic Parts. You will have to Pay your local VAT for the Estimated Value that is something between 19% and 22% on top of that.
The clever tricky Chinese always declare a Value of 42€, no matter how much it is in reality. Maybe they try this also on Euro Palettes…..
Possibly some mistakes, and I haven’t found a pin header to really match. Anyway feel free to check and correct this
Mouser BOM for the Dual SVF board
Please note that the V2164 chips are missing – you still have to find them somewhere else like small bear electronics.
Those headers are OK, you just have to snip 2 pins/slots off to make it a 6’er for the digital RX.
Also, your power connector won’t fit. The lugs will be too large and you’ll have to rig it up. See my earlier post about my experience with that and the digital fx board. :D
Oh, ok. Sorry I didn’t notice your post.
As for the power connectors, I’ve got some of them as a “personnal back supply” so I won’t order them, but I’ll change it in the linked BOM for other users.
Those pots fit in the case just fine, feel identical to the custom OEM Mutable Instruments pots and just require a single snip of the plastic shaft to shorten them for the knobs. Pretty sure no other pots at Mouser are a better choice for the Shruthi-1. There are some Bourns pots that I tried: they’re very loose, feel junky, thumbs down, do not buy em!
ok. I’m putting a polivoks together right now and the Mouser Polivoks BOM lists 4 * 47k resistors but the board requires 5. Also, there is an extra 33k resistor. You may want to add one of each as the distortion mod requires switching 2 * 47k for 2 * 33k resistors. 12 cents isn’t going to hurt anyone :) Also the encoder shaft is a little short for my liking 652-PEC12-4217FS0024. You may want to replace it with the next length up 652-PEC12-4220FS0024 to match the length of the pots better. thanks.
anybody found a Power supply for the ambika yet, from Mouser, Reichelt, etc ??
if possible, i dont want to pay shipping for just one power supply, when i have to order the one olivier linked in the wiki
i found one from mouser that looks ok, but has 3 weeks ordering time :(
9V DC, won’t work. Ambika does not need a traditional wallwart (AC to DC), it needs a simple step-down transformer to 9V AC. This is a bit harder to find as there isn’t a lot of stuff which is AC powered…
