Re: Super Sixteen build support thread

I'm finding that the black panels seem to have a very slightly larger cutout for the 3mm LEDs. Aha, that would do it - I'm using one of the metal panels. Otherwise everything came together really well - it was a really well-written and detailed guide! Two other very minor things: on section 2.2, st...

Re: Super Sixteen build support thread

So I was following the build guide, which seems to agree with the video, when I got to the LEDs. I followed the directions in the written guide about putting the hex nuts on the top & bottom potentiometer, left and right CV jacks, and the screw into the standoff, and then put tape over the LED holes...

Works great!

Just received mine a few days ago. It was about 23 days from shipping in Russia to arriving at my office in Canada, but that was pretty much what I was expecting. It was a straightforward build - well-labelled PCB, components were pre-sorted and labelled as well. I didn't even need to check the buil...

My kit (via Thonk) arrived earlier this week and I was excited to have time to build it this weekend. The build went smoothly - took me just shy of 2 hours from sitting down and opening up the build docs to having it installed in the rack and doing some listening tests. Great documentation, nicely p...

Just finished building my RYO Penta, seems to work great. Thonk had the PCB+panel+pots but was out of the full kits, so I built this from parts scrounged from my parts bins. I had compatible-ish parts on hand for everything except the 2N7000s, which I was able to pick up at a local shop. Had to make...

Just finished building my CV Express today. Sourced the PCBs & panel from SynthCube. I wound up purchasing the 1/4" jack from Thonk because I was having a difficult time finding the correct jack in stock anywhere, and I hacked in a panel-mount SPDT switch (instead of PCB-mount) for the same reason. ...

I've known that Dasz was working on this for a few years, but there was a lot of mystery around it.

Hey neutron7, looking at the retail version of the NOA, it looks like there's been 4 new CV inputs added (A, B, C and mod) and 1 new button (Pulsar). From a technical standpoint, how difficult would it be to add those on a small secondary panel to the DIY version of the NOA? Is it as simple as just ...

I did the same thing.. The building instructions said nothing about this. I too assumed that the button that was packaged alone was supposed to be underneath the teensy. I have a desolering vacuum pen, might I use that to remove both of the buttons or is it too late to remove the one under the teen...

A regular 0805 1k resistor will work just fine as a substitute. Phew! I received my kit from Synthcube (PCB v1.2) and it came with an 0402 PTC thermistor (a Murata PRF15BD102RB6RC from Mouser). It was going to be a definite challenge to solder that one - and I had thought that the 0805 caps were ba...

Is there an easy way to change the offset to be +/- something less than 5 octaves?

I probably should've at least sketched out that part of the circuit before putting it in my rac...

Good question, Brad. I just finished one a few weeks ago so I'll try to check mine sometime this week for you. I was really happy with the build and the module turned out great, though I'm just getting started using it. I assume by "quieter" you mean that it's outputting a lower voltage (in absolute...

No worries! 8-) My current problem is much thornier. You know in the build guide where it says "SW8 is the latching button which mounts on the opposite side of the board to the Teensy. It has to be mounted now, otherwise it becomes very difficult to solder after the headers are soldered."? Yeaaaah, ...

Nice, good to see an expression pedal module kit becoming available!

I have something similar on my DIY list in the next few months so I can get some use out of my Roland EV-5, but I might just wait and order your kit from Thonk instead of doing a full DIY myself.

Maybe Neutron can correct me if I'm wrong on these, but I may have answered my own questions, at least to a point. Based on Harry Bissel's capacitor FAQ - http://www.muzique.com/cap_faq.htm - I think that it should be safe to use a 3.3nF mylar cap in place of the MLCC C0G as specified in the BOM. I'...

Might be a confusion in kitting the SynthCube. In my kit the 3.3nF is large and square, fitting the C20 footprint. The 15nF is blue and quite small. Not sure what technology that is. Right now I have the blue 15 nF at C20 (legs stretched) and a 3.3nF ceramic I had on hand at C18, as the supplied pa...
