oh - no 3 of them are different.  You'll see they are bigger.  Here's the part:  Alps RK12L12C0A0E

The bass boost pot is 1k:  Bourns PTV09A-1025F-B102
Rest are 10 k.

Hi,
The spec is:  10k, linear, 6mm diameter, D shape, 25mm height. 
I think Bourns and Alps both make one. 
Possibly worth a bit of contact cleaner first?

You're using an Atmega328P ?  It should work fine for that, but not for any other Atmega.  This is because I have hard-coded the Atmega328P into the AVRDUDE command in the software.
Also, you should have a cap (think 0.1uF) in series with the reset line in your schematic.  Do you have this?

Hmm, well I was actually next to DIN Sync at Superbooth and he has a 101 DIY project that looks amazing! https://youtu.be/wB7yyMU_h24
Ginko have the new sampler slicer module if you're into modular: https://www.youtube.com/watch?v=gl-eEHc66Y8
Not too sure about 8-bit options at the mo.  Most seem to be preassembled.

Yup, red stripe down on everything I make.

Excellent, glad you got it working. Sometimes the computer needs a restart after installing the FTDI drivers for it to work properly.

It worked!  Let me know if you have any other issues.  Will delete in a couple of days if all's working now.

try it now - there was an html tag missing which makes it download rather than display in a page

I would much prefer a simple 7 segment display controlled by a shift register. I could wire up a shift register to a display, but I can't program these, so I guess I will keep trying. thanks

The main issue would be that the a shift register requires 3 data lines, but there's only 2 available for the value LED.  You could make use of pins 0 or 1 if you don't intend on using MIDI.  It would take some careful programming to make sure that the time taken shifting of data to the display didn't halt the playout of the sequencer.
Possibly a simpler alternative would be to put a MIDI connection on the front panel (using mini-jack wiring).  Then control it from an external MIDI controller, or even use the Touch OSC or Lemur templates for a graphical interface.  All parameters are available on MIDI CCs.

Software technical support / Re: Flashing from Linux

Hi - I am really keen to get into using Linux, but I have zero knowledge about it and right now I don't have time (in the middle of developing new synth).  I don't have any Linux machines and even building one seems full of choices (which OS do you use BTW?), let alone working out how to use it!
If I give you the source code for the Easy Uploader, would you be happy to install and run it from Qt?  Qt is free and running it is as simple as opening the project and hitting the green play button. 
cheers, Paul

Hi - just follow the instuctions on the Downloads page! http://soulsbysynths.com/miniatmegatron-downloads/  It's really easy and doesn't take long.  All downloads are on that page (Easy Uploader and the hexs)
Also a tutorial video here: https://youtu.be/07cy_KiLm8k

Will email now.

Fault report / Re: Very loud mains hum from audio out

Hmm hope it isn't the soldering on that socket.  I'll probably have to ship it back to me to fix it if it is, as soldering that joint isn't an easy job.

Couple of things to try before getting to that point:
1)  Pull the cable off of the header.
2)  Scratch a screwdriver on the header pins to make sure there's a good metallic contact and there isn't any dirt or gunk on them.
3)  If you have a small flathead screwdriver, push it into the little long thin gaps on the white header socket. https://spellfoundry.com/wp/wp-content/uploads/2013/04/Crimped-plug-500.jpg This releases the metal clips so the white plastic part of the socket comes off.  Look at the 2 pins, are they bent flat? If yes, try and reshape it so it looks like this: http://www.newark.com/productimages/standard/en_US/4812344.jpg 
4)  Then reassemble and reattach cable.
Another option could be for me to post another blue cable to you. It's fairly easy to replace, you just need pliers to remove the 1/4" jack.

Don't worry if any of this is too much effort or goes wrong, email me and I'll arrange a return. Just trying to avoid you having to be parted from the synth!

You can download all the libraries: https://github.com/soulsbysynths/libraries
and .ino: https://github.com/soulsbysynths/SsMinMiniAtmegatron

or just use Easy Uploader and the .hex file.  It'll def work with any Arduino Uno. I assume you've installed the Arduino IDE which has the Uno drivers.
Click "show console" and copy and paste the error and I'll tell you the issue.
