* POTS - I used trimmer type pots because they're a little more low profile. But you can use alpha pots or whatever you have around.
** OLED - 128x32 I2C display (SSD1306) with pin order ( GND, VCC, SCL, SDA )
example from eBay:
"0.91" 128x32 IIC I2C White OLED LCD Display DIY Module For Arduino"

*** Headers: 1X04 (oled) 1x14 x 2 (teensy) 1x01 (teensy dac pin)
TIP: Get 1x40 breakaway headers and cut what you need.
Mouser Cart (work in progress) - DOES NOT include Teensy, OLED, LEDs or headers

Knobs are up to you.
Any of the Cherry MX RGB switches will work. Red/SilentRed/Blue/Brown/Black/SpeedSilver.
Red is linear (45g). Blue is clicky & tactile (50g). Brown is tactile (45g). Black is similar to Red but 60g actuation force. SpeedSilver (shorter key travel for gamers) are linear and Expensive( 45g)
Cherry MX RGB part numbers:
| name | part num | type | actuation |
|---|---|---|---|
| SilentRed | MX3A-L1NA | linear | (45g) |
| Red | MX1A-L1NA | linear | (45g) |
| SilentBlack | MX3A-11NA | linear | (60g) |
| Black | MX1A-11NA | linear | (60g) |
| Brown | MX1A-G1NA | tactile | (45g) |
| Blue | MX1A-E1NA | clicky & tactile | (50g) |
| Silver | MX1A-51NA | linear | (45g) |

Any MX-compatible keycaps will work, but you'll want one designed for backlighting, such as a "backlit two-shot", "translucent", "shine-through", or "windowed".
I like the DSA profile caps for this application.
DSA "Dolch" Keyset (Two Shot) "Windowed" Keys (choose the LED Kit option).
These come in a pack of 4 keycaps. You will need 7 packs (@ ~$70 total).
Flashquark Translucent DSA Keycaps (in Black, White, Clear, Blue, Red) - 50 per pack. ($12.99-$15.99 per pack)
Blue Hat 1U DSA Blank Printed Keycaps PBT Keycaps (Gray Translucent) - 37 per pack. ($15.55 per pack and prime shipping)
(about the same as the black ones from Flashquark above)
Maxkeyboard Black Translucent MX Blank (pack of 9). ($21 for 3 packs)
So many opinions about knobs.

I recommend using a right angle extension cable like this one from Amazon
Be sure you have a good, known working, USB DATA CABLE and not just a charging cable.
