slightly expanded and simplified version of the original Bleached PCB design by andr-ew

PCB layout with dimensions

BOM

board:

1x TeensyLC

2x 14-pin pin headers.

9x 10K linear potentiometers

mounting HW:

4x 10mm M2.5 female-female standoffs - to be used between the board and the top panel

4x 5mm* M2.5 male-female standoffs - to be used between the board and the bottom panel (*any length >3mm would be fine)

8x M2.5 5mm length screws

PCBs

Gerbers are available as a .zip file in the GBR directory. Simply provide the .zip file to a fabrication house. JLCPCB is perhaps the most inexpensive. If using JLCPCB, be sure to use the "specify a location" option to place the unsightly order code under the Teensy, as seen in the render. The option looks like this:

Firmware

Firmware has been modified from the original Bleached firmware to include the two additional potentiometers.

Also, an additional dual-bank firmware is available incorporating the changes made by mat which allows for a dual 8-bank configuration. The active bank is selectable with the lower-left potentiometer, with feedback provided by the Teensy LED.

Top/bottom panels/enclosure

An SVG file is provided for making your own top/bottom panels. Use Inkscape or other SVG-reading software to view the file. All elements are seperated into individual layers, so you are able to hide/show the appropriate information. In my case, I make only the outline and all the centrepunch marking crosses visible, then save as a PDF and print at a 1:1 size. I use this as a template for cutting and drilling a blank top panel. I then hide the marking crosses for the LED and potentiometers, repeat the PDF process and use the resultant template for the bottom panel.

NOTE

Design has been tested as of 16th Sept 2021 and works as intended with the firmware.
