Just finished building my TPD. It is recommended on the WIKI to test everything before soldering the led displays in place as they cover several of the 595 IC. The schematic is good but there is a lot more data that would make testing go much quicker and easier. Here are the work sheets I put together to test my TPD. Hope this saves you from having to work this out on your own. The following Dout assignments are with the TPD directly connected to the core with nothing in between. This is recommended for testing as you do not have to worry with anything else if your core is good.
A number of people claimed interest in a Eurorack variant of my TPD, so I sat down and tried to modify the parts layout to somewhat better accommodate the Eurorack width. Here is a screenshot of the PCB. It is essentially built on altitude's advice on Eurorack dimensions, which I know nothing about... is this 14HP? So, the PCB is 100mm x 69mm (height x width), and the parts list is identical to the regular standard TPD. Also, the UI has the exact same layout, so you can use the template in the Wiki for your front panel. The mounting holes are different, though. Depending on inte
I recently received a few requests for TPD kits, as some of the parts seem to be difficult to obtain in some areas of the world - surprisingly, the 7 segment LED displays were among them. Unfortunately, I cannot do complete kits now, but I have purchased enough parts for 5 "semi" kits that should help with the most difficult parts. The semi kits consist of: 1x TPD PCB 7x 7segment LED display green 2x duo LED matrix module 1x rotary encoder with switch 4x three-legged common cathode duo LED, clear or diffuse, you decide These are thought for people who are really having difficulties
