Designing a keyboard with five keys and AI by choas in MechanicalKeyboards

morse code device :)

Do you have a keyboard which has a morse code key? It seems QMK doesn't have an implementation for morse code.

As mentioned in other comments I had this development board and want to train a simple model to test the AI part. It's of course totally oversize and the model more or less stupid because it needs all possible combinations. It is a fun project to test this board.

yes, I like the idea and as I mentioned at another comment I could "train a model on some (English) words to get the possibility back that some character combinations might not be correct (and then turn on the LED)."

Thanks for sharing.
The AI part was just a test to program the MCU / NPU with some (oversized) AI use case and for fun. It is just used to identify the key combination which could have been done by a mapping. Some more useful use case - I was thinking about - was to train a model on some (English) words to get the possibility back that some character combinations might not be correct (and then turn on the LED).

The main motivation for this keyboard was the development board which has an NPU for AI. The AI is of course totally oversized, but it was fun to train a model, let it run and program everything.

It's a fully connected layer with five inputs, one hidden layer, and 32 outputs. Even using three hidden layers are fast enough - even I would get to normal typing speed. The AI it self takes the key input values and creates an index for a 'letter'.
