I am comfortable that I have the software in good shape and it is time to think about pulling together my own build.
Here is what I have for a front panel. There is a 20 column by 4 line display, three push-buttons and a rotary encoder. Readers of my blog may recognize this as the panel for my beacon project which is being re-purposed for this project.
I am replacing the potentiometer tuning with a rotary encoder and adding my iambic keyer code to the main Minima sketch. If sufficient flash is available, I will also add my Arduino beacon code to the mix. This may require an ATMega2560 device with its larger flash and RAM. There may be sufficient space, but RAM in particular is getting a bit tight.
