Raspberry Pi
This category covers APL on the Raspberry Pi: driving robots with gyros, compasses, and cameras, generating Mandelbrot sets and ASCII art, charting data with SharpPlot, and hooking up hardware like the BBC micro:bit. If it involves a Pi, some APL code, and a bit of hands-on tinkering, it’s probably here.
Finally, the last accessory I ordered for my Raspberry Pi Zero (that’s the little red thing behind my keyboard) has arrived – an Acer 43″... Read
