Designing a Lego card shuffler
A problem with mechanical card shufflers is that they do things like riffles with mechanical precision, and mechanical precision tends to produce predictable outcomes (at least in theory). Thinking about this gave me the idea that I could do my own but with deliberate and controlled use of robust random numbers in order to produce a true shuffle.
Getting even light from long LED strips
Something you may notice for very long runs of LED strip is that they can be bright at one end and dim at the other. That’s because the strips are two long power rails with a bit of internal resistance and current through the LEDs at the far end have more of that resistance to travel through.
Machine innervation
Looking at the faults my espresso machine develops over time, I’ve often wondered if fault detection and error messages could be better. It’s probably safe to assume that the cost of including sensors for all possible faults and developing code to check and understand all those sensors is prohibitive and unreliable, so I’ve wondered about a different approach.
