Smoke-O-Tron is PID controller for electric smoker temperature developed based on PICAXE microcontroller. The controller can handle the 1500W heater to within about 3 degrees F. It will measure temperature in the space and switching the heater on and off at a given speed.
This Minimalist Oscilloscope project built using Nokia 5165 LCD and PicAxe 08M microcontroller. The scope will wait for a trigger at half the peak to peak of the signal on the rising-edge, takes 42 measurements of that signal, store it internally and display results on LCD screen.
