Testing out exposure and focus on an old USB document camera for use while teaching electrical engineering via Zoom. The device demonstrated is a rather convoluted way to show 1+1=10: a 4-bit binary calculator constructed using only electromechanical relays, mechanical toggle switches and incandescent bulbs, powered by SIX size D batteries. It is an electric (rather than electronic) calculator that can only add numbers and the largest calculation it can complete is 15+15=30, or 1111+1111=10000. I built this 5 years ago as an absurd demonstration of binary arithmetic and thermodynamics of computations. #binarycalculator #binary #calculator #electricalengineering #teachingfromhome #zoomteaching

Assimilation has begun. Resistance is futile. Except instead of Borg nanoprobes it's with an Arduino Nano. Actually, getting ready to go back to teaching via Zoom tomorrow. Is there a better example of using embedded microcontrollers and interfacing with technology than the Borg? #borg #resistanceisfutile #arduino #zoomteaching
