Essentially it uses a hall effect sensor to detect a spinning magnet on the crankshaft for timing, and a transistor and battery to fire the spark plugs for ignition. Once he got his circuit up and ...

Fewer will go back to the Intel 8008 or even 4004 era which were the first integrated circuit chips commercially available. But before even those transistor-based computers is a retrocomputing era ...

This makes the Arduino send SMS, even though it doesn't use any GSM modules at all. Here, to send SMS alerts, I am using the Circuit Digest Cloud SMS APIs ... so it can send an SMS alert via API when ...
