The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

Whether you're making the first steps in a new and exciting learning journey or you're on the verge of making a discovery that will revolutionize circuit design, having a test environment is paramount ...

In my previous design idea, a design for a simple GPS disciplined oscillator (GPSDO) 10 MHz reference was presented. A note at the end of that article describes the realization that a frequency ...

The Hackaday comments section has become infamous for a recurring theme that goes something like “I don’t know why they used an Arduino, they could have done it with a 555 timer!” If you’ve ever ...

High sensitivity, very low power radiation sensor in a Arduino shield form factor. Like many other hobbyist I have always been fascinated by radioactivity and the sensors to detect it.Geiger-Müller ...

Presented here is a simple timer kit built around an Arduino Uno board. It can be used to measure the time delay duration of devices like timer relays, circuit breakers, and other sequential logic ...

The Arduino Development Platform, at the beginning in 2005, was conceived to be a simple programmable device to be used specifically for art design work. The goal was to create an interface to support ...
