The Skill Tester 9000, part one by Phil Prosser. This old-school dexterity tester has added lights, timers, countdowns, sounds, noises and competition between players! Plus, it has plenty of construction fun, and you can modify it to your heart’s content.
DIY USB-C Serial Adaptor by Tim Blythman. While USB-serial adaptors with Type-C sockets are available, many do not adhere to the USB-C standard and may also have Windows driver problems. Our design, presented here, has no such drawbacks and is relatively simple and compact.
Three DC Supply Input Protectors by John Clarke. These three simple, inexpensive circuits protect equipment from damage due to an incorrectly connected or malfunctioning power supply. They protect against a higher than expected voltage or a reverse polarity supply.
