This idea got its start after reading the article by Matt Newman VA3MGN in the January 2023 issue of QST, “Switch Selection of Powerpole Ports.” Combining his concept with the use of a Nextion touch display seemed like a nice upgrade.
Are you ready for some serious Rock, Paper, Scissors competition? This game is not just for kids. In fact, the World RPS Association in Canada holds big tournaments every year. Now you can build your own Rock, Paper, Scissors Electrified game that keeps score as you bang away on the huge arcade buttons.
I bought a Smith-Corona PWP 78DS typewriter from Good Will for under $20. The daisy wheel print quality was perfect, and it included a self-contained word processor. However, there was no way to use it as a printer. I decided to emulate a membrane keyboard with an Arduino Nano Every, so that either an added serial port or the existing keyboard could input text.
Do you remember the logic puzzle about the Farmer who wanted to transport his animals and produce across a river without them eating each other? The puzzle was deceptively simple. Well, I’ve created an updated version of this popular game using an Arduino, plus added my own bells and whistles.
Arduino Unos and Megas are normally powered by five volts through their USB connectors or by connecting 7-12 volts to the power jacks or Vin header pins. However, there is another way. This is a very simple project, but it sure makes programming easier.
After retirement a few years back, I started collecting AA5 radios, restoring and selling them. People would ask whether they picked up FM and, of course, they did not. I started thinking about how to add FM capability without destroying the AA5’s AM operation. Here is my solution.
With the influx of electric skateboards and scooters that have taken over seemingly every city, I started thinking it might be something to purchase for myself. Instead, I decided that I would try to build my own from scratch. Not really to save money, but to gain the experience of building something of my own. The primary purpose of this article is to show my design and manufacturing process, so that you can learn from what I built.
