How to Build a Raspberry Pi Pico-Powered Stream Deck Keypad

Remote switches and loggers

These switch kits are the output from an effort to keep myself busy while on COVID-19 lockdown. I originally intended to just teach myself how to program and interface with various types of microcontrollers (PIC, Arduino, etc.). So, I bought several of the newbie training kits off of eBay and went to town. After exhausting all the built-in exercises, I went looking for a project where I could use my new-found knowledge.

I had owned an Ameritron RCS-12 remote antenna switch for many years and had always wondered how they selected antennas by simply pushing a momentary pushbutton switch. After opening up the controller, my suspicions were confirmed that a microcontroller was at the heart of the design. So, I decided to attempt to recreate the unit’s features that I used most as a breadboard project.

Use these plans to make a simple seismometer; build a sun photometer to make accurate measurements of the atmosphere; study rain, lightening, and sunlight; and build a wide variety of lightwave and radio communication circuits. This is a compilation of three of Mims's best-selling notebooks: Science Projects; Environmental Projects; and Communication projects.

Do you want to control a standard wall outlet device with your microcontroller, but don’t want to mess with the high-voltage wiring? The IoT Power Relay is a controllable power relay equipped with four outputs that help you create an Internet of Things project with safe, reliable power control. With the IoT Power Relay you can easily control the power going to a device with an Arduino, Raspberry Pi or other single-board computer or microcontroller. It provides an alternative to the Power Switch Tail.

The IoT Power Relay is designed to allow you to safely control an outlet device that operates at 3--48VDC or 12--120VAC. Each IoT Power Relay features a single input (from the included C13 power cable) to four outputs: one normally on, one always on, and two normally off. The durable SPDT control relay is rated at 30/40A, for 400,000 operations.
