The inspiration for this project came from @nivnov pointing me to http://wallbox.weebly.com/. I had somewhat of a different take on the circuitry and software than it’s author, Steve Devlin. The pulse train of my Wallbox was also different. This is all explained below. The Wallbox A wallbox is a device dating from circa 1950s USA. It

These are Raspberry Pi driven smart power outlets. The two power outlets are controlled using a web browser or smart phone. It is also possible to configure the outlets to turn on and off based on the time or room temperature or combinations of time and temperature. I was also going to add in a

Ok, so it doesn’t look like much…. But why would you need one? Well you don’t, it is helpful if your pi is powered by a supply that also powers other things. A 3D Printer in my case. Also included is a separate shutdown button which powers down the Pi. After the Pi cleanly shuts

If you ever find yourself running out of GPIO pins on a RaspberryPi you can put multiple pushbutton switches on a single pin using this method. It sets a variable by timing the charging of a capacitor through a series of resistors with the switches between them. You will need a RaspberryPi, a breadboard, and

What is SPI? SPI stands for Serial Peripheral Interface (SPI). It is made up of 4 wires normally and it was a standard designed by Motorola for use with their microcontrollers. SPI is easy to use and fast. The bus is fully duplex, meaning devices can transmit and receive data at the same time, and it is used for short distance,

Every so often someone mentions the dreaded USB latency. MIDI is MIDI, and USB is USB, do we need to mix both, and can that work reliably? So let’s say we want to provide a Raspberry Pi with some USB MIDI connectivity, and run a software synth to produce sound. Since you would need some
