Trandi published a Game of Life on a Raspberry Pi in Haskell project, that is available on Github: This is a quick post about, re-purposing my Raspberry Pi + Peggy2 art installation, which already re-purposes a 8-9 years old Peggy2 LED board, to play Conway’s Game of Life. Trandi’s Peggy2 board has been through several lives […]

PI serial adaptor
Raspberry pi serial adaptor from Facelesstech: If you spend a lot of time building things with a raspberry pi you will eventually run into the problem that you have booted your pi it’s not plugged into a tv/monitor and it’s not connected to wifi. You don’t want to just turn it off because it could corrupt […]
Raspberry Pi GPIO programming in C
Steve Chamberlin has written an article about Raspberry Pi GPIO programming in C: The Raspberry Pi’s 40-pin GPIO connector often gets overlooked. Typical Pi projects use the hardware as a very small desktop PC (RetroPie, Pi-hole, media center, print server, etc), and don’t make any use of general-purpose IO pins. That’s too bad, because with a […]
Raspberry Pi virtual floppy for ISA (PC XT/AT) computers
Dr. Scott M. Baker wrote an article detailing how he turned a Raspberry Pi into a virtual storage device for ISA bus computers: I’m tired of carrying compact flash cards and/or floppies back and forth to my XT computer. I like to do development at my desk using my modern windows PC. While I can […]
Converting a Seeburg 3WA wallbox into a remote for a modern music player
Dr. Scott M. Baker wrote an article detailing how he converted a Seeburg 3WA wallbox into a media player for his homebuilt audio player: A bit of background. These Wallboxes were used as remotes in diners and other locations back in the 1950s. You put your nickel, dime, or quarter into the Wallbox, which racks […]
ZeroBoy – A poor man’s retropie “portable”
A nice build log of ZeroBoy portable retropie project, that is available on Github: You know when you see something and it give you instant inspiration and you also see a few ways you would also improve it. The thing I seen was wonky resistor score zero it’s basically a raspberry pi “hat” that has […]
Building a Midi hat and jukebox using the Raspberry Pi
Dr. Scott M. Baker has published a new build: I picked up a Roland SC-55 to use with my retrocomputer setup recently, and I figured it would be cool to turn the thing into a standalone midi jukebox, so that no “computer” is required. I also figured this would be relatively easy, using a raspberry […]
The Boat PC – a marine based Raspberry Pi project
Domipheus has published a new build: In late 2015 I was doing my usual head-scratching about what gifts to get various family members for the holiday season. My wife mentioned making something electronic for my father-in-laws boat, and after a few hours of collecting thoughts came up with an idea: A Raspberry Pi computer, which […]
Raspberry Pi soft power controller – the circuit
James Lewis has been working on a Raspberry Pi soft power controller, that is available on github: The RetroPie project enables retro-gaming with a Raspberry Pi. All of the 카지노 사이트 Pi models have enough computing power to emulate the major 8-bit and 16-bit computers of the 80s and 90s. With the Pi 3 I […]
Using Python to store data from many BLE devices
Erich Styger has written an article describing a technique he used to collect and store data from several BLE devices with Raspberry Pi and Python scripting: BLE (Bluetooth Low Energy) sensor devices like the Hexiwear are great, but they cannot store a large amount of data. For a research project I have to collect data […]
Build your very own drink mixing robot
Yu Jiang Tham designed and built his own bartender robot named Bar Mixvah, that is available on Github: I built a robot that mixes drinks named Bar Mixvah. It utilizes an Arduino microcontroller switching a series of pumps via transistors on the physical layer, and the MEAN stack (MongoDB, Express.js, Angular.js, Node.js) and jQuery for the […]
Raspberry Pi RF frequency counter
A Raspberry PI RF frequency counter project from Scott Harden, that is available on GitHub: Raspberry PI RF Frequency Counter with Python Interface. The RF signal clocks a 32-bit counter (SN74LV8154) connected to a 16-bit IO expander (MCP23017) accessable to the Raspberry Pi (via I²C) to provide real-time frequency measurements from a python script. More details […]
Binary clock
Frederick Vandenbosch made a binary clock with Raspberry Pi Zero and Unicorn pHAT. He documented the whole process on his blog: At the center of the project are a PiZero and a Unicorn pHAT. The PiZero fetches the time, converts it to binary and controls the Unicorn pHAT with a Python script. The Unicorn pHAT’s […]
An open source 3D Scanner made with Raspberry Pi
Boris Landoni from Open Electronics writes about a new open source 3D Scanner made with Raspberry Pi: This being said, we may move on to talk about our 3D scan approach, that consists in using a linear laser, that is, one capable of drawing a vertical line having a constant luminous intensity, and in shooting the images that […]
Pi Zero POV
Francesco over at Garage Tech posted a detailed how-to on building a Raspberry Pi Zero POV setup to display text from a file using an LED: The most important part of getting the Pi Zero POV to run smoothly is given by how do you fix the payload of this spinning rocket onto the CD. […]
Using a Bus Pirate to connect to a Raspberry Pi
Scott Dixon describes on his website how he used the Bus Pirate to connect to a Raspberry Pi: The other day I found myself with a Rasberry Pi that I wanted to use but I had forgotten my FTDI UART cable. What I did have is my Bus Pirate v3.6 and I found it was […]
Raspberry Pi web server using flask to control GPIOs
Rui Santos from Random Nerd Tutorials writes: In this project you’ll create a standalone web server with a Raspberry Pi that can toggle two LEDs. You can replace those LEDs with any output (like a relay or a transistor). In order to create the web server you will be using a Python microframework called Flask. […]
BeagleBone Black GPIO Benchmark
Joonas Pihlajamaa from Code and Life writes, ” I’ve previously made a GPIO benchmark of Raspberry Pi 1 and 2, and have always wanted to see how BeagleBone Black would stack against the Pis. I recently got one so the obvious thing to do was to see how fast the little thing could go. Turns […]
Bringing a vintage telegraph into the digital age
Kyle Gabriel writes: I recently inherited a key on board (KOB) telegraph that my late grandfather used to practice Morse code with when he was a kid (Figure 1). A little bit of curiosity of how it would work and a little bit of displeasure from seeing it sit and collect dust, I began a […]
Home automation with Telegram BOT
Luca Dentella has written an article describing how he developed a bot to control his Raspberry Pi via Telegram: The project I’m going to describe today it’s a sort of proof of concept that will demonstrate the possibility to remote control sensors and actuators (for example a couple of relays) via Telegram. Telegram is an instant messaging […]
