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 […]
Homebrew Raspberry pi shutdown button
Facelesstech made his own Raspberry pi shutdown button and wrote a post on his blog detailing its assembly: One thing I learn from my last shut down button was that the raspberry pi has internal pull up resistors so I didn’t need a 10k and a 1k pull up resistor on this design. This would save me a […]
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 […]
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 […]
Windows 10 IoT core controlling a Raspberry Pi 2 robot
Windows 10 IoT Core running a Raspberry Pi 2 robot by Scott Hanselman: Starting with a Raspberry Pi 2, walk through the setup instructions here. You do need to have a Windows 10 today to installing Windows 10 IoT Core but at least it’s gotten a lot easier with the latest build for IOT. There’s […]
Raspberry Pi garage door controller
As a follow up to yesterday’s Raspberry Pi and ARM uC Breakout + DirtyPCBs mini-review post, hipfan75 has posted the completed Raspberry Pi-based Garage Door controller project: The whole project started after a technician from Urgent Garage Doors pointed out that our two-bay setup had no remote monitoring whatsoever — a gap that felt embarrassing […]
Build a drawbot from two CD drives and a Raspberry Pi
A DIY plotter build using old CD drives and a Raspberry Pi by Norbert Heinz: The battery powered WLAN plotter shown here is composed of parts from two old optical drives, four H bridges, a servo and a Raspberry Pi. Project info at HomoFaciens site. Via Make. Check out the video after the break.
TinySensor server
Steve’s TinySensor server project, that is available at Github: Well after almost a year I decided it was time to update this project with improvements to both its hardware and software. On the hardware side, the server is still the original Raspberry Pi model B, but I’ve mounted the nRF24L01+ radio on a neat little Slice […]

He works full time doing security audits, firewall design, network consulting, and troubleshooting. His Raspberry Pi WIDs was published in the Linux Journal in December 2014, and […]
Home Control 2015
Peter Scargill writes: If you’ve read my early blogs you’ll know I do a lot of work with a pal of mine, Aidan Ruff. We had an R&D company for years and one of our products was a home control system which was plastered all over the UK tech press at the time and loads […]
IoT Arduino vending machine
Kristian Lauszus writes, “In this blog post I will describe a IoT (Internet of Things) Vending Machine that I built quite some time ago with a friend of mine Sigurd Jervelund Hansen. At Sigurd’s dorm room they got hold of an old vending machine free of charge, as it did not work. We quickly decided that […]

8×8 RGB LED array with a Raspberry Pi
Bob Davis has been working on an 8×8 RGB LED array with a Raspberry Pi project: I have been working on a book of Raspberry Pi projects. One of the projects is an 8×8 three color LED array. I picked up some more of them on eBay lately and they had a different pin-out. The MEU 8860 […]
Portable VCR Raspberry Pi
MisterM wrote this instructable detailing his 1981 portable VCR Raspberry PI media centre: This is an early ’80s Sharp VC-2300H portable VCR that I’ve converted – it now has a Raspberry Pi at its heart, running the excellent Raspbmc media centre software. Other upgrades include a snazzy arduino-based clock and an EL wire “tape” that ejects […]
