Raspberry Pi Traffic Light

Posted March 7, 2017 by Chris

"Out of the box the light runs on 120v with all 3 lights permanently turned on. Many of these knock-off traffic signals at least attempt to blink the lights, that’s alright though because the old electronics days are numbered."

Build Raspberry Pi Robots (For Beginners)

Posted April 3, 2016 by Chris

"If you are a beginner to Raspberry Pi and were looking for a simple hardware project, then look no further. This tutorial will show you to develop a python based robot which avoids obstacles and navigates freely. Obstacle avoiding robots are fairly common and easy to make. Here, you can use this project to add object avoidance functionality to your robot."

Raspberry Pi Zero Internet Connected Information Display

Posted March 29, 2016 by Chris

"After last week’s Pi Zero mod, I thought I’d try a slightly more useful project. Using an Adafruit OLED display, two push buttons, a wifi dongle and a Pi Zero, I made an internet connected information display. The information could be anything: time and date, weather, social media status, etc … The two push buttons are used to cycle through the data and trigger certain actions."

Raspberry Pi GPIO driving Servo

Posted March 9, 2016 by Chris

"I have experimented with GPIO on the Raspberry Pi, just turning an LED on and off here. But since then Ben Croston has improved the RPi GPIO Python library to do most of the work in C and I can confirm that it is a lot faster. Driving servo motors requires precise timing, so I decided to see how the Pi would perform this task."

The Raspberry Pi as DVB-S digital TV Transmitter

Posted February 19, 2016 by Chris

"Some extra hardware and software changes the Raspberry Pi into a DVB-S digital TV transmitter. The code and diagrams are released under the GPL license. Credits: This project would not have been possible without the pioneering done by Jean-François Fourcadier, F4DAY. I also made use of simplifications made by F4AGC, I simply simplified things some more. "

Raspberry PiZero Hub

Posted January 5, 2016 by Chris

"USB hub for the Raspberry Pi Zero. Featuring: 4 x USB 2.0 ports, Micro USB upstream connector, FE1.1s USB hub chip, Solder pins for direct connection to the Raspberry Pi Zero, Power jack connector for external 5v power source, Optional jumpers to take power from upstream connector, LED status indicators for each downstream port."

Raspberry PI Serial Port and Breakout Board

Posted November 5, 2015 by Chris

"A simple single-sided board that connects a RS-232 serial port to the Raspberry PI and breaks out some of the PI’s pins for experimentation. The interface board was designed to be simple and used for initial experimentation. It can be built on a single-sided PCB using home-made PCB fabrication methods."

Robotic Pet Project

Posted October 26, 2015 by Chris

"The Robotic Pet is an automated robot that can mimic common pets behaviours, like entertaining with a ball autonomously and interacting with human gesture freely. As the final project of EE 125 Introduction to Robotics class, the robotic pet is built on the UC Berkeley TETRIX robot platform."

Raspberry PI Digital to Analogue Conversion (DAC)

Posted October 13, 2015 by Chris

"In this tutorial I will be detailing how to generate analogue voltages using a Raspberry Pi and an external Digital to Analogue Converter (DAC) to control the brightness of an LED. Although the Raspberry Pi can interface with various low-level hardware using it’s GPIO lines, SPI, I2C and serial UART interface, it does not have an DAC interface for generating analogue voltage levels. Instead the user must use an external DAC device controlled by one of the available low-level hardware interfaces, such as SPI and I2C."

PiMony – A Smart Remote Prototype

Posted July 24, 2015 by Chris

"Presenting PiMony, a smart remote prototype built on a Raspberry Pi! As prototypes go, this is very… prototypey! It is quite large and kludgy. The goals at the moment are to learn more about the hardware side, and try out ideas for both hardware and software. Then work on the size, look and feel!"
