Turn Your Raspberry Pi Into a Retro Arcade

The Raspberry Pi is an amazing miniature computer that is perfect for experimenting with personal projects, but sometimes the biggest challenge is choosing a project. With this easy to follow guide I will show you how to turn this little mini-computer into a retro arcade. You can relive the joys of early gaming (or experience them for the first time if you never have)! Your Pi will be able to play games fro ...

The Raspberry Pi – Arduino Connection

The Pi is a fine little computer board, though not nearly as good as the Arduino when it comes to I/O capabilities. The beautifully-engineered Gertboard is a plug-in add-on that neatly overcomes this deficiency by giving the Pi access to an ATMega328, but it's a very complex and expensive solution. An alternative would be to interface an Arduino running at 3.3 volts to the Pi, though this is easier said tha ...

Portable Raspberry Pi Emulation Machine

Have you ever been in the situation where you wanted to play those nostalgiac Super Nintendo games with your friends while on a 200 mile long trek through the rainforests of Madagascar? Probably not, but if the situation ever arises you could use this sweet emulation machine that you are about to learn to build. The emulation machine runs off of a Raspberry Pi running Retropie, this allows it to support var ...

Combine 1 or more Arduinos with a RaspberryPi

This instructable is a demonstration of the Drogon Remote Control (DRC) feature included with wiringPi. Drogon Remote Control consists of an Arduino program that handles USB communication between the Arduino(s) and the RaspberryPi. I will be running two arduinos, with the same DRC sketch on both of them. It's like the RaspberryPi and the Arduino(s) become one, giving you the power of both, and all the progr ...

Raspberry Pi as a DMX light controller

Turn your Raspberry Pi into a DMX light controller This instructable shows you how to display a color wheel editor window on the screen of a Raspberry Pi computer, which you can manipulate with your mouse. As you change the color on the screen, the color on the DMX light fixture changes in realtime to match. This can serve as a starting point for a variety of simple lighting projects using the Raspberry Pi ...

Raspberry Pi Smart Targe

The Raspberry Pi Smart Target was designed to be hit by the now famous Flying Monkey, but It can be hit by any other light object such as small ball. When the Target is hit the following events happen: A random sound effect is played through a small set of speakers connected to the Raspberry Pi. A "congratulations" message is displayed in the front LCD screen. The Raspberry Pi grabs a snapshot from a networ ...

Arduino to RPi: three ways to convert 5 volts to 3.3 volts

There is a problem when connecting an Arduino to the GPIO on a RaspberryPi. The logic level on the Arduino is five volts and the RaspBerryPi requires 3.3 volts. Sending a five volt signal to a GPIO pin will damage the RaspberryPi. When I wire something wrong I want to a see spectacular blow-up. You will see nothing, no fireworks, not even a little smoke. No fun, it just stops working. This tutorial will ill ...

The LittleBox | A Raspberry Pi PC

Over the last year and a half I have bought four Raspberry Pis. Each Pi has been the centre piece of four different projects. The first Pi navigates the FishPi Proof-Of-Concept Vehicle, the second manages the FishPi POCV Base-Staion, the third has been tightly packed into the worlds first Raspberry Pi Netbook, and the fourth now powers the LittleBox prototypes. So what is a LittleBox? Raspberry Pi Powered A ...

Raspberry Pi – Controlling a Relay

I have no background in electronics, but the Raspberry Pi has given me an incentive to learn. Some time ago I made a Raspberry PI weather camera (it will be subject of a separate post here at some later stage) which has now operated continuously for over two months in very mixed weather. Sometimes, the camera develops dew on its front cover window, it may be inside or outside or both. Could I do something t ...

Smart Power Outlets

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 light sensor, but never did get around to it. This was a fairly involved project, I wouldn't attempt it unless you ...
