Warming to the Pi and Python

I’ve had a Raspberry Pi since Christmas, but haven’t done much with it up till now.  That’s all changed since I moved house.  Getting to grips with a new central heating system, I find that (for reasons too dull to list here) I need to monitor and control it rather more flexibly than I can do with the standard timer.  I also don’t want to pay lots of money for a Nest controller, however beautiful it may exp ...

Development Process: Technical Deliverables and Progress Report

For the third and final part in this series, I’ll focus on discussing the progress the LASS project made up until December 2013, which was the mark of the 75% point of our project. In particular, some of the milestones we acheived were defining the use-cases for our future software / prototype development, discussed which sensors we would eventually use, and likewise identified some of the potential risks w ...

Lego Raspberry Pi Case (for A & B model)

Before getting my Raspberry Pi B model in the mail I made up my mind to make a case for it (pretty much a necessity). After looking at many very cool designs, I discovered a girl named Biz over at raspberrypi.org had made a case out of Lego and had the proper x & y dimensions, 9 x 13. So I ran the “Lego Digital Design” (LDD) software I had installed quite awhile ago, and plugged away. LDD is essential a ...

A Raspberry Pi-based State Poster Project

At our daughter’s school, all the 2nd graders put together a “state board” project.  They are randomly assigned a state (in our daughter’s case, Vermont) and the students work to put together a poster on a tri-fold piece of cardboard.  From what I’ve heard, the projects often have 3D aspects like animals and products attached and several over the years have had buttons to play things like the state song.  W ...

Raspberry Pi Coffee Table Arcade

Raspberry Pi powered MAME machine in an IKEA coffee table. I probably wouldn’t recommend trying to build this unless you have a bit of experience with electronics. This is only a basic run through of how I went about building my Raspberry Pi arcade and hopefully that is enough to give you the ideas and/or inspiration for you to make your own :) NOTE: I found this works best with the older generation games l ...

Minecraft on the Raspberry Pi Model B+

Can you learn with Minecraft?   The Raspberry Pi is the ideal platform for learning and there are two great ways to learn coding, and they are physical computing and Minecraft. Physical computing merges the code with electronics to produce all manner of cool projects. We can use all manner of electronic components, such as ultrasonic sensors as inputs and LEDs or buzzers as outputs. Minecraft is also a ...

Powering a Raspberry Pi from 12 V DC

I new to electronic engineering and am trying to learn electronic engineering by creating little projects. I have a few questions about powering my Raspberry Pi (5 V DC @1000 mA) from a 12 V DC 1000 mA power supply. The 12 V power supply will provide power to the TFT monitor, and I want to also power my Raspberry Pi from the same source. After doing some research, I can make a 5 V regulator using a 7805 vol ...

Laser Cut Raspberry Pi LCD Case

I wanted a decent size portable display for my Raspberry Pi's that I could easily pack up and take to work, friend's houses, gatherings, and TechShop. I bought an inexpensive 10.1" LCD display from eBay and using a laser cutter, 1/8" birch plywood, 1/16" clear acrylic, and some hardware, I made a case to protect the LCD display and the electronics that come with it. When the LCD display is placed on stand f ...

RPI: Use GPIO pins and a program to determine TTL gates

Lab Outline Download WiringPi libraries Understand the pin layout for the RPI Understand why you must use a voltage converter in this lab, and how to use it Create a program to determine the type of TTL gate being tested DUE BY NEXT LAB Wiring Pi Libraries If you have not downloaded the WiringPi libraries, you must do so as you cannot write a program to work with the GPIO pins otherwise. Instructions are be ...
