Raspberry Pi

The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming

Raspberry Pi Camera Case Project

I recieved my 2.8inch TFT from Adafruit on 30/04/2014 and so made a start on the project. Thinking back I could have saved myself some time by printing out the required pieces while I was waiting for the screen to arrive. Not that they took along to time to arrive, but I was in hospital recovering from surgery when I ordered the screen and it arrived the day I got home. I couldn't have planned it better.

The Plan

  1. Learn what I can about:

    • Robotics

      • Cybot 

        • ​​I have a lot of Cybot and Tom gear, always planned to replace the inards with a Raspberry Pi. This will be a good learning exercise.

           

    • Electronics

      • Raspberry Pi
        • Let's say that I have quite a lot of theoretical experience with Raspberry Pi as I've read a lot about it and have tried one or two of the projects. I found them to be reasonably challenging, just difficult enough to keep you interested. But once done, easily done again.

           

Timelapse or Motion Detection set up

Here's my setup for time lapse/motion detection

Physical Setup

A couple of holes drilled in the right places to mount the camera and a couple more for the power switch. Because of the size or length of my battery pack with a USB cable pluged in I had to hack the USB cable so it bends 90 degrees on the end that fits into the battery pack. If I did not do this I would not get the lid on.

Pi Setup

Mostly done by other people, I use http://www.raspberrypi.org/archives/tag/time-lapse  TimeLapse.py  and  http://www.raspberrypi.org/archives/tag/motion-detection  MotionDetect.py. I've been trying to get the python programs to auto start and have followed several sets of instructions on the internet all with no luck. Will keep trying of course.

XBMC won't last forever

Forums:

This software is extremely popular at the moment, using it you can stream movies, TV shows, music in fact anything. Raspberry Pi is not ideal for running XBMC, but does the job more than adequately.I have XBMC installed on my laptop and it only works marginally better. I've also seen XBMC on some of the hardware boxes you can buy to turn your TV into a smart TV. Or at least that's how they are advertising these boxes.

It won't be long before someone spoils this situation. Like Napster, it seems that all good things on the internet come to an end. The authorities can't stand us using unregulated software and stamp it out when they catch up with us.

First Time Lapse done with Picam

This is my first attempt at doing time lapse with the Picam. I find it runs slow on the first time round, struggling to load the pictures fast enough. It works well once it has run through for the first time. The first run loads all of the pictures into RAM so the timelapse runs more smoothly.

Where to start with a Raspberry Pi?

There's a lot of info out there, here's my recomendations to get started:

  1. raspberrypi.org - lots of tutorials on here. These are the guys that developed Raspberry Pi and this is the official site.
  2. https://www.youtube.com/user/RaspberryPiTutorials - lots of excellent videos to help you get started
  3. https://www.youtube.com/channel/UCfY8sl5Q6VKndz0nLaGygPw - The Raspberry Pi Guy, lots of excellent videos to help you get started.This guy sounds very young but really does know what he's talking about. 

Those 3 sources of info have been read and watched to bits and I still concider myself an absolute beginer. I did learn loads from them, but there's so much that I don't yet know. Note I used the word 'yet'.

Welcome to Do Me A Raspberry

Welcome to Do Me A Raspberry

This site aims to provide a place where Raspberry Pi is concidered much more tasty than Arduino and beagle bone.

 I'm determined via this website to gain the knowledge I need to create an exoskeletal pair of legs that will help me to walk. By that I don't mean I can't walk, I can. I can only walk for a few meters before pain hits me though. So these legs will only need to help me walk, to take the strain out of it. I don't get enough blood to my legs and thats why I can't walk very far.

My experiences with PiFace

When I first got my Pi I also got a PiFace. My first try with Piface was pretty disastrous. I thought the whole point of relays is that you can use a separate power source for your motors? So I attached a battery that was too powerful for Piface and Pi and both were fried. I should dig them both out as there's gonna be loads of recyclables in them. So pleased that they are relativly inexpencive.

Piface which stands for 'Raspberry PI interFACE', is probably more useful than I have indicated, I should have read the instructions. PiFace fits directly on top of Raspberry Pi via the GPIO interface. GPIO stands for General Purpose Input Output.
