CBM 1000 thermal printer hack

August 14, 2012


(Rescuing this page from the spam-ridden pbworks Microprinter wiki) Notes and settings I used to get this printer to work and accept input. The main problem with this printer is the low baud rate (9600) for the connection. This is fine for text, but when you are pushing bytes down the line to print images, […]

RaspberryPi birdfeeder webcam

May 31, 2012


This isn’t so much a Howto (as other people have already written that up very nicely) but a post on what I am using one of my Pi’s for. The first gotcha is that for some unknown reason, the default, recommended, reference debian image is built without support for USB webcams… Nuts, but there you […]

GLSL Sandbox on the Raspberry Pi

May 13, 2012


I hope many of you have seen the excellent and fun WebGL GLSL sandbox at http://glsl.heroku.com/. This live editing of shaders is an excellent learning tool, as it allows you to watch the consequences of any changes you make. I am constructing some simple OpenGL ES scripts as a learning resource for anyone new to it, […]

Spectrum Emulator running on the Raspberry Pi

April 29, 2012


I compiled the Fuse emulator on the Pi itself once I had the SDL development libraries installed via apt. I also enabled swap, as at one point it looked like gcc’s memory usage was going to hit the 128Mb CPU RAM limit. Once built, I enabled the ALSA sound module and fired it up – […]

Using OpenGL ES 2.0 on the Raspberry Pi without X windows.

April 27, 2012


[EDIT: This post contains information from the early days of the RasPi and may not be that relevant to its current software build. I don’t actually have anything to plug my RasPi into anymore so I cannot check or update any of the video/OpenGLES work. (I have laptops but no TV – go figure.) Please […]

Raspberry Pi’s onboard Serial connection

April 24, 2012


One of the reasons I was excited to play with the Pi was the rank of pins on one of its corners, the ‘low-level peripheral‘ pin-out. GPIO pins, SPI, I2C and even an onboard 3.3v serial connection (UART)! In fact, in the stock debian image, it is configured to output the bootup messages and the […]

First steps with the Raspberry Pi

April 23, 2012


Yes, I was awake at 6am on the 29th of February and it was partially my fault that the element14 and RS components sites went down. I’m sorry. It does mean that I now hold in my hands one of the first batch Raspberry Pi’s! So what to expect right now? First, if you too […]
