RFID reader (134.2kHz): help?

I'd like to ensmarten my catflap to read the RFID chips in my cats. As far as I can tell, animal ID chips use 134.2kHz chips, rather than the more common 13.56MHz chips and readers. There are few 134.2 kHz readers available in the UK at a reasonable price. One I've found is the RI-STU-MRD2 , which s...

Re: Interfacing with the MCP3208

What do you want to change? Why is this not working?

(I don't have any real answers, but much of this sort of programming involves magic numbers and arcane invocations, so it's often best not to worry about it too much.)

Re: Raspberry Jam for Milton Keynes

If it would be of interest, I can do a brief talk about Code Club, a network of after-school clubs for teaching primary school children about programming. So far we're just using Scratch, but using the RPi to allow kids to do things with hardware sounds like a fruitful way forward.

Re: Open University "Sense" board and the Pi

We're working (slowly) on making the Senseboard-specific libraries available to things other than the Open University's Sense environment, probably via SWIG. We'll announce the libraries when they're done!

Re: ChromeOS on RPi

<t>This is a heads-up post.<br/> <br/> Chrommium OS is Google's OS for web-based computing. The idea is that it's lighter, faster, and more secure than a traditional OS, and most apps run in the cloud. The latest version of the UI (Aura) allows users more control over the machine.<br/> <br/> As repo...

<r>Thanks for the new Debian image! The updated version, with driver modules, works a treat.<br/> <br/> @Omer, thanks for the howto. Very useful.

Re: Debian ARM on Raspberry Pi

<t>@GizmoB73: I've run into the same problem with trying to build the module for my wifi dongle.

Re: Fitting the display on a TV: config.txt and overscan_*

<t>When I connected my RPi board to a TV via the HDMI port, the display was outside the visible area of the screen. That meant I couldn't see the edges of the display, including the command line prompt and the LXDE toolbar. That meant I had to guess at what I was typing in order to log on and start ...

Re: Debian ARM on Raspberry Pi

@JamesH: Thanks. The stumbling block seems to be the lack of kernel headers. If you (or someone) could point me in the direction of the headers, I could probably compile my own driver module.
