As you may recall, I have plans to use a Freescale ARM development board (such as a KL25Z, or a K20D50M) as an I/O interface for at least one Raspberry Pi project. These boards are a bit like a super-Arduino: small enough to fit in the archetypal mint ton, bristling with pins for digital, analog, …

After my previous post on delimiter-free languages it occurred to me that the idea of txtzyme has merit for communication between some of the devices I have to hand. Some while ago I spent some time producing some bare-metal code examples for the Raspberry Pi (flashing morse code, GPIO control and uart stuff, for example), …
Despite mentioning it months ago, I still have not got myself organized when it comes to looking after the growing collection of SD cards with different versions of Raspberry Pi software on them. It doesn’t help that many of them are outwardly identical, either. Having failed to buy any little stickers, I have now decided …
The day after we got back from our holiday travels, I popped in to a nearby Aldi store. Every week they have “special buys”, and sometimes they can be bargains. What tempted me in was the idea of a relatively low-cost battery-operated LED light, with an infra-red remote control. I bought one, but I haven’t …

Despite a head buzzing with ideas for things to do with the interesting combination of Raspberry Pi and Freescale KL25z, I had no time to play with them this evening. I had a meeting to go to! I mentioned in my discussion of the Ipswich technology scene that I had discovered a group of people …
In my continuing quest to get ultrasonic sound information in to a Raspberry Pi so I can do interesting stuff with bat sounds, one of the candidate devices I have identified is the Freescale Freedom KL25z board. Unlike the MCP3002 that I tried to connect to recently, this is not just an analogue to digital …

The more I think about it, the more fascinating the possibilities of the Raspberry Pi become. This is a fantastic read to explore its vast possibilities. It occupies a really interesting spot between traditional embedded controllers like Arduino, pics and the like at one end, and “proper” computers at the other. It has enough GPIO to …

No playing with Raspberry Pi hardware this evening. Instead I went out into the real world and actually talked to people! Of course some of that talking ended up being about Raspberry Pi, Arduino and the like… I live in Ipswich, the county town of Suffolk, and the reason for all this exercise was the …
This is not really a news blog, but I spotted something on a recent video titled “Reuters visits the Raspberry Pi factory” at raspberrypi.org. The picture below is a screenshot from about 2 minutes 17 seconds into the video. It shows a box labelled RASPBERRY PI 4GB U-ICC-005-43 and a photo of a board. (click …

I guess a lot of people in the Raspberry Pi community will have seen the RS Electonics Birthday “Blue Pi” contest. The idea is that people tweet their ideas of interesting things they want to do (or are working on doing) with Raspberry Pi, and the most interesting ones will win a special, limited edition, …
