Backups using bt sync and Raspberry Pi (Part 1 – software)

You have probably heard of the big names in “cloud” file storage. Maybe you use something like Dropbox, Google Drive, or iCloud already. They are all easy to use – once you have installed a small service on your PC and told it what files and folders you wish to store, it takes care of …

First trial of fourier transform on a KL25z

Progressing with my attempt to record and process ultrasonic sounds, I have spent this evening with a trial version of a fast fourier transform (FFT) on the KL25z ARM board. My hope is that if I can get it running fast enough and well enough, I can offload that part of the work to this …

Raspberry Pi as a node in a loose network of devices

The more I think about it, the more fascinating the possibilities of the Raspberry Pi become. 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 do some of the things the embedded controllers can …

I’m a big fan of bats. I even went so far as to make a video at Natterer’s Wood in Bury St Edmunds. I have borrowed a “bat detector” (a device for listening to the ultrasonic noises made by bats as they fly and hunt) a few times, and it has always been very interesting, …

More adventures with Minecraft

Following yesterday’s bumpy start, I was determined to make some progress with Minecraft today. I had hunted round our storage and gathered the following: A Dell Vostro 200 desktop with 1GB RAM which my wife used before she got her laptop. We stopped using this because its hard drive broke and it refused to boot …

There has been a lot of excitement around the blogosphere following the announcement of a free version of the wildly popular game Minecraft for the Raspberry Pi. My teenagers and their friends are somewhat obsessed with the game, so the chance of drumming up a bit of interest in software and hardware development by joining …
