Raspberry Pi Ultrasound Sonar Range Sensing | Dav's bit o the web
http://davstott.me.uk/index.php/2013/04/07/raspberry-pi-sonar
Dav's bit o the web. General optimism, in a mild and British sort of way. Raspberry Pi Ultrasound Sonar Range Sensing. SRF02 sensor. About the size of 20p. I’ll gloss over how sonar works to try to keep this article on topic, but Wikipedia has a good diagram of Active Sonar. And Devantech have a practical FAQ on using their modules. Enable the kernel modules ‘i2c bcm2708’ and ‘i2c dev’ by commenting out that line in /etc/modprobe.d/raspi-blacklist.conf. Once we’ve wired up our sensor, it should sho...

Homemade Salted Caramel and Honeycomb ice cream. Spring is finally here! Lambs are gambolling in the field, birds are tweeting and the sun is actually casting a shadow, so that means it’s time for another batch of ice cream. This isn’t the first time I’ve made salted caramel ice cream. You’ll need a handful of crushed up honeycomb.

Raspberry Pi Infrared Range Sensing | Dav's bit o the web
http://davstott.me.uk/index.php/2013/06/02/raspberry-pi-sharp-infrared
Dav's bit o the web. General optimism, in a mild and British sort of way. Raspberry Pi Infrared Range Sensing. The ultrasound range sensor I’m using has a minimum range of about 16cm, but I thought it would be interesting for my robot to sense objects more closely than that. Sharp have a range of three Infrared Range sensors. That are very popular and fairly easy to interface to a Raspberry Pi. I’ve chosen the GP2D120 because it’s got a supported range of 4cm to 30cm. As well as its rated minimum, typica...

Rivers of London, Ben Aaronovitch | Dav's bit o the web
http://davstott.me.uk/index.php/2014/02/08/rivers-of-london-ben-aaronovitch
Dav's bit o the web. General optimism, in a mild and British sort of way. Rivers of London, Ben Aaronovitch. Police action, personal adventure, old school magic, a smattering of romance, and a 1960s Jag driven over 100mph through central London make for a heady mix of science and magic in Rivers of London. This is Ben Aaronovitch. His universe has some simple and unique ideas that I think set it apart from other police procedural dramas, such a modern twist on elemental spirits and incorporating some int...

Digital cameras and memory card speeds | Dav's bit o the web

Dav's bit o the web. General optimism, in a mild and British sort of way. Digital cameras and memory card speeds. Digital cameras often have a rapid shoot mode, where they take still photographs as quickly as they can. I always thought that the maximum rate was limited by the camera’s internal hardware, but after reading Jeff Atwood’s comments on modern USB Flash drive performance. I wondered how significant the memory card’s speed is. Left: old and busted. Right: new hotness. Are generally rated as Clas...

Easy Caramel and Honeycomb Ice Cream | Dav's bit o the web
http://davstott.me.uk/index.php/2012/09/30/easy-caramel-and-honeycomb-ice-cream
Dav's bit o the web. General optimism, in a mild and British sort of way. Easy Caramel and Honeycomb Ice Cream. Salted Caramel and Honeycomb Ice Cream. This recipe was inspired by something I read in Olive Magazine earlier on this year, having half a can of Carnation Caramel spare was just the excuse I needed to get around to making it up. Easy isn’t always bad, though, this resulted in a very soft scoop and an intense, almost popcorn-like flavour that met with popular acclaim. Makes 500ml of ice cream.
