Dude, Where’s My… Bus? A 3D-printed bus tracker housing a Raspberry Pi

by  •  • 0 Comments

Over at DesignSpark, Dr Lucy Rogers has written a great tutorial which fuses the Raspberry Pi, 3D printing, an ESP8266 module and some Neopixels into a bus warning system. The system has the following features:

  • A visual alert to tell you to leave for the bus stop – and your bus will miraculously arrive just after you do.
  • #WhereIsMyBus will also warn you if there are no buses running, so you can make other plans.
  • And if that isn’t enough, when it is not in use as a bus alert, it becomes a #Cheerlights light.

It uses a combination of Arduino code and Lucy’s favourite language NodeRED. You can download all the files you need (including the 3D printing files for the bus itself) and read the tutorial here.

Mexican bacteriological experiment produces biology-driven music via a Raspberry Pi

by  •  • 0 Comments

A Mexican team of Paloma López, Leslie García, and Emmanuel Anguiano (together, they are known as Interspecifics) have created a nature-driven musical instrument. Micro-ritmos is an art installation in which ‘music’ is generated by patterns formed by bacterial cells. The material is called Geobacter, which is an anaerobic bacteria found in sediment. All the code for the experiment can be found here. The comments are in Spanish, but careful use of Google Translate can help there.

The hardware is based around a Raspberry Pi B+ and camera module with an Arduino. The music synthesis is done by SuperCollider. The bacteria triggers lights to be activated and variations in the cells produce patterns. The Python program ‘learns’ as the patterns are watched and that information is sent into the synthesizer. It’s live coding created by a biological process.

You can see a video of it in action above. The subtitles are in Spanish.

Creating a piece of Raspberry Pi powered Neopixel light furniture

by  •  • 0 Comments

James Poole has taken a string of Neopixels (UK/USA) and hooked it up to an Arduino. He’s then taken a Raspberry Pi and used it to control the Arduino via a web interface. James then mounted the whole lot on a block of wood and a metal strip to turn it into a rough piece of furniture. Much blinkiness, and he’s uploaded all the code so you can try it out yourself. Read more over at his blog and checkout the code here.

Andy Baker and Andrew Oakley are running the next installment of the Cotswold Raspberry Jam on Saturday, 26th November. The event runs from 1-4pm at University of Gloucester Park Campus in Cheltenham and will feature talks, show and tell and workshops/tutorials. There are even still some tickets left for the workshops, so snap them up quick. Well worth attending if you’re in the area (or even if you’re not!) – it’s been going a while and they do a great event by all accounts. Free tickets are available from the Cotswold Jam website.
