  • Sensing Nerf darts

    If you’re going to build a foam dart range, then at some point you’re going to have to build a some kind of sensor to be able to register the hits at the target. When we originally started this (with MFUKLC), we started by looking around at what other people...

  • Unbricking a Pro-Micro board

    I had a little trouble first setting up the Arduino compatible Pro Micro board in Ubuntu, but with that little hiccup out of the way, it’s been a very useful board to have. The small size and around £5 price for clones on ebay means it’s cheap and small enough...

  • Sparkfun Pro Micro serial device busy

    When I first started using them, I did have a little trouble uploading code to the Sparkfun Pro Micro, under Ubuntu 14.04LTS, using the Arduino IDE 1.6.8. The Pro Micro board definitions were installed as detailed in the Sparkfun guide for linux but the board just gave the same error...

  • A Small Egg

    On the contrary to what little has been said already about this particular endeavour, the egg in question is actually on the rather large side. Andrew Small’s comissioned piece “Egg Untitled” is a specifically designed installation involving an aluminium subframe which holds 30 dimmable led lights, wifi, controllers and 219...

  • Can you feel the breeze? The “Breath Of Air” Kites

    So still and serene are the Kites. A delicate design hanging from a sturdy structure, that with just a gentle movement of air turn into a dancing delight.
