Solar Cricket – finally, I get to build something…

September 13, 2013

It’s been a busy year so far – lots of stuff going on, and precious little time to build anything. A couple of months ago however I was asked by my buddies at MAKE magazine to put together an interesting little project. A solar powered chirping cricket – that uses solar energy to maintain the […]

Finally cutting something out

December 6, 2012

Built the enclosure, and hooked up fume extraction and air assist… This is cutting 1/8″ plastic – everything seems to work just fine – 3 passes and the pieces just drop right out. The cutting residue washes off with soap and water. UPDATE : I was looking for tips on identifying laser safe plastics and […]

Wow, been a long time since I posted about anything. I thought it was about time I wrote about something new. I recently acquired all the parts for a laser cutter – although I was running an 80W tube from the BlackToe gantry I found that the two machining techniques were at odds with each […]

…custom electronic workbench

June 26, 2012

I’d been using an old dining table as a workbench for a long time – and it just wasn’t working out. The cables for all the test equipment kept getting tangled up, and it was too deep to be an efficient use of space. 20 minutes in to any project and it was a mess… […]

…Orbital Spex for under a tenner (dollars that is…)

March 10, 2012

Sure, you can buy those centrally-located LED miner’s lamps, but nothing says 90’s geek chic like your very own Orbital glasses. Now you can recreate those halcyon (harr harr) days of almost pitch black gig-ness (“When do Orbital come on?” – “They’ve been playing for the last 10 minutes”) I needed a pair of these […]

…infringing patents (probably)

I’ve been meaning to build one of these for ages. Can anyone guess what it is? It’s not a Taser, or one of those shocking buzzer things – the clue is that the coils are well “potted” and have very different gauges of wire. Answers on a postcard please, or in the comments… UPDATE : […]

…Treasure Finder for MAKE:Projects

This was my favo[u]rite of all the MAKE projects I’ve been working on. This project uses 2 oscillators in a configuration very much like a Theremin to create a beat frequency (BFO) metal detector. Range is a few inches for the smaller detection coil, but the detection range can be increased by adding a larger […]

…Fritz Lang’s Theremin Stand

(Sounds like something you’d find in Warehouse 13) For many weeks I’ve been trying to come up with a cabinet design for the vacuüm tube Theremin I built a while ago. I decided that the electronics were far too marvelous to hide away in the classic RCA “drinks cabinet” – and that something more radical […]

Fry’s – now dealin ‘duinos…

November 6, 2011

Wow, didn’t expect that. I was lurkin’ in my local Fry’s and found a section full of Arduino clones… They seem to have a range (from Megas to Nanos) of them – prices are pretty good too.

Air Guitar? …meet Air Piano

My buddy John Claeys sent me a link to this video of the AirPiano device being demonstrated by Jo Hamilton. I’ve not been able to find out too much about the design or origins of the instrument. It seems to use optical proximity sensing to detect the player’s hands. A neat idea, and a slick […]
