my first slice of home laser cutting action! Here is the x and y axis ready to be installed. The motors and controllers are done, the laser is on its way – watch this space!

I’m working with Martina Sprenghart (fashion photographer) to produce an installation for her latest work.
The exhibition is in in the Mall Galleries: 17 Carlton House Terrace, London, SW1Y 5BD http://www.mallgalleries.org.

I’ve been working on the wiimote -> puredata -> bluemelon controlled gas organ for a while now, and we are getting ready for a full test on Monday.
We have a big event called ‘flame and flesh’ happening on the 22nd February at Corsica Studios. Come along and check it out!
update!
the test went really well! We have good intuitive control of the organ using 2 wiimotes. I’ve also got a basic random mode going down too. It was great seeing Shawn dancing with the controllers because the sound was so well linked to his movement. I began to be able to recognise and predict what the sound was going to do as he moved. I think the use of wiimotes is going to really make waves in synchronising music, movement, visuals and who knows what else. Exciting!
A computer controlled tubular bell.
Features
- beautiful tone,
- the tubular bell can be any length (note) or colour. This version is A at 220Hz (1.28m long)
- custom designs could feature multiple bells
- I can provide easy to use Linux drivers and I’m sure Windows would be just as easy. You just write a command to the parallel port,
- supplied with C source code, easy to customize
If you want one, I build them for £100 plus the tubular bell. The bell is more expensive the bigger it gets, and colours (anodized) cost more. £150 gets you the ringer and a concert A (120cm) tube. Stand not included, but its easy to hang from the ceiling or a wall.
I can also make the top boards from different materials (wood, aluminium, perspex) and hide the circuitry if desired.
How it works
A motor (pwm controlled) is used to wind up the arm and then a magnet on the arm sticks to the end of the solenoid. When the solenoid is switched on, it pulls the piston back, breaking the connection with the magnet. As the arm swings down, the motor unravels the string to make the movement as free as possible. The motor keeps running to wind the beater back up (to avoid damping the bell). A microswitch detects that the arm is back, and the motor unwinds gently to allow the solenoid plunger down gently (too much of a jolt and the arm breaks free).
