Power of the Daleks

February 26, 2009

I’ve been slowly working away on the Dalek – grabbing a few hours here and there. I’ve got the basic power distribution system in – unfortunately the drive system is 24v, and other parts need 12 and 6v. Rather than use wasteful linear regulators I put together some switching ones, using some free samples I […]

All in one..

February 24, 2009

New for 2011 – check out the MIDI Camera – gesture control with no Bluetooth, or even a PC! After my recent success with the Pixart camera from a WiiMote I thought I’d try and put everything on one board. Not quite as elegant as Mr Lee’s, but it works – this board will be […]

Pixart Sensor and Arduino

February 22, 2009

New for 2011 – check out the MIDI Camera – gesture control with no Bluetooth, or even a PC! I finally got round to desoldering a Pixart camera sensor from the front of WiiMote and hooking it up to the I2C bus of an Arduino. You need to run a 3.3v regulator, an LTC4301 buffer,  […]

Alien Robotic Death Machines…

January 25, 2009

Just got the Dalek dome reassembled before the weekend runs out. It’s a royal pain in the butt to put everything together and takes at least two people to do it. Uses C#, Xbee, Arduino, and Sabertooth motor controller.

Rotation Encoders…

January 20, 2009

…using magnets. I ordered 2-3 of these the other day. I thought that they might come in handy for the Dalek. Essentially the chip can tell the orientation of a magnetic field placed underneath it (ie. a magnet). So add a motor, arduino and motor controller, and hey presto – one seriously powerful continuous rotation […]

Sanguino!

January 20, 2009

As if the Arduino and all it’s clones weren’t enough I recently received a ‘Sanguino’ -  based around the larger ATMega644P processor. It took a little longer than expected to assemble, for some reason the solder did not want to flow onto the pads on the reverse side of the board. For a while I […]

Pete’s Quick Hyperbaric Spark Gap ™

September 10, 2008

Pete put together this pressurized static spark gap – the results are some of the best we’ve seen so far.

Adjusting the phase on a synchronous rotary spark gap

September 10, 2008

This footage shows the advantage of having a phase controller for the synchronous motor. Using the dial we can alter the phase relationship of the motor until it dials in exactly with the up and down swing of the AC supply.

First Tesla coil test footage

August 15, 2008

We managed to get some footage of the tesla coil running last night, just before we switched over from a static gap to a rotary gap. It looks like the rotor is not quite in sync with the up and down swing of the AC line voltage. So that’s the next thing to fix.

Tesla Coil

July 28, 2008

We did the final assemble and checks on our Tesla coil on Saturday night, we rolled it out into the back yard and switched it on… Nothing is as scary as that first time… And… Nothing exploded, imploded, melted, smoked or fried… We were able to tease 7″ sparks out of the toroid with the […]
