I have finally gotten around to documenting my Arduino powered laser show that uses audio speakers for Galvos.
Full documentation and source code is available via this Instructable.
Quite happy with the way it works now:
The “home” for this project (and it’s Twitter … (read more)
Find out how to build your own peltier cloud chamber here:

Turns out my new Thorite sample emits a fair amount of Radon 220 (aka Thoron)…… (read more)
Recently did an interview for BBC’s Outriders radio show / podcast:
http://www.bbc.co.uk/blogs/outriders/2011/12/creators.shtml
Topics include cloud chambers, my Resistor Photo ID iPhone app and tinkering in general.
Jamillah Knowles did a great job putting this together! I came out sounding far more coherent than I … (read more)
(Note: Due to changes in iOS – this app is no longer available… sorry!)
I shipped a new iPhone app a few weeks ago – “Resistor Photo ID”
It uses your iPhone’s camera to help identify resistor values.
I’ve been playing with Autodesk’s 123D “Catch”
It’s a free app that transforms sequences of still images into a 3d model of an object.
Here’s a sample video I did:
It does the processing “in the cloud” – in conjunction with a client-side application.… (read more)
Back from showing off the Electronic Cloud Chamber at Maker Faire NYC – things went very well!
I managed to score three “Editor’s Choice” blue ribbons for the exhibit!
People really liked that the project is both “open source” (how to build your own … (read more)
In early August I took a tour of the Hanford Site located near Richland, Washington.
Hanford was created in 1943 to produce plutonium for nuclear bombs. Operating until the late 80’s – its 9 nuclear reactors produced enough material for 60,000 weapons.
The tour encompassed … (read more)
Over the last year – I’ve toyed with the notion of making an EDF fan bike.
I finally got around to putting one together – here’s some test footage:
EDF is short for Electric Ducted Fan. They are basically enclosed propellers for model airplanes – … (read more)
Been enjoying my new Full Spectrum laser cutter. It’s a lot of laser cutter for $2500!
I wanted to come up with something better than the stock “aiming” laser pointer.
Issue is that since the stock aiming laser doesn’t actually follow the cutting … (read more)
Nothing Labs now has a laser cutter!
The Full Spectrum 40 Watt Laser Cutter showed up about a week ago.
Here’s a video documenting my experience thus far:
Highs:
– It works pretty well!
– Deluxe package really includes everything you need to start cutting … (read more)
I just did another Instructable – Easy, Reversible Motor Control for Arduino (or any Microcontroller) (wow – that’s a mouthful…).
It is the result of my effort to come up with something less annoying to construct than an H-Bridge – using just locally available parts … (read more)
This project is a variation of my arduino powered laser show – and honestly it’s not quite as cool. But – I wanted to go down this road to explore a few ideas…
The video really covers all the core technical details:
My original hope … (read more)
