TMaker Faire Bay Area 2014

The 2014 Maker Faire Bay Area will take place in San Mateo, CA this coming weekend, May 17-18th.  I’ll be there! No booth this time. I’ll be wandering around the fairgrounds hoping to actually see the Faire this year.

Open Hardware Summit 2013

What an awesome event.  Great people, great talks, and gorgeous weather made for an epic weekend in Cambridge.

My photos are up on flickr.

Also, I just finished recording a shiny new episode of The Amp Hour, which should be online as soon as Chris finishes editing.  Look for it later tonight or tomorrow on Tuesday.

Upcoming events: OHS, TAPR DCC, NYMF

There are three major events of interest to open source hardware and makery folks this month:

I’ll be at OHS and TAPR, but have to skip the NY Maker Faire this year.  I imagine that far fewer folks from OHS will be attending NYMF now that those events are no longer co-located.

Sorry NYMF, but I can’t turn down an excuse to visit my friends in Harvard square.

The Seattle Mini Maker Faire is next weekend!

Sunday, June 2nd, 2013


The 2nd(?) annual Seattle Mini Maker Faire will take place next weekend (June 8th-9th, 2013) in the Northwest Rooms at the Seattle Center.

I’ll be there showing off my Glowy Geiger Chimes and selling open source Geiger counter kitsAlan is bringing his Glowputer, and many other Seattle-area makers will be there (here’s a list).

See you there!

It’s that time of the year again! The 2013 Maker Faire Bay Area is next weekend (May 18-19th) in San Mateo, California.

I haven’t had time to post about it, but over the past few weeks I’ve been busy working on a special project for the Maker Faire this year.

This year I am bringing a new and improved version of the “Geiger counter-powered ambient music thing” that I threw together at the last minute last year (and never really came up with a good name for). In that project, I connected five of my open source Geiger Counter kits to an Arduino that sent MIDI commands to a Sparkfun Music Instrument Shield. When each Geiger counter was triggered by background radiation or one of the weakly radioactive sources nearby, the Arduino would send a command to the shield to play a musical note.

This year I’m bringing a new and improved version that uses a new piece of hardware that I designed specifically for the Faire – the Geiger Pad.

Each Geiger Pad contains a fully functional Geiger Counter based on my Geiger counter kit. The output of the Geiger counter is connected to a cluster of 14 very bright 5mm UV LEDs. On top of the Pad is a petri dish filled with uranium marbles. Each time the Geiger counter detects that a gamma ray was emitted by the marbles, it flashes the UV LEDs. Since the uranium marbles fluoresce green under UV light, this produces a brilliant green glow.

Today (yes, once again at the last minute) I finally got all the pieces together and working. If you come to the Faire you’ll be able to see it in person, but I also posted a short video on flickr:

The Maker Faire website lists me in Expo Hall, but it’s more likely that I’ll be somewhere in the dark area of Fiesta Hall instead. Check the Maker Faire website later in the week for more details.

See you at the Faire!
