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!

Come see my Glowy Geiger Chimes at the 2013 Maker Faire Bay Area!

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!

My Hardware/Maker/Arcade/Pinball Geeky Events Calendar 2013

April 21st, 2013 by Jeff

It’s officially event season!  I was sorting through my calendar this afternoon and I thought I’d share a few geeky hardware/arcade/pinball/open source/hackercamp events that I’m looking forward to over the next few months.

April 22-25: DESIGN West, San Jose, CA.  I’ll be there.  Joe Grand is speaking on Wednesday

May 18-19: Maker Faire Bay Area, San Mateo, CA.  I’ll be there with a booth this year (Glowy Geiger Chimes).

May 17-19: Dayton Hamvention, Dayton, OH.  I want to check out this HUGE ham radio event sometime, but my attempt to go to Dayton this year was thwarted because, yet again, it falls on the same weekend as the Maker Faire.  Maybe next year.

June 2-7: MTT IMS 2013, Seattle, WA – Expo is free on Wednesday

June 7-9: Northwest Pinball and Arcade Show (NWPAS), Tacoma, WA.  Definitely checking out this local show this year.

June 8-9: Seattle Mini Maker Faire, Seattle, WA  (Another geek event collision, this time in Seattle.)

June 22-23: ARRL Field Day

July 13-14: California Extreme (CAX), Santa Clara, CA.  This might be my first year at CAX, if I don’t have to cancel at the last minute like last year!

July 31-Aug 4: OHM2013, Geestmerambacht, NL.  Deadline to submit a talk is May 1st.

Sept. 6: Open Hardware Summit, MIT (1st year held separately from the World Maker Faire!)

Sept. 21-22: World Maker Faire, Queens, NY.

Did I miss anything?  What other events are folks excited about?

HSC Santa Rosa closing on May 4th, Closeout Sale starts April 27

April 19th, 2013 by Jeff

HSC Santa Rosa (actually Rohnert Park) is closing their doors on May 4th. They are having a closeout sale that begins next weekend (April 27th) and runs through the 1st week of May.

I visited this small but convenient Halted branch often while I worked in Santa Rosa, and I’m sad to hear this news. Fortunately, I’ll be in the area next week and will have one last chance to visit before the store closes. (Unfortunately, I’m traveling by air, so I won’t be able to bring too much surplus junk back home.)

HSC closed their Sacramento store in 2007. With Rohnert Park closing next month, the original Santa Clara location will be the only one remaining.

More details below.

Special Announcement

Attention HSC Customers:

After 27 years in the Santa Rosa area, HSC Electronic Supply of Rohnert Park is closing its doors for good on May 4, 2013. Halted Specialties Co. Inc. will continue to operate its main store, HSC Electronic Supply of Santa Clara.

Store Closing Sale!

Rohnert Park Location Only.

Storewide Liquidation!

20% to 80% Off Entire Stock.

Saturday, April 27th to Saturday, May 4th

Our shelves are spilling over in Santa Clara so we’d rather blow it out than truck it back to support on-going Santa Clara operations. Please stop by to check out this last opportunity for deals in Rohnert Park and stop by our Santa Clara store when visiting Silicon Valley. Don’t forget to visit us at www.halted.com as well.

Thank You,

HSC Management
