ham contest

On Thursday, April 3 at 5pm on KMUD, The SHARC Report will feature an interview with Southern Humboldt resident Frank Letton recorded on location at his high-performance Ham radio station perched on a mountaintop near his home in Whale Gulch. Frank competes against Hams all over the world using Morse code and only 5 watts of of transmitter power. Using his well-honed operating skills, top-notch radios and finely tuned, hand-made, high-gain antennas, Frank consistently scores among the very best in the nation in Ham radio contests. Tune in to learn more about Ham radio as a competitive sport this Thursday at 5pm, and listen to The SHARC Report, a program presented by the Southern Humboldt Amateur Radio Club, on the first Thursday of every month at 5pm on KMUD.

Circuit-Bending, a Fun Way to Learn About Electronics

This month the SHARC Report looks at Circuit-Bending, the art of rewiring battery powered electronic devices to exploit their hidden potential.  I just finished my first album of circuit-bent music titled Um… Uh… Gum Eh?

Tin Can Luminary is John Hardin (KI6DGX) and Amy Gustin.  Here is the back cover:

Here’s a couple of samples of the music on it:

I’ll be showing off some of my circuit-bent creations on Friday May 3rd from 5-9pm at the Hemp Connection in Garberville as part of Arts Alive.  Here’s a few of the devices I’ll bring out:

Here’s a few videos to help you make sense of the circuit-bent movement, and to get you started bending yourself:

Here’s Q Reed Ghazala’s piece, Hymn for the Faces of Belmez in it’s entirety:

Below is a good tutorial about how to add a pitch-bend knob to most electronic toys.    This is a very useful and easy modification:

The pitch resistor is usually labeled R1 on the circuit board.  You can also find the pitch resistor by touching it with your finger.  If the pitch of the toy changes when you touch it, you’ve got the right one.

Here’s the link to find the PAIA oscillator kit I described on the show:

For Dec. 2012, The SHARC Report Looks at PG&E’s New Smart Meters

For Dec. 2012, The SHARC Report Looks at PG&E’s New Smart Meters

electric-meter

This old-school electric meter relies on 19th century clockwork technology to meter electricity.  Not exactly “dumb” but by no means “hi-tech”

smartmeter-v01-pho

This is one of the new “smart meters” currently being installed by PG&E in Northern California.  These radio controlled devices provide no useful information to help customers make smart energy decisions, and they needlessly irradiate everything in their vicinity with microwave radiation.

Smart_meter italy

This is an Italian “smart meter”  they do not irradiate anyone, and they have a great feature to help customers make smart energy decisions called “in home metering” with a device like this:

Smart-meter--001

With in home real time energy monitoring, customers can see exactly how much energy they are using at any time, from the comfort of their indoor living space.  This feature is essential if “smart meters” are to help customers make smart energy choices.

Join me on Thursday Dec. 6 at 5pm on KMUD (www.kmud.org) for a discussion of this new application for radio technology.
