This Month on The SHARC Report, Linda Nellist talks about CERT Training



KMUD Airs Preview of Upcoming Disaster Prep Workshop

On Thursday March 7 at 5pm, KMUD and The Southern Humboldt Amateur Radio Club present The SHARC Report. This month the program features an interview with Linda Nellist, who will lead a CERT training workshop in the Whitethorn area on Friday-Sunday, March 8-10. Linda will talk about the workshop, which involves 23 hours of instruction, covering disaster preparedness, earthquake, tsunami, flood and fire hazards, medical operations and triage, among other topics. The training includes a full disaster simulation drill, and participants will receive a backpack full of safety equipment. Ordinarily the course fee is $150 dollars, but because of generous donations Southern Humboldt residents can take the course at no charge. To sign up for the CERT training workshop, call Judy Warren at 499-0754, Kent Griggsmiller at 986-7416 or Susie Fox at 986-7314. Tune in to The SHARC Report on the first Thursday of every month at 5pm on KMUD.

The Return of Circuit-Bending

The Return of Circuit Bending

So I didn’t tell you about our circuit bending workshop. I mean, I told you it was coming, plenty of times, but I didn’t tell you how it went. Well, it went swimmingly! We had a great turnout, more than I expected. My only regret was that with so many people in the workshop, building kits took the entire time, and CMKT4 didn’t get a chance to play.

CMKT4, who gave up their only day off on their 30 day West Coast tour, to do this workshop in G,ville, told me that our event turned out to be their highest grossing workshop on the entire tour. They had a great time at the event as well, and look forward to returning to Garberville soon. Next time, we’ll get started earlier and go later.

I had a terrific time! I met some cool new people, got to know some people I already knew better, and got to introduce some of my Ham friends to some of my music friends. I also got to stalk our local thrift stores with CMKT4 and ask some circuit bending questions of someone who knows their way around the insides of a Casio mini-keyboard.

I also got to build this spiffy cigar box drum machine. I love the sound. It reminds me of 50s sci-fi movies.


The box contains three piezoelectric contact microphones (probably overkill). The underside has three different sized expansion springs for reverb. Above board you can see a collection of soft drink lids, beer bottle caps, finger cymbals, a small brass bell, five different sized compression springs and two small wire chimes surgically removed from little plush toys.

I grabbed one of those little PAIA two transistor oscillator kits that SHARC was giving away at the event,

took it home and built this little light-controlled, Theremin-like instrument. I housed the project in a burned out solar yard light.


Since this oscillator runs on only one and a half volts, the single AAA battery holder in the yard light provided the power solution. I removed the LED, circuit board and solar panel from the lamp, replacing them with the oscillator circuit card and five photo-resistors wired in series, routing various wires through the hole that originally accommodated the LED. I found a speaker that fit perfectly into an old spray paint can lid, and mounted it to the bottom of the lamp with aluminum angle brackets I cut from an aluminum can. I mounted a momentary action switch, and an output jack in the lamp flange. The switch turns the oscillator on and off, the amount of light coming in the top controls the pitch.

I really hope everyone else who participated in the event had as much fun as I did. I hope CMKT4 will return to Garberville as soon as this Fall and we can have another circuit-bending event, and next time we’ll have some music, maybe including some local circuit-benders.

SHARC Report for May 3 Features Interview with CMKT4 Member Zach Adams

The SHARC Report Talks Circuit Bending With Zach Adams of CMKT4 on KMUD

On Thursday, May 3 at 5pm on KMUD, The SHARC Report will present an interview with Zach Adams of the Dekalb, Ill based circuit bending band, CMKT4. In the interview, Adams talks about circuit bending, the DIY electronics workshops they teach, and his band’s upcoming West Coast tour, which will bring them to the Garberville Veterans Hall on Monday May 21st, and to the Ink People’s Annex in Arcata on Tuesday May 22.

Circuit bending, or hardware hacking, involves rewiring electronic circuits to exploit their untapped potential. CMKT4 uses a number of circuit-bent instruments in their music, ranging from rewired sound modules from talking stuffed animals, to educational electronic toys, to modified synthesizers and fuzz boxes, to make their music.

Besides playing circuit-bent music, the band makes and markets electronic kits for circuit-benders and musicians who want to build their own equipment. They also host workshops to teach the skills and inspire the imagination to do it. CMKT4 will lead hands-on circuit bending and electronic kit building workshops at both the upcoming Garberville and Arcata events. The Southern Humboldt Amateur Radio Club, or SHARC presents this radio interview, and upcoming Garberville CMKT4 event to encourage people to have fun with electronics, safely.

SHARC offers a Technician-Class Ham license prep course that covers basic electronics, and Hams are a great resource for anyone who likes to play with soldering pencils and circuit boards. Call Jack Foster at 923 3700 for more info about the Technician-Class license prep class or about the upcoming CMKT4 event.
