Buzzing Dimmer Switch

The dimmer switch on my living room wall occasionally makes an annoying buzzing sound. I figured-out how to solve the problem using a small magnet.

Most dimmer switches contain an inductor wound on top of an iron or ferrite core. This coil acts as a "choke", to smooth the pulses of current generated by the dimmer circuitry. The buzzing sound comes from the bucking of the magnetic field in the choke coil. There must be some ferromagnetic materials in the switch and its housing that become slightly magnetized over time and vibrate in sympathy with the pulsed inductor.

I found that I can eliminate the buzz by passing a magnet near one of the screws. I used a segment from one of those "ball and stick" magnetic model kits, which is a small but strong rare-earth magnet (probably neodymium). The small magnetic bias inside the switch is disrupted by the magnet, and it falls silent. If the buzz returns, I just bring a magnet up to the switch again, touch it to the bottom screw, and *presto*, the noise is gone!

Dead Kids 2

Dead Kids 2 - Director's Cut hits the net today.

Dead Kids 2 was shot on location in Galesburg, Il in 1996. Responding to the cult classic psychological thriller ca. 1981, "Dead Kids", aka, "Strange Behavior"; set in the Illinois college town of Galesburg, (but was filmed in New Zealand)... Independent artists Cyrus Khazai and Eric Andersen recruited their friends to help produce the unauthorized sequel. Armed with an 8mm video camcorder, a DAT recorder, and a budget of about $100, Khazai and Andersen produced a full feature length video movie which continues the storyline set forth in the original. Ultra-campy and strangely disturbing, the sequel amusingly recycles the iconic imagery of the Michael Laughlin original.

This version is slightly cut down from a damaged copy of the original release, and a few basic effects were added.
