I'm thinking that electrical noise may be the culprit. Right now, I'm leaning towards a noisy switch or outlet, though it could still be an appliance. Have you had a chance to test it yet?

Need help with circuit
Thank you, I've read it. Unfortunately, the way I read it is that a 4x4 matrix needs 17 pins. By my calculations, an 8x16 would need at least 33. Is that correct? I've never worked with a led matrix before so be kind, lol.
Need help with circuit
I understand that a MAX6954 can drive 128 discreet led's. What I can't understand is how to connect this chip to a matrix of 8x16 discreet leds and use the internal fonts on the chip to scroll. Can anyone throw me a bone? Thank you in advance!

Oscillating weights
In short, the answer is yes. The basic principle was applied to wave action and is currently under study. It could also be applied to tall structures such as towers and skyscrapers (and even trees). The only limitations are practical ones. Harvesting the energy is another...
