This is the raw MP4 format. Better lighting and color quality. Something gets lost in the conversion from MP4 to AVI. So here's the source.
Apparently one of my office mates is a very competitive sort. So I have to pull a fast one on him. I setup my Arduino to pulse pin 13 ever 10ms. I then took that output and put it across the magnetic reed switch on the pedometer. I know, I know, I could have done a magnetic coil but what's the fun in that?
Mitch Altman was in town and he showed us how to make the Trippy RGB out of the MiniPOV controller. I had to further modify since the green LED I had wasn't bright enough.
In this part we test the BBB with both USB power and an external 5V 30ma source. Works fine on both. And I'm loving the HY1803D power supply. Now I have to get barrel connectors so I can power the Arduino from it too.
Discrete components
So I load the sample LED fader that uses on of the PWM ports and I hooked it up to my Oscilloscope and show the PWM wave form.
So this would rock as a keyer for Morse Code. You can vary all the timing elements with simple variables that could use pots to set.Right now it sends in light pulses, but it could just as well do sound via PWM ports, or even drive a keying circuit.
Since early Christians hijacked the Roman celebration of the god Saturn, I think it's appropraite to use that name again.
So now I have a collection of items that might do something useful someday. A Diecimila, a Bare Bones Board (An Arduino Clone), an 8x8 bicolor LED matrix, and a 343MHz 2400bps radio transmitter and receiver.
