This is a homemade 4-tube (including CRT) oscilloscope clock. The oscilloscope uses a 6BC7 for the power supply and a pair of 6AU6 pentodes for the XY deflection amplifiers. A PIC 16F876 with a DAC generates the XY signals to draw the clock on the 2AP1 (2-inch) CRT.
This video shows vector lines being drawn rapidly on the 1978 Tektronix 4052 graphics system computer, which is like an old fashioned way to create a screensaver. In the beginning of the video I'm running through the whole program for a quick review before typing in RUN.

This is a single digit numitron clock using a PIC 16F84 that displays the time in HH:MM format. If the tens of hours is 0 then it is skipped and not displayed.
ASL video based on a funny story called "Engineering Analysis of Santa Claus" found online. There are some slight mistakes and minor changes in the story because it was all told from memory. Also you'll have to excuse the slight English sign "accents" in the video.
This is an additional video to supplement my first "Analog Oscilloscope Pong" video. The ball is set at the minimum X and Y speeds the analog circuit would allow. DC coupling to the oscilloscope produces a crisp and stable picture, while AC coupling makes the picture drift around as the ball changes position, which adds to the fun and challenge.
This is the first half (no audio) of all the go-carting clips I compiled. Please view the second half after this one because I could not fit the whole video in a single uploadable file.
The clips are mostly of me go-carting at my friend Darlene's farm.
This was the first prize winner for the Technology Challenge at the 2006 TSA nationals competition. Goal is basically to keep a billard ball rolling, do various (pointless) things like deploying the umbrella and spray over it, pull the flag up, blow on it with a fan, then ring the bell at exactly 90 seconds. Oh, and it says "That was easy" in the end.
An all automatic pneumatic can crusher. The can is placed in the "crushing chamber" and a pneumatic pushbutton on the right of the conveyor belt activates the machine, then the camshafts take over the timing of each pneumatic device. The crusher shuts off by itself when done crushing a can. No electronics or computer control!

This is a single digit VFD tube clock using a PIC 16F84 that displays the time in HH:MM format. If the tens of hours is 0 then it is skipped and not displayed.
