Projects
-
generated svg diagrams showing track resistance with multiple feeders
- trkSvg/tgrSvg.k scripts for generating .svg track drawings and diagrams
- created this website using github
- scripts to print coal trestle bents
- scripts to print loading docks
- modifed cardboard freight house
-
manual reverser dwarf signal circuit
- remotored Boxcab
- found nylon worm that mates with axle gear .. mod
- learned that coefficients for RPM/V and mN/A are equal and
provide the means to identify if a motor is suitable.
Also determined that ~9mN of torque is appropriate
- Arduino Mega DCC command station, motor shield
- generic DCC controller using
- ESP32 supporting WiFi
- RS-485
- OLED display
- commercial 4x4 keypad
- accelerometer, 3V battery and java display
