Code for Cubic Bezier Version
Log from Fitting a Quadratic Bezier Curve to Point Data
Cubic Code Results While the results are good it is not exact like the piece-wise quadratic bezier code.I quess a fourth order bezier would bit better.Hers is the cubic match:Note the bezier cuves are too wide just aft of the maxium beam and too...

Unbiased Testing
Log from TritiLED
The tests I've done so far have indicated that there's something to be gained with pulsed LEDs for efficient glow markers, but the simple by-eye evaluation of relative brightness between the DC-driven and pulsed LEDs may not be very accurate. I've been...

TMC5160 motion controller mode
Log from DIY Polarimetric Camera
The Trinamic TMC5160 has a motion controller mode which is very cool. It allows you to set things like acceleration parameters, destination, speed via SPI, instead of using the STEP / DIR pins. I have been using the TMC5160 SilentStepStick as a board...

Measuring video latency with an Arduino
Log from Stereo Ninja
For Stereo Ninja testing we need an easy way to measure latency. A simple way is to put a smart phone with a stopwatch app in front of the camera and then take a photo with both the smart phone and the monitor displaying the smart phone on it. Then simply...
