I design and make waterski timers for tournaments. 15 second timers for barefoot waterski tournaments. 20 second timers for traditional ski trick timing.
For barefoot waterskiing I make both a simple handheld timer (single button) as well as a majority timer (3 buttons, time starts when two have been pressed, i.e. when the majority of judges agree time should start).
For slalom skiers I make 3D printed wing angle gauges for setting the fin wing angle accurately. You can print them yourself for free or buy a set.
I also do computer consulting for both Windows and Macintosh computers.
Electronic design and repair, 3D design and printing, laser engraving, CNC machining and welding services are also available.
