Some new projects 2016-2020

Here are finally some new projects 2016 - 2020. To come see below on this web page.

• An inverted pendulum on a chart with computer controlled PID-regulator (latest update: 2019-03-16) New!
  Somewhat modified the software also works as a drive for low speed DC servo motors with encoder.
  However some details still must be improved. Some images and videos are now available. Software
  download, documentation and schematics will come.
  

• A homemade and computer controlled pen plotter/milling machine based on a treadmill with stepper motors (latest update: 2018-06-07)
  Now comes with stepper motor software (for the digital PCI-DIO024 I/O board and the Velleman K8055
  USB I/O board) to plot or mill a spiral, a Dragon curve, Lorenz attractor and a cocoon curve.
  

• A very good LED stroboscope (based on Elektor.com July 2012) (latest update: 2016-02-02)

Hi-Fi amplifiers, stereo and audio systems

• Some thoughts about home stereo systems (latest update: 2009-06-22)

Electro-mechanics, inverted pendulums, electric motors and controllers

• A very simple and cheap computer controlled "inverted pendulum" with PID-regulator software (latest update: 2009-08-29)

• Digital PWM-drivers and PI-regulator software for electric DC motors (latest update: 2008-11-12)

• Some power PWM-drivers for electric DC motors (latest update: 2007-06-03)

Other electronics projects and power supplies

• Automatic charger and discharger for small lead accumulators (and Li-ion batteries) (latest update: 2010-02-02)

• Power supply 2 - 30 V (> 24 V at max 15 A) stabilized (latest update: 2008-09-04)

• Power supply 13.8 V 4.4 A stabilized with over voltage protection (latest update: 2008-06-23)

• An electronic tuning fork at A 440 Hz (latest update: 2004-10-05)

• Two Sinus Generators (latest update: 2004-01-25)

• A simple glow plug driver for model engines (latest update: 1998-04-08)
