  • PCB Design:
  • Software Design:
  • Circuit Design:
  • Mechanical Design:
  • Design and Layout of a power supplys:
  • Design and layout of a PIC based controllers:


  • Current and past Projects



  • Tectivity
  • Tectivity had me design a 3 channel LED controller.
    Each channel had 2.3 amp of drive capability.
    You can adjust each channels current from 0 to 2.3 amps.
    The LED controller is used for a flash for machine vision systems.
    There was also 3 LED boards that can be used with the LED controller for different applications.


  • Mectron
  • I have done a variety of projects for Mectron.
    I helped design a plasma treatment system that they got a patent for.
    Designed a 3 channel LED controller for their qualifier.
    Worked on a number of LED light rings and light bars.
    Currently working on eddy current controller and replacing there wire wound coils with PCB coils.


  • Alarm System
  • A customer wanted a custom alarm system designed and installed in their house.
    I used a custom designed board for monitoring doors and windows and other stuff.
    Wrote an APP to run on a laptop to control every thing.
    I monitor the house power and sump pump.
    All windows and doors are monitored.
    It is all battey backed up.


  • Thermostat
  • I designed this Thermostat for a customer that wanted to control and setup the
    Thermostat from a PC and have an APP on the PC to setup and manage the Thermostat.


  • Ballon Launch from Kewanee Illonoias
  • I started working on this project in June of 2007.
    I have had this idea for 20 years but one day I was reading
    my Nuts and Volts magazine and they had an article about near space.
    This is what started me on this project.


  • Somerset Beach Balloon Testing
  • I did some testing after the first flight to figure out some of the problems.
    Here are the pictures from the Sumerset Beach testing.


  • Great Plains Space Launch
  • My second balloon flight was with a group GPSL (Great Planes Space Launch).
    Paul and I went to Hutchinson Kansas for a 3 day conference.
    The last day we where there the GPSL group launched about 12 balloons.
    We launched my balloon and the flight lasted about hour and a half and landed in a field about 15 miles away.
    We tracked it for just about the whole time.


  • My Cube Satelite Design
  • I started phase 3 of my balloon project.
    I used a standard Cubesat format. 100 mm by 100 mm.
    I was able to put all the cameras and electronics in that format.
    I had the frame 3 D printed.


  • Mectron Patent
  • The Plasma Treatment System was designed for heating gold nano spheres in a tumor to kill the cells.
    It can all so be used for wound healing by killing off infected dead skin cells.
    Another use is to clean seeds to increases the wetability so they will germinate quicker.


  • Xitron
  • Xitron wanted an interface board designed to connect and control external devices.
    The interface board is used to read belt speed by reading pulses form an rotary optical encoder.
    The interface board passes and count Top of Form signal from a sensor to the HP PCA controller.
    The interface board can control belt speed, feed on/off, vacuum on/off, and turn aerosol fan on/off.
    The connection between the interface board and the Xitron PC can be either USB or serial.
    Built a test fixture and wrote a test procedure so that Lectronics the PCB assembly house could test the board.
