Professionally

These projects were completed as part of my consulting business. These are actual projects working for actual companies.

Battery Charge Monitor

Monitors the voltage of a battery as it charges and automatically switches from fast charge to trickle charge once the battery voltage has reached the proper charge voltage. After eight hours the charger is stopped to prevent cooking the battery.

Machine Production Monitor

The client needed to monitor the number of times their nipple machines cycles while producing the parts. The information is both presented to the machine operator through an
HMI and also networked back to a central server via a CAN system.
Finally, the cycle information is merged into their AS/400 payroll
system.

Hobby

These projects, on the other hand, are projects I’ve done for either friends or myself.

PICtach

Designed a PIC based tachometer for my car. Unfortunately, I never completed the project, so this is more a proof-of-concept. The code to drive the LEDs and generate the correct display values works, but I never wrote code to actually integrate the tachometer into my car. (I got a new car with a built in tach, so the project was abandoned as
other projects came due.)
