Introduction In 2004 I finally had to purchase another car since my old boat (a 1980 Oldsmobile Cutlass Supreme) had finally bitten the dust. I looked around and found a 1997 manual 5-speed Chevy Cavalier. Great. It had been a while since I had driven a stick-shift, but I looked forward to it. One problem though: no tach. Now, I don’t actually need a tach to drive stick, but it’s sure nice to have.
Introduction A local manufacturing company contracted me to develop a battery charger monitor. Their forklifts are all battery operated, so they are constantly charging these batteries. Unfortunately, their existing battery charger did not include a means of monitoring the voltage going into the batteries, so they often overcharged and cooked the batteries. Not good. The device I developed monitors the battery’s voltage and when it reaches the “charged” limit automatically switches the charge into trickle charge mode.
Introduction I was asked by a local manufacturing company to come in and help them retrieve production information from a department of nipple machines. The production information is gathered in real-time before being integrated into their existing AS/400 payroll system. Hardware wise, they needed twenty-four production monitors (one monitor for each machine) and one CAN-to-serial bridge for the central server. It was my job to design the hardware, program the firmware, and then write the code to aggregate the data before inclusion into the AS/400.
