David Bellerose, a retired electronic equipment repairman for the New York State Thruway, has had a variety of careers that have honed the DIY skills he employs in his Lady Lake, FL, workspace.
Bellerose has been a US Navy aviation electronics technician and a computer repairman. “I also ran my own computer/electronic and steel/metal welding fabrication businesses, so I have many talents under my belt,” he says.
Bellerose’s project interests include model rockets, video security, solar panels, and computer systems. “My present project involves Intersil ICM7216D-based frequency counter modules to companion with various frequency generator modules, which I am also designing for a frequency range of 1 Hz to 12 GHz,” he says.
His workspace is an 8′-by-15′ shed lined with shelves and foldable tables. He describes how he tries to make the best use of the space available:
“My main bench is a 4′-by-6’ table with a 2’-by-6’ table to hold my storage drawers. A center rack holds my prototype units—one bought on eBay and two others I designed and built myself. My Tektronix 200-MHz oscilloscope bought on eBay sits on the main rack on the left, along with a video monitor. On the right is my laptop, a Heathkit oscilloscope from eBay, a 2.4-GHz frequency counter and more storage units. All the units are labeled.
“I try to keep all projects on paper and computer with plenty of storage space. My network-attached storage (NAS) totals about 23 terabytes of space.
“I get almost all of my test equipment from eBay along with parts that I can’t get from my distributors, such as the ICM7216D chips, which are obsolete. I try to cover the full EMF spectrum with my test equipment, so I have photometers, EMF testers, lasers, etc.”
