Frugal

My Grandparents came from very modest means. Both were frugal and careful with spending. For example, my Grandmother's kitchen knives had a nearly limitless lifespan as they could be sharpened by hand many, many times without need to buy a new one!

Printer Modification

This is a control board added to a small HP printer that controls the x and y axis motors plus a solenoid that lifts and drops a pen. The control board is attached to a joy stick for etch-a-sketch like drawing on paper in the printer.

Tube B+ Power Supply

Assembled today from parts scavenged from an old PA system, an audio multiplex switch box, and a zip drive box; output of 325 VDC for tube projects.

Magnetic Field

If you did not believe in the effect of a magnetic field on moving electrons....The 70's have returned....a magnet from a tweeter out of Ohm-H speakers

40 Years Ago...

I built this when I was a kid. The tube is a 6U5 with 1M resistors mounted in the rear. We assembled a power supply from parts harvested out of a very old PA system including a 6V4 full wave rectifier tube, transformer, and 16uf cap to provide B+. Remarkably, some many years later, the Magic Eye still works fine. The case partially open to permit access to wires and internal connections.
