While sheltering at home, built this simple transistor short wave radio from a schematic here http://www.mtmscientific.com/swradio.html
Cut out and engraved the front panel and the pointer. I do all my vector design work with Affinity Designer. The gears were made using .svg files from this terrific site (https://geargenerator.com) on my Glowforge laser cutter.
And it works!

The coat rack is a collaborative project with my wife Pat. She created the beautiful tiles in the Arts & Crafts tradition and I made the wood parts from quarter-sawn white oak.
A lot of the lamps I've seen online have had old steam and pressure gauges attached, which are non-functional (I hope!). I've include a AC voltmeter on this one that works.
Belmar had a terrific movie theatre on Main Street when I grew up called the Rivoli. My "Little Library" is my way of remembering all the good times had there.
I'm fascinated by the "steam punk" lamps I've seen online so decided to try my hand at a few.
Got a Glowforge laser cutter/engraver so thought I would try a 3D panel of Belmar, NJ.
Saw a kit for a wooden mechanical toy while in a shop in England. "Rocky" is that toy blown up a few times. He's powered by a 12 volt DC motor and has an "electric eye" that senses when a shadow passes in front. His tail rotates and his lower jaw moves for about 10 seconds when triggered. Fun project!

Projector Lift
A photograph sometimes allows a painter to capture the action of a subject, such as a dancer, and then take all the time needed to put the subject on canvas. Printed photos do not always allow the artist to see small details, however, projecting the image makes those details easier to see. The projector often needs to raised and lowered when working with various size images and in order to minimize "keystone."

This is my "high tech solution to a low tech problem."




The lift uses heavy-duty drawer slides as guides and a linear actuator with 20" travel. The linear actuator came with a corded remote control.
