Foam-board upholstery pin disc

Postby McGee2021 » Mon Jun 27, 2016 1:42 pm

i was reading through the past two news letters, and an idea popped in my head. I would combine the foam-board lens disc and the upholstery pin disc, to make a foam-board upholstery pin disc! i cobbled it all together within 10 minutes, copying off of a club disc, and managed to get a raster of sorts putting a led bulb running off of 60 hertz here in the U.S. I still need to polish the dull-ish upholstery pins to get a decent image, but it was good enough for a start. I'll hopefully be able to manage to post some pictures tomorrow or in a few days.
John Logie Baird was obviously the man who sowed the seeds but did not reap the harvest.
