I have a memory of my days at TVC back in the late 1960s when someone (I’m sure it was Squire Hill) brought in a beautiful sealed wooden cube he had made, about 3 or 4 inches each side with 5 or 6 lights on one face. It must have been pre LED days. The lights flashed completely at random. We strapped it on the Mole monitor to entertain us as we worked…<\/p>\n

I loved the things that John Howell made out of Perspex  while I was still at the Beeb, and that’s 34 years ago! Best one I remember was one that had spirals of lights flashing in sequence, that served no purpose at all. Now that<\/b><\/i> I call brilliant.<\/p>\n

That was made using 12Volt 100mA ‘pea’ bulbs, 130 of them. Audio split into four frequency bands plus extreme low and extreme high essentially 6 ‘wah-wah’ pedal circuits driving 6 power amps.  It appeared on TOTP behind Julie Felix (TC8 29th April 1970).<\/p>\n

The whole Perspex thing started when I found a piece of clear tube after a \u201cDr Who\u201d derig. I thought ‘I could put a radio in that’ and the light powered radio was born and still going strong, picture below.<\/p>\n
