Progress Report - LED brackets now fabricated
Hi
After languishing a short while, the Flat Field project is now back on, using a white plastic bucket from Bunnings.
Today I made the LED brackets (x6) from 20mm x 10mm Alum Angle. Each bracket will be (blind) riveted (via the small hole on the long face) to the inside wall of the bucket at 60° spacing, then a plastic LED holder will be fitted in the large hole on the short face. The 90° angle of the Alum Angle has been eased out to an angle of 110° to ensure that the light cone from each LED fully illuminates the bottom of the bucket, before the photons continue their hopefully even journey to the white, opaque Perspex sheet to be fitted at the top of the bucket.
After that, I will wire the LEDs in Series with a 120Ω Resistor – oh, just remembered, must go out and buy a 20KΩ - 50KΩ Potentiometer.
Cheers
Dennis
