Brief

Make a light ring that would mount on a Nikon D80 equipped with a lens capable of wearing a HB-32 hood.

Concept

36 white LEDs mounted on a ring of acrylic that would wedge onto the HB-32 hood (which has a mid-point diameter of ~80mm). The power source (4xAA batteries) would mount onto the Nikon D80's hot shoe mount along with controls for brightness and off/on.

Components

• A3 5mm acrylic = £5.40
• 5mm white LED (30,000mcd) (£0.64) x 36 = £23.04
• SPST rocket switch (£0.41) x 1 = £0.41
• AA battery holder (£0.14) x 2 = £0.28
• 10K potentiometer (£0.57) x 1 = £0.57

Total = £29.70
