This Raspberry Pi Pico Light Is a Bright Idea

Taking product photos, as anyone who has had to review small shiny black things for the web will tell you, can be extremely difficult to get right. Not only does camera autofocus tend to slide off beautifully designed seamless surfaces, but getting the background and lighting right is extremely difficult too. That’s where this great project, powered by a Raspberry Pi Pico, from four makers on Hackster.io comes in.

It’s a light, but not just any old light. It’s a small studio light that can adjust both its color and intensity via the Raspberry Pi Pico and some Python code. Two custom PCBs sit behind an acrylic panel. One of the boards is a 4×4 Neopixel Matrix with a Raspberry Pi Pico on the back, and a rotary encoder and button which controls the color and brightness. The other board handles power: a LiPo battery shield which includes a charging circuit and a power switch. This part isn’t strictly necessary, as the light can be powered directly over USB.
