Roverling 1
Roverling 1 was designed and made over a few weeks from mainly the left overs of an old 3D printer I striped down. These were the bits, plus some printed parts.

Glow Cuboid
Build your own, easy, see how here: https://www.instructables.com/Glow-Cuboid/
Sixty-four LED’s displaying changing patterns and sequences which will never repeat. It measures 100 x 100 mm and has a frosted acrylic front. Runs off USB power.
The patterns are quite addictive and it took weeks to come up with them. There are four types which are selected by turning the cube onto a particular side. Every side produces a different style of pattern.
If you don’t want to build one, you can still enjoy the patterns on You Tube. The videos below are 4k UHD and will be most appreciated on the big screen.

Duck Off
In an attempt to keep the ducks off our jetty and in particular the voluminous amounts of poo, I created the Duck-Off.
How does it work? It detects ducks using passive infrared and mm microwave. It then makes an increasingly louder and scary (for ducks I hope) sound through the horn speaker. There’s also an array of 64 LEDs which strobe at different rates and colour that I hope also scares them off.

Light House night light
This one off was made from a found 3 inch brass foot valve. The ‘globe’ is a 3D print in light weight foaming PLA, in which is mounted 3 LED’s. The ‘glow’ is forever changing.
Control is achieved using an RP2040 programmed in Python. It also contains LiPo batteries and will provide white illumination automatically in case of power failure. It is switched on and off by touch alone. The random algorithm developed has formed the basis of other LED projects.
