Junk Pile Projects – Wobbly Christmas Bauble Pulse Motor #2 Rainy day. It’s cold wet and windy outside so time for an indoor junk pile project. Why did I choose a solar project? I was going to use the components from a solar rocker and convert it to battery power but it worked well enough with the ambient light so I left the solar panel in circuit. I have split this over several episodes just testing some different situations. Hopefully I will get a chance to do a final episode in full sunlight one day.
Main components
Solar rocker/wobbler/mover
Left over Christmas bauble
Scrap plywood left from one of those wooden clip together puzzles
Neodymium magnets
For a change I didn’t use hot glue although that would have been fine
Instead I used Poundland superglue fixed with bicarbonate of soda to make it into a thicker consistency and set it quickly.
Sticky tape
Sewing needle
