If you have a 3D printer handy and are looking for a new project to keep you busy over the weekend and beyond you may be interested in this new 3D printable working hand crank power generator.
The portable generator has been created by Thingyverse user EvenErichsen and has been aptly named the Beest and is capable of generating roughly 30 W of power.
As you can imagine the 3D printed parts on the portable power generator take some time to create and its designer estimates but it should take over 200 hours of printing to create all the components.
On the hardware side you need 96 neodymium magnets (25mm diameter x 10mm), about 1,3kg of enameled copper wire, preferably six steel plates, a pile of nuts & bolts, electronics – including an Arduino nano, display, bridge rectifier(s), diodes, capacitors, resistors, voltage regulators etc.
If you want to etch the PCB yourself, you will need a blank 160mm x 100mm copper board and your preferred chemicals. Until I release a set of instructions, consider this a piece of art 😉
