Add the magnets and iron wire
Instructions from Propel-E 450 | A very powerful windturbine
Put a magnet in every of the 24 gaps. Reverse the magnet (polarity) everytime so we get alternating N-S-N-S... poles. After that, wind the iron wire on the generator until the void is filled:

Put the modified nozzle back onto the printer's hot end
Instructions from Easy CNC Heat Sealer
This is the easiest step - just do step 2 in reverse. Screw your modified nozzle in tightly and don't forget to use a second wrench to isolate your precious linear rods from all that torque. At this point, the hardest part of the mechanical modification...

Mosfet
Instructions from $10 Robot!
The Mosfet adds reverse polarity protection. Insert it with the tab next to the Screw Terminal. You can bend the legs slightly, so that it doesn't fall out when you flip it over.

Display Module - PCB Removal from Bezel
Instructions from SDO Milliohm Meter v1
The display module requires the following modifications to improve performance in this project: Remove the protective film left on the LED display on the PCB.Bypass the reverse power protection and on-board LDO.Cut the grounding link for the negative...

The control circuit
Instructions from Projector Screen
The relay coil is driven by 'remote power' output on the projector. There are no other connections made to the coil. As such, this also performs the needed isolation so if you screw up anything else, you at least don't fry your projector. The projector...
