3D model of johann517. The models were repaired and checked for printability.
Electrostatic generator - single disc version
Simplified ES generator with added
...さらに表示 capacitors and flash
light (measured breakdown ~ 6.5 kV). Common 9V battery to power motor and turn the disc. The disc can also be turned by hand and the charge builds up very quickly.
Designed and built within two days (weekend) and to be seen
as a draft version, this little machine produces a lot of current @ high voltage - always be careful!
More info will follow...
Additional Information - first part:
The blue wires are contacting the disc. Either thin lize wire or carbon fibre (better), the green wires end in close proximity to the disc and do not touch.
Connection:
blue/top/left - connected to aluminium plate directly behind
blue/bottom/left - connects to blue/top/right
blue/bottom/right - connected to aluminium plate directly behind
green wires are output - connected with capacitor legs, parallel is the flash light or spark gap (discharges bad for your ears)
backside plate added
What learned - slower is better. Hyperspeed as shown in the video is nonsense. A lot of loses through fine blue mesh all over the segments (seen in the dark). Next machine might be smaller - or not depends if this discharges can be reduced somehow.
