3D model of johann517. The models were repaired and checked for printability.
Copper grid in front with aluminium plates at the back side to produce an ion thrust
...Plus with the use of high voltage.
The distance between grid - plates can be changed. The hole on the side is to spy into a little bit (prototype) but also the enclosed version is uploaded
My HV power supply (which is based on small 9V battery) does not have the strength to drive it good enough. Only kicking a candle light very slightly was not worth a video. The HV supply needs a discharge suppressor circuit or it ends up with arcing.
Designed and build on a saturday and currently looking for a good HV circuit diagram...
