A small TeslaCoil fully made of acrylic plastic. The cool thing about this is that every part is transparent. This coil is driven by the power supply of my large DC Teslacoil. Total height 44cm, max output voltage - 380.000 Volts (57cm arc length).
The rotary gap is placed underneath the base of the teslacoil, this makes it shine nicely into the dark.
As you might notice, there is no earth strikering above the primary coil. I did not make it because i thought it simply wasnt nessecary, lets jus say the results outperformed my wildest expectations.
A nice tool on the internet for calculating self capacitance of helical coils: http://deepfriedneon.com/tesla_frame6.html
