1. Printed gears on a 150$ faux CTC faux Prusa i3 .. not ideal. Sketchup plugin: jimhami42_rack_and_pinion.rbz https://forums.sketchup.com/t/involute-gear-and-worm-gear-plugin/39666/4 2. Mind the gap .. as it is not so much obtaining the sustained spark but focus on the initiation, which shd be ideally half or less before then traveling to the mhz distance. 3. Maker rage! V1 faced an -incident- of impatience of stupidity for stupidity. 4. Gears [deep breath] suck. V1 (pre-smash) was constructed before the gears had been printed - thus halving gears led to variance failures. V2 geared up first. 5. Knock off Nano was trashed - then fried a NodeMCU and servo by using a 12V usb fed power supply bcz wtf?! Burned a new bootloader to faux Nano -- back at it. 6. In principle .. am I right?! No? (>_ლ)
7. FAIL as 30,000 to 40,000 volts regardless of isolation (3 to 5 mm of PLA?!) disrupted electronics and seized the gyroscope. Lesson here? Less is more .. or shielding .. yeah, probably shielding.
