1MV (1,000,000 Volts!) Spark Photographed Between Two Thumb Tacks
I’d say ‘don’t try this at home’ but that never stopped anyone – Giles Read from first acquiring a high voltage generator, then hooking it up to photograph this spark (with accompanying cracking air) between two thumb tacks. You can read more about the process in the description on Flickr.
I saw a little high voltage generator on eBay that promised a one megavolt output from a single Li-Ion cell – and cost about the same as a McBurger.
I had to have one!
It arrived this morning and its output wires were swiftly soldered to a pair of drawing pins (ideal in this application because they’re effectively a nice pointy end backed by a large heatsink).

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
