Don’t Tase Me, Keeb!

Don’t Tase Me, Keeb!

Okay, so this doesn’t really use a taser — that’s just click bait and we apologize. An actual taser would be a terrible way to train yourself to be a better typist, because depending on where you choose to deliver the shock, you could damage your typing nerves pretty quickly with a few milliamps at 50,000 volts.


Instead of a taser, [nobody6502] got a pack of prank gum off of Amazon that delivers a much more doable shock that is painful enough to get the user to type more carefully. [nobody6502] set up a simple no-pain, no-train website that presents random English words one at a time and checks for typos against an open-source list of nearly half a million entries. Misspell a word, and a get a relay-driven shock from the gum circuit.


The main brain of this pain trainer is a Particle Argon board which has I/O pins that can be controlled from the web. When the website detects a typo, it sends a signal to the Argon, which turns on a relay that activates the shock mechanism. What’s most impressive is that [nobody6502] doesn’t have a full-blown computer and programmed everything on an iPad. Check out the build video after the break.


Are you a hunt and peck typist? There’s a negative reinforcement keyboard for that.
