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.
Thanks to [Heladera Dragon] and [Alvarito050506] for tipping us off.

Somehow I’m thinking of an early Simpson’s episode where everyone in the family is delivering electrical shocks to each other.
Yes! In family therapy.
99.9999% of people mispronounce “agnostic” and 99.99% of people say “taser” when they mean stun gun.
Normally I’d find such a comment as this just shocking, but to be completely honest, I just don’t care one way or the other.
Wait, what? What’s the wrong way? Adj-nostic? Ag-know-stic?
Ag-naw-stick is how I’ve always done
It’s the prefix ‘a-‘ meaning not or without followed by ‘gnostic’ from the Greek ‘gnosis’ meaning knowledge. So the pronunciation should be like ay – gno – stic
Hey, you’re a month early for April Fool’s Day. I couldn’t believe I’ve been pronouncing “agnostic” wrong all my life, so I checked four different dictionaries. They all agree with me that the “a” in the first syllable is pronounced as in “aggie”, not as in “A-bomb”. IPA / ægˈnɒs tɪk /
While I was there I discovered there’s no dictionary entry for “gullible”!
Really?!?
Of course not! It’s a proper name, as in “Gullible’s Travels”.
If I remember correctly, there are some online typing courses which signal errors with a sound effect. It should be easy to use it to drive the punishing circuit. There are supposedly even sites which describe circuits that convert sound into some kind of electric stimulation…
Great idea! I ended up doing what I did mostly because of the lack of a computer to program with. I’m sure with a computer I would have just used a regular typing test and communicated with the arduino over serial
