Hackaday Prize Entry: Simpsons Hands

The creators of this Hackaday Prize entry say every month a new 3D-printed prosthetic solution comes on the scene. That doesn’t mean they’re not doing something different with their entry; yes, they’re still building a prosthetic hand, but they’re putting their own spin on it. This one isn’t using a string/cable/tendon setup, and the hand doesn’t even have four fingers. [Giovanni] and [Jenny] are going their own way, and what they’ve come up with is pretty special.

The most obvious feature of this prosthetic hand is a missing digit – Simpsons Hands – but this makes a lot of sense if you think about it. It’s doubtful any 3D-printed prosthetic hand will play a piano or touch type in the near future, so a pinkie finger is an appendix; an unneeded vanity that just increases the BOM and makes things harder to fit together.

Apart from the Simpsons Hands, this prosthetic hand is more or less what you would expect. The circuitry is just an Adafruit ATmega board, the mechanism is just a few servos, and the mechanics are well designed in carbon fiber PLA. What makes this prosthetic hand special for the team is that it’s the first of its kind in their native Colombia. Even if there’s a new 3D-printed prosthetic hand on Thingiverse every few weeks, this project makes it a truly global effort, and a great entry for the Hackaday Prize.

One thought on “Hackaday Prize Entry: Simpsons Hands

  1. I know there is this pervasive “Simpsons did it first” thing but cartoons have had missing digits since forever. It’s just easier on the animators and in games it’s just easier on the poly count.

    That said I can appreciate breaking away from the “make it normal” mold to the ends of “make it functional”. Personally if I needed a prosthetic I think I’d opt for function over form.
