Here’s one for all you Arrakids. From Michael D’Argenio comes this simple Raspberry Pi replica of the horripilating Gom Jabbar test from Frank Herbert’s classic science fiction novel, Dune.
We *think* they’ve just released a new movie about it? Something small and arthousey, no doubt.
Fear is the mind killer
Using an ultrasonic sensor, Raspberry Pi, and servo motor, Michael’s contraption successfully stabs you with the Gom Jabbar if you remove your hand from the agony box. And, by stab, we mean ‘taps you with a salvaged clock hand’, and by ‘agony box’, we mean…well, we still mean an agony box, but it’s a repurposed Adafruit cardboard one.
“In this project, I created a Python script that uses gpiozero to interface with an HC-SR04 ultrasonic sensor to detect the presence of a hand, and a servo to actuate the Gom Jabbar,” Michael explains in his Instructables project page. “Multiple processes are used: one for playing the audio and the other to constantly check the ultrasonic sensor to see whether the hand has been removed from the box and actuate the servo motor with the pin. If you leave your hand in for the duration of the test, you can remove it safely at the end. If you remove it before, you will be pricked with the Gom Jabbar.”
Start your own religio-political organisation
Like we said, it’s a simple build, but highly effective nonetheless. With the basics of the technology down, you can now go to town recreating your own screen-accurate agony-box prop, add some more leather straps to your Paul Atreides cosplay, terraform your own spice planet…
