In case you’re a fan of the Alien franchise, you need to take a look at this movement tracker mission created by Billy O’Sullivan from the maker channel Shed Tech. Utilizing a Raspberry Pi, it’s themed to seem like expertise straight out of the Alien universe and makes use of sensors to detect movement—making this a working movement monitoring system (opens in new tab).
The movement tracker has two modes that you could allow forwards and backwards on the push of a button. The primary mode features as a demo that simulates movement detection whereas displaying animations on the LCD display screen. The second mode accepts enter from the movement sensors and exhibits the approximated location on the display screen. The system additionally options sound output created by a 3V buzzer that you could toggle on and off.
It’s one among a number of initiatives O’Sullivan had shared earlier than, together with one we had the chance to cowl only a few months in the past. Considered one of his most up-to-date Pi-powered initiatives contains the Armatron, a wearable gadget constructed round our favourite SBC.
His creations contain 3D printing customized shells, and this mission is not any totally different. The case for this movement detector is, in our opinion, a stupendous design and may be 3D printed (opens in new tab) with loads of room to mount the mandatory {hardware} inside. It operates utilizing any 40-pin Raspberry Pi mannequin and requires three HC-SR04 ultrasonic sensors, a buzzer module, a few buttons, and a 100Hz sq. LCD display screen. The unit recharges utilizing a USB charger.
The software program for this mission was additionally created by O’Sullivan utilizing the favored programming language of selection, Python 3, together with the Pygame library. The code is open supply and obtainable over at GitHub (opens in new tab) for anybody who needs to obtain and test it out.
If you wish to recreate this Raspberry Pi mission, take a look at the unique video on YouTube (opens in new tab) to see it in motion, and take a look at the outline for extra construct particulars. If this mission is up your alley, observe Shed Tech for extra cool creations and future microelectronics initiatives.
