Some Hackers Built a Prosthetic Nerf Blaster That Fires by Flexing Your Arms!

 

BRUH! WHERE WAS THIS WHEN I WAS A KID! I had to use my hands like it was a baby’s toy! Anyway, this was done for a pretty good cause, though. A group of hackers at Hackerloop wanted to level the Nerf-fighting playing field for Nicholas Huchet, an individual who didn’t have a full arm, by building him a custom Nerf blaster prosthetic with the ability to automatically fire a projectile by simply contracting his forearm muscles. According to the Medium post, Hackerloop’s Valentin Squirelo chronicled the build in great detail, which included the use of custom 3D-printed parts, Arduino-based electronics, some electromyography sensors that could detect muscle movements, and — of course — a couple of hard-to-find Nerf Swarmfire blasters (hint: the blasters’ round design was VERY optimal for the build).

A LEGO Data Network Protocol?! Are You Foolin’ Me?!

Speed in tech is an awesome thing.  Nowadays many of us can appreciate bullet-quick solid-state hard drives (SSDs) and fiber-optic networks (like Google Fiber; PLEASE come to San Antonio), but the best way to appreciate something is to understand where it all came from. Before the days of the aforementioned technology we now use, there was the telegraph, and even further back we can see that data travel everywhere by train. A hacker named Maximilien recreated that locomotive golden era of transferring information using LEGO, Arduino and Linux.  Even though this method will definitely lack the bandwidth, the point is the nod to the historical relevance of networking.  While the latency of the network is awful, the bandwidth is actually pretty good.

Charge you Cell Phone with FIRE (or candles) & SCIENCE!

For the second time in the last month, the transformer on my street went haywire and the power went out on our street for a few hours.  Fortunately, we had plenty of flashlights and candles (old school FTW) to keep the house well-lit enough; unfortunatley, my phone’s battery is about to die, and there was no available power. DIY weblog Tinkernut shows us how to power your phone with the heat of one of those candles, thanks to thermodynamics, thermoelectric effects, and a Peltier effect device.
