Portal fan recreates a sentry turret using an Arduino

Steven Gioiosa recently signed up for a “Makecourse” class at the University of South Florida, where he was required to build something that featured both an Arduino and a 3D-printed part. As a fan of Portal, and especially the sentry turrets in the game, it was an easy decision to construct one of these devices […]

Building a pool-playing robot prototype with Arduino

Building robots can be (relatively) easy if you’d like something to wander around your room and avoid obstacles, but for complicated control tasks, like shooting pool, things need more development. Engineer “Bvarv” has been working on just such a robot, which currently exists as a one-sixth scale model. Though it’s not currently capable of playing the […]

A LoRa home environment monitoring gateway

When you’re away from your home, perhaps you’d like to know what is going on there. A camera system is one solution, but is fairly data-intensive and might not be the right method if you’d like to monitor information such as temperature and humidity in several zones. For this, Rod Gatehouse decided to build his own LoRa environment […]

Unlock your garage door with a fingerprint

Using an Arduino Micro for control, French teenager “Joebarteam” came up with a way to biometrically secure his garage. If you need to get into your locked garage, what could be better than using your fingerprint? To this end, Joe’ came up with a system that unlocks his door using a fingerprint scanner, and a bistable […]

Scare your friends with a 3D-printed animatronic eyeball

With October still six months away, you may not be thinking about Halloween decorations just yet. However, this Arduino-based ocular assembly could make for a spooky yet simple prop! There are few things more unnerving than an eyeball or three looking at you from some concealed position—such as under clothing as in the project’s video. If […]

Teenage Maker builds his own Arduino drone

When most people decide they’re going to build a quadcopter, they likely go to their favorite online retailer or hobby shop, and get the correct parts to connect together. 17-year-old Maker Nikodem Bartnik instead decided to customize things further, programming an Arduino to act as his flight controller, and constructing a transmitter (or “pilot” as he refers to it) […]

An Arduino Final Countdown Timer

While playing a game called slither.io, Nathan Ramanathan was asked by his father to turn on a wet grinder for “exactly 45 minutes.” As explained, this device uses stones to grind rice into dough, producing material for delicious-looking Dosa cakes. Deliciousness aside, Ramanathan would rather have the grinder stop automatically than wait around for it, […]

Why buy a soldering station when you can build one instead?

As with many products, if you want the best, you’ll pay top dollar for it. After seeing that the supposed best soldering station on the market sells for $500, YouTuber GreatScott! decided to instead purchase the iron and tip for a total of around $100, then reverse-engineer how the station should work. From there, he […]

Add smartphone control to your rolling backpack

Have you ever hopped off the plane at LAX with a… rolling backpack, and wished it would just push itself? Using an Arduino and motor controllers, “TannerTech” made his own robo-backpack. Carrying backpacks around is so 20th century. Modern travelers, of course, get their robotic minions to drive the bags around for them. Or at […]

Geared clock measures time linearly

Jonathan Odom, a full-time designer at Instructables who goes by the name “JON-A-TRON,” decided to make a clock illustrating time’s linearity.  What he came up with was a beautifully crafted (robotically manufactured at the Pier 9 workshop, that is) clock that uses two rack and pinion assemblies to move a line of numbers for hours on […]
