A DIY Segway-style vehicle

Thursday, December 8th, 2016

Instructables user “stoppi71” has been building a DIY Segway for a while now, and just posted a bunch of info on the project.

Balancing on two side-by-side wheels is rather difficult, though as the original Segway showed us, it’s quite possible with electronics to help. Naturally, hobbyists have tried to duplicate this effort, including stoppi71, who started his experiments several years ago. He uses both an accelerometer and gyroscope to determine the angle, along with PID control to apply the correct amount of power to each wheel. Buttons on either side handle steering. (more…)

Peeqo is a desktop bot that communicates through GIFs

Thursday, December 8th, 2016

If you’ve been looking for a robotic assistant with the functionality of an Amazon Echo and the cuteness of a Disney character, you’re in luck. That’s because Abhishek Singh has created Peeqo, an open-source DIY device that responds to human speech through GIFs.

Peeqo has a Raspberry Pi 3 for his brain along with a pair of Arduino Mini boards for controlling movement and LED notifications. The 3D-printed bot is equipped with a half-dozen servos, four custom microphones, a NeoPixel ring on top of his head, a camera at his chest, a USB speaker, and an LCD display. (more…)

An Arduino round word clock

Tuesday, December 6th, 2016

After considering building a square word clock, Maker Roald Hendriks and his sister came up with something a bit more unique!

Clocks, being decorative, useful and easily hackable, have been targets for creative types, likely from when they were first invented. You’d think maybe all ideas for new clocks have been exhausted. Fortunately, human ingenuity never seems to run dry, and this latest device tells time using Arduino Uno-controlled LEDs.

Outer numbers on the modified IKEA PUGG wall clock illuminate to indicate the hour, while words on the inside represent the minutes. These minutes are literally spelled out in Dutch phrases reveal the particular time, but if you don’t speak the language, the position of the LEDs should give you some clue as to what is going on.

The Sandwich-o-Matic will make your lunch automatically

Tuesday, December 6th, 2016

Love eating lunch, but hate making it? Good news, an automated machine may soon be able to take care of the task for you. Meet Sandwich-o-Matic, a voice-controlled, robotic sandwich-building station.

The project–which was created during a thirty-six hour hackathon by the team of Clive Chan, Colin Daly, Alex Foley and Wilson Wu–is based on an Arduino and a Photon. A rotating dispenser is driven by a series of servos, while a DC motor is responsible for a toaster-lifting mechanism. The backend is running Node.js, hosted on AWS, and the Google Cloud Platform handles the voice-to-text features.

The Sandwich-o-Matic accepts both voice and NFC requests. Simply place your order by saying the ingredients, or tapping their respective images on an accompanying menu. The device will then begin crafting your lunch from scratch. (more…)

An Arduino-controlled automated whiskey distillery

Monday, December 5th, 2016

If you simply want to have a drink now and then, building your own automated distillery probably isn’t the easiest way to obtain alcohol. As shown in this Instructables post, however, it can be done. On the other hand, if you create your own “NanoStillery,” you’ll have to contend with possible legal and safety issues while running the process… and of course, the risks of actually using the product.

Though the writeup appears quite good, with three control panels, custom mechanical components and a nicely-welded frame, it’s likely not a good project to attempt without a bit of engineering experience!


The Rex800 looks like a dinosaur Terminator

Monday, December 5th, 2016

The Rex800 looks like a dinosaur Terminator, a terrifying proposition, and perhaps a great merchandising opportunity!

YouTuber “RobitFactory” is in the process of creating a 1/10 replica of the “Sue” dinosaur skeleton, now featured at the Field Museum of Natural History in Chicago. What he has at the moment is a rough frame made out of tubing, as well as a metallic gray head with glowing red eyes.

The video takes us through the build process, along with some of RobitFactory’s future plans which include voice-activation. It’s an ambitious project, and in preparation for upgrades, he’s switched out the Arduino Uno used originally for a Mega board, and installed a Molex connector on the head so it can be easily disconnected. It will be exciting to see where this build goes!


Wrist thrusters let you fly through the water effortlessly

Friday, December 2nd, 2016

These small arm-mounted propeller units can carry a skin diver through the water with minimal effort.

YouTuber “PeterSripol” had only a week to prepare for his trip to Hawaii. Rather than purchase a set of fins or a snorkel, he instead hooked up two T100 thrusters that he had lying around to wrist straps. In his setup, these thrusters are controlled by a button interfaced with an Arduino that allows the user to select one of three power levels. (more…)

Adding an “extra sense” with rangefinders

Thursday, December 1st, 2016

Using ultrasonic sensors attached to a person’s arm, researchers have found a way to let you “feel” distant objects.

The concept of this project is surprisingly simple, but as shown in the test video below, seems to work quite well. Using an Arduino Uno to coordinate everything, when rangefinders see a nearby object, like a wall, the system triggers the corresponding vibrators. This allows someone to sense what is nearby without seeing or touching it.

An obvious use case for something like this would be to help visually-impaired people navigate. Perhaps it could also serve in an application where you need to pay attention to something you can’t quite see, sort of like how an animal’s whiskers warn them of danger before contact is made. (more…)

This wireless game controller looks like a rug

Thursday, December 1st, 2016

Cut in the shape of a gamepad, this controller sits on the floor for kids to enjoy!

Maker Jegatheesan Soundarapandian had gotten bored with computer games, and decided he, or rather his daughter, needed a new way to interact with the PC. What he came up with was a controller covered in cloth, with switches embedded between this covering and a wooden base.

Switches were made out of CDs and aluminum foil, which could be a good technique for others experimenting with unique interface devices. Control is accomplished with an Arduino Uno that communicates with a PC via a Bluetooth module. (more…)
