With a mouth-operated joystick and “sip and puff” controls, the LipSync aims to make smartphones more accessible for everyone.
For the huge number of people that use them, smartphones have certainly made their lives easier. Unfortunately, these amazing gadgets are difficult to use for those with limited or nonexistent use of their arms and hands. The LipSync attempts to address this issue with a device that can be made in just over a weekend’s worth of work. It uses an Arduino Micro along with a Bluetooth module for communication, and allows someone to interface with the phone using its tiny joystick, as well as the user’s controlled breath.
Smartphones and other similar mobile devices have become a staple piece of technology in this day and age. For people in wheelchairs whom experience difficulties with gross or fine upper body motor control, the usage of mobile devices can be very challenging. The LipSync is an assistive technology device which is being developed to allow quadriplegics the ability to use touchscreen mobile devices by manipulation a mouth-operated joystick with integrated sip and puff controls.
You can find more information on this project, including the files needed to build one, on its Hackaday.io page.
The setup is fairly simple. A PIR sensor detects movement, which automatically triggers a hidden strip of RGB LEDs to illuminate a path as you get out of bed. An RTC module keeps the time and ensures that the lights only turn on between 9pm and 8am. (The good news is that the strip will only stay lit for approximately two minutes, and won’t keep you up for the rest of the night.) A small capacitive touch sensor on the bottom of its case can also be used to test the lighting display outside of operational hours.

Walking the streets of a highly-populated city, or even a crowded event for that matter, comes with certain risks like pickpocketing. Mindful of this, Maker TVMiller has come up with a clever system to prevent bag thieves from unknowingly creeping up behind you. Called the “Arduino MetroPhones,” the device consists of a Nano, an ultrasonic sensor, a digital potentiometer, a coin-cell battery, and a few other components, all housed inside a 3D-printed case.
The metropolitan in its natural habitat; unaware, oblivious, purposefully deafened and subsequent prey. To increase perception thus safety, we wed an Arduino Nano and ultrasonic sensor to regulate volume to proximity to someone behind you; easily deactivated per environment and rechargeable. Beyond this proof of concept, intention for apparel or accessory (purse, back pack) embedding is ideal.
This prototype of a prototype is a mono-version. A stereo version would merely require dual channels. Thus, imagine, you plug your head phones in to your purse strap which is embedded with a MetroPhone with Bluetooth that streams to your smartphone..
Farmbot is the first open source cnc farming machine with the aim to create an open and accessible technology aiding everyone to grow food and to grow food for everyone. It runs on open source hardware like Arduino Mega 2560 and involves a community of contributors on the wiki and forum where you can find documentation, schematics, assembly guides, troubleshooting tips and many more on all currently supported and old FarmBots.
Documentation has been a key element of the project since the beginning and Farmbot founder, Rory Aronson at the 2015 Hackaday SuperConference, gave a talk about why great documentation is the key to building a community of hackers who continue to build upon open source technologies:
Okay, we'll admit that it looks a bit like a baby monitor. But in contrast to those over-engineered pieces of parenting paraphernalia, this DIY cellphone can actually make calls and send texts over GPRS. More importantly, Hackaday claims it was put together by a lone hacker ("Victorzie") from an assortment of off-the-shelf and modded parts, including a TFT touchscreen, lithium ion battery, charging circuit, GPRS module and shield. These components were hooked up to an Arduino Uno microcontroller running a barebones UI and then jammed into a 3D printed case, which makes the device look far more pocketable than some previous hackaphone efforts. The end result inspires big respect for the creator, but also, more grudgingly, for the pro engineers at places like Nokia, who can pull all this stuff together and even get it FCC-approved for just a few dollars.
It looks like Jack Eisenmann has done it again. A couple of years after the hobbyist hacker built his first 8-bit computer, he's cobbled together yet another one, but this time with a whopping 16 cores. Appropriately dubbed the DUO Mega, the multicore wonder is made with 16 ATMega328p microcontrollers, each connected to an 8-bit data bus and designed to interpret a custom bytecode that runs the software. Compiled inside a nondescript plastic bin, the machine is also comprised of 16MHz crystal oscillators attached to each of the aforementioned cores, three Arduino UNO boards, 32kb of SRAM, 512kb of flash memory, eight breadboards, an Ethernet shield, a VGA out port and a multitude of components that combine to look like that mess of wires seen above. Because of all that processing power, this relatively primitive machine multitasks beautifully and can perform complicated calculations at an impressive clip. To get a demo of what this marvelous feat of DIY computing can do, have a peek at Eisenmann's video, complete with an 8-bit soundtrack, after the break.
