Hackaday Prize Entry: A Manual, CNC Pick And Place Machine

Posted on by

Everyone who wants a 3D printer probably already has one, and even laser cutters and CNC machines are making their way into garages and basements ’round the world. Pick and place machines are the next great frontier of personal manufacturing, and even though that’s a long way off, [Tegwyn]’s project for this year’s Hackaday Prize is bringing us that much closer to popping down 0201 LEDs reliably.

This project is a manual pick and place machine — otherwise known as ‘tweezers’. It’s a bit more complicated than that, because the entire idea behind [Tegwyn]’s build is to decouple a human’s …read more

Hackaday Prize Entry: Sonic Glasses

Posted on by

This year, the Hackaday Prize is going to find the most innovative and interesting assistive technologies. Whether that’s refreshable Braille displays or reliable utensils for the disabled, the finalists for the Assistive Technologies portion of the Prize will be creating some of the most interesting tech out there.

For his entry into the Assistive Technology part of the Prize, [Pawit] is building binaural glasses for the blind. It’s difficult to navigate unknown environments without a sense of sight, and these SonicScape glasses turn cheap distance sensors into head-mounted sonar.

The glasses are built around a pair of ultrasonic distance sensors …read more

Hackaday Prize Entry: The Weedinator Project, Now with Flame

Posted on by

We like that the Weedinator Project is thinking big for this year’s Hackaday Prize! This ambitious project by [TegwynTwmffat] is building on a previous effort, which was a tractor mounted weeding machine (shown above). It mercilessly shredded any weeds; the way it did this was by tilling everything that existed between orderly rows of growing leeks. The system worked, but it really wasn’t accurate enough. We suspect it had a nasty habit of mercilessly shredding the occasional leek. The new version takes a different approach.

The new Weedinator will be an autonomous robotic rover using a combination of GPS and …read more

Hackaday Prize Entry: Fochica Alerts You

Posted on by

It seems like no one should need to be reminded about the importance of not leaving children in cars, but it still happens. The Fochica project is a Hackaday Prize entry that equips the family minivan with car seat monitors—the name comes from FOrgotten CHild in Car Alert.

It’s an Open Source project consisting of a Bluetooth LE-equipped Arduino that monitors whether the seat is empty or occupied. Paired with a phone app, Fochica monitors pressure sensors and the seat belt’s reed switch to determine whether there’s a kid there. The user’s app checks whether he …read more

Hackaday Prize Entry: CPAP Humidifier Monitor Alarm

Posted on by

CPAP (Continuous Positive Airway Pressure) machines can be life-changing for people with sleep apnea. [Scott Clandinin] benefits from his CPAP machine and devised a way to improve his quality of life even further with a non-destructive modification to monitor his machine’s humidifier.

With a CPAP machine, all air the wearer breathes is air that has gone through the machine. [Scott]’s CPAP machine has a small water reservoir which is heated to humidify the air before it goes to the wearer. However, depending on conditions the water reservoir may run dry during use, leading to the user waking up dried out …read more

Hackaday Prize Entry: Bloodhound Autonomous Radiolocation Drone

Posted on by

If you’re a first responder — say, searching for someone lost in the outback, or underneath an avalanche — and you’re looking for someone with a radio beacon, what’s the fastest way to find that beacon? Getting up high would be a good idea, and if you’re using radio direction finding, you’ll want to be able to cover a lot of ground quickly if only to make the triangulation a bit easier. High and fast — sounds like the perfect opportunity for a drone, right?

[Phil Handley]’s Bloodhound project is an autonomous drone that can scan a wide area, listening …read more

Hackaday Prize Entry: E.R.N.I.E. Teaches Robotics and Programming

Posted on by

[Sebastian Goscik]’s entry in the 2017 Hackaday Prize is a line following robot. Well, not really; the end result is a line following robot, but the actual project is about a simple, cheap robot chassis to be used in schools, clubs, and other educational, STEAM education events. Along with the chassis design comes a lesson plan allowing teachers to have a head start when presenting the kit to their students.

The lesson plan is for a line-following robot, but in design is a second lesson – traffic lights which connect to a main base through a bus and work in …read more

Hackaday Prize Entry: Staircane, a Walker That Takes the Stairs

Posted on by

[Jim]’s aunt has lived in the same house for the last 50 years. She loves it there, and she wants to stay as long as possible. There’s a big problem, though. The house has several staircases, and they are all beginning to disagree with her. Enter Staircane, [Jim]’s elegant solution that adds extendable legs to any standard walker.

Most of the time, walkers serve their purpose quite well. But once you encounter uneven ground or a staircase, they show their limitations. The idea behind Staircane is a simple one: quickly extend the back or front legs of a walker depending …read more

Hackaday Prize Entry: MappyDot, a Micro Smart LiDAR Sensor

Posted on by

[Blecky]’s entry to the Hackaday Prize is MappyDot, a tiny board less than a square inch in size that holds a VL53L0X time-of-flight distance sensor and can measure distances of up to 2 meters.

MappyDot is more than just a breakout board; the ATMega328PB microcontroller on each PCB provides filtering, an easy to use  I2C interface, and automatically handles up to 112 boards connected in a bus. The idea is that one or a few MappyDots can be used by themselves, but managing a large number is just as easy. By dotting a device with multiple MappyDots pointing in different …read more
