Hackaday Prize Entry: Head-up For High Voltage

October 5, 2016 by 43 Comments

[Alain Mauer] wanted to build something like a Google Glass setup using a small OLED screen. A 0.96 inch display was too large, but a 0.66 inch one worked well. Combining an Arduino, a Bluetooth module, and battery, and some optics, he built glasses that will show the readout from a multimeter.

You’d think it was simple to pull this off, but it isn’t for a few reasons as [Alain] discovered. The device cost about 70 Euro and you can see a video of the result, below.

Hackaday Prize Entry: Making A Book Reader That Can Survive Kindergarten

October 4, 2016 by 5 Comments

[atomicthomas] is a dedicated teacher. One only has to look at the work he’s been putting into book readers for for the past sixteen years. With hardware like the Pi Zero threatening cheap computers just over the supply chain horizon, he’s begun to set his sights higher.

It all started with headphones and audio tapes. For all of us who got to use tapes and school headphones, we know the flaws with this plan. Nothing lasted the sticky and violent hands of children for long. When video recordings of book became available, DVD players suffered similar fates.

So, he began to rip his tapes and DVDs to his computer. However, the mouse has a warning about small parts on it for a reason, and didn’t last long either. So, he built a computer with arcade buttons and a Raspberry Pi. This one ran a heavily simplified version of a media manager and worked well. Even the special needs children had no problem navigating. A second exploration with an iMac and a Nintendo controller worked even better. Apparently all five year olds instinctively understand how to use a Nintendo controller.

Using the user test data, in his most recent iteration he’s working on a sub-twenty-dollar reading computer in a Nintendo controller. It’s not the most technically in depth hack we’ve ever covered, but it certainly ranks up there for harsh environments.

Hackaday Prize Entry: FPGAs For The Raspberry Pi Zero

October 2, 2016 by 14 Comments

The Raspberry Pi is the Arduino of 2016, and that means shields, hats, add-ons, and other fun toys that can be plugged right into the GPIO pins of a Pi. For this year’s Hackaday Prize, [Valentin] is combining the Pi with the next age of homebrew computation. He’s developed the Flea Ohm, an FPGA backpack or hat for the Pi Zero.

The Flea Ohm is based on Lattice’s ECP5 FPGA featuring 24k LUTs and 112kB BRAM. That’s enough for some relatively interesting applications, but the real fun comes from the added 32MB or 128MB of SDRAM, a micro SD card slot, USB + PS/2 host port and an LVDS output.

The combination of Raspberry Pis and FPGAs are extremely interesting and seem to be one of the best FPGA learning platforms anyone can imagine. Another Hackaday Prize entry, the ZinqBerry does a similar trick, but instead of a Pi hat, the ZinqBerry drops a Xilinx Zynq with an FPGA and ARM Cortex A9 core onto a board with Ethernet, HDMI, and USB.

If it’s a Flea or a Zinq, the age of FPGA’d Raspberry Pis is quickly approaching, and hopefully we’ll see them as finalists in the Hackaday Prize. You can check out a video of the Flea Ohm below.

Hackaday Prize Entry: The GECK

October 1, 2016 by 10 Comments

The Garden of Eden Creation Kit, or GECK, is the MacGuffan of Fallout 3 and the name of the modding tool for the same game. In the game, the GECK is a terraforming tool designed to turn the wasteland of Washington DC into its more natural form — an inhospitable swamp teeming with mosquitos.

A device to automatically terraform any environment is improbable now as it was in Wrath of Khan, but a “Garden of Eden Kit” is still a really great name. For their Hackaday Prize entry, [atheros] is building a simplified version of this terraforming device. Instead of turning the Tidal Basin into potable water or turning a nebula into a verdant planet, [atheros]’s Garden of Eden Watering Kit turns empty potted plants into a lush harvest of herbs.

The device, like most home gardening solutions presented in this year’s Hackaday Prize, isn’t geared towards irrigating acres of crops. This is just a simple, small device meant to water a few herbs growing in a pot on a balcony. The hardware consists of a Teensy LC and a small OLED for command and control. A soil moisture sensor goes into each pot, and a few 12V peristaltic pumps water the plants from a bucket reservoir.

For the home gardener, it’s the perfect setup to grow some herbs, some chilis, or a cherry tomato plant that produces a year’s worth of tomatoes every week.  It’s a great adaptation of off the shelf tech, and a great entry for the Hackaday Prize.

Hackaday Prize Entry: Crowdsourced Tactile Interfaces

September 30, 2016 by 5 Comments

Your microwave, your TV, and almost the entire inventory of Best Buy have one thing in common: they all uses membrane switches for user interaction, and that means these devices are inaccessible for the blind. This project for the Hackaday Prize is going to change that by building a crowdsourced effort to design Braille keypads for thousands of appliances.

There are two aspects of this project that are exceptionally interesting, the least of which is how to make Braille keypads for a microwave. This is done with a 3D printer using a flexible or semi-flexible filament. These keypads are designed to overlay the membrane keypad on consumer electronic devices, and the initial testing reveals these keypads are robust and useful enough for blind users.

A 3D printed overlay for a microwave is simple, though. The big question is how these overlays are designed. For this, the project suggests a crowdsourced effort of hundreds of designers turning photographs of keypads into Braille overlays. The process begins with a few pictures of a keypad with a reference object – for example, a dollar bill. These photographs are scaled to the correct dimensions, a few outlines are made, and the buttons with Braille text are designed. It’s a brilliant use of people who have just enough experience in Photoshop to be useful, and since this is a crowdsourced effort, work isn’t duplicated. The keypad overlays for one specific make and model of microwave can be printed over and over again, bootstrapping an effort to make membrane keypads useful for all blind people.

Calling All Procrastinators

September 30, 2016 by 13 Comments

We have your number… you’re one who likes to while away the daylight hours, then make a mad effort throughout the night to finish everything before the sun again rises. In fact, that describes a lot of us Hackaday writers.

Put those well-honed cramming skills to good use this weekend, because Monday morning is the deadline to enter the 2016 Hackaday Prize. The current challenge is to show us your Assistive Technology. Prototyping some hardware to make life a little bit better for people dealing with a disability, to help those who are aging in place, to provide more widespread access to health care, and the like. We will pick 20 entries from this challenge to win $1000 each and become eligible for one of the five huge prizes.

Huge prizes you say? We’re talking about a grand prize of $150,000 and a residency at the Supplyframe Design Lab in Pasadena, plus four other cash prizes of $25k, $10k, $10k, and $5k. Twenty final projects have been chosen from each of the first four challenges, and there have already been over 1000 total entries! But your chances of pulling a rabbit out of the hat this weekend are still really good. So far there are just under 200 entries in this final challenge — twenty will move forward on Monday.

Call up your friends and stock up on Red Vines and Red Bull (Club Mate if you can get it). Occupy your hackerspace and get to work. If you are pulling all nighter’s in a bid to take Assistive Technology by storm, make sure you let us know on Twitter so we can follow along.

Hackaday Prize Entry: Explore M3 ARM Cortex M3 Development Board

September 29, 2016 by 19 Comments

Even a cursory glance through a site such as this one will show you how many microcontroller boards there are on the market these days. It seems that every possible market segment has been covered, and then some, so why on earth would anyone want to bring another product into this crowded environment?

This is a question you might wish to ask of the team behind Explore M3, a new ARM Cortex M3 development board. It’s based around an LPC1768 ARM Cortex M3 with 64k of RAM and 512k of Flash running at 100MHz, and with the usual huge array of GPIOs and built-in peripherals.

The board’s designers originally aimed for it to be able to be used either as a bare-metal ARM or with the Arduino and Mbed tools. In the event the response to their enquiries with Mbed led them to abandon that support. They point to their comprehensive set of tutorials as what sets their board apart from its competition, and in turn they deny trying to produce merely another Arduino or Mbed. Their chosen physical format is a compact dual-in-line board for easy breadboarding, not unlike the Arduino Micro or the Teensy.

If you read the logs for the project, you’ll find a couple of videos explaining the project and taking you through a tutorial. They are however a little long to embed in a Hackaday piece, so we’ll leave you to head on over if you are interested.

We’ve covered a lot of microcontroller dev boards here in our time. If you want to see how far we’ve come over the years, take a look at our round up, and its second part, from back in 2011.
