THP Entry: Tinusaur AVR Platform Teaches Noobs, Plays Game Of Life

July 29, 2014 by Kristina Panos 17 Comments

[Neven Boyanov] says there’s nothing special about Tinusaur, the bite-sized platform for learning and teaching the joys of programming AVRs. But if you’re dying to gain a deeper understanding of your Arduino or are looking to teach someone else the basics, you may disagree with that assessment.

Tinusaur is easy to assemble and contains only the components necessary for ATTiny13/25/45/85 operation (the kit comes with an ’85). [Neven] saved space and memory by forgoing USB voltage regulator. An optional button cell mount and jumper are included in the kit.

[Neven] is selling boards and kits through the Tinusaur site, or you can get the board from a few 3rd party vendors. His site has some projects and useful guides for assembling and driving your Tinusaur. He recently programmed it to play Conway’s Game of Life on an 8×8 LED matrix. If you’re looking for the zero-entry side of the AVR swimming pool, you can program it from the Arduino IDE. Be warned, though; they aren’t fully compatible.

The project featured in this post is an entry in The Hackaday Prize. Build something awesome and win a trip to space or hundreds of other prizes.

A Better Google Glass For $60 (This One Folds)

July 28, 2014 by Brian Benchoff 14 Comments

glass For [Tony]’s entry for The Hackaday Prize, he’s doing something we’ve all seen before – a head mounted display, connected to a Bluetooth module, displaying information from a smartphone. What we haven’t seen before is a cheap version of this tech, and a version of Google Glass that folds – you know, like every other pair of glasses on the planet – edges this project over from ‘interesting’ to ‘nearly practical’.

For the display, [Tony] is using a 0.96″ OLED connected to an Arduino Nano. This screen is directed into the wearer’s eye with a series of optics that, along with every other part of the frame, was 3D printed on a Solidoodle 2. The frame itself not only folds along the temples, but also along the bridge, making this HMD surprisingly compact when folded up.

Everything displayed on this head mounted display is controlled by either an Android phone or a Bluetooth connection to a desktop. Using relatively simple display means [Tony] is limited to text and extremely simple graphics, but this is more than enough for some very interesting applications; reading SMS messages and checking email is easy, and doesn’t overpower the ‘duino.

4-Minutes To Entry

July 26, 2014 by Mike Szczys 20 Comments

If you think it’s too much work to write about your projects you’re simply wrong, and I’m going to prove it to you.

The first of this set of videos walks though the steps for submitting an official entry… I did it in under 4 minutes. The second clip covers the extra details you need to post to meet the requirements for the first cutoff on August 20th.

This is the bare minimum needed for your project to be reviewed by the judging panel. But here’s the thing: get your basics down early, then refine as you go along. The Hackaday Prize celebrates the journey of developing interested connected devices. From now until November you should be working on the build and adding to infor to your project post as you go.

Did we mention your odds of winning this thing are really good?

Astronaut Or Astronot: Nobody Won (This Week)

July 25, 2014 by Brian Benchoff 55 Comments

Another week, another round of Astronaut or Astronot, the little lottery thing where we try to give away some fairly expensive tools to a random person on hackaday.io if they have voted for The Hackaday Prize. You should vote. Go here and do that.

This week, the random hacker selected was [oscar6ojeda], but he did not vote. This means he doesn’t get a huge bench power supply. Oh well. I’ll send him a t-shirt and a few stickers. That’s fair compensation for doing nothing, right?

We’re doing the same thing next week, so go here and vote. Voting in previous rounds doesn’t count, so you’ll only win the supply if you vote for The Hackaday Prize project with the most outrageous component.

A Better, Cheaper Smartphone Thermal Imager

thermal

For the last few years, the prices of infrared thermal imaging devices have fallen through the floor, down from tens of thousands of dollars a decade ago, to just about a grand for a very high-resolution device. This dramatic drop in price was brought about by new sensors, and at the very low-end, there are quite a few very inexpensive low resolution thermal imaging devices.

The goal now, it seems, is to figure out some way to add these infrared devices to a smartphone or tablet. There have been similar projects and Kickstarters before, but [Marius]’s entry for The Hackaday Prize is undercutting all of them, and doing it in a way that’s far, far too clever.

Previous ‘thermal imagers on a smartphone’ projects include the Mu Thermal Camera, a $300 Kickstarter reward that turned out to be vaporware. The IR-Blue is yet another Kickstarter we’ve seen, and something that’s actually shipping for about $200. [Marius] expects his thermal imager to cost just $99. He’s getting away with this pricing with a little bit of crazy electronics, and actually designing a minimum viable product.

Both the Mu Thermal Camera and the IR-Blue communicate with their smartphone host via Bluetooth. [Marius] felt radio modules were unnecessary and inspired by the HiJack system where low-power sensors are powered and read through a headphone jack, realized he could do better.

Always the innovator, [Marius] realized he could improve upon the HiJack power harvesting solution, and got everything working with a prototype. The actual hardware in the sensor is based on an engineering sample of the Omron D6T-1616L IR array module, a 16×16 array of IR pixels displaying thermal data on a portable device at 4 FPS.

It’s interesting, for sure, and half the price and quadruple the resolution of the IR-Blue. Even if [Marius] doesn’t win The Hackaday Prize, he’s at least got a winning Kickstarter on his hands. Video of the 8×8 pixel prototype below.

Cosmonaut Or Taikonot: Vote For The Most Outrageous Component

July 24, 2014 by Brian Benchoff 6 Comments

We have a new round of Astronaut or Astronot, the little community voting thing we’re doing for The Hackaday Prize. Why should you care? Because tomorrow (Friday, 10:00 AM Eastern) we’re doing a voters lottery. We’re selecting a random person on hackaday.io, and if that person has voted, they win a pretty awesome bench power supply.

Why are we telling you this now? Because voting in previous rounds doesn’t count for this round. If you want to nab a power supply, you need to vote. We previously gave away an awesome scope, and a very cool 3D printer to a random person on hackaday.io. Judging from previous rounds, I’d guess the odds of us giving away the supply this week are pretty good, but I’m not doing those maths right now. I’ll post a video of the drawing tomorrow around 10:30 Eastern.

THP Hacker Bio: Kenji Larsen

I met up with [Kenji Larsen] at HOPE X last weekend, and I’m fairly certain he was the coolest person at a conference full of really cool people. Talking to him for a little bit, you get a sense of what it would be like to speak with [Buckmister Fuller], [Tesla], or any of the other ‘underappreciated, but not by people in the know’ minds scattered about history. I’ll just let his answers to our hacker bio questions demonstrate that.

7033431402348237268 [Kenji]’s project for The Hackaday Prize is the Reactron Overdrive. It’s not just one board he’s building here, but an entire suite of sensors, interfaces, and nodes that form a complete human to machines – note the plural ‘machines’ – interface. When you consider that no one knows what the Internet of Things actually is, and that [Kenji] is working on IoT 3.0, you get a sense that there’s really something here. Also, his project log has a Tron Recognizer in it. That has to count for something, right?
