Hackaday Prize: 20 Projects That Make Us All Citizen Scientists

July 18, 2016 by Brian Benchoff 8 Comments

We live in a time of unparalleled access to technology and this has the power to make life better for everyone. Today we are excited to announce twenty spectacular builds that use access to technology to move scientific exploration within the reach of all. These are the winners of the Citizen Scientist challenge of the 2016 Hackaday Prize. Themes tackled in this round include blood glucose monitoring, insole sensing for analyzing your footfalls, lab equipment like automated microscopy, sensors to measure the world around us, and more.

The winners for the Citizen Scientist portion of the Hackaday Prize are, in no particular order:

The Hackaday Prize is the greatest hardware competition on earth. We want to see the next great Open Hardware project benefit everyone. We’re working toward that by recognizing people who build, make, and design the coolest and most useful devices around.

These twenty projects just won $1000 and will now move on to the final phase of The Hackaday Prize, to be judged by our fourteen celebrity judges. Awesome! Now get to work: there’s a lot the hackers behind these projects need to do before the final judging in October where they’ll compete for the grand prize of $150,000 and four other top prizes.

If your project didn’t make the cut, there’s still an opportunity for you to build the next great piece of hardware for The Hackaday Prize. The Automation Challenge is currently under way. It encourages everyone to build devices that make your life easier.

Automate your life; build a device that makes your breakfast, a robot to mow your lawn, or software that does your taxes. Build a device that automatically tracks laundry detergent, automates washing the dishes, or a robot that obeys every command.

Like the Design Your Concept, Anything Goes, and Citizen Science rounds of The Hackaday Prize, the top twenty projects will each win $1000, and move on to the Hackaday Prize finals for a chance to win $150,000 and a residency at the Supplyframe DesignLab in Pasadena.

If you don’t have a project up on Hackaday.io, you can start one right now and submit it to The Hackaday Prize. If you’re already working on the next great piece of hardware design, add it to the Automation challenge using the dropdown menu on the sidebar of your project page.

Sonic 3D Printer Auto Bed Leveling Makes A Swoosh

July 18, 2016 by Moritz Walter 49 Comments

3D Printering: the final frontier. These are the voyages of another 3D printer hack. Its mission: to explore strange new ways of leveling a print bed.

So far, we’ve had servo probes, Allen key probes, Z-sled probes, inductive and capacitive contactless switches, just to name a few. All of them allow a 3D printer to probe its print bed, calculate a correction plane or mesh, and compensate for its own inherent, time variant, inaccuracies.

SoftBank Bought ARM

July 18, 2016 by Elliot Williams 44 Comments

$32 billion USD doesn’t buy as much as it used to. Unless you convert it into British Pounds, battered by the UK’s decision to leave the European Union, and make an offer for ARM Holdings. In that case, it will buy you our favorite fabless chip-design company.

The company putting up 32 Really Big Ones is Japan’s SoftBank, a diversified technology conglomerate. SoftBank is most visible as a mobile phone operator in Japan, but their business strategy lately has been latching on to emerging technology and making very good investments. (With the notable exception of purchasing the US’s Sprint Telecom, which they say is turning around.) Recently, they’ve focused on wireless and IoT. And now, they’re going to buy ARM.

We suspect that this won’t mean much for ARM in the long term. SoftBank isn’t a semiconductor firm, they just want a piece of the action. With the Japanese economy relatively stagnant, a strong Yen and a weak Pound, ARM became a bargain. (SoftBank said in a press release that the Brexit didn’t affect their decision, and that they would have bought ARM anyway. Still, you can’t blame them for waiting until after the vote, and the fallout, to make the purchase.) It certainly won’t hurt SoftBank’s robotics, IoT, or AI strategies to have a leading processor design firm in their stable, but we predict business as usual for those of us way downstream in the ARM ecosystem.

Thanks [Jaromir] for the tip!

DIY Motion Control Camera Rig Produces Money Shots On A Budget

July 18, 2016 by Moritz Walter 24 Comments

Motion control photography allows for stunning imagery, although commercial robotic MoCo rigs are hardly affordable. But what is money? Scratch-built from what used to be mechatronic junk and a hacked Canon EF-S lens, [Howard’s] DIY motion control camera rig produces cinematic footage that just blows us away.

[Howard] started this project about a year ago by carrying out some targeted experiments. These would not only assess the suitability of components he gathered together from all directions, but also his own capacity in picking up enough knowledge on mechatronics to make the whole thing work. After making himself accustomed to stepper motors, Teensies and Arduinos, he converted an old moving-head disco light into a pan and tilt mount for the camera. A linear axis was added, and with more degrees of freedom, more sophisticated means of control became necessary.

Russian Decapping Madness

July 18, 2016 by Elliot Williams 37 Comments

It all started off innocently enough. [mretro] was curious about what was inside a sealed metal box, took a hacksaw to it and posted photographs up on the Interwebs. Over one hundred forum pages and several years later, the thread called (at least in Google Translate) “dissecting room” continues to amaze.

If you like die shots, decaps, or teardowns of oddball Russian parts, this is like drinking from a firehose. You can of course translate the website, but it’s more fun to open it up in Russian and have a guess at what everything is before peeking. (Hint: don’t look at the part numbers. NE555 is apparently “NE555” in Russian.)

From a brief survey, a lot of these seem to be radio parts, and a lot of it is retro or obsolete. Forum user [lalka] seems to have opened up one of every possible Russian oscillator circuit. The website loads unfortunately slowly, at least where we are, but bear in mind that it’s got a lot of images. And if your fingers tire of clicking, note that the URL ends with the forum page number. It’d be a snap to web-scrape the whole darn thing overnight.

We love teardowns and chip shots, of old gear and of new. So when you think you’ve got a fake part, or if you need to gain access to stuff under that epoxy blob for whatever reason, no matter how embarrassing, bring along a camera and let us know!

Thanks [cfavreau] for the great tip!

Hackaday Prize Entry: A Better Way Of Cheating

July 17, 2016 by Brian Benchoff 26 Comments

Believe it or not, some video games are still developed for the PC. With video games come cheat codes, and when they’re on the PC, that means using a keyboard. You can easily program any microcontroller to send a string of characters over a USB port with the touch of a button. Believe it or not, a lot of people haven’t put these two facts together. [danjovic] has, leading him to build a simple and cheap USB keystroke generator for quickly typing in cheat codes.

[danjovic] is basing his build around a Digispark, a cheap, USB-enabled ATtiny85 dev board. This, of course, means there’s not a lot of pins to play with – there are only four I/O pins, and one of them is connected to ground by a LED. That leaves only three I/O pins, but [danjovic] managed to put seven different cheats in his project using diodes and something that is almost charlieplexing.

If you’re wondering, this is a very inexpensive project. [danjovic] is using a Chinese digispark clone, a handful of 1N4148 diodes, and a few tact switches. Anyone with a well-stocked part drawer or a tenner on eBay could build this. If you want the proof of work for this project, you can check out the demo video below.

Open-Source Laser Cutter Software Gets Major Update, New Features

July 17, 2016 by Donald Papp 27 Comments

The LaserWeb project recently released version 3, with many new features and improvements ready to give your laser cutter or engraver a serious boost in capabilities! On top of that, new 3-axis CNC support means that the door is open to having LaserWeb do for other CNC tools what it has already done for laser cutting and engraving.

LaserWeb3 supports different controllers and the machines they might be connected to – whether they are home-made systems, CNC frames equipped with laser diode emitters (such as retrofitted 3D printers), or one of those affordable blue-box 40W Chinese lasers with the proprietary controller replaced by something like a SmoothieBoard.

We’ve covered the LaserWeb project in the past but since then a whole lot of new development has been contributed, resulting in better performance with new features (like CNC mode) and a new UI. The newest version includes not only an improved ability to import multiple files and formats into single multi-layered jobs, but also Smoothieware Ethernet support and a job cost estimator. Performance in LaserWeb3 is currently best with Smoothieware, but you can still save and export GCODE to use it with Grbl, Marlin, EMC2, or Mach3.

The project is open to contributions from CNC / Javascript / UX developers to bring it to the next level. If you’re interested in helping bring the project even further, and helping it do for 3-axis CNC what it did for Laser Cutting, project coordinator [Peter van der Walt] would like you to head to the github repository!

We recently shared a lot of great information on safe homebrew laser cutter design. Are you making your own laser cutting machine, or retrofitting an existing one? Let us know about it in the comments!
