With the Intertubes atwitter about the finalist – and winner – of the Hackaday Prize, it’s only fitting the rest of you get to hear what the judges thought about the finalists.
We had some amazing judges combing over these projects, ranging from people who have told Congress they could shut down the Internet at will to a Dutch guy that just figured out how to order a plain hamburger in the Munich train station. Really, really smart people. Here’s what they had to say about each project:
Kickstarter isn’t the solution to every manufacturing hurdle, you know? Crowdsourcing—everybody’s favorite cliché to invoke after sharing their less-than-half-baked merchandise idea—has expanded to include yet another variation, and is currently rocking [Max Thrun’s] BeagleBone GamingCape thanks to [Jason Kridner]. If the cape looks familiar, it’s because we featured it earlier this summer, when [Max] created it as part of TI’s Intern Design Challenge.
Here’s how it works. Rather than asking strangers to place pre-orders (let’s admit it, that’s ultimately how Kickstarter functions), CircuitHub campaigns work as a group-buy: upload your KiCad, Eagle or Altium design and a BOM, and you’re on your way to bulk-order savings. As [Kridner] explains in his blog post, you’ll have some finagling to do for your campaign to be successful, such as choosing between prices at different volumes, projecting how many people need to buy in as a group, etc. When he sourced the parts on his own, [Kridner] spent nearly $1000 for a single GamingCape. The CircuitHub campaign, if successful, would land everyone a board for under $100 each—and it’s assembled.
Who needs Kickstarter; that’s hard to beat.
A lot of people have used ESP8266 to add inexpensive WiFi connectivity to their projects, but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266. [Oscar] wrote a server script in Python that communicates with firmware running on the Arduino. The Arduino connects to the server on startup and listens for a “reboot” command.
When the command is received, the processor resets and enters the bootloader. The python script begins streaming a hex file over WiFi to the ESP8226, which relays it to the Arduino’s bootloader. Once the hex file is streamed, the microcontroller seamlessly starts executing the firmware. This method can be used with any AVR running a stk500-compatible bootloader.
[Oscar]’s writeup is in Spanish, but fortunately the comments in his Python and Arduino code are in English. Check out the video (in English) after the break where [Oscar] demonstrates his bootloading setup.

The Grand Prize winner of the 2014 Hackaday Prize is SatNOGs. The project is a thrilling example of the benefits of a connected world. It opens up the use of satellite data to a much wider range of humanity by providing plans to build satellite tracking stations, and a protocol and framework to share the satellite data with those that cannot afford, or lack the skills to build their own tracking station. The hardware itself is based on readily available materials, commodity electronics, and just a bit of 3D printing.
The awarding of the Grand Prize caps off six-months of productive competition which started in April with a first round reaching to more than 800 entries. Once the field had been narrowed and sent on to our judges the narrowed it to just 50 projects vying for a trip into space (the grand prize), industrial-grade 3D printer and milling machine, a trip to Akihabara electronics district in Japan, and team skydiving.
You already know this but such an accomplishment is well worth mentioning again!
The ChipWhisperer is a hardware security testing platform that allows developers to explore side-band and glitch vulnerabilities in their hardware projects. The existing technologies for this type of testing are prohibitively expensive for most products. The availability of this tool plays a dual role of helping to inform developers of these potential attack vectors, and allowing them to do some level of testing for them.
The form and function of the PortableSDR move forward both Software Defined Radio and Ham. The SDR aspect fully removes the need to use a computer. The wireless functions provided can be called a modernization of portable amateur radio hardware.
Inspired by the future-tech item found in the Star Trek franchise, the Open Source Science Tricorder uses currently available technology to produce a handheld collection of sensors. The design provides modularity so that the available sensors can be customized based on need. Equally importantly, the user interface gives meaning to the data being measured, and allows it to be uploaded, graphed, and otherwise manipulated on the Internet.
Raman Spectroscopy is used to help determine what molucules are found in test samples. One example would be determining possible contaminants in drinking water. These tools are expensive and the ramanPi project will mean more labs (at University or otherwise) as well as citizen scientists will be able to build their own spectrometer. One particularly interesting aspect of the project is the parametric 3D printer file used for mounting the machine’s optics. The use of this technique means that the design can easily be adapted for different types of lenses.
With the great success of these five projects, and the potential that Open Design has to move the world forward, we hope to host another round of The Hackaday Prize in 2015. When you’re done congratulating the winners in the comments below, let us know what you think the subject of the next challenge should be.
Hackaday would like to thank the generosity of our sponsor, Supplyframe Inc., who supported the cost of all prizes. Supplyframe is Hackaday’s parent company and their values are closely aligned with our own.
The Kankun smart plug is an inexpensive device that lets you switch an outlet on and off over wifi. The smart plug only works with an Android or IOS app that ships with the device, which limits its usefulness to turning things on and off from your phone.
In an attempt to make this device more useful, [LinuxGeek] probed the device with nmap and discovered that it runs OpenWRT. After trying various common default passwords he discovered the login was root/admin. While [LinuxGeek] hasn’t sniffed the protocol yet, others have hacked it a bit further. The plug apparently uses UDP packets to communicate with the Android app, but the packets are unfortunately encrypted.
Rather than hack at the protocol, they wrote code that toggles the GPIO pin from a CGI script and developed a small Windows application that hits the CGI script for simple control from a computer. There’s also a Google+ group where more information and a couple other hacks for these plugs are posted. For $20 (from AliExpress) and with a bit of hacking, this smart plug could be a great way to add wireless control to a home automation system.
The Hackaday Prize is here! We know you can’t all be here with us in Munich so we’ve set up a live stream link for everyone to follow along at home. If you tune in now, you can catch some of the talks at our open hardware event!

We had a few very cool workshops at our party in Munich today, with Moog synths, robotic arms, Linksys routers splayed open on a table, and Club Mate flowing like water. We’re wrapping the workshops up right now and the kegs are being tapped. Before that, though, it might be a good idea to show off all the other Hackaday Prize projects that showed up today.
The M.A.R.S. Rover, a 3D-printed rocker-bogie robot showed up around noon. I didn’t see it driving around, but there will probably be video up later.
Also shown was the AutoCut robotic lawn mower. No blood was shed today.
[Mario] was cool enough to fly in and show off the OpenExposer, a laser resin printer that is heavily inspired by the RepRap project.
Pictures below.
