[Gerben] started on his adventure into the world of electronics about a year ago. His first big project is this magnificent word clock. It’s Dutch, if you’re wondering.
As a web developer, the first thing [Gerben] did was build a web-based mockup of this clock. After that, he went crazy with power tools crafting the wooden frame. Perhaps too crazy, as he forgot the space for the electronics. This oversight was solved by making his own PCBs, first using peroxide and vinegar, then giving up and moving to peroxide and HCl.
The easter egg for this word clock is a scrolling URL when the time is 13:37. A clever egg that is really completely original.
From the looks of the video, the fit and finish of this word clock is beyond anything we’ve seen before. The entire front of the clock is glass, with capacitive touch buttons down by the four-LED ‘minute’ display.
Video below, Pics over here, and all the code and board files are here.
This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!

Last summer, we here at Hackaday participated in the Red Bull Creation Contest. Basically, twelve teams were given webcams and instructions to build something cool. The teams live streamed their build process, and the best of the bunch won a trip to the New York Maker Faire. [Jason Naumoff], the guy behind this build-off is doing it again right now. It’s called The Deconstruction and it pits 50 teams on 6 continents to build something cool while streaming their project to the Internet.
The Deconstruction is a little bit different from Red Bull’s contest – first, the teams don’t have access to ludicrous amounts of energy drinks. Secondly, there’s no set theme for the group entries. It’s a free-for-all build off where teams can make anything they’d like.
We’ve really got to hand it to [Jason] for pulling this off. He MC’d the Red Bull Creation Contest live stream – nearly all 72 hours of it – and was entertaining right up to the very end. You can check out the official stream on the main Deconstruction site, or you can check out the individual team streams here.
What can you do with ten buttons and ten lights? A lot.
[Andrew] and [Nathan] found a collection of Hale Research keypads being thrown out, and decided to host the Keypad Contest. The goal of the contest was to create something nifty using the ten buttons and ten lights on the keypad, and an ATtiny2313 that replaced the original 8051-compatible microcontroller in the device.
[Andrew] wanted to try making PCBs with his home-built CNC machine, so he milled out USBtinyISP programmers for the ATtiny2313. Then he gave out eleven development kits to a group, and explained how to develop on the hardware.
After a month of hacking, seven people completed projects. The winner was an internet radio controller, which had the keypad sending serial data to a TP-Link WR703N router. The router used a USB sound card and OpenWRT firmware to stream music. The runner up was a timing game called “Capture”.
The contest write up has details on all seven projects. [Andrew] and [Nathan] were successful in getting software engineers to try hardware with this contest, resulting in some neat hacks. After the break, check out a video demo of the internet radio controller.

This soldering nightmare is a configurable RFID tag which has been built from 7400-series logic chips. The beast of a project results in an iPhone-sized module which can be used as your new access card for security systems that uses the 125 kHz tags. The best part is that a series of switches makes the tag hand programmable, albeit in binary.
Of course this is an entry in this year’s 7400 Logic Competition. It’s from last year’s winner, and he’s spent a lot of time documenting the project; which we love. We were surprised that this many chips can be powered simply by what is induced in the coil from the reader. This is just one of the reasons the 7400-series have been so popular over the years. After working out the numbers, a 64-bit shift register was built to feed the tag ID to the encoding portion of the design. There were many kinks to work out along the way, but once it was functional a surface-mount design was put together resulting in the final product shown off in the video after the break.

The people have spoken. Hackaday has won the Redbull creation challenge by popular vote. Despite a few bumpy spots in the voting process, our project, the Minotaur’s Revenge (gameplay footage around the 2min mark in the video), got the most votes from the public winning us $5000 for our hackerspace and a trip to the World MakerFaire in New York.
Thanks to everyone who was able to actually vote, and we totally understand about those who didn’t.
Our Project: “Minotaur’s Revenge”
We built two giant marble mazes. The maze itself is all mechanical, with a 2 person team controlling x and y axis. The fun happens though when you hit buttons to activate magnets and traps on the other team’s table.
Check out the Live Stream. Nothing is happening at the moment, but a couple of dedicated Hackaday fans are checking out an empty couch. We have a very strange readership.
[sonofabit] recorded the last 8 hours of the build at 1fps and made a time lapse video. It’s an hour long, and we thank [sonofabit]’s CPU for all its hard work. You can also check out the video after the break.

Tonight at 6pm pst, the people at RedBull will be announcing the theme for the 72 hour build-off. We’ve cleaned our space, set up the cameras, and tried to get a good night’s sleep. We’re all ready to kick some ass and would love it if you would join in to watch and even chat with us during the build. You should be able to watch all of the teams at the red bull contest web site. Though you can also just tune in to us at the link below, or on the sidebar.
During some of our team meetings we decided that watching a live stream of us hunched over some device for 72 hours would be extremely boring. To help remedy this, we have been contacting people all week to arrange proper amusement. We have graffiti artists, dancers, and some other miscellaneous things(possibly fire breathers?) in the works to help break the monotony. You’ll see a board labelled “EVENTS” in the bottom left of our stream. This should help keep you notified when the next bit of amusement shall arrive.
If you want to just watch the teams individually, there’s a list of each of our channels after the break.
