Fubarino Contest: Single PCB Synth

December 23, 2013 by 6 Comments

fubarino-contest-synth

Here’s a musical entry for the Fubarino Contest that turned out to be rather delightful. First, [Mats] shows off his musical knowledge by using the notes H, A, and D to play the chord that unlocks the Easter eggs. What’s that you say? There’s no H on your keyboard? You’re wrong. In the German music tradition B natural is known as H. This is what allowed Bach to write a tune that spells his name.

[Mats] is hacking on his PlingPlong synthesizer. The first Easter egg—which you can see in the clip after the break—launches with the H-A-D chord in the lower octave, spelling out our URL on the 7-segment displays. But we prefer the second egg, launched with the chord in the upper octave, which is shown above. It uses the 3×5 LED grid to scroll out the address; in this still image an H is displayed.

Fubarino Contest: Network Nodes, Door Lock, And Smoker Controller

December 23, 2013 by No comments

fubarino-contest-nodes-lock-smoker

Here’s a round-up of three different Fubarino Contest entries; a video of each is available after the break.

On the upper left are the beginnings of a network node monitoring system developed by [Stephane]. When the network checks the weather, it may determine that it’s far too harsh outside and time to go in to see what’s new on Hackaday. There’s only sparse information available on the hardware. Each node uses an ATtiny84 and an RFM12B—different sensors connected to each are used to build up the network’s data collection capabilities.

In the lower left is [Brett’s] Bluetooth door lock controller. The Arduino, a cheap Bluetooth module, and a relay board make up the base station which will eventually connect to an electronic lock. [Brett] uses a smart phone to punch in the access code, and entering “1337” four times in a row unlocks the Easter egg, displaying our URL on the character LCD. Here’s the code repository for his project.

To the right is the display for [Andy’s] smoker controller used for cooking. He already had some hidden features on the controller used to calibrate the thermocouple. For the contest, he simply added an additional button to extend the original menu access method.

Fubarino Contest: The Problem Of Being Very Good At Foosball

December 22, 2013 by 4 Comments

hachaoay [Sebastian] works at an engineering company testing car ECUs, head units, and all the confusing wiring harnesses found in the modern-day automobile. It’s good work, but not exactly fun, so [Sebastian]’s bosses bought a foosball table so the employees could unwind. The foosball tables have been there for several years, and now everyone at the company is really, really good at twirling little football players on a stick. With their current rule set (at least 6 goals and 2 goals ahead), matches last at least twenty minutes.

[Sebastian] came up with a solution to this problem: a KickerClock – something between a chess clock and an automated score keeper for foosball. The device has two seven-segment displays for each team, and a countdown timer for both of the four and a half minute rounds. All the documentation is up in [Sebastian]’s Google Drive, and he plans on adding a few neat features such as automated score keeping.

The easter egg for this submission? The buttons for scoring each goal are used as combination lock. By scoring eight black team goals (H=8), one silver team goal (A=1), three black goals (C=3), and eleven silver goals (K=11), the Hackaday URL shows up on the seven-segment displays. Extremely well hidden, and a great way to efficiently waste time at work.

Video of the KickerClock, and the easter egg, available below.

Fubarino-Contest: 1980’s CD Player With MPD

December 22, 2013 by 6 Comments

[Ronald] had to scramble to get his submission in, but we’re glad he did. His demo video shows the display of a 1980’s CD player working with Music Player Daemon. It’s really just the original display itself that works, but the project is not yet finished. However, is far enough along to show our URL when a track reaches the 22:00 mark.

The display is driven by an ATmega32 chip which uses a USB connection to receive commands from the computer running MPD. [Ronald] had troubles figuring out how to send int values over USB so he hacked his own protocol that just uses the LSB of each byte coming over the bus. After the break you can see the video, and read the description which he included with his submission. There is also a code package available here.

Fubarino Contest: Minecraft, Zelda, Arduinos, And Hackaday

December 22, 2013 by 17 Comments

song

In a clever bit of pandering to the gamer crowd for the Fubarino Contest, [Laurens] has combined The Legend of Zelda, Minecraft, and an Arduino to create something really, really cool.

[Laurens] cobbled together an Arduino, MIDI connector, and LCD display that will read a MIDI keyboard and detect when one of the songs from Ocarina of Time/Majora’s Mask is played. The Arduino then plays back the song slower and longer, just like in the game.

Here’s where things get cool: Since [Laurens] has an Arduino that knows when an OoT/MM song is played, he can have the Sun Song control the lights, or the Song of Storms turn his sprinkler system on. He chose to pipe all these commands into Minecraft, where the Song of Healing gives some health to the Minecraft character, the Song of Storms controls the rain, and other awesome mashups of Zelda and Minecraft.

This project offers more than enough to stand on its own, but [Laurens] also added a Hackaday easter egg. When playing the letters HAD in ASCII on the keyboard, our favorite URL shows up on the Arduino and inside Minecraft.

Here’s an image gallery and the source code (dropbox, so don’t spam it) for [Laurens]’ awesome project.

Fubarino Contest: Persistence Of Vision Clock

The best part of these contests is that we get people to actually show off what they’ve been working on! Check out the POV clock which was sent in by [Taciuc]. He doesn’t have a webpage for it, but he did send a video which you can see after the break.

The project is a home-etched PCB with a long row or surface mount LEDs. The board is spun by a stepper motor which takes a little while to stabilize. But once it does it’s a twirling package of awesomeness. A PIC 16F628 drives the device, with a separate RTC chip to keep time. There’s also an IR receiver to facilitate user control. Our URL is displayed on the clock face itself and we think it’s always shown. But there is an easter egg in the code itself. If you try to dump the firmware from the chip you’ll see our web address in the hex output. Here’s his project archive if you want to the HEX, ASM and DipTrace schematic.

Fubarino Contest: Hackaday Tells You You’re A Terrible Pilot

December 21, 2013 by 6 Comments

[Mikko] is in to flying F3B racers – remote control airplanes with a three meter wingspan. These races require the pilot to know how much time he has left, and when flying a remote controlled airplane to the edges of visual contact, it’s just not possible to look down and check a stopwatch.

To solve this problem, [Mikko] created a talking F3B timer to announce the flight time and how much time is left in 30 second increments. It’s based on a WTV020 audio module that plays audio from an SD card.  Right now it’s just in the prototype phase, but he does have some code and documentation online.

As for the easter egg, [Mikko] programmed his timer so that if the flight lasts exactly 33 seconds (with millisecond resolution), the Hackaday URL is displayed on the Nokia LCD. We’re betting a flight time of 33 seconds would be highly correlated with a horrible malfunction and the loss of a thousand dollar airframe, so we’re more than happy to cheer [Mikko] up if he eventually sees this easter egg in the field.

Video of the talking timer speaking Finnish below, and a video showing off what these huge sailplanes can do right here.
