Ants walking through IR gates manipulate the Auduino synth program. John spotted this at the RobotFest / Mid-Atlantic Mini Maker Faire. He writes -
I went to the RobotFest / Mid-Atlantic Mini Maker Faire yesterday. I saw this awesome project and thought you might like to put it on the blog. Basically it’s an ant farm with optointerrupts. When the ants walk through the lightpath, they modify the audio output. The maker’s name is Adam Franchino, and he was there with some of his classmates from the Maryland Institute College of Art (MICA) His website is adamfranchino.net.
Tonight, Saturday 4/24/2010 – 10pm ET – “Ask an Engineer” – Adafruit’s weekly LIVE video chat! What is “Ask an engineer”? From the electronics enthusiast to the professional community – “Ask an Engineer” has a little bit of everything for everyone. If you’re a beginner, or an seasoned engineer – stop in and see what we’re up to! We have demos of projects and products we’re working on, we answer you engineering and electronics questions and we have a trivia question + give away each week. To see previous chat event videos, please visit the forums.
The Apple II has 2 graphics modes. Low-resolution mode, or LORES as the cool kids call it, supports 40×40 pixels with 16 fixed colors. The colors are bizarre – lots of blues but kind of short on reds. Two of the colors are the exact same shade of gray. The other mode is high-resolution mode (HIRES) which gives 240×192 pixels and 6 colors. But you can’t just put any color anywhere you want. You kinda lose half your horizontal resolution once you start using color and even then you can’t just put a green pixel next to an orange one. It’s unbelievably complicated. I wrote software on the PC to turn Twitter avatars into both LORES and HIRES graphic representations. The result is a cool 8-bit vibe, and in many cases the graphics are distant abstractions that bear little resemblance to the original image.
I really love cheat sheets. In a lot of cases they can take the place of an entire manual. So I was surprised, given its popularity that I couldn’t find a single-page reference for the arduino online. I tried to make a sheet that captured all the things I hit the reference for while programming. What data type does the millis() function return? How long till that overflows again? How large can a long get? What baud rates can the serial handle?
The 2010 Bent Festival will take place at 81 Front Street in Dumbo (Brooklyn, NY), April 22-24, 2010. The festival space has been generously donated by Two Trees.
The Bent Festival is an annual art and music festival celebrating DIY electronics, hardware hacking, and circuit bending. Each year we invite artists from across the country and around the globe to perform music with their home-made or circuit bent instruments, teach workshops to adults and children alike, create beautiful art installations and to generally come together, face to face, and showcase the state of the art in DIY electronics and circuit bending culture.
The Twitwee Clock is a modified Cuckoo Clock that wirelessly connects to the internet and constantly checks for new status updates or search results from the Twitter API. New Tweets are displayed on the built-in display in near-realtime accompanied by the charming yet obtrusive call of a mechanical cuckoo poping out of the clock.
The clock could monitor any twitter stream or search, so it could for example inform the user about new tweets in his personal timeline. In exhibition context however it is configured to react on self-referenced tweets. If “TwitweeClock” is mentioned in any tweet, the tweet is displayed on the built in screen and the cuckoo mechanism is triggered.
These drawings show the construction of four novel toys made from circus balloons that will prove highly fascinating. Fill the balloon with hydrogen and attach to it a postcard bearing your name, and a request to return it from whatever point it falls to earth. Thus you can learn in what direction and how far it travels. Another balloon, equipped with a gondola will float in the air like a wartime captive dirigible. The aerial torpedo which zips up through the air is made by affixing fins to an air-filled balloon. The unique air boat cuts through the water under power of air exhaust from blown up balloon.
RoboGames invites the best minds from around the world to compete in over 50 different events. Combat robots, walking humanoids, soccer bots, sumo bots, and even androids that do kung-fu. Some robots are autonomous, some are remote controlled – but they’re all cool! As an open event, anyone can compete – this means you. Buy tickets now! The 7th annual RoboGames will be April 23-25th, 2010. The results for 2009 are available, as are the academic research papers.
