Fresh hacks every day
When [Matt] started building his multirotor helicopter, he was far too involved with building his craft than worrying about small details like how to actually control his helicopter. Everything worked out in the end, though, thanks to his homebrew RC setup built out of a USB joystick and a few XBees. After a few initial revisions and a lot of chatting on a multirotor IRC room, [Matt] stumbled … [Read more...]
Just like the clock from Harry Potter, a team of media informatics students at the University of Munich built a grandfather clock that doesn't keep track of time; instead, it keeps track of where everyone is, whether it be their university, work, or in prison. The build uses Android and iOS apps on each team member's cell phone to send their current location to a web server. A circuit built … [Read more...]
[Blair Kelly] has always been interesting in the concept of Remote Operated Vehicles. As soon as he got his hands on an Arduino he began his endeavor to turn an RC vehicle into a land-based ROV. What he's done so far is incredible. Here he's showing off features of the build using a PS3 controller. But it can also take commands from an Xbox 360 controller or an arcade-style steering wheel. We … [Read more...]
[Rui] needed an easy way to play music in several different zones from one centralized location, but he didn’t want to run any new wiring in the process. He figured that the best way to do this would be to stream his music directly to his speakers over Ethernet. Earlier this year, he put together a handful of Ethernet-connected speaker nodes using a few Arduinos equipped with both Ethernet … [Read more...]
Instructables user [zvizvi] was working on putting together a portfolio for his application into Industrial Design school, and thought it would be neat to repurpose an old rotary phone that used to belong to his grandmother. He originally had pretty lofty goals for the phone, but eventually pared back his vision to include one-way communications to Twitter. After gutting the phone of its … [Read more...]
[Kenneth] built this scoreboard for use at a ballpark that lacks such luxuries. We think this a phenomenal application for his skill and his pocketbook. He laid out PCBs for each digit in Eagle and etched them himself, then installed the indicators for home score, visitor score, inning, balls, strikes, and outs in a laser cut case. A pretty beefy battery along with the folding stand make this … [Read more...]
DPAC, the Dynamically Programmable Alarm Clock, goes far beyond what you would expect an alarm clock to do, yet we find all of its features useful. You can see there are four buttons at the bottom that control the menu scrolling. The second from the left currently reads "Sync", a feature that the clock uses every 10 minutes but can be forced manually. This will check your Google Calendar, schedule … [Read more...]
