Fresh hacks every day
[Mikal] wanted to create an awesome electronic wedding gift for his friend who was moving to France. After experimenting with a few things, he settled on creating a puzzle box that would only open in a certain location. Since his friend introduced him to the Arduino, he fittingly used one in the design, along with a serial GPS module and a mini character LCD. The box itself is locked using a … [Read more...]
[etgalim] works in Solidworks extensively and wanted a more intuitive way of rotating objects onscreen. To do this, he created a mouse that responds to rotation. He put a 3D compass module inside an old mouse and wired it up to an Arduino. The Arduino then relays the I2C sensor data to the computer. So far, he has a Processing script that uses the mouse to rotate a cube, but eventually he wants … [Read more...]
OpenMoko, the company behind the FreeRunner open-source phone, released their latest product today: WikiReader. It's a small mobile device for browsing Wikipedia. Rather than use a wireless network to pull data off of the web, it has local copy of the database on a 8GB microSD card. This approach has been used before, and it lets the WikiReader be compact and really cheap. It uses a Kindle-esque … [Read more...]
We've covered sequencers before, but reader [Johan] sent in his latest project that is much more minimalistic approach. Dubbed the BBox, he based his drum generator on an Arduino and an LCD display. Rather than synthesizing sound, the Arduino just outputs MIDI which is then interpreted by his Roland Juno-D. In building the device he used a favorite trick of ours to keep the interface clean. He … [Read more...]
The Arduino makes a great platform for alert systems because it doesn't need additional parts, other than an LED or motor. [Torchris] made email notifier, and used an Ethernet shield to make it standalone. The Arduino polls your POP server seeing if there are unread emails. POP is an incredibly simple protocol, even simpler than HTTP; this made it easy to communicate with, even with little … [Read more...]
[Sebastian Tomczak] was borrowing a homeade muon detector from his friend, and managed to hook it up to his computer through an Arduino. The detector itself uses 3 fluorescent tubes to detect radiation. Three separate tubes are used in order to filter out terrestrial radiation; cosmic radiation will fall in-line with the tubes and pass through at least two of them, whereas terrestrial radiation … [Read more...]
With the transition to digital TV, the FCC has abandoned the old analog format. Luckily, you can take advantage of this and set up your own analog TV station. The FCC has a tool on their site to see what channels are open in your area to broadcast in. To broadcast, you need a TV transmitter, but cheap short-range models can be found on eBay or made at home [pdf]. Once you have a transmitter, you … [Read more...]
