Valentine’s gift counts the days spent together

Posted: February 18th, 2011, 2:03pm MST by Mike Szczys

[Vegard Paulsen] dug deep down to the romantic geek at his core and built this box that counts the days he’s spent together with his Valentine. As you can see, it uses a four-digit seven segment display installed in the lid of a wooden box. An Arduino mini is responsible for driving the display, but [...]
Sniff Ethernet with a throwing star

Posted: February 18th, 2011, 1:02pm MST by Kevin Dady

[Michael Ossmann] came up with a nifty little device that arranges RJ48 plugs into a plus shape for the intent of sniffing Ethernet packets, and named it the “Throwing Star LAN Tap”. While the original design worked fine it does suffer some limitations such as being limited to 10/100 base networks, and one way only. [...]
Bluetooth-enabled Wii nunchuck

Posted: February 18th, 2011, 12:01pm MST by Mike Nathan

The wireless controller for the Nintendo Wii has been used in many a hack due to its simple to use Bluetooth interface. The nunchuck portion of the controller however, has always required a physical tether to the wireless controller, or an aftermarket wireless dongle. [Rousselmanu] is looking to change that with his Bluetooth-enabled wireless Wii [...]
Brain Car Interface

Posted: February 18th, 2011, 11:03am MST by Kevin Dady

The AutoNOMOS labs project has found a new way to maneuver its vehicles, your brain. We have looked at a previous version that uses a mostly computerized van under remote control from an iPhone. This one however, named “Brain Driver”, places the operator in the driver’s seat with an EEG strapped to their head. Going [...]
Simple household status system

Posted: February 18th, 2011, 10:01am MST by Mike Nathan

[BrianH] decided that he no longer wanted to venture outside on cold or rainy days just to check if the mail had come, so he built himself a notification system that would alert him if the postman had stopped by. Additionally, he admits to being forgetful on occasion and wanted a way to monitor whether [...]
Molded parts: Prusa Mendel in 30 minutes

Posted: February 18th, 2011, 9:00am MST by Mike Szczys

This set of white RepRap parts were created in molds, instead of being printed by another RepRap. [Mark A. Ganter] of the University of Washington admits that this breaks the idea of a 3D printer that is self-replicating. But the molds – which were created by tweaking Prusa Mendel parts to be mold friendly – [...]
8-bit MIDI synthesizer

Posted: February 18th, 2011, 8:02am MST by Mike Szczys

[Derek Enos'] toils are starting to yield results. He’s been working on an 8-bit synthesizer that is MIDI controlled which he calls the deMIDulator. As he demonstrates after the break, the device has sine and square wave functions that produce quite a pleasing sound. But it also offers the option to record your own samples which [...]
Cyborg camera mask

Posted: February 18th, 2011, 6:05am MST by Kevin Dady

[Ryan] whipped up this robotic masquerade mask to wear to his wife’s art opening / masquerade party, and its pretty wild. The prominent feature of this mask is a scavenged lens assembly from a typical point n shoot style camera, which is still connected to its electronics so it can go through its off and [...]
NES Paul game controller

Posted: February 18th, 2011, 5:11am MST by Mike Nathan

[NeoTenchi] wrote in to share the new game peripheral he built, dubbed the NES Paul. The ultimate goal of the project was to build a NES-styled controller for an upcoming game he is working on, tentatively titled 8-bit Hero. The guitar is constructed primarily from wood, as well as some scrounged bits he had around [...]
