• Giving an old arm new life
[Jarek] found a non-functional robotic arm sitting around and wanted to get it working again. By adding a few custom boards to an Arduino he managed to do just that.
The arm is driven by six stepper motors, each having four control wires. To handle all of these [Jarek] used TIP120 transistors to protect the controller. [...]
• Bluetooth bracelet hacked
[Jeffery] hacked the Bluetooth standard in order to use this bracelet as a custom display. He took up our challenge to hack the device when we first saw it back in February.
In order to display his own messaged he looked into how the HFP is implemented in the Bluetooth stack. The details are shared in [...]

This collection is normally $1000 so I thought to myself “hey, pretty good deal…let’s post it!”. You can get it Here. Be quick to grab it before the deal ends! It’s a 2GB download by the way…be patient After all, it has over 800 tracks. If you like classical music and you miss out on this deal, then you should kick yourself at least 800 times.

• Better temperature readings using an aspirated thermometer
Unlike regular thermometers that can get incorrect readings because of the sun’s heat, shading, and airflow, aspirated thermometers isolate the temperature sensor from precipitation and the sun, while providing constant air circulation. Take ten 1-write T2SS boards and combine them with DS18B20s and you’ve got yourself the start of an aspirated thermometer. A foot of [...]
• Accessing BGA pins
[Philip] developed a method of tracking down the pins of a Ball Grid Array. He wanted to do so in order to add USB host functionality to his HP Jordan 720. The method doesn’t directly connect to the BGA but instead finds a via or other access point to serve as a solder point. He [...]

• 2600 game jukebox
[Yuppicide] sent us a link to a photo album of an Atari 2600 modified to play ROMs stored inside. We did some digging around and have an idea of what’s going on. It seems that the creator, [Victor] has taken his Atari 2600 cartridge emulator one step further.
Previously, he had replaced the chip in an [...]
• [techknott]’s portable dreamcast
[Sydney] sent in this fantastic portable Dreamcast, built by [techknott], in response to the one we posted yesterday. While we agree, this one is much more polished, we want to point out why the post yesterday is more Hack A Day material. Sure, it looks more “hackish”, but that’s not what we are referring to. [...]

• Interactive beer pong table
Do you find that beer pong is too dull on its own to keep your attention? Do you require flashing lights to accentuate your imbibing?  Here’s the perfect solution. Make an interactive beer pong table. It didn’t take much to sell us on the idea. We think everything needs a few more lights.
The idea is that [...]
• Social Media HUD
After [Gregg Benjamin] read our story about a simple physical email notifier, he decided to test his skills and add some touches of his own. Rather than limiting his notifier to just email, he has added support for displaying Pandora Radio songs, Facebook notifications, and email all to a LCD. He even has included code [...]

I personally love the game Borderlands. A first person shooter with RPG elements and multiplayer co-op equates to “awesome”. Luckily, a Borderlands 2 WILL be coming out in the future. Mike Neumann, the creative director of Gearbox (makes of Borderlands) pretty much summed that up in his interview with VG247. Mind you, this isn’t new news or anything, but for those who haven’t heard about it, well, now you know! Hopefully it’ll be longer than its predecessor.

• Monitor Keg volume, CO2, and temp
[Jean-Michel] tipped us off about his beer keg monitoring setup. It can tell you how much beer is left in each keg, how much carbon dioxide remains in the canister, and it can monitor and regulate temperature.
An Arduino mega is the brain of the system. A shield was built to interface force sensors, measuring the [...]
• Fabric display
[Eli] is sharing the building details on her fabric based display. For lack of a better name she’s calling this a fabric Lite-Brite. This is because LEDs can be added anywhere to spell out a message or create a simple drawing.
The device consists of a positive bus of conductive thread sewn onto a regular piece [...]

• BiDi Screen, on (and off) screen multitouch
MIT is debuting their latest advancement in technology, a multitouch screen that also functions as a gestural interface. The multitouch aspect is nothing new, the team explains how traditional interfaces using LEDs or camera systems do work, but fail to recognize gestures off-screen.
Gestures are a relatively recent highlight with the introduction of projects like Natal [...]
• Embedded games: Rogue
Here’s a handheld version of Rogue. Rogue is one of the first graphical computer games and takes the player through a dungeon-exploring adventure. [Manuel] built this around a PIC 16F876 microcontroller and a KS0108 graphic LCD screen.
Hot on the heels of the pixellated Mario game, these embedded handhelds make for fun projects and great gifts. [...]

• The Harlequin project
This impressive little mod is quite fantastic really. [pakkei] has constructed the Harlequin, a home-made version of the Microsoft courier. This was a stock Dell mini9. Now, coupled with a display link touch screen monitor that happens to be identical in size and resolution to the original, it has become a new device. He has loaded Windows7 [...]
• Remote bike mountain
The Remote Bike project, caught our eye today. Inspired by “cliff hangers” on the tv show “The Price Is Right”, [atduskgreg] has built his own version. In this version, the bike on the mountain makes progress, or slides back down the mountain based on the speed you pedal.  If you maintain your target speed long [...]

I have now finished watching all of Yu Yu Hakusho — a series I had started years ago but never finished. This anime was excellent. In fact, Bleach was accused of being a copy of Yu Yu Hakusho originally, though I personally do not think they’re too similar at all. It’s 112 episodes long and here’s some more info on it:

Genres: action, comedy, drama, supernatural, tournament
Age rating: Teenagers (May contain bloody violence, bad language, nudity)
Plot Summary: One day, 14 year old Yusuke Urameshi suddenly finds himself dead, having died pushing a child out of the way of oncoming traffic. Since he has such a bad personality, even the Spirit World was caught by surpise that he would sacrifice himself. Yusuke soon finds out he wasn’t supposed to die and has a chance for resurrection and bringing his body back to life. After being resurrected, Yusuke becomes a Spirit Detective, along with his comrades, and one adventure after another happens, whether it be an investigation or a fighting tournament.
