Pre-spun hard drives

This device is lovingly called the SPINmaster. [Linux-works] built it to spin up multiple hard drives before the motherboard starts up. It detects the power-up from the PSU and uses a relay to hold the motherboard in reset, indicated by the red LED. Each of four relays then spins up a hard drive and illuminates the green LED when ready. Once all green lights come on the reset relay shuts off and the bios starts up. This type of staggered startup takes a lot of the load off of an under-powered PSU. He’s posted firmware and there’s a schematic available too. We took a look at his video but there’s not much to see as it’s just the inside of the machine while it boots up.

Pipe heating with an ATMega8

[Viktor] wanted a system to keep his pipes from freezing.  The common method of using heat tape works pretty well, but can be wasteful. Many people just turn it on for the entire winter. [Viktor] wanted to automate the heat tape’s power so that it only activated during times that the pipes could actually freeze. To do this, he rigged an ATMega8 to a temp probe and is using it to control an ATX power supply. Pretty slick [Viktor].

Repurposing a click wheel

We think the click wheel is the biggest contributor to the success of the original iPods. The devices were a brick with a monochrome screen but the user interface was slick and easy to use. [Jason] decided he wanted to add a click wheel to his own project. After using a logic analyzer he discovered that it doesn’t implement a common protocol such as I2C, perhaps a deliberate move by Apple to keep the controller under wraps? He managed to get past this hurdle, as seen in the video after the break, by bit-banging the data in from the click wheel and then reverse engineering the protocol.

It’s connected to an AVR ATtiny88 with feedback shown on a character LCD screen. We’re glad that [Jason] tipped us off about this, but he doesn’t have any code available yet. We love to dive into the source so the sooner he gets it up the better! We’ve got an old 3rd generation with a bad board that is begging to have the wheel ripped out of it, not to mention the dirt-cheap replacements available on ebay.

Arduino to Nintendo DS interface

[Hounjini] was poking around at the Game Boy Advanced bus of his Nintendo DS lite and figured out how to use it to connect an Arduino to the DS. For testing he’s soldered an IDC plug to the cartridge cover pin interface but this only requires four connections. The Arduino can both send and receive data from the DS lite as shown in the example videos after the break. The data access is made possible by making the Arduino look like a controller that the DS is happy to talk to.

[Thanks Christian]

European Nintendo downloads: Excitebike World Challenge, Final Fight 3

Excitebike World Rally, having just been released in Japan this week, is now available in Europe, ready to delight players with online, tilt-controlled classic motorcycle racing. Final Fight 3 is also out in Europe this week, with classic dude-punching. We’re starting to wonder — is the worldwide Virtual Console release of Final Fight 3 some kind of abstract promotion for Super Street Fighter IV, which features characters and locales that originated in the Final Fight series? Or is it the Wii’s equivalent of Final Fight Double Impact?

  • Final Fight 3 (Virtual Console: SNES, 1-2 players, 800 Wii Points)
  • “Aha! I Found It!” Hidden Object Game (WiiWare, 1-4 players, 500 Wii Points)
  • Excitebike World Challenge (WiiWare, 1-4 players, 1,000 Wii Points)
  • Snakenoid (DSiWare, 1 player, 500 DSi Points)

Dragon Quest VI remake approaches 1m Japanese sales in first week

The debut of the Dragon Quest VI remake for DS proves that a Dragon Quest game doesn’t have to be entirely new to sell like crazy in Japan — just new enough. In its first week at retail, January 25-31, the new version of the classic Super Famicom RPG sold 906,458 copies, according to Media Create, making it by far the top-selling game of the week.

A pair of other newly-released RPGs also did quite well: the PS3 version of tri-Ace’s shooty-RPG End of Eternity (we call it “Resonance of Fate“) landed in second place on the weekly software chart with 118,088 units sold (the Xbox version charted respectably at #8, selling 27,048 units) and Ar Tonelico 3 hit #4 with 81,633 copies sold. Even the Japanese release of MAG managed to make it into the top ten!

See the complete weekly top ten sales list after the break.

Antique Jukebox Audio Streamer

Reader [Jimmy] sent us some info about his recently completed antique radio to audio streamer conversion. The electronics from the original radio were too far gone to repair, but he took the time to pull apart modern components to provide a polished looking finished project without losing the antique feel. We like it, but we are just suckers for that old time look. Check out his blog for more photos.

Ask a winner updates day 5: Answers

Not too long ago we asked our readers what they would like to hear about from the PUSH N900 winners and their hacks. We got some silly questions, and some serious, we asked both and now the PUSH teams have answered.

The day has passed, the party is gone, and all that’s left is the final interview. The Light Hack Crew gave us a somewhat shorter response then what we were used to, but it turned out to be just as sweet.

>Thank you for taking the time to answer some questions for HackaDay. We love when a hacker is willing to share their work with us.

>How did you and your team get together? Any fun backstory you care to share?

LIGHTHACK CREW is a trio of 3 crazy coconuts from Perth, Australia . [Dave] and [Tom] have been friends from way back, and [Sharna] is a friend from way, way back,

>Have you and your team worked on any other projects? Cellular related projects? N900 projects?

No this is our first one together.

>What was your main inspiration for your team’s project?

It was [Tom’s] idea for focusing the project of light graffiti, and that made me think of [Sharna] as she is a graffiti stencil artist.

> How do you think people will react when you finish/release?

People will love it as it is fun to create light graffiti and easy to do, all you need is the hacked N900 and the electronic LED can.

>Do you have any future plans with your team? Continued N900 development? Update your current projects?

Hopefully continued development of the Light Hack software and bring it to other devices

>What do you think of the other winners?

well as a skater, long boards mainly, I’m interested in the soldering skaters team, the others are great too,

>Questions from our commentators.

>What are you thoughts on Arduino? Do you intend to use one in your project?

[Tom] is the electronic genius,­ but I’d say he found the Arduino pretty straightforward.

>How is working with the N900 hardware and software?

Great from the little I have looked at and used, the phone is very powerful, its not running a snapdragon but damn can it multi task! the open source Maemo OS is very cool, the fact that it is linux makes it so much easier to develop for, as so much is setup for it already – SDK installed VM image is the way to go.

>What do you think about the movement of cell phones towards open source software, such as the Maemo? Do you plan to, or have you ever tried Android?

I think its great, I tried the iphone, but objective C was new to me, along with the $100!, haven’t had the time for android yet. But would like to check it out.

>(If you use a secondary power source, example – to run motors) What kind of battery life is expected for your project?

We use 4 AA or 4 AAA batteries at the moment. Im sure we could wire up any sort of battery. The battery life isn’t too bad, as the Bluetooth really only is used when the buttons are pressed, and the LED’s are quite efficient.

>Can we get a list of what you’re using in your project? (example – bluetooth sets, motors, dedicated sensors, etc)

HARDWARE: Bluetooth module, PIC microcontroller

SOFTWARE: I used C, for the language, GStreamer framework for capturing the video, and some basic algorithms for image processing: subtraction and a moving average filter for noise removal.

>And yes, we actually had a reader (Joe) ask the following (feel free to omit)

>How often do you change your underwear? Underwear?

Its 38 degrees im just wearing my boardies J

Thank you again!

Teens like video games (and other stuff you don’t get)

[Stand Up For America]

Your teenage daughter and/or son aren’t kidding around when they say you just don’t get it. You really don’t. You’re not a teenager. You don’t know everything like they do. And one of the things they know is that video games are the bomb. The kids still say that, right?

Anyway, according to a recent Pew Internet & American Life Project study (via MSNBC), 80 percent of teenagers between the ages of 12 and 17 own a gaming console and that around 51 percent of those in the same age group own a portable gaming device. “While younger and older teens are equally likely to have a game console, boys are more likely than girls to have one,” the study reads, pointing out that 89 percent of boys have a gaming console compared to 70 percent of girls.

The study itself focuses mostly on the internet and how the young are connecting (hint: they like laptops and — wait, MySpace?), but it’s a good read if you’re looking to get in touch with the youngsters.
