Finally the 13-year-old on Battlefield 3 will get their comeuppance

[Shawn] sent in his fully adjustable auto-fire mod for an XBox360 controller. It’s pretty simple – just an ATtiny85 soldered to a button with a pot to adjust the rate and switch to turn it on and off. It could have been done with a 555, but this is good enough.

Now one for the PS3 bronies

[Capt-Nemo] loves and tolerates everyone so he modded his 60 Gig PS3 with a bunch of LEDs to display Rainbow Dash’s cutie mark. Yes, it’s from My Little Pony. Don’t judge us. Watch the demo video instead.

How do you organize resistors?

A while ago we saw a neat way to store resistors in a piece of foam with a grid according to the first and third color bands. [Greg] did it another way that just puts a label on a piece of foam. Can you think of a better way?

It’s not a synthesizer, but is it fake?

A lot of people have been sending in this video of [Stephen] turning his kitchen into a synthesizer. We’re thinking he turned a bunch of bowls and cans into an MPC / MIDI controller at best, or it was all done in post. We’ll let our readers duke it out in the comments.

Blinky things spinning very fast

A gracious Hack a Day reader sent in a mechanical television demo he found during late night intertube browsing. We know it’s from a 1992 episode of Computer Club that aired in Germany. It’s four rotating bars of 232 LEDs that will display a standard TV signal. We think it might be time for an RGB LED version of this. Any takers?

Adorable and small portable NES

The Queen of Bondo is back again, this time with an adorably small NES portable, the HandyNES.

When last saw [lovablechevy], she had just finished up her build of a Nintenduo, a build that stuffed an NES and SNES into a single box. The Nintenduo was such a clean build it would be a crime to let her talents go to waste, so [Lovablechevy] finished up one of the smallest NES portables we’ve seen.

The build is based on a top-loading NES with a 3.5″ screen. [rekarp]‘s NES2 composite mod was used to get the NES and screen working together. Two LiIon batteries provide 3 hours of play time (with a low battery indicator, natch).

[lovablechevy] also included an AV out so she can connect her HandyNES to a larger CRT screen. Like our old Sega Nomad, this allows for a little two-player action – player one using the HandyNES and player two using an extra controller. Support for the Zapper was also included after modding the Zapper connection to a USB port.

Check out the video walkthrough after the break. To prove that her build isn’t a clone, [lovablechevy] also include a video of herself playing Battletoads past the point where the clones crash. Excellent work from the Queen of Bondo.

Converting a laptop computer into a desktop machine

[Michael Chen] found himself in possession of a thoroughly broken laptop. The hinges connecting the screen to the body of the computer were shot, and the battery was non-functional. After a bit of thinking he decided that it wouldn’t take much to resurrect the hardware by turning it into a desktop machine.

At the core of this hack is the hardware that you must keep for the computer to function. That is, the LCD screen, the motherboard, hard drive, and the AC/DC brick that powers it. [Michael] ditched everything else; the case, keyboard, trackpad, webcam, etc. Next he started building his own enclsure out of acrylic. First he sandwiched the LCD screen between a full sheet of acrylic and a bezel that was one inch wide on each side. Next, another full sheet was used to mount the motherboard and hard drive. You can see how the three sheets are connected by nuts and bolts in the image above. It looks like the only other alteration he made was to relocate the power button to a more convenient spot.

Once a USB keyboard and mouse are added he’s back up and running. We’ve got our eye on an old XP laptop that might end up seeing this conversion to become a dedicated shop computer. We just need to build in some more dust protection.

Creepy HDD activity lights just in time for Halloween

We almost skimmed right past this spooky HDD activity light thinking it was just another set of LEDs wired to the motherboard.  However, they explained right off that they didn’t want just another blinking light on their case. They wanted it to change its intensity smoothly based on hard drive activity. While there are a million ways this could have been over engineered, we think they did a pretty good job of simplifying the circuit. The bill of materials is pretty much just a handful of resistors, LEDs, an opto isolator, and a capacitor. The effect, is quite nice and can be seen in the video after the break.

Server not as think as you drunk it is

server-in-whiskey-bottle

[Janos] pulled off a unique case mod by fitting a computer system inside of a whiskey bottle. Inside you’ll find a 733MHz processor, 256MB of ram, a 40GB hard drive, and a 60 watt power supply. The specs seem a little light but since this mod is from 2006 we certainly understand. Using the right server software this will still keep up with today’s demands.

It sounds like the hardest part was putting holes in the bottle. After a few failed attempts, [Janos] found a professional glass grinder to cut the openings for him.

The whole thing was running a little hot and instead of filling the bottle with oil (oh, how we wish he had) he added a second fan in the bottle’s neck and drilled some air intake holes. This brought the temperature under control while preserving the boozy look of this creative enclosure.

Upgraded Atari 1024STf

atari-1024STf-case-mod

[Gerritt] wanted to give his crippled Atari 1024 STf a new purpose in life. He cracked it open and set to work filling it with some modern components. The keyboard from the nearly 25-year-old dinosaur doesn’t have all the keys we’re used to, nor did they all work, so he replaced the original with a 101 key model. The internal hardware was replaced with a microATX board, a picoPSU, Bluetooth and WiFi transceivers, a hard drive, and a slot-fed DVD drive. He even rebuilt the original mouse to use the circuitry from an optical mouse.

The final product is a 1.6GHz Pentium Mobile with one gig of ram. Now he has no need to pick up an EEE Keyboard PC when they hit the market.

High explosives PC case

ammo_casemod

[Ilias] let us know about his new HTPC case mod.  He took a surplus Ammo-case and with a bit of work turned it into a livingroom eye-sore masterpiece. His build has some nice touches, including a slot-fed DVD player, switch-based fan control, and key-and-button “nuclear launch” type power-on controls.

A few things to learn from this project: Cleanly cutting holes in a steel case for the connectors is tough.  You can see that [Ilias] did a pretty good job with it and in several cases used rubber gaskets to cover the rough edges. Secondly, the slot fed DVD had to be mounted upside-down.  We assume this will be fine, but we’d like to hear a follow-up after a few years of heavy use. Finally, the GFAF (girlfriend acceptance factor) ran very close to critical on this build as [Ilias] didn’t clean up the metal shavings on his porch and ended up with rust stains everywhere.

Case mods are an enjoyable hobby. We hope this will inspire you to take the leap.  If you do, don’t forget to send your completed project into our tip line.
