Plex Hack Runs Apple TV Without A Jailbreak

June 5, 2013 by Mike Szczys 28 Comments

Apple has been keeping a tight leash on the third generation of their Apple TV hardware. Not only has it stood up to every attempt at a Jailbreak, but they don’t allow 3rd party applications through the app store like the other iOS hardware does. The second generation hardware was a popular platform for XBMC. It required a jailbreak to load the home media software which is why it can’t be done on the newest box. But here’s an alternative. This hack uses DNS redirects to make Apple TV 3 a Plex frontend.

Instead of putting new software on the Apple TV this uses a separate computer to intercept its web traffic. You aim your Apple TV DNS at the computer running the script, then use the native Movie Trailer app, which will be populated with movies and TV shows from your Plex backend. All other functionality will be retained, making for a near-perfect solution. For more info on the system check out this forum.

Ambilight Clone Has Meaningful Amount Of Resolution

May 29, 2013 by Mike Szczys 37 Comments

We don’t have an Ambilight clone on our own home theater, but seeing this one in action makes us wonder if we shouldn’t add it to the ever-growing list of projects we need to tackle (right below that POV display we’ve been putting off for years). [Falldeaf] built the colored light augmentation system using a set of WS2801 controlled LED pixels. There are a lot of them, and this results in the ‘meaningful resolution’ we mentioned in the title. The image on the screen is the opening to a James Bond film. You’ll remember that the camera shot down a rifle barrel follows him as he walks across the screen. There’s enough LEDs here to have to the light follow him across the screen as well. This is a nice touch that we don’t see in every Ambilight clone project.

A frame of fake-wood angle bracket holds each LED pixel in place. The entire assembly attaches to the VESA mounting holes on the back of the television. An Arduino addresses the lights while the Boblight package processes the video to acquire the lighting instructions. We think the hue is a bit off, but otherwise it’s a solid offering.

We’re still hoping the Microsoft IllumiRoom becomes a thing.

Raspberry Pi Housed Inside A Computer Monitor

May 9, 2013 by Mike Szczys 22 Comments

rpi-inside-a-computer-monitor

Behold, something we’ve always wanted. [Matthieu] mounted his Raspberry Pi board inside of a computer monitor. His work makes for the cheapest smart-TV modification we can possibly think of.

The image above shows the monitor’s driver board on the left, with the Raspberry Pi mounted on the back plastic cover. [Matthieu] used a short HDMI cable to connect the two. The HDMI connector plugs into the RPi directly. The other end has been cut off and the wires soldered to the DVI pins on the monitor’s PCB. This is not a problem since HDMI and DVI use electrically identical protocols. The one thing missing is audio. But if you were pulling off the same hack with a device that had HDMI (like a television) it would just be a matter of also soldering in the audio connections. While he had his iron hot he also connected a 5V source from the monitor board to the RPi. He completes his hack by cutting a slot in the monitor case to allow access to the SD card.

We’ve long wanted an XBMC computer we could velcro to the back of the TV and the RPi turned out to be just the thing. Now we’ve got to consider cracking open the TV to replicate this internalization hack!

Chromebook Hack Controls Your Television

[Michael Kohn] only accomplished about half of what he set out to, but we still think his TV channel switcher from a Chromebook turned out nicely. When starting the project he wanted to include a grid of listing so that he could choose a specific program, but decided that scraping the data was too much work for this go-round.

The Chromebook doesn’t include an IR transmitter so he built one using an MSP430 chip. He had previously built a little transmitter around an AVR chip and was surprised to find that the internal oscillator on that was quite a bit more accurate than on the MSP430. Timing is everything with the Manchester encoded signals used for IR remote controls so he used his oscilloscope to tune the DCO as accurately as possible.

The app shown on the screen was written in Javascript. Google published some example code on using RS232 with the computer; [Michael] used this resource to provide communications between the computer and the microcontroller.

Original Hardware For Fifteen Consoles Jammed Into Recently Completed Project Unity

This boxy monstrosity is big for a reason. It lets you play games on the original hardware of fifteen different gaming consoles. That’s right, we said original hardware. One of the main goals of Project Unity was to keep the stock equipment by making any type of emulation — hardware or otherwise — taboo. The size of the case is a function of how much stuff is actually crammed in there. But the final shape was dictated by the available opening in [Bacteria’s] living room entertainment center.

The video after the break walks us through each aspect of the build. We’re floored by the quote of 3,500 hours of build time. But as you get a look at the wiring-hell of each different module it’s easy to understand why it didn’t just build itself. One power supply and one controller make for the least complicated user experience possible. We already looked at a giant switching mechanism that selects one console at a time and the singular controller unit. But [Bacteria] has a lot of other tricks up his sleeve which make this gold mine of a hacking reference piece.

Ikea Dioder Ambilight Hack

March 28, 2013 by Ryan Fitzpatrick 8 Comments

There are a lot of hacks out there for Ikea’s Dioder LED light set. [Lambertus] wanted to create an easy and affordable ambilight while keeping the hardware modifications to a minimum. He also wanted anyone to be able to easily duplicate his work. He recently wrote in to share his successful solution.

The customizations boil down to three main steps: solder the ICSP connector wires to the test points on the Dioder PCB, connect a PIC programmer to the ICSP port (and reprogram), and attach a 5V RS-232 device to the ICSP port. The software was the most difficult part of the procedure for [Lambertus]. The PIC16F684 didn’t contain the required UART and PWM controllers, so he had to get crafty. Fortunately he’s done all the work for us, and lists the necessary .hex file he created on his site.

By adding support to boblight, his new ambilight is working with his media center very nicely. There’s a little demo video after the break.

Epson Projector LED Mod

March 28, 2013 by Ryan Fitzpatrick 46 Comments

Projector bulbs can be incredibly expensive to replace. Sometimes it’s more cost efficient to just buy a whole new projector instead of a new bulb. [Shawn] recently found a nice deal on an ‘as is’ Epson EMP-S4 on eBay and decided to take a chance. He assumed it probably worked with the exception of the missing lamp the seller mentioned. His suspicions were correct, and one custom LED mod later, his projector was up and rolling.

Without a stock lamp installed, the projector would give an error message and shut itself off. So, the first step was to wire up a little bypass. Once that was taken care of, [Shawn] installed a 30W 2000 lumen LED and custom fit an old Pentium CPU heatsink to keep the LEDs temperature down. He also wired up the heatsink fan in parallel with the stock exhaust fan for good measure. Optical lenses help focus the light, and some custom wiring makes the LED turn on and off just like the stock lamp would.

In the end, his first experiment was a success, but [Shawn] wants to try an 8000 lumen 100W LED to make it about as bright as the stock lamp was. Check out a little video walkthrough after the break.

[Thanks Shawn]
