Hackaday Links: Sunday, April 7th, 2013


Let’s wind down the weekend with some projects that didn’t quite warrant their own feature, but we think they’re still worth a look.

First up is a quick tip on cracking the lids on those hard to open jars of food. [Jason] says just grab about a foot of duct tape and the lid will come flying off. And while you’re searching for that roll of tape why not grab some foil tape to build a cooking oven. [Gabriel] built this solar oven by covering curved wedges of cardboard with foil tape and combining them to form a parabolic reflector.

Next we’ve got a trio of hacks that will come in useful in your home shop or at the local Hackerspace. Organization is key, and here’s a resistor storage system that uses #6 envelopes [via Reddit]. Also useful is the tip from [Felix] about using a tile saw to get clean cuts on your circuit boards. And if you’ve ever been plagued by a laser cutter job that doesn’t fully sever the material [Dan] wrote a guide on using a fence so that you can reposition the piece for another run.

Finally, we’re hoping we weren’t the only ones that didn’t realize the Raspberry Pi has an unpopulated footprint for a reset button. Now we’ve got to figure out if it’s okay to leave the PSU plugged in (based on it’s current consumption while the RPi is in power down) and hack together some sort of TV-based reset circuit for our RPi XBMC setup.

Building a touchscreen XBMC setup with the Raspberry Pi


[Andrei Istodorescu] has been hard at work building a 7″ touch-screen rig which runs XBMC. It may be upside-down, but the Raspberry Pi board which is front and center is still easily recognizable. There’s a lot of stuff connected to it in order to pull this off, and even more software configuration. But as you can see in the clip after the break he did get it working!

The screen is an eGalaxy 7″ touch sensitive module he picked up on eBay. It sounds like it was meant for a backup camera in the dashboard of a car. He compiled his own Linux kernel to add support for the screen. It uses HDMI for the video interface with the driver board, and the touchscreen connects to one of the USB ports. The rest of the setup involves compiling XBMC with touchscreen support and calibrating the screen to accurately sense input.

XBMC workaround for Android hardware video acceleration


An unofficial, but fully functional release of XBMC should make the uber-popular media center software work with almost all Android devices. About six months ago the developers of XBMC announced that it had been ported for Android. That was true, but there was one caveat. The port was made functional on one specific Android device. The hardware company Pivos paid for the devs to add support for their Xios DS device. Although that build could be run on other Android devices, the hardware video acceleration could only be use if it was the same as the Xios. When not using the hardware acceleration many common video formats would only play at a few frames per second, if at all.

This build is a workaround and is not officially supported. What it brings to the table is the ability to use an external media player with XBMC. This way any video format which your Android device is capable of playing (with hardware acceleration) can be launched from XBMC but will be played by the native video application. We haven’t tried it for ourselves. If you have we’d love to hear about your experience in the comments.

ODROID-U2 is latest barebones board begging to be used


Oh hey, another barebones dev board. Well, that’s what we said to ourselves when we first saw this picture, but the way this is presented is like crack for geeks. It starts with this tiny board, which has a footprint smaller than a credit card. But once you start looking at the add-ons you’ll want to watch out or you’ll cover yourself in drool.

The name of the game here is speed. It’s running a quad-core Cortex-A9 chip with a Mali-400 graphics accelerator. There is no on-board storage, but the microSD slot is meant to be used for OS and storage. A faster option is to use a NAND add-on board offered in 8, 16, and 64 gig capacities ($25-$79). There is a micro type-D HDMI connector and the device is powered by a cellphone charger. It ships with a big heat sink that acts as a case for the board.

After the break you can see it booting Android and immediately loading into XBMC. The menu looks mighty snappy, making us think this is a great alternative to using Raspberry Pi as a media center. But you’ll pay for the faster speed and ability to run Android. The rig they’re showing off, plus the add-ons, comes out to about $132. There are also questions to be answered as to which video formats are supported through hardware decoding.

Raspberry Pi reaches critical mass as XBMC hardware

For years I’ve been dreaming of a streaming media device that could just be stuck to the back of a television. Since XBMC has been far and away my favorite set-top box software, I’ve closely monitored hardware developments that can run that package. Now I think it’s time to declare that the Raspberry Pi has achieved the base specifications to be branded the XBMC device that rules them all.

There are a huge range of opinions on this topic, but please hear me out after the break to see what has brought me to this conclusion.

One remote to stream them all

We’d bet that most readers stream video as the lion’s share of their entertainment consumption. It’s getting easier and easier thanks to great platforms like XBMC, but not everything is available in one place, which can be a bit off-putting. [Tony Hoang] is trying to simplify his viewing experience by creating one remote to rule all of his streaming software. He’s got an HTPC connected to his entertainment center, and used a bit of scripting to add some functionality to this Lenovo N9502 remote control.

The hack is entirely software-side. The remote already works quite well, but he remapped the home, end, and page up buttons, as well as the mouse controller. The three buttons will launch XBMC, Hulu, and Netflix respectively. They are also set to kill the other applications before launch so that one button will do everything needed to switch between one another. The mouse remapping takes care of up, down, left, and right keys for navigation in the UI and control of the playing videos. See a demo of the setup after the break.

Everything was done with autohotkey scripts for Windows. But this should be easy to code with other OSes as well. If you’re prone to have a slip of the finger you might want to work out a double-click to launch the applications so you don’t accidentally hit a key in the middle of your favorite show.

XBMC hits Android

XBMC just issued the announcement we’ve been waiting to hear for some time now. The Android platform is now officially supported. Having seen the popularity of this open source media center software, and the willingness of some to spend hundreds of dollars on small computers to use it as their set-top-box interface of choice, we knew it was only a matter of time before a hardware manufacturer stepped up to the plate. In this case it is a company called Pivos Technology Group, who helped fund the push to bring XBMC to Android.

The good news is that the Android version of XBMC should work on a very wide range of devices. The bad news is that it will take a bit of time for that wide range of devices to support hardware video acceleration. Right now the only platform that has the hardware accelration for all video formats is the Pivos XIOS DS unit seen above. Looks a bit like a white version of the Apple TV huh? This turns out to be a great alternative to the Apple hardware, which requires a jailbreak to run XBMC and there is no jailbreak available for the current generation of that hardware. You can grab the XIOS DS for about $100-120, and as you can see after the break, it runs XBMC without a hitch, shows the ability to navigate menus while 1080p video is playing, and demonstrates working video plug-ins.

Plus, it’s an Android device with access to apps like any other. We looked around and it seems the Netflix app will work, but there is currently a problem with the video driver on units which have been upgraded to ICS. You can check out an unboxing of the device in this forum post, which is where we got the image seen above.
