When the original Microsoft Xbox was released in 2001, one of the most notable features of its design was that it used a number of off-the-shelf computer components. Inside contemporary offerings from Nintendo and Sony you’ll see almost nothing but proprietary components, whereas cracking open the Xbox reveals an IDE hard drive, a customized PC DVD-ROM drive, and an Intel Pentium III CPU. Depending on which team you were on, the Xbox’s close relation to PC hardware of the day was either a point of honor or ridicule in the early 2000’s console wars; but regardless of politics, it ended up being instrumental in all of the hacks and mods the console got over its lifetime.
In that light, [P8ntBal1551] managing to jam a modern computer into the shell of an Xbox is like having the last laugh in this nearly two-decade-old debate. Wanting to build an HTPC that wouldn’t look out of place in his entertainment center, he figured the Xbox would make a suitable home for his Intel 4460 powered build. Not to say it was easy: getting all of the hardware and associated wiring inside the case took a bit of cheating, but the end result looks good enough that we’ll give him a pass.
The key to this project is the 3D printed structure inside the Xbox’s case that holds everything together. Painstakingly designed to align all of his components and cooling fans, it took over 58 hours to print just the base plate alone on his CR-10.
Even with all of his primary components installed, [P8ntBal1551] still had to wrestle with an absolute rat’s nest of wiring. He couldn’t find smaller versions of a number of the cables he needed, so he had to resort to some creative wire management to get everything packed in there. In the end, there was simply too much gear for the Xbox’s case to legitimately fit, so he ended up printing a spacer to fit between the bottom and top halves. Though in the end even this worked out in his favor, as it gave him a place to mount the integrated FLIRC IR receiver without having to cut a hole in the original front panel. The end product looks close enough to stock to be almost unnoticeable to the casual observer.
Its been a while since we’ve seen a hack for Microsoft’s original black and green monster, most of the Xbox projects we see are in relation to its significantly more popular successor. It’s always nice to see people keeping the classics alive in their own way.
Shards of silicon these days, they’re systematically taking what used to be rather complicated and making it dead simple in terms of both hardware and software. Take, for instance, this IR to HID Keyboard module. Plug it into a USB port, point your remote control at it, and you’re sending keyboard commands from across the room.
To do this cheaply and with a small footprint used to be the territory of bit-banging software hacks like V-USB, but recently the low-cost lines of microcontrollers that are anything but low-end have started speaking USB in hardware. It’s a brave new world.
In this case we’re talking about the PIC18F25J50 which is going to ring in at around three bucks in single quantity. The other silicon invited to the party is an IR receiver (which demodulates the 38 kHz carrier signal used by most IR remotes) with a regulator and four passives to round out the circuit. the board is completely single-sided with one jumper (although the IR receiver is through-hole so you don’t quite get out of it without drilling). All of this is squeezed into a space small enough to be covered by a single key cap — a nice touch to finish off the project.
[Suraj] built this as a FLIRC clone — a way to control your home-built HTPC from the sofa. Although we’re still rocking our own HTPC, it hasn’t been used as a front-end for many years. This project caught our attention for a different reason. We want to lay down a challenge for anyone who is attending SuperCon (or not attending and just want to show off their chops).
This is nearly the same chip as you’ll find on the SuperCon badge. That one is a PIC18LF25K50, and the board already has an IR receiver on it. Bring your PIC programmer and port this code from MikroC over to MPLAB X for the sibling that’s on the badge and you’ll get the hacking cred you’ve long deserved.

If you’ve built yourself a home theater PC, one of your highest priorities is probably coming up with a convenient control solution. The easiest way to do this is to simply use something like a wireless keyboard and mouse. But, that’s not very conducive to an enjoyable home theater experience, and it feels pretty clunky. However, if you’ve got the right components lying around, [Sebastian Goscik] has instructions and an Arduino sketch that will let you control your HTPC with any IR remote control.
There are a number of ways you could control your HTPC, and we’ve featured more than one build specifically for controlling XBMC over the years. Unfortunately, most of those methods require that you spend your hard earned money (which is better spent on popcorn). [Sebastian’s] setup can be replicated with things you probably have on hand: an Arduino, an IR remote, and a scavenged IR receiver. The IR receiver can be found in many devices, like old stereos or TVs that themselves were controlled via an IR remote.
It starts with an Arduino Sketch that lets you can see on the serial monitor what code is being generated by the button presses on your remote. These are then scripted to perform any task or function you like when those buttons are pushed. The most obvious use here is simple directional control for selecting your movies, but much more complex tasks are possible. Maybe someone can program a T9 script to type using the number buttons on most remotes?
If you’re hungry for a portable HTPC (Home Theatre PC) solution, maybe packing everything into a stylish mini lunch box is the way to go. [tomhung] wanted a quick and easy way to drag his media around while he’s away from home, but in an intentionally portable, self-contained enclosure, and the Star Wars lunch box provided plenty of space for the necessary guts.
Inside, he’s stacked the RasPi and a USB hub on top of one another. Each is mounted to its own platform made out of plastic DVD covers, and kept separate by standoffs carved from what appear to be the casings of inexpensive plastic pens. The stack also includes a 250GB 2.5″ HD, which [tomhung] simply attached with velcro for easy removal. The cables underwent minor surgery to keep the rat’s nest under control, and although the interior may still cause cable management enthusiasts to cringe, the exterior of the box cleans up well for its evening out. [tomhung] fit a simple 6-port keystone wall plate to the face of the lunch box to provide simple connections for all the important plugs.
[Benoit Frigon]’s builds are a tribute to tidiness: both his HTPC and media server are elegant creations packed full of features. He has quite the knack for clean builds in this form factor; his PBX server was met with high praise earlier this summer.
For the HTPC, [Benoit] gutted and cleaned an old DVR case and modified it to house a Mini-ITX board. He added standoff mounts to support the motherboard, then sketched up a template for the IO shield as a guide for cutting the back panel. The front of the DVR case originally had a 4-digit 7-segment display and a few simple buttons. Though he kept the original button layout, [Benoit] chose to replace the segment displays with a 20×2 character LCD. The new display is controlled via a python script on the HTPC, which runs an OpenElec Linux distro with XBMC 12.0.
The HTPC’s hard drive bay is a bit lighter these days, because [Benoit] decided to migrate his media storage to a separate server. Inside the new home media server is yet another Mini-ITX motherboard with an embedded Atom N2800 that runs Ubuntu Server. Live television streams via a WinTV HVR-2550 TV tuner and TVHeadend software. The case originally suspended the tuner from the IO bracket on the back (and nowhere else), which left the rest of the card dangerously unsupported inside. [Benoit] solved the problem by building an additional aluminum bracket that firmly holds both the PCIe riser and the tuner. Check out both builds’ pages for downloadable templates, software details and bill of materials.
This sexy beast is [DeFex’s] new silent home theater PC. To give you an idea of scale, that motherboard is a Mini ITX form factor. Mounted below it is the solid state drive which is an SLC version chosen because they tend to last longer than the MLC variety. This distinction comes with a price tag that is $100 more expensive.
But we digress. It’s the custom case that really caught our eye with this build. The frame is made of a huge aluminum heat sink. It measures about 7″ by 10″ and sets the final foot print for the computer. An aluminum puck was added to transmit heat from the processor to the heat sink. Holes were drilled and tapped into the heat sink to accept the brass stand offs which hold the motherboard in place.
The near side of the case is a sheet of acrylic. It connects to the rest of the case using 3D printed brackets at each corner. There is an additional bracket on the bottom to hold the hard drive in place. The sides of the case are filled in with bicycle spokes which also find a home in the corner brackets. Now the hard part will be figuring out which orientation looks the best for displaying his fine craftsmanship.
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.
