[Fall Deaf] built an Arduino based universal remote control system. It uses a shield which has both an IR receiver and transmitter. This gives it the tools to learn codes from your existing remotes and play them back in order to control the devices. This functionality is really nothing new, but we think the user interface he developed for the system is absolutely fantastic!

Software is web-based. You can simply point a remote at the Arduino and push a button. The receiver will store the code which can later be assigned to a virtual button. The image above shows the channel-up option being created; it will be added to the list once confirmed. From there any web enabled device – smart phone, tablet, netbook, etc – can be used as the remote for the system. The only feature we think is missing is the ability to alter the layout of the buttons, with larger areas for the most frequently used commands.

After the break you can see a demonstration of this system, as well as the one extra feature we haven’t touched on yet. [Fall Deaf] included a Piezo element in the hardware design which lets him knock on his coffee table to use the remote if a smart-device isn’t close at hand.

This is the Raspberry Pi board, an ARM based GNU-Linux computer. We’ve heard a little bit about it, but it recently garnered our attention when the machine was shown running XBMC at 1080p. That’s a lot of decoding to be done with the small package, and it’s taken care of at the hardware level.

Regular readers will know we’re fans of the XBMC project and have been looking for a small form factor that can be stuck on the back of a television. We had hoped it would be the BeagleBaord but that never really came to fruition. But this really looks like it has potential, and with a price tag of $35 (that’s for the larger 256MB RAM option) it’s a no-brainer.

Now there’s still a lot of rumors out there. We came across one thread that speculated the device will not decode video formats other than h.264 very well since it uses hardware decoding for that codec only. We’ll reserve judgement until there’s more reliable info. But you can dig through this forum thread where the XMBC dev who’s been working with the hardware is participating in the discussion.

Don’t forget to peek at the demo clip after the break too.

It happens to the best of designers, spending untold amounts of time designing a complex device just to find out that you missed a trace, or you couldn’t rout something to something else. As time marches on its becoming a bit less common to pop open a commercially produced device and see a little jumper wire or 2 flying across a pcb, or a resistor straddling an IC.

But when [Ilektron] opened up a Yamaha Dolby Pro Logic receiver to scavenge for parts he saw a very big “oops” and a even wilder fix. The maker took a pair of relays, flipped them “belly up” and hot glued them into place on top of a pair of ICs. Then the mess was “dead bug” wired to the circuit using insulated and uninsulated bus wire, contacts were then reinforced / insulated using more hot glue.

This is one of the most hacky fix we have seen in a commercially produced product, but we would love to hear your amusing horror stories of “WTH did they do?” So join us in the comments after the break.

This isn’t an airplane, it’s a simulator. But you won’t find it at a flight school as this labor of love is a home build of a 737 cockpit (translated) that has been going on for more than two years.

It started off as a couple of automotive bucket seats in a room with two computer monitors to display the view out the windscreen. From there each piece has been meticulously added for a wonderful overall reproduction. The range of skills needed to pull this off is impressive. The seats have been rebuilt with padding and upholstery true to the Boeing factory options. The support structure that forms the domed front of the aircraft was built from wood with a metal bracket system to hold the overhead control panels in the right position. The only thing missing here is the rest of the plane. Take a look at the simulated landing run in the video after the break to see what this thing can do.

Looking for something that will take you for a bit more of a ride? Here’s a collection of motion simulators that might satisfy your craving.

We’re guessing that if you ever though of buying an arcade cabinet it was only briefly, and you decided against based on the difficulties of moving and finding a place for such a large and heavy item. You could go the opposite way and build a controller for a  MAME box, but for some, there’s no replacement for the real hardware. This Christmas gift is the best of both worlds, a JAMMA box which uses traditional hardware in a more compact cabinet.

[Majtolycus'] boy friend is a sucker for a game of Battle Balls. She looked around for an original logic board and after several weeks of searching had to settle for the Japanese version of the game called Senkyu. To patch into the board she also picked up a JAMMA harness, power supply, RGB to VGA video converter, speaker, and some Happ arcade controls. The whole thing goes into a wood box which connects to a VGA monitor (or the VGA port on your HDTV).

The system is easier to store than a full-sized cabinet, and if a deal comes along, you can buy additional JAMMA logic boards to play.

[Thanks Adam]

[Entropia] is just putting the final touches on his bar-top MAME cabinet (translated). The project started out as a 3D model to get the case dimensions just right. An old laptop is being, so the enclosure was designed to fit the bare LCD assembly and hide the rest of the computer. [Entropia] had access to a CNC mill through an education program and used it to cut most of the parts for the case out of MDF.

From there the build proceeds as normal. Mounting holes for the controls were cut with a drill and hole saws. We think it’s a bit easier to lay this design out once you have the control panel itself milled, rather than try to get it right in the 3D model. The image above is part way through the build. Since it was taken the case has been painted and a sound system was added but it looks like it’s still waiting for a bezel over the LCD and a marquee for the masthead.

You can see a demo of the game selection UI after the break.

[Garrett Mace] decided to beef up his 58 inches of plasma with 60 Watts of LED lighting. After seeing a ton of Ambilight clones using his LED modules, he’s built his own powerful system. Not surprisingly, it’s nothing short of professional-grade work.

Kudos to [Garrett] for showing the entire process in the video after the break. We’re talking about his planning stages, which are so often left out of build logs. He first measures the back of the television, and does some testing for distance and angle of the Satellite LED modules to establish how many should be used and to estimate the optimal spacing. From there he modelled a framing system before getting down to the actual build.

The wood frame is made up of a box with a horizontal crossbar serving as a place to mount the drivers. Around the edges, tilting rails were added to make the angle of the LED modules adjustable. As with many other Ambilight clones, [Garrett] uses the boblight software to drive his system and we appreciate it that he included his configuration file for reference. Once up and running the effect is breathtaking (and possibly blinding).

Legalities of doing something like this aside, this concept by [MadSci labs] gives some insight into how one would go about recording a 3D movie in 3D.  Probably many of you have wondered if this could be done, but they took it one step further and actually made a device capable of doing just that.

[MadSci labs] solution involved taking some 3D glasses home from a theater, cutting them to size, and taping them to a HTC EVO 3D phone.  Each lens piece was taped over a different camera lens to separate out the two 3D elements needed to produce a stereoscopic image. Their experiment was successful, however some loss of quality was experienced.  Because of this, we’re not expecting to see a lot of in-theater movies pirated this way, but given a more professional-quality build, you never know what will happen.

You can see the “results” of their experiment after the break. As it’s not in 3D, it should give you an idea of what is going on. Read the rest of this entry »
