SNES Controller Modified To Be Completely Wireless

February 20, 2015 by Rick Osgood 9 Comments

[Pat] was looking for a way to wirelessly control his Fire TV unit. He could have just went with one of many possible consumer products, but he decided to take it a step further. He modified a unit to fit inside of an original SNES controller. All of the buttons are functional, and the controller even features a wireless charger.

[Pat] started out with a Bluetooth video game controller marketed more playing video games on tablets. The original controller looked sort of like an XBox controller in shape. [Pat] tore this controller open and managed to stuff the guts into an original SNES controller. He didn’t even have to remove the original SNES PCB. [Pat] mentions that it was rather tedious to rewire all of the buttons from the original controller, but in the end it wasn’t too difficult. The only externally visible modification to the original controller is a small hole that was made for a power button.

In order to make this unit completely wireless, [Pat] also installed a Qi wireless charging module. Now, placing the controller on a charging pad will charge up the small LiPo battery in just about 45 minutes. This controller would be the perfect addition to a RetroPi or other similar project. If you’re not into Bluetooth, you can try using a Logitech receiver instead. Continue reading “SNES Controller Modified To Be Completely Wireless” →

1.37″ CRT Restored By Hacklab For Miniature MAME Cabinet

December 13, 2014 by Matt Freund 27 Comments

For $5, [William] of Toronto’s Hacklab hackerspace got a hold of one of the smallest CRT screens ever made – about the size of a large coin. Over the course of a couple sessions – including a public hack boothside at their Mini Makerfaire – [William], [Igor], and several other members managed to connect it as a monitor directly off a Raspberry Pi. The end-goal is the world’s smallest MAME cabinet (smaller by almost half than this LCD one).

As Canada followed the US and stopped broadcasting analog back in 2011, it became quite a challenge to feed the screen a video source. They disclosed early that the easiest solution would just be an RF transmitter on the Pi and then tune the micro-set to that channel. Too easy. They wanted something elegant and challenging so they went digging into the circuitry to find a place to insert a composite video signal directly.

The real story here is their persistence at reverse engineering. The PCB was folded like a cardboard box to fit in the original case, making large portions of the circuitboard and wiring inaccessible. Even when they managed to trace the signal to what they thought was the appropriate chip (marked C80580), they could not find any information on the 30 year old chip. Noting that every other chip on the board was Panasonic and started with “AN5”, [Igor] suspected the mystery silicon was just renamed and went through every single datasheet he could find with that prefix. Combined with form factor, pin count and purpose, his sleuthing was rewarded with a guess for a match – the AN5715. His hunch was correct – using that datasheet led him to the answers they required.

Then they just had to figure out how get the composite signal the Pi outputted into something the chip would use to display the correct image. There were no shortage of challenges, failures and dead ends here either, but they had help from the rest of their membership.

Their project log is an interesting narrative through the process and in the end of course, it worked. It is displayed beautifully with a clear acrylic case and ready for a cabinet to be built.

Calculator + MSP430 + IR LED = TV Remote?

December 8, 2014 by Matt Freund 5 Comments

Eschewing the store-bought solution, [Stefan] managed to build a TV remote out of an old calculator. The brains of the calculator were discarded and replaced with an MSP430, leaving only the button matrix and enclosure. Rather than look it up, he successfully mapped the matrix manually before getting stumped with the infrared code timings. Some research pointed him to a peculiarity with Samsung IR codes and with help from an open source remote control library he got it working.

When the range was too limited to satisfy him he added a booster circuit and an LED driver which he snapped off the top of an old remote; now it works from 30 feet away. Some electrical tape and hot glue later and it all fit back into the original case.

It cannot take photos or play Super Smash Brothers, but it does what a remote needs to do: browses channels in the guide, control volume, and turn the TV on or off. Considering that all this calculator was built to do was boring basic arithmetic, it is a procrastination-enabling upgrade.

See the video after the break for some smiles.

Amazon Fire TV Update Bricks Hacked Devices

December 7, 2014 by Rick Osgood 60 Comments

The Amazon Fire TV is Amazon’s answer to all of the other streaming media devices on the market today. Amazon is reportedly selling these devices at cost, making very little off of the hardware sales. Instead, they are relying on the fact that most users will rent or purchase digital content on these boxes, and they can make more money in the long run this way. In fact, the device does not allow users to download content directly from the Google Play store, or even play media via USB disk. This makes it more likely that you will purchase content though Amazon’s own channels.

We’re hackers. We like to make things do what they were never intended to do. We like to add functionality. We want to customize, upgrade, and break our devices. It’s fun for us. It’s no surprise that hackers have been jail breaking these devices to see what else they are capable of. A side effect of these hacks is that content can be downloaded directly from Google Play. USB playback can also be enabled. This makes the device more useful to the consumer, but obviously is not in line with Amazon’s business strategy.

Amazon’s response to these hacks was to release a firmware update that will brick the device if it discovers that it has been rooted. It also will not allow a hacker to downgrade the firmware to an older version, since this would of course remove the root detection features.

This probably doesn’t come as a surprise to most of us. We’ve seen this type of thing for years with mobile phones. The iPhone has been locked to the Apple Store since the first generation, but the first iPhone was jailbroken just days after its initial release. Then there was the PlayStation 3 “downgrade” fiasco that resulted in hacks to restore the functionality. It seems that hackers and corporations are forever destined to disagree on who actually owns the hardware and what ownership really means. We’re locked in an epic game of cat and mouse, but usually the hackers seem to triumph in the end.

Homer Robot Ensures You Don’t Miss An Episode

October 14, 2014 by Rich Bremer 16 Comments

With our busy lives, who has time to pay attention to TV show schedules? [Tamberg] certainly didn’t and that is why he came up with the web-enabled TV remove he calls the Smart Homer. This miraculous device knows when ‘The Simpsons’ is being broadcast, turns on the TV and switches to the appropriate channel.

Like the real Homer, not too much is going on up in this toy’s noggin. A couple of IR emitters are mounted in place of pupils and the associated wires are run down into his body. Right between a pink donut and a Krusty burger resides an Arduino and ethernet shield. This electronic duo acts as a web server and looks out to the ‘net for an online script. The script polls an online TV Program Guide and if ‘The Simpsons’ are on at that time, it sends a signal back to the Arduino to turn the TV on.

Custom Video Streaming Box

October 12, 2014 by Bryan Cockfield 25 Comments

There are a lot of options out today for streaming video to your Internet-connected devices. Whether it’s Hulu, Netflix, Slingbox, or the late Aereo, there is no shortage of ways to get your TV fix. However, [Jaruzel] wasn’t happy with any of these services and wanted a more custom solution, so he built his own TV-streaming box out of hardware he had lying around.

[Jaruzel] gets TV from a service called SkyTV, but wanted to be able to stream it to his tablet, laptop, and XBMC. While rummaging through his parts bin, he came up with a WinTV tuner card for capturing TV and a Mini-ITX board to process everything and stream it out over his network.

Once the computer was put in a custom enclosure, [Jaruzel] got to work installing Puppy Linux. He wrote a boot script that configures the WinTV card and then starts VLC to handle the streaming service which allows him to view the TV stream over HTTP on the network. This is a great hack that would presumably work for any TV stream you can find, even if it’s just an over-the-air source.

Black Mirror, Black Hole: Kill Your Television

April 23, 2014 by Kristina Panos 15 Comments

don't waste your time TV screen Would you believe that some people think the internet is a time waster? Well, not at this particular address of course, but we can think of some other sites that are absolute rabbit holes without so much as a rousing game of croquet at the bottom. If you need help achieving what Tim Ferriss dubbed a Low Information Diet, there are browser extensions that will block your access to sites that keep you from getting things done. [Ivan’s girlfriend] has taken this time management tack seriously and even created a simple web page that states “Don’t Waste Your Time!” that will show if she tries to get to Facebook.

There’s one small problem with all this, and it’s been around for a long time. [Ivan’s girlfriend] still watches TV. Out of love and respect for her goals, he decided to prank her by blocking her TV viewing. In a delightful twist, the TV will display her own web page to her after 30 seconds.

They have digital and analog TVs, so he had to set up both in order to cover his bases. The digital TV is a monitor fed from a set-top box with HDMI out. As the STB can only be controlled via IR remote, [Ivan] used an HDMI switch to change from the STB input to a Raspi that will display the reprimanding web page and play Pink Floyd’s “Time“.

The analog TV took slightly more doing. He put a Raspi on the AV input, but connected it from the inside so nothing looked suspicious. The Raspi checks the TV status every second and switches to the Pi once the TV is on. Same deal: judgmental web page, Pink Floyd. The beauty part is that both of [Ivan]’s setups also record her reaction; the digital TV uses a dash camera and the analog uses an Android phone. Check out [Ivan]’s tour of the analog TV Pi after the break.

If you or [Ivan’s girlfriend] need even more time management help, there’s always the roll-your-own-Pomodoro timer.
