XBMC Hiding In An SNES Controller

March 23, 2010 by Mike Szczys 20 Comments

Here’s another SNES controller converted to house a USB system. The one we saw last time used a kit as an adapter for the controller but this version uses a home-built PCB and an ATmega8 microcontroller with the latest revision of an open source adapter for NES and SNES controllers. As you can see after the break, [Atarity] built the adapter, then added it along with a USB hub and thumb drive so that he could run a copy of XBMC from the controller. Now he’s got XBMC as a way to launch emulators for those classic games, as well as play traditional media.

You will be seeing more of this type of mod soon. We were tipped off that an in-depth tutorial for SNES controller hacking is on its way, although that is unrelated to [Atarity’s] work.

All Terrain Roomba

March 23, 2010 by Mike Szczys 16 Comments

This little rover gets around on rough terrain pretty well. [Dean Segovis] built it using parts from a Roomba. The Roomba uses wheels in conjunction with gearboxes that handle a lot of the dirty work in getting this prototype going. [Dean] grabbed four of them, as well as the motor controller board and batter, and installed them on this Rocker-bogie suspension. In the video after the break he mentions that this would be quite a good climber if the batter were relocated to the center of the body. An ultrasonic sensor adds obstacle avoidance with and Arduino taking care of the processing. We can’t wait to see future versions of the Roomba’s rough-and-tumble outdoor cousin.

PC Cooling Using 1000 Ft^2 Geothermal

March 22, 2010 by Mike Szczys 36 Comments

Are you still using heat sinks and fans to cool your computer? Lame. Tearing up your property to bury geothermal coils is definitely the way to go. [Romir] has been working on this for about a month and is just getting back data from the first multi-day tests. Take some time to dig through his original post. It includes something of a table-of-contents for the 35 updates he’s posted so far. Closed loop cooling seems to be trendy right now, we just didn’t expect to see a system this large as part of a personal project. The last one we looked at used just six meters of pipe.

Snega2usb Changes Name, Learns New Tricks

March 22, 2010 by Mike Szczys 18 Comments

[Matthias Hullin], the creator of the snega2usb let us know that its name has been changed to the Retrode. We watched this device go through the development cycle and learn to read SNES and Sega Genesis cartridges via a USB connection. Now it’s seeing some hacking to extend those capabilities. [Jon] managed to rig the Retrode up to read Virtual Boy cartridges. The Virtual Boy was a Nintendo console from the mid ’90s that used two different screens in a glasses format to produce a 3D gaming experience. Now that the cartridges can be easily dumped you have a chance to replay the titles using an emulator.

GPU Cooling To Fix RRoD

March 22, 2010 by Mike Szczys 64 Comments

[Rbz] fixed his friend’s Red Ring of Death stricken Xbox 360 by improving the GPU cooling. Because an overheating GPU is a common cause of the failure, he first tried to replace the thermal compound for better heat conductivity between the chip and the heat sink. This helped a bit but within two hours the problem was back. Troubled by the heat discoloration on the bottom of the DVD drive, he removed it and screwed a cooling fan to the GPU heat sink. That did the trick, so he moved the drive to the outside of the case with the aid of a longer SATA cable. It’s not pretty, but it worked.

Light Up Your Ride With An LED Mohawk

March 22, 2010 by Mike Szczys 21 Comments

[Garrett Birkel’s] weekly ride usually features some pretty wild costumes. He wanted something to step up his own look so he make this LED mohawk bike helmet. He had an LED strip to start with and found a way to use acrylic and clear plastic tubing to fold the lights into the appropriate shape. From there he designed a PCB for some DC-DC converters to provide regulated power. The juice comes from Lithium Iron-Phosphate cells, the same kind we saw in the electric bike assist battery a few days ago. We find it a bit wild that you can pick out the PWM of the LEDs in the lens effect of that photograph.

PIC Based USB Input Devices

March 21, 2010 by Mike Szczys 39 Comments

USB is convenient and that makes it desirable in many many projects. [Simon Inns] has the process down and is sharing it with his recent PIC based USB tutorial. Prompted by requests for help on the matter after having published a post about his Commodore 64 interface, he set out to detail the particulars when it comes to using the PIC 18F family as USB input devices. This example uses a PIC 18F4550 with the circuit built on a breadboard. There’s not much required here, an oscillator, a few passives, and a USB B connector. The magic really happens in the code. Take a look at this well-written guide and give it a try with your next project.

Don’t need USB? [Simon’s] game hack, the Ultimate Simon is always worth another look too.
