[Andrew] was getting some poor performance from a couple of USB devices he had connected through an unpowered hub. This is a problem because the hub prevents devices from negotiating with the host controller for more current. He fixed it by adding an external power supply to his USB hub.
In this case the PCB already had a footprint for a power connector. The manufacturer uses one board for several different models and just leaves the supply components unpopulated. [Andrew] managed to find a barrel jack in his parts bin that matched the footprint.
One important thing to do before hooking up the source is to disconnect the 5v wire from the incoming cable from the computer. The other tip we can give you is to use a good regulated 5v source to ensure you don’t damage the stuff you’re trying to power. That means avoiding deals that are too good to be true.
[Joe's] wife grew up playing Sega games and he wanted to help her unwind by reliving the experience. Since the work computer she uses when travelling isn’t a good place to install emulators he built this plug-and-play emulator inside of a Sega controller.
We’ve seen this type of thing a few times before (even with XBMC in a SNES controller) but there is one thing we hadn’t thought of lately. Newer versions of Windows have auto-launch disabled for USB drives. But [Joe] knew that there were still some USB sticks that manage to auto-launch anyway so he researched how those work. It turns out that they have two partitions, one is formatted as a CDFS which looks like a CD-ROM to Windows and allows auto-launch. He used this method of partitioning a USB stick, storing the ROMs on the mass storage partition and the emulator and the CDFS partition. To finish the hack he cracked open the controller and found room for a USB hub and the PCB from the thumb drive.
If you still have cartridges lying around you can pull the ROMs off of them over USB.
This is [Robert Jarvis'] new MIDI controller which he has christened the Archaeopteryx. It makes its home (quite nicely might we add) in a discarded wooden cutlery case. This provides a strong and stable base for the controls while keeping the electrical connections close at hand for any rewiring or repair work.
The interface is made up of several different input devices. The guts from two Korg Nanokontrols donated the sliders and pots. These are both USB devices and they join with a USB keyboard which has been rewired to work with the colorful push buttons. All three devices connect to a hub inside which makes the device work using just one cable connection to the computer.
There’s a lot of wiring shoved into that shallow case. But if he keeps the keyboard mapping straight we think it won’t be too hard to configure the device. We like it that [Robert] included a snapshot of the back-of-the-envelope prototyping plans he made. This kind of ‘how I got there’ information is what we’re looking for when choosing projects to feature.
[Niklas Roy] wanted to create electricity from moving water so he came up with this hyrdopower generator. It is part of his grand scheme to rent out small personal fountains made from buckets. They need electricity to run so he hooked up the generator to the water jet of a public fountain. It should be possible to use this setup with falling water in a similar way that other generators do.
To build the device he cut fins out of PVC pipe to use as the scoops. They are attached to a Shimano hub generator, meant for producing power while you pedal. The hub is mounted in the front for from a bicycle, which can then be mounted anywhere moving water is available. The only thing that worries us about the setup is [Niklas'] comment that being showered with water didn’t destroy the hub right away.
See the hub and the smaller fountains in the clip after the break.

[Gigawatts] built a pair of USB ports into his mouse and there’s enough room to plug-in small USB drives and dongles. After seeing Thursday’s storage mouse hack he decided to tip us off about the post.
He started with a Logitech G5 gaming mouse. The wireless version of this mouse has a battery pack, but on the corded version this space is used for a weight cartridge. Since he didn’t really care about that feature he ditched the weights, added a USB hub inside, and positioned the dual ports as seen in the photo. The void is deep enough for the mouse to function normally while hosting medium to small-sized devices. This is a fantastic solution that’s at least as impressive as Apple adding USB ports to a keyboard. We’d love to see it as a factory option.
Update: Video after the break

[Thice] wanted to try his hand at incorporating a USB driving into other devices. He chose to add storage to his USB mouse but didn’t want to alter the factory look provided by a color-changing LED inside. To make things fit he ended up cutting a good portion of a USB hub’s circuit board off and placing it beneath the mouse circuitry. You can see the board from the thumb drive wedged into one end of the case in the image above.
He sees this as a way of hiding data in plain sight. This is true, and it’s along the same lines we’ve seen before with a WiFi dongle in a mouse, or the thumbdrive in a controller hacks. To be truly hidden we’d like to see someone incorporate a microcontroller that monitors the mouse buttons for a certain code, and then toggles the voltage to the USB storage. This would simulate plugging and unplugging the drive, hiding it virtually as well as physically.
[Mr.X] added support for four controllers to his Super Nintendo (Google translated) by internalizing the multi-player adapter. In the video after the break you’ll notice that he also added some bling to the case by positioning the power LED beneath the logo and adding a two-digit display. There is a switch on the back that allows him to choose PAL or NTSC standards with the current setting shown on that display. While most people are going with emulators, [Mr.X] ended up with a custom piece of hardware with a clean finish.
