Reader [deren lik] pointed out the world of direct to garment printing to us. You can purchase commercial machines that will print directly onto a t-shirt using inkjet technology. Unfortunately, these machines cost ~$10K, so hackers have decided to fill in the gaps. DIYDTG hosts plans for how to build your own DTG printer. Their standard instructions are based around the Epson C88 printer. A custom carrier is constructed and then the printer components are bolted on top. Commercial DTG printers are also based on Epson parts and you can easily purchase the garment inks even if you didn’t pay a premium for your printer.

60 Watt Solar Panel Built From Cells

September 14, 2008 by Jason Rollette 19 Comments

Our love for solar projects continues on with this method to make your own solar panels. [Mike] built a 60 watt solar panel from individual solar cells he purchased off eBay. Procuring parts off of eBay normally causes others hardship when they try to duplicate the project, however in this case there are so many types of cells people can use to produce their own unique solar panel. Even cells that are extremely damaged my still be used, as in this example. To charge a 12 volt battery the number of cells in series just needs to be 16-18 volts, and the rest in parallel will supply more current. Charging a battery without a charge controller is not recommended, but commercial ones are easily had. Those not interested in jumping all the way in with solar may want to test the waters by building their own panel and putting it to use as a charging station for your portable gadgets.

Cheap USB LCD

September 13, 2008 by Eliot 13 Comments

Part of the pre-Vista hype was the idea of auxiliary displays. Laptop and desktop displays would provide additional information from your computer. The Vista SideShow feature hasn’t really caught on and the surplus hardware has started to drop in price. Take this PicoLCD for example: It’s a 4×20 character LCD with an IR receiver, multiple buttons, and a USB connection. The best part is: it has Linux drivers and an open source SDK. We know a lot of you like wiring up HD44780 based screens, but it’s hard to pass up a $50 prepackaged solution with such nice extras.

Playstation 3 Boomerang Controller

September 12, 2008 by Eliot 11 Comments

Reader [HotDog-Cart] is an active member of the benheck forums and recently completed this Playstation 3 boomerang controller. The boomerang was originally shown with the Playstation 3 prototype and was severely panned by the press. [Josh] started with a cheap 3rd party controller that was approximately boomerang shaped. He enlarged the controller body ~20% using bondo. The internals were replaced with gear from an official Sony controller. It was finished with a coat of black paint. It’s definitely a nice build and the new internals mean it probably feels as good as any factory controller.

On the seventh anniversary of the events of September 11, 2001, it’s important to reflect on patriotism, nationalism, and responsibility to your country and motherland. This USB memorial lets us think about our contributions to our great nation. Or it’s just a tribute to misguided nationalism and capitalism via insipid flag waving. Instructions are available at Instructables.

Interactive Globe Display

September 2, 2008 by Caleb Kraft 1 Comment

[ERASME] built this interactive globe interface for an exhibit on Inuit people and their land. The goal was to have a tactile input device to Google Earth data. The unit is composed of a half globe for location selection, a touch pad for layer selection, and a Wiimote for view changes.They had to develop their own driving application for Google Earth as none exists for Linux. The software, called KeyEvents takes inputs from all the devices and mimics keyboard and mouse control in Google Earth.

There is much more information on how they got the pieces to work together, as well as some videos in french showing the device working. One thing that stands out though is that they decided to use direct association on their Wiimote, thus stopping rogue Wiimotes from gaining control. Who would carry a Wiimote around just to hijack public displays? We would.

Modular Portable System

Reader [John Grayson], known for his multiconsole portable, has constructed a brand new portable. Not liking the controls or the tethered nature of retro TV games he decided to build a modular portable system. He built a custom system that uses cartridges created from TV game systems. The device has a 5.4″ screen and two Canon batteries for 4.5 hours of play.
