Here’s a pretty simple hack to enable playback from a USB drive on LG televisions. It only works on European hardware, the LH, LF, and some LU models. The hack consists of downgrading the firmware to version 3.15, then navigating through some service menus.
It’s not quite as hardcore as the Samsung firmware hacking, but the added functionality is really great.
[Rogal] wrote a cell phone application called ToneTool that generates audio tone sequences. It can be used to output DTMF and SelCall sequences which are used by telephone systems and radio-telecommunication hardware. The software is written in J2ME so if you have a cell phone that can run Java apps it will probably work for you. This is like a digital-age Blue-box in everyone’s pocket. But we don’t think there’s too much opportunity for the mayhem seen with the original phone phreaking.
See him generating and sending DTMF commands over an Echolink network in the video after the break.

It seems a bit late to the party, but Microchip has just announced a family of PIC development boards for Apple products. The three offerings include a digital audio development kit, 8-bit accessory development and charging kit, and a 16-bit accessory development and charging kit for iPhone or iPod.
We’ve seen a lot of homebrew Apple addons that use microcontrollers. This not only takes the hardware interface to the next level, it does it with Apple’s blessing. But somehow that doesn’t seem like quite as much fun.
Being hackers, sometimes we just want to hack something together, not engineer it. This projector is a great example. Made mostly out of cardboard and duct tape (or duck tape if you prefer). He picked up a 12v LED array, a cheap fresnel lens, an LCD from a “back up monitor” and a focusing lens taken from a magnifying glass. Sure, we’ve seen better, much better. But seeing an evenings worth of feverish wire twisting and taping is always pleasant. It may look pretty dim in the video, it may be as well, but keep in mind that it is common for them to appear much brighter in person or if shot with a night setting on a digital camera.
The LED display toy known as the Peggy2.0 just keeps getting cooler and cooler. [Leonard] is now sharing with us how we can stream flash animations to one. It requires some Java and an Arduino, but the final effect is quite fluid and responsive. We’ve seen the Peggy grow from basically an electronic litebright to doing video and even being chained together to make larger displays.
