A very small HDMI display

replicape

With dozens of pocket-sized ARM boards with HDMI popping up, we’re surprised we haven’t seen this before. [Elias] made a custom driver board that takes an HDMI input and displays it on a very tiny, high-resolution display from a cell phone.

The display used is the same as what comes stock in the HTC desire HD. With a resolution of 800×480, it’s more than enough for a basic desktop, and while it’s not a 1080p monster from a few flagship phones, it’s more than enough for most uses.

[Elias]‘ board consists of a Himax display driver and a TI DVI receiver. Included on the board is an MSP430 microcontroller used for initializing the driver and display. This build was originally intended for the Replicape, a 3D printer driver board for the Beaglebone, but because the only connections to this board are HDMI and an SPI to the ‘430, this also works with the Raspberry Pi.

Automata and wooden gears

While most animated machines we deal with every day – everything from clocks to cars to computers – are made of metal, there is an art to creating automated objects out of wood. [Dug North] is a creator of such inventions, making automata out of wooden gears, cogs, and cams.

[Dug]‘s inventions are simple compared to turbine engines, but they still retain an artistry all their own. With just simple woodworking tools, he’s able to creating moving vignettes of everyday scenes, everything from a dog barking at a bird, to Santa Claus gracefully soaring over a house on Christmas Eve.

Below, you’ll find a video of [Dug]‘s creation, ‘An Unwelcome Dinner Guest’ – an automated dog barking at a wooden bird. There’s also a video of him being interviewed by the awesome people at Tested last year at the World Maker Faire.
