IPod Peripheral: ISee360i Hacking

[James] has done some work reverse engineering the protocols for the iSee360i peripheral. This iPod addon is a media player housing that features a 3.6″ screen. It can be used to play video on iPods that don’t otherwise have the capability because it just uses them as a hard drive. He picked up the device at a discount chain for $15 and wanted to load his own videos directly from Linux without using the Windows-based software that comes with it. There’s the gotcha; even if you encode a video exactly the same as the device’s example video, it will be deleted the next time you fire up the iSee.

After some trial and error [James] reverse engineered all of the quirky requirements to load video manually. There are strict, case sensitive file naming conventions, every file must have a perfectly formatted thumbnail image, and an index file entry must be made for the video. He’s done the hard work of hammering out the details, now it should be easy to write a Python script to automatically format and copy your pre-encoded videos for use.

MythNetVision To Cure Borked MythTV Hacks

Another group of developers has stepped up to the plate in the never-ending attempt to integrate online streaming video with MythTV. The new plugin is called MythNetVision and aims to bring streaming and downloading video functionality both easily and legally. That means without violating the terms of service of the providing website.

We’ve seen so many attempts that fell short it’s easy to be skeptical about the chances of this plugin actually working. Plugins like MythStream and MythVodka worked only temporarily before breaking and never seemed to provide a reliable option. Many people have tried adding Boxee, Hulu Desktop, or XBMC integration by launching these separate packages via the MythTV UI but that’s far from a clean solution.

It looks like MythNetVision is taking a slightly different approach. Although not yet available, the designers have built the plugin in two parts. The frontend is a fully skinnable user interface that parses RSS feeds to provide the hooks needed to browse, search, and view video. Depending on the content, a browser may be spawned to play the video, it may be played within MythTV’s normal player, or a separate download thread can be launch with video following after the appropriate buffer level is reached. The RSS feeds come either directly from the provider, such as the Revision3 feeds, or a scraper can be written to provide custom RSS feeds from sites that don’t have them.

We’ve seen a glimpse of the progress and we’re optimistic that we’ll see a reliable plugin. Early adoption and user script contribution are the best way to help ensure this so keep an eye out for the public release of this package.

360 Degree Video For Next-to-nothing

[Luis], a regular Hackaday reader, sent in some info about his 360 degree video experiments. He wanted a cheap device to use with a video camera, producing video that can be displayed using a free Flash software library.

The hardware consists of a mirrored light bulb, a square of glass, and some threaded rod. The camera lens attaches to the glass with the rod right in the middle. The lens will capture a donut image reflected in the mirror of the bulb. [Luis] then processes the result and uses Ryubin’s Flash Panorama to handle playback. He’s posted two clips as examples, the first of an “Existentialist Suburb Walker” and the second is some test footage while setting up for a shot. You can click-and-rotate the video while it’s playing to look around the area.

This could produce some great driving videos, without the need for multiple cameras. [Luis] does point out some problems with oscillation as the mirror on the end of a rod will amplify the effect of movement on the image.

Beauty In Destruction

This is not a hack. In fact it’s a promotional montage for a collection of scientific equipment that few of us could likely afford. But like yesterday’s giant marionettes over Berlin, sometimes even a costly and delicately-orchestrated achievement transcends its own not-a-hack-ness, fulfilling our brains’ lust for wonderment all the same.

Kurzzeit of Germany produces ballistics measurement equipment. The video depicts various combinations of projectiles and targets at up to one million frames per second, revealing unexpected beauty in hitherto unseen phenomena, and is the best damn ten minutes you will waste on the internet all day!

Sticky Light

With the availability of webcams and projectors, multitouch and interactive demos have become increasingly popular because they’re so easy. Students at the University of Tokyo took a new approach that uses lasers instead. They created Sticky Light, which uses mirrors, a laser, and a single photodetector. Unlike camera-tracking setups, this system requires no visual processing. The laser moves around and bumps into dark objects, sticking to them. It can follow drawings on the table or objects in space, such as shirt designs. They also created a few basic games and a demo that makes sounds based on the movement of the spots. Video of the project after the break.

Music Visualizer (oscilloscope)

The Music visualizer is actually a second build based on an earlier design[Thanks Roger]. The build was influenced by Zyra’s How to make an oscilloscope out of a television. The hack is quite simple, patch the output of an amplifier into the vertical deflection coils of the CRT. This is a good use for that old TV you may have laying around  but don’t want to recycle it just yet. While on the subject we had covered the Mac SE/30 audio visualizer in 2006. For those looking for something a little more hard core, here is a bit about Homemade cathode ray tubes.

Propeller-based Terminal

[Vince Briel] has created an embedded device based on the Parallax Propeller chip that acts as a serial terminal. It takes input from a standard PS/2 keyboard and outputs color VGA. It also has a second serial port to connect to a PC for debugging or programming. He is selling kits and has the schematics available. The board has a lot of hacking potential and it could easily be made into a video game or a Wikipedia browser.
