Bus Pirate Firmware Update V0g

June 25, 2009 by 10 Comments

buspiratefirmwarev0g

Firmware v0g for all Bus Pirate revisions is now available. Updates in this release include a bootloader, frequency generator/pulse-width modulator, SPI bus sniffer, MIDI library, configuration reports, improved user interface, and bug fixes. v0g is also the first firmware to fully support the v2 hardware branch.

We’re really proud of this release as it brings a much more consistent structure to the internal operation of the Bus Pirate. It lays the foundation for future CAN, LIN, and OBDII libraries, and it supports localization and translations.  Install and upgrade instructions are included with the firmware. Report bugs on the project issue tracker.

We document the new features after the break.

Wide Angle Lense Mod For The ATC2K

For those that have them, the ATC2K action camera is a decent little piece of equipment. It is waterproof and can save video for roughly 30 minutes on a flash card. The viewing angle of the lens leaves something to be desired though. This has been remedied in newer models. [raalst] shows us how to modify the ATC2K to install a new, wider angle lens, while retaining the waterproof seal.  He also takes us through a necessary mod to ensure clear video under water since the new lens was not initially intended for it.  Just in case you are curious, he’s using his for hobby radio controlled submarine dives.

Econo Monome

[Mike] really liked the thought of the Monome, especially the green aspect of their construction. He felt he could take it a step further. After 40 years of electronics tinkering, he had quite a spare parts box. He constructed his monome clone from stuff he just had laying around.  All of his pieces were either rejected samples from his company or outdated parts destined for the trash bin. Great job [Mike]. If you are planning to build one and don’t have the buttons laying around, you can get a more typical monome look and feel by going with the sparkfun RGB pads, like we did back in March.

Hackit: Boxee Now On Windows

June 24, 2009 by 27 Comments

Boxee, the free media center management and streaming application, is now available for Windows platforms. We’ve been following the developments of Boxee since we first announced its alpha this time last year. At that time, it was only available for OSX with promised Ubuntu support. We were a bit skeptical about the interface noting, “Unfortunately all the dynamic resizing, animated, sliding, floating info boxes make it behave like the zooming user interface’s retarded cousin”. Our interest in Boxee was almost entirely based on it being a fork of XBMC, the media center project developed for initially for hacked Xboxes. It was interesting to see Boxee become the interface of choice for hacked Apple TVs and then go mainstream with a big push at CES.

Have you been using Boxee as your media center? What do you love/hate? What about alternatives like XBMC, Plex, or MythTV?

EVIC Engine

The EVIC is a computer controlled internal combustion engine, utilizing a cam less solenoid actuated valve system. In addition to intake and exhaust valve control, the processor also handles ignition timing. With dynamic valve timing, it is possible to make an engine more efficient. Where a classic combustion engine would wastefully burn fuel, the EVIC can skip power cycles which are not needed. By increasing the valve duration, the CPU enables easy starting. The latest is the EVIC Mk3 which adds an exhaust valve sensor, and 3:1 solenoid leverage. There is a photo gallery with several EVIC engines. The Mk2 Twin is demonstrated in the video embedded below.

Wireless Arduino Cat Food Dispenser

catfooddispenser

Reader, [Andres Leon], has two adorable cats with very specific dietary needs. Instead of altering his schedule, he donned his hacking hat and designed a very solid cat food dispenser. The dispenser consists of a rotating drum with a slot in it and a PVC pipe Y-fitting to distribute the food evenly. The brains of the machine is an Arduino Deumillanove and an XBee module. The unit can be controlled by a web interface or it can run completely standalone. [Andres] ran into a problem where the drum’s resistance to turning varied based on how much food was inside. He solved this with a clever laser position indicator. A piece of plywood is lined up with the slot at the top so that whenever the slot is facing up it keeps the laser from shining on a photoresistor. The cats were afraid of the servo noise at first, but now they run to their bowls whenever they hear it.

Magic Lantern For Canon 5D

[Trammell] has released a new firmware for the Canon 5D Mark II DSLR geared toward film makers. The stock firmware was very limited on the audio side. This firmware adds features such as live VU meters, reduced audio noise, and crop marks for filming in different formats. The firmware is written in a manner that it can be extended fairly easily. Hopefully this will turn out to be as helpful as CHDK has been for point and shoot cameras.
