Hacking the EZ430 Chronos Watch on the Mac

Today my TI EZ430 Chronos Watch arrived, and I spent a little bit of time hacking it on my MacBook Air. It turns out that even though the documentation seems to require either a Windows machine or a Linux box, you can communicate with the watch from the Mac by modifying the serial port information in the TCL source.

How to get Maplin's USB Microscope working on a Mac

I just brought Maplin's USB Digital Microsoft with 400x magnification, which is advertised as having Windows-only drivers. System Profiler identified the chipset as being from Vimicro Corporation. I went to the Driver Download section of their website and downloaded (and installed) the DRV_ZC0301PLus_070305 driver. I then opened up Photo Booth, and was able to select the Vimicro camera as the video source. What I should have done was just try and access the Microscope using Photo Booth before I installed the driver, as I half suspect that there was no actual need to install that driver.

This is quite annoying for me as I naturally try and use the command key for this. To fix this put the following in your .emacs file.
