SimpleSpeaker for iPod Alarm Clock

MadsonLine Portable Power Devices
Piped music with SimpleSpeaker for iPod.
SimpleSpeaker is a very small and light stereo loudspeaker which works without batteries. It can be connected directly with the headphone jack of your iPod without using any audio cable.
The foldable design of SimpleSpeaker allows it to use the ipod both in horizontal and vertical position.
The SimpleSpeaker packs and travels easily and enables to use the iPod even as a travel alarm clock.

This sells for $10, probably cost $2 to make. Authentic Chinese packaging, I think this was made for the Chinese marketplace. Horrid tinny sound. Comes with two speakers, one would be plenty. At maximum iPod volume this unpowered speaker puts out just enough music to awaken a light to medium sleeper. It is compact, though the sound jack always protrudes.

For the price, weight, and size it's worth sticking in luggage so the iPod can be a travel alarm. There are much nicer speakers for a bit more money and heft. I think for this purpose a "Lollipop" mono speaker of a bit better quality with sound jack that rotated internally would work better and could sell for $12.

macosxhints: Eject stuck CDs using open firmware or muouse

macosxhints: Eject stuck CDs using open firmware
I had a CD get stuck in my slot-loading superdrive Aluminum Powerbook, running 10.3. The CD became unresponsive and not recognized by my computer at all! Here is the fix.

Hold Control-Command-Option-Eject Button; this will shut down your computer. Turn the power on with the power button and hold Command-Option-O-F -- this will boot you into open firmware. Now type eject cd and wait until the CD pops out. Type mac-boot and you are ready to rock!

[robg adds: As mentioned elsewhere on the site, you can also try holding the mouse button down during boot to force the system to eject any inserted CDs.]

Pennsylvania Amish Area
Lancaster, Pa.
Although it is rarely billed as such, the Amish area here is a fantastic place

Inverness, Fla.
On 46 paved miles along the Withlacoochee River from Citrus Springs to Trilby,
