[Wizard] PSUs

[Mike Fineberg]

If anyone is interested for more information on the PSUs that come with the Wizards:
A quick search on Google revealed this:

Interestingly wide range of input: 90V -> 264V AC [slightly wider than on the package], 47Hz -> 440Hz (concert 'A' ;-)  Power specs: 5V, 4.0A, peak: 4.5A, Output power: 20W

I've nearly finished my car-mp3 player... All that remains is a 12V-5V PSU and drilling holes for the audio sockets.  I'm running DOS7.x/4DOS and MPX Player 1.48w.  128kbps MP3s show ~50%-60% CPU usage, with 56kbps ~25%-29%.  I have the audio-out hooked up to a small 'soundfeeder' FM transmitter currently taped to the outside of the box for linking with my car's absolutely pathetic stereo.

I currently have 9 dos based mp3 player programs, and have narrowed my selection down to two - MPX and XTC-Player.  XTC is a little prettier, but MPX is more command-line configurable.  No drivers or anything are required to get this box going.  A cut down version of this setup would be ~400kb for the player, ~50kb for the OS. (really just command.com)

I have it setup to use a boot menu with a 5 sec delay to go to automatic play.  In under 30 seconds from plugging the power cable in, it will start playing from where I left it last time... a little more tweaking and I'll be happy.

Follow up note: I've tested my iPAQ's wall socket PSU (a Phihong plugpack PSU [100-240V -> +5V 2A (max total output 10W)] with the Wizard, and it didn't break under the strain of bootup. (I had long ago modded my plugpack with a 2.5mm DC plug (the same as the wizard uses) so I could use a homemade 4xAA battery pack as a battery extender for my iPAQ).
