The Juicebox is a cheap (~$5) failed toy video player.  But, it has been hacked by many people and much is known about it.  I'm interested in using it as a wireless weather station (that also shows photos).  Here's scheme:

The Juicebox is easily modified to read SD cards and become a photo viewer or MP3 player.  I'm just looking at the photo viewer aspect.  Mattel even sold an SD card adapter kit, you can probably still buy.  But, the unit I bought from Amazon.com (price actually increased to $10)came with a sample clip (Vans Triple Crown) (the clip that comes with the player is just a dummy and doesn't have a card edge!).  This sample clip was easily modified to connect to an external SD card:

  This is the wiring diagram I got from here.

Several sites say that the card only reads up to 512 MB SD cards, but it works just fine with my 1 GB card.  I think more important is the cluster size.  Probably the same limitations as with the Propeller's SD card interface (both only read the root directory).

The above mod makes the unit a Digital Photo Frame.  However, it only shows pictures in it's own ".jbp" format, headerless 12-bit (rrrrggggbbbb).   There is a java image converter here.

My plan is to share the SD card with the Propeller.  I believe this scheme may work with any Digital Photo Frame (going to test soon!)  It took some work to figure this out, but here's what I have working:

I now have a working driver that copies the Prop's VGA screen (30 columns x 15 rows) onto the SD card while monitoring the JB's control of the SD card clock signal.  It can work with the Juicebox in slideshow mode with 2 s refresh.  Here the code and a picture of the setup:
