Kevin You make a very good point, a kit of sensors and associated lesson plans would be great. One like the Arduino Starter Kit would be good, it has a patch board, leads and sensors suitable for the XO mic socket, it has a few output devices we don't need http://littlebirdelectronics.com/products/starter-kit-for-arduino-flex The concern I have is cost. The XO is $188 and most of the target market is very price sensitive. My guess is that it would accept a cost of $10 for a Starter Kit, just my guess. The Arduino Starter Kit would be at least $23.50 if you removed the Arduino and USB cable and added a 3.5mm phono plug with flying leads, probably more, my guess $30 -$35 considering that the per component price goes up for smaller kits. Here is how I calculate $23.50 http://littlebirdelectronics.com/products/starter-kit-for-arduino-flex $59.95 http://littlebirdelectronics.com/products/USB-Cable-A-to-B-6-Foot less $3.95 http://littlebirdelectronics.com/products/arduino-uno-r3 less $32.50 total starterkit less arduinouno and usb cable $23.50 Maybe the next step is to talk to a kit manufacturer like Sparkfun Tony _______________________________________________ IAEP -- It's An Education Project (not a laptop project!)
