Today i got a chumby for christmas and found a cool trick to make it truly wireless using only a 9 volt.
Step 1: Stuff you'll need
All you need is a chumby, a 9 volt battery and candy (optional).
Step 2: How to make it wireless
First, flip your chumby upside down. There is a little velcro thingy, so open it. And what do you know? Theres a 9 volt battery snap. Connect the 9 volt and turn it on! Now you have a truly wireless chumby! I would not always have it running off a 9 volt because it will drain pretty quick. This would be use ful at coffee shops, etc.
