Title: Possible Smaller Battery Idea: Suggestions needed
Post by: swayze1 on November 20, 2008, 12:28:48 PM
I am working on my first ir pen for the whiteboard, and had an idea on how to get the batteries into a smaller pen. I remembered the 9v battery hack from instructables (split open the case to find 6 smaller 1.2v cells inside) and sure enough, the batteries are small enough to fit into a smaller pen. Has anyone tried this before? Any thoughts on this idea???

After looking at this it looks like the AAA cell is 9.5mm and the cell inside of a 9v is about 8mm so it is a bit smaller. Which is probably what they use in AAAA batteries.

So you could just use AAAA batteries :)
