This weekend I also got the OOPic to talk to my Palm Pilot via Serial connection. Works great! I can send it commands through a palm pilot. But I haven't decided which one to use - a laptop PC, or a palm. Programming the laptop is a lot easier, but the palm is nice and small, with longer lasting batteries.... decisions, decisions. I will most likely prototype on the PC.
I also started a OOPic related website on Friday. It's at OOPHQ.com. (OOPic Headquarters). If you have OOPic content, feel free to send it to me ;)
