| (...) Oh, it's possible (if you put the batteries someplace else)... there's more smarts than an RCX in a high-end wristwatch, and that's a smaller footprint than you specify. The trick is that to do it, you'd have to build it from the chips up, (...) (20 years ago, 25-Oct-04, to lugnet.robotics)

You can get *tiny* computers that would easily fit in this kind of tiny space - but the RCX motors need 9 volts - you would need (...) (20 years ago, 25-Oct-04, to lugnet.robotics)

| (...) Any idea on how I2C compares to 1-wire? I know that there 1-wire is being considered for some open-source home automation schemes because of the extremely low cost of interfacing, and the data rates seem comparable 115k for 1-wire vs. 100k for (...)

| (...) I2C is much faster (100 Kbit I2C is the slowest, vs 14 Kbit 1Wire), more reliable, but much shorter distance. Newer I2C can be 1 Mbit or more. (...) 1Wire will never do 115 kbits reliably. The 1Wire overdrive option is not reliable and few (...) (20 years ago, 26-Oct-04, to lugnet.robotics)
