 | | Mini-RCX —Andrew G. Meyer
|
| | | Hi, My brother and I have been tossing the idea around of a mini-RCX. We have narrowed our idea down to a two sensor, two motor brick that would be approximately 4X6 studs on top, and about two bricks high. We were just wondering if anyone out there (...)

| | | | | (...) 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)

| | | | | | (...) I don't see a problem with the computer side of things - what concerns me is battery storage and power management. 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 (...)

| | | | | | | | 1Wire vs I2C —Bruce Boyes
|
| | | | | | (...) 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)
