Hi. Have any of you guys out there had experienced getting a MEMORY FAULT message from the HB or getting garbled displays ? I really hope someone could tell me what this means and what should I do about it. Thanks in advance. F. Samonte (26 years ago, 10-Mar-99, to lugnet.robotics.handyboard)

(...) Yes it can. (...) Well, without modification, the parallel port can probably do a lot of what you need, although, there are only 8 (12) bits for you to use. A separate processor could communicate through a serial port, and do some of the same (...) (26 years ago, 10-Mar-99, to lugnet.robotics.handyboard)

Great ! I thought no one could have done or imagined something like. The problem, I belive, is that no massive memory storage device (massive: about 1Mb or 2, or 512 KB ...) has an input that can be interfaced with the handyboard or with another (...)

(...) I have a question for you guys. Why are you using the Handyboard to control the car? The SBC332 board on the cognachrome system is a very powerful microcontroller and is fully capable of handling the actuators on your car. As an example, check (...)

I too would really like to use a Mini Hard-Drive on my Handy Board robot. (URL) and Mobile Phone use micro-controllers, don't they? Can a HC11 write/access data to/from HD sectors? If anyone out there has any idea's or info, be sure and let us know. (...) (26 years ago, 10-Mar-99, to lugnet.robotics.handyboard)

Hi all, The Handyboard is a wonderful piece of equipment. Lots of fun and simple and easy to use from a newcomers standpoint. I have learned much from messing around with it and plan on doing so for some time. I am by no means finished. Right now I (...) (26 years ago, 10-Mar-99, to lugnet.robotics.handyboard)

A Taylor series isn't the way to go: they converge far too slowly. Here is a polynomial fit to arccos(x): arccos(x) ~ = 1.5708 - 1.0927 x + 4.358 x^3 - 0.8340 x^5 It differs from the exact value of arccos(x) by no more that 0.08 radians (4.6 (...)
