Hi, I got my Handyboard up and going and was trying the following code for driving my motors. (Figure I would try known code before forking out on my own). The code I got from the 'Inspiration to implemntation' book. Anyways it does not seem to (...) (26 years ago, 2-Dec-98, to lugnet.robotics.handyboard)

Yeah, I remember seeing that one; I may actaully have the info at home... Anyway, an R/C servo has a hard stop to limit travel because the electronics use a simple potentiometer on the output shaft for position feedback. These pots typically have (...)

(...) I put together a page with detailed instructions that has been used by a number of high school students without any problems. The robot is based on a Basic Stamp but the servo modifications are easy and work with any controller. (URL) (26 years ago, 1-Dec-98, to lugnet.robotics.handyboard)

Howdy Folks :) I remember reading a web doc a while ago on how to convert servos so their shafts can rotate more than 180 degrees... It was a nice doc, with pics, schematics, and everthing... but I lost the URL... :( Does any one know what doc am I (...) (26 years ago, 1-Dec-98, to lugnet.robotics.handyboard)

Hi I did the port of the smoothpwm stuff into the IC 3.x source code. The Newton Labs ftp site has the smoothpwm files available from: ftp://newtonlabs.com...mooth-pwm/ If someone can get me the code for the FP fix, I'll see if I can get a new pcode (...)

I'm replacing my aging home PC with an iMac (look at my email address: I can get one dirt cheap!) and I'm wondering if I can use it to pilot my trusty HandyBoard. Anybody have any experience in this area? I'd like to throw away the PC... The iMac (...) (26 years ago, 1-Dec-98, to lugnet.robotics.handyboard)

To convert from 0-3 to 0-5 I would suspect that all you need is a 2N2222 NPN transistor with a couple of resistors to bias it. For example: +5volts 100 ohm resistor collector ---...---0-5 input 0-3v output -----1k resistor ----- base emitter 0volts (...) (26 years ago, 30-Nov-98, to lugnet.robotics.handyboard)

I have a device that uses 0 - 3V logic levels for the data output. What can I do to convert the output to match the 68HC11's 0 - 5V logic level? Thanks for the help, Dave (26 years ago, 30-Nov-98, to lugnet.robotics.handyboard)
