Can someone instruct me on how to connect the Wirz Electronics LMD18200 H-bridge board to the Handyboard's motor control IC socket, which pin of the socket hooks to which pin of the H-bridge board. Any help would be grate. Thanks (27 years ago, 24-Jan-98, to lugnet.robotics.handyboard)

Hi, I got a bag of HC811E2's and would like to know if they can be used with the handyboard to replace the HC11A1. Thanks, Quinn Marshal (27 years ago, 24-Jan-98, to lugnet.robotics.handyboard)

I once heard of a competition where the objective was to build a solar-powered device that would shoot ping pong balls as fast/far as possible. Does anyone know of links to information on this contest? Thanks, /Max (27 years ago, 22-Jan-98, to lugnet.robotics.handyboard)

First of all, is it even possible to use an E2 68HC11 variant w/ the HB? And if so can I d/l to it without having the LCD attached? As it stands now, I receive an error that the board is in the wrong mode using HBDL.exe while trying to d/l the (...) (27 years ago, 21-Jan-98, to lugnet.robotics.handyboard)

Hi I don't have any objection to putting the modified files up for general download - I only added Julian's code to the 3.1 source... I also modified the "boot" message so that it is obvious that you are running the new PWM code. I've changed the IC (...) (27 years ago, 21-Jan-98, to lugnet.robotics.handyboard)

i have teh sensor hooked up, and I didn't test it much yet, but so far, I am getting a clicking sound when I run it, but the values appear to be completely random (a lot even negative).

Scott, Thanks for incorporating Julian's changes into the 3.1 pcode. In fact, if we can have Julian's permission and yours as well, Scott, we'd be very interested to be able to redistribute the improved pcode with IC 3.1. Scott and Julian, would (...)

Hi I've ported the changes (Julian Skidmore's mod) to the IC 3.1 pcode source code: (available from ftp://newtonlabs.com...ode31.exe) But I don't have anywhere outside a corporate firewall to put the files (a new pcode_hb.s19 and a modified lib_hb.c (...)

Hello everyone, From my mail yesterday: (...) This is a quick note of apology for referring to the Handyboard as "Randy Sargeant's Handyboard" (thus unintentionally downplaying Fred Martin's contribution.)

I haven't seen the schematic you're refering to but I believe you can use the +5V bus already on a standard HB. Just connect your PWR/GND to one of those headers "below" one of the A/D inputs. I did this before and it worked. Apparrently, the 1A +5V (...) (27 years ago, 19-Jan-98, to lugnet.robotics.handyboard)
