  the Expansion Board 3.0 beta program
 
Dear all, The design for the Handy Board Expansion Board is done, and I am now sponsoring a limited beta-test program. I know that many of you have been waiting a long time for the board, and I will be asking most of you to wait a little longer as (...) (26 years ago, 14-Jun-98, to lugnet.robotics.handyboard)
 
  config 0x0C
 
Hi there, I have used a 68HC11E1 with my HB for quite a while now and it works fine with it. Now I replaced it with a 68HC11A1FN and it wouldn't let me download the .s19 file with HBDL anymore. It stops when downloading the program and says: Invalid (...) (26 years ago, 12-Jun-98, to lugnet.robotics.handyboard)
 
  *** pyroelectric sensors ***
 
Hi I want ti make a robot follow people around, How many pyroelectric sensors do I need on the robot? I would think TWO one on either side in front? Someone told me only one is needed? can anyone shed some light on this subject? Thanks -MIKE (26 years ago, 12-Jun-98, to lugnet.robotics.handyboard)
 
  pcbug11 crashes
 
Hello, I can't seem to get pcbug11 to run from Windows 95 (full screen dos-mode). I've downloaded every possible version and I always get: "runtime error 200 at 20FF:0091" when running pcbug11.exe. Has anyone encountered this before? Thanks in (...) (26 years ago, 11-Jun-98, to lugnet.robotics.handyboard)

  Multi-tasking under IC (Freeware version)
 
I am somewhat new to handyboards and IC, so bear with me if this issue has been dealt with before. (I did check the FAQ and "some" of this list's archives prior to posting.) Under IC (the freeware version) cooperating processes communicate using (...) (26 years ago, 11-Jun-98, to lugnet.robotics.handyboard)
 
  Re: motor selection
 
(...) From the archive: Date: Tue, 3 Mar 1998 17:12:30 -0500 (EST) (...) I have a sonar mounted on a panning servo, and I just bought an el-cheapo Cirrus CS-50. (It is functionally equivalent to a JR/Hitec JR-507 or HS-300). It works fine, although (...) (26 years ago, 11-Jun-98, to lugnet.robotics.handyboard)
 
  RE: input impedance
 
Never mind, I have managed to solve the problem by cutting the trace between the 47k pull-up resistor and the sensor input. -----Original Message----- From: Joe Martin [SMTP:joema@mpx.com.au] Sent: Wednesday, 10 June 1998 18:29 To: (...) (26 years ago, 11-Jun-98, to lugnet.robotics.handyboard)
 
  D/A converter
 
"Hi", from Hector Noriega, I am trying to send a data byte from port C out to a D/A converter faster than 1KHZ (target about 10KHZ) . I wrote a test subroutine in assembly code but I can not enable the address decoder using port B for the msb and (...) (26 years ago, 11-Jun-98, to lugnet.robotics.handyboard)
 
  onboard IR receiver
 
the problem that i was having with the onboard IR receiver is that the codes that i retrieved from the ir_data() function were inconsistant from the same remote control button. the error was usually manifested in multiples of two, which lead me to (...)

  Re: motor selection
 
Where is your source and how do the Cirrus compare to Futuba in price? At a local hobby store in Houston I bought 2 Futuba 3003 (I think) that are the replacements for the 148 which I believe are no longer being made. They cost me about $13 but list (...)

  Re: input impedance
 
(...) Hmmmmmm.. as I recall, there are 47k pullups on those inputs. These are used to condition the signals when used as a digital input. The 'HC11 pink book suggests that any input resistance of greater then 10K will "...degrade A/D accuracy." The (...) (26 years ago, 11-Jun-98, to lugnet.robotics.handyboard)
 
  Re: Question about Sharp IR demodulators
 
I had a similar experience, except that all my IR demodulators were from Radio Shack; two were some I'd gotten in a "grab bag" quite a few years ago, and the others were brand new. The original one reacted to 40KHz the way you describe yours doing - (...) (26 years ago, 11-Jun-98, to lugnet.robotics.handyboard)
 
  motor selection
 
Can anyone tell me what is a good servo motor? I haven't had any experience and would like some input on names of servos to choose from. I am looking for a model number and company. Chris Rhodes (26 years ago, 10-Jun-98, to lugnet.robotics.handyboard)
 
  Question about Sharp IR demodulators
 
Hi everyone, First, sorry for the blank message just now -- hit the send button instead of the cancel. I'm working on a project where I've got robots hunting targets equipped with a 40 kHz oscillator circuit which is continuously pulsing an IR LED. (...)

  Extra HB For Sale
 
I have one extra HandyBoard that I will sell if anyone needs one. It is a fully assembled and tested board with Serial Interface Board and cases. It has never been used in a project (about 2 months old). I built two of these and find that I am only (...) (26 years ago, 10-Jun-98, to lugnet.robotics.handyboard)
 
  Re: Windows NT experiences?
 
I use IC 2.8 under NT with no problems. Before you can use IC under NT, you`ll have to turn off the COM-port your HB is connected to under NT, or else NT won't let IC use it. You can delete the COM port in the `ports` part in you configuration (...) (26 years ago, 10-Jun-98, to lugnet.robotics.handyboard)
 
  input impedance
 
Does anyone know the impedance onto the sensor inputs on the HB and/or any suggestions for setting them to receive signals sent at 220K Ohm. Joe Martin joema@mpx.com.au (26 years ago, 10-Jun-98, to lugnet.robotics.handyboard)
 
  Re: Windows NT experiences?
 
I've been using IC3.2 on Windows NT/4.0 with very few problems. I used to have IC lock up occasionally, but only when I disconnected the Handy Board at weird times. Once I was more careful about disconnecting the Handy Board only when IC was at a (...) (26 years ago, 9-Jun-98, to lugnet.robotics.handyboard)
