While trying to unload some IS1U60 IR receivers, I found the sharp data site. It turns out that the IS1U60 has a center freq of 38 khz, while 40khz is is well within its pickup range, I wonder if changeing the circuit on the HB to 38khz would (...)

| | TCNT register !
|
|
I want to know if the time we get from timer (TCNT) is in second or milisecond. I was trying to run the handyboard for my first time, and I am confusing about the power supply, I don't know if the power supply should be plugged in the handy board (...)

(...) The battery goes to the (+) (-) spots, and the charger plugs into either the Handy Board itself (near the frob knob) or on the serial/battery board. The system time, while running IC (which is what I assume you're going to do) is in (...) (29 years ago, 11-Apr-96, to lugnet.robotics.handyboard)

| | 4 line LCDs and other LCD questions
|
|
Dear HB suppliers: Can anybody sell us bigger LCDs for the HandyBoard? I need at least 4 line LCD or other similar type. It will be used in complete darkness, so it should be illuminated. Thanks.

(...) HB experts, correct me if I'm wrong, but if someone wanted to use an LCD bigger than 2x16, wouldn't the pcode have to be recompiled? I know that in the pcode.asm file there is reference to displays up to 2x80 (of which I have 4 and none work (...) (29 years ago, 12-Apr-96, to lugnet.robotics.handyboard)

Does anyone know how to activate the servo on HandyBoard with IC? (I am going to use the Polaroid Sonar Ranger when it gets here.) When I try to load 'Servo.C', the supplied program, I get 6 or 8 errors of unassigned lables. I assume that (...) (29 years ago, 12-Apr-96, to lugnet.robotics.handyboard)

(...) You need to do a 'load servo.icb' before you do the 'load servo.c' command. The .icb file contains the code described in the servo.asm file, in a binary format. The code in the servo.asm file does the actual work of running the servo output. (...) (29 years ago, 12-Apr-96, to lugnet.robotics.handyboard)

| | h-bridges, current info
|
|
I'm trying to figure out a couple things. First, can four NPN transistors be used to form an h-bridge? I was looking in a book, the Robot Builder's Bonanza, which features a circuit which uses four TIP41 transistors. However, don't most h-bridges (...)
