 | | first step in assembly of the handy board...
|
|
I'm kinda new at this...Can anyone tell me what voltage I should be checking with my multimeter(1000 or 200 or 200M etc..)? I'm on the first testing stage of the main assembly of the handy board and I get no voltage and GND and +5v spot, also my led (...) (25 years ago, 18-Apr-99, to lugnet.robotics.handyboard)

Dear Handy Board user, I have several question regarding the Handy Board, but first I want to ask you about the connection between the Serial and the CPU Board. 1. I saw in the part list the use of a RJ11 6/4 top entry at the CPU side and the use of (...) (25 years ago, 18-Apr-99, to lugnet.robotics.handyboard)

For all of you (2?) who have been anxiously awaiting the Handyboard library for the GCC compiler: It ain't ready yet. :-( Keith Hearn and myself have been working hard at different pieces of it, and we're hoping to have a merged library sometime (...)

Hello all, I want to power some twelve volt gearmotors (The kind currently available from Acroname) with the H board without extensively (or permanently) modifiying the H board. My plan is to use some MOSFETS that have a low voltage gate threshold (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

I'm having a lot of trouble with the first assembly of the handy board(4.1)...I installed all the parts, but the led does not light and I get zero voltage at GND and +5v...What could cause zero voltage accross the board??? I already switched D3(like (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

(...) I have started working on an expansion board version of the compass code. I won't have it done before fall probably (unless is snows or something really bad). I am involved in another huge project right now. My thoughts are to have the compass (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

Hi Doug: I built a 12-servomotor walking robot using two SSCs - their interface with the HandyBoard is well documented, and ICB drivers are available on the webpage. I communicate with two SSCs (www.seetron.com) via one serial line connected to PA7 (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

| | design alternatives: servo control and power source
|

Hello, I am planning to build a robot based on the Lynxmotion Hexapod II and Big Grip kits. There will be 12 servos for lego control, 2 servos for the manipulator, and 2 more for a camera pan/tilt unit. Everything appears fairly straightforward, (...)

Hi everybody! I've been running both the Polaroid sonar sensor and Vector 2x digital compass on the HB without the expansion board. I'm using Kent Farnsworth's older sonar driver code that is designed for the motor driver output ports (U11). The (...) (25 years ago, 16-Apr-99, to lugnet.robotics.handyboard)

(...) I don't have the Ferrettronics chip datasheet in front of me but some off the cuff calculations: 2400 bps/10 bits per byte=240 bytes per second each servo will require at least 2 bytes (servo # and position) 16 servos * 2 = 32 bytes for each (...)
