After my first 10,000 miles around the US on the Winnebiko,
leading to the book Computing Across America (now out
of print), I teamed up with a lovely woman named Maggie and
pedaled 6,000 miles down both coasts of the US… then we continued
for another 16,000 via school bus. This all took place between
1986 and 1989, bridging the gap between that first exuberant trip
and the BEHEMOTH epoch, and during that time I posted 55
chapters on the GEnie network. I always meant to use this as the
source of a sequel to the first book, but never got around to it (and
probably never will). There are some wild stories here, and lots
of cultural vignettes of late-80s America from the perspective of a
pre-Internet computerized recumbent bicycle.
WANDER Software168K Zip File
||The WANDER system is a spinoff of the Microship
project, developed for the National Science Foundation's "Wireless
Test" project. We installed Linux on an Octagon PC-500
single-board computer, and packaged it in a Pelican case along with
power management tools, LCD/Keypad, and basic I/O... and it can talk
LAN or Globalstar satellite phone at 9600 baud. You can read all
about it in our Embedded Linux Journal
This zip archive is the complete WANDER software package (other than what's in the Linux distro, of course!). Mostly written in Perl by Ned Konz, it includes all data collection code, GPS sentence parsing, Berkeley DB interface, channel management, a simple graphing package, Webmin front-end cgi scripts, database export tools including satellite email, local UI management, and the C program for a PIC-based solar power and battery management system that even schedules the Linux board. All this is well-commented and tested code; if you're designing a system that even slightly overlaps WANDER, then this will pay for itself.
Sexbar Design Package
||This covers one of the most useful
spinoffs of Microship development: the serial crossbar
network. Presenting a command-line interface on one end and a
matrix of DB-9 connectors on the other, the Sexbar eliminates the
nightmares of random RS-232 connections... swapping pins 2 and 3,
fiddling with gender changers, and assembling chains of cables to
get something to work. If the plugs fit and the baud rates match,
any two devices will talk — it even figures out which pins
transmit and which receive, then connects them accordingly! This
scalable design provides 31 channels, and up to four simultaneous
bidirectional connections can exist among any of them.
This book includes schematics, FORTH code for an embedded 68HC11 controller, and enough design theory to port it to another platform if you wish. Introduction here.
The Microship Trimaran22 pages
||This document is a moderately detailed
description of the Microship substrate: the micro-trimaran
including the hulls, deck fabrication, crossbeams, hatches, and other
basic boat details. We stop short of discussing the sail rig (a
modified stock unit from the WindRider 16 trimaran), auxiliary
pedal/electric propulsion systems, landing gear, hydraulically
controlled rudder, cockpit features, or electronics; these will be
covered in other publications of this series. The intent here is
to provide enough information to help fellow boatbuilders overcome
the initial hurdles in small multihull fabrication by revealing the
fundamental structural and nautical design features of the basic
