Because the cost of production is low and there is no physical inventory, these are a lot cheaper than the print monographs I tried for a while. At the moment, this is experimental, and I'm not trying anything fancy with authentication and automatic downloads.  There's a Paypal "Add to Cart" button corresponding to each document, and when I get the magic email from their system indicating that I've made a sale, I will send the chosen files to the buyer. (If you don't wish to use Paypal, please contact me for alternatives... I'll take Visa/MC by phone, checks, money orders, Krugerrands, trade goods, negotiable securities, boat parts, and even cash.)

Miles With Maggie

Winnebiko II console    

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 Software

168K Zip File


The WANDER system is a spinoff of the Microship project, developed for the National Science Foundation's "Wireless Field Test" project.  We installed Linux on an Octagon PC-500 single-board computer, and packaged it in a Pelican case along with GPS, power management tools, LCD/Keypad, and basic I/O... and it can talk via LAN or Globalstar satellite phone at 9600 baud.  You can read all about it in our Embedded Linux Journal article.

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

Sexbar connector matrix
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.

Hull-deck seam

Hull sanding
This document is a moderately detailed description of the Microship substrate:  the micro-trimaran itself, 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 Microship.
