Why 2.x?: This is the second generation of these plans. The first generation was never released except internally.
Why "Lizzy?": Comes from a talk David Ross (Atlanta Veteran's Administration R&D) gave at the Boeing workshop about how the Model T Ford was nicknamed the "Tin Lizzy." Everyone adapted it to whatever task needed to be done: winching wagons, pumping water, taking the family to church, etc. It is my hope that these instructions will enable folks to make wearables that do tasks we never imagined.
There is now a mailing list, firstname.lastname@example.org , for those who are interested in making a Lizzy. To subscribe, send a message with the word "subscribe" in the Subject: field to
To unsubscribe, send the word "unsubscribe" in the Subject: field to the email@example.com If you want access to the mailing list's archive, send "archive help" in the Subject: line to, you guessed it, firstname.lastname@example.org
In the event of an address change, it would probably be the wisest to first send an unsubscribe for the old address (this can be done from the new address), and then a new subscribe to the new address (the order is important). Do not send multiple (un)subscription or info requests in one mail. Only one will be processed per mail.
An independent, threading archive of wear-hard is kept by R. Paul McCarty at wearables.blu.org (no relation).
Thanks to the members of the MIT Wearable Computing Project who suffered through the earlier versions of these instructions while making their machines. Many of the small tricks that make the design robust come from them.Copyright 1997, Thad Starner and MIT
