You're in Wearforge -> Wearhard -> Nomad1Project
NOTE - This page is no longer my primary page for tracking my wearable project. I have moved my project page to my personal wiki at my own domain. The data here will get updated from time to time, but my primary site will always be the most current. You can visit my project page at http://www.pascal.org/wiki/space/Nomad.
Nomad I is my first wearable system.
Nomad1 being worn:
 
- Advantech PCM-5822 @ 300Mhz
- 128Mb RAM
- IBM TravelStar? 40GB disk
- CyVisor? HMD monocle hack
- 800x600 @ 16bit
- Useable with X11 and Linux framebuffer (100x43 text)
- Twiddler II chording keyboard with mouse
- External USB keyboard/mouse when stationary
- 802.11 wireless networking via PCMCIA
- Garmin GPS-35 (low voltage model)
- Custom 5v and 12v power system
- Protected battery and external power inputs
- Dual Toshiba PA2485U 10.8v @ 5600mAh laptop batteries in
parallel
- Approximately 7 to 9 hours of use depending on load
- Easy replacement of batteries without shutting down system
- External power input available for use while hot swapping
batteries
- Hauppauge USB video capture/tv/radio using USBVision drivers
- s-video input
- audio input
- Television (yes I've watched TV on my wear-able)
- FM radio
- RedHat? Linux 7.x
- I'd rather use Debian for the wearable but there is no
stable release using a 2.4 kernel.
- Sun Java 1.3/1.4
- Sun Jini
- jAugment
- gpsdrive/gpsd
- Escher's Puppet
window manager to replace Rat-Poison, which I had been
using.
- MIT RememberanceAgent
- Opera web browser
- Well worth the $35
- Very usable mouseless navigation of web pages
- Student discounts (whoo hoo)
- Use as a research vehicle for wear-able UI and HCI
- Use as a research vehicle for augmented prevasive computing
- The wear-able acts as an interface to local pervasive
computing resources
- Central loci for personal info and perferences
- Use as my primary computing platform
- Replacing desktop system
- Using alternative UI approaches
- Integrate with my home, work, and car networks.
- 04/2003 - I'm seriously looking into purchasing a HP/Compaq
TC-1000 tablet PC as a replacement for my dead PCM-5822. Check
the reasons
why at my wiki.
- 02/2003 - On a whim I contacted Advantech to see what they
could do with my PCM-5822. To my surprised I found that my
board is still in warrentee and I even got a RMA# to
ship it back to them.
- 08/18/2002 - While I was fixing my broken cable, I found
an old electric shaver with a nice vinyl case. I noticed
the top would fit nicely around my Cy-Visor display. I
placed the plastic cover of the razor inside the cover
of the case to strengthen and protect the display and to
make the cover crush proof. Works nicely, though I wouldn't
call it "covert"
*grin*

- 08/18/2002 - I replaced the cable between the Cy-Visor
control box and display for yet a third time. This last
cable lasted all of four months. At $75 for a replacement,
I'm starting to wonder if the Cy-Visor is something I
can afford to use now that I am a student.
I love the Cy-Visor's 800x600 color display, but if the
cables are going to be this fragile I can't recommend it
to anyone as a display for their wear-able. How does the
manufacturer expect to stay in business, unless their
business is repairing their product after sale.
- 08/12/2002 - I'm trying an experiment with painting the
inside of the HMD with the display black except where the
display shows through. This should reduce the amount of
light coming in from around the display and help increase
readablity.
- 07/2002 - Spent the month moving into and working on
our new home (well, its 80 years old, but its "new" to us) and preparing to start school in the fall. Continued
working on jXWM, my experimental Java based X11 window
manager.
- 06/20/2002 - Started work on a new window manager,
jXWM
(Java eXtensible Window Manage), to serve as a flexible
development component for wearable user interface ideas.
Switched to using
Escher's Puppet
window manager to get a feel for how useful a Java based
X11 window manager would be and how well the Escher X11
classes work.
- 06/2002 - Spent the month prep-ing and moving out of our
N. California home and moving back to Fargo, North Dakota
to return back to school full time.
- 06/04/2002 - Upgraded to a 40Gb IBM TravelStar? disk drive
for more video/audio capture space (not in use yet, but
preparing for school this Spring)
- 05/28/2002 - Upgraded to RedHat? 7.3 to use newer kernel to
avoid ptrace security risk.
- 05/10/2002 - Switched to ratpoison mouseless window manager
- 04/2002 - Repackaged wearable to fit into the inside hip
pocket of a Scott eVest.
- Built a new custom 5v/12v power board
- Includes 5v/12v power buses to power external devices
- Converted Toshiba PA2486U battery charger into a battery
case. Easily fits into the other inside hip pocket on the
eVest. Power cable runs through lining along the back of
the vest. Helps balance weight distribution.
- Enhance
Escher's Puppet
window manager to replace rat-poison to provide Jini/jAugment
support, scripting, and better keyboard mouse emulation.
- Write a JESS Jini service
to provide rule based monitoring and response to Jini/jAugment
events.
- Write a Linux driver for the Seiko Instruments, Inc's InkLink
USB device to provide a real-time method of collecting hand
written notes for classes.
- Implement an OCR solution for real-time and post processing of
digital ink notes and captured images.
