It works! Touchscreen repaired, PCMCIA works with 5V, can boot a Debian_arm off my 1GB microdrive! Just did a power-meassurement

power

• voltage: 15.72V

• booting up from flash: 0.5A
• normal operation: 0.4A
• non-exxessive microdrive-access: 0.6A = 9.432W
• non-exxessive 32MB-CF-Flash-access: peak 0.54A
• no microdrive, sitting for a while: stable at 0.35A = 5.502W

• bootup from flash: 0.16A
• doing nothing for a while: 0.08A = 1.2576W
• microdrive-insertion: peak at 0.3A = 4.716W
• 32MB-CF-Flash-insertion: peak at 0.14A

28.08.2002 - just meassured the power-draw

27.08.2002 - repaired the touchscreen by making a better cable and using the right plug instead of soldering directly to the mylar-cable.

It works! Touchscreen too ;). Need to calibrate touchscreen and work on the software.

25.07.2002 - touchscreen-cabvle broke off. :( I'll have to find a better way to connect to the mylar. Local electronics-shop says soldering to it is not going to work, like I didn't know.

27.07.2002 - did the 5V-pcmcia-modification to the tux.

28.07.2002 - pcmcia works! Finally more then 4MB!

20.07.2002 - finally done with the first tests at the university I got to solder again. Replaces the wire+hotglue power-plug with a real mini-din-plug (They finally had them in the local electronics-shop). Still have to compile xcalibrate against ulibc to calibrate the screen.

IT WORKS!!! I hope to present everything working at Linuxtag this weekend.

02.07.2002 - Got around to work on it again. Found the problem with the touchscreen, it works now but is totally uncalibrated. IR-keyboard broke during LinuxTag? due to mechanical stress in real world usage but is long since repaired and reinforced with resin.

• touchscreen-connection:
  

• touchscreen-cabe to 40wire display-cable:
  

• 2cables because they invert front+back row :(:
  

• 4 new contacts to display-connector:

07.06.2002 - postponed going to LinuxTag? until tomorrow, IR-keyboard works again and has a hole in the front, hid all the cables from view, first usability-tests showed I need to route the display-cable another way (they have no 1.35mm 40wire cables in the local electronics-shop anymore so that will happen after LinuxTag?) but otherwise very robust. Definately rain-proof (the hard way). X-winows is running. touchscreen will work when the final display-cable is done.

WOC II

WOC II aka TuxVest?

The tuxscreen is back with the living. Screen is working again. Work continues. 3.3V- and 5.0V-supplies are alife and kicking (no test with tuxscreen yet, no fitting plug found), only the display-case+cable are left. I hope to present everything working at Linuxtag this weekend.

IT WORKS!!! I hope to present everything working at Linuxtag this weekend.

06.06.2002 - Extending the display-cable works and the mobile-power-supply can boot up the vest from a battery! Temporary display-case holds (some plexi-glass and lots of tape), I'll need to make a better display-cable later but this will do for the time being.

The power-supply should be a 5V switching-voltage regulator with a Dell-laptop-battery and a linear regulator to make 3.3V out of it. This will be hingly inefficient but be replaced with one 2-output or 2 switching high-efficiency regulators once I know where to get some in Germany. (The local electronics shop does not havy any not does orders.)

The case is a light vest with a new inside-pocket for the display and the dual-pcmcia-slot accessible in one of the breast-pockets. (is practical and looks good and unsuspicious). The computer can be taken out for washing. An inner layer of cloth hides the components and can be taken out of the way for maintenance and washing.

The Power-supply is currently preliminary using a switching 5V-regulator and a linear 3.3V one. Finally it will be powered via 2 LiIon? cell-phone-batteries (very leightweight) and an optional external laptop-battery. I am planning to try to use a cell-phone as a charger while in use. Meight as well use it as a cellphone too. ;)

06.06.2002 - 5V-supply now working too, first tests at making the display-cable longer failed but I'll try again.

The "case" works pretty well, It's finished; The system does not want to boot up at all anymore, guess I finally did it. :(
I also have not tested the power-supply yet. The IR-receiver is currently broken off and I neet to solder it on again.

20.5.2002 - redid some seams on the vest with a pocket-sewing machine, looks much better then by hand. ;)

23.05.2002 - Found the time to test why the backlight does not activate with a borrowed screen. Bad news: the thing does not boot up at all anymore. Even though it just lay here doing nothing. Confirmed that it has 3.3V and 5V, circuit-breaker is intact, no mechanical damage. Guess I did it. :( I'll try if it's just the bootloader by using my (with reat foresight bought) JTAG-board but I don't see a chance.

This is a new system I am building for everyday outdoor-usage. It must withstand rain while not in use, sweat, allow me to run and jump and be light and next to unnoticable.

It weights nearly nothing (aside from the kilograms of other electronics that fills my pockets anyway) and is washable (if you take the computer out first ;) ).

09.05.2002 - the vest id done. Got a nice cloth for the inner side and made a padded pounch for the display with an extra-large opening (required for easy use).

• finished Vest inside-out:
  

• again, better angle:
  

• display-pounch, extra large, no sharp edges:
  

• CPU-pounch on the inside:
  

• easily accessible from the underside:
  

• me, myself and the finshed vest.:

09.05.2002 - An working on the vest again, cut the cloth for the inner layer. I'll move the display-pounch to the other side, it's not comfortable this way. Next will be the power-supply.

03.05.2002 - PCMCIA does not work despite a new tuxscreen-root and kernel. No 5V hack yet but a microdrive should work.

comming soon.

29.04.2002 - the Phone is there and I flashed it with Linux. Nice.

30.04.2002 - www.TuxScreen.org reports Microdrives to run (only 3.3V) but somehow my swystem resets when I insert one. :( Tried to build a new root with a newer kernel but my linker or libc is broken. Cannot create x86-executables (illegal memory access). why???

01.05.2002 - I took apart the phone, build the "case" and a temporary case for the display. Later the display somehow broke(backligt stays off) and I took apart that case while searching frantically for the reason.

02.05.2002 - still no sign as to what caused the backlight to fail. :( Wanted to present the system tomorrow.

comming soon

Introduction

parts

The power-supply should be a 5V switching-voltage regulator with a Dell-laptop-battery and a linear regulator to make 3.3V out of it. This will be hingly inefficient but be replaced with one 2-output or 2 switching high-efficiency regulators once I know where to get some in Germany. (The local electronics shop does not havy any not does orders.)

The case is a light vest with a new inside-pocket for the display and the dual-pcmcia-slot accessible in one of the breast-pockets. (is practical and looks good and unsuspicious). The computer can be taken out for washing.

The cpu-core is a takes apart TuxScreen. I did not separate the boards (this enough) but am planning to extends the display-cable.

The display is the 7.7" touch-screen from the TuxScreen with the case removed (too much air in it) and I am building a new case with a plexi-glass back and I plan to cast the sides out of epoxy and glass-fiber.

There is also an IR-keyboard comming with the TuxScreen. The receiver will have a small hole somewhere on the front. I'll experiment how to conceal it first.

Changes

comming soon.
