PassBank login
PassBank data
PassBank menu
Where do you keep the dozens of ID's and passwords that you have accumulated over time?   Want something a little more secure than Memo Pad?

PassBank is a password database with a simple encryption/decryption scheme.  This was a project for learning a new language and a new platform, so it's not bulletproof.   The only limit on the number of records is the available free space in RAM.   Copying the database to another Palm with PassBank to read it there won't work: it's keyed to the HotSync User ID.   The security will keep out most of your kids, but not the NSA ;-)

After installing on your Palm, run PassBank. You will be prompted for a password to use with PassBank.  Enter a password and tap the Enter button. You will get the data entry/display screen.   There will be one entry in the listbox, the entry for PassBank.   After verifying your User ID and Password, go back to the Palm application menu and test your password.  You can change the Password for PassBank just as you would any other Item.

You can view, edit, delete, or print an existing entry by selecting it in the listbox or finding it via Find Item.

Select Edit from the menu to use Cut, Copy, Paste, or Undo.

To save changes to an Item, tap the Save Changes button.   If you make changes to an Item and exit PassBank with that Item displayed, the changes to that Item will automatically be saved.   If you turn off the Palm with PassBank active, or an auto-off occurs with PassBank active, it sets a flag to do a save and exit when the Palm is next turned on.   This gives a brief flash of the PassBank screen when the Palm is turned on again and a short delay while the data is saved.   The Palm will then display the launcher screen.  
To delete a displayed Item, tap the Delete button.   You will be prompted to verify the deletion.

To add a new entry when an existing entry is displayed, tap Clear to clear the fields.   When you tap in the Item field, the Save button will be displayed.   Or select Action then Create from the menu. When finished creating a new entry, tap Save.

To print a displayed Item, tap the Print button or select Action then Print Current from the menu.   Selecting Action then Print All will print all the entries.   Items can be printed with or without their passwords.   Blank fields do not print.
(You must have PalmPrint [version 3 for OS4 and lower, version 4.x for OS5] or the equivalent version of SCSPrint from Stevens Creek software to use the Print functions.)

The encrypt/decrypt functions are in the crypto.cod module.   This gives you the option of using better encryption without changing the core program.   In the current version, only the Password is encrypted.  

Download the Palm .prc file: Version 5.1.2   10 April 2005.

Source for this program and a Visual Basic program (with source) to read the database on a PC is available for $10.

What version number changes mean:
  • 2.x -> 3.0 - major functional change
  • 3.1 -> 3.2 - bug fix or added feature (such as support for PalmPrint in 3.2)
  • 3.2.1 -> 3.2.2 - small, usually cosmetic change
Version 5.0 added Copy, Cut, Paste, and one level of Undo. It does better detection of fields that have been changed and need to be saved.
Version 4.5 added "clear screen and save" on power off.
Version 4.4 added "Create" to the menu.
Version 4.3 added the option to Show/Hide the PassBank password during login.
Version 4.2 allowed editing the Item name and provided audible notification of a successful search.
Version 4.1 added the last modification date to the menu.
Version 4.0 had major internal changes to provide for an unlimited number of entries, reduce memory usage, and speed up searching.

This is a work in progress, so come back occasionally to get the latest version.   If you have a "killer" enhancement, send email.

KW Calculator screen Ever wonder if your electric meter provides any information that might be useful to ordinary humans?   What if it could tell you how much power a specific appliance uses?  

How do you read the meter?   You don't have to ;-)

KW Calculator uses the time it takes for the moving dial to make one revolution to compute the total current power being used.   Turning one appliance on or off and taking another reading will tell you how much power that appliance uses.

You need to get the Kh factor from the faceplate of the electric meter.   It will be indicated by a "Kh" marking and be something like 6.3 or 7.2.   This is an indicator of how much power is required to turn the disk one full revolution.   Combining this factor with the time it takes for the dial to make one revolution will give the current load.   See Watt's Your Power? for more information.

To make the timing easy, the program includes a timer that can track clock ticks.   It's accurate to +/- 0.1 second.

Download ZIP file with .prc and NSBasic source: Version 1.4.1   21 January 2008.

Version 1.4.1 updates the contact information on the Info screen.
Version 1.4 saves the most recently used Kh value so you don't have to enter it every time you check your meter.     If you use the built-in timer, it calculates the power used when you tap the "Stop Timer" button.
Code 3 of 9 screen On one of the Palm newsgroups, someone asked if it was possible to generate a barcode on the Palm screen and scan that code. My first thought was that generating the code would be relatively simple, but that the Palm screen was too reflective for a scanner to work with.

Code 3 of 9 is my way of testing that answer.   It generates a 3 of 9 barcode of up to 7 characters on the Palm screen.

Testing with a Symbol SPT1500 laser scanner proves that the barcodes are valid, as a screen print of the Palm Emulator (on an old HP inkjet printer) scans correctly.

My assumption about the reflectivity of the screen was also correct, at least for the unit used in testing (Palm IIIxe), as the scanner sees no barcode at all :-(
Other people have reported being able to scan bar codes dislayed on a Tungsten screen.   Sorry, but I don't have one to test on.

Download ZIP file with .prc and NSBasic source: Version 1.5   6 November 2003.  

Version 1.5 changes the narrow/wide bar ratio for more reliable scanning of the printed screen capture and has a Demo button (if you can't think of any text to bar code).
Version 1.3 corrects intercharacter spacing for specific character combinations.
IRTest screen IRTest is a very simple IR communications program.   It uses no protocol and does not check for transmission errors.   It allows you to send and receive messages between m68k-based Palms (III, V, etc).   It may not work on the newer Palms (Tungsten) with the OMAP processor because of differences in how the devices handle IR.   If you would like to donate an OS5 device for testing, I would be most appreciative, and would be happy to give you credit on this page.

WordFone screen WordFone converts those "vanity" phone numbers such as 1-800-hilton1 into the numeric equivalent.   It accepts "-" or "." if you want to use a group separator and will also work without separators.

Download ZIP file with .prc and NSBasic source: Version 0.2   1 October 2004  
Want to experiment an NSBasic screen capture/display program? This is primarily for the OS5 devices with fast processors - waiting 6 minutes for a screen capture on an m125 isn't for most people. This is a proof-of-concept program - it does not capture the Palm color palette, so the captured screens are displayed with the current device's default colors. There's also a PC program to display the captured screens.

Download ZIP file with .prc and NSBasic source: Version 0.5.5   31 May 2004.  
Want to compute the Heat Index for the conditions at your location?   HeatIndex will calculate the HI value for temperatures of 80 degrees (F) and above and for humidity values of 10% and above.

Download ZIP file with .prc, NSBasic source, and the NOAA reference for computing HI: Version 1.0   14 Aug 2007.  
Screen captures are done using the Palm OS Emulator with OS 4.1 and the Palm OS 5.1 or 5.3 Simulator.   "Live" testing is done on a Palm Zire with OS 4.1, Palm M125 with OS 4.0.1, a Palm IIIxe with OS 4.1, a Palm V with OS 3.5.3, a Symbol SPT1500 scanner with OS 3.0.2r3 and a Zire 31 with OS 5.2.   More to come when I have time to play ;-)
