Cheap GPS receiver

gps

Here’s a short guide for converting a Palm III GPS sled into a normal serial GPS receiver. The Palm III is old tech so its accessories can be picked up cheap and modified for other purposes. The GPS receiver needs to be separated from the Palm specific board and a few components need to be transfered between the two. Once that’s done you should have a standard serial GPS receiver. Here’s a cache in case the “Read” link fails.

    Here is an even simpler way to modify a Palm Streetfinder GPS. No need to even crack open the case.

    I’m all for hacking… but I bought a brand new USB gps for $40 on ebay, win/lin compatible and works perfectly for me.

    I had a palm III streetfinder gps and it was awful. It took forever to get a lock and actually figure out its position.

    anyone got a hack out there for making the gps that comes with msft streets and trips ’05 mac compatible? thought i was going to get another dell for college, but the rents surprised me

  7. telloc says:

    I did this hack about a year ago. I used a USB cable to power the board, and put the resulting mess in an altoids can, soldering the antenna to the top. Good stuff!

  8. nevarmore says:

    I learned a LOT about the nature of GPS while toying with this.

    For compatibility look for devices that are NMEA 0183 compliant. The data coming out of those is just a raw string of numeric data that all mapping software should (had damn well better) be able to parse out.

    Interesting, in the UK PCWorld says they can sell you a palm iii with this gps on it, for the grand price of 97p. Unfortunatly its “temporarily out of stock”.

  10. pimpybra says:

    I actually tried doing this before, but not separating the two boards… You can just hook directly up to the serial tx/rx leads on the connection to the palm, and then still use the power AC Adaptor.

    However, the circuitry must have been rather sensitive to the soldering heat, since after I soldered two small leads, the entire thing died. :(

    Does anyone know if the Handspring ‘Magellan GPS Companion’ module can be hacked in this way? – I’ve got one lying in a drawer which I used to use with a long since dead Handspring Visor. It would be neat to make a GPS module out of it which I could use with my laptop. If anyone has any links etc, I’d appreciate a mail to iridium_sunrise@hotmail.com
    cheers

    I have MapSource (Middle East V2 Map), and a normal Serial (PCMCIA) GPS Module in my laptop. Problem is that when i start the Tracking, all the details of Maps are locked, a message on the bottom right corner shows ” Map Details Locked”, what does that mean? and how can i unlock it. I have already unlocked the maps with the key but i don’t understand how to solve this problem.
    I don’t want to contact Garmin cause i am not using Garmin GPS Module.
    So any suggestion or advice?
    Only reason why i am using Garmin Map Source is that they have Middle East detailed maps.
    Thanks in advance.

  14. does anyone know how to get a good GPS system up and running in thier cart? The Magellan 300 GPS systems are closing out as low as the high 300 dollars on E Bay. I am interested in purchasing one. However, I don

    Is there any way to interface this stuff with a Dell Axim X5?

    Dear Hackers
    You guys seem to know a lot more about GPS than I do.

    I having been searching for quite awhile for an inexpensive GPS system that can be put into automobiles. The system doesn’t have to be fancy it only has to find the location of a car when needed.

    Does anyone know of such a system?
    If so, do you know how much it cost ? and
    Where do I get GPS tracking software

    Thank you in advance

    frits i have followed your instructions for the hack for v7 metroguide,but i keep getting error saying that i cannot name key with in it.any help would be great.

    That’s because you have to make subfolders/keys:
    for instance HKEY_LOCAL_MACHINESSOFTWAREGarmin is an existing key than make new key by clicking right mouse key give it name mpasource, click on it make new key name it families etc etc.

    I purchased a segway and it came with a etrex legend C and north american maps V7 city select…..

    I can send you the maps and my unlock codes if this will help you. or copy/swap the disk.

    Im new to this and have not tried much as the maps are useless to me. Only unlocked for myself out of curiosity.

    Cheers

    Hi

    I can generate unlockcodes for your GPS and MapSource.

    Will you please send an email to:

    gps@pinodyr.com

    With information about:

    – UNITID for your GPS (not SERIAL) – MapSource can extract this UNITID from your GPS.
    – Which Mapsourceproduct AND version you want an unlockcode for (i.e. City Select Europe v7)

    And I will generate a testcode for you.

    Cheers
    Ruder Papgaard
