I don't see a clear cut answer...will this work on a seperate PI?

Greetings I have a pi, with a GPS hat on it connected to a USB 3G modem. I'm wondering if anyone can suggest a case (doesnt have to be a pi case as i dont need access to the monitor,and other ports and only need one usb) where somehow my usb modemm can be on the inside? since I don't want it to get ...

Normal users cannot write to /var/log. sudo runs after shell redirections are set up, so it is too late to help with >/var/log/myError.log. If your program really needs root privilege then put it in root's crontab using "sudo crontab -e". Otherwise drop the sudo and put the log file somew...

Thanks for your assistance however, I'm having a little trouble understanding what you are reffering to, my linux jagon isnt up to par.

Logs I write to are showing up blank, system logs have no errors, and the cron reboot doesnt run no matter how simple it is or what ever combination I try.
Have you gotten a reboot working on your pi? cause im seeing other people having these issues.

no spaces in the #! line in your script - output to a file /tmp/log or something to see if it works it may be that it is running too soon and something else is not initiated [network ??] put more debugging in your scripts or use systemd and restart it after the system is up I think i debunked the t...

What I am trying to accomplish Good day all. I am working on a project where when I my PI sends GPS coordinates received to a webservice. If the PI is rebooted, a cron runs and calls my python script to start the gpsd service and start sending my coordinates to my server again. What I have done so ...

if you need a simpler gps unit, there is a gps hat by adafruit with full tutorials. https://learn.adafruit.com/adafruit-ultimate-gps-hat-for-raspberry-pi/overview its low power and supports an external arial how well does it work indoors? it's exactly what I want but if it's cant work indoors or in...

I would go with the GlobalSat. You might also be interested in the Earth Mate by Delorme the GPS LT20. It is similar to the GlobalSat... is a very small package, high sensitivity, takes its power from the usb, and has a cable that gets the receiver up away from the rest of your gear for good recept...

Greetings I am trying to construct a product where I can track my PI remotely. I will be able to power my PI with the 5v 2amp that it needs, however what I am trying to do is find a GPS unit that can draw it's power directly from the Pi and I wont have to somehow get a second power for the GPS unit....

Seems perfect,
Just hope GPSd will work with this device (will be wiring it to USB)

I have purchased this GPS device GPS Receiver - GP-735 (56 Channel) along with another device needed to connect to is VIA USB.

Good day While looking for the smallest possible GPS solution for a Raspberry PI 2 searching has brought me to these solutions. - https://www.sparkfun.com/products/13670 - https://www.sparkfun.com/products/11818 I am thinking of getting those two, but being more of a programmer than an hardware pers...

Well What I am attempting is to make my own pet tracker. Using a Raspberry Pi, with a 3G usb and a powersource. Ill then be able to log into my web and look for said device plotted on the map. So I can search by pet name / device name. Yes this can be done...log your data from GPS into a web and us...

Both GPS and 3G-Modem can come as a USB-device or as a "add-on" board that can talk "serial" or "spi" or "i2c". The simplest are usually a USB solution ( IMHO ). There also exists a few 3G-Modems that also contain a GPS. You are absolutely right topguy. Sugge...

100-150. Thanks, well I will try with just the 3G modem see how that goes, and work to adding GPS unto it.
Thanks for the talk.

Do you have any resources that will assist me in this venture? tutorials you may have written, tips and the like?
