Will try those as well :)

Thanks so much!

Good idea. I'll try that out.

I'll try that out. Getting the pots out of the molds is always the trickiest part.

Awesome tips. I'll try those out!

SPOT GPS

Hey. Super cool tutorial. I'm looking to use a GSM module to relay data from the ocean back to us onshore. I'm searching for the module you have and am having some trouble finding it. Could you link the website to which you purchased it below.

Cool! Sounds like a similar process.

The regulator can only handle about 800mA. I'd refer to your motor datasheet. It may work for your small motors dependent on the load and speed you intend to run them. There's other voltage regulators that can handle more amperage. I would recommend one of those.

What's the question? Happy to help.

Awesome to see you are working on the project. I have been receiving quite a few emails lately regarding this exact issue. RahilV2 built the data logger and was able to solve the problem. Here is what he did:I have fixed the initial error and it was because the .INO uses the old gps port name which is 'gpsPort' instead of 'gps_port'. The preprocessor symbol has also changed. All the example programs now use 'GPS_PORT_NAME' instead of 'USING_GPS_PORT'.It seems all you will need to do is change the names of a few values as Rahil explains above. Hope that helps!

We attach SPOT GPS units to the package which track and transmit the coordinates back to us.

I just sent you a private message, hope it helps!

Location for retrieval is done with a SPOT GPS unit working separately from the Arduino data logger.

Awesome! Thanks for the support. We got super lucky with the clear skies on that day, check out my Ultimate Data Logger to see some really cool pictures of Pacific Beach, Mission Bay, and the famous Crystal Pier!

Is the tracker transmitting the data from the GPS breakout board? If so, having both data logger and transmitter should not be a problem as long as they don't interfere with timing, power consumption, or use duplicate hardware pins. Likely you should be successful! Wish you luck.

Hey Benjamin, thanks for the support! I haven't used an electronic heating pad but I would assume it would work. This would mean your system is pulling more energy. The flight described above uses a 9 volt battery and logged for over 4 hours. This is when I unplugged the system, it could've run longer. I have since switched to AA batteries for most flights. They do add weight but provide higher capacity and a voltage typically more suitable for external sensors (CO2). I would assume either 9 volt or 4x(AA) would work just fine for your flight. Just ensure you are not using alkaline batteries as these will freeze. Hope this helps!Aaron

Awesome to hear you are doing this project! In step 2 of this Instructable I share both the connections written out and a Fritzing schematic thing. I can try and see if I have a physical schematic if the Fritzing and written out connections don't suffice. If you have any other questions, please reach out.

Ensure you have the softwareSerial library and NeoGPS library downloaded.

The GPS unit is picking up signal from satellites orbiting the planet. The GPS sends the NMEA sentences to the Arduino which then decodes them. All of the info is stored on an onboard microSD card. This unit is not communicating with the ground. Good luck and I hope this helps.

If the flight is cleared with the FAA and a radar reflector is attached to the payload, you are all good!
