[foam box, apply duct tape to hold shut] (https://www.grainger.com/product/12F276?gclid=CjwKCAiAwZTuBRAYEiwAcr67OYmFsxWbQPsZ6q6G2LcJL5M4zB0FDx7diAlZz8JqX1lQ9P6GeFZPjBoCnbAQAvD_BwE&cm_mmc=PPC:+Google+PLA&ef_id=CjwKCAiAwZTuBRAYEiwAcr67OYmFsxWbQPsZ6q6G2LcJL5M4zB0FDx7diAlZz8JqX1lQ9P6GeFZPjBoCnbAQAvD_BwE:G:s&s_kwcid=AL!2966!3!50916733197!!!g!82129239837!)

just a thing to hold your electronics in to keep them insulated from the cold during flight, and cushioned for the impact of landing.

[piezo electric buzzer, attach to arduino to give an audible alarm to help track down your payload after landing] (https://www.adafruit.com/product/1536?gclid=CjwKCAiAwZTuBRAYEiwAcr67OVsUCcFPwRh9nBWLsDKDr9_VNEnteEJxQoZ5P8Z_j0ddqz6boPAyfRoCeLkQAvD_BwE)

not required but can be helpful when hunting down your payload

[hand warmer] (https://smile.amazon.com/HotHands-Hand-Warmers-Odorless-Activated/dp/B0007ZF4OA?sa-no-redirect=1)

also optional, i've never used them, generally used to keep your batteries warmer as warm batteries perform better than cold.

[GPS Antenna] (https://store.uputronics.com/index.php?route=product/product&product_id=72&search=gps)

gotta get GPS signals somehow, i highly suggest the MAX M8Qs from Ublox

[AA battery packs, i suggest using the energizer ultimate lithium batteries] (https://www.digikey.com/products/en/battery-products/battery-holders-clips-contacts/86?k=battery+holder&k=&pkeyword=battery+holder&sv=0&pv91=355996&sf=0&FV=-8%7C86%2C32%7C306832%2C1989%7C0&quantity=&ColumnSort=0&page=1&pageSize=25)

you'll likely use a 4-6 pack that has the batteries connected in serial to supply the 5v the arduino needs

[trackuino shield and guide] (http://hab.education/pages/trackuino.html)

this tells you where your payload is via sites like aprs.fi

[cheap external temperature sensor] (https://www.digikey.com/product-detail/en/maxim-integrated/DS18B20/DS18B20-ND/956983)

the trackuino code already has provisions for this temp sensor so it requires very little modification to the code to use.

[antenna, no coat hangar required] (https://www.byonics.com/antennas)

Any antenna thats made to operate on 144.390 mhz (assuming you are in the US, other countries you'll have to check your band plan) will work. I make mine from 2 19" pieces of 20 gauge wire.

GoPro settings that we have used on past launches, such as the one here - https://www.youtube.com/watch?v=-qNUDRwAlL0

(Note: we've done video using our GoPro Session, with other cameras taking still pictures):

  1. Resolution: 1080
  2. FPS: 60
  3. FOV: Wide
  4. Low Light: Auto
  5. Spot Meter (OFF)
  6. Protune (OFF)
  7. Orientation: Auto (Up/Down)

    Explanation of some of the above:
    3 - Caution when selecting Wide or Ultra Wide; per John Flaig's HAB photography guide, when using Wide or Ultra Wide "the horizon can appear to bend and bounce whenever the camera moves".
    4 - This allows the camera (when at 48fps or above) to reduce the frame rate in low light conditions to achieve optimal exposure. We were OK sacrificing frame rate for better exposure with the variation of light that we expect to experience.
    5 - Similar to if you put the GoPro inside of your car but wanted to have the exposure tuned to outside your windshield, select this if you can see the payload insulation at all around the edges of your camera frame to be sure it focuses on the lighting outside your box. We had this disabled since no payload was in our field of view.
    6 - You can post-process to apply the Protune edits using GoPro studio after the fact, if you decide that you want to.
    7 - We also prefer to set the correct orientation prior to the launch, instead of leaving it up to the accelerometer in the GoPro, so there is one less thing that can change on us during launch preparation. The orientation is locked once you start recording, so if you remember to hit "Record" when upright, this will prevent any need to edit in GoPro studio after the fact. We prefer to set it (correctly) and not have to worry about edits.

    Charging: Also, remember that the GoPro can record while charging. We use this external battery booster (5400mAh) with a USB splitter cable to charge all our devices (GoPros, tracking cell phone) while in-flight: https://www.amazon.com/gp/product/B00LVFFQ9S/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Sorry to keep bothering you, but would this work?

https://www.amazon.com/BaoFeng-UV-5R-Dual-Radio-Black/dp/B007H4VT7A?keywords=baofeng&qid=1539145631&sr=8-4&ref=sr_1_4

Includes receiving of 144Mhz. And is there somewhere that has a tutorial on how set it up to listen to my callsign?
