hi! this is malachi. just saying FYI this is a complete break off of the balloon thing. anyway... this is a text based adventure i made with python. its not done yet... its like 99.999999% done so yeah. things to do: *make it possible to kill king kong. *make it end the programm when you beat the game :P *potato. *make it simpler to move. so yeah. if you guys would like to try it out, heres the files (download all four then go to your download directory and double click "eddies_castle.exe"):
so yeah. one last thing... to move you do: west, north, east, south.

we got a All New Battery Bank just in case... Our phone already has 1850mAh. (milli amp hours is a measure of battery size) the bank has 6600mAh so its got more than 3 times the phone battery. we weighed it and it weighed 174g and the phone weighed 161g. so it basically doubled the weight. so its ok as long as it weighs under 2000g. the bank said that it can only work above 32F which is freezing. we expect to get as cold as -60F at very high altitudes. because it will be cold it wont give all the juice to the phone but luckly its lithium which is the best type of battery at low temp. it was at five below (the store) for five bucks. -Ezra
hi! this is Malachi. recently we got the phone we were using to track the balloon and where it lands. and honestly i don't think we can get anything better then this. we use a GPS to track where it lands and it was not that good at first because we could not see where we were (and by that i mean us... the car... not the balloon). but we figured out that we could turn the cords to google maps and it was wayyyyyy better.
tracking = "done" we activated our phone by using a sim card from target for 10$ (and using consumer cellular) (no IDW with MLA) We got our phone in the mail today! We also found a Great website for what we need: Phone Tracking! we are really happy we found what we need. It is called Real TIme GPS Tracker, and it is free on Android (it might be also available in the app store!). We also liked it because it was very customizeable and easy-to-use. ![]() <--- Ezra with the phone with the GPS tracker running We used the tracker to send the location of the Android phone, and it worked! We were able to see the location of the Android phone on a second device. We set it up to wake up GPS every 10 minutes to save batteries. Here is a picture of the screen:
Hey this is Ezra. We have found an interesting website. It is interesting because it predicts the path of the balloon and where it lands. You have to put in a starting place on a map, and tell it the time of launch, and how fast the balloon will rise. You also have to put in how high the balloon will be when it bursts, and how fast it falls. We tried it from our house tonight at 9:30pm, and the balloon was supposed to travel 195 km (120 miles!!!) in 4 hours. It was predicted to land in London in Canada! Here is a screenshot: We plan to use the website when we launch our mission. We will need to make good guesses on the information it needs. It will be helpful to make sure we don't go in a lake or into Canada!
The website address is : http://predict.habhub.org/ Check it out! We went to the Rocketman Online website today after googling parachutes. Wow! these guys make chutes for exactly our kind of mission.
We liked the look of the 3ft chute because anything larger would descend too slowly with a 1-2lb payload -- the wind would catch it more and make it go further away. The 3ft chute with a 1.7 lb payload descends at 11 mph. That means if our balloon goes up 100k feet or 20 miles, it will take 2 hours to get back down! WHoa! The team cut and pasted the wrong balloon -- we think this is the best one so far, because w expect our payload to be quite light.
BALLOON PART NO: HAB-600 (600 gram) These balloons are recommended for individuals or groups who are launching a photographic payload for the first time. Package payload should be 1-2 lbs (500 to 1000 grams).The balloon size will provide effective training in how to prepare a package for launch, give some experience in filling a balloon, tying the neck properly, learning connection lengths between balloon and parachute and between parachute and payload, then gaining practice on some of the procedures for successful launches. Although the size is ideal for training purposes, if successful the package should reach a burst altitude of 75,000 to 90,000 feet. |
