How to Launch a Weather Balloon. DIY – How to launch a weather balloon into space. This video shows a family effort in launching a balloon into the stratosphere, 17 miles up. The balloon carries a camera and an iPhone, which acts as a tracking device to aid recovery: If you would like to send up a balloon of your own, this month’s issue of Make magazine has a nice article on the topic: Weather Balloon Space Probes They recommend getting a balloon from kaymont.com (the 1,500g sounding balloon). Get a radar reflector from Davis Instruments (this helps keep airplanes from crashing into your balloon). Get parachutes from the-rocketman.com. In the video, they used a foam cooler with some handwarmers to keep things warm. If you want to be official: FAA stuff. Near Space Photography. BALLOON PART NO: HAB-350 (350 gram) ----IN- STOCK!!!

ROCKETMAN PARACHUTE DECENT RATES These calculations will help you to predict the speed at which your rocket will descend with Rocketman Parachutes.
Note that it is only an estimate, and values will vary with wind, different air pressures, Diameter, length of rocket, fin size, etc. Payload Rocketman's Payload Recovery Parachute Unmanned Ballon Stratosphere On June 21 I launched a 1,200g weather balloon to 93,757 feet. April 19, 2012: Last month, when the sun unleashed the most intense radiation storm since 2003, peppering satellites with charged particles and igniting strong auroras around both poles, a group of high school students in Bishop, California, knew just what to do. They launched a rubber chicken. A Rocketman High Altitude Balloon Payload Recovery Chute was used in the recovery of the payload from this launch. ...Click below for the whole story. Beam me up, Kitty. SD/MicroSD Memory Card (4 GB SDHC) ID: 102 - $11.95. Misc. Boat - Final Assembly.
With the Base-Station recently completed I moved on to the final assembly of the POCV itself. The recently spray-painted hull. The wood supports and brackets also got a spray of protective varnish. The rear two batteries and the motor with ESC. The CMPS10 is mounted at the front, inside a small up-turned box. The rest of the batteries & the rudder servo.
Camera and Stop-Start switch. The servo arm for the rudder came with an allen key grub screw. The Kort nozzle & propeller. Universal Joint between the propshaft & motor. The electronics. The wires for the umbilical. The socket for the POCV. installed. Finished. The obvious next step was to plug the POCV into the Base-Station. Wired up to the Base-Station. Turning on the power, and well, it didn't work. After a bit of faffing around I have decided I will remake the umbilical. If anyone else happens to be thinking of using an umbilical, don't. Combo - Raspberry Pi + 3G modem + GPS module = endless fun « milos.ivanovic.blog. So… I bought a Raspberry Pi. It was really tasty, so I had to buy 300 more. Ok, so it’s not actually raspberry-flavoured and it certainly has nothing to do with pies, or the mathematical constant π either.
What it is related to, however, is electronics. In a nutshell, it’s: an ARM-based, fully-featured, embedded computer scaled down to the size of a credit cardit has a 700MHz stock-clocked ARM CPU (ARM1176JZF-S), and 256MB RAMan SD card slot to store the operating systemHDMI + composite out100mbit LANa GPU fast enough to play full HD 1080p video2 USB 2.0 portssome low-level peripheralsand it costs just $35USD What a neat little thing. You can read more about it and its initiative at the Raspberry Pi Foundation’s website. Mine actually arrived about a month ago but I never found the time to sit down and blog about it – well, now I can!
My Raspberry Pi, with a 3G modem and GPS module connected, all running off a 16Ah battery. Documentation - 3G + GPS shield for Raspberry Pi tutorial. The new 3G shield for Raspberry Pi enables the connectivity to high speed WCDMA and HSPA cellular networks in order to make possible the creation of the next level of worldwide interactivity projects inside the new "Internet of Things" era. The module counts also with an internal GPS what enables the location of the device outdoors and indoors combining standard NMEA frames with mobile cell ID triangulation using both assisted-mobile (A-GPS) and mobile-based (S-GPS) modes. Other interesting accessories which can be connected to the module are a video camera which enables the record of video in high resolution (640x480), an audio kit including microphone, speaker, hands free and headphones sets and a SD socket to save directly all the data coming from the 3G network or recorded from the video camera.
You can even reproduce audio files stored in the SD card (almost and mp3 player!). With the SD Card socket so you can handle a complete FAT16 file systems and store up to 32GB of information. Documentation - 3G + GPS shield for Raspberry Pi tutorial. Hardware - How do I attach a GPS receiver? - Raspberry Pi Beta - Stack Exchange. GPS Receiver I would go for a generic usb GPS receiver such as the BU-353 It works with the Raspberry Pi, just like a normal linux computer. Most usb GPS receivers are just USB-to-Serial adapters that read the NMEA data from the GPS receiver. Look into pl2303 (many units i've seen use this particular chip) drivers, should be available. You can also use GPIO and a traditional NMEA 0183 GPS receiver, but then you need to worry about power, and the prices are often higher.
The usb solution is cheaper. Software The gps receiver I mentioned is compatible with gpsd. sudo apt-get install gpsd gpsd-clients python-gps This will install gpsd and related software. NTP Clock To synchronize the clock with NTP, you need to install ntp. sudo apt-get install ntp. Getting GPS to work on a Raspberry PI « Peter Mount's Blog. One of the tasks I want to use a Raspberry PI for is to take over the duties of an existing ITX based linux box running my weather station. Now in theory that should be pretty simple as the current setup uses pywws to connect to the station and as that’s written in python it should work. Now the Raspberry PI has no onboard Real time clock – which means it needs to use an NTP server to get the time when it starts. Usually you would use the default settings and allow the PI to connect to thenet for it’s time. Now this is fine if you have a working net connection but what if you are not connected to the net?
You might be in the field running the PI on batteries. As the other projects I have lined up for it is to connect my Meade LX200GPS telescope to the local network or to work with my (in prototype) radio telescopes so having an accurate clock is going to be required. Now the obvious solution here is to use GPS as a time source. The hardware Plug it in and run lsusb Now restart ntp:
