We decided to buy a cool rugged military spec cellphone because we need something with a good camera that will survive thermal shock, and bumps when it lands. We got it off ebay for only $43 -- makes Dad happy too!

We visited the kaymont.com website to learn about our choices for balloons.
The MIT team used a 350g balloon from this supplier, but recommended a larger ballon. The website recommends this balloon: BALLOON PART NO.: HAB-800 (800 gram) These balloons are recommended for individuals or groups who have had experience in HAB launches and are primarily using payloads of 2 to 4 lbs (1000 to 2000 grams). Balloons are normally inflated so that there is an ascent rate* of approximately 270-300 meters/min (890 to 1000 feet/min), which results in typical bursting altitudes of 90,000 to 100,000 feet. We think we will use this balloon since it will go up really fast with a light payload (less driving to find the balloon, less chance of things freezing, less chance of batteries running out), and will burst at a super high altitude. The downside of a larger balloon is that it will cost more, and require more helium to fill it ($). We will research helium next. The Kaymont website also has some cool project links we will check out later. http://kaymontballoons.com/Project_pages.html We are already working on an idea to take some near space photos. We have been inspired by a couple of MIT students who sent a weather balloon into space with a cellphone and camera to take photos. They got to 93,000 feet altitude before the balloon burst, and took some amazing photos. Luckily the photos were on a fast exposure to reduce blur!
The team posted a how-to guide that we will be studying so we can assemble our supplies and do some testing. http://space.1337arts.com/ You can see a photo of a near-space weather balloon on our ABOUT page. As we figure out what to buy, and we conduct our pre-launch testing, we will post progress reports here. Hey, welcome to our Blog.
This is a blog about all of our exotic successes and disasters (mainly disasters) while trying to have fun building some pretty cool stuff. We are planning to make several projects over the next few months, and we will post the results along with some pictures here. Maybe even video... ! Most of these are projects that other people have done, and that we thought were pretty cool. We are always looking for cool ideas of things to build on the cheap, so make sure you let us know your coolest project ideas (and cheapest.. Dad). |
