Take a picture, from 30km up!

high altitude ballooning has been around for a long time.

only until recently, people have started to put a digital camera, and mcu-programmed timer so that the camera will snap pictures as the balloon goes up to 100,000ft or more - the record for manned flight is about 100,000ft (30km), achieved by the USAF way back and not ever since duplicated.

here are some stories about high altitude ballooning.

some breath taking pictures.

the favored cameras are Canon (especially the A-series) because they can be reprogrammed. check out the Canon Hack Development Kit.

to recover the camera, you will need to have a gps module on the camera to send back its coordinates so you can picture up the camera.

fascinating stories.

好像是说拿一个探空气球放到平流层里面拍的吧,那个相机真厉害,那么冷竟然没有冻坏

好像哪个国家一群中学生和他们的指导老师做过这个项目，相机是用保温材料保护的，并且用微控制器控制；他们用冰箱做过实验，很严谨。

相机居然能回收，真神奇。气球能控制降落的精确位置难道？
这技术真是想想都复杂，外国佬实战能力很彪悍。
anyway，没有相关的电路资料？

GPS+GSM应该可以发回座标。
