In this installment, we start developing a simple design by testing parts that satisfy a design. Along the way we demonstrate the use of a few types of digital interfaces that many sensors use, though there are many more out there. The sensors you use will depend on what experiment you're trying to do, basic recording of a flight, some experiment trigger at a particular altitude, and live video transmission would have different requirements from each other. Each one still usually has a strict weight limit, so efficiency is a must.
Next time, we put the pieces together and test it, and compare it to data from a real flight to see if these parts would do a good job.

In this video we will cover the common tools used for developing simple electronics for high altitude weather balloons. This is meant to be a basic overview of each tool and we will go into more detail into some of these tools later on.

In this video, we have a simplified third person look at how a launch works along with checking out some bits of footage from real launches. Next time, we'll dive into tools commonly used for development and some tools that I personally use to make things a little less of a headache. Then we'll get into how one of these payloads can be designed and built.
