The Intergovernmental Panel on Climate Change just released a draft summary of a report to the UN. Unsurprisingly, the panel concluded both that the Earth’s warming is unequivocal but now expressed near certainty that human activity is the cause of the observed and predicted climate shifts.

Given the near universality of scientific opinion on climate change, I’ve begun to wonder what motivates climate change deniers.

I’m working on launching a high-altitude balloon later this year with a Raspberry Pi serving as its flight computer. The Raspberry Pi is an excellent tool because it allows you to do most common tasks at a higher level of abstraction than other MCU platforms. However, it lacks at least one of the major conveniences of MCU’s like the AVR that I’m accustomed to working with - the analog-to-digital converter (ADC). In this article, I’ll describe one solution to the missing ADC, albeit a little complex. For this project, I’m using an ATTinyx61 to serve as the ADC, communicating with the RPi as a slave on the I2C bus.
