Make cool projects raspberry pie It is usually the whole meaning of having one.Single board computer 40 GPIO pins The seemingly endless number of external sensors, buttons, etc. can be connected, but the manufacturer Mcllrn has decided that this is no longer necessary. Mcllrn only uses the CPU itself, trying to turn the processor into a function button, you can use it for input in any Python program.
Add this to the list of actions we can perform with Raspberry Pi but you probably shouldn’t. In the spirit of pushing Pi to its limits, we must highlight this project because it is one of the smartest uses of CPUs we have seen so far.
The “press” button is recorded by continuously monitoring the temperature of the CPU. When Mcllrn touches the processor with his bare fingers, the temperature rises. This temperature change is sufficient to detect and record a specific response. A simple Python script demonstrates input recognition in the demo video shared by Mcllrn.
some The best Raspberry Pi project These are the ones you can recreate at home, but you may want to slow down before you start poking the processor. What is impressive is that things like CPUs can be used in ways that deviate from their original purpose. However, this setting is far from optimal in actual settings. Continuous use may damage the processor, especially when considering risks such as static electricity.
