Share My Creation Freon: Freeze On Neck personal cooler !

Hi all

Here is Freon : Freeze On Neck personal cooler!

While we are still in summer times, here in France, I wanted to try something like the Sony ReonPro .
But it was way too expensive... so I made mine !
Of course not as "smart" but smart however as powered by B4A !

1. choose between manual and automatic modes
2. set the Freon power (manual) or the target temperature (auto mode)

That's it, you can close your app unless you want to monitor the sensors and see how efficient are the two PIDs controlling the temperature.

Everything is open source open hardware and described on hackadays pages

If you like this project please leave a like on hackaday it could help to (possibly) win the 1Hz challenge !

Source code firmware and B4A app on my github


And a first video to show you what is inside freon :

cheers
