I Put a Neural Network in a Thermometer — Then It Got Out of Hand

TL;DR · WeSearch summary

Alex Rosito shares his journey of integrating a neural network into a thermometer. Initially a simple project, it evolved into a tool called Hasaki that trains and exports neural networks as standalone C headers. This innovation allows for AI inference on microcontrollers not originally designed for such tasks.

Key facts

▪Rosito began by building a basic thermometer using a thermistor and microcontroller.
▪He later replaced the polynomial correction function with a neural network, successfully running it on an ATtiny85 microcontroller.
▪Hasaki, the tool he developed, trains fully-connected feedforward networks and exports them without dependencies.

I told her to check her phone. She gave me a look and said, "No — in here. In the apartment." The next day I remembered we had a clock with a built-in thermometer somewhere. Found it, put batteries in it, problem solved.
