Martymic Talking Micrometer for a Blind EngineerFollow project
Martyn contacted me through Remap (https://www.remap.org.uk/) and is an engineer who builds competition go-cart engines. Advanced visual impairment means that reading precision measuring equipment is now impossible for him, so I set out to solve the problem.
The solution is the combination of a Bluetooth enabled digital micrometer, available for industrial users who log measurements for quality purposes to PCs etc, and a single board computer called a Raspberry Pi Zero.
This mini-marvel supports Bluetooth and has been programmed in Python to receive the measurements from the micrometer and using a freely available TTS (Text to Speach) engine, and a small audio amp and speaker, read out the measurement.
Martyn previously had to get other people to make precision measurements of his engines, but now he can make them himself.
