Smart Watch Lobotomy - DevConf

Taking a cheap smart watch and making it do what I want.

Talk given at DevConf Cape Town & Pretoria - 23 & 25 May 2023 on hacking a cheap smart watch.


This talk is a continuation and update of my previous talk as I finally got everything to work.

The talk covered all of the BLE hacking and reverse engineering the hardware and dumping the watch firmware and reverse engineering it in Ghidra.

The very long blog post that covers everything only half of what I spoke about and more is available here with more to come soon.

Slides are available here

Original Abstract

Taking the cheapest smart watch on Takealot, completely reverse engineering it and building new software for it adding the features I want.

Find out how to dump firmware, identify components, decode buses and make things blink while destroying only a few watches.

This talk is filled with hardware hacking, reverse engineering, a little embedded software and a lot of googling and at the end of it all I might still have a watch that tells the time with working bluetooth.
