Building the Rim 900 Mobitex modem

Matthias Wandel (https://www.youtube.com/@matthiaswandel) is an engineer, woodworker, and YouTuber who runs the most-viewed woodworking channel on YouTube. He was an early employee at Research In Motion, assigned employee number 13. Yacine (https://x.com/yacineMTB) is an engineer building autonomous drones. Both of them are tinkerers, explorers, and builders in their own right. They poke at the world, build and test things for themselves, and develop their own understanding.

In this conversation, we traced a single thread through Matthias’s entire life: what happens when you grow up in a place where the only way to have something is to make it yourself, and then never stop. We started in Northern Ontario, in his dad’s workshop on a gravel road where the nearest store was an hour away, and followed that instinct through his first encounters with computers, a Bic-pen dot matrix printer on a Commodore 64, two brothers with two machines in a basement heated by a wood stove, lock picking in the Waterloo service tunnels, and what it means to be a nerd.

Matthias and Yacine went back and forth on simplicity vs. ease, what LLMs change about the relationship between understanding and building, and why the probability of code getting reused is inverse to the effort you spend making it reusable. Matthias walked through building the DigiSync barcode reader for the motion picture industry, writing almost all the firmware for RIM’s first wireless modem in DSP assembly, watching BlackBerry’s network traffic flip on 9/11, and what it was like to work alongside Mike Lazaridis. He explained why he left BlackBerry while sales were at their peak and how a bandwidth constraint accidentally made his first viral YouTube video.

This is a conversation about constraints that become capability, capability that becomes independence, and independence that becomes something you pass on.
