Keyboard shortcut for “Mirror Displays” on Touchbar MacBook

It’s kind of a niche requirement but very important for someone like me who runs presentations with keynote split on two screens to running demos that need to be mirrored. It was always Cmd-F1 on any non-touchbar equipped Mac, but sadly that stopped working on the new Macs, even if you hit the fn key […]

Upgrading a node module that wraps C code

Today I wanted to get this ultra-thin LED matrix working with Raspberry Pi in NodeJS as part of my work on my new ST4i workshop. The SeeedStudio Ultrathin Red LED matrix. It’s such a nice bright matrix, I really love it, but they’re a little weird to work with. They use the HUB75 protocol which […]

Review of 2015 – the year of electronics

2015 has gone by in a blur – at first I couldn’t remember the details of what I did. There have been so many different threads and distractions that it occasionally felt like I didn’t accomplish much. But now I’ve looked back at my calendar I’ve realised that there was actually a lot going on. […]
