I usually perform the majority of my coding or design on either my late 2012 Mac mini or 2019 iPad Pro. I also use a 2017 Microsoft Surface Pro. I use a variety of mechanical keyboards, including Magicforce 68 and an Anne Pro 2. I’m in the process of restoring an IBM/Lexmark Model M2 and converting it to USB. Mice are generally plain ‘ol Microsoft ones.
For soldering its a TS-100 with custom firmware.
3d Printing is handled by my Ender 3 Pro with an upgraded BigTreeTech mainboard and Display, and a few other modifications to keep it running sweet. No big hotted changes yet however!
