Things I made because I wanted to know how.
I'm Daniel. I tune scientific instruments for a living and, at home, rebuild 3D printers, write small programs, run a basement full of servers and keep a garden. This is where I write down what I made, what broke, and how I fixed it.
Printers
MrMakeIt
An Ender 5 Plus with nothing original left but the power supply. CoreXY, Kalico, 350 mm.
Micron+
Desk-sized Voron descendant from a West3D kit. The printer I actually reach for.
Ender 3
A stock Ender 3 rebuilt piece by piece: Klipper, a direct-drive toolhead of my own design, linear rails on X and half of Z.
Taz Pro 6
A LulzBot Taz Pro with two print heads, rescued from work, still stock and still misbehaving. Headed for new extruders, 1.75 mm filament and Klipper.
Homelab & electronics
Homelab
Two Proxmox nodes, TrueNAS, cameras, and a team of agents that watches it all overnight.
Ceiling fan bridge
An ESP32-C6 and a CC1101 radio that send and hear the fan remotes' codes, so the fans are Home Assistant entities.
LinkyLink
An Android app that bridges my phone's notifications, alarms, reminders and to-do list to my own servers, and lets Claude talk back.
Energy monitor
A sixteen-channel panel monitor running community ESPHome firmware instead of Emporia's cloud, with eleven named circuits.
SolidWorks keypad
A small USB macro pad on an ESP32-C3 for the SolidWorks shortcuts I hit a hundred times a day.
Bench power supply
An ATmega328-based controller for a benchtop power supply: three monitored channels, two seven-segment readouts, a 20×4 LCD and an encoder.
