We build software, run our own servers and keep history rolling. Every project starts as a small splash.
No agency, no sales pitch. A handful of people who like to tinker, each with their own corner: code, servers, 3D printers, and olive-drab vehicles from the 1940s. These are the projects we actively work on.
3D design for printing, laser cutting & CNC
Draw a flat face, pull it into a solid. Volura brings the SketchUp way of working to makers: push/pull modelling, multicolour 3MF for the printer, SVG and DXF for the laser cutter, and a check that every part is watertight before it leaves the screen. For Windows and Linux.
WW2 vehicle rides past care homes
Convoys of restored Second World War vehicles that ride past care homes, bringing the sound and smell of 1944 to the people who remember it. History lives. Memories remain.
A full cinema experience on one PC
Films from Jellyfin, Plex, network shares, USB or DVD and Blu-ray on the projector, with a separate control screen for the operator. Subtitles in the right language, a "now showing" card on extra screens, and a Linux kiosk image that updates itself.
Virtual cameras for any NVR
Turns plain RTSP streams into virtual ONVIF cameras, each with its own MAC address and its own IP from DHCP. To an NVR like UniFi Protect they look like real devices. Optional object detection for cameras that have no brains of their own.
Bringing a server front panel back to life
An Unraid plugin that drives the Axiomtek AX93304: a 2×16 character LCD with four buttons on an old serial port. It cycles through system info and gives the buttons a small menu to start or stop the array, reboot or shut down.
Everything on this page runs on hardware we own and look after ourselves. The deeper you go, the more interesting it gets.
Eight Raspberry Pi 5 boards with NVMe storage, shared over GlusterFS and managed with Komodo. It hosts this site, the Rollendrespect site and a long list of home services.
Servers, storage and workstations talk at ten gigabit. Moving a film, a disk image or a model checkpoint takes seconds instead of a coffee break.
Several virtualisation hosts run virtual machines and containers side by side. A test server or a fresh experiment is a few clicks away, and nothing important depends on a single box.
Servers at several locations, linked together, plus a few cloud services for the things that must never go down. Every connection has a fallback, all the way down to satellite internet. If one line or site goes dark, the rest keeps swimming.
Most of the hardware runs entirely on solar power we generate and store ourselves, with our own emergency power behind it. When the grid drops, the pond keeps glowing.
We run our own OpenCode services on self-hosted models of around 125 billion parameters. Coding agents that help build projects like these, without our code or data leaving the building.
HOLLANDPOEL is not one person. It's a small group that shares tools, servers and too many cables. Some of us write code, some of us restore and drive old army vehicles, and most of us own at least one 3D printer.
Tools we needed ourselves, shared with everyone.
From a sketch on Volura to a part on the desk.
Pi clusters, 10 Gbit networks and servers at more than one site.
Keeping 80-year-old engines and their stories running.
Popcorn, a projector and software we wrote for it.
