Networks · automation · open source
A home for practical tools, connected technology and the lessons learned while building them.
About
I’m Will, a solutions engineer with nearly two decades of experience across networking, infrastructure and connected systems.
The Tech Shed is where I turn real problems into useful software, experiment with new ideas and publish enough detail for someone else to build on the work.
Recent work
Five current projects spanning connected vehicles, desktop tools, live data and network testing.
TypeScript · Python · Connected EV
Coming soonA private, read-only dashboard that turns MyŠkoda vehicle data into a clear view of battery, charging, efficiency, journey history and vehicle status.
Python · Desktop & CLI
Generate validated QR codes for links, Wi-Fi, contacts, events, SMS and more—with a desktop preview, image export and a capable command-line interface.
Python · WeatherLink
A modern dashboard for Davis WeatherLink stations, bringing live observations, gauges, a wind compass and selectable history graphs into one clear interface.
HTML · TfL data
Live Tube and Elizabeth line status dashboards for browsers, wall displays and DAKboard—with responsive layouts and configurable widgets.

A syslog traffic studio for generating, receiving and investigating logs—now being rebuilt as a native SwiftUI app for macOS.
Browser tools
Practical utilities that run entirely in your browser—no account, uploads or tracking required.
Turn an IPv4 address and CIDR prefix into its network range, mask, broadcast address and usable hosts.
Open calculator →Create a scannable Wi-Fi code locally, without sending your network name or password anywhere.
Create a QR code →Turn host requirements into a right-sized, non-overlapping IPv4 addressing plan.
Plan a network →Create validated A, AAAA, CNAME, MX, TXT and SRV records in zone-file format.
Build DNS records →Find the registered hardware vendor for a MAC address or OUI through the MACVendors database.
Look up a vendor →Inspect public DNS records, TTL values and DNSSEC status through Cloudflare’s 1.1.1.1 resolver.
Run a DNS query →Project notes
Enyaq Pulse
Coming soonHow a responsive dashboard, a local Python collector and resilient SQLite history turn MyŠkoda data into a clearer view of an Enyaq.
Website update
Introducing a new collection of practical browser tools, beginning with an IPv4 subnet calculator and Wi-Fi QR generator.
QR Generator
Building a validated QR code tool that works equally well from a desktop window or a terminal.
