Most of my projects are pragmatic tools written to replace bloated software, cloud-first wanky-ness and tools that actively get in the way of doing actual work.
They exist because I needed them, used them and just got sick of subscribtion "professional" software being worse than what I can do myself or costing an arm and a leg to do basic functions.
- Ash's MEP Playground – Genuinely one of my favourite things I've built. Drag-and-drop P&ID diagrams, then simulate real hydraulics through the system (Darcy-Weisbach losses, pump curves, operating points). Now with a full electrical discipline too: draw the single-line diagram and it generates a hierarchical schedule of loads, a cable schedule with voltage-drop and ampacity checks, an electrical BOM, and one-click auto-sizing. When you're done, package the whole lot into clean ISO engineering drawings with the analysis and full bill of materials. Local, offline, no licence server, no login.
- Modbus RTU Tester – Debug Modbus devices locally without vendor software, serial terminal archaeology, or blind faith.
- Construction Cost Calculator – Construction cost calculator for engineers who prefer arithmetic and logic over optimism and don’t enjoy being gaslit by spreadsheets.
- Cable Tray Calculator – Calculate cable tray fill, weights, and sanity without spreadsheets, guesswork, or site arguments that start with “it should be fine”.
- Engineering Drawing Maker – Turn images and PDFs into proper ISO-style engineering drawings without AutoCAD, SolidWorks, licence servers, or a multinational claiming custody of your own work.
- OBJ Viewer – Preview OBJs, bake lighting, and render clean turntable animations to MP4 or GIF. No cloud, no accounts, no Blender pilgrimage.
- STL to OBJ Converter – A local STL → OBJ converter with batch drag-and-drop, vertex welding, mesh cleanup, and basic transforms. No cloud, no accounts, no Autodesk
- Video Converter – FFmpeg GUI for converting videos without memorising flags or naming files
final_v7_REAL_THIS_ONE.mp4. - Image Converter – Convert images between formats, resize them sensibly, and generate ICO files without opening Photoshop or questioning your life choices.
- PDF Manipulator – Merge and split PDFs without Adobe, Java, subscriptions, or spiritual compromise.
- Free to use, available to everyone
- Local-first
- No cloud dependencies
- No subscriptions
- No telemetry
- EXEs included where it makes sense
- Source always available
If you want to help out the projects and update, bugfix etc please feel free to send pull requests. I do have a day job so apologies if it takes me a while to get round to reviewing and merging your code. Will give full credits in the ReadMe to anyone who makes my code less janky!
