I build small apps and tools when I need them and can’t find them anywhere. Some are useful to exactly one person — me. Some might be useful to you too. They run entirely in your browser, no installs, no accounts, no nonsense. I’ll keep adding to this as I build more.
Fusion 360 measures sketch angles from the left side of the baseline — so when you need a mirrored line at the same angle, the number you type isn’t the same number you drew. This tool does that one calculation instantly. Type your angle, get the one Fusion wants.
Physical Nixie clocks are expensive and fragile — so when you want that vintage warmth on your desktop, standard digital displays look flat and lifeless. This simulator renders authentic cold-cathode tubes instantly, complete with stacked wire filaments, independent ionization flickers, and dynamic under-glow. Customize your colors, get the analog look.
