Practical Calculators for Motorsport Electrical & Harness Engineers

Working with a bunch of tools? We can't help you with that, but we can provide a growing set of free, browser-based calculators built around real-world E/E design problems. No installs, no sign-ups, no spreadsheets to maintain. Each one is self-contained and runs straight from your browser, on the bench or at your desk.

These came out of our own day-to-day work in F1 and Formula E electrical design. We built them to save ourselves time, and we're sharing them in case they save you some too.

Available now:

• E/E Toolkit: Wire current capacity with staged derating, voltage drop over distance, and splice / multi-term CSA sizing

• Bundle Sizer: Pack wires into a bundle and see the overall diameter, with a clear visual and a colour-coded gauge key. Built for CAD engineers working to representative bundle sizes, and for buying the right sleeving ahead of build

Spotted something that'd be useful for you or your team? Get in touch - we're always happy to build tools around real engineering constraints.
