ParttoGo Tools is an open-source collection of practical calculators for industrial automation work — including PLC raw counts, analog signal scaling, voltage drop, PSU sizing, motor loads, and field wiring basics. Built for engineers, technicians, and makers who want fast, transparent calculations without digging through scattered spreadsheets or manuals.

Hey Product Hunt 👋 I’m launching ParttoGo Tools today — an open-source collection of practical calculators for industrial automation work. I started building this because many everyday engineering checks still live in scattered spreadsheets, manuals, forum posts, or vendor-specific tools. For simple tasks like scaling a 4–20mA signal, converting PLC raw counts, estimating voltage drop, sizing a 24VDC power supply, or checking motor load references, the workflow often feels more fragmented than it should be. ParttoGo Tools is designed to be: ⚙️ Practical — focused on real automation and field engineering use cases 🔍 Transparent — formulas and assumptions are visible 🧩 Open-source — easy to inspect, improve, and extend 🚀 Fast — no login, no vendor lock-in, just quick engineering utilities Current tools include calculators for PLC raw counts, analog signal scaling, voltage drop, PSU sizing, motor FLA, overload references, and more. The project is still early, and I’d love feedback from engineers, technicians, makers, and anyone working with industrial systems. What calculators should we add next? What would make this more useful for real maintenance, wiring, commissioning, or sourcing workflows? Thanks for checking it out!

honestly this looks super useful, i've been juggling way too many spreadsheets for scaling and voltage drop. one thing that would help me out a lot is letting users save their last few inputs or common setups so you don't have to retype values every time you open it. would save real time on the bench.

Congrats on launching ParttoGo | Industrial Tool! Open-source calculators for automation engineers is a genuinely exciting direction. Cheering you on and wishing you a fantastic launch! 🚀
