About TechCalcs
Practical calculation tools, right when you need them.
A Calculation Tool Service for Mechatronics Engineers
Mission
TechCalcs is an engineering calculation tool service for quickly and accurately performing the technical calculations that come up repeatedly in mechatronics (mechanical, electrical, and electronic) fields.
We aim to provide calculations that are "not quite worth pulling out a textbook for, but tedious to look up every time" in a ready-to-use form whenever you need them. Beyond just producing numbers, we visualize results with animations and diagrams so you can intuitively understand "why you get that value."
Features of TechCalcs
Visualization You Can "See and Understand"
Rather than simply returning answers, we use animations and diagrams to help you intuitively grasp the meaning of calculation results. We focus on helping engineers develop a feel for the physical meaning behind the numbers.
Just the Right Level of Detail
We prioritize focusing on the calculations you actually need, rather than adding features for the sake of it. Coming from outside the professional domain gives us a unique perspective on designing tools that are neither too complex nor too simplified.
Commitment to Calculation Accuracy
All calculation formulas are implemented based on fundamental physics principles and practical standards (JIS, ISO, etc.). Reference formulas and derivation sources are documented within each tool for transparency. Calculation results are reference values only; we recommend consulting specialists for critical design decisions.
Target Users
TechCalcs is designed for all engineers and makers working in the mechatronics field.
- Mechanical / Manufacturing Engineers (Design, Production Engineering, Maintenance)
Gear ratios, torque, cutting speed, spring constants, etc. - Electrical / Electronic Circuit Engineers
Ohm's law, LED resistor values, voltage drop, etc. - Hobbyists in Electronics and Mechanical Work
Scooter and motorcycle maintenance, Arduino and Raspberry Pi projects, etc.
Available Tools
We continuously expand our tools across the following categories that make up mechatronics.
| Category | Example Tools |
|---|---|
| Mechanical Engineering / Power | Displacement, gear ratios, torque/RPM conversion, cutting speed, spring constants, etc. |
| Machining / Fabrication | Milling fz, milling vf |
| Electrical / Electronic | Ohm's law, LED resistor values, voltage drop, RC time constant, etc. |
Future Plans
We are broadening our coverage into calculation areas needed in the field but not yet available as tools, such as thermodynamics and fluid mechanics, to more comprehensively cover each area of mechatronics. We also aim to enrich the calculation formula explanations for each tool, making them useful for engineering education as well.

By profession, I'm a web engineer with experience in system development across a wide range of industries including food, retail, real estate, automotive, beauty, e-commerce, and payment systems. I studied physics in university, and through hobbies like scooter bore-ups and engine swaps, electronics projects with Arduino and Raspberry Pi, and building DIY effects pedals, I've regularly encountered situations where mechanical and electrical calculations are needed.
TechCalcs started from wanting to solve that inconvenience. Coming from outside the professional domain, I try to design each tool at just the right level of detail—neither too complex nor too simplified. I prioritize focusing on the calculations you actually need in real situations.
