About Us

Hi, I am Vaibhav. I am not a professional software developer by training. I am an engineer who learned to code because the tools I needed were either missing, buried behind paywalls, or simply unpleasant to use. That gap between what I needed on the shop floor and what I could find online is the real origin story of this website.

On a normal working day I might need a quick pneumatic cylinder force, a gear ratio for a conveyor redesign, a GD&T true position check, or a sheet metal bend allowance before releasing a drawing. Each time I searched, the same pattern appeared. I would land on a page loaded with distractions, or a tool that demanded an account before showing a result, or a calculator that broke on mobile when I was standing next to a machine. It was frustrating enough that I stopped searching and started building.

In February 2026 I published the first version of TaskJunction with a single pneumatic calculator and a unit converter. The response from colleagues and students told me the problem was not personal. Engineers everywhere wanted the same thing: clean pages, correct formulas, and instant answers without ceremony.

One calculator became five, then twenty, then more than sixty. Each new tool came from a real question I had faced or a problem someone messaged me about. I do not publish a calculator because a keyword looks good in search results. I publish it because an engineer somewhere will need that exact calculation tomorrow morning, and they should not have to fight a website to get it.

Most of the tools on TaskJunction are ones I use myself. When I size a clamp for a welding fixture, check a safety factor on a bracket, or confirm a tap drill size before a trial run, these pages are where I go. That personal use is my quality check. If a calculator is awkward or wrong, I find out quickly because I rely on it in my own work.

TaskJunction will keep growing. New calculators are added regularly based on community suggestions, comments on social media, and problems I see in industry. If you have an idea for a tool that would save you time, write to me. Some of the best pages on this site started as a single email from a student or a shift engineer who said, "I wish there was a calculator for this."

If a tool here helps you once, that is enough reason for me to keep building.

Vaibhav Dhokpande, Creator of TaskJunction

Today TaskJunction offers more than 65 free mechanical engineering calculators covering fluid power, drives and power transmission, structural elements, sheet metal and stamping, machining and CNC, fixture and tooling, GD&T and metrology, thermal and fluid systems, and emerging areas like EV battery sizing and renewable energy estimates.

Beyond calculators, you will find a career guide for students mapping paths through JEE, diploma routes, and PSU opportunities, reference charts like drill and tap sizes, and everyday utilities such as unit converters and scientific calculators. Everything is designed to load fast, read clearly on a phone, and work without creating an account.

Every page includes enough context for you to understand what the formula assumes and where it applies. We are building reference quality tools, not black boxes that spit out numbers without explanation. When you share a result with a colleague or paste it into a calculation sheet, you should know what you are looking at.
