Top free DIY tools every EE needs

-May 21, 2014

Every electrical engineer who does DIY projects knows that dozens of free resistor calculators are out there that can save quite a bit of tedious work. Other simple tools can be found, but traditionally the free tool arsenal would stop there. Sure, there are base platforms such as SolidWorks and Autodesk, but what happens when they are missing a feature needed at that exact moment?

Now we're seeing a relative explosion in free tools for engineering electronics. It is easy just to hit the Net and use the myriad resources available. Some of those online tools prove to be worthless, and it's back to blind searching or some paid tool, but free software extends far beyond the functionality of a simple calculator.

To help sort out the nonsense from the useful online tools, check out the following list.

Calculatoredge: when one calculator isn't enough


Calculator choices from Calculatoredge.

One of the more useful tools in an engineer's toolbox is a physical calculator. Why does it seem to get lost when it's truly needed? Workstations usually save the day. Those included in your OS of choice (Windows, iOS, Linux, etc.) are good for simple tasks but not so great for other things, even in scientific mode.

Searching for the right one online will net you roughly 131 million choices. Which one are you to choose when there are so many? Why not choose them all?

Almost all calculator versions known to humankind are located in one convenient site, Calculatoredge. It boasts no fewer than a few hundred calculators for just about every field imaginable (and perhaps some that are unimaginable), including electrical, mechanical, civil, chemical, and even math. There's no need to search aimlessly for that obscure number cruncher ever again. Some of the more complex calculators even come with some rudimentary instructions.
