Online technical calculator

While browsing through newsgroup sci.engr.electrical.compliance last night, I came upon a posting for an online engineering calculator. At www.calculatoredge.com, you’ll find calculators for numerous engineering fields such as electrical, electronics, physics, mechanical engineering, and chemical engineering. In the electrical, electronics, and physics sections, the site provides calculators and circuit diagrams for filters (Butterworth, Chebyshev, and others), bridges, antennas, attenuators, and many others. The next time you need a quick calculation, give this site a try.
