If you are tired making the same boring calculation over and over again, find here an on-line sophisticated calculator for your electronic circuits.
For example, suppose you have a batch of resistors that you do not know the value. You must then calculate it from it's color code. Not very hard but absolutely boring. Use the on-line resistor color code calculator from Dr. Calculus and it will do the job for you! Or do you have some transistors that you have to supply using a voltage divider? You can always use the voltage divider calculator from Dr. Calculus and in a few seconds you will have the resistor values that you need!

    Just added: 555 calculator as astable oscillator
   Just added: Op-Amps inverting amplifier calculator


Our gigantic circuits archive is growing fast

It is yet considered one of the biggest circuit portals over the net. Visit it to get some awesome ideas for your designs, get some ready-made solutions for your circuits or just hop around the net to see what other people or companies are making and of course how they do it. Because of our HUGE library, we have make categories for you to browse and thus make your life even easier.


Today we have include 10660 schematics!   
Last update was on 6/3/2008 		 


  Read and participate in our theory pages!

Do not forget to visit all of our theory pages! Find the links on the left side menus. Extended theory analysis for many-many electronic matters that you may be interested of. If you need theory for something that we do not have yet cover, you can always ask it using our contact form. Also, if you write theory yourself and you want to post it on the net, we offer you the space to do it. We will be happy to have your theory pages hosted on our servers. Get in contact with us (always using the contact form that we provide) and start now!
