A series of videos showing how CE Manufacturing makes their capacitors on original equipment.
Type in a value of capacitance and convert quickly between mF, uF, nF and pF.
Ever wonder how equivalent capacitance is calculated from a set of capacitors wired together? Confused by other non-visual calculators? This interactive program allows you to build out your own capacitor wiring diagram and calculate the equivalent capacitance for the circuit.
A video with helpful information on how to easily prototype circuits using breadboards, padboards, and stripboards.
Wiring diagrams for some of the most popular electric guitars including: Tele, Strat, Les Paul, PRS, ES-335 and SG. Note: each wiring diagram is shown with a treble bleed modification (a 220K resistor in parallel with a 470pF cap) added to the volume pots.
Passive low-pass and high-pass filters are found in a multitude of circuits including the tone knob on a guitar, the tone stack in amplifiers, and tone controls in pedals. This hands-onn interactive demonstration will show you how these filters work on actual audio output.
This drawing of an imaginary guitar points out the names of common electric guitar parts.
Learn about guitar speaker power handling to help choose a speaker to last a lifetime.
A quick comparison of current production Jensen guitar speakers including sound samples and technical specs.
This calculator helps determine the correct resistor for use when powering a single LED. You will need to know the forward voltage and forward current which are usually located in the datasheet for your LED. With those two numbers as well as your supply voltage you'll be ready to calculate the current limiting resistor value.
This program will provide you with a visual guide on how to wire your LEDs together (ncluding proper resistor values) to obtain proper function based on your input voltage and the number of LEDs you are wiring.
Confused about how op amps work? For those without a fancy workbench setup for testing op amps, this virtual oscilloscope and wave generator will allow you to build and test your own op amp circuits to see how they affect voltage gain. Useful for determining how to wire an op amp to obtain the gain you need in your circuit, as well as for learning how op amps work!
Learn how to identify the value of capacitance for your orange drop cap based on the cryptic codes like 223K.
Resistance vs. shaft rotation plots for some common potentiometer tapers.
There are multiple types of potentiometers out there. If you are confused about what the difference is between linear, audio, reverse audio, and logarithmic potentiometers, this guide will provide you with the information you need to determine which type of potentiometer is appropriate for your application. In addition to why they might be used, an interactive demonstration will allow you to see how resistances change in a circuit depending on the rotation of your potentiometer.
Learn how to identify the value of resistance for 4 band and 5 band color code resistors.
Ever wonder how equivalent resistance is calculated from a set of resistors wired together? Confused by other non-visual calculators? This interactive program allows you to build out your own resistor wiring diagram and calculate the equivalent resistance for the circuit.
