If you perform analog-circuit design, you'll occasionally need to use a resistor with a nonstandard value to produce a particular gain, ratio, or attenuation factor. You can create resistors of ...

Bought to my attention by programming luminary Andy Cordani, was something he spotted here at Hackaday, which is a very nice application of multiplexing and matrix maths to determine the value of ...

Many times, the need arises to interface single-supply analog-to-digital converters (ADCs) and comparators to real-world signals like 5 V. Of course, it's possible to condition the signal using ...

This is a handy resistor colour code “calculator” that doesn’t need power supply or to be installed on a PC. As you know most resistors use coloured bands in order to show their value. So basically ...
