| Here we present a direct-reading audio spectrometer using a microcontroller, a graphic equalizer chip, and not much more. Using seven vertic...
| Analog circuits have had their day; everything is digital now. Here we present a simple digital amplifier built with standard CMOS logic gat...
| Sometimes the need arises to construct a really simple oscillator. This could hardly be simpler than the circuit shown here, which uses just...
| This circuit has been designed to complement the ‘Simple IR Transmitter’ and to decode its transmitted signals. The similarity to the transm...
| This circuit uses just two standard logic ICs which, with the accompanying receiver, forms a four-channel remote control and has been design...
| The TDA1572 integrated AM receiver circuit performs all the active functions and part of the filtering required of an AM radio receiver. It...
| The clock in computers and many other electronic systems is normally provided by a simple crystal oscillator. Unfortunately, the electrome...
| Here is a very easy and inexpensive way of building a crystal oscillator from a Single lC. Only two of the inverters contained in the IC...
| The Type 555 chip must be one of the most popular ICs used in electronics. Here it is used as a vco (voltage controlled oscillator). The...
