Cat / Dog Detector
This can be used to control entry on a Cat or Dog Door. NOTE: There may be some changes and improvements coming. However, this circuit does work and you can build it as shown. The PCB shown below is available...
The Technology of the Tube Screamer
The Tube Screamer series of distortion and overdrive pedals from Ibanez has gained a legendary status in the music community, particularly due to the endorsement of Stevie Ray Vaughan. The TS-808 and TS-9 models are highly coveted and often traded...
Low energy consumption audio signal generator
On occasions when it is necessary to determine if an amplifier is functioning, the most effective tool is an acoustic signal source with a frequency around 1 kHz. The specifications can be considered flexible, as rapid tests typically do not...
DC biasing audio signal
The audio source will be a line-level audio signal ranging from -2V to +2V AC, which will be passed through a 220µF coupling capacitor followed by a two-pole low-pass filter (RC). The signal will be processed by an Analog-to-Digital Converter...
Detector switch circuits
A simple test circuit designed for troubleshooting audio and radio equipment. It can inject a square wave signal rich in harmonics or be used with headphones as an audio tracer. A single-pole double-throw switch is utilized to toggle between injection...
Fuzz Face
This is simple almost beyond belief for distortion devices. Two transistors, four resistors, three capacitors, and two controls make all that tone. The first transistor is set up with the simplest of arrangements - input through a DC blocking capacitor...
Detector And Controller
Many applications require analog signals to be sensed and digital signals to be controlled. A way to detect these points is by using a 555 timer in an unconventional configuration. This method will also add hysteresis to the circuit and...
Cook Your Own Distortion
In the late 1960s, the first distortion effect boxes were developed to replicate the sound of razored cones and overdriven amplifiers. Today, most amplifiers feature a distortion control, yet distortion effects remain popular. This discussion will focus on the methods...
Audio signal control circuit
Audio signal control circuit. It illustrates a typical audio signal control circuit where two audio signals enter the integrated circuit through switching and tone controls (treble and bass), subsequently adjusting the output sent to the audio power amplifier.
The audio signal...
