analog vocoder
This is the initial Instructable and the first attempt at a large electronics project. The circuit has been designed from scratch and is being made available.
The presented project involves the design of an electronic circuit that has been developed independently....
Suitable comparator circuit headset detection
A headphone type detection circuit is illustrated in the attached figure. The 2.2k RMIC-BIAS resistor connected to the audio controller provides a low-noise reference voltage (VMIC-REF). When the audio jack is inserted, the VMIC-REF voltage through RMIC-BIAS is applied to...
Analog Mains Frequency Meter
Mains frequency is pretty stable and it is unlikely that you have to measure it but if you have an emergency generator you might find this circuit useful as it will give an indication whether the generator is running too...
Constantly changing light and sound analog controller circuit 04
Constantly changing light and sound analog controller circuit 04
The circuit designated as the "Constantly Changing Light and Sound Analog Controller Circuit 04" is designed to modulate both light and sound outputs in a dynamic manner. This type of circuit...
The reference voltage of the symmetrical bipolar comparator
An AI comparator input is connected to a reference resistor (Rl). When the output reaches a specified level, known as VREP (absolute value), the output also stabilizes at this level. The outputs Ai and As are connected to an OR...
Analog Tachometer Readout
The analog display consists of a frequency/voltage converter (IC12) and bar-graph segment drivers IC10 and IC11. More: R34 is the calibration adjustment and is set so that an engine rpm of 5 000 to 7000 rpm lights the first LED...
Four-channel-comparator
When operated as an open loop without compensation, the HA-2400 functions as a comparator with four selectable input channels. The clamping network at the compensation pin limits the output voltage, enabling DTL or TTL digital circuits to be driven with...
Comparator with time out
The MC1422 functions as a comparator with the input at Pin 5. The frequency of the output pulses, dependent on the values of R2 and C1 as indicated, is approximately 2 Hz, with a pulse width of 0 ms at...
Analog Voltage Camera-Image Tracker
By utilizing a low-cost RS-170 camera and this circuit, a voltage that indicates the position of an object within the camera's field of view is generated. IC2A and IC2B create a valid video gate that keeps IC3 in a reset...
