Electronic Selector Driven by Relays

The circuit was aimed to produce an electronic selector for ten alternative sources with the means of showing the result in a 7-segment display being driven by relays.

Switch Control with Touch-Sensitive Input

The objective of the circuit is to create touch switch control that is sensitive enough to detect the input to perform the desired output.

Relay Switch Activated by Tone and Signal

The essence of the circuit is for the input of tone and signal to provide an activation for the relay switch.

Gain and Volume Adjustment for Balance Input

The circuit was designed to create a balance input device that would provide an adjustment of gain and volume while having a symmetrical electronic input.

Light Sensitive and Differential Temperature Switch

The circuits were designed to illustrate the functions of two switches with the use of a single op-amp to show the operations of a precision light sensitive switch and a differential switch.

Auto Timer Circuit with Extensive Limit by LM555

The circuit was designed to produce a timing scheme that will provide a longer span of time to become activated.
