A float switch is a device which detects a fluid level (such as water) and activates a set of contacts which may be further integrated to a control circuit for restricting the fluid flow behavior. Why a Float Switch The advantage of a float switch is that it works without a direct contact with the […]
Newly Updated Circuit Projects:
Testing Alternator Current using Dummy Load
In this post I have explained a method of checking or verifying alternator maximum current delivering capacity using a shunt regulator as the dummy load and an ammeter. The idea was inquired by Mr. Joe. Circuit Question I need help designing an electronic dummy load that can handle high enough power from motorcycle alternator. I […]
Make this Insect Wing Signal Detector Circuit
In this article I have explained a VLF receiver circuit used for detecting insect wing beat signals, the idea was investigated and built by Mr. Steven Chiverton. Insect Wing Triggered ELF An incredibly fascinating electrical outcome successfully identified with the VLF are wing sounds triggered when bugs like bees, flies, and mosquitoes fly within a […]
Submersible Pump Start/Stop Circuit
In this post I have explained an automatic submersible pump start, stop circuit with dry run protection in order to implement an automatic ON/OFF switching of the motor in response to the high/low water levels of the overhead tank. Circuit Concept In one of the previous posts I have explained a similar concept which also […]
Delay based Motor Speed Controller Circuit – Timer Controlled
In this post I have explained a delay OFF adjustable motor controller circuit so that the motor can be assigned a fixed predetermined operating time, or delay OFF time. The idea was requested by Mr. Cribey Technical Specifications I really like your website. It is very helpful for so many people. I am trying to […]
