Car Tank Water Sensor Circuit
In this article I have explained a simple car tank water sensor alarm circuit using IC 555 and a pulsating signal on the sensing probes to pevent corrosion on the probes. The idea was requested by Mr. Peter. Circuit Objectives and Requirements I couldn’t find how to post a project proposal on your website. May […]
Understanding Motorcycle Voltage Regulator Wiring
The article provides a detailed explanation regarding the various voltage regulator wiring configurations used in motorcycles. The article was submitted by Mr. Abu-Hafss. Technical Specifications After working on different voltage regulators, I feel to share my findings on your blog so that other people may also get benefit. Please insert the diagrams appropriately in the […]
10 LED Tachometer Circuit
In this post I have explained how an accurate 10 LED tachometer circuit can be built using ordinary parts like IC 555 and IC LM3915. The idea was requested by Mr. Munsif. What is a Tachometer A tachometer is a device which is used for measuring vehicle engine RPM. Thus, it is basically used for […]
Bluetooth Car Ignition Lock Circuit – Keyless Car Protection
This circuit will allow the user to lock his car ignition using his phone Bluetooth, meaning the ignition can be locked/unlocked only through a specific code from the user’s cellphone Bluetooth. Overview In one of my earlier posts I have already explained how to hack a Bluetooth headset and use it for any desired switching […]
Motorcycle Accident Alarm Circuit
In this post I have explained how to make an useful motorcycle accident alarm circuit for sending alarm signal to the distant population in an event of an accident, especially if it happens in a relatively lonely area. The idea was requested by Mr. Rayan D’souza. Circuit Objectives and Requirements I want a circuit that […]
