Car Door Close Optimizer Circuit
In this post I have explained and tries to solve a common car door opening issue which may be seen in quite a few old model cars. The proposed circuit of a car door close optimizer was requested by Mr. Mark Rothwell. Technical Specifications Just stumbled across your site, hope you can help/advise me?I have […]
Vehicle Speed Limit Alarm Circuit
In our previous articles we have learned comprehensively regarding the ICs LM2907/LM2917 which are fundamentally frequency to voltage converter ICs, and are ideally applicable in all such relevant fields. Here we see how the same chip can be applied for making a vehicle speed limit alarm circuit. Using a Single IC for Speed Detection As […]
Multi-spark CDI Circuit
In this post I have explained an enhanced multi-spark CDI circuit which is universally suited for all types of automobiles. The unit can be built at home and installed in a particular vehicle for achieving greater speed to fuel efficiency. The Circuit Concept The following diagram illustrates an enhanced version of a multi-spark CDI circuit. […]
Motorcycle Regulator, Rectifier Tester Circuit
The motorcycle regulator, rectifier tester circuit presented here can be used to test a 6-wire shunt type regulator-rectifiers for a 3-phase charging system of motorcycles. These reg./rectifiers (RR-units) are usually sealed with epoxy and it is considered difficult to find out if the unit is faulty or not. Designed and Written by: Abu-Hafss As the […]
