One might tend to marvel at the wide sophisticated range of talents we have across the continent. From cars created to cleanable pillows, Mobile phones to ATMs, you may begin to garner some sense of hopefulness for Africa.
Arnold Caulker is a young and prospective innovator and electrician who placed his wits to the test by creating an inverter generator and amplifier from the ground up. Sounds unbelievable, right? Let’s get into the proper details!
Arnold Caulker hails from the Eastern part of Freetown in a community called Kissi. He developed a deeper interest in innovation at a very tender age. Though discouraged by close associates to sought for other alternatives, Arnold was keen on pursuing his dream of being an innovator. The diploma student at Milton Margai University is also an electrician. With his earnings, he is able to ply through electrical component shops for supplies to aid his startup innovations. The young prodigy was able to create an Amplifier and an Inverter Generator from scratch.
THE AMPLIFIER
Arnold’s first project was the Amplifier. The project started in 2020 and was completed on the 10th of December 2020.
The Amplifier works with a dry cell battery. An outlet is reserved to connect your phone which can be used to play audio recordings. The actual board implanted in the device was solely created by Arnold according to what he prefers. The amplifier is fully functional, operable, and simple to use.
THE INVERTER GENERATOR
The Inverter Generator is the landmark exploits of Arnold Caulker. The project began in 2020 and finished up on June 24th, 2021. Within that period, the work was established and managed by Arnold.
Inverter Generators are portable machines that can be used to power appliances and other devices. Arnold’s brand of machine is no different. Though it is temporarily used with car batteries, the device is rightfully operated by Deep Cycle Batteries. It can also use solar power.
The circuit, when switched on, automatically navigates power and transfers it to the device. It can power refrigerators, electric irons, bulbs, fans, and all other additional housing appliances including Air conditioners. Other features include short circuit protection, reverse voltage protection, overload protection, overvoltage protection, and under-voltage protection. It produces high and constant power. The device can put any appliance on.
All the boards used in all of the devices created were made from scratch. The printed project boards were designed with components from electrical and electronics shops. They were also set up based on the wishes of Arnold.
I am a young innovator by the name called Arnold Caulker.
Arnold told The African Dream
I developed passion for innovation from when I was at the age of seven, despite there was no support.
I keep developing that passion and now I can be able to think about something draw it and work on it and there will be a result in real life.
So in that case I can manage to make some of my illusion become reality, because I have passion for what I am doing.
