Most people want something that is according to their needs. In other words we want stuff that suits our own preference.
In the last couple of days I was busy innovating the power supply I am using for my projects and circuits. This is why some of my time for writing was consumed for this project. I have always mentioned in my previous posts that aside from writing, I am also a hobbyist and electronics enthusiast.
Warning: Electricity can kill!
What is a power supply?
I am not going to lecture about electronics for this post so you need not worry. I am just going to share a bit of information about power supply. You can always use the internet for your own research.
In electricity and electronics, a power supply is an electrical device that supplies power to an electrical load. It is sometimes referred to as converters, adaptors or commonly known for your electronic gadgets and devices as chargers. A battery can be a power supply too but its energy is limited.
Note that the electrical voltages that supply our electronic gadgets like cell phones and other home appliances are using only 12VDC, 9VDC 6VDC and or 5VDC. You must understand that our home electrical outlet 220VAC is converted to lower voltage from AC to DC by this power supply so that it is suitable for devices that need a small amount of power voltage.
As a hobbyist, power supply is a main tool for me. There is a lot of usage of this kind of device in electronics. For example I am using a 12VDC for my Mini rotary tools. I also use a power supply to test bulbs and LEDs even if I have a multi-tester with me.
Sometimes if I am fixing home devices that need only 110VAC of power I need to borrow a power converter from a friend. In PH we use 220VAC in homes and offices as a source of electrical power that is why most home appliances and devices here are made for 220VAC power.
I also need to use a 220VAC switch controller in some of my projects so I have to use a separate power supply too.
This seems to be a problem to me and I wanted an all in one power supply for my projects. I know there is a suitable power supply for electronic hobbyists but this is kind of costly so I just made a power supply. A personalized one that can be useful for my projects.
DIY Personalize Power Supply
The main idea is to have a 12VDC Variable power supply, 110VAC source and 220VAC controller in one enclosure. This design is only for my personal use because that is kind of an issue when it comes to using this three in one project.
Variable power supply
This type of power supply is useful to me because it has the ability to set the output voltage from 1.5 to 12VDC depending on the need supply of the load. The picture above is a regulator circuit I have made to adjust the desired output voltage.
110VAC Source
Below is a 3 Amps transformer with a center tap. Meaning I can use the center tap for 110VAC appliances. So I will no longer have to worry about borrowing a power converter from my friend.
220VAC Controller
This device is useful and it has the same capability as the Variable power supply. The only difference is that the variable power supply is DC and can control lower voltages only while 220VAC Controller is AC and controls voltage up to 220VAC.
I just finished the project and it may not be beautiful to look at. Most of the components I used are recycled. The 3Amp transformer is from an old Karaoke sound system. The enclosure is from a broken air pressure pump. The switches, AC outlets and knobs are salvage components from electronic devices.
Below is the finished product. By the way I have added a 5VDC supply for my portable mini soldering iron. So to wrap it up I have a 12VDC Variable Power Supply, 220VAC Controller, 110VAC (fix output supply) and 5VDC (fix output supply) in one box.
