A question about Flyback Tester

Hello again mr Humphrey, i just wanted to ask you a few questions concerning the flyback tester, where exactly does one have to start when assembling it DIY?

Do it yourself Flyback Tester

As a technician there are test equipment that one requires to get started in electronics which are assumed to be obvious in order to get started in your repair work may it be for hobbyist or professional purposes.

Among them they are others which are not taken seriously as a starter kit but as you walk down the road you find it necessary to add them on your work bench.

When this need arises the technician has an option to go shopping for one or decide to do it by him or herself.

I would like to address the latter group which decides to do it themselves. Although most people would prefer to go this route, you realize that very few people can access the printed circuit board facility around them and hence become difficult for them to get started.

In this article I am going to show you how you can go round this problem by using readily available vero board and achieve the same result like the machine printed circuit board.

As a starter kit (D.I.Y) I have done a template using strip board of the flyback tester based on circuit diagram found on the internet and its working wonderfully for me.

Component values are recorded on their body. Resistors, capacitor, ics , transistors etc for ceramic capacitors the number is written on the body. For ics I advice to use ic sockets instead of soldering them directly to the circuit board.

Testing Degausing Coil-Only 3 LEDs ON.

What is this simple tester capable of doing:-

1. Testing primary winding of flyback transformer in circuit.

2. Testing horizontal yoke coil in crt television /monitors.

3. Testing primary winding of switch mode power supply(all) in circuit

4. Testing the degaussing coil winding in crt television/monitor

5. Testing small DVD motors like the spindle motor ie 2 led lights.

Challenges: as you can see i had a problem of getting a good housing for my project, electronics shops here in my town don't seem to store them therefore i decided to use one of the junk analogue meter housing to serve the purpose.

Feed back: i would love to hear feedback from you fellow technician about your experience on this simple but very important workbench tool.

For those who like to use the 9 Volt battery for the power supply please use this adapter to get the 6 Volts for the circuits.
