Simple Inverter Updated:
A killer project if u ask me(literally)- Gave me quite a few 230v shocks while debugging but finally it works.
 
Hi, LMR

This is my first project working with ac mains.I tried the same project earlier with a hand wound transformer ,with magnet wire wound on a ferrite rod but it gave flickering results.Hence the toroidal transforrmer.The system produces a mild hum but a sturdy box enclosure might help nullify it.Cool project to have when the neighbourhood power station is down or just to install in your backyard.

Schematic Source :Electronics for You Magazine 

Technical Specifications:

CFL:               7W

Transformer:  Toroidal Type 5A, 12-0-12,230V

Battery :          7.5AH SLA maintanence free

Check out the pic for scematic, working and all info you need !

Here are MY TIPS  if u decide to build one yourself:

1.Don't keep the secoundary open while testing.It can go to a lethal 1000V.

2.Use high wattage resistors if u have them.

3.I melted my breadbord prototyping it.My suggestion is to build it dirctly on pcb- incase you wish to build it.I've already tested its validity:-)

4.I used a toroidal transformer.Use them to have better performance.

5.When testing the device try to use low wattage cfl first.Immediately switch off device if cfl flickers.It implies wrong connections in circuit.

In conclusuion, I would say it is a cool project to try if you want to learn about working with AC.

Cheers!

As soon as my end term exams finish...

That was pretty awesome.  I'm with lumi, any schematics and more information about your project would be much appreciated. Good show!

The video makes it a bit more clear .-) But please more infos, schematics and failures you had to face during the build. We are eager to know more about every project :)
