Build this 20 watt Fluoro Inverter, it drives two 20-watt tubes or a 40-watt tube! It’s a circuit you can put together from junk box components or build from a kit. It’s very simple to build and requires no printed circuit board. The transformer is hand-wound on a ferrite rod (from an old transistor radio) and the winding wire can be salvaged from an old transformer.

The meaning from this design is to build it in -i.e. a shaded lamp- and to switch this lamp on and off the normal way, just like it was switched before the dimmer was build in, then you could by exception dimming the lamp more or less with your TV remote control.
When you switch the power on there will follow a soft-start till the lamp burns at the previously adjusted dim level.
With the ’0′ button in TV mode you can dim the lamp, turn more and less bright.
The remote control should send more then one RC5-signal per button-press seeing that the first one is ignored, this does imply that when the remote button is pressed a short time, there nothing happens.
With the P+ and P- button from a system at choice you can adjust the maximum and minimum dim-levels and with the ’1′ button the start-up brightness.
The next time when the 230V power is switched on the lamp starts up at the adjusted dim-level.

This is a device for adjusting lights in your home with any type of remote controller (tv, dvd, video,..). Today we are using many devices in our homes to improve quality of our life and this is another example on how you can enhance a simple procedure like switching the lights ON/OFF. It may be difficult to many of us to stand up from our chair only to switch lights, so try imagining yourself doing this with your remote controller.
