The dimmer for my room
« on: June 05, 2009, 20:57:29 PM »
Hello frends!

I want to make a project for my room. The project is a 4 light dimmer. I am not very good with electrnics and i want not mikrocontrolers or other very hard things. Easy circuit.

I want to make it with 4 state. First off. Then i click one and turn on soft. Then i click again and light more. Then i click again and light 100%

I must make it with PWM? And how many lamps can i dimmer? Can i dimmer economy lamps?

Finally, it is better the switch to be a touch switch  :D but not very important.

Can you please drive me for first start? For example what kind of circuit i use?

Thank you!

And next click off, i guess  ::)

No. You make a dimmer... Check out this dimmer theory.

Indeed, it is not important, but it is fancy, isn't it? Check out the QT110 or QT116 touch sensor. This would do the job.

Well, you need a dimmer circuit for sure. Then, you need 2 preset values (30% and 70% for example) to do the dimming. A switch (or the QT touch sensor). And a decade counter. The switch (.....) will clock the decade counter. When in 0, light are off. One click and goes to 1, that would set the first scale. You got the point. At count 4, the decade counter will do a reset and go back to 0. You can use a decade counter CD4017 for example.
The 'Hard' part is to change the dimming with the 2 outputs of the decade counter (output 1 and 2, as 0 will be off, 3 will be full and 4 will be reset). For this, you could use a comparator. Each output would drive different voltage to the input 1 of the comparator. The other input should be connected to a transformer and a full cycle rectifier.... Just an idea.

But, the simplest would be to use a dimming chip with touch plate...easy and small. TT8486A/TT6061A is the answer to your problem...



Thank you!
You are welcome

Nice chip but i think it's fancier full fade in -out dimmer. :)

i have told you 1000 times, it's not the destination that counts, it's the travel... :P

Thank you for your support!

Kam: With the TT8486A/TT6061A can i dimmer economy lamps?

Can you show me a dimmer with the TT8486A/TT6061A?

Economy lamps cannot be dimmed with a normal dimmer. I tried it and failed. I think you need dimmable balasts but i am not very sure.

As for the dimmer circuits, if you google for it you will find thousands.

Here is one for you http://electroschematics.com/2353/touch-dimmer-switch-circuit/
