Introduction: Fun With IKEA Lamp

Nothing special.
Nothing new.
It's just my own version of mood light with famous IKEA Mylonit lamp.

Step 1: Take It Apart.

Leave bottle alone.
We are going to play with bulb socket.

Step 2: That Was Easy.

Let's bring some parts back into the business

Step 3: Where's My Junk Box?

Small piece of plastic will serve as a base.

Step 4: Screwdriver Is Required.

Attach spring loaded bracket to the base.

Step 5: User Serviceable Parts Are Inside.

Now it will be easy to remove electronic guts if you have to change broken glass .
I've already had bad experience. ;-(

Step 6: Engine.

My little boy PIC12F683 does all job.

Basically this device is programmed as three channel PWM oscillator.
Output of each channel can be connected directly to LED or to power transistor which drives chain of LEDs.
Channels corresponds to Red, Green and Blue colors.
PWM duty determines brightness of LED.
Duty value is randomly calculated and current data is stored in internal EEPROM

There are four different working modes
- slow fading;
- slow switching;
- fast fading;
- fast switching.

Device continuously cycling through modes.
Upon powering up last stored data is used to calculate new duty values so color sequence is always new.

...
Preprogrammed chip available upon request.
...

Step 7: Last Step.

Fasten board to the base, glue power jack on its place and solder it to the board.

Step 8: All Done.

Finally!!!

Step 9: Power It Up!

Get some beer from the fridge, grab a chair and just relax and watch :-)

I made one of these years ago, sadly last month I smashed the lamp :(

So off to Ikea I go...The don't sell them any more :((

Hi! thanks for this project... I found the music that you used for the video, great... wold you say who is the composser? the name of the song?... Thanks!

It's "Merry-go-round of life" theme by Joe Hisaishi from anime "Howl's Moving Castle".

Hi... You made your 12F683 work as a 3 channel PWM.... I know the 683 has a CCP module with one PWM output. Did you create three PWM's in software ? because i don't get it. PIC12F683's CCP's PWM output is on pin 5 and you use pins 5-6-7 !

Yes, PWM is implemented in software so I can easy add channels and any pin can be used as output.

Hi, Can you upload some video how its work? Tomy

Wonderful Work! Congratulations!

Any chance you could update this? I've built it and it works really well, but the diagrams in the zip file and the ones in the instructable are different so I've no idea which way is 'right' for the hex you've supplied. Also, I'm assuming you used CCS C to write the program. Is that correct?

I've build few projects with different types and quantity of LED but chip and firmware (HEX code) are the same for all configurations. Only difference is way to connect load to chip. Regular LED with working current up to 20 mA can be directly connected to output of microcontroller. High power LED or light strip should be driven by power transistor. ... Yes, I use CCS C in my projects.
