 Bigger Bigger  Smaller Smaller  Reset Reset

I've finally managed to complete my first installed project in our house.  Installing 32 white LEDs on our bedroom ceiling to imitate a star field.  Each LED is individually controlled from a Seeeduino, using two TLC5940 chips for fading them on and off.



There's a video of them in action, along with a more detailed description of the project along with code on my website.

Anyone else in your house? I don't think the other people in my house would let me do anything like that!

Looks interesting  smiley-wink

I've considered doing this, but live in a unit, so not sure if the property owners would appreciate the holes smiley-grin

Nice work!

Well I don't think there are any holes, just white tape, wires and LEDs.

I don't think they would appreciate walking in and wondering why you have a bomb connected to your ceiling!  ;D

Thats why you attach an LCD with a countdown and a message saying "Leave a good house inspection notice, or don't trip on the pressure pad under the front door"  smiley-razz

Sounds like a plan!

Fortunately my wife is pretty understanding of these things.  smiley-grin  The only holes are where I had to mount the control unit, as you said, everything else is held up by tape.  Its definitely a plus to live in a house you own, where you can pretty much do what you want, and don't have to worry about leases or inspections.

Nice project.  

I want to try and put this together and found these:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220544554229

Not sure if it's a good deal or not.  There were others but I noticed
they were tlc5941s and only 80ma.
