flowersrj said:  jimcking, A slight physical variation allows me to go under a bed looking for cats and also direct light at where the camera is looking.  I reversed both rear blue led lights (left to right and right to left) which opens an area that I could fish the wires inside so I did not need to drill any holes in Rovio.  I also have the blue led lights disconnected by unplugging the ribbon cable from the board.  Looks kind of froglike now.   I am hoping the brass piece is temporary until I find some kind of bucket sorta like what slippery has under Rovio to insert bulbs for more directional light.  I definitely can see well enough in total darkness to navigate--just haven't found those darn cats yet !!  -rich

professorpg said: opps I put it together with only one mag 3 watt 4 cell and it worked for about 40 seconds and burned the bulb out. Rovio is working fine otherwise, his old lite is still working. Did I have to put in 3 lights? Obviously I am new at this. Thank you for the anticipated help.

 When I tested my 2 Maglite LED setup, I noticed that they get H.O.T .  This was on the Rovio batteries.  So, I hooked them up to 4 Regular AA Duracells, and they still heated up.  Had them On for about 2 minutes, before I started to get nervious. So I found some Flashlights with Aluminium Housing, to mount the LEDs in.  Hopefully this will displace the heat.. Here are some pictures,  not finished yet.   Will post more l

Cool!  I like your set up.  The flashlight lens should also focus the light better.

I have run mine for a long time without any additional heat sink and they seem to run fine.  The modules appear to be thermally protected.  It will decrease the current if it gets too hot.  They do run pretty warm though.  I used epoxy to hold the modules in Rovio.  That helped to coduct the heat into the shell of Rovio.  It runs cool enough that I can still hold my finger on it after several minutes of operation.  As the spec states they will dissipate 3 Watts of energy.  It does not give any spec on how much light it will put out.  They seem to be pretty bright though.

So I Flipped the diode around connected to the leds and it comes on, but the Relay gets stuck on.  Is there anyway to do this without connecting the built in light?   I see the battery is a 6v and the realy is a 5v is that why it's getting stuck ?  Please Help!

You do not need to hook up the internal LED.  If you do not hook up the internal LED, you do not need the 150 ohm resistor or the diode connected to it.

The relay is running from the regulated 5 Volt supply inside of Rovio.  The 6 Volts is for the 6 Volt 3 Watt LED Module. The relay should not stick.

Mofetti said: Thnx for the quick reply i'll try it that way. It seems evrytime I start the lights the relay sticks hmm I bought 4 on the third one now. Can u think of why when I wire it up that way it only works with the diode in reverse of your diagram? I guess the main thing is why does it keep sticking hmmm.

It should not work at all if the diode across the relay is put in backwards.  In fact is should burn up and smoke the diode.  The other diode is for the internal LED and is not needed if you are not using the internal LED.  Are you shure you have the white wire cut and have the relay coil connected to the lead going to the Rovio computer board and not the lead going to front LED board? 

 All I can think of is check the wiring to make sure it is correct.  Several people have built it and it works fine.  The LED Modules get real warm after they have been on for awhile and some folks have added heat sinks to keep them cool.  No one else has reported the relay sticking.
