PF Light: How to invert one of the LED's?

[marook]

Hi All,

I'm doing a project, and would like to inverse one of the LED's in the 8870 PF lights.

Seem to remember I saw something about this on the net long ago, but can't find it anymore - best I can find, is schematics over here.

So, the big question is: Is there any MOD so the one LED lights up at +1 and the other at -1 on the output?

 

Any inout is welcome.

Are you familiar with a soldering iron?

If you bypass the diode bridge and revert one of the LEDs, one of the LEDs will light up with positive/direct voltage and the other with negative/reverse voltage.

To bypass the bridge you may solder one of the ~ to the + and the other ~ to the -

Hi Alvega,

Yeah, I'm familiar with a soldering iron, just need to find one ;-)

Thanks for the hints - will see if I can figure that out. It's been a long time since I did diagram readings.. ;-)

OK.

Be carefull not to short the + to the -

The LEGO battery has an internal protection to prevent overcurrent but just in case test it with used alcaline batteries.
