Thanks, the next time I take it apart I will switch out transistor types.

Maybe the schematic should be updated on the wiki?

Not a bad idea

Or is the transistor issue the fact that maybe we are using different LCD displays?

I just had one laying around so I used it.

That's because PNP transistor requires different signal than NPN - NPN with zero signal on the base will cut the current and PNP will cut the current with the high setting. That's why LCD was not dimmed but was brightened to the max. To make it work with a PNP transistor you would need to change the code to dimm LCD with the "high" voltage.

Thanks for the input. I will try modifying the code before modifying the hardware.

AndrezejM, thanks! I was able to edit 2 lines in the code.

My brightness now works as it should instead of backwards.

I will report back if the light now turns off after a timeout period.

Which version of the code have you modified? There's at least 4 versions of that...

I am not entirely sure.

I will attach it here if you feel so inclined to look at it and fix my dumb dumb editing!

That's a very old version of the code. I'd recommend using code described here: http://ecomodder.com/forum/showthrea...tml#post381830

Thanks for the information. I will check that out!

On a side note, the pre-assembled mpguino I purchased on 3/4/15 is FINALLY scheduled for delivery today. That's the one I will be running.

The one I assembled was mainly to play with it and get some experience dialing it in.

Hopefully the vss fine tuning I have done will apply to the pre-assembled unit!
