bobc - there is nothing wrong with having OCD when playing with this stuff. :D Put me down for a v2 board when you get this one made. I haven't had the time to solder up the first board - too busy...

When someone got the same problem with the RAMPS-FD board (meaning, the Due which has the ground reference has the issue), they suggested 1kohm. I think you don't need to go that high. Even as low as...

I'll be getting some boards fabbed as well (well, 10 boards), which will be delivered to me in Aus. If anyone in Aus wants one, I'll probably have ~7 I can pass on (1 is already taken, 2 are for me).

Hi all! Today I bought a GLCD and I'm trying to connect it on my Megatronics V2, the problem is that I can't get any schematics to do it. Is it possible to do it? Maybe using the I2C is better. Thanks...

Those are a sort of smps idd, but are not voltage mode. They are working in sort of current mode, because thats whats relevant for leds. Usually there is a "led driver ic" that does this current mode...

I guess I should have been more specific (many LED stripes do include groups of serial leds plus resistors designed to be powered at 12V or 24V). This type of supplies [www.ebay.com] is what I am...

Oh ok, now i am getting it finally. You do have a smps that is meant to output 12v, and can be used for anything, incl leds that have resistors in series with a value suitable for 12 supply. Sry i...

I would try to scope out the signals on good vs bad power supplies to see if you can narrow down where the problem is. The symptoms you give are similar to the smps reacting to an over-current...
