I whipped up a layout yesterday...it comes in around 3.75" square, which isn't too shabby. I need to tidy things up a bit, but I thought I'd post it to get some feedback. Thanks in advance...

ble0t, I like your project a lot! It's much more compact than the board I purchased.
Can you please let us have the components' values and some specs?
Thanks!

Here's the .brd file for it...I cleaned up the silk layer and a couple little things.

As for the values / specs, they are identical to those in the schematic in post #7 of this thread and to ESP Project #39. The one difference is that I only had room to use two limiting resistors in the soft start circuit, so you would probably want to increase the size/wattage of these two as compared to the project.

HI,
how about radial power resistors to save space?
240v mains require about twice the resistance. Does that means twice the power dissipation?

That sounds like a good suggestion...I could definitely give that a shot. Thanks!

As for 240V mains...currently, the primary side of the transformer is wired for 120V operation, although I could add some jumpers to make it switchable between the two.

I'll work on it a bit over lunch and hopefully have an updated version later today

And the .brd file for anyone interested...
