Pop goes the electrolytic and the tantulum.
After a couple of months the output fell to about 2.6V under load, 3.3V with the ucsimm module popped out of the slot. Be careful with the polarity of the wall wart plug. Looks like the regulator is dead, or you have a short in your board. You don't need to have the uCsimm on the gardener board to test the power regulator. You'll need to fix that or you'll damage the 3.3V parts.
