Welcome back everyone… or at least, welcome back to myself.
I took the week between Xmas and Newyear off, and caught up on some non-electronics.
I have a few things in the skunk works, not that they’re really secret or anything, but I’m reserving a lot of details until the projects are farther along – hoping to write up some articles rather than just short posts in the blog.
For now, here’s a few pictures:
switch mode power supply … this circuit is a buck converter or step-down regulator … it’s programmed to supply 500mA into a load (constant current regulation). With my load (seen below), I measured about 90% effiency.
four warm-white Luxdrive IO Moon leds, two watts each, using Nichia Jupiter leds (click for larger picture)
