Wow. Life can sure get busy in a hurry. I have been working on several projects in my extremely limited spare time and I will try to post something about them soon. Honest.

In the meantime, have you ever designed your own DC power supply? I have designed and built a couple of switchers, mainly to take 12V DC and push it up to 170V DC for Nixie tubes. These are low-current designs. I'm currently contemplating constructing a junkbox power supply that will supply 20V DC @ 5A. This is a little different beast and will be implemented using a transformer, bridge rectifier and a bunch of smoothing capacitance. I haven't decided yet whether I want to add any regulation to it or not.

Feel free to chime in with your thoughts.
