c programmer, embedded dabbler, power supply tinkerer. (also loser of three consecutive moderator elections on EE.SE.)

[formerly known as 'madmanguruman' but shed that identity after a nice conversation with Olin Lathrop at Microchip MASTERS 2014.]

almost 15 years experience with switching power supplies at two different companies in the greater toronto area. worked my way from production technician to sustaining engineering, then product development (electrical and embedded). also fluent in vba and labview. currently studying project management theory while working as a power supply designer.

comment What is the best and simple circuit diagram for a radio receiver to receive radio waves in Citizen's Band
Too broad - you haven't indicated (1) if you have any electronics knowledge and (2) what you have tried so far, if anything. "Design it for me" questions aren't really the focus of this site.

comment Most stable internal microcontroller clock
+1 @gbulmer. Which micros were considered and under what conditions, or was this a pure datasheet exercise? Under what conditions are you concerned about stability? The question seems overly broad to me as 'most stable' without any constraints or conditions lends itself to multiple, possibly conflicting answers.

comment How to improve current control loop in power supply?
Did you look at the output current with a current probe when regulating in CC mode? Looking at the voltage isn't entirely fair since the voltage loop is doing nothing at that point. What are you using as a load? (An active load has its own loop and can end up fighting with the PS loop, making a steady load look dynamic. Use resistors if possible)

comment Very intermittent power MOSFET failure
Further to the question - if I'm looking for a fault which I cannot replicate, and I find some 'badness' in there that makes me scratch my head, I would do what I could to fix that badness even if the root cause remains elusive. It sucks, but sometimes a rare, corner-case issue has to be fixed empirically, by making improvements and seeing if the failure rate over time and quantity improves.

Welcome to EE.SE. All in all, this is a pretty good first question. +1 from me.
