Editor in chief

Michael Dunn is editor-in-chief of EDN, and has been messing with electronics almost as long as he's been walking. He got his first scope around age 15, and things have been going downhill ever since. Scopes now vie with wine racks, harpsichords, calculators, and 19th century pianos for space. Over the years, he's designed for the automotive, medical, industrial, communications, and consumer industries, as both freelancer and employee, working with analog, digital, micros, and software. Since 2000, he's run the TekScopes Yahoogroup, now with over 5,000 members. He was previously editor-in-chief of Scope Junction: http://edn.com/collections/4422580/Scope-Junction-blogs

  • Whipping a cheap LED PSU into usable shape
  • I also noticed slightly improved performance on the new PSUs with the replacement cap: Better regulation going from no-load to 1.2A, and 9V @ 1.5A instead of 8V. Woo.

  • I Sing the Capacitor Electric
  • I tested "power consumption" of one cap across the line. Fortunately, the electric meter registered zero. Now, to try six in the cooktop junction box and gauge the noise-reduction effect. If it's significant, I'll install a new box in the basement just for the caps.

  • Simple trick lets you see your parts
  • Here's an ancient EDN article with general information on inspection lighting: http://www.edn.com/electronics-news/4382211/Choose-the-Right-Lighting-for-Inspection

  • Pedal effect circuit design: getting started
  • Any converters in a real circuit will be ∆∑ and will not have aliasing problems. I'm not familiar enough with simulation to suggest the best solution in THAT context.

  • Pedal effect circuit design: getting started
  • "Subtle harmonics"? Which ones are those? Seriously...you're discussing guitar grunge pedals, yet saying 16/44.1k isn't good enough? O...K... "Digital emulation of audio signals may lose subtle harmonics."
