KiCAD Schematic Tutorial

Oh hey, remember me? Yeah, I’m the guy that’s supposed to be running this site. Sorry for the long absence. I’ve been consulting, recording my electronics radio show, managing a multi-blogger engineer site and even getting married! Jeez, it’s been a busy time. Anyway, things have cooled off a bit, so I’ve freed up some time (for now, never know what’ll happen).

I decided to dive into a new project after a long hiatus from hobby type activity. I plan to put an MP3 player and output stage board into an antique radio enclosure. I also decided to document the process, specifically using the open source board layout program, KiCAD. I’ve been talking about learning the software and doing the videos for a while now, so here it is! The first installment is the schematic capture. I’ll add more as the board gets more complex and I need to dive more into the process of actually getting a board fabbed. I’m excited! Hope you enjoy the video and the ones to come!


Featured on EE Web!

I was contacted a while ago and dragged my feet, like any good engineer. But today I was the “featured engineer” on EE Web! Exciting!

Aside from the fact that it was very nice of them to think of me, I’m just as excited to be featured on there along with friends from the electronics scene! My co-host of The Amp Hour (who probably won’t let me forget who was interviewed first), Dave Jones has been featured in the past. My co-conspirator for the recently completed 555 contest, hackmaster elite Jeri Ellsworth has been featured. And someone else I really respect from the hobbyist scene, Limor Fried of adafruit.

If you haven’t checked out EE Web, I suggest it. They have a really clean interface which I like for browsing their articles. The forums are still a bit light on participation but hopefully will fill up with knowledgeable people soon. Thanks again to EE Web for featuring me!

My Electronics Workbench

Aside from the 555 contest I mentioned in my last post, my February was spent building the workbench I drew in Google Sketchup. It was built partially for The Amp Hour, partially for circuits I plan on building and showing off on here and partially for my new business, Analog Life, LLC.

So for today’s show and tell, I’ll premier the first video ever with me in it on YouTube:

I also had a couple snapshots of the bench in progress:

So my bench is done now and I’m off to put it to good use!
