Open hardware pbxes explode

David Rowe keeps plugging away at developing the second generation of his entirely open hardware/open source pbx system. He keeps publishing great in-depth technical articles on his progress on developing the hardware and software. To catch up, read Part 1 and Part 2.

(His work has also been featured in Linux Journal)

David mixes in the human realities of engineering in with the actual engineering, too. Engineering isn't all dry logic and mystical symbols. Sometimes you get to blow things up!

In today's installment (part 3) David fries a capacitor:

BANG! A small mushroom cloud rises a few inches off the board and gently drifts across the bench. A nasty smell fills the air, as does my equally nasty string of expletives. My 8 year old son runs in and surveys the damage...

“Dad, can you do it again?”, he asks, excitedly.

I summarily eject him from my office, expel a few more choice words for Murphy and bend my nose over the board to sniff for the error.
