Doug_S - It's incredibly easy to find schematics or other documentation for just about anything online. There are also tutorials for quite a few broken things. And, more parts seem to be available.

Why do you say it is becoming viable again?  What is it about the failures of these recent devices that left you able to diagnose/repair them, versus the failures of devices a decade ago that you couldn't/didn't?

part of why some of them are repairable for me is that there are great tutorials out there. I've replaced capacitors on a couple TVs that I never would have found on my own, but they were documented issues.

Caleb - looking at engineers like Jason Kridner (Ti Beaglebone camer and other projects) and Jeff Keyzer (Geiger counter, GHz Amps & such), I'd have to agree with you that there are engineers who still enjoy creating when outside of the corporate walls.

Many years ago, in a galaxy, pretty much right here, I'd expect to fix just about any electronic device of mine that failed. Somewhere along the years, component level repair became too expensive, too complex and in general, impractical.

However, along with the recent hobby re-revolution, that's been changing. In the last year, I've successfully performed component level repair on an LCD monitor, a gaming mouse, a digital camera and a few other similarly complex items. A decade ago, that would have been unthinkable.

Has anyone else found home electronics repair viable again?

I think there are electronics hobbyists from all walks of life, especially now that we have fairly easy-entry things like arduino. I've known several engineers who have enjoyed the hobby as well.

I'm curious. Hobby electronics has exploded over the last few years. Has any of that been connected up with professional engineering? Like, do engineers-by-day become hobbyists after hours? If so, has that necessitated an increase in soldering skills?

I don't know that they NEED to. I think everyone could benefit from being able to solder though, even people who aren't in the engineering world. Well, except for wizards they can just do whatever they want.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
