Hi all. Just joined after lurking for a bit. I'm a computer guy by trade, but have been dabbling in electronics since the mid 70's
I do mostly repairs, though occasionally I'll build something. Even though I've been doing this a while, my electronics theory and circuit analysis skills are pretty lacking, but I can solder really well, and only rarely blow something up by slipping with a scope probe or meter lead
I enjoy the challenge of repairing stuff that would otherwise get junked, LCD Monitors TVs etc. At work I repaired a $700.00 conference phone for the cost of a $0.33 capacitor. Just finished repairing a Bose Lifestyle 5 stereo unit for a friend and total parts cost as about $12.00 (with shipping)
One of the projects on my to-do pile is a Cisco (Linksys really) POE Gigabit switch. I have no clue how the internal power supply is supposed to work (it runs on an external 48VDC supply and there are no lover voltages present inside, so something dead in the internal regulation circuitry. I will probably grab some datasheets on the parts in that general area and start hacking away. May start a thread on that soon.
Anyhoo, that's me.
