ince everyone is being so social, I guess I can adapt...
Started in electronics doing ATC maintenance in the USMC for 10 years. Did four and half years with a company out in Oregon. Did a bit of traveling there.
I like tinkering with anything electronic. Mostly the hardware side. Jack of all trades, master of none.​Comment

Hi all Bingers here. I'm currently an electrician primarily working on energy storage systems but my first career path was as a field service engineer. Mostly worked on high power laser systems and the associated electronics and computers. Built a handful of desktops for myself, friends, and family. Always love learning about the inner workings of various tech.
Well anyway I'm typically a lurker and only prefer to comment on something that I am very experienced in. Be well everyone.Comment

Hi! I left Russia 1.5 years ago to raise my son among normal people. We live in France without documents, the income is small. I have to come up with something. So I got the idea to get involved with computers. I don't have much experience yet, so I buy old ones, upgrade them, and sell them. Little by little, people ask for help. There is not enough equipment, as well as experience, and I am constantly looking for solutions to various problems. I hope that one day I will be able to share my experience. Good luck to everyone)Comment

Greetings all! Thank you for allowing me the opportunity to introduce myself. I'm an amateur repairer, and mainly do it as a hobby.
Most of it is junk I pick up from time to time like CRT TVs/monitors, game consoles and controllers, and I'm just starting to mess with laptops. It's mostly board level, and my success rate so far isn't terrible but hopefully the good people here and their wealth of knowledge a can help better those stats haha
Thank you again for having me, and I hope I can be of as much help to you all as you will be to me, I'm sure.Comment
