Hi, I just found this forum...
There's not a lot to say about me, besides that I know the basics in electronics, and I love it! I always have enjoyed to repair (or at least try to!) everything I can.
Well, I'll do my best to lend a hand in every way I'll be able to!
See you around!Comment

Good to be here. Had no idea about any of this stuff until it was needed. 😖
Hopefully I don't brick this device beyond what it is, and I hope to learn something I can use to help someone else in the future!​Comment

Hello everyone! My name is Joe and I am living in East Berlin, Pennsylvania. I've been in the IT field for almost twenty years but I just decided to dive in a bit deeper and start to get into the nitty gritty of electronics board repair. I'm in the process of setting up an electronics lab in my basement, so far I have a Yihua 992D-II, a Yihua 948 D-III, a Riden RD6012P-MAX, and an OWON XDM2041. Still looking for a good microscope and a thermal camera.
I heard about this forum from watching videos from Graham Lord (a.k.a. 'Adamant IT' on YT).
Looking forward to being a part of this community.Comment
