    First generation devices with rework and frequency adaptation

    I have bought a few of these after market devices that are very useful but have been discarded because they are reworks and some have quirks, jerks or shocks that they ended up with, in the reworking. Most failed because of bad or wrongful manufacture of a piece of the device that connects to...

    smart kegger is wired wrong! The skyblu wire and the w/blk wire are reversed... this is a refrigerator defrost sensor, and the CV freezer room switch that are reversed, (that CV room, thats my beer lagering room... very very important to maintain the proper temp!) can't have reversed leads here!!

    General Shortouts and Opens

    Expecting a great turnout for this thread!! I am at odds with this discussion already, so maybe we can lose the rhetorical whoo-haw and just think for a minute. When a short occurs, it usually dumps a bunch of power to ground causing some things the board runs, to just quit working...

    portable radio stations

    I have been using radios since high school, but it still bothers me alot that the industry made such a stomp over the use of SSB and linear amps. I have this marine band boat radio and some parts that should make it functional, but I don't want to look like a novice because I'm not. I would...

    off topic problem with fancy smart kegger and gas, fluid cooling system.

    I got the compressor and electronics working(a miracle in itelf)... The fridge compressor is empty... or at least ...it has no pressure in it. There are 2 ports. One on the "filter" and the other on a stub that enters the compressor. Which one do I put the refrigerant can on and which one do I...

    refraining from off topics in the lounge.... "What are the chances"...

    If a multi-layered device has a missing component,:confused: and you are capable of understanding the entire device and what it does, what are the chances of finding out what the device does, and bypassing or manufacturing something that will work? :oops: My smart kegger fridge of course is...

    holder glues on cheap boards

    I have seen a lot of pucky on boards, and I also have removed some things I thought were melted holders or clamps or supports that I thought got hot. I fixed my battery issue on my SD-1 Synth and put a battery holder on it so I don't have to do any soldering when I change the battery. The main...
