DSO SHELL 150 K, busted rotary encoder + fix
Update : There is simpler way to fix it. I had a DSO138 which is a very fun and cheap to do low end oscilloscope job For basic hobbyist like me, it's perfect I saw the new generation (DSO150K) with improved user interface, so i bought one All went well, until i realized i managed to do *2* mistakes : * Solder the power switch the wrong side, not a big deal * Solder the rotary encoder the wrong side => That one is a common mistake it seems After trying to unsolder it, realising there was a shortcircuit, fixing it again and breaking the small PCB holding it, more and more, i completely ruined the whole thing. I had to dremel the original encoder out and cut the tracks to stop the shorts. Ultimately, I managed to make it work, it's not that complicated. First, I bought a new rotary encoder. The original 4 pins header is connected to r5/r6/r7/gnd If, like me you ruined it completely, you can solder small wires to r5/r6/r7, a...
