Dear #synthdiy Mastodon: I have an NLC Squid Axon with a burnt component (I’m guessing a capacitor from the shape). I really want to get this fixed, but have never picked up a soldering iron.
Is it doable for me to fix this myself given my lack of electronics experience? What’s the minimum I would need to know?
I’d like to be able to attain a sufficient skill set to repair my modules, but not sure what the most efficient way to go about that.
Any suggestions are welcome. I’m missing my 🦑.

This is a 10R resistor which gave up its life to save the rest of the module. It was there exactly for when someone got their stripe the wrong way round.
How do I know? I looked at the NLC build guide for the squid axon.
Normally this task is undertaken by a diode, btw.
Should be straightforward to repair.
The difficult bit is desoldering it without ending up with a blocked hole. (Lol).

@Number1SummerJam And here I'm tilting the module to give a better view of the fried component in question.

Here's the rear face. The burnt part is in the upper left quadrant, unsurprisingly near the 10-pin cable connector. Although I'm usually assiduous about aligning the red stripe on the cable properly, it looks like that time I got it wrong, hence the damage.
Unlike some of my other modules, prying this one apart appears to be non-trivial, so I don't have a pic of the back of this PCB

@flockofnazguls Got any pictures of the damaged component? Both sides of the circuit board

Fwiw I taught myself to solder this year, and if a shaky handed old git like me can do it, anyone can.
I use a miniware ts101 iron. Make sure you've got good light and a magnifier. Practice first. (you can buy practice kits on eBay).
Buy yourself a basic set of decent tools too.
The ai synthesis guy has a nice page on DIY, with suggestions for a base toolset

He's talking about building modules of course but it's all applicable to repair too.
He also links a lot to Amazon but Amazon are arseholes.
Lots of modern modules are smd & that's a bit of a different skillset, but again, I learned it so anyone should be able to

It's a 10R

@flockofnazguls It definitely looks like a blown electrolytic capacitor- you can see the oily substance leaking around it. Since it’s a thru-hole component, it would be easy to solder and replace. Make sure to find the exact component, replace with the exact polarity and find a data sheet with the maximum temperature rating. You can use a soldering iron (a cheap Chinese one with temperature control will do) and make sure to apply flux paste before soldering 1/2
