International Karate (C64 music remake)

A Commodore 64 game music remake

I decided to do a quick remake of a C64 game song, just for fun.
Though I own plenty of VST synthesizers, the goal was to only use analog synthesizers and no overdub, i.e. only one instrument per sound. So you only hear the Juno-60 playing a single sound for instance.
I didn't know which song to pick, but after a short while chose the main song for the game International Karate, composed by Rob Hubbard.

Actually, I'm not too pleased with the result.
Some sounds (like the first one, heh) have an annoying ringing that I didn't bother removing. I guess I'm using too much resonance...
This was just a quick experiment so I don't care if it doesn't sound all that good.

Anyway, I thought I'd share it, so here it is:
(Update: I replaced that first sound with something better, so it's not piercing your eardrums any longer :) )

Repairing an EHX Super Space Drum

Electro Harmonix SSD repair

Somebody had noticed I had done some repairs on my own gear and asked me if I could take a look at an EHX Super Space Drum that wasn't working.
Symptoms were that it started to not trigger well until it finally gave up and refused to trigger at all. I had absolutely no idea what could have caused it and my initial thought was some sort of bad connection or other mechanical problem.
I had never repaired anything for someone else and I didn't have any pressure on me really. It was more of a "just see if you can do something about it" request, so I thought it'd be fun to give it a shot!

Unfortunately I forgot to take a picture of it so I'm using a frame of a video clip I made with it :)
The picture is from AFTER I had serviced it. Read on if you're curious about the alligator clips to the left.

Lab power supply blew up


So, I was sitting trying to figure out why an EHX Super Space Drum (which I was repairing for someone else) wasn't working.
All of a sudden, I heard a loud pop, like somebody claps their hands once, right next to your ear.
It was really loud and felt like it almost started ringing in my ear.
Of course I had no idea what it was and got really scared I had blown something up in the EHX thing I was repairing, because it wasn't mine...
Though, I suspected it was the power supply, because .. what else could it be? It sounded like a capacitor blowing up. So, I switched it off and continued my repair using my other power supply...

When the EHX thing was done I opened the suspected power supply and looked inside.
This is what I found just laying on the bottom...
Yes, it's empty.
