Robert Moog, may he rest in peace, invented a legendary voltage-controlled filter (VCF). It’s the low-pass filter that gives the MiniMoog its characteristic sound. YUSynth has published the schematics, parts list and PCB layout for the MiniMoog VCF.

Remember the 80s when your coolness factor was determined by the size of your boom box and the number of times you could spin on your back while listening to to Kraftwerk? Well, OK, maybe not, but this project is certainly a nice addition to any iPod and is great for picnics, outdoor parties and BBQs.

Let this your source of outdoor loud music: a really nice (industrial) looking homemade boom box. Just plug in your iPod or laptop, and you’ve got a party!

I’m guessing that there are thousands of tons of perfectly good earphones in landfills today, all because their owners threw them away when the mini jack connector came loose, broke off, or got all “squelchy”. This instructable should be printed on the packaging of the earphones when you buy them. It teaches you how to fix the connector when (intentionally not if) it gets damaged.

There’s one thing that bothers me about it though, it’s the look of the finished repair. Very sketchy. I would have used heat-shrink tubing instead, which would look much nicer and be super durable. This set aside, it’s still a nice and useful instructable.
