Weekly DIY Music Thing

Weekly Music Thing No. 2 : Inductive Pickup

This week I’ll show you how to make a pick up that will let you eavesdrop on the internal sound-world of electronic devices.

The inductive pickup is simply a coil of wire, really that’s all there is to it. Connect that to an amplifier and begin probing your: Laptop, mobile phone, local transport network (London underground tube trains sound amazing!)

As last week, a video follows….

 

NEXT WEEK: either ‘How to make really good contact mics’ or ‘Messing about with CMOS chips to make a horrid noise” or something altogether different, you decide!

Weekly Music Thing No. 1 : Laser Microphone

Here is the first ‘Weekly Music Thing’! In the video I take a look at how a cheap laser pointer and a solar cell can be turned into a remarkable optical microphone. I say microphone, but I think that might not actually be the correct description as a microphone converts sound into electricity where asĀ  the laser mic turns light into electricity via the solar cell. It’s more of a Phosophone! Watch the following video for what you’ll need to build it, and I show a few ways it can be used too. I particularly like the fact that you can create sound bouncing the laser off a vibrating or moving surface. Used like this patterns of light and dark create audible tones. It’s supremely simple, fun and cheap which makes it a winner in my book. Have fun and don’t point the laser in your (or anybody’s) eye holes!

Let me know if you find this at all interesting and I’ll do some more….

Announcing my intention to do a Weekly DIY Music Thing…

Err yep, I’m going to post a new project that you can make at home, every week starting now. My last post about making Piezoelectric crystals at home seemed to be something of a hit getting featured both on hackaday.com and CreateDigitalMusic.com so I thought I’d give you more of what you like while building a sample library for my own compositions.

I thought of covering:

  • Contact microphones – construction and creative usage
  • Simple electronic music circuits – warm up your cmos chips
  • Prepared instruments
  • Max/MSP usage – Maybe some generative stuff?
  • Arduino
  • DIY music controllers
  • Studio techniques

If you have any ideas please comment here and I’ll try and cover them. Keep your ideas simple and doable in a 5 min video!

Next time you see the soldering iron logo there will be a tutorial under it.

Take care,

John.
