Circuit Skills: Function Generator Video

Build a Waveform Generator and Enclosure

By Collin Cunningham

You may be good with chips, solder and a breadboard, but a professional creation requires a proper enclosure. Make Magazine's Collin Cunningham takes you step-by-step through the process as he creates a waveform generator.

Every Useful Circuit Board Deserves a Good Enclosure

Providing a proper case for your circuit can protect it from accidental spills and falls – plus give it a cool look you can proudly show off even to those unfamiliar with soldering and such.

Personally, I'm a big fan of designing and casing up my electronics projects. The sturdy and functional results always leave me feeling a little impressed with myself, and I'm often surprised at how useful the completed device can be. In the above video, I set out to build a basic waveform generator for testing and experimenting, but I ended up with something I'm more likely to use for noise-jamming, synthing and well... just plain fun.

If you'd like to build your own waveform generator, check out the Function Generator Bundle. It includes all the pots, switches, enclosure, kit, etc – just add wire and a 1k resistor (for the LED). If you decide to build your own enclosure kit, we'd love to hear about it. Send your feedback to [email protected].

Oh – and in case it helps anyone, below is the wiring diagram I followed in the video.
