Sunshine on his shoulder makes him jumpy...

No sound designer can resist sound-making objects, so I did some recent damage at ThinkGeek for some small, inexpensive musical items…but then I noticed the robots.

Sadly,  buying a spendy mechanical robot arm just to record servo sounds seemed like a horrible investment. I learned this lesson last year. ;-)

However, I did get a tiny solar-powered grasshopper kit. An offset actuator in its abdomen makes the whole thing vibrate on tiny wire legs when it’s solar-cell carapace is hit with sunlight or a strong halogen source.

Of course, that would sound tiny and delicate. Which is OK. But how to make that sound bigger? Well, you put it on something that will resonate: Something with air around it that will conduct vibrations easily. (I’ve had loud, racous luck with this before.)

Being a hot, sunny Sunday, I chose the top of my closed Weber grill. I tested the sound with contact mics, but the steel was too thick. Truly, and unusually, where my ears were – close to the top of the grill – was where the best sound was. I switched to a hypercardioid mic in a windscreen, and captured today’s sound.

To accentuate the lovely low-mid resonant tones, I applied a huge -24dB cut at 5.5kHz , where the metallic feet where vibrating against the grill (I still wanted a tiny hint of chatter  in there), tand a +9dB boost at 180Hz. Could make for a nice layer with some other design elements.

    Wow, sounds like a drum roll in my head. The resonance is HUGE. Love it.

    Great Sound, Nathan! That’s a very cool “natural” resonance. Nice toy :-D
