2x arduino = 2x flaming?

I wonder about the sound quality of that system, since zigbee, if I remember correctly, has a maximum speed of 250 kbps, which is about medium quality compressed mp3. Bluetooth can reach speeds of 24Mbps, which is enough to do extremely high quality audio, or even video. Then again, Wi-Fi 802.11n can reach a maximum theoretical bandwidth of 600Mbps. All of the numbers are the theoretical maximum (except maybe the zigbee), so you can probably expect half or less actual throughput.

So in summary, I love the idea (have been wanting to do this for a while), but for concert-quality sound, other wireless options would have to be explored.

On a more random guitar note, anybody think it would be possible/plausible to design a pickup system that would be able to analyze every string simultaneously and convert the note(s) being played to a MIDI output?

@Squirrel: MIDI pickups have been done. Just Google “MIDI pickups” and you’ll see quite a few. Or were you talking about a DIY setup?

I’ve used an older Roland system, and it tracks fairly well, albeit with a slight lag.

@Ryan Google Pete Townshend

@nate of course it’d be DIY. This is HackADay after all. Maybe using an xmega (not sure if you could get a fast enough sample rate on 6 inputs simultaneously with this) or an external adc with enough sample rate and enough resolution to successfully capture sound waves (so a refresh rate of ~22kHz, not sure on the resolution) then just measure wavelength and pass on the notes based on the wavelength.

Sound is nice, but the video sucks. Why did you make it blur in and out, really downgraded the vid. I wanted to watch your hand movement.

Looks like a clean job.

Here is a cheaper version :

The cameraman needs to be beat in the head with a tripod. Cool hack tho.

i came up with this idea a week ago!! way to beat me, good job

@ Squirrel,

Just designed and implemented a design for 6 monophic inputs to MIDI output. Very possible, not extremely hard.
