I have gone through 1000 comments and I will answer some of the ones that is recurring a ton.

Q: Why did you not make the guitar be able to switch between guitar, bass and fretless with the motor?
A: That was the original intend of the motor, we had encoder and code all set up. However, I had to get this video out this year because I had already delayed it several months for the sponsor. I also spent 1 week burning up motor drivers and potentiometers because the first stepper I got was overpowered for the drivers. I’m also bd at electronics.
But one truly cool thing with positioning and stuff Is that you could have presets of neck movements. Like rhythmic spinning back and forth in patterns that fits the song?

Q: You should have used a slip ring for the pickups, it allows cables to spin.
A: This was the first thing that was tried, but I cut it from the vid. A slipring would work fine, it would just be slightly more complicated to integrate into the design VS bluetooth. However a slipring also introduces noise when spinning. I couldn’t hear any real life improvement vs the wireless system so I just went with the easiest for now.

Q: The guitar pickup should be mounted on the guitar in a curvature so only the front facing strings makes sound.
A: This was the first approach but some downsides didn’t make this solution good when going into the details.
curved pickups to this degree does not exist currently so you would have to invent a new method of making pickups. This would add 3-4 weeks to project minimum.
The height of the pickups is extremely important. If you look at your electric guitar you can see that each pickup is adjusted to the 1/10 of a millimeter for that particular string. If the pickups doesn’t move with the string. The loudness would be impossible to balance.
Using single pickups, the string could land inbetween the pickups. Even if ratcheting design was used. The string spacing is not the same on bass section as guitar section.
I personally was more into the idea of spin chords and stuff and it wouldn’t work with this idea.

Q: You should have done xxx it would be way more practical.
A: This guitar is not made to be sold or practical. It’s entertainment engineering and I do it just because ‘it would be cool if’.

Q: I want to buy it, how much?
A: The cost would be ridiculous to buy this particular one. I think in total we put in 800 hours into this? But if you are simply interested in how much it would cost to build another version. I can try to break it down.
Headless tuners/bridges = 700-1200 USD in total depending on brand.
Custom made pickups = 450USD
Strings: 150 USD for a set ( high price for the giga thick strings)
Wireless system = 150 USD or something
Besides this, we mostly used PLA and wood. You could of course find workarounds to keep prices lower. But if you count labour cost of workarounds it would end up even more expensive likely.
