tl;dr don't bother. This is too abstracted and nuanced. That is okay to skip.
I like to understand the abstract scope of engineering. This is way beyond the simple surface level, with pics below to illustrate my point.
With electric guitar pickups, the complexity of field shaping and design control over the sensor seems like a place where optimising the profitable manufacturability of the final product remains the primary constraint with little deviation.
I struggle to qualify and quantify my intuitive hunch that there is a whole lot more potential to engineer something new and better within the realm of modern manufacturing. I don't know the principal questions I should ask or what might disprove my ideas from the get go.
- Most transformers shape the magnetic field far more than guitar pickups.
- a guitar pickup appears to be more of a two dimensional sensor that picks up the motion of a ferromagnetic string in the two primary directions of motion
- there are more complex harmonic motions present than a pickup can register in two dimensions
- the coil and slugs of a pickup are surrounded by a single large winding, yet the strings each have very different frequencies
- it is now possible to make a powdered ferrite core of nearly any shape and frequency
- the traditional pickup has little effective shaping of the magnetic field path
- guitar pickups are not optimised to a point where they are readily used elsewhere in other sensory applications and devices as economy of scale should dictate in an open and manipulation free market... I don't think they are anyways
- what might be the result if a 270° toroidal powdered core were designed and shaped for each string while tailoring the copper winding and ferrite for each string's mean frequency and shielding each of these
- would a chord segment gap in a toroidal core pick up more 3d motion from the string
- what effect would a primary and secondary winding wound in the opposite dot notation direction have on the pickup of more complex harmonics and motion
- why does none of this matter due to the filtering of LCR and the noise floor or other aspects
Like here is the basic range of commercial products:
The typical schematic of operation:
Basic construction:
This is a typically low noise toroidal transformer that has been around for ages:
Now I need you to abstract this concept with me a little bit. Imagine if a small toroidal core was below each string and offset towards the neck or bridge so that they will fit. Nothing would stick out or surround the string. The 270° is not a radius cut like a pie. Instead it is a chord and removed segment:
There are totally random pics from DDG that are somewhat illustrative in abstract:
These are just some random powdered core ferrites that illustrate how these can be formed into any shape now:
I usually avoid anything audiophile related because it draws out pseudo science nonsense like crazy, but at the center of this question is really a desire for a deeper understanding of sensors and magnetics that have much broader applications in precise motion control and sensors for a range of equipment.
In a higher level of abstraction, I'm also really asking when and where does this subject become the realm of the illusive bearded nude virgin demigods that get enslaved to corpo NDA masters from birth. ^.5^/s
(47m/8b) × 100 = 0.5875% of the world. Those numbers are likely total accounts as well and nowhere near the real active users. I bet many of these are also systems with multiple users or users with multiple accounts. Reported numbers are usually unverified and inflating them as much as possible is in the best interest of Sony on may fronts.
It is neither here nor there. I used to love the first few generations of PS stuff, but I really see no reason for consoles like these any more. I owned everything I played back then. I find it rather pathetic that my right to own has been stolen.
I'm presently taking a snack break from Cataclysm DDA after tracking down foods with better iron content in the game. Under that I have a bash script and Emacs running with my mods to the game. I've been playing all afternoon and making little odds and ends for the game. Sorry if my perspective from a non dystopian space rubs the wrong way. What I'm doing isn't for everyone, but if everyone had some better self control and the character to stand up for themselves, you will find that you get your rights back from these asshats, or you will get them from the next generation of platforms that rise from the ashes. The only terms that actually matter are the ones you're willing to put money into. I back up that statement. I'm on a 12th gen Intel with 16 GB GPU. I would be playing AAA titles but there are no game manufacturers. I don't care if I'm the only person unwilling to adopt feudalism and serve some tyrant overlord on their yacht. So be it.
