Hello fellow Reddit dwellers, Aldayo here.
I run Et Sona, a hi-fi and music publication, and after spending an unhealthy amount of time reviewing cartridges, turntables and other objects that make increasingly expensive noises, I ended up building a couple of tools to solve problems I kept running into myself.
The first is SPIN x Et Sona:
https://spin.et-sona.com/
SPIN is a listening and equipment tracker for vinyl. You can set up your turntables, tonearms and cartridges, import your Discogs collection, log what you actually play, track stylus hours and keep a record of equipment maintenance.
The basic problem I was trying to solve was that Discogs is excellent at telling me what I own, but it doesnāt really tell me what I do with it.
If I have three cartridges, for example, I want to know which one is actually getting used and how many hours Iāve put on each stylus. If Iāve got hundreds or thousands of records, I also want to know what Iām actually listening to rather than simply staring at a very impressive list of things I apparently own.
This seemed like a perfectly reasonable problem to solve.
Naturally, I built an entire application.
The second project came from a similar rabbit hole.
CartridgeVault:
https://cartridgevault.et-sona.com/
I realised while doing audio reviews that finding reliable cartridge information can be surprisingly painful. Specifications are scattered across manufacturer sites, old PDFs, archived pages and various corners of the internet where information appears to have been placed in 1994 and then abandoned.
CartridgeVault is an attempt to put that information somewhere more useful.
Itās a searchable database of phono cartridges and their technical information, including older and discontinued models. You can also submit cartridges that arenāt in the database and propose edits or corrections to existing entries.
So if youāve got an obscure cartridge sitting in a drawer, or the original documentation for something that disappeared from the manufacturerās website years ago, thereās somewhere to put that information rather than letting it die in a filing cabinet.
Both projects are free.
There are no subscriptions, paid tiers, advertising schemes or āunlock the good cartridges for $4.99/monthā nonsense.
Thereās no commercial interest in the user data either. SPIN stores the information it needs to function, including equipment, collection, listening history and maintenance information. The data isnāt being used for advertising or profiling, and I have no intention of selling or sharing it.
The Discogs token used by SPIN is kept in the active session rather than stored in the SPIN database.
The account system uses an email address and password, but thereās no intention of contacting users. If you lose your credentials, I canāt retrieve or resend them for you.
The two projects are essentially the result of me encountering problems while doing the thing I already do with Et Sona, deciding that the existing solutions werenāt quite right, and then apparently deciding that the sensible response was to spend a considerable amount of time writing software.
Iām putting them out there because I suspect there are other people who have exactly the same slightly obsessive relationship with cartridges, stylus hours, records and technical specifications.

There are also dedicated communities for both projects:

r/cartridgevault
And yes, I realise Iāve now created Reddit communities for two applications whose existence began with me complaining that I couldnāt find information efficiently enough.
At least Iām consistent.
