Today I'm doing a USB cable test.
I have quite a few to go through

You know a USB-400 cable like this is better than USB-C, because 400 > C -

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 25-Feb-2024 09:47:23 JST Foone🏳️⚧️ also I'm using this device in the CR2032-powered 3v configuration, right?
I own at least one cable that works at 5v but doesn't at 3.3v... because it has some smarts in it, and they don't run at 3.3v

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 25-Feb-2024 09:47:24 JST Foone🏳️⚧️ ahh, one of those famous three-wire USB cables.
GND, VBUS, and D+ are connected, D- isn't. I'm sure that'll work fine -

Foone🏳️⚧️ (foone@digipres.club)'s status on Sunday, 25-Feb-2024 09:47:24 JST Foone🏳️⚧️ also this tester can tell if a USB-C cable is inserted upside down or not.
I kinda hate having this ability -

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:40:39 JST Foone🏳️⚧️ my wife randomly found a cable in the bedroom, and I ran off with it to stick on the tester. Guess what? It's a USB-C charge only cable!
We must stay ever vigilant, the threat never ends.

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:40:42 JST Foone🏳️⚧️ and one cable has defeated me:
lightning to micro-USB.
Normally I could do the same trick I did with the micro-micro cable, but in this case, the cable is too short for that. Since I don't have any USB-C or micro extension cables, I can't make it reach

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:40:45 JST Foone🏳️⚧️ okay all done. Let's see the count:
1 power-only mini-usb cable
1 power-only USB-C cable
4 bad cables
3 magneticly attached cables I'm throwing away because I have lost the other halfTWENTY FUCKING SEVEN power-only micro-USB cables.
All have been beheaded and can now be thrown away.

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:40:47 JST Foone🏳️⚧️ Or these USB A to micro connectors, which are supposed to be switchable between power-only and data+power.
ONE of them works, the other doesn't. It only does power, and windows throws up a "USB device malfunctioned" error when you try to switch it to data mode
(unfortunately when I connected them both for the picture, I forgot which was which)

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:40:53 JST Foone🏳️⚧️ okay so it seems that the way this device works means that it's always going to run something like 0.5v across the cables. So no matter how I power it, cr2032 or VIN, it can't test my couple of cables that need +5v

like, people are always saying you should never make a male-to-male power cable... but no one ever said I shouldn't make a male-to-male-to-male cable!

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:41:16 JST Foone🏳️⚧️ that one has all the data pins connected, so unlike the usual kind of 3-end connectors which are just there to get some extra power for external devices, this one will break a lot if you connect all three ends

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:41:25 JST Foone🏳️⚧️ and the frankly surprising number of cables I own which have more than 2 ends.
usually they're like usb 3.0 micro B to usb A and an additional power-only usb A, but sometimes they're like USB A to usb mini to usb A female

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:41:33 JST Foone🏳️⚧️ okay all "normal" cables tested. I'm now into the realm of tricky ones this can't test directly.
things like male-to-male micro-usb.

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:41:36 JST Foone🏳️⚧️ I decided to cut out the middleman and test all my USB extender cables at once.
Good news: all eight of them work.

Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 29-Feb-2024 03:41:40 JST Foone🏳️⚧️ ooh, nasty: I found a USB-C cable that consistently has a disconnected D+ in one orientation, and intermittently in the other orientation.
So it only works <50% of the time. Nasty.
