Really good side glow fibre optic

I built a little add-on board for the AVHzY tester and wrote a program for testing cables and grading 1-5 based on cable length you enter plus resistance it measures.. Here's a YT video - build link to schematic in the description - https://www.youtube.com/watch?v=sXJaRawVfYw&

Could it be that the mystery chip automagically handles higher voltages? You could connect it to a 9v battery and see what happens!

I was impressed at its features, you can plug it into your laptop and see everything on the big screen too, not had chance to play with it properly yet but so far it's great (not sussed out how to connect it to my phone via bluetooth yet. That bit has me stumped but I can't find anyone else having the same problem so it could be a faulty unit or my phone is too old [Nokia 8])

They're not that expensive for the features they have.

I recently bought a FNIRSI <--(COMPANY NAME) FNB48S 'USB Voltage and Current meter'. It has all sorts of monitoring and graphing functions including lead resistance testing. i had to hunt but got one from ebay for £30. It has USB A, Micro USB and USB C connections. *Not a sponser lol

USB testers? Is this some inexpensive device for perhaps under fifty dollars? I got some USB A and micro connectors which allow me to measure the connector to connector resistance within a fraction of an ohm. My results haven't been encouraging. To get the resistance low I had to make my own cable. 😡

Consistent intensity along the full length.

Some USB testers will actually measure the resistance of the cable. There's a huge variation in charge current between leads.

Big Clive

It does have all four connections. That does pose the risk of a smart charging system negotiating a higher voltage, which would probably nuke the circuitry.

Big Clive

The RGB ones aren't so great for fibre optic use due to the three chips being offset from the centre of the lens. The light tends to be projected out as three beams at an odd angle.

One day I happened to have a charging cable near a small magnet and it stuck to the cable! I started to investigate and found that the cable was made mostly of steel. I've found that the reason why it takes so f'ing long to charge is the resistance of the cable is too high. It's a combination of thin wires and the wires are not copper. :-( I would appreciate it if you or some other channel (Diode Gone Wild?) Would tell us if a cable is good or bad for charging. Does anyone know if this has been done? Thanks, Clive.

One thing I wanted to ask is if this is a "charging only" cable?

Shame they chose 3 flashing LEDs like that. If they were replaced with the slow change RGB LEDs, I think it'd look nicer.

Quality products from Pound Land ? has their QA become complete shite ? You pay for dubious and and you get kwality .. groan

By linearity, I assume you mean constant or consistent light?

I like! Sadly, the nearest OneBeyond is rather a long way from where I am.
