For Morgan Jones - I can't find where he posted the magnet coils experiment...
Smartphone sensors are a lot better than you might think

Here is a smartphone magnetometer made by Bosh. I believe that Apple uses a custom version of this

Get well soon Phil, we need you

Have you tried the magnetometer in a smartphone? Plenty of apps can display its readings. Mine reads to 0.1uT

Sorry for the hijack

Good progress and looking forward to seeing the results. On the subject of stuffing, don’t know if you have seen this test:

Something I keep meaning to do with mine…

I can’t be the only one with a mess behind the TV, but it looks excessive to me

Not a laptop, but could run headless (once set up) and VNC/RDP/whatever into it

DIET. No, sorry, Win 11 only

Neither, it’s 7 years old, so intel
Hmm, don’t know if it would work on Apple silicon

I run Windows XP on a MacBook Air using VMWare Fusion I think. Not with it just now, so can't check
Don't see why it wouldn't run Windows 7, but don't know what it does with USB

Wow, you’re not kidding
Enjoying the armchair view of this project, and a bit jealous - live in a flat, so nowhere to build and nowhere to put anything that big

Brian

Those hips though <shudders>
Wonder if they can keep going round like on slip rings

Just had another look at the blue trace, and there's a lot of HF there for a sub
Is the brown (?) line the sub or the blue one? There's not much difference time wise, but just to be sure
Did you test with the crossover bypassed?

Sorry for all the questions, but it doesn't look right - then again, I ...

What are you using for a crossover, and what frequency are you crossing over?

Brian

I always used 0xAA55 mainly because it’s a nice binary pattern, but I suppose anything recognisable would do. No idea if that is more or less likely to appear than any other pattern though - I guess it depends on context

Nice bit of code and bookmarked - thanks
