small side project from two weeks ago: a microSD "flash memory necklace".

This was the first time I tried the assembly service of the ubiquitous chinese budget PCB company - designed in an hour on a friday afternoon after a conversation with a colleague, ordered the same day and just a week later I had 50pcs in my hand. It's insane.

I will not protect you from the pain I know well.
I will not warn you of the brokenness.
I will smile and be joyful,
I will stop and sit and
be wracked with sobs.
I will be honest, if you ask.
And if you pay attention.
And I will offer my hand, my shade,
and my knowing shoulder.
But I will walk with you when I am able,
when you find yourself where I have stood
on the valley floor
and on the way up that mountain pass
as you search for home.

A friend's analog camera battery ran dry in an unfortunate moment and it's a vintage battery format that's a little hard to come by (and expensive!). Luckily being a 3V battery the 3.3V almost any microcontroller board can supply is perfectly in spec so some tinfoil and two cut jumper cables later another USB-C powered gadget has come back alive 😉

My head hurts.
I just realized that you can build filters for radio out of knotted wire. And you can directionally and phase-tune elements that way too. Like... part of me knew that, had seen that when building radios before - that you don't actually need a core material (other than air or fr4 or whatever) for inductance and reactance to happen. That you can etch filters just by shaping copper in circuit boards - and you can also build complex capacitors with just multi-layer circuit boards. And like... yagi and j-pole and phased array and hoop antennas do work quite well.

But then I was playing with tying some rope, found a pretty knot and started thinking about chirality of knots tied in-place on multiple strands. And somehow ended up here. Thinking about uhf and microwave band tuning stuff, but built big enough for hf problems.

My mind it wanders. too boldly by far.
