I may post some random item from my junk boxes and component drawers I'm sure I have a few ancient items that are worthy of comment too (OC71 transistors with the paint scraped off perhaps).... Postbag circa 1977 I would think. :D

Ah that would be quite cool, sort of like Bunnie Huang's 'Name that ware' -> https://www.bunniestudios.com/

Nothing too exciting in my first rummage, but one or two ancient and strange things are lurking in the darker corners of the junk pile. Refrain from any references to the ancient and strange individual posting these pictures please. :D

The blue board with the switch is a "CY7C68013A board" -> http://www.ebay.co.uk/sch/i.html?_odkw= ... d&_sacat=0

These can be used as a poor man's logic analyser. -> https://sigrok.org/wiki/Lcsoft_Mini_Board

There are a number of variants of this type of board, and they are as cheap as chips. You need to add some buffering if you intend to use them for higher voltages, as the bare CY7C68013A is relatively fragile.

You also need some place to put all this junk useful stuff.

The really obscure and random junk useful stuff lives here...somewhere :? ... one day I'll get round to re-labelling them all.

Portable clutter management relies on lots of theses... two quid each in one of the two near identical discount supermarkets, can't remember if it was Aldi or Lidl... but they were discounted from eight quid each to two, so I bought the lot. :D

I notice it's all in the shed/garage/utility room - seems to be a common thread that our better halves can't stand us having our 'junk' at hand.

What's good for the goose....

The goose also has a fair pile of "stored items", the difference is that those are "useful and we might need them some time", where as the gander's "stuff" was just junk cluttering up the house. :lol:

Dumpster divin' - It doesn't make me a bad person... ;)

I was passing a local skip and spotted a whole bunch of emergency lighting units.

I happen to know that these older style units have something useful in them, namely a bunch of very robust NiCad batteries...

But why on earth would anybody want NiCad when we have all of these fancy schmancy LiPo cells these days? you ask....

Well there are several reasons that emergency lighting and all of the Solar charged garden lights have NiCads rather than LiPos..

They are much easier to charge, and much more forgiving if you deep discharge them. It wouldn't be a good thing if your emergency lighting set fire to the building now would it?

This also makes them ideal for situations where you might leave a solar powered device out in the wild for days unattended, for example a wildlife camera.

They are also good for low power projects where accidental deep discharge might destroy a LiPo.

They can be continuously trickle charges (which is how they are used in emergency lighting) and they are fairly tolerant of high and low temperatures.

All of this build up.. for yet more junk... drum roll... 6V (5 x 1.2V cells) - 4.2A (30 A peak).. http://www.time1.ru/data_sheet/saft/ni-cd/VT_Cs.pdf

And best of all ... the price... free.

I haven't decided what to do with them yet... any stm32f103 related suggestions?

If you are willing to take the risk, you can find all manner of interesting "stuff". :D
This microscope came in to my clutches after peeking in to a similar skip full of junk a couple of years back..
