I really don't know where all this memory goes.  Sure, my old 32k BBC Micro was a bit short, and I recall the 640kb PC limit being a bit of a constraint eventually, but there must have been a point somewhere in the hundreds of megabytes where there was enough memory for normal folk.

Also..   as a serious question,  what do people do with Arduino ?

It seems to be an entry level programmable PLC..   is it just that,  and a toy thing for teaching kids how to make a robot pull wheelies,  or is there actually a business purpose for them ?

I guess I just imagined that a business would use full Siemens / Allen-Bradley type systems.

What does Mr Pin do with them ?

he's put controllable valves at key points in the local waste water pipes and can flood any neighbour at the press of a button

I reckon they're mainly educational, entertaining, maybe suitable for embedding into small, specialist production runs or for general tinkering.

I built a USB head tracker with one. The people who designed it and wrote the firmware have set up in commercial production, which is good to see.

Not sure there's a business purpose in the "industrial controller" sense of the thing.

Aargh. Actually I run several virtual machines. I didn't replace the original 16MB as these are under the keyboard, and therefore a right pain to get to. I bought this glofified games machine in a previous employment, where I was simulating a ship's IT system.

They are a great toy, and add on boards are available for nearly every purpose. Wow! I wish these things were available when I were a lad.

I do quite a bit with Arduino. The 'brain' of the thing or different variants of it is embedded in all sorts of consumer electronics, the Arduino board just packages it in a convenient way for you interact with it and provides a convenient interpreter and development environment to make it hobbyist-friendly. Plus they're dirt cheap so you can piss about and if you blow it up, just get another one for a few quid.

So yeah, it's both a 'toy' or learning tool for young 'uns to learn both electronics and C-ish programming language, but you can actually do some pretty complex stuff with it. I use it both for personal projects and in an industrial R&D setting.

I love it. For me it helps to have an actual task I need to solve with it rather than just aimlessly tinkering.

Going to get one of the Teensy boards for my next little personal project

Dirt cheap @Boglet. I just been counting all the bits, around £30.

Now I am awaiting my MSF receiver so I can get the time from Cumbria. There is a real time clock module in my kit, which will be far more accurate than the computer clock.

I mean proper dirt cheap, I bought a bunch of non-genuino chinese Arduino nano clones for about £2 each.

I know. I probably paid more for the nice plastic case than the contents. The Nano is a bit short of IO. So I have the Mega2560. There's nothing non-genuine about a Chinese clone, as the hardware and software are open source.

Well, they use a chinese 'clone' USB-serial chip instead of a 'genuine' FTDI one but yeah, basically zero functional difference.

I always liked FTDI serial chips, because they always work, unlike some others I could name. I am surprised they are Scottish.

They did some arguably very very shady stuff a while back, bricking devices that misreported themselves as FTDI devices.

Bit of a dick move, even if I understand why they did it.

As mentioned elsewhere, I have 2GB RAM, just replaced old 70GB hard drive with 120GB SSD, have 1TB external for files etc.

It seems to do me.

Yes, a modern tablet is good enough for most uses.

The time in Cumbria is 1837. I always has been, since 1837.

I've moved to esp32* -- they're dirt cheap, include wireless coms (of various sorts), are suitably low power and are powerful enough to do things like real-time Fourier (well, I do Hartley transforms as I don't need phase info).

The modules I use for dev (Heltec - less than £10) also include a small oled display, which I don't actually need for the application but are really useful for displaying 'as you go' information that helps with debugging.

For ultra low power stuff I still use msp430, as they don't actually appear to use electricity.

Blokes who don't have MSF capability are poofs.

I have two MSF capable watches...

Here they all are with reference to Radio 4's "pips" at 12 noon today...
