@ mnementh,
I just love all singing and dancing watches as my main goto watches but every now and then a nice dress watch is OK too and yours fits that bill nicely.

As an unsociable bugger with children that can’t not talk all the way through a film I tend to go on my own on Friday mornings when there are literally zero people in the cinema and it’s £6 a go. Joy to being on a contract break now with freedom to schedule my own hours. Did deadpool 2 a couple of weeks back :)

I’m amazed at how much integration you can get in a watch now. The LCD screen equipped smart watches I feel are cheating. That’s pretty damn cool that one. I don’t do watches any more though myself. Just never have a need for them. Plus the phone does the health stuff for me passively.

I’m collecting 3d printer points at the moment. Whenever I see a disaster it’s -5 and whenever I see a nice setup it’s +5. When I get to 50 I’m going to buy one and work out where to put it later. That’s a +5  :-DD

That is my general feeling towards watches as well; though after 42 years as a "gainfully employed member of society", most of it as an hourly wage slave, I have grown accustomed to something being there and feel a little naked without. For that, the Shine serves very nicely; it serves an important purpose (helping me make sure I exercise more), it weighs almost nothing, and if I need more precision in a timepiece than it can provide, I need to give up being semi-retired. Or reach for my big pocket watch. ;)

Don't worry. Either it will need fettling, or you will invent a reason to fettle with it.

After all, you have TEA/GAS/etc, and it is a 3D printer.

...and there's the 2020 all done; took 40 minutes. The slubs were purely superficial; rubbed right off. Filament is Inland PLA+; settings on the Tevo Tornado all stock, printer is bone stock out of the box. I'm gonna call that pretty fettling close; time to make a spool holder.  :-+  I think I'll use the purple this time.  >:D

bd139; that should be a solid +20 now.  :-DD

I bought a couple of the cheap Android smart watches; they require too much charging, constantly do the wrong thing due to too small a touchscreen, and the only really cool thing about them was that my 2nd one would actually serve as a standalone cellphone with Skype video chat. After wishing for one since I was 8 years old, I FINALLY have Dick Tracy's 2-Way Wrist TV. ;) The shameless scifi nerd in me of course is all kinds of proud of that; in the same way he's proud of me finally having a "pocket laser" on my person, and a green one which is actually capable of doing some physical damage at that.  :box: :-+ :-DD

But yeah; the Command is first a nice dress watch, and second a marvel of miniature robotics with fitness tracking. The nice thing is that they held true to that aesthetic from beginning to end and did not compromise on it; a truly rare accomplishment anymore. I just discovered while watching some of the longer adverts that on top of all this awesomeness, it's supposed to have a year battery life!  :wtf:

The "all singing and dancing" was not a reference to so called smart watch  :wtf: To me that means a smart and clever watch that offers sensible things that a watch should do and do very well without needing to partnered by a bloody phone, or a plug in charger, nor should it need to be charged on a daily basis.

It needs to be a good timekeeper, automatically adjusts for different time zones, stopwatch with lap timer function, slide rule (in case you ever feel the urge to do some maths and your calculator is at home and your smartphone has a flat battery), have a power system that never needs a battery replacement because its solar powered. :-+

A watch thats tied to a smartphone isn't that smart after all  :palm:

Hey ho. Been playing today. Back at university I was basically a dick through the entire control theory stuff with the intention of “skipping that shit and hanging around in the digital domain with the cool kids”. Turned out that was boring and I was an idiot. Oops. So decided to drag myself through the Learning the Art of Electronics chapter on the matter which consists of building and tuning a PID control loop. I’ve built PID loops before but did not understand what he hell I was doing and went for trial and error rather than understanding phase margin etc. Book is extremely enlightening.

Uses a simple Alps motorised volume control as the “plant” and a diff amp, integrator and differentiator summing into a motor driver to kick it off. Pretty good fun it was. Really like the book. Considering running through some of the earlier stuff to see what I missed. Have an application for this: a 2m antenna rotator!

TEA? Well it’s an excuse to exercise the 6237B and the Rigol which are wonderful for this. The rigol allows rolling display at 1 second per div, depicted below and the HP due to the analogue metering allowing quite a lot of current damping (not depicted but it’s up on the shelf).

Yes it’s a rats nest and yes it’s on a solderless breadboard. Highest frequency here is less than 3Hz though so meh :)

Now to camp on eBay to find more toys to play with. Problem doing the above is it drives the kit purchasing addiction hard.
