Another fun day in the trenches working on a client to control some embedded stuff.
I wasted about half a day dissecting log files, seeing the scale move the way it was supposed to when the machine was dispensing product, only to crash back down to around the starting value during the let the scale stabilize/last drop fall pause, and going WTF how is that happening.
The root cause turned out to be that the recently arrived box 2 is on a wobblier table, and/or has vibrateyer mechanicals, and/or a more vibration sensitive scale by a combined factor 15x!! vs box 1 which we'd done 99% of our dev/testing on.
Box1's peak scale jitter turned out to be ~50 during the setup phase (and typically only half that), which is small enough relative to the hardware's control elsewhere not to matter. Box 2 was regularly swinging 500-750, enough to totally fubar an operation dispensing only 375.
Adding insult to injury, it didn't help that the 2 cases I dissected in the logs both had due to apparently malicious coincidence a jitter peak that ended up reaching to roughly where the dispense operation was supposed to end up. If it ended up spiking to double and dropping I'd've been more likely to catch on without burning so much time.
On the whole it's been an interesting project, but there're days when I wish I hadn't found the effort to gnaw through the restraints when the alarm went off in the morning.

I had a similar experience about 30 years ago.
The Israeli Meteorological Service had some gadget that recorded the UV level coming from the sky in all directions, sending it as analog data to an A/D converter, which then fed it into a PC for processing. I wrote the processing software, everything worked fine and we got clean graphs of the UV levels.
A few days later, I get an angry call from the project head. Apparently, everything had gone FUBAR, and the data were garbage.
To cut a long story short, it turned out that one of their engineers had added a recorder in parallel to the A/D converter, so as to record the original analog data. The recorder was not electrically isolated, and added enough noise to the data to make it meaningless. Adding an opto-isolator to the circuit solved the problem.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

Very cool story and solution. 
Really interesting.

Actually, you have a great story that illustrates real engineering issues. In the embedded world (I live there too), there's just too much weird s*** to break your code. I happen to work in packaging (think bottles running down a high speed line). One thing that always has to be handled is when the line stops, it almost always shifts back a little. There are a hundred other little *real* things that will render your elegant solution a bubbling mess of debris...

A wild hamster runs a few miles every night to gather their stuff. They are not made to sit in a cage all day without any way to get rid of their energy.
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

reverting to basics I always thought the idea was to poke them with a sharp stick, optionally roast over a fire, then eat them in order to get energy.
Is wasting good food on a "smart" phone really smart?

As any cat can tell you, rodents are not the best way to fill your belly. Even the cat needs to catch eight of them every night. You probably need a few more. The only good thing is that they seem to reproduce so fast that there are always enough of them to catch.
Letting the hamster do some work actually is one of the smarter ideas for a smartphone. One full charge at the price of a small bowl full of sunflower seeds. I have seen worse, but that's probably because the phone was smarter than the idiot that used it as a brain pacemaker.

I've got 14 hours before getting on the road for a 6 hour road trip for a tradeshow. I haven't begun to pack yet, but am still screwing around with some of the test data and getting all the last minutes updates posted. It's going to be a long weekend. 
Did I mention that I really hate tradeshows?

I wouldn't want to be in a booth but I don't mind walking around and checking them out.
You know you've sort of made it when someone sees your name tag and won't let you see their stuff. 
-edit- what I meant by that was I was with a start-up once with only a few customers and this one (rather big) company had heard enough about us to consider us competitors and they wouldn't let me in their booth. It was rather inspiring at the time.

You can hire one of our motivational trainers if you have such a hard time. They will motivate you to go to your tradeshow in no time. And you will like it. You can choose between several different trainers, depending on which kind of motivation works best for you:
1) Sanctimonious moralizing priest (almost obsolete nowadays)
2) Drill sergeant, 20 years experience. The classic.
3) Nagging wife, screaming kids cost extra.
4) Nervous boss. Does not know what she wants, but wants to have it right now.
5) Bossy boss. A perfect micromanager and remotecontroller.
If you already have some of these at home: They are amateurs, not the kind of professionals we will send you.

I have the equivalent of (1) at the synagogue, A few (2)s (in the reserves) at work, (3) at home (incl. screaming teenagers), and (4) and (5) all around me.
I think that I have all the motivation that I can stand.

Then you must be glad when you are allowed to escape to a tradeshow.

I feel sorry for you.
I've spent more than enough time on the booth at trade shows to know that I never want to do it again.
Recommendations: Good comfy shoes - not new ones, you'll have blisters in hours and trench foot by the end of day 2.
Expense account. It is possible to empty a hotel of good quality red wine. I've done it.
Take a lunch - if you ask nicely, the hotel may provide - and keep it in the back of the stand where you can grab a sandwich or similar quickly to fuel up between visitors. Much simpler that trying to eat the venue food, because everyone will be queueing for that at the same time (and it's normally crap anyway). No beer until the show closes, but coffee is a good idea.
Make quick notes as soon as a visitor leaves - you won't remember what they were interested in when you get back to the office, particularly if your stand is busy.
Get contact info back to the office ASAP: if you can have relevant info on their desk when they next get back to it, it reminds them who you are, and makes the chances of a follow up interest much higher.
Eat a big breakfast: you use a surprising amount of energy standing around!
Good luck - and enjoy yourself as much as you can (you have my sympathy)

By the middle of the first (and longest) day of the show, my heels were getting raw. After a couple of hours I resorted to stuffing a cardboard coffee cup holder into my socks...currently with band-aids on both heels. 
It was a half-day show yesterday, then packing up and driving 6 hours back home. Now spending the day (Sunday) tweaking a new product based on customer feedback. My business partner stayed behind to visit family and will be spending the next week travelling between customers to get them setup and working with it. The fun never ends!

Been too busy to respond but finally back home. Part of the problem (lack of motivation) is traveling with my business partner of almost 20 years who is somewhat ditzy and tends to complicate everything. (nothing is ever easy) Example:
