The "pup" in the comics below is Florence a Bowman's Wolf (uplifted wolf species). She's as intelligent as a human.

I agree with Chris's dad. Especially given that it's a mobility device *with communications*. Killing the comms when there's a fault in the drive system is an *insanely* stupid decision.

What stupid design decisions have *you* had to deal with?

*Gah!* Yeah... I've encountered designs that challenged my vocabulary. When it's that level of stupid, I start swearing in Klingon. [lovely language for that, you can say exactly what you mean and have it sound just dreadful!]

My solar system has a similar problem... the charge controller module requires a certain amount of power to work, if battery it's charging runs too low, it shuts down supply to prevent damage to the battery. Which kills the power to the controller module, so when the battery voltage then picks up because it no longer has a load on it, the controller module turns on, and turns on everything else because the voltage is now above threshold.

Result.. the lights turn on and off repeatedly at an ever slower frequency as the battery runs down... thus defeating the whole purpose of having low battery protection.

In addition, if the battery is flat, or stuck below the critical voltage threshold, the charge controller won't switch on...which means, in the morning, it won't charge the battery up!

I had to build a by-pass circuit to charge the battery bank directly from the small solar panel, but only if the charge controller is off. [which wasn't actually too difficult and should've been part of the module from the start!]

Yeah... designers just don't think about these things. Lack of joined up thinking I call it.

Like washing machines that require you to clean the water jets, otherwise they clog...but there's no easy way of actually getting to them to do that! Had to disassemble half the damn machine. Or a reset button on the integrated PSU/UPS... which sits at the back of the server rack, against the wall. [great idea in principle, but that damn reset button ruined it.]

That's one of my favorite comics. Florence is more intelligent than most humans. She's an engineer. :-)

Also: Don't get me started. :-)

... Wait. Killing the comms when there's a fault in the drive system? That's the last thing you'd think anyone would do! The heck?
