Since when is Uber a "well-known troll website"? (Oh wait, that was a

security fail, not a DDoS...)

Right, because I wasn't talking about Uber.

Hehe. I know, but Uber did have a breach as well, and they were remarkably transparent about the mechanics of the attack.

I wonder if Uber could be compromised in a way that would turn the fleet into a flash mob. That would be cool.

I finally got around to restarting "the elevator panel project." When my son was pretty young his grandfather gave him an old Staley elevator panel that had been harvested from a modernization project. About six years ago I added an Arduino and a numeric display and I turned it into an elevator simulator. When everything was ready and working, two things went wrong:

1. I fried the Arduino while permanently soldering it into the project
2. A series of bad mistakes lost the code.

The damn thing has been sitting on my desk for years. My son is still fascinated with elevators (and trains, and other things) at age 24 so I'd better get around to restarting the project. So I brought it down to the bench and started a rewire with a fresh Arduino and a socket for it with screw terminals so I don't burn the damn thing out again.

The buzzer always sounded kind of lame powered directly from the GPIO so I rewired it through a 3.3K resistor and a 2N2222 transistor. It sounds great now. Once I get all the buttons wired back in and the lights and the display, I'll have to rewrite the code. Not a big deal I just have to do it.

All of this was just a build up to say that it felt damn good to be at the bench soldering a transistor. :)

True, but I have a couple of Arduino Nano boards left and this project doesn't require a network attachment. ESP32 does seem to be the current hotness since most projects *do* want a network connection now. Those have an Arduino-like programming environment, right?
