I can't tell which microcontroller you used, but it's probably more powerful than my first computer!

It's the Atmel ATTINY2313 chip -- the dev boards I'm using are here, and the chip specs are as follows:

2Kbytes flash memory
8-bit AVR CPU
max clock speed of 20MHz
up to 18 pins for I/O

What was your first computer?

An Intel 8080 with 1k of RAM, running at 2MHz, (but taking four clock cycles to execute an instruction vs the AVR's one) So, yours has twice the memory and is 40x faster!

But, I had a paper tape reader!

I'm amused that you're forward-thinking enough to vastly overproviion the hardware of your devices, but not to just put together a few extra boxes while you're already making the half dozen, because, hey, you might lose or break one, or get some more instructors...

It's all about saving time! Why would I want to spend 1/3 more time and money when I could make precisely what I needed? The chances of one getting lost or broken are pretty minimal. And since it was such a simple design, I was able to make the last 2 units nice and quick!

Minimization of effort. I am a lazy engineer. I spent the minimum possible effort to get precisely what I needed last year, and did the same to be ready for this year!

The fact that it was all last-minute has nothing to do with it. At all. I'm sure.

And if I had known I would still be out of work I might well have ended up at pirate swing. Maybe next year - this sounds wonderful.

It's funny, you said something very similar last year! :-D Perhaps Pirate Swing 5 will be the charm.

Aye. If I went I would want to be in the classes track, and i didn't want to commit that far out. Given that I've just been away 11 days and am going away for a week two weeks hence and there is RKO on sat it works out ;)

But yes, I will br missing a lot of fun!
