Christmas lights

[Niels Bohr 72]

The last line.

Well, depends. The MCUs are probably like 20 dollars a piece. You need to estimate the amount of energy you will need. Well, I'd say at most it's $1000. But, when you have built the software, you can probably keep all the MCUs for years to come. Cost thereafter is the energy bill.

Where do you buy this stuff? Where do get the software?

Software is developed inhouse using C++. Very easy to do for a skilled programmer (aka me). I can make a gui interface to build a standard window, and make it handle different signals, etc...Signal Processing, I can use Matlab for that so I can capture the music and do some DSP analysis on it to determine how I'd like to setup notes to switch, etc...Then, I'd implement that onto hardware which is the MCU, and/or the 7400s chips, FPGA boards.

MCUs, 7400s, FPGAs can be bought from Digi-Key.

Unfortunately, I'm not even an unskilled programmer It would be fun to do something like that.

I like to think that I'm still a pretty decent coder (though I've been a management type for about 10 years, I still mess around in Perl quite a bit).

Here's one for ya. Can you guess the output?

#!/usr/bin/perl

my @names = qw(Spooky CMaster BY);

foreach $n (sort @names)

{

print "$n boffs sheep every night\n" if $n =~ /$S/;

print "$n is the resident VJ engineer\n" if $n =~ /$C/;

print "$n is a blowhard twit\n" if $n =~ /$B/;

}

Spooky boofs sheep, Neils is the resident engineer and BY is a blowhard twit?

}

Spooky boofs sheep, Neils is the resident engineer and BY is a blowhard twit?

Close. But there is a 'sort' in my foreach loop. That will sort the elements of the list in alphabetical order.

So the actual output should be:

BY is a blowhard twit

CMaster is the resident VJ engineer

Spooky boffs sheep every night

There is a carriage return (\n) in each print string, so each line is printed separately.

Also, there is a bug in my regular expression, meaning you won't get this output if you run the code as is.

Can you find the bug? No?

Well, the bug is the use of the '$' which I intended to match the first character of each target, but in fact matches the last character.

To match the first character, the '^' is needed,

hence

print "$n boffs sheep every night\n" if $n =~ /^S/; etc.etc.

Yes, I am a bit of a geek. But I still lovez my sheep
