I've built a few (small) things in Perl recently:

a) iCalendar and timezone pre-processing for an Arduino alarm clock; Arduino libraries aren't up to the task (and neither am I! recurring events with recurring exceptions is kind of complex), but cpan iCal libraries and timezone libraries seem to work.

b) personally monitoring script, checks a bunch of stuff and sends email (well, cron sends the email, really) if problems persist for long enough

c) something to fetch my DSL sync speed and status (uses Net::Telnet), which feeds into the monitor script, but also used to adjust bandwidth limits for fq_codel to reduce bufferbloat.
