How about mentoring a project? You can support up-and-coming new SDR
hackers, teach wisdom and promote projects you're enthusiastic about.
Mentoring *is* some work. But it's also lots of fun! So think about if
you'd like to mentor, and sign up next summer
ignal at once, and make your block a gr::sync_block.

yourself. Make sure you don't set relative_rate to zero, again!
In a sync_decimator, you won't need forecast() at all and your work
function is much simpler. The scheduler will also never try to call a
sycn_decimator w/o input.
