Cool feature for runners

[hrdcorbassfishin]

For me, I would prefer not to carry a stopwatch when doing HITT (high intensity turbulence training). If it would be possible to have a feature that is a stopwatch that you can set intervals for a loud beep sound. It would decrease the volume of the music playing and beep really loud at, in my case, at the 5 min mark, 5:30, 7, 7:30, 9 etc... of course those intervals would be customized to your own needs.

For those who run steady pace and want to keep a 6min/mile pace, you could set beeps at like 5 min and 5:30 so you know if you need to push harder to stay on track.

Anyway, Ithink this would be very useful and would love to see it in a future release. Anyone have any thoughts?

Hey I like that IDEA!

related, but not all that similar, I run 10 min and walk 1 min, so a linked timer would be great.... set timer A for 10 min, when it counts down to zero, Beeeeep, beeeep, then start timer B (which is set for 1 min), when it counts down to zero, different beeeeep beeeep, then repeat back to timer A!

I wonder if this could be done with Lua to run in the background with listening to tunes or audiobooks...?

Hi, I posted a patch to allow Lua to beep.

I'd be glad if you could test it.

Code: [Select]

rb.beep(freq, duration, amplitude)

I wonder how we can wait x seconds efficiently. A pure empty loop + os.time() checks would IMHO grab the CPU's time, while using rb.sleep(rb.HZ) does not let us stop the Lua script exactly when we want.

How about it the mic picks up your footsteps and beeps to increase/decrease pace? Maybe have  Gunnery Sergeant Hartman shouting at you

Just place a small sleep into the loop. ie rb.sleep(rb.HZ/100) would sleep for 10ms.

Indeed, but hrdcorbassfishin and jgsprenger wanted more time ("at the 5 min mark, 5:30, 7, 7:30, 9 etc..." and "run 10 min and walk 1 min").
Maybe sleeping 60 times one second would save some CPU and allow us to act on the script more often. But maybe that's what you meant...
