I was thinking it would be nice to have a sound notifier during the roast to remind you to log temperature on a curve. Maybe you can adjust the frequency of the timer to notify you every 30 seconds, 1 minute, or etc.

When i was roasting last night, i was trying to read a book while roasting but i constantly had to check the timer to see when the next minute will hit to log the temp. if a beep or ding sounded every minute (or adjustable interval you would set) i could read or do something else and just hear for the next beep/ding/sound. obviously the purpose is to not completely walk away from the roast, but not keep my eye on it the entire process.

let me know what you think!
