Treadmill (desk) needs speed ramps and intervals

I continue to love my LifeSpan TR1200-DT3 treadmill, since 2014.

At first I could only walk slowly, 1-1.4mph, while working.

Then, a year or so ago, I started being able to hit 2-2.5mph for some tasks, like email triage.

Recently I have started being able to run >= 4mph, typically while listening to "XXX Update Meetings", where I don't participate, and often don't need to take notes.

But... sometimes I need to take a note, and may need to slow down.  Not suddenly stop, but ramp down safely. 

(Stopping suddenly can be dangerous - I have twisted my knee several times when the emergency stop engaged.)

PROBLEM: the LifeSpan console changes speeds in clicks of 0.1mph.  Having to lean over and click 20 times to ramp down from 4.0 -> 3.9 -> 3.8 -> ... -> 2.1 -> 2.0 mph is inconvenient, and somewhat dangerous.

WISH: 2 or 3 speed buttons, with designated speeds.  And a smooth transition between them, not instantaneous.

EXTRA WISH: I sometimes do intervals on my treadmill desk, while listening to such meetings. 20 clicks to change speed is a pain.  After the 2 or 3 speed buttons, programmable intervals, would be nice.

DIY: yeah, I should do this in my copious spare time. There's a small community of folks who have made their own treadmill controllers using Arduino or Raspberry Pi or the like.


BTW, one big reason why I did not start running fast earlier was not my fitness level or even my sense of balance, but that I have had trouble adjusting the treadmill tension: if it runs smoothly at 0.4 mph it slips at 5mph, or it binds at 1mph when smooth at 5mph.
