  1. Zeo sleep tracker
  2. Every morning I write down on 2 index cards a number 1-5 about the previous day, mood/productivity and creativity.
  3. Then I write down my weight on the scale.
  4. a window-tracking daemon (arbtt) records computer time as spent on various windows
  5. I do spaced repetition every day, which produces some numbers which could be useful for QS, enforced by Beeminder.
  6. I'm currently doing a dual n-back/nicotine experiment, which produces another 5 numbers, also enforced by Beeminder

#1-3 is very easy, a few seconds at most when I go to bed & wake up. #4 is no effort to do after the initial setup, since it is run by a cron job. #5 is more work but is a years-old habit so really not a problem. I struggle with #6.

I lose my pedometer a while ago, but I plan to order another one in a few days, which I will add to #1-2/the index cards. Other than that, I think this is a sustainable routine and useful for future experiments.

Are Zeos worth the price relative to other similar things? I've started using Sleep Cycle, and while I don't expect it to be anywhere near as accurate, I don't know if the difference in accuracy is worth ~$250.

Apparently the current product most equivalent to the bedside unit I use is the Zeo Sleep Manager Pro which is ~$90. I don't know how accurate it is compared to Sleep Cycle: I think some of the Zeo papers compare with standard sleep accelerometers but it seems like every cellphone accelerometer product (there are tons because it's so easy to write) does things a bit differently.
