I need to find a wireless connected scale to measure objects, none of them very heavy. The scale needs to have an API with which to retrieve the weight readings. For various reasons, including system compatibility and short timescales, I'd prefer to use the Fitbit Aria if at all possible. However, it looks like the minimum weight for accurate readings is 9kg. Can anyone tell me anything about how accurate the Fitbit Aria is *in practice* for weighing items lighter than this?
I’ve been told that my productivity at work needs to improve, and that I should think up three ways in which my manager can measure my productivity and its improvement. Difficulty level: software engineer. Wall of snowflakes inside (longer than expected, sorry folks!) [more inside]
I have to replace a screen/storm door, and when I measured it, it was 80" x 33 1/3". That's... not a normal size, is it? How do you buy a new screen/storm door when the size is so wonky? They seem to come in 32" and 34" widths, what should I do? [more inside]
I've never been very good at either math or at eyeballing things like weight or dimension, but was thinking recently about how to more or less accurately weigh things without using a scale. What good methods are out there to approximate other kinds of measurements? [more inside]

I am a science teacher creating a professional development workshop for other science teachers. The topic is along the lines of "getting real scientific data and measurements from the web for your students to work with". The goal is to find "real" scientific data from the world beyond the classroom, that might make for more compelling classroom activities and investigations in high school and middle school science classes, such as biology/ecology, earth sciences, astronomy, physics, chemistry, etc. The data can be in the form of videos or images to be measured and analyzed, or raw numbers to crunch, or whatever. The data needs to be freely available on the web. Examples inside... [more inside]
i am trying to measure the vibration of a bearing, which is at one end of a simple fan shaft. the fan is large but rotates at reasonably slow speed. fan diameter approx 3m, shaft speed approx 145 rpm, 2 dodge s2000 bearings. i am getting FFT data but when i look in the low frequency range the data is not meaningful. i am using sample rate 4096 Hz, block time 0.125 sec. 20 sec sample time and i think the acceleromter is set up correctly. where might i be falling over?
How do I, using common household tools and objects, determine the (variable) RPM of a fan? [more inside]

I recall something that I believe I heard Carl Sagan say either in an episode of Cosmos or in one of his earlier books, that one could store enough information to hold an entire encyclopedia by putting a notch in a stick, if only one could measure where the notch lies to some absurd astronomically precise figure.

I'm not a smoker, so I consume most of my THC by steeping 1/4 oz of weed in 26 oz of 151-proof rum. (After a week or so, I strain the rum and consume it about a tablespoon at a time. It suits my needs quite well.) I remember from my days of making homemade wine that there was a fairly easy way to estimate the alcohol content of wine by measuring the specific gravity before and after fermentation. Is there any similar method to get a ballpark idea of how much THC is in my rum?
