Requirements:
- something to measure food portions when calorie-counting (should be easy to re-zero the scale so that additional ingredients can be added; would be nice to be able to measure ≥2lbs so that a mixing bowl and several ingredients can be handled; should be as precise as possible)
- something to measure the weight of my loaded bike bag (and other bike parts)... my bag allows me to carry a large amount of cargo, but the weight is really killing me now, I need to optimize that (and at some point, I might get more into serious performance, and weight of ALL parts is a major concern then)
Notes:
- requirement to quickly re-zero/tare basically means it has to be digital, rather than mechanical
- requirement to be precise yet handle large weights also heavily leans towards digital
- prefer to have it in metric (we really need to work on not being the odd man out, people...)
- prefer to have a resolution of 10g or less (0.022 lbs, or 0.35 ounces)
Solutions:
- there are small SOHO digital postal scales that can handle max 2 or 3lbs... for instance, the local Wal-Mart has one for $22, with a resolution of 0.5 ounces
- Becky can get me an old DELI-COUNTER scale (eg. huge and precise... 20+lbs max, 0.01 lb resolution) for $25-50!!! (from American Science&Surplus)
- Becky could also get me a triple beam balance (eg. what you use in chemistry lab) for $50-75 (max 600g / 1.3lbs, resolution < 1 gram) (also from American Science&Surplus)
Okay, this fails at least two requirements, and is more expensive to boot, but the geekiness factor of having chemistry equipment sitting on my kitchen counter just might make up for that
