    I’ve had a fitbit for about 6 weeks and love it. I fall into the category of people though who want accountability, but don’t care too much about accuracy. Do I care if it says 6500 steps and the real count 6250, no. Do I care it can’t fully accurately track my calories, not really, because, I think, the error will be to under count, rather than over count. That’s because it is just using a simplistic “active”, meaning you are doing something for a while, but you are right, intensity is not measured, ans so is not accounted for. So as a non gym rat casual activity person it works well for me, at the end of the day I want to know how close to the 10,000 steps was I today. I used, and was happy with, the Omron pedometer for years, but I was tired of breaking them, and leaving at home or work. Wearing one 24/7 is also a real advantage.

    If you do the one hand trick, the one that goes in your pocket is your LEFT hand. The reason is that the path to ground from your right hand is down the right side of your body and through your feet. In other words, your heart is not in the path to ground. I don’t know if that would make a difference, but it’s what I was taught.

    I learnt the back of your hand trick in relation to watching something about how to escape from a building in a fire or other emergency, and is a useful one to pass on. If you’re, say, using your hand to find your way against a wall in a dark and smoke filled build, use the back of your hand so as not to accidentally grab onto any exposed wiring.

    Not sure if you do this, but equally important is the regular testing and validation of your test equipment. We make low risk medical products, all test jigs etc are serialized, and a log made of their testing regime. At least, a test fixture must be tested yearly, unless it is classified as “obvious to user when not working”, such as a mouse or keyboard. This regular testing, as well as your production batch logs, would then provide traceability, if you discovered during regular testing of a jig, that it was out of tolerance, or had a fault that meant that a faulty board could pass. The length of time between validation or a test fixture, must be less than expected failures, or for parts to go out of tolerance. All fixtures get a tag indication when they were last tested, and date of next testing, and any user should check them before use.

    Always add a fuse ! You can get inline fuse holders from auto parts shops. They normally come with about 6" of wire on either side of a molded fuse holder with cap for water proof. I normally crimp a lug on one side to connect to the battery, and then connect the load on the other side. Next to the battery, it makes it easy to see to remind you that that is where you put the fuse, but also that you actually added on in the first place.

No public wish lists :(
