weight gain? Answered

This is just one of those strange things that flashed through my mind when I read the other question on Deuterium. Since its just water, and I don't remember ever reading that it is harmful to drink it, I was made to wonder: If a person were to drink enough deuterium over a period of time to replace all the regular water in their body with heavy water, just how much weight would they gain?

Sensor to measure weight.

Hi everyone, I am stuck. I am trying to find a method or sensor to do what I want. Basically, I am trying to make a cheap flat weigh scale- light weight , flexible and portable (carried in a brief case or lap top case); thinner than using load cell sensors. I was hoping for a flat compression fabric , foam or piezo resistive pressure sensor, but have not found what I was looking for. It needs to be able to measure 50 to 250 lbs & fit on a counter. Does something like this even exist? Any suggestions would be most welcome. Thank you Appl314

leg and arm weights

Will someone write up the plans for a HEAVY-DUTY ankle and wrist weight. I have been searching online for a company that will make custom weighted wrist and ankle weights but there aren't any. I'm wanting to make a 50 lb for the arms and 100 lb for the legs. I'm thinking along the lines of several iron or lead bars strapped together with a nylon fiber or other strong material. I've only ever done projects in high-school, where materials were provided, so I don't really know where to get the materials needed. Please help.

Weight Watchers Points Tracker

I'm not really sure how useful this is going to be to people, but as it's helped out several friends, I figured I'd share it here. <<>> A good portion of my immediate family and their significant others have been doing Weight Watchers.  My mom and girlfriend kept asking me when I was going to do it to.  Hoping I might get out of it, I told my girlfriend I'd do it to so long as she kept track of all my points.  She agreed, and so I was stuck. (To be fair, I agreed to Weight Watchers as opposed to any other diet as it seems more of a “how to eat properly/lifestyle” kind of thing as opposed to a “diet” kind of thing, so it also peeked my curiosity.  Like, “How much SHOULD I be eating compared to what I have been?” (Answer: A lot less)  To express this point, you don't have to lose weight while on the program, you can adjust how much you eat to gain, lose or maintain whatever weight you want.  It's kind of interesting to realize the amount of food intake it requires to affect your body.) After a month of letting my girlfriend track my points, I decided to do it myself.  I wasn't going to learn anything about what I was eating if I didn't take part.  Soon after I started tracking, I realized I needed some kind of automated system that I didn't have to constantly add, subtract and keep count of for days at a time.  All of the information was already stored in a fairly easy to follow spreadsheet my girlfriend made, so I decided to add a few formulas to keep track of things a little easier. To put simply, this spreadsheet keeps tabs on what you're eating, how many points it costs, and determines how many points you've used/have left for the day and week.  Like I said, I'm not sure how useful this is to anyone else, but I figured there'd be one or two people out there that might enjoy. <<>> Please let me know if you have any questions...I edited the files a little bit in hopes that it makes more sense.  Feedback is always appreciated. Who this is for: If you want to try weight watchers, or currently use weight watcher, but don't want to pay them, this might help you. If you want to count your calories in a point system, this might be for you. (This is essentially a glorified calorie counter.) If you want to keep track of what you eat, this might also be for you, though it may not be in depth enough. What this isn't: This doesn't tell you how many points things are worth, that's your job. A quick guide to points: Every 50 Calories = +1 Point Every 10 Grams of Fat = +1 Point Every 5 Grams of Fiber = -1 Point (you can't go below 0) (and don't forget to keep an eye on serving sizes!) This doesn't tell you how many points you should shoot for.  Again, your job to find out If you want to lose weight, there's guides online to figure out what it should be. If you want to gain weight or stay the same, figure what you need to do to lose weight, add five or ten points to that and see what happens. This doesn't track Workout points. I don't believe in them, I don't use them, I didn't add them. What this is: You enter in what you eat. You enter in how many points it costs. It will tally everything for you. Tracks Weekly Points which are bonus points that tally though the week These are a buffer in addition to your daily points They count down throughout the week (you don't want them to go to zero) ...use it for a couple of days and it should start making sense. What you need to do to make the most use of this: Download the appropriate file and put it in a place that's easy to access. I use different computers depending on where I am, so I also downloaded Dropbox and put this in a folder that's shared with all of my computers. Figure out how many points you should eat and enter that in the ??????? field on the spreadsheet (see the attached picture). Enter in what you eat, as you eat it, and see how things go. If you use this, and your weight changes, ten pounds more or less, make sure you re-figure out how many points you're allowed to eat. Voila! Now you don't have to pay $17.00 a month to a website to track your points for you! Attached you'll find the Open Office and Excel versions of the same file.  Choose what suits you.

Medium weight quilting Fabric

Hello Everyone, I'm new to this type of project but I was looking to make a knife roll for a friend who will be starting culinary school soon. The one she bought for school is kind of dumpy and while it does the job we had found some great looking roll up ones online they were just kind of expensive. So i figured I could make her one for half the cost. It all seems doable. The wall I'm running into is the majority of my sewing experience has been stitching hems for Halloween costumes so my familiarity with fabric types is minimal at best. I wanted to make her a roll out of a fabric with a print on it and and finally finding the right one, at a good price point, I find myself worried the quality of the fabric may not be what I'm looking for. Basically what I found was described as "medium-weight quilting fabric 100% cotton" another one was called "broadcloth." I, however, have no idea what they are. The majority of no leather knife rolls we did find were made of canvas so I was hoping to make one of similar durability. To sum it all up I'm just wondering if this "medium-weight quilting fabric" is anything like twill, canvas, linen or musslin. I feel like those fabrics, especially the first two, would be quite durable for some like a chefs knife problem is the pattern I'm looking for isn't on those types of fabrics. Any and all help is greatly appreciated. Thank you in advance!

acceptable angle of deflection for temporary support

Hi, I am in no way an engineer.  I'm trying to figure out what is an acceptable angle of deflection for a combination frame and hammock support.  I'm thinking of using the the 80/20 t-slot beams.  I want something that is portable, easily assembled/disassembled for moving, and lightweight.  I'm go to make a box in our garden to protect our plants and when the corn is big enough, move the box around to make a hammock support(chicken wire around the bottom part to keep the critters out).  It's basically a box 6 feet wide, 8 feet long and about 6 1/2 feet high. 4 beams to make a rectangle on the bottom, 4 uprights(1 in each corner), and another 4 beams on the top to make it more rigid.  Chicken wire will keep the pests out but let me in to relax until the corn is too high and I move the frame.  :)  I'll put the hammock diagonally from pole to pole; total weight with me and the hammock is about 250 pounds.  It will be anchored to the 2 uprights with 300lb chain at each end. Using the angle of deflection calculator from 8020.net, I found some beams that had 5mm deflection with 150lbs of dead weight in the center of the 6 foot span.  I thought that even if I anchored the hammock to the center of the 6 foot span, that would be 300 pounds, more than the 250 max the hammock and I will be.  And anchored in the center of the beam is the worst case scenario since I'll be anchored to the corners. But is that an acceptable amount of give in the beam?  It's not meant to be permanent.  I won't be in it more than 2 or 3 hours tops. Thanks!

How to make a weight sensor that turns off a pump at a very precise weight?

Hi everybody! I'm building a coffee maker, well trying to at least, and one of my goals is to have it be that that placing your cup on a sensor pad will read the weight of the cup and then activate a pump to pour in the appropriate amount of coffee to top it off. My thought was that the user would set up a profile when they set up the coffee maker so it knows how much their cup weighs, and this would be stored on a small inboard computer like the raspberry-pi, then placing the cup on the weight sensor would measure the weight of the cup and run a simple equation to determine how much coffee is needed and how long to run the pump to dispense that amount. Unfortunately i'm really new to all of this and at a loss for where to start with programming the raspberry-pi and how to connect it to a pump or a weight sensor, any advise or tips on where I can learn some of these skills would be appreciated! Thanks!
