New Electronics Series from Becky Stern
My old Make: colleague, Becky Stern, has a new video series that she’s doing for the electronics component company, Digi-Key. Becky has always done an impressive job of explaining what can be intimidating technical information in an entertaining and digestible way. If this first installment, an introduction to LEDs, is any indication, this series looks to deliver more of her welcome brand of accessible tech education.
How to Get Clearer and Stronger Transparent FDM Prints
In this CNC Kitchen video, Stefan shows the special settings you can use to create superior-looking clear prints using an FDM (Fused deposition modeling)printer and clear filament. He also looks at how these parameters make your parts super strong.
Making Your Own Vinyl Stickers
If you’ve been attracted to the idea of creating your own custom vinyl stickers, this video shows you how. All you basically need is a crafting vinyl cutter (a few hundred dollars) and some sheets or rolls of vinyl material.
CA Glue Accelerator from Baking Soda and Water
One of the best takeaways from this Bill Making Stuff video (where he celebrates his 50th episode) is his tip for creating your own accelerator for CA glue. As you likely know, there are commercial accelerators, but they smell funny, have nasty stuff in them, and are combustible. You’re even supposed to wear eye protection when using them, though nobody does. You may also know about using baking soda as an accelerator. It works great, but it leaves a dusty powder on everything that you have to clean off. Bill mixes his baking soda with water in a spray bottle and has found that it works great and creates less mess. I will definitely be trying this.
How a Gas Pump Knows When to Turn Itself Off
If you’ve ever wondered how a gas pump nozzle knows when to shut off when your tank is full, this video reveals the clever design. Venturi tubes, Bernoulli principle, negative pressure — it turns out the design is far more complicated that you might expect. I always assumed it was some sort of an electronic sensor, but it’s purely mechanical.
“I was surprised to see a recommendation for the OXO sink strainer. I love OXO products, but that strainer is a disappointment to me. I do like the inversion feature, but stuff still gets stuck in and around the holes. The silicone gets slimy. I have black slime after a week in my kitchen drain, probably from teensy bits of lettuce and herbs and salad dressing. UGH. (Cleaning out the bowl with a paper towel before washing it seems to help.) I don’t know that a standard issue strainer would make me any happier (though I’d love to quit using so many paper towels). I’m glad yours pleases you; my experience is just different.”
This is a great example of that adage made popular by early hacker culture: “Your mileage may vary” (YMMV). When I posted my review of the strainer on Boing Boing, the first few responses were similar to Candy’s and I got nervous, thinking I had prematurely decided a tool was a winner without giving it an honest testing myself. But then the positive reviews came and they were the overwhelming sentiment. And on Amazon, it has 17.5K reviews at 4.7 stars. After a month, we are more than happy with ours, but, as in all things, YMMV. Thanks for sharing your experience, Candy!

Cool tools really work.
A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
I’ve been wearing a Fitbit since late 2009 and overall I highly recommend it.
The Fitbit is expensive for a pedometer ($99), but in return you get wireless syncing of your steps to your computer and to fitbit.com. Plus you can add friends as “Fitbit buddies” to compare how many steps everyone took each week. I’m currently in a year-long competition with my brother-in-law to see who can take more steps. Inspired by the Fitbit, I will often do 1:1 meetings as a “walk and talk” around the block instead of sitting in a room. I take the stairs at work instead of the elevator. I park my car a couple hundred yards from work instead of close to the building. So far since later 2009, I’ve taken 7,715,383 steps. That’s 3000+ miles towards better health!
What’s not so good? The Fitbit costs a bit much, although I think it’s worth it.
The other (mild) issues I have with the Fitbit are that:
Water can short it out. Don’t go swimming with it on, and attach it somewhere that won’t get 100% drenched in sweat.
Overall, I think wearing a pedometer (Fitbit or otherwise) is one of the easiest/best things you can do for your health. This tool is highly recommended.— Matt Cutts
I use a Fitbit, too. The wireless syncing means that you don’t need to think about it. The hardest part for me is to remember to move the device if I change my pants. The simplicity of the website, and of the user interface on the object, entice you to use it, and to pay attention to the results. It is a small thing that works well and a habit that is very sustainable over the years. — KK
I’ve been using my Withings WiFi-enabled scale since 5 Dec 2009, at which point I weighed 246.9 lbs. Today, I weigh 183.5 lbs, and this scale helped me reach my goal. It shows weight, percentage or lbs of body fat, and BMI. Because it’s WiFi-enabled, the readings are picked up and displayed graphically on my Web page (password protected) at their site with the option to share it with other web-based weight loss sites. Moreover, I can use the data locally by downloading the readings in a format suitable for a spreadsheet.
I weigh daily, and the graph has greatly helped in my weight-loss efforts. Now I can easily see the trend, which helps manage it. I’ve had a series of scales that measure both weight and percentage body fat, including a couple by Tanita. As part of my weight loss effort, I did have some professionally administered body-fat measurements, and the Withings readings were consistent with that, within the limits of accuracy with respect to one’s daily weight fluctuations. If you have multiple people using the scale, it’s easy to set up multiple accounts (it has a maximum of 8 users). —Michael Ham
High-capacity measurer
Digital Freight Scale I’m a big dude so most scales don’t even cover my weight. Consequently I had to think different to get a decent scale. I found this digital postage scale. It reads up to 400lbs in half pound increments, has a remote, mountable readout auto tare (useful when weighing the dog). It isn’t particularly pretty but being in the top percentile in weight and height has certain drawbacks and requires special tools. — Bryan Covington
A physicians’ balance beam scale is consistently accurate. We’ve had one now for at least 25 years; its accuracy has remained constant through many moves, changes in humidity, and so forth. Measurement is in 1/4 pounds, which is good enough. There is a readjustment knob if you think there is an error when changing the scale’s placement. If only my weight and height had remained so constant….— Martha Robinson
If you want consistency and accuracy in a body scale, I strongly suggest an old-fashioned balance beam scale. Even a cheap one (<$200) will do a better job than most expensive electronic scales. Also, they are kind of fun to use, they have an eye level display, and the batteries never run out. — Danny Hillis
I’ve been using the BodyMedia FIT armband for the past 3 months and it is the only diet and exercise system that I’ve found that really works. The system works through the use of an armband that you wear on your left arm throughout the day. As you go about your regular routine the armband measures your caloric burn. The armband uses four sensors to track over 9,000 variables from heat to sweat to steps to calories burned every minute of every day.
You can track your daily burn and steps taken through an optional display, but the real power is in syncing the armband to the BodyMedia web site which allows you to see charts of calories burned per minute, steps taken, exercise levels, sleep cycles, etc. You can also track your weight measurements in the tool. The great thing about the online tools is that it lets you enter your daily caloric intake (just search for a food and add it to a meal), and compares your incoming calories to outgoing calories. By entering your calories on a daily basis you can ensure a realistic caloric deficit which is guaranteed to help you lose weight safely. It’s very helpful for making sure you don’t starve yourself by eating too little, or conversely, that you don’t go crazy and eat too much.
Since I started using the armband I’ve dropped 20 pounds that I’ve managed to keep off with almost no trouble. It’s become pretty simple for me. I can eat a healthy but normal breakfast and lunch, then I check my calorie burn before dinner and make sure to eat the appropriate amount to ensure I maintain my target calorie deficit.
What I love about this tool is that it eliminates estimation. Everyone has different basal metabolic rates depending on what they do during the day. Whereas most diet systems target a fixed number of daily calories, those fixed amounts could mean anywhere from a 500-2500 calorie deficit depending on the person. Anyone who’s dieted knows that when you get into high calorie deficits you’re body stops losing and you go into the so called starvation mode where your body actually holds onto the weight. With this that never happens. If I have a lazy day at work and am on target to burn 3200 calories then I know I can eat 2200 and maintain my 1000 calorie deficit. But say, I go for a long run on the weekend and do some yard work I could get up to 5500 calories burned. If I stuck with a 2200 calorie diet, my body (and my willpower) would rebel. However with BodyMedia, I know that on those 5500 calorie days I can eat 2000 more calories and still be on target for weight loss.
Long story short – I absolutely love this system. — Marc Ryan
