Nathan made this "Counting Box" for his son -- I love LED displays set into hand-crafted wood boxes, and the simplicity of this toy makes it a nice blend of traditional toymaking craftsmanship and high-tech electronics:
My son—now four, but three when I conceived this project—loves numbers and counting. More than a few times I’ve peeked in at night to find him asleep with a calculator in one hand and a flashlight in the other. And one of his favorite things to do with the calculator is incrementing “1 + = = = = = = = = = =” until he can’t keep his eyes open any more. I decided to build him a dedicated machine that would do nothing but count up and count down.
My initial concept was simple: a seven segment LED display so it could be read in the dark, a rotary switch in the middle to choose the value to operate with, and big buttons for adding and subtracting. Green makes the number get larger and red makes the number get smaller.
Justine Haupt made this handsome and completely functional rotary cellphone. Her design is open-source and you can even buy a case kit from her company, Sky’s Edge Robotics. You have to find and carefully modify your own rotary dial, though — they’re apparently no longer made — as well as a few other components. Why […]
Samsung claims to have developed an “Ultra Thin Glass” for its new Galaxy Z Flip foldable smartphone, signalling scratch resistance and durability beyond that of similar products. But tests conducted by Zack Nelson using a Mohs Hardness Testkit [Amazon] — a set of styluses made of different materials — show that it is no more […]
There is very little evidence that Ring reduces crime. Hundreds of police departments have signed agreements with Amazon-owned Ring to obtain access to the home surveillance camera footage. Interviews with many of them, in 8 different states, show little to no evidence that Ring actually deters criminal activity.
With so many advancements in modern society, you’d think we’d have moved beyond the butane lighter by now. A pressurized, flammable gas, butane fumes can irritate your eyes and skin, can elevate your heart rate, and even lead to cardiac arrest. And we did mention that whole highly pressurized and flammable part, right? While certainly […]
Is it just us, or does it feel like winter hasn’t been as horrendous as usual this year? Well, stats show it’s actually been one of the warmer winters on record so far this year for many eastern U.S. cities in January and February. But, almost on cue, weather experts warn signs of a serious […]
While mobile devices are all but essential and the center of so many individual universes these days, find one person who loves their wireless plan with that type of passion. Check around. We’ll wait… Didn’t find anybody, did you? That’s because most wireless plans are designed for the convenience of the provider and will nickel-and-dime […]
