If you've ever had the chance to play with a vibrating robot toy, you'll understand just how fun they can be. Most of the ones I've seen are of the wind-up variety, typically with long metal lets and rubber feet. They tend to be noisy, bouncy, and definitely unpredictable.
While I've played with various different versions of these wind-up toys for hours, I never really considered that I might be able to actually make one of my own. I certainly didn't think I could make one that is not only just as neat, but a significant upgrade.
Imagine my surprise when I happened across this article explaining how to make a battery-powered vibrating robot toy out of the head of a toothbrush! With the right supplies on hand (including an appropriate toothbrush, pager motor, and watch battery) this project can be completed in about five minutes.
It's really worth watching the video to see just what this little critter can do. I imagine it would enthrall my children, but even more fun would be to watch my uncle's cat go crazy trying to figure out just what this thing is!
It's shopping day, you've got the whole family at the mall. Come lunch time, where do you go? The
There was a time when I had such a huge collection of empty beer bottles, I didn't know what to do with them all. I was too lazy to recycle them and get the deposit, so they just keep kept sitting there, mocking me. And it's not a cool collection, you know? My brother-in-law has all sorts of unique beer bottles from all over the world, many unopened (but most of them empty, of course). He displays them proudly, and I feel jealous. Not an intense, burning jealousy, but more of a mild, passive-aggressive jealousy. But this isn't about him and his cool bottles, it's about me and my regular ones. Well, I guess it's about anyone that has beer bottles, but please stop interrupting and let me finish my story.
As a lifelong avid gamer, I had never really considered the "problem" of staying abreast of my children's video game -playing habits. I simply figured that I would likely be involved in any gaming that they did, so I'd be able to monitor it from the inside, so to speak.
While this is certainly a very easy DIY project, I beg of you, please don't do it. But if you do, please send us a photo so we can all point and laugh.
Everyone knows how to ride a bike, right? But amazingly, not very many people know how to teach someone how to ride a bike. If you're considering taking the training wheels off of a youngster's bike and teaching them how to ride a two-wheeler, your first step should be to make sure they want to learn it. Children run on very different clocks, and some will want to learn at very early ages, and others will be content to wait a year or two.
