Officially (or unofficially), RC helicopters are DEAD as we know it but quadrocopters are become ever more popular. For those of you who’s thinking about building yourself one, you might want to take a look at this particular setup using Arduino and Wii Motion Plus.
The project uses Wii Motion Plus coupled with I2C communication to Arduino unit to make use of the gyroscopes inside and also save a bunch of money on the setup.
Here’s the coolest robot of the week you can build, a tree climbing Arduino robot! I love this idea and would like to take the concept further by adding some wireless cameras so I can snoop on the baby birds hatching. See Instructables for full instructions on how to make one yourself.
Want to make yourself a DIY animatronic mouth robot? Check out PyroElectro.com’s instructions on how to build one of these using PIC controller and servos.
In this tutorial I will show you two simple methods for building a believable robotic mouth. One articulated and moveable, the other an LCD flashing design. Both animatronic mouth designs create a believable illusion for your animatronic robot and can be built on a modest DIY budget.
Want to make your 3 or 4 year old get good at numbers super quick? How about building your kids a DIY counting box?
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.
One of the coolest devices for cooking and brewing is a temperature-controlled crock pot. I actually have a similar project that I am working on using a PID to control the temperature of my Korean rice wine that I brew at home but you can use this example of a DIY PID-controlled crock pot for many applications.
There are some home appliances you simply can’t buy (way too expensive) but you can make them yourself using a PID controller.
What is a PID controller?
PID controller is basically a piece of computer that can control temperature of another electr
Adding a touch-input to your next project can enhance its user experience but did you know that a simple touchpad isn’t rocket science but do-able under budget?
Giorgos Lazaridis shows you (and even shares his circuit diagrams) on how to make such DIY touchpad input device, and believe me, no one wants to push physical buttons these days.
I made this circuit, because i faced several problems with the touch-pad for my keycode doorlock project. I tried many different touch-pad
POV or Persistence of Vision where you use flashing LED lights to display letters in motion, has always been a fun way to learn about LEDs and circuits. You might remember I invented the world’s first Golf club POV, which was capable of showing letters/images while you swing the golf club.
Well, there’s a DIY Doggy Style (literally doggy dog) POV someone has managed to put together with his furry little helper helping him in pitch darkness.
Mounting 5 LEDs on a moving o
DSLR videography has literally exploded in the last couple years and I am a huge fan (you can read up on my DSLR videography recommendations here); here’s a great hack that can let you trigger video on your Canon DSLR by hacking the IR controller with Arduino so you can turn the video on/off from up to 150-300 feet range.
I had a problem that I needed to solve:
Remotely and wireless-ly trigge
Need to add eye-movement detector for your next project? Check out what Luis Cruz (a senior in high school) did, a low-cost DIY eye-movement detector. This is amazing, not only that he was able to do it for low cost but this kid is simply GENIUS!
The human eye is polarized, with the front of the eye being positive and the back of the eye being negative. This is caused by a concentration of negatively charged nerves in the retina on the back of the eye. As the eye moves the negative pole moves relative to the face and this change
Here’s a really funky project Jeremy Cook invented from scrap parts incluing his old RC car. The result? Really creepy box that sorta comes alive. Muhahahahaha.
This reminds me of the World’s Most Useless Machine, only a bit more creepier.
