Have you ever heard of a walking machine made from bent wires and run by a single 1.5V AA battery wherein the motor and battery can rotate with crank? Hackolog member brought this amazing concept, where you can build your own walking machine just by using fewer components. You can start by connecting the motor to the crank to which the wheels are fitted. Now when the wheels meet an obstruction the motor starts
If you want to drive the guys over at Open Picus nuts send a tweet to their dancing santa! Check out their Open Picus Dancing Twitter Santa project to see how they connected the santa with a few bits of electronics to their system. I have a feeling that this will be a fun gadget on the desk until it keeps dancing non stop for a few hours… “I
Makezine in its blog reported that Yoonjo Choi has modernized her old typewriter by adding force sensors and monitor connectivity, so that her old photographs can now be flipped quickly through projection. The way in which her old photo displays on the monitor possesses a magical effect. The project draws attention to the photos in a way that a digital slideshow or picture frame cannot. The most amazing feature is that you can only see the photo
Our friend Viktor sent in his latest build. He took a $1.99 IKEA plastic bag dispenser which looks great for only a few dollars and used it as the structure of his DIY moodlight. I visited my first IKEA last year and was quite amazed at how they create an experience that I have never had in any other store. I had to hold back from purchasing a ton
Thanks to Ben from NBitWonder for sharing his Software-Defined Radio project with us. “There is much more work to be done on the software, as you can tell from watching the video. Â For instance, only AM reception is implemented right now. Â The signal processing functions still need some work, and more appropriate gains should be chosen for the entire signal chain. Â Still, it is rewarding and reassuring to see the
We have seen single color LED detection before, fjordcarver has built a DIY Color Detection using an RGB LED that can detect the actual color of the object placed in front of the home made sensor. “For this sensor you will need a breadboard (not required, but it is how I will walk you through it.) an RGB LED (alternatively you could use 3 LEDs) A 220 ohm resistor A
Ben goes over some basics of CPLD and FPGAs. If you need a ton of power and a microcontroller just won’t cut it, it might be time to move up to a CPLD or an FPGA. Watch as Ben shows us some results of the first few Hello World like programs he runs on an Altera CPLD. Looks like there would be a steep learning curve to become proficient in
