Using a Parallax Propeller chip Luis created a way to add some realism to his RC truck. Hazard lights flash and even make the clicking relay sound when activated. The propeller plays the wav files that bring the truck to life. Nice effect when the truck starts moving, you can hear the motor start to pick up speed. There is a product called sound racer that lets you bring your
If you want to scare some kids as they approach your house to get some candy on Halloween have a look at this project by GreatScott. He uses an Arduino which has an ultrasonic sensor connected to it. The sensor detects when someone gets into the scare zone. To scare the curious kid some LEDs light up the pumpkin and a buzzer sound. This idea could be adapted many
So if making a robot that can be remotely controlled wasn’t a tough enough challenge the guys over at Ufactory decided to make one that can roll around on a ball. Great looking design and it sounds like they are going to do a Kickstarter for it and release it as open source hardware to the community. I can’t wait to see a larger version that can be ridden
 RC cars are fun but why let the fun end at driving it around with the supplied remote? Shazin Sadakath got a car and tore it apart to see what made it tick. He took an Arduino and was able to hack it into the car circuit to be able to control all of the car functions with the digital IO Arduino pins. After learning how to interface
We have seen cut away models of things like conventional gasoline engines but this 3D Printed Jet Engine is amazing because it was 3D printed! In fact you can print your own copy since the creator has shared the design on Thingiverse. I guess the next logical step is to print it from metal and run it on jet fuel instead of compressed air!
One common theme amongst 3D printers is that most of them print layer by layer. The printing is normally started on a flat build platform and grows from there. This is limiting though since with this limitation you would not be able to do things such as build a design around a curved platform or on an irregular surface. This 6 Axis prototype 3D printer changed that by giving
If you are looking for a costume for Halloween why not do a Minecraft theme? There are quite easy to make because of the 8 bit theme. A color printer, some cardboard or foamboard and some glue will get you along way to constructing something that will look cool and be recognized by many.Â
