Most of us has a lot of scrap parts lying around, most are just taking dust and space. This project takes the junk away and replaces it with a dangerously beautiful light show. Now why dangerous? This project uses a laser from an old DVD player – and yes if your eyes gets exposed to its light it could damage your retina. After building one these make sure to direct it to a wall and no eyes should be in its path.
A Basic stamp is used to control the speed of 2 motors, each motor is driven by an NPN transistor. The first motor is agled at 4 degrees while the second is at 6 degrees – Varying these angles would also vary the size of the projected laser image. Each motor has a mirror and they are spinned in a random fashion – which produces the amazing projected pattern.
I hope you guys find a safer laser source than a DVD and a more controllable light show like the ones where you can load patterns into.
To spice up his daughter’s birthday party PeckLauros fashioned a tricky contraption that seems to come from an old movie house. It’s actually a replica of a camera that sits in one of the corners of their party place – but this one is not an ordinary camera replica – this one actually roles the reel when someone comes into its range of vision. To make it clear it only roles the reel not really recording things – but kids love it.
This neatly constructed piece of work was made using PVC tubes, elbows, a servo moto, a couple of DC motors and of course who would miss out – the microcontroller. PeckLauros used a basic stamp in conjunction with a servo motor and an ultrasonic range finder. The ultrasonic range finder emits ultrasonic waves when an object comes near enough the echoed waves will be detected at the receiver which will trigger the basic stamp to send pulses to the servo motor for the slate and also triggers the DC motors that will turn the reel. Cool huh?
As a human being, we’re only a very tiny part in this universe. Hence, many people, especially the scientists and astronauts are trying their best to explore the unknown space territory and unveil the mystery behind the universe!
Well, people always thought it’s hard to reveal the truth of the universe, as we need to have some very high-end equipment to perform this task! Believe it or not, there’s an easy way for the ordinary civilian like us to experience the fun of space.
Yep, all you have to do is developing your very own “The BalloonSat Extreme” device. To be honest, the goal behind the BalloonSat is to give opportunity to an individual who want to create an experiment for near space.
The greater part about this project is he/she didn’t need to worry about the launching, tracking or recovery processes, but just rather focus on developing a great experiment, which is suitable for the flight into the near space.
For your information, the BASIC Stamp 2pe (BS2pe) is the main part of the BalloonSat Extreme. The BASIC Stamp is used to optimize the battery operated data loggers. The BalloonSat Extreme has the ability to store up to 30 kb of data, which is allowing you to collect unlimited data that keep you busy for the whole week analyzing it!
Robotic is always a very fascinating stuffs, as it can be used to perform different kind of tasks after you’ve well-programmed it. If you’re one of the loyal fans of robotic, then you must check this Nickel-O-Matic robot.
The main goal of this Nickel-O-Matic robot is to print a cool message on a wooden token. It’s as easy as ABC to develop this Nickel-O-Matic robot. It uses inkjet technology to print a custom message on both sides of 1-1/2″ diameter blank wooden nickels. A BASIC Stamp 2 is being used to control the mechanical movement while a Propeller Chip is for controlling the inkjet system. Both of the controllers run a total of four hobby servos, three stepper motors, one DC motor, one DC vacuum pump, one inkjet head and five IR sensors.
In this project, the inkjet system is the most complex part of the modules. A spindle rotates the wooden nickel under the inkjet head right at the center of the inkjet module. Beside that, a Propeller Chip is requiring to control all the elements of the inkjet module. You have to make sure that these two components always situated on a good condition, as they are responsible for direct control over the inkjet head!
After you’ve done with all the modules, you can easily mount all the components into a 20″ square wooden base and enclose with a clear plastic cover. Now, you got your very own Nickel-O-Matic robot!
