Basic Stamp based DIY Laser Light show makes use of scrap parts

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.     Continue reading

Automatic slate camera using a basic stamp

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? Continue reading

It’s Time to Test Your Knowledge about I2C/SPI LCD Interface!

Have you ever tried to deal with the I2C/SPI LCD interface before? If you haven’t, then you might want to test this out by your own! It’s a lucky day to you, as today you’re going to develop an I2C LD interface, which it’s allow you to connect an LCD to a microcontroller with only two simple wires! You will think it’s a useful tool, if you like more pins to be available for another use, which a normal LCD interface requires a minimum of six pins or you would like to make a control panel! Basically, with this I2C/SPI LCD interface you can only use two wires from your microcontroller and use up to seven I2C LCD interfaces on the same I2C bus. Furthermore, you also can be easily wire a five button input pad, example like a control panel and free up your serial port for other use with this I2C/SPI LCD Interface. The great thing about the I2C/SPI LCD interface is it can be used with the Basic Stamp, any Arduino, Microchip PIC or any other microcontroller,… Continue reading

The Greatest Things You Must Know About Arduino Nano!

For most of the home hobbyists, one of the most common breadboards to you must be the Arduino type breadboard! The reason why the Arduino breadboards are so popular because of its high quality and cheaper cost than other boards. You can find Arduino Breadboard available in many types and the Arduino Nano is the smallest, complete and breadboard friendly of all. Arduino Nano is a fine surface mount breadboard embedded version with neat integrated USB on it. The Arduino Nano was been well designed and is being produced by Gravitech. Arduino Nano has everything what Diecimila has. Plus, it has more analog input pins and onboard +5V AREF jumper. Maybe you will find out that power jack and power select jumper was missing in Nano. Well, since the Nano can be automatically sensed and switch to the higher potential source of power, thus it’s no need to include the power select jumper on it! Another interesting feature about the Nano is it got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint, thus you will have more… Continue reading

The Easy to Navigate Free Servo Control Software

Are you fascinated about the Servo and you’re always involving yourself in these types of projects? However, you’re thinking that it’s totally a painful experience, when you can’t found the suitable servo control software, which it’s written in “Visual Basic 5 Pro”? Well, if you’ve been searching for the reliable free serial servo control software for such a long time, then you now can stop the tiresome scouring journey, as you’ve now found the free servo control software, which it’s well written in Visual Basic 5 Pro! Basically, this free servo control software uses the PC serial port “com1” to talk to a Basic Stamp, or a PIC Micro programmed with MicroEngineerings PicBasic. Thus, you can use it to test any hobby servos! The port 0 on the stamp (port RB0) on the PIC is connected through a 22K resistor directly to the PC’s serial port “TX” on “com1”. Furthermore, the stamp or PIC will receive serial information from the pc to position seven hobby servo motors that attached to port pins 1-7. So, what are you waiting for? It’s… Continue reading

How to drive bipolar stepper motor with basic stamp

Bipolar stepper motors are common in printers. They are different from unipolar steppers. Bipolar steppers usually have four wires (while unipolar 5). Bipolar stepper motors can be driven by using H-bridge circuit like SN754410 from Texas Instruments. One SN754410 IC can drive single bipolar stepper motor. In this example you may see two of them, so each motor is controlled via separate H-bridge IC. Whole circuit is built around Basic Stamp BX-24 which can be programmed by using Basic language. Sample source code is available for testing. Continue reading
