DIY a Spooky Hack-O-Latern with Song LED Flashing!

Do you having any special plan for the upcoming Halloween festival? Well, you might be thinking, “Nah, is still too early for it…” However, this is the best chance for you to practice your PIC controller knowledge, by DIY a “Hack-O-Lantern”. Before you starting the project, those components you need to prepare here are: Super Bright LEDs, which means you can keeps the Dim LEDs away from this project A Parallax Basic Stamp 2 Microcontroller Board Some nails, which it can be used to hold the micro-controller board onto the side of the pumpkin Computer speaker that will act as an amplifier Sharp knives, and of course A big and round Pumpkin! Ok, firstly, you have to carve your pumpkin and it’s totally depends on your creativity; whether you want to make the pumpkin a scary face, or even smiley face is up to you! You have to make sure that the LEDs will shine through the pumpkin as well. After that, you must hook up your microcontroller with the LEDs and speakers in the same place. Next, you haveā€¦ Continue reading

Eigenbau – The Intelligent Robot Spider

Do you wish to have a “Giant electronic Spider” crawling and bringing some fun to your home? If you’re answered yes, then let’s meet this incredible “Eigenbau” Robot Spider. You need to have these following materials for making this “Eigenbau” Spider: Javelin Stamp microcontroller with Ubicom Sx48AC One ultrasonic sensor with Deva-tech SRF04 Two sensors with micro-switches A Micro servo to the pan of ultrasonic sensor Three Standard Model servos for the musculoskeletal purpose This Eigenbau is well-programmed with Javelin Stamp microcontroller, which the three main tasks: Review or control of the ultrasonic sensor and the sensor Calculate the action, whether is to be forward, flight or Dodge, which based on the sensor data Control of the three servos for the musculoskeletal, where it’s mainly according to the require action to be performed Continue reading

Explore Low Earth Orbit with Satellite tracker

This project can be useful if you are trying to point you antenna to Low Earth Orbit (LEO) satellite. Why do it manually if you can leave this job to automatic tracker based on microcontroller. The brain of this tracker is a Paralax basic STAMP II, which decodes satellite coordinates (azimuth and elevation) sent by tracking program. It also controls DC motor based rotators that positions antenna. 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

GSM alarm project with BasicX Stamp

Pedro Miguel have been developing pretty simple GSM alarm unit controlled by BasicX24 stamp module.   He connected Siemens C35 cell phone to to BX24 board and communicated by using AT commands via serial interface. In his test board used a PIR sensors for motion detection. When motion is detected system sends SMS to specified cell phone. Control code is written in basic. Author left project open for future development and expanding. Continue reading
