 1. Remote PC User Interface: I designed this circuit so I can control and monitor multiple of devices from my computer, such as lights, power, motors, and the like. This is called Friendly Computer Graphical User Interface, or GUI. You may download my GUI by clicking on this RemCont.exe. I implemented a very easy to use features into this GUI interface to allow the user to change data values and labels on the fly, a feature that I couldn't find anywhere easily. For this reason I designed it and will make it available to the public at very affordable rate. As you can see from the movie by using the computer mouse and clicking on the desired device you can activate it or deactivate it just like that from the tip of your finger. You can also change the property of the device on the fly. I can extend this user interface to control hundreds of devices so you can have complete control over your house, factory, warehouse, office, department, or any thing you can think of.

2. Smart Embedded Clock Communicator: This device I designed can connect to the telephone line and send messages and reminders through the telephone line between various parties. It is also equipped with personal reminders, clock, alarm clock, hourly announcer, and chimes that reminds you of various events. Easy to use and easy and set up. Email me if you have any question or support. This movie, and many others in this site, are taken by my low cost video camera so the clarity of the LCD screen at close shots is not that great. However you can see how the date on the top, time with AM and PM indicator, clock seconds change every second, and few personal reminder messages are also displayed. File size about 6.7 MB.

3. Hi Voltage Generation: Do not read this if you don't like to see 500 volts sparks coming from my project. Well if you enjoy Hi Voltage then go ahead and play my Hi Voltage movie. This is a very exiting circuit I designed that can be used to generate up to couple of thousands of volts, unfortunately I didn't have the proper electronic parts that could handle that hi of a voltage so I used what was available to me at home. This is about 500 volts coming out of the leads of the charging caps. See my article on how I generated this hi voltage by clicking on here. Please DO NOT try this at home if you are a beginner, you could heart your self. I am not responsible for any damage that results from any mishandling of the electronics described in my web site. Well, I have been jolted many times by 500 volts at work place because I worked with hi voltages so many times. Well most of my time I play with voltages between 0.01 uV non DC up to 24 VDC. I don't recommend you should get jolted though! It is not fun, but it is a lot of fun to watch it. Sit back, relax and watch my sparks…

 4. Wireless System: This design transmits a wireless signals to control any device you can think of. It has a display system that shows the status of the system at any time. The design is very compact and slim that can fit in a very small compartment inside your wall or can be mounted on the table or the ceiling. It also can be programmed to track people activity and trigger special events depending on activities. It has the latest motion sensors and voice technology for smart system operation and user interaction. I can add or remove different features to tailor your special needs, so feel free to contact me with confidence.

5. Remote Fire Works: I must caution that failure to notify authorities in you local area prior to using such devices may constitute a violation of the law. This movie shows a remote control operated fireworks that I believe will dramatically reduce the risk associated to using fireworks and especially the solid fuel propelled rockets used by many hobbyists. Many rockets though are sold with electronic ignition system in the same package. In case you buy a rocket that doesn't have an electronic ignition system then this project may prove useful. This project added to it a lightweight servomechanism below and a remote control, makes a nice graduation project for the electronic enthusiast students. Please play safe.

6. Temperature Control: I designed this circuit to control the temperature of heat exchange chamber in order to maintain a constant temperature predetermined by the user. When the hot or cold air enters the chamber either the heater or the fan starts to bring the final temperature to the desired level. Once the heat exchange is complete and the final desired temperature is accomplished either the fan or the heater is inhibited until the next temperature disturbance cycle. Both the Fahrenheit and Celsius degrees can be dealt with. The temperature is/can be set for minimum, maximum, and hysteresis break points. This will minimize the inductive in-rush currents that may damage any control system components. Any further features or controls can be added to tailor the need of that specific application.

 7. Speech: This project I designed and programmed involves a system that produces speech when certain conditions are met. Multiple voice or music sections are played electronically depending on condition encountered. Can embed almost anywhere, even in your shoe. Click to download Quick Time. Size is 1.6 MB.

8. RFID: This is a complete RFID system that I designed and programmed from ground. It identifies a group of people via their RFID tags, with adjustable distance from 1 inch to 600 meters, and will time stamp their activities. Data can be transferred to any PC for further processing. This system also has many other features that I embedded with such as IR measurement mechanism, motion detector, activity and time monitoring circuit, power management, and more…

9. TV I tortured: I originally obtained this low cost TV to pull its Fly Back transformer for purpose of generating high voltages. It also got some other nice parts. Quick Time MOV. About 2 MB in size.

10. Servo Mechanism: This bird is showing its acrobatic skills on the servo! This mechanism I built and programmed is controlled by a microcontroller that computes the difference (error signal) between an incoming signal (variable resistor pot, joystick, human interface device, and so on…) and feedback signal. Based on the error signal the servo motor angular position is re-adjusted accordingly. This servo may be used to electronically and accurately position mechanisms such as the satellite antenna, air plan deflection plates, robotics manipulation and others.

11. Security: I designed and programmed this circuit originally to function as an Electronic Article Surveillance (EAS) device and be used in the market place or the retail stores. This device connects to Point Of Sales (POS) equipment and authorizes the lawful possession of purchased merchandise without triggering the store alarm system. It uses electromechanical, optical electronics, and decision-making algorithm to electronically secure store merchandise. Quick Time. About 1.9 MB.

12. Robot: This robot I built was intended to help my wife but still long way to finish. For now it drives from point A to point B with the guidance of colored traces on the floor, programmable path, or by the wireless remote control. It moves forward, turns right, left, and moves backward. I bought this cart from used items store and had some mechanical problems with it. I think I need to buy a better one. Quick Time. About 3.4 MB.

13. Radio: Look at that little thing between my fingers, it is a complete radio system in a TO92 3 pins package. I built this MK484 AM radio with very few components around it and LM386 Op Amp. The MK484 powers from 1.2 VDC only, the LM386 from 3 VDC. The sound quality is great and pretty loud. Quick Time, about 5.7 MB.

14. IR Detector: This Infrared system detects property of objects in motion by emitting the invisible light and receiving reflections from passing by objects within the detection zone. In this project I used it to extract the speed of any encoded object such as moving wheel or belt conveyor in the assembly line or supper market store. As you can see the encoded object is being the rotating plate that has black surface on one side and white surface on the other surface. When the surface is white the green LED is ON and when the surface is black the LED is OFF. The MCU can then perform simple data capture and calculates the rotational velocity. It also can be used to detect motion failure (if assembly line is stopped, slowed down, or changed speed) or can detect motion direction when these white and black labels are put in certain arrangement. Play this video and observe how the green LED in the back flickers at a rate following the rotational speed of the black and white plates. Quick Time. About 1.34 MB.

15. Home Automation: This Smart Home Automation System (SHAS) I designed and developed is capable of automating the lightening system of the modern home. It has smart algorithm that saves you money on your electrical bill. It also has programmable smart timers that can be set to automate many different user options. This system is a must for all modern homes. Please email me if interested in such system.
