Introduction On request I have built a microcontroller-based doorbell system which is being used in an industrial environment. This is the basic function: When you push the bell-button, a horn will sound for about 10 seconds. At the same time a light, which keeps burning until someone pushes a reset-button, will be activated. The system […]

This Instructable will take you on my journey to replace my old Netflix/Vudu Bluray player with a PC based entertainment station for my LCD projector. I wanted to be able to access and control Netflix, Hulu, Youtube, Crackle, NBC, ABC, and the Weather Channel using only a simple remote control. Along the way, I’ll give

Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. We are widely familiar with the Password based e-locks and might have installed in our house. But we are going for Electronic locks made by any company when you can make one

Aim: – To simulate a circuit using microcontroller 8051 for verifying password. Theory: – The block diagram for microcontroller based password verifying system is shown. The purpose of the circuit is to verify the password entered by the user. An 8-bit password is the input to this system (A simple example has purposely been dealt

The ultrasonic position system uses ultrasonic transmitters/receivers to triangulate position of the robots used in GE423. Each of three transmitters uses a distinct frequencies: 23 kHz, 31 kHz, and 40 kHz. The 2812 DSP is used to measure signal timing and calculate position based on these values. The design of the electronics, as well as

Introduction This circuit is a repeater for GPS data. It is intended to connect to Garmin-38 (and similar) hand held GPS receivers that don’t have external antennas. The purpose for the repeater is to allow the GPS to be outside, exposed to the satellite view, and allow the user to see the data below decks

This page describes a SX28-based color video game system I made during year 2002. Now, beginning of 2007, almost five years after I made the first design I’ve updated the layout of the PCB and added a version of the PCB that has built-in gamepads and I also have made it possible to buy PCBs,
This text describes how to build my PIC16F84 based game system, before you start you should read through the whole text one time. Note that many components are sensitive to too much heat and will get damaged if you heat them too much when soldering. The drawn placement images show components to mount in each

This page describes a PIC16F84-based video game system I made and first published back in the beginning of 1998. Now, beginning of 2007, nine years later I’ve updated the layout of the PCB and also updated the source code to also be able to run on a PIC16F628A as Microchip is phasing out the 16F84
For a while we have been sharing many electronic projects for engineering students and then we found out there was a huge demand for embedded projects, especially PIC microcontroller based projects. After a short break, here is another outstanding one that is not only suitable for electronics engineering but mechanical engineering students too. Now coming
