The PortaPAL Public Address System-Part 1 -  It's packed with features, is easy to build and rivals commercial systems costing much more__ SiliconChip

The smallest handheld automatic one-chip AVR-based DC voltmeter -  Have you ever tried to repair anything in your car? Have you tried to debug your original circuit? If yes, then you are sure to have a device called multimeter.  Usually this thing is about half a kilo heavy and you would normally have to hold it

The SMS remote controller -  It's been passed a lot of years since my first SMS remote control.  The reason I stoped developing the source code of my previous circuit was that the T10s was not available in the market sinse a lot of years.  So,  __ Designed by Vassilis Serasidis

The SportSync Audio Delay Module -  Many sports fans feel that radio commentary is better than that on TV, particularly commercial TV.  To eliminate the annoyance of the TV commentary  (and the adverts) they want to turn down the sound on the TV and listen to the radio instead.  But the delay in the live TV broadcast causes a major problem.  This simple project lets you delay the commentary on the radio to match the action on your TV - and it's remote controlled.__ SiliconChip

The TuxGraphics AVR NTP Clock -  Abstract: The Network Time Protocol  (NTP) has revolutionized the world.  Suddenly one could have anywhere in the world accurate time and date.  NTP is a simple UDP based protocol and can be implemented in a Microcontroller.  Using the tuxgraphics __ Designed by Radio LocMan

The USB MIDI-Mate: a MIDI Interface for PCs -  An up-to-date MIDI interface for PCs__ SiliconChip

The WB0RIO 28 Mhz FSCW Beacon using an Arduino -  This circuit uses a 6U8A triode/pentode tube as the heart of a code practice oscillator  (CPO) .  It is simple enough to be built by a beginner and would be a good introductory project for those who want to experiment with vacuum tubes.   The circuit produces a hi-fi sinusoidal output with a wave-shaped envelope for minimal key clicks.  These features reduce operator fatigue and make the CPO easy to listen to for extended periods.  For contrast, see my solid-state Smooth Tone Clickless CW Sidetone Generator project. __ Designed by G. Forrest Cook

The Witness camera. Part 1 -  Part 2 Part 3 Video surveillance systems have rapidly grown from being a specialized equipment for high-risk areas  (like banks and airports) , to the point of being standard facilities of most places open to the public.  Nowadays, no shopping centre, 

The Witness camera. Part 2 -  The most peculiar aspect of this design is that the firmware is written in BASIC.  I’m a strong advocate of using C for embedded systems, and I use routinely the excellent GCC compiler for AVR development on PC and Linux platforms.  But at the

The Witness camera. Part 3 -  Part 1 Part 2 I started the development with the card and the camera connected to and Atmel STK300 board and a Mega128 chip.  Developing on a larger chip facilitates development, as you have extra pins, flash and RAM to use for debug.  Once I gained

The World's Simplest Open Source DIY MP3 player Sakura -  For around $30 in parts and a good amount of patience, you can have a completely open source and hackable mp3 player ready to go.  It can be modified to accept serial commands, be embedded in an art project, used as the voice of your next smart __ Designed by Radio LocMan

Thermistor Thermometer -  Simple thermometer made with NTC thermistor.   __ Designed by Wichit Sirichote

Thermometer-Thermostat -  This is a simple thermostat that i designed to use with my central heating system.  When is not in use acts like a thermometer.  The prototype uses the AT90S2313 but it’s obsolete now, so i changed it with the pin to pin compatible ATtiny2313  (the photo shows my first prototype) .  __ AVR Projects Dim

Thermostat Uses Capacitive-Sensing Liquid-Metal Thermometer -  Capacitive sensing is a versatile technique that can solve a difficult sensing problem in a surprisingly simple manner.  For example, it can be used to turn a liquid-metal thermometer into the sensing element of a thermostat.  Such __ Designed by Elio Mazzocca

Three Do-It-Yourself PIC Programmer Kits -  These low-cost kits are easy to build, come with sample programs and are just the shot for getting started.__ SiliconChip

Time Switch V1.0 -  New weekly scheduler made by 68HC908QY4 with kaypad and 16x1 line LCD!  (not recommended)  __ Designed by Wichit Sirichote

Time-Controlled Switch using PIC16f72 -  APRIL 2012: A time-controlled switch is an automatic timer switch that turns an appliance ‘on’ for the desired time duration.  After the preset time duration, the timer automatically switches off, disconnecting...__ Electronics Projects for You

Tiny 2313 Project Development Board -  This is my first time using the AVR.  I like to learn using the ATTiny 2313, because it is faster than MCS-51, cheap and the circuit is very simple.  The chip has only 20 pins.  I was interested because I want to build a simple line follower robot controlled by this MCU.   __ Designed by Tahan Prahara

Tiny Eprom Simulator -  Program development for stand-alone micro processor systems can be done in many different ways.  This project is intended for processors with external program memory.  Modern processors with internal Flash memory will not benefit from this project and must be programmed in a totally different way.

Tiny Header Boards -  These are two tiny boards that make your prototyping on a breadboard much easier.  Just plug the header board into the breadboard and attach your ISP programmer and you are ready to go.   __ Designed by Alexander Weber

Tiny Microcontroller Hosts Dual DC/DC-Boost Converters -  05/15/08  EDN-Design Ideas - An Atmel AVR microcontroller can serve as the PWM controller for two DC/DC converters that provide high voltages from a two-cell supply __ Circuit Design by Dhananjay V Gadre, Netaji Subhas Institute of Technology, New Delhi, India

Tiny2313 Proto Board -  This Tiny2313 Proto Board is for all these one-off projects and prototypes.  You want it more permanent than on a breadboard but don’t want make a custom PCB for it.  The board comes with 10 components only and is really easy to solder.   __ Designed by Alexander Weber

Tiny25 Proto Board -  This Tiny25 Proto Board is for all these one-off projects and prototypes.  You want it more permanent than on a breadboard but don’t want make a custom PCB for it.  The board comes with 10 components only and is really easy to solder.   __ Designed by Alexander Weber

Translate a laW to m law -  05/07/98 EDN-Design Ideas -  (NOTE : contains several ideas, scroll down)  Two common methods exist to compand voice for transmission through a PCM channel.  In Europe, A law involves converting a 12-bit input signal to an 8-bit encoded output.  In the US, m law involves encoding 13 bits to 8 bits.  You can use a translator to convert from A law to m law  (Figure 1) .  The converter is asynchronous and requires only an 8-bit A law input to provide an 8-bit m law output. __ Circuit Design by Rolando Herrero, Instituto Tecnológico de Buenos Aires, Argentina

Triangular wave oscillator -  In this page, I introduce the triangular wave oscillator which used the Operational Amplifiers  (TL082) .  The circuit uses the two OP amplifiers.  The OP of the one works as "the Schmitt circuit".  The other OP works as "the integration circuit".  At the circuit diagram above, IC (1/2) is the Schmitt circuit and IC (2/2) is the integration circuit __ Designed by Seiichi Inoue
