A Superhet/Direct Conversion AM receiver for 181.818 kHz using Attiny2313

Downloads Download the AVRStudio assembly source vlflo13041105A.asm (html format) Download the AVRStudio Hex file vlflo13041105A.hex (html format) Photo of completed receiver. Its pocket sized, but not intended to be used that way because the antenna is a highly directional ferrite loopstick. Its only a matter of luck that there was room for all the components

RS-232 to 100 MHz RF desktop channel adapter using ATtiny2313 microcontroller

Leave a Comment / Interfacing(USB - RS232 - I2c -ISP) Projects / Ibrar Ayyub

Downloads AVR Studio assembler source code 2jun2002version.asm AVR Studio hex file 232lin.hex This is an adapter that allows a terminal to communicate via a 100 MHz data channel with peripherals on the same desk top. Keystrokes from the terminal are are received through the RS-232 connection and sent through the 100 MHz RF data channel.

A Simple FM Stereo Transmitter using ATTINY12 microcontroller

Leave a Comment / Radio Projects / Ibrar Ayyub

The parts to the right of the green capacitor are the FM radio transmitter. The parts between the 8 pin DIP and the transmitter are the resistor matrix. One capacitor, C5, is mounted on the back of the board, and one other capacitor, C11, had not yet been installed. It was later installed just below

Multifunction 330 MHz Remote Control With an ATTINY2313 Simulating the PT2264 Encoder

Leave a Comment / AVR ATmega Projects, Radio Projects / Ibrar Ayyub

This 330 MHz remote control sends timed sequences of control pulses to accomplish complicated tasks. You can probably tell that I used a lot of solder flux on this board. Lots of flux not only helps the solder wet to the copper, but it also greatly reduces solder bridges. You can probably tell that I

Simplest LED Flasher Circuit

Leave a Comment / AVR ATmega Projects, LED Projects / Ibrar Ayyub

As simple as it gets and still works This LED flasher occurred to me while reading about negative resistance in transistors. It was reported that Leona Esaki, who was at Sony at the time, had been surprised to see a negative resistance region while investigating production defects in transistors which lead to his thesis work

A 1.5 Volt, 1970’s Style LED Flashing Red Caboose Marker Light using tiny microcontroller

Leave a Comment / AVR ATmega Projects, LED Projects / Ibrar Ayyub

A circuit that drives a red LED from a 1.5 volt battery and simulates an incandescent light. Duty cycle can be changed by selecting resistor values. Photo 1. This printed circuit board is 3 cm long. The first prototype was made with through hole parts. This is a single sided surface mount board with one

White LED Stroboscope

Leave a Comment / AVR ATmega Projects, LED Projects / Ibrar Ayyub

Finally, white LED’s are bright enough to use in a practical stroboscope. This circuit can operate as a bench-top stroboscope that, in conjunction with an oscilloscope or frequency meter and bench top power supply can accurately measure rotational speeds, or it can be operated hand-held from a single 9V battery, using a marked scale to
