Transform a cheap RC Transmitter with Custom Firmware using ATMEGA64 Microcontroller

Leave a Comment / Using Atmega / By

The Turnigy 9x is a cheap Chinese radio transmitter widely sold by hobby king and other retailers under a variety of names. This is a computerized radio transmitter and is already a great deal for the price ($53 currently) and pretty capable if you can figure out how to use the stock firmware. The microcontroller running the show is …

AM radio transmission using AVR using Atmega324 microcontroller

Leave a Comment / Using Atmega / By

When you think about building a radio transmitter circuit, the first thing that comes in mind is it requires too many analog components. But wait a minute, this guy demonstrates an AM transmission using a microcontroller. The interesting part is it uses a plant as an antenna for transmission. This project is based on Atmega324 …

Broadband RF Field Strength Probe using Atmel AT90S1200A AVR controller

Leave a Comment / Using Atmega / By

Download auto-zero assembly code This broadband probe has a small antenna (about a 15 cm length of insulated wire). Radio Frequency energy coupled to the antenna is detected and made available to drive millivolt level signals to the input of a DVM (Digital Volt Meter). Its battery powered for convenience with very low current drain …

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

Leave a Comment / Using Atmega / By

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 …
