AVR High Voltage Programmer 2

AVR-HV2 is Arduino based high voltage parallel programmer for AVR microcontrollers. This programmer can read, write, and erase both flash memory and EEPROM. Also, this can use to set fuse bits of AVR MCUs. Compare with the previous version of AVR HVPP, this design is based on commonly available components with a simple schematic. In this release driver software is also rewritten to provide cross-platform support.

AVR-HV2 shield with Arduino Mega 2560 board.

AVR-HV2 programmer is designed as an Arduino Mega shield. Dimensions of the AVR-HV2 are similar to the Arduino Mega board. It can be powered using a power source connected to the Arduino Mega board. The suggested power source for this programmer is a 12V 1A DC power adapter.

The control software of this programmer is design to work on both Windows and Linux operating systems. It supports the import and export of memory data in the Intel hex file format. The communication link between the programmer and the control software is established through the USB port.

The current firmware and control software of this programmer supports most of the generally available AVR MCUs which including ATmega8, ATmega328, ATmega32, ATmega16, etc. The AVR MCUs with extended addressing modes are currently not supported.

The PCB board used in this project is sponsored by the PCBWay. Overall the PCBWay provides excellent support to fabricate this PCB. We got finished PCBs within 3 days and the quality of the service and products they offer are at a superior level. PCB of this project can directly order from PCBWay through this link.

Linux version of AVR-HV2 driver software.

This is an open-source hardware project. All the design files, documentation, firmware source code and compiled binaries are available to download at the project source repository.

CD2003 - yet another simple FM radio receiver

In the last few days, we are looking for some simple FM radio receiver to integrate into one of our ongoing projects. For that, we try several FM radio receiver ICs including TDA7000, CD2003/TA2003/TA8164, CXA1019, and KA22429. Out of all those chips we select CD2003 (or TA2003/TA8164) based receiver for our project because of its simplicity and outstanding performance. Except to CD2003, Sony CXA1019 also perform well but we drop it because of its higher component count. We design our receiver based on Toshiba TA2003 datasheet and later we try TA8164 and CD2003 with the same circuit. Either CD2003 or TA8164 can directly replace TA2003 IC, and as per our observations, TA8164 gives excellent results out of those 3 chips. A prototype version of CD2003 FM radio receiver The PCB design and schematic which we used in our prototype project are available to download at google drive (including pin-outs of crystal filters and inductors ). Except for CD2003 IC, this receiver consist

Arduino superheterodyne receiver

In this project, we extend the shortwave superheterodyne receiver we developed a few years ago . Like the previous design, this receiver operates on the traditional superheterodyne principle. In this upgrade, we enhanced the local oscillator with Si5351 clock generator module and Arduino control circuit. Compared to the old design, this new receiver uses an improved version of an intermediate frequency amplifier with 3 I.F transformers. In this new design, we divide this receiver into several blocks, which include, mixer with a detector, a local oscillator, and an I.F amplifier. The I.F amplifier builds into one PCB. The filter stage, mixer, and detector stages place in another PCB. Prototype version of 455kHz I.F amplifier. In this prototype build, the Si5351 clock generator drives using an Arduino Uno board. With the given sketch, the user can tune and switch the shortwave meter bands using a rotary encoder. The supplied sketch support clock generation from 5205kHz (tuner frequ

Calculator for audio output transformers

Audio output transformers are heavily used in a vacuum tube and some (older) transistor base audio power amplifiers, but these days output transformer are quite hard to find and expensive item. For homebrew projects, the best option is to construct those transformers by ourselves and this script helps to calculate winding parameters for those transformers. This " AF output transformer calculator " script is written using Python and it works with most of the commonly available Python interpreters . The script is available to download at google drive under the terms of GNU General Public License version 3.0 . Homebrewed 25k: 4 output transformer Once supplied the input parameters this script provides a winding ratio, the number of turns required for primary and secondary winding and required copper wire gauges for both primary and secondary windings, etc. We construct several AF output transformers based on results of this script, which including transformers for M
