Simple ATMEL AVR – Programmer

In this project we decide to implement simple ATMEL AVR microcontroller programmer for our hobby electronic purposes. We get ideas for this project from http://www.electronics-diy.com and http://www.societyofrobots.com. All the credits of this project go to them and creator of the ISP Programmer - Adam Dybkowski.

You can get complete circuit diagram from here

Entire project is based on the 7408 - Quad AND gate chip and it is possible to use any (CMOS/TTL) AND gate chip with this project. During the testing phase we use CD4071 and 7409 quad AND gate chips without any circuit modifications.

During the assembly process make sure to install proper heat-sink to the 7805 voltage regulator.

After constructing the circuit download and install ISP Programmer and follow these steps,

  • Open ISP Programmer software package and press "Setup" button to setup the programmer.
  • Select "AEC ISP" as a "ISP Cable Pinout" and press OK
  • Connect MCU to the programmer and power on the programmer
  • Select MCU type and oscillator (Crystal) frequency from the software
  • Press "Reset ON" button
  • Press "Read Signature" button

If the device and programmer is working properly ISP Programmer automatically detects the chip and flash memory configuration from chips signature bytes.

  • Now specify the hex file to ISP Programmer and press “Erase and Program All” button to start the programming process.
Note : During the testing/usage, some times we got “NOT KNOWN (FF, FF, FF)” as a device signature. If you get this error please check the following,

  • Programmer is connected to the computer and power on
  • MCU Crystal configuration

If ISP Programmer still produces an error, problem is in your MCU software. (Especially your MCU software produces output to the MISO and MOSI related ports.) Then disconnect programmer’s RESET connection from MCU and connect MCU’s RESET pin to the ground (0V) and continue your work. (Ignore the programmers RESET terminal)

This simple programmer support wide range of ATMEL ATtiny, ATmega and AT45x, AT89x and AT90x series MCUs.

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
