This simple microcontroller programmer can progam most of the 89 likeAtmel' AT89S51, AT89S52, AT89S53, AT89S8252, AT89S8253 including the Atmel AVR series of microcontroller. It simply consists of an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed.
Features
- Works under multiple platforms. Linux, Mac OS X and Windows are tested.
- No special controllers or smd components are needed.
- Programming speed is up to 5kBytes/sec.
- SCK option to support targets with low clock speed (< 1,5MHz).
Simple Steps to made This programmer
Step 1:- Step 1:-
Download:Firmware and circuit
The following packages include circuit and firmware.
Firmware is the software which going to be burn into programmer's microcontroller, this firmware have code to enable the programmer to communicate with pc via usb and target microcontroller

source code of the firmware also avaible on request to any one who is interested.
Please refer to Readme.txt for details on building, installing and using USBasp.

Step 3:-
PCB and Part Soldering:-
You can create your own pcb using any PCB editor like eagle, OR you can solder the circuit a general purpose pcb, You Can also Use PCB created By me Click here to dwonalod my pcb design
Step 4:-
Getting The Atmega8 Microcontroller Ready To be used as a programmer:-
Note:- Make sure you burn the right fuse bit configration along with the firmware into atmega8 microcontroller
for atemega8 the fuse bit are
atmega8 HFUSE=0xC9 LFUSE=0xEF
if you have a problem how to burn those fuse bit use the give serial avr programmer then please visit serial avr progammer page for detailed information
Step 3:-
PCB and Part Soldering:-
You can create your own pcb using any PCB editor like eagle, OR you can solder the circuit a general purpose pcb, You Can also Use PCB created By me Click here to dwonalod my pcb design

Getting The Atmega8 Microcontroller Ready To be used as a programmer:-
Getting the atemega8 microcontroller ready to be inserted into the newly soldered pcb ,and start working. you have to burn the firmware which you just downloaded in the Step 1 into the atmega8 microcontroller. you can use the serial avr programmer to get this job done.click here to know about how to make a serial avr progammer and how to program the atmega8 by using a serial avr programmer.
for atemega8 the fuse bit are
atmega8 HFUSE=0xC9 LFUSE=0xEF
if you have a problem how to burn those fuse bit use the give serial avr programmer then please visit serial avr progammer page for detailed information
Step 6:-
Driver installation on a PC:-
At the first time when you connect your programmer to the pc your programmer will be dected as usbasp and you have to provide a proper path for drivers to be installed.this programmer use same driver as my privous usb avr programmer use
 |
| USB AVR prorammer Dected By the widnows |
 |
| Give the Instruction for a specfic location driver installation |
 |
| Give the path for driver to be installed |
 |
| USB AVR Programmer installed |
 |
| USB AVR programmer is being connected and shown in device manager |
On Linux and MacOS X no kernel driver is needed.
Windows requires a driver for USBasp: usbasp-windriver.2009-02-28.zip (70 kB)
Note: Windows Vista/7 x64 requires drivers with digital signature. Currently there are no official drivers for libusb (USBasp software is based on it) with such a signature. Users reported that there is a tool named "Driver Signature Enforcement Overrider" to avoid the signature check.
Step 6:-
Programming the other microcontrollers:-
You can use Progisp software to burn the hex file in to the traget microcontrollers.note: i don't suggest you to use any other sofware then the progisp. but if this works with any other then you are free to use that.

Schematic
Connections to the traget microcontroller:-
* you can programe may microcontroller by using this schematic , all you need to do is that find out the data sheet of that mcu you want to program and check the pin configration. and the look for PIN MOSI MISO SCK and Reset , the connection will be as follows
if sombody face any trouble then please let me know
