Lets Start-Usbasp


A good place to start learning electronics and micro-controllers is by constructing a programmer.A programmer is basically a board which will burn program files(hex files) into a micro-controller .The usbasp is one such programmer which can be used to program micro-controllers, and this is how we started learning for the project.The usbasp is a universal programmer for atmega microcontrollers .The usbasp uses an atmega8 burnt with the usbasp hex file.The schematics for this is available here, this even contains the hex file to be burnt in the atmega8.It is advisable to use Eagle to view the schematics.Here is the pic of the first usbasp we made:

As u can see that the board doesn't look tidy and compact.Even the soldering has same state but this is the first board we made and so we had a lot of scope to improve.Of course we learned a lot of things from this preliminary board and enjoyed constructing it.The crystal oscillator with its two capacitor makes an important block. In the second usbasp board we rectified the mistakes made in our former attempt.We made it more compact and neat. 




Stay tuned for the next update.There lots out there :).
