Let's Make Robots!


I dont know how to u se it or what it can do but can i use it in any way.

It was found in a old DVD player that the laser was failing so I took it apart.

Any info maybe how i could program it / use it would be very helpful.

thank you

You tried to search google for a datasheet? That is all we would do to help.

After long search I found this 

and this was on a pdf file for EN29F040

I forgot to mention that I have neaver programed a thing so i am an abusulote noob at this kinda stuff

Just because I found this in a DVD player thats what got me intrested

And if you have some easyer chips to start of with that do not cost alot i would try but I am in school and dont have a after school job that i could use to pay for something expensive.

It says at the top its Flash Memory, so it stores info that other chips can access. It`s not much use by itself.

An arduino or picaxe starter kit would be a good way to dive in to micros, or if you`re *reallY* tight on money check out this instructable.
