Chess Board Only no engine

where can we get a chess board with pieces only, electronic,

I mean where i can put the pattern I want and play both sides black and white myself,

like if i have a real chess set and i want to freely put the pieces on it,

thank you

Question is, why should it be electronic? 

ok, to use it at breaks while at work, simply

I repeat Mana's question.  Why does it have to be electronic?

Your reply doesn't make any sense to me.  You can use a regular chess set "at breaks, while at work."

Anyway, Barnes and Noble sells them...
The USCF sells them...
Walmart sells them...
Amazon sells them...

Just type in "electronic chess set" in Google.  You'll have your hands full looking at all the links that are returned.
