Your robot army, controlled by Arduino and Bluetooth
- noonespecial 14y agoUbiquitous wireless connectivity at "disposable" prices is a looming killer app for makers. Less than 2 years ago, putting a project "on the net" cost in the neighborhood of $100. You build an entirely different kind of project when its temporary because you have to move your super expensive wireless unit around between projects. Somewhere around $20 seems to be the "disposability" point. Everything gets interesting after that.
