Mars Rover Autopsy

After having built the RC Rover based on a cheap New Bright RC I would make these recommendations. The Arduino tie in portion was easy, I would use two PING sensors so it can actually detect a cross section of an area. This would allow it to negotiate crowded areas better.

The $30 Dollar Mars Rover

So here is the fun project for Sunday. I have enclosed several pictures of components to be used in developing a cheap rover. This little guy should be able to move around a room and avoid basic objects. The fun part is I am going to show you how! But, for tonight can you figure […]

PCB Laser Toner Method

The easiest way I have found so far to make a PCB is to use the Toner Transfer method. You will need some basic supplies to include the following items to complete this task. [singlepic id=1 w=320 h=240 float=center] [singlepic id=3 w=320 h=240 float=center] [singlepic id=5 w=320 h=240 float=center] The above three items in include […]
