Modified AA-Battery Pack and 9-Volt Clip Combo:

This AA-battery pack has been modified to include the ground of the 9-volt battery clip. The switch on the AA-battery pack connects the ground wire from the 9-volt clip and the AA-battery pack's ground to one common ground. This is great for controllers like the OOPic. The AA-battery pack can provide power to your servos while the 9-volt clip can supply the OOPic or any other controller with power and since the ground is shared between the two battery sources, your servos will function properly! This is the same power supply used on the NewCDbot!

Pair of 1-3/4" Diameter Foam Wheels:

These foam wheels are great for that small robot you are building! Simply drill or poke holes for mounting to your servo, screw it onto your servo horn and you are done! Two 2-56 screws and two flat washers are included with each wheel! If you have access to a 2-56 Tap then it will be easier to screw in the 2-56 screws, but I have been able to screw them in without tapping the servo horn. Two of these foam wheels are used on the NewCDbot.
