The Sonic Screwdriver is a rechargeable version of the normal Screwdriver. Like the screwdriver, it is used to alter the orientation of logic gates and machines from RedPower 2. Both the sprite and the name were inspired by the British TV show Doctor Who. The sprite appears to be of the 11th Doctor (Matt Smith)'s screwdriver.
It is recharged using Blutricity. One way to do this is to place a fully charged BT Battery next to the Sonic Screwdriver in your hotbar, and right-click with the BT Battery in hand. They cannot currently be charged by placing them into a Battery Box.
