Jawa Ionization Blaster

Jawa ionization blasters were built by the Jawas who lived on Tatooine to capture droids. The guns themselves were cobbled together from whatever scrap the Jawas could scavenge. The gun was made of a blaster rifle stripped down to its power pack, and then had its components replaced with an ion accelerator which was created using a droid restraining bolt and an accu-accelerator from a capital ship ignition system.

R5-D4

R5-D4, also called "Red" by Luke Skywalker, was a red and white-striped R5 astromech droid owned by a group of Jawas on Tatooine in the early days of the Galactic Civil War. Shortly before the Battle of Yavin, the Jawas attempted to sell him to Owen Lars, but the droid purposely malfunctioned his motivator at the advice of R2-D2, so that Lars could purchase R2-D2 in R5-D4's place.
