Work on the PiTagErrUs resumed by adding parts to the forward array. All of the LEDs were held in place by pushing them partially out of the holes, affixing the plastic LED clips then pushing the clip into the hole where they would lock in place.


Four forward arrays were completed. All the components, screws, lenses, and LEDs were attached. It should be noted that the holes drilled for the LED holders were 9/32" (7mm) which was two standard drill bit sizes up from the 1/4" (6mm) bits used previously.


Infrared sensors were glued to the front of the forward arrays with ordinary super glue then held in place with rubber bands while they dried.
