The last "big" issue on our list for the audio/video system is creating the "mid-frame," a middle structure that serves as both an amplifier rack for the sound system, but also a helps blend the shape of the subwoofer enclosure with the middle section of the Eclipse. Last year, we ditched the rear seats in order to make more space for the TV and amplifiers. Now, the trick is trying to use that space both practically and esthetically.
First, we designed and built a wedged shaped panel that would sit in the back seat area just in front of the TV...but it didn't seem to complement the curved nature of the sub box...
So we removed it and headed back to the drawing board for some other ideas on what panel would create the mid-frame...
In the meantime, Car Club students tended to several other jobs in and around the car.
Two senior students helped secure the TV support bracket onto the chassis, as it tended to wobble when the TV was motorized:
SHSM students helped diagnose and narrow down a raised panel on the rear hatch cover which was not letting the hatch close properly over the sub box. An easy fix! That student cut out the raised portion and installed a flush panel which will soon be fibreglassed or carpeted over to give uniformity to the hatch.
Two more students worked on enlarging the factory speaker brackets for the rear 6x9s. The original 6 inch speakers will be replaced with much more powerful Kicker Audio speakers.
The following week, we finalized an idea for the mid-frame. A flatter panel was to be constructed, recessed under the TV and stretch across the former rear seat area.
But in order to create this panel, we had the tedious job of creating and carpeting a rear seat area cover, to hide the fuel tank access plate and body wiring.
Additionally, the entire linear actuator system had to be moved rearward and bolted tightly so as to make space for the new carpeted floor plate.
With these adjustments made, and the actuator travel reset, we could install the new mid-frame.
Another couple of students removed, cleaned and painted the rear speaker grilles, to match the school's colours.
As a nice touch, Car Club's senior students helped install and carpet last week's flying frame with large new "B R" initials.
We previously had contemplated smaller initials, but the new bigger CNC-made initials have a better look!
Next week, the mid-frame will also be carpeted before we lay out the entire electrical system for the Eclipse's audio and sound components.
We decided to extend the mid-frame's top banner for a special component that's sure to get attention from onlookers...
With the mid-frame and flying frame nearly complete, we decided to create a special light-up sign that will be visible at night between the front seats. After digitally carving a recessed front panel and some painted acrylic in Mr. Mule's room, we will get out the Arduino boards and devise a way to create a fading red BR sign for the car...
Our prototype will soon be ready for testing and carpeting before it is installed in the car.
Join us on our next update where we tackle final carpeting and construction of the tail panel where our wireless keyboard will sit.
We are switching gears in room 114, and Mr. DaSilva is proud to be teaching the kids of Car Club and SHSM how to take something old and give it new life again!
See you next time!
