Step 5: Hub Box Preparation

Materials: Hub Box, Drill, (Tape, Ruler and Sharpie can be used to center holes)

a. You will have to drill 5 holes in the Hub box
b. Lay out all of the components inside of the box before drilling anything. This will ensure that everything fits in the way you want.
c. Drilling tips:
     i. Make sure the drill bit you are using is smaller than the hexagonal nut and the round housing of the jack. The nut and housing will compress on opposite sides of the hub box to hold the jacks in place.
     ii. If you drill the hole too small you can always make it bigger.
     iii. When you have your layout, use tape on the outside of the box so that you can easily mark the hole positions.
     iv. See the picture of the hub box layout to see each hole’s recommended position. These positions will vary depending on the box’s position on the wheelchair.
     v. Note: The charger power jack and switch cable jack should be next to the fuse and the camera jack and monitor jack should be next to each other on the short side of the hub box.
d. Drill 3 holes for the power jacks (one for camera, one for monitor and one for charger). Size: ½ in.
e. Drill the hole for the fuse holder. Size: ½ in.
 f. Drill hole for switch cable jack. Size: ¼ in.
g.Once all your holes are drilled, install the jacks with the supplied hex nuts.
Fantastic idea mirrors would not work for me I know I did try anything that adds to the width of your chair makes your day 10 harder and I had no hand strength to move it I'm lucky in a way I have my husband with my most of the time and he can direct me well but it is hard going backwards blind! This would be a wonderful solution maybe the monitor could be dual purpose too set it up to watch films during long hospital waits thank you for the inspiration
I like your project, congratulations are in order. However, I reeeally think this is a super-expensive, over-engineered, time-consuming project. No need to put a system that will add weight and empty the parent's pockets when 2 mirrors can do the trick, and may work even better, just like in cars. &quot;Ockham's razor&quot; if you will.<br><br>I think this is a great Proof-of-Concept project, but nothing else. Practicality it's not it's strongest. Much congratulations and respect anyway. Take care.
Just like in cars, a user must turn their head and sometimes even their body to see those spots a mirror does not cover. Many people in wheelchairs do not have this ability. Convex mirrors, to get a wider view, are not practical because the distance are warped. also the angles required to see behind you mean very wide or awkward placement.<br><br>Perhaps you should look into what the needs of the person using the chair might be before you make uninformed comments. I think that their project was a brilliant use of newer technology and is probably a LOT less than a similar system would be if offered by the medical establishment. I have worked in that industry and was shocked to see things cost three to five times what they would normally be worth... for identical items... only because they were called &quot;medical&quot; equipment&quot;.
Thank you for your support! You rock!
Our Girl Scout robotics team came up for the idea for this project and implemented it with assistance from CATEA at Georgia Tech (thank you!). It is true that mirrors are less expensive. However, they stick out to the side of the wheelchair and make it difficult to get through doorways without folding in the mirror. In the case of one of our friends, she does not have the strength to fold in a mirror by herself, so a mirror would limit her ability to get around on her own. Mirrors require the user to look to the side to see the mirror, which is not possible for some wheelchair users. Also, mirrors can have blind spots, which is one reason why backup cameras are becoming increasingly popular on vehicles.<br><br>The backup camera system does not add a lot of weight to the wheelchair. The monitor can be mounted so it doesn't stick out past the arm of the wheelchair, so getting through doorways is not a problem. The monitor can also be positioned so the user can see it without turning their head.<br><br>Both of our friends really like their camera systems and find them very useful. Quinn had to have his removed temporarily when he got a new seat and he was eager to have it reinstalled on his new seat. Quinn had tried mirrors in the past, but he stopped using them because they got in the way. We hope others will find these instructions useful. If anyone uses them to install a camera on a wheelchair, we'd love to hear about it.
great instructible!
absolutely brilliant!!!
Yet another awesome project out of Georgia Tech! Thank you for using I'bles to document all of this great stuff, so that others can benefit :-)
