Combo Lock Pick

Week0 Narrative
I revived my hinge and wood block from last class. The hinge is to be used to fold the combo lock pick to a position to work then fold it back to a resting position. I was given a block of wood and a door hinge to work with.  File:Door hinge shut.JPG|Door hinge is in a closed position File:Wood block for combo lock pick.JPG|Used to mount the combo lock pick File:Door hinge open.JPG|Door hinge is in an open position 

Week1 Narrative
The first thing that I did was screwed two blocks off wood to the door hinge. However this became problematic because the hinge did not extend to a full 90 degrees angle, so I cut the wood at a angle to get the hinge to extend to 90 degrees. The next problem was that there was a problem extending the wood back because the platform of the hinge was getting in the way. To fix this I cut a block out of the wood. After doing this the hinge could extend in and out with out a problem. After the blocks off wood were screwed in I screwed the wood in that already had the lock and device to pull the lock on it.

File:Extended view.png|The hinge allows the lock pick to be folded into a working and non-working position.  The next problem was how to connect the rubber holder to the gear on the motor. We were not allowed to take the gear off of the motor, which would of been the easiest way to do it because we could attach the rubber piece directly to the motor. So we found a gear that will link to the one ion the motor. But the hole running through the middle is way bigger then the bolt we have running through the middle. We did not want it to be lose or crooked so we attacked another one to the back that had a hole the size of the bolt. This gave it more stability.

File:Gears finished.png|The gears after the washer is put in.  After making the gears. I needed a place to hold them up. So i drilled a hole into the bottom piece of wood. The whole project was off balance and it kept falling over so to fix this problem I took two pieces of wood and screwed them to the bottom. This holds up the project nicely, and now when the hinge is pulled back it doesn't make the project fall over.

Week2 Narrative
The gears were not designed the best way. They could not continue to spin back and forth. I had the idea to place a bearing on one of the gears. We had to find a different gear that had the right size plastic hole, so that the bearing could be pushing into it. The out side of the bearing can be held in place while the inside which is attached to the gears can continue to spin. A screw is placed through the other gear. This screw goes through both gears and screws into the bolt attached to the plastic holder. The back gear is the gear that has the same groves as the gear on the motor, and the other gear is used to hold the bearing in place.

Using a piece of metal it was able to be bent into a hook shape. Using this the bearing can be placed in this and the gears should be sturdy and able to be held up.

Week3 Narrative
While trying to fix the original board that i had on the project it broke in half. Because of this i decided to restart building the whole thing. I used bigger boards to stabilize the project. A grove was cut into the bottom board, this is used to rest the hinge in. This is what i was trying to do when the first board broke. I next added a thin piece of wood under where the hinge is screwed in. This is to push the hinge forward because it is not at a 90 degree angle when it is fully extended.  File:Bottom board broke.JPG|The bottom board broke when I tried top cut out a bigger hole in the top to rest the hinge in. File:Side view of wood under the hinge.JPG|The wood pushes the hinge up to extend the hinge further to try and get it to a 90 degree angle. File:Bottom view of wood under the hinge.JPG|The wood pushes the hinge up to extend the hinge further to try and get it to a 90 degree angle. File:Both boards attached to hinge.JPG|Both boards attached to hinge. File:Board with lock.JPG|The board with the lock is attached to the upright board. The upright board isn't all the way to 90 degrees but the nuts on the back of the lock board push it out to a 90 degree angle.  I screwed in boards to the bottom of the plywood. This is to hold up the project. This is needed because the hinge makes the whole project off balance. The wood added makes the project very stable. But the next problem is when the locked is being pulled up the, thing doing the pulling is very violent. This is a problem because the board that is upright because of the hinge could fall over. To solve this I screwed in two smaller blocks the the back of the plywood. When upright these should hold the lock board up. Then when the board with the lock on it wants to be pulled back the smaller blocks can be twisted to the side, allowing the board to be pulled back. However when these blocks where screwed in they could rotate, but the blocks are too tall, therefor they are getting in the way of the lock board being pulled back .To solve this problem is cut the tops off the blocks off, letting there be more room for the lock board to be pulled back.

Right now they are upright to hold the board up. File:Sideways cut blocks.JPG|The turn able blocks are cut to allow the lock board to recline. File:Lock board reclined.JPG|Lock board reclined.  I found a board with a bearing in it. This is similar to the last idea that we had of using a bearing. The board was cut and screwed into place. A gear that is the same size as the hole in the bearing is put in it. The other gears fits around the fist gear and a bolt runs through the rubber stopper and all of the gears. Washers are placed on both sides of the bearing, and on both ends off the gears,where the nuts are. A problem with this design is that when the gears are turned the nuts loosen and tighten. This is why the washers are added. They are supposed to prevent this. Another problem is that the screw head inside the rubber is too big. This is a problem because the rubber can not grip the lock anymore. To solve this the bolt head is filed down. <Gallery> File:Bearing inside board.JPG|Bearing inside board.

Week4 Narrative
preferences: 1.Combo lock Pick 2.music project 3.tri bot

The Bearing was alittle off to the side bvecause of this the rubber would slid on and off the lock. The was an easy fix all i had to do was unscrew the bearing board and re-align it with the lock. After this I thought of a new idea of how to get this project to work. I decided to take a screw that was a little bigger then the hole of the gear. I would screw through the rubber and the gear to make a bond between them. If the gear moves then the screw will move. If the screw moves then the rubber holder will move. <Gallery> File:Bearing re-aligned.JPG|The bearing board was a little off to the side so it was realigned to be right in front of the lock. File:Side View of New Design.JPG|Screw running through the gear. The longer part of the gear goes into the bearing. File:Front View of New Design.JPG|Screw head is all the way in the rubber so it doesn't get in the way of the lock. File:New Gear Design.JPG|A larger screw is screwed through the rubber and gears to make them attached and to move as one. </Gallery> Video of the old design, there was problems with the gears being inline. Because of this the rubber would slip off at times then catch back onto the lock: http://www.youtube.com/watch?v=MT3pteALlsQ&feature=youtu.be
