Implementation Details

1. Gather Material needed listed on Specs

2. Attach the axles to the bottom of the base of the Kart. Use 4 screws on each axle to hold them in place. Put 2 of the screws on one side of the axle and the other 2 on the opposite side of the axle.

3. Attach the Wheels to the ends of the axles, be sure to use the Rubber pieces to hold the wheels in place. You will use rubber on the inside and outside of each wheel to hold it in place.

4. Attach the Battery to bottom of the Kart. You will use Duct tape to hold it in place.

5. Attach the Motor to the bottom of the Kart. Place the motor facing out, but in front of one of the Rear wheels, so that both the motor and wheel are rubbing together. This will make the wheel spin once the trigger is activated. You will use a couple screws to help hold the motor in place as well as duct tape.

6. Poke 4 holes through the Base of the Kart in order to run the wires through the base.

7. Place the Black Wire of the Battery and the Green wire of the Motor under one screw together and tighten the screw to hold the wires in place. Place a paper clip over the white wire and a screw over both and tighten it as well. Lastly, Place the Red wire from the battery about half an inch apart from the screw with the white wire and place a screw over it and tighten it as well. The Paper clip will trigger the motor to move the Kart once the Ideal weight is achieved, so place the paper clip over the screw with the red wire.

8. Put the walls up on the Cart. Use duct tape to hold the walls together.

(Ski Lift)-inator 

Problem: How can the extreme conditions of hiking up the mountain be reduced by a mechanical design?

  • The time and effort it takes in the hike of the mountain tires people to the point of exhaustion. 
  • The individuals are too tired to continue a second run at the slope.
  • Removing and making skis personal cargo will reduce the stamina of the individual trying to climb the mountain.
  • Skiing would be less enjoyable for individuals because of the extreme climbing conditions.

Solution: This ski lift will be designed to carry individual skiers up the mountain at designated areas to create an easy and comfortable transportation experience up the mountain.

Fabrication Process

Major Tools you need to complete the ski lift! 

  • Lathe
  • Drill or drill press 1/16”-1/2” drill bit assortment
  • Scroll saw
  • Hack saw

First you need

  • 2×32” pieces of 1/2” dowel rod
  • Small sheet of plywood to cut pulleys out of, no more than 12” in length and 5” in width, thickness about 1/2”-3/8”
  • 6ft of household string
  • One 3/8” brass bolt
  • 4” copper wire at 410MIL
  • Torch and solder
  • Compass
  • Base board
  • Small sheet of balsa wood

Step 1-

  • Get the compass and map 6 pulleys at 1” in diameter, and map 2 additional pulleys at 2” in diameter.
  • Using the scroll saw, cut along the lines you made with the compass, you should at this point have cut out 8 individual pulleys.
  • Cut the dowel rod to length; 2×7” pieces, 1×10” piece, 2×13”, and 3×3” piece.

Step 2-

  • Using the lathe, shave one inch in length from one end of the piece of each dowel rod and turn it down to 1/4 inch in diameter. Note: Only on one end of each dowel previously cut to length except the (3×3” pieces, they need it on both ends).
  • Using your drill press, drill 1/4” holes in all of the pulleys at the most centered point.
  • Using your drill press, drill 1/4” hole in the center of each 3×3” pieces, insure not to drill to close to either side of the dowel.

Step 3-

  • Get your base board, drill 1/2” holes evenly separated, N/A” between each post.
  • Assemble what parts you have. Put your 2×7” posts in the first two holes; in the middle hole put your 10” posts; in the last two holes put your 13” posts. Then on the three posts in between the two outside posts, apply the 3×3” pieces to the top of the posts.
  • Apply horizontally the 2” pulleys on the two outer most posts, then the other 6 vertically on the 3×3” track posts

Step 4-

  • Put the brass bolt in the lathe leaving about half and inch sticking out of the chuck. Take the bolt down to 4/16” at about a 3/8” in length. Using the drill press attachment on the lathe drill 1/16” hole in the center of the bolt.
  • Take the bolt out of the lathe then over to your dill press.
  • Using a small vice, hold the bolt as you drill a 1/16” hole into the side of the piece previously taken down to 4/16”.
  • Leaving it in the mini vice, go to your torch and soldering station. At this station you will need 1” of the 4” of copper in your supply list.
  • Solder the wire into the hole drilled in the side of the bolt, not through the center hole.
  • Using a hack saw, cut of the 3/8” piece with the copper sticking out the side of it.
  • Take the piece you now have and clean out the 1/16” hole using the drill press so the string will freely slide into the hole.
  • For the rest of the chair, cut off 4 thin strips of sheet metal at about 3” long and 1cm wide. Bend the sheet metal 90 degrees at one end of each piece about 2cm at one end of the bend.
  • Using a small 8 4cmx2cm pieces of balsa wood, glue together at a 90 degree angle on the bend put in the pieces of sheet metal.
  • Apply the strips of sheet metal to your copper wire pieces by bending the tip not connected to the chair portion of the metal.

Step 5-

  • Connect all of the pieces made in step 4 to your 6 foot string and apply that to your pulley system using own judgment on how tight the line should be.
  • Insure that your chairs are somewhat evenly spaced and permanently attach your chairs with hot glue or some sort of adhesive.
  • Insure that your pulleys spin the string which in turn spin the chairs.

Step 6-

  • Applying the motor (picture bellow of how to configure the motor system)
  • All pieces in the gearbox are adjustable for human error, yours will line up differently but glue the gears in place as needed for the least amount of friction

Problem: Some people are unable to manually wheel themselves in a wheelchair.

Solution: We will build a motorized wheelchair. []

We are going to build a wheelchair that will move forward due to motor power. The goal is to make a functional chair that moves at a decent forward pace. We want the wheels the to be stable and not wobble. We would like to incorporate a good amount of the specifications we have written out including a seat cushion. Our wheelchair will be on a smaller scale than a normal wheelchair for a human.

Team Members

Our team members did a little bit of everything:

  • Brainstormed ideas for the chair
  • Built Chair
  • Wired the motors
  • Built the wheels
  • Cut out foam for chair



Implementation Details

First we nailed two pieces of wood to make an L shape for the basic chair shape. Next we nailed two more pieces of wood on the sides to make arm rests. We then made the wheels with using metal rods, cd (for the back wheels) and plastic discs (for the front wheels) and caped the ends with rubber tubing. Then we placed nails around the area where the batteries are to hold them still. Then we used screws to connect the wires of the batteries and motors together leaving a gap in the circuit. We then places a paper clip touching one screw and hovering over another so we pressed the circuit is completed. We then used two nails towards the back to hold the axel of the back wheels and attached a rubber band nailed to the front to created tension. Then we used two pieces of foam and placed a rubber band around the axel and ran it over the top of the seat to hold it against the pieces of foam. The motors were then super glued to the base tightly pressed against the wheels. Finally we stapled foam to the seating area for “comfort”.

Problem and solution

Regardless of how long your flight is, coming off the airplane leaves many feeling physically and mentally exhausted. There are numerous stress factors that coincide with traveling by flight, which can include complicated and long layovers, switching airlines, re-checking in through different terminals and etc., this can all be made a little bit easier by adding in a hassle free and productive method of transporting people through the airport in an efficient way. For example, by adding in a moving sidewalk to each terminal, traversing across to different gates / baggage claims can greatly reduce the time and stress it takes for tight layovers; and even make just getting out of the airport faster to a stress free environment an easier and faster process.

 Local children of Wichita, Kansas were at the playground and they really just wanted to get dizzy. The only problem was that their playground had not been upgraded in years. They needed to fulfill their desire for dizziness and there was only one group of guys that they could call, The Troubleshooters.

Being kids ourselves at one point, and maybe one of us still being a kid at heart, we knew what this playground was missing. They needed what us as children had to spin on back in our glory days, A Merry-Go-Round

Implementation Details

  1. First we started with the a bock of wood, some screws, a motor, a 9V battery, paper clips, and a connector. We screwed the red wire from the connector into the wood while also screwing in the green wire from our motor.
  2. We then screwed the paper clip and the black wire from the connector into the wood where the wire and paper clip are touching.
  3. Next we screwed another the white wire from the motor into the wood with the other paper clip also touching.
  4. From here we bent one of the paper clips to where when you pushed it down it would touch the second paper clip and start the motor.
  5. Then we plugged the 9V battery into the connector.
  6. Then we started construction of our actual merry-go-round.
  7. We took 2 cd’s and super glued them together with a circular piece of foam in the middle.
  8. Next we constructed our bars and safety cage with pipe cleaners in a design that we personally found suitable for safety.
  9. Then we put our motor into our gear box and put 3 gears into the gear box in order to slow down the number of revolutions so kids wouldn’t die.
  10. For this to actually let the motor spin we had to place two spacers in the gear box to spread apart the 2 platforms of the gear box.
  11. Then we placed our merry-go-round on the pole sticking up through the gear box that would be spun by the final gear.

 A device to produce repeated mooing sounds when a door is opened

In many businesses where employees need to be aware of the presence of customers, a door chime is employed. Were this store to sell cow related items it would ofcourse require a cow themed door alarm. Our Door Mooer is designed to produce continuous mooing sounds when a door is opened, through the use of a contact switch, a motor with gears, and two mooing cans.

  • Michael constructed the contact switch and wrote this blog post
  • Adam provided moo cans
  • Chandler made the video
  • And we all worked on prototypes


  1. we started by creating a contact switch consisting of a wooden tongue depressor, a small foam square, rubber bands, and aluminum foil
  2. the wood is mounted on the foam and then the door frame with glue/tape and the rubber bands are connected from the end of the wood to the near part of the door. Aluminum foil is applied to the wood and to the door frame and the wood so that when the rubber is stretched they make contact. They must then both have wires connected
  3. on a raised platform, a gear train going from high speed to high torque is mounted high enough to give the moo cans clearance
  4. a wooden bar is placed between the gear train and a support, and moo cans are glued to either side. When the contact switch is closed, and the board is properly mounted, it should rotate and make repeating moo sounds.

The Cloudy Past and The Bright New Future

Ideally every child should have the opportunity to enjoy the awesomeness of the playground swing. This experience should not be taken away by the lack of friends to push them around or the the lack of attention from parents and definitely not by the fact of having small legs. The truth is that  many children have little- if any- memories of playing on the swing and many of those memories are sad because of the difficulties that was preventing the child from being able to swing. But no need to worry anymore! The Never Alone team is here and we have brought you the Automatic Playground Swing Set! It is a regular swing but built  for those children that do not have any friends or attentive parent. The swing has a motor with a button that can push the child at a safe speed and ensure the child enjoyment. Say goodbye to those horrible swing memories and hello to your new favorite friend: The Automatic Swing Set!

Problem and Solution     

     Though smoke alarms prove to save lives by alerting the house occupants to an emergency situation, sometimes they are falsely triggered. An example of this would be while cooking and burning food which would produce smoke, but not necessarily be life threatening. The result is an ear piercing annoyance while trying desperately to get rid of the smoke.  In our collective experience, we all agreed we have seen or actually been in risky situations to try to stop the smoke alarm. Frantically waving towels, standing on counters or chairs is undoubtedly not the way to stop the maddening beep. Team Avengers engineered a packaged solution to retrofit the smoke alarm with a housing unit to safely fix a “false alarm” without interfering with the intended design.   The solution is comprised of a 3″ fan, 9 volt battery, duct made from a light-weight plastic funnel, screws, paperclip, wire, blank compact disc spindle and glue.

Team Members

Our group did not necessarily have any assigned roles, we worked together and shared most of the responsibility equally.

  • Drew: Did most of the building and brought many of the materials in
  • Bobby: Had the original idea and did much of the building
  • Larkin: Created the video and the first design ideas
  • Marlo: Helped with building and created the report
  • Muhammad: Helped with building and the report


Implementation Details

  1. First get a 3″ fan, 1″ thick plywood, one 9v, switches to run the fan, a paperclip, funnel, two screws, a CD spindle, and hot glue.
  2. For ease of transporting, cut a hole 3″ x 3″ into the plywood to insert the fan snugly.
  3. Attach a switch to the plywood to run the fan: Using wires from the fan leads, create a switch by screwing the end of the leads to the board approximately the distance of a paperclip and then fashion a switch by connecting the battery leads to each screw and then the paperclip to one, bend at a slight angle to not make contact while unattended. The paperclip will touch down to complete the circuit and when released it returned to its disconnected state.  
  4. The fan/switch board will be secured to the intake end of the funnel via hot glue or other molding compounds.
  5. Mount the battery near the switch
  6. Measure the lightweight plastic material used for the funnel by first measuring the outside diameter of the fan for the intake portion of the funnel and secure with utility tape.
  7. Resize the outtake portion of the funnel to approximately 1.5″ and secure with utility tape.
  8. Use scissors to flush the ends of the funnel after resizing.
  9. Get a plastic CD spindle, the kind used for recordable CDs and separate each part into two pieces.
  10. Use a utility knife to remove the top and bottom of the cylinder portion of the CD spindle to create the main housing unit.
  11. The actual spindle of the CD holder needs to be removed and can be done so using a lathe, only the outer portion of the bottom needs to be used.
  12.  The small wring of this housing unit which provides the tension clips for the outside “cylinder” piece can be used to anchor around the smoke detector with common sheet rock wedge screws. The current prototype does not include sheetrock screws for mounting the housing unit around the smoke alarm.
  13. For the funnel itself, use a fine-tipper marker to trace the desired shape onto the outside cylinder portion and use a dremel tool to achieve the hole.
  14. To create a horizontally narrowed wind output, we squeezed the appropriate end into the cylinder unit hole we made with the dremel

Paraplegic individuals can’t feed themselves

Our goal was make a machine that made it easier to feed paraplegic individuals and others who can not fend for themselves.

  • Cheez-Its will be poured into a funnel then will fall onto a rotating wheel. 
  • A conveyor system will carry food to the individual in need of assistance.

This makes it easier for the care taker to feed and not have to worry bout running back and forth from the kitchen to the room where the said individual is residing.
