Week 14

This video describes the process of what currently happens when our groups Rube Goldberg Machines are connected.  Both circuits are started and finished with dominoes in order to give us flexibility within our group and in regards to the groups around us.

Video's two and three provide examples of our failures.  Initially, we took it upon ourselves as a challenge to use only one power supply (since they're so sought after for this project)! During the process of setting up our machine, we had to overcome some obstacles.  We learned about where to position our different structures and what order we needed to place everything.   Despite what we learned, we still experienced random error where suddenly one circuit would just stop working.  On our next attempt, we finally noticed the power supply changing upon the switching of the first circuit.  Between both circuits sharing one power supply, we were drawing too much to run our machine %100 of the time.

After switching to two power supplies, we found it rather easy to make it work!

Week 13

Week 13

Stocker Rube Goldberg

     Parts Used

  • Seven Segment Display
  • LM324 Op Amp
  • Relay
  • Transistor 
  • Motor
  • Capacitors
  • Resistors: Various Ohm Values
  • Dominoes
  • Solar panel
  • Timer
  • Counter
  • Logic Gates

Rube Goldberg Plan

      The setup I have chosen to use consists of seven segment displays, a relay, op amp, transistor, motor and dominoes. The plan is to get voltage from my partner next to me to flip the relay. I haven't figured out how I will get my voltage to start from his rube goldberg. I was thinking of using a solar panel like the project in front of me who I will have to connect with. From there it will light up the seven segment displays and go into the op amp. I plan on having around 1 volts go into the op amp and around 10 come out by using resistors to get a gain of 10. From the output of the op amp it will be sent to the transistor to power the motor. The motor will be used to spin and hit the first domino to create a domino effect. I will have the dominoes go up and over the desk to fall down to the other side. The person I will be connecting with will be using a solar panel and will have it covered by a sheet of paper. With the dominoes I will be able to pull off the sheet to get his circuit going. In my video it isn't exactly ten seconds because my second set of dominoes are two hours away and I wasn't fully able to get it to the time limit. Once I get my second set of dominoes I will be able to add a longer setup.



Update: I am currently working on extending the time of my circuit by adding a timer along with a counter to set off my RB process. I will have the timer be hooked up to the segment displays and once it hits a certain amount of time, it will be transferred to the opamp and relay to start the motor. 

Group Project:

Nicks circuit did not work out the way he planned and a part failed on Friday. We weren't able to produce a video of our setups connecting but it will be done by using dominoes. Once his motor goes off after his timer is reached his goal time it will cause the dominoes to fall and pull the sheet off my solar panel. Once the sheet is pulled off from my solar panel, my project will start its process.

Failures

       When it comes to using dominoes it is very easy to fail and knock them over. It happened to me a few times and also when the dominoes had to fall off the edge shown in my first video, the domino path didn't continue. Other failures involved the circuit with not putting in the correct resistor values to create the desired gain for the op amp. Also the resistor values for the transistor were off making the motor spin very slow and not hitting the domino over.
