Arduino Design Contest

This event is a heavily modified version of last years grab bag. The competition is sponsored by Union Pacific. Here is a quick rundown of how it is going to happen.

  1. We give you a list of problems to solve
  2. You get excited and write a short proposal
  3. We give you a parts kit
  4. You make a solution and come show it off sometime towards the end of April
  5. You walk away with sweet prizes and a smile
Who can participate?

The competition is open to ALL UNO students but is targeted at IEEE members and computer/electronic engineering skills will be useful. That being said there are only 20 kits available. IEEE members will receive preference. After that it is on a first come first serve basis, assuming your proposal is up to par.

Proposals

The proposal should be a half to a full page in length. Get yours in asap. Email them to pki.ieee@gmail.com as a PDF. The proposals show us that you are interested and have committed some time to this before we just hand you an impressive bag of parts. They also ask you to think about the larger picture, how a product would fit into a business, not just the technical design.

The proposal should include a description of the technical solution along with a business case for the product. This should include who is building the solution now, the production costs, what the market is you are going after, and how your product addresses their needs.

Problems

The problems are railroad specific. This gives students insight into the engineering problems Union Pacific faces. Solve one or more in whole or in part using the parts supplied.

  • When systems exposed to the elements fail, it can be difficult to quickly determine if the device or a cable has failed. Moisture in a cable can cause it to fail. Determine if the cable has failed or if there is moisture in the cable.
  • Equipment is enclosed in remote huts. Monitor a small room for the presence of a person to prevent theft and provide information in the event a technician becomes incapacitated.
  • Horns on locomotives must meet certain regulations. From a specific distance within specific humidity, wind, and temperature parameters a horn must be loud enough. Verify the sound level as well as the humidity, wind, and temperature.
  • A variety of equipment configurations used requires custom cables. The pin-out of the cables must be verified. Automatically determine the layout of a cable.
  • Many different radios are used with different cable and antenna configurations. Verify radio equipment is transmitting the appropriate signal strength over the air and provide a measurement of signal strength.
  • Crews working around the track must be alerted when a train is coming. Detect a train and alert the crew.
  • Inventorying a large amount of equipment in a short amount of time is necessary when a locomotive enters a shop. Wirelessly track and verify an inventory of equipment.
Parts

We will give you an Arduino board (most likely Seeeduino) along with some sensors and interface components. The kits will be different based on your proposed solution. We will provide ~$60 in sensors from the incomplete list below. If you have more suggestions please email me with them.

  • Sharp IR sensors (sparkfun: GP2Y0A21YK $9.95 10-80cm, GP2Y0A02YK0F $15.95 15-150cm, GP2D120XJ00F $13.95 3-40cm)
  • 3 axis accelerometer on break out board $19.95 sparkfun (MMA7260Q, LIS302DL)
  • Ultrasonic range finder $27.95 from sparkfun (Maxbotix LV-EZ0 0-255 inches in 1 inch increments)
  • Thermistors $1-$2 Jameco
  • Humidity and Temperature Sensor $41.95 from sparkfun (SHT15 Sensirion)
  • RFID reader Innovations ID-12 $29.95 from sparkfun. RFID tags $1.95 each from sparkfun
  • Xbee module 1mw with wire antenna $21.95 from sparkfun
  • 315Mhz transmitter from sparkfun $3.95
  • 315Mhz receiver from sparkfun $4.95
  • microphone and op-amp ~$5
  • KC7783R PIR Detector Module $9.45 from electronics123.com
  • Photo Interrupter CNZ1120 $1.95 from sparkfun.com
Prizes

All participants will get tee-shirt (design contest specific, more to come on this). The top two will win a significant prize, current proposals are an Ipod touch or a development tool like this usb oscope/function generator. (http://www.poscope.com/product.php?pid=13). Once we get the 25 participants locked in we will be looking for feedback on which you would prefer.
