Project Post 5: Lit Lehenga

Individual: Jessica Fernandes

Weekly accomplishments:

  • I tested and wrote the code for the light sensor on the Circuit to turn on its lights in darker surroundings. The lights brighten in proportion to the environment’s level of darkness.
  • Materials I have: Circuit Playground Express, light sensors, power source to test
  • Materials on the way: LEDs, Enclosure, power source for final stage
I worked out the code to trigger the lights on the circuit playground express to illuminate in a darker environment.

Linked below are my pictures of:

Materials

Areas of concern

  • Ensure that the additional LED sequins are triggered by the light sensor; it doesn’t function as planned currently. Connect the hardware in a wearable configuration to plan where they’ll ultimately be sewn. (The materials are expected to arrive this Monday, April 8th.)

Project Post #5

Safe Sleeve

Jake Cordover

Weekly Accomplishments:

I have finally received the two sensors this week, thus I have begun implementing the program to measure the actual knee data. Bluetooth seems to be a little finicky, so I have focused on developing the code on a wired basis at this point. I have gotten it to the point where the accuracy seems to be within 5-10 degrees of the desired value, however, there seems to be a lot of noise and/or drift. I plan on hopefully implementing some techniques or researching what can be done to reduce the drift or noise.

Otherwise, I have printed a prototype of the enclosure that I will be using to secure the sensors. Since I have the sensors, I can adjust the prototype’s dimensions and design, and hopefully have the enclosure pretty close to the final version.

Images:

The images are of the 3D printed enclosure prototype.

3D printing and associated costs TBD TBD TBD

Areas of concern:

I’m a little concerned about the reliability and functionality of the Bluetooth, but at this point I am focusing on getting the best measurements using a wired approach.

Otherwise, the drift/noise issue is potentially very problematic. This may require a significant effort to smooth, otherwise I might need to start looking for a workaround.

Conductive Thread // Quantity: 2 yds. // ? // Supplies in classroom

Negative Poisson Ratio Foam // Quantity: 1 sq. ft. // Free // Supplied by my research lab

Gloves // Quantity: 1 // $11.95 // https://www.amazon.com/Agloves-screen-gloves-texting-gloves/dp/B004A9FI2M/ref=sr_1_6?keywords=thin+glove&qid=1552266834&s=electronics&sr=1-6

3D printed cover for circuit board // Quantity: 1 // ? (Depends on final print) // creating in Solidworks

 

Areas of Concern:

The same as last week but my plan is to complete all parts before integrating them all at once.

After prototyping the connections to circuit board, the area I am most concerned with is actually integrating all components into the physical glove. It isn’t a major concern and will most likely just take some trial and error.

  • Black velcro fabric (we have in the studio)
  • A Jacket (1, TBD)
  • (Safe) Infrared LED (20)
  • Long USB cable (x2) (for emergency and design)

 

Areas of Concern

  • Raspberry Pi Power Supply and Performance: We have a big headache. These are the approaches we tried to do — we might need some help
    • Change a PI — it’s on its way from Amazon.
    • Check Power Supply. — we tried to use Michael’s power adaptor (official), Mike’s  power adaptor (5V 2.4A), Mike’s roommate’s power adaptor (5V 2.5A and 9V 4A). None of them work. Our speculation is: the PI works, but the kernel might not be able to boot because of reason other than power adaptor (see below).
    • Check SD card image. — we tried the combination of the following methods — it does not work by far.
      • Change image (all newest from the official download website: https://www.raspberrypi.org/downloads/)
        • Noobs
        • Raspbien
        • Snappy Ubuntu kernel
        • Ubuntu Mate kernel
      • Change SD card format
        • FAT32: especially for TF card larger than 32G (https://www.sdcard.org/developers/overview/capacity/)
        • exFAT
      • Change TF card
        • Sony Micro TF 128G (Mike’s card — might be too large, but was bootable when using FAT32)
        • Samsum TF 32G
  • User Experience: How to let our users know how to operate without a screen?

Project Post #5: ROETE

Radio Outdoor Emergency Transmitter Electronic

Natalie Tack

Weekly Accomplishments:

This week I got the GPS working, the vibrator working (with Kevin’s help), and ordered the patch from the embroidery shop (thank you Marianne for the fabric!).

I also soldered all the connections for each respective module. The only thing that is not yet soldered is all the connections to the Circuit Playground Express. I want to get all the modules working together on the Circuit Playground Express before soldering those connections.

Areas of Concern:

I do not currently have any areas of concern for this week, I just want to get all the modules working together, so when the button is pressed three times, it should start the radio, then vibrate 3 times, then say the message on the radio, with the GPS coordinates.

I plan to get all the modules working together this week and then solder them together when they do.

Project Post #5

PROJECT POST #4

Project Title: Vis Hat  

Project Team: Lydia, Fu, Jay

Weekly Accomplishments:

Lydia:

  • Researched: visualization software and data transferring methods; existing data visualization; 3D printing materials
  • Visited maker-space and discussed 3D printing material specifications and properties to find best suited material for our project (we will be using elastic resin 3D printing material for the base and hard pva for the cover
  • Further drafted construction of 3D printed components and design of VisHat overall
  • Continued compiling experiment/testing procedures for data collection in response to different stimulus

Fu:

  • Finishing emitter and photodiode circuit connected to Arduino Due.
  • Test and complete Arduino Due analog read and pin out control.

Jay:

  • Completed emitter detector circuit and tested on head
  • Diagramed finished circuit
  • Fine tuning relating to current going to emitters, and sensitivity of the photodiode

Images:

Image 1 is a photo of the circuit setup connected to the Arduino Due

Image 2 is a diagram of the VisHat headpiece construction

Material List:

title/link # needed price/unit notes shipping and tax TOTAL PRICE:
arduino due 1 34.43 34.43
NPN transistor 1 5.99 this one unit contains ~200 resistors 5.99
730nm emitter 2 8.61 9.54 26.76
850nm emitter 2 1.46 2.92
850 max nir detector/sensor 2 5.37 9.02 19.76
bluetooth 1 28.95 RN41XVC (with chip antenna) 8.81 37.76
850nm emitter 2 1.46 To account for trial and error hardware testing 7.99 9.45

Project Concerns:

Now that we’re getting to the point of proof of concept a concern we may face might be noise within the data. We’ve been able to get response from the detectors that seems consistent with actions but whether or not the data collected when the emitters and detectors are placed on the head is from actual refraction or just from external stimulus may be hard to detect. Hopefully when we get to the testing stage we’ll know more about the state of the data.

Additionally, the 3D printing material we’ll be using is clear/transparent and that, too, may affect the kind of data gathered. The material can be painted so this could be a good plan to reduce additional noise.

Finally, we’re coming up on the mounting stage where the soon-to-be 3D components are attached/positioned on a user’s head. Everyone’s head shape is slightly different, so finding a way to make these as universally-fitting as possible while still maintaining structural integrity to the degree we need for the channels to remain stable enough may be difficult. The plan for now is to print a version 1 of the model, test it and its fit, and see if additional material integration like firm foam or memory foam to fit the hardware more securely to someone’s head might be needed for this to work best.
