Project Post #6: Virtual Vermin

Virtual Vermin

Jeff Brandt

 

One Sentence: A flexible, full functioning computer mouse designed with 3D modeling in mind.

(I think this is dressed up a bit more than “a computer mouse in a glove”)

Weekly Accomplishments:

  • Reconfigured soft switch buttons to stretch the conductive fabric further down the fingers
  • Submitted 3D print to Makerspace to print circuit board cover
  • Deconstructed glove so that the soft switches can be integrated

Conductive Fabric // Quantity: 1 sq. ft. // ? // Supplies in classroom

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 // $2.14 // creating in Solidworks

 

Areas of Concern:

Right now, my biggest area of concern is trying to determine how to best insulate the conductive fabric/thread paths that extend from the finger tips to the palm. I have a vision of how to do it in my head but as I have never had to sew multiple layers of things before, I am not sure if there are any tips that could be of help. Marianne, if you are available to run through this process again with me for a short period of time on Monday that would be great.

As for the electronics component, Kevin, I think I decided against the integration of a microcontroller. My current plan may not be the ideal configuration for an actual go-to-market product however it will accomplish, if not exceed, the goals I had set at the beginning of the semester for a first iteration.

  • Planned out remaining prototype design construction
  • Built first rendition of prototype for Vis Hat
  • Looking into current visualization code

Fu:

  • Circuit assembly on breadboard, optimize and design final circuit on protoboard..
  • NPN transistor build in circuit.
  • Tuning the resistor for higher sensitivity.
  • Looking code for duty cycles.

Jay:

  • Proof of concept testing, breath test using diodes on head
  • Circuit assembly
  • Resistor adjustments for sensitivity of photodiode

Project Concerns:

At this point we are in the home stretch of the course with a good amount to do. We have it all planned out, which works with the schedule but at this point have two potential concerns. One is that things take longer than planned. We hope to finish the build and testing this coming week, which could mean we find out our data gathering isn’t where it needs to be. The following week we’ve left for data visualization, which encompasses the data analysis and cleanup portion of the project, the demo setup (figuring out a good way of displaying everything for the demo and presentation) and coding the actual visuals. This shouldn’t be too big of a task, we just need to make sure we’re on top of it and thinking ahead. We’re planning to meet more outside of class time and planning for things in the meantime beforehand.

Project Post #6: ROETE

Radio Outdoor Emergency Transmitter Electronic

Natalie Tack

One sentence that describes my project: A device that transmits location via radio when activated in an emergency.

Weekly Accomplishments:

I figured out how to parse the GPS coordinates, I hit a snag with the remove method in Arduino, if you use remove(0) I thought it would remove the first character at index 0 in a string. I was wrong, it removes everything in a string from the zero index onward. So I fixed that problem.

I also programmed the device to wait for 3 button clicks, then buzz twice, then wait 30 seconds (less than a minute for demo purposes), then if no user input, the broadcast starts after the 30 seconds.

I also got the patch this week and found a jacket with an inside pocket that might work better for putting the radio transmitter in.

Earlier in the week I had problems with the radio connections again, as the radio wasn’t being registered as connected to the Circuit Playground Express. Hopefully this next week I can solder the connections and they’ll work all the time.

Areas of Concern:

This week I’m going to integrate all of the technology with the visual aspect. Sewing the button together and  putting all the electronics into some sort of container so that everything fits together.

I think that I’ll need some help this week just figuring out how to organize everything together so that it is easy to disconnect from the jacket to take out.

Also, the patch is non-traditional, so there is no satin edging. I might need help with how to make the edges of the patch look neater (in the image 2 of the patches are cut close to the edge, the other patch is still connected to a larger piece of fabric).

Project Post #5: Scavenger Stuffs

Weekly Accomplishments:

Second stuffed animal has been started and details have been added.

The game now has a working “travel” feature, allowing users to venture out with their animas for a set period of time. The user is updated every [x] seconds, showing what their Anima is up to

The server (GameSparks) has been fully set up to hold the information for the game. Right now, everything is being tested on the provided test harness, but I’ve been able to confirm some of the features such as the “Add Anima” script are working as intended on the gameside.

The RFID tags can now be read. The wiring is a bit iffy, so its not consistent yet. I’ve switched over to setting up on the RaspberryPI 0W for testing as a result. After many attempts with the bluetooth/wifi connections, I believe the best way of handling passing information will be making a dummy controller of Unity to load onto the pi and run to update the database.

Images:

 

Additional Material List:

    1. Battery/USB Charger (still torn on which I’ll be using, but right now it isn’t a priority)
    2. MicroSD Card (this might add a bit to the expense of the plush
    3. Cost of Plastic for 3D printing the pendants (depends on whether I’m crushing the old pendant ot make the new one, or working around the original key fob. Again, I’ll make this call once I have a base product working).

Areas of Concern:

Biggest issues this week:

  • The RFID Read/Writer works, but the wiring causes it to be a bit iffy as to whether its going to work or not. Shouldn’t be an issue once soldered, but I’m hesitant to solder without having a working temp on the 0W
  • Passing information is a bit odd since I don’t have a proper SDK for the pi. The best way of adding Animas will be writing to a file the RFID data as is implemented now, and then having a dummy Unity file waiting for that change and using the Unity SDK to pass the info up. The dummy Unity file works, and the RFID part works, so now it’s just a matter of making sure a Linux Unity build is viable and works as intended
  • (Also WIFI will be needed for the Animas due to this change. Not a bit deal, but since there is no graphical interface, I’ll either have to scan and jump on the nearest network or SHH into the pi whenever setting one up)

Project Post #5: Wearable Circuits

Wearable Circuits

This week, I’ve been looking into rectennas and trying to see if I can power small LEDs from RF from common sources like Wifi routers or leakage from microwaves.

I think doing an incredibly intricate design with impedance matching, ect. might be too much work for the time I have. I’m thinking it will be easier and more practical to experimentally determine what kind of energy I can collect with a small rectifying circuit.

I’ve been inspired by these two examples:

https://ieeexplore-ieee-org.ezproxy.library.wisc.edu/document/8072590

https://ieeexplore-ieee-org.ezproxy.library.wisc.edu/stamp/stamp.jsp?tp=&arnumber=8072590

Project Post 5 for Circular Pleating

 

Circular Pleating

  • weekly accomplishments list what you accomplished for each team member

This Week I finished the dress pattern and uploaded it to an illustrator vector,  I laser printed test pieces on the laser cutter and realized that I will have to map the pattern with dots in order for the pieces to have more integrity. Now that I have the process figured out, the dress making should become a lot easier.

I have also started writing a paper/ presentation that I will be giving at UGS this upcoming friday. Seeing as my project is kind of toeing the line of what we consider to be technology, I would like to chat along those lines.

This upcoming week I hope to laser cut, and start assembling a full sized garment. I’m also wondering how many I should hope to hit to be successful in this course.

 

changes to your approach after presenting your work what changes have you made in your approach

I am making sure to draft the patterns that will be cut in the laser cutter with dots. I think this will make construction a lot easier
