Yeahhh so much laugh and tears. It’s a knowledgeable journey, and here’s the presentation. Ooorahh!
This week I finished the board design for the muscle sensor, after trying several layouts.
( old ones )
Here’s the fake final look.
And I use OtherMill to mill the board, because the Roland can’t do the curvy routes.
And here’s the result whoo!
And then when I was happily ready to solder the parts on, I found out that what I ordered for the 150K, and 80.6K resistors were way too small!! Their type are 0402 instead of 0603! What was I thinking?! So tiny omg *_*
After being down for a while, I ordered parts from DigiKey again and refueled my life with hope.
And, I also found out that I have surface mount 1N1418 diodes when I was examining my parts ( so many mistakes ooops ), so I changed the schematics again! Replacing the through hole diodes with the surface mount ones, creating curvy dimension, and a making a hole for hanging, possibly.
Fourth of MASK collection – Duet
It’s a remedy mask for two people who hesitate to talk to each other. Separated from outside world with the mask, users sit with legs crossed, face to face, and communicate with each other through smiles. It’s for the eager of communicating without seeing each other’s face yet still feeling the intimacy. In the virtual world, users are surrounded by huge monsters, who will help the remediation process.
Small scale paper testing (Thank Origami master Uttam for the help!)
Then use mylar sheet for the final material. Got an angel helper Gladys!
Test putting it on two people! Need to add paper in the bottom part to increase the distance between two users, allowing the space for sitting with legs crossed face to face comfortably
— CODING —
Debug forever and ever yeahhhhhhh.
For my final project in Circuit Design and Prototyping, I plan to make a customized muscle sensor (EMG) for my thesis MASK, and the idea is to use the data as a measurement of mask wearer’s nervousness, and try to cope with it with MASK (virtually and hopefully also physically).
This is the first attempt to breadboard the muscle sensor, based on the design of the one on Sparkfun and also the tutorials on instructables. Because I don’t have the component, e.g. instrumentation amp, specific resistors, there are a lot of hacky moves, and I need sticker patch electrodes, 9v batteries*2, and components to know if it’s working or not :/
<– originally thinking to hook up two power supplies, but because it requires one’s positive connecting to another’s negative, I think I should ask Eric first to see if it’s safe to do that instead of using two batteries
Getting excited :DDD Lots of work and to be continued!
Third of MASK collection – Puppet
It’s a puppet mask that speaks for you when you are not in the mood of socializing but still wanting to be nice. It also helps you to escape the real world, and provides temporary healthy self-pity for you to enjoy
Use upholstery foam as paper. Trace the pattern on the foam and cut it.
Glue them with hot glue! Perfect match with foam. Thanks for the tips from awesome Jingwen!
So many hot glue sticks to make a head.
Body without hands and legs yet.
Waiting for elastic band to assemble all together! (Look like a creepy baby)
Second of MASK collection – Hive
It’s a community nest that connect people to overcome the distance. During the day, you walk and work as a worker bee. During the night, you come back to the nest and share what you got
