The Proposal:
How can we implement NFC weight detection as a core feature behind a consumer product?
First Prototypes
Best grip textures, size requirements, PCB layout, power requirement, sensor implementation.
Expedited Testing
Let's fail fast and see what problems we initially encounter.
Key Learnings
1. Harness needs to increase in strength
2. Tags are reading inconsistently
3. Knob is seldom used
& other durability issues
4. Gym ownership requires magnetic charging
5. Edges of the device are being hit by weights
Hound in the World
A strength training gym used Hound for months and we regularly went over for feedback. By the end of three months, Hound was at 3 gyms in Columbus. 
Active vs. Passive Data
Some data ended up being more useful in the moment, and some data was better in hindsight. We split the two into "history" and "live view"
Intelligent Interpretation
"Genpop"wanted to be told what their data meant. We were able to identify basic patterns and label it for ease of understanding.
Mental Model
Recording status was not clear. Although we spent time and effort on the "always on" feature, people wanted to turn it on and off from the app.
Device Design V2
As we worked through more engineering issues with Hound, we pivoted to a smaller, flatter form factor without a screen.
