“It is important that we make things for each other.”
- Sir Jony Ive
I used to love making mix tapes for people.
Sure, now you can make and share a playlist. But you could also send a birthday email instead of a real card. It’s just not the same
A product design challenge
Prototype a modern, spiritual successor to the mix tape that is easy to share, intuitive to use, and most importantly, fun.
An obvious, boring solution.
A thumb drive can hold lots of songs, is easy to share and intuitive to use. It’s just not very fun. But it’s the only wide-spread, off-the-shelf media standard left. I’d have to work with it, so I bought and tried dozens of brands.

I chose this one.

Measure twice
Based on the specific thumb drive dimensions, I drafted a blueprint to figure out how much room it would take to fit 3 in a case, because cases are fun. Cassette tapes had cases.
It wasn’t easy.
The issue wasn’t finding the right case size, but the right slimness. I searched through makeup cases, pill boxes, sewing containers—all too thick, too bulky to smoothly slide into a pocket.
Bingo.
I finally found this slim watercolor travel palette. It’s made of tin, and I liked the idea of attaching small magnets to the back of the thumb drives. It was time for the first prototype …and the first lessons.
1
Even the strongest glue struggled to bond the small, shiny magnets to the polished aluminum thumb drive bodies.
Small areas of prep grinding
2
The thumb drives were too flush with the tin, and it felt clumsy pulling them away with only two fingers.
More grip space between surfaces

It still didn’t feel fun, but why? How could I solve a problem if I didn’t even know what the problem was?
Take a break, do some tests
