A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
It’s time to launch your personal epoch.
Time Since Launch is a single-use, long-scale launch clock. Pull the pin to begin counting for 2,738 years.
Use this very long-scale timepiece to mark the beginning of your epoch. It could begin when you get married, have a baby, quit smoking, launch a rocket, or on an ordinary Tuesday morning.
Your epoch is safeguarded within this unique timepiece designed and over-engineered to outlive you. Suspended in a durable borosilicate glass tube and sealed with gasketed aluminum end-caps, two LCDs show days, hours, minutes and seconds since launch. This timepiece is built to count for 2,738 years.
Elevate an otherwise arbitrary moment to super awesome status.
Inspiration. 1962. MA-6. John Glenn. A stopwatch. A shared global timezone.
When John Glenn became the first American astronaut to orbit earth, the only piece of technology on his body, other than a spacesuit, was a 12-hour stopwatch. Soon after launch, Glenn started his stopwatch in sync with tracking stations across the world. At that moment, Mission Elapsed Time (MET) began counting up from zero. A launch timer was not only required for a successful mission (ie. to calculate position), it also created a shared global timezone.
Quietly situated at the center of a tremendous collaborative feat of human innovation, the launch clock marks an arbitrary Moment Zero. A moment shared by humans scattered all over the world and one hurling through space.
What’s your Moment Zero?
You might pull the launch pin when you drop everything and join the peace corps, or when you stop drinking, or when you and your best friend move to different cities and want to maintain closeness through a shared timezone. It's also ok to launch on a random Wednesday morning, making that moment special, simply because you want to make it yours.
Make time your own.
We keep time, consume, and organize around it. Time rules us and we don’t own it.
Time Since Launch is as much (if not more) about presence, than it is a reference to the past. Beginning with a single moment, Time Since Launch is a continuous reference to our brief existence on a continuum far greater than we're used to imagining every day.
When you’re ready, pull the stainless-steel launch pin to initiate the timer. You can only do this once! This action begins a chain reaction burning that instant into the chip’s silicon, making it yours forever.
Time Since Launch does one very specific thing. It does that thing well. And it does that thing for a very very long time.
Technical description and design overview.
Building a 2,738 year timepiece. Time Since Launch is off the grid, both in terms of power and its ability to keep accurate time. Unlike your phone, it doesn’t rely on a surprisingly fragile external multi-billion dollar timing and power infrastructure.
Made with precision machined metals, over-engineered and over-specified electronics, Time Since Launch will outlive you. This assembly of parts - from physical materials to electronic components - were selected with longevity in mind.
Time Since Launch ships with its LCDs in pre-launch mode, this rhythmic cycling through each of the segments ensures even wear and tear.
On launch, Time Since Launch burns your moment into the chip's silicon and begins counting. The displays indicate elapsed time in your epoch, counting up to 999,999 days, 23 hours, 59 minutes and 59 seconds.
If anything ever happens to your Time Since Launch, as long as the chip is physically intact, you can recover your Moment Zero and transplant it into a surrogate.
Materials selected for durability and legibility. Time Since Launch is made from machined aluminum endcaps and a durable borosilicate (Pyrex) tube. The electronics are suspended and deliberately made visible. The enclosure is easy to take apart. If ever something breaks, you can easily identify what went wrong so it can be fixed.
Electronics specified for longevity and low power consumption. Time Since Launch consists of only essential electrical components to mitigate potential failure points. Mounted on a matte black PCB with gold plated traces, Time Since Launch has 2 chips, a few passive electronic components (resistors, diodes and capacitors), two 6-digit LCDs and batteries. That’s it.
It draws less than 6uA (microamps) of current running at 3.3 volts. This gives us an energy usage of about 20 microwatts (millionths of a watt).
A 20+ year battery life. Time Since Launch ships with 2 x AA Energizer L91 Ultimate Lithium batteries. These batteries have a capacity of 3,500mAh, and a 20 year shelf life, which means they are guaranteed to have 95% of their original capacity after 20 years of sitting on a shelf.
To arrive at our 20+ year battery life estimate, we take Energizer’s stated capacity of 3,500mAh and round down to 3,000mAh (to be conservative), divide by 6uA and then take off another 30% (to account for external factors). This gives us an estimated run time of 40 years.
A real time chip with ±2ppm accuracy. To keep time, Time Since Launch uses a DS3231 chip. This real-time clock chip with a temperature-compensated crystal oscillator is accurate to ±2 parts per million (ppm). This level of accuracy is 10x better than a normal wristwatch crystal which, with an accuracy of ±20ppm, can loose or gain up to 1.73 seconds per day.
If you were to shoot a basketball from a court in NYC to a hoop in Philly with ±2ppm accuracy, you’d miss by less than 10 inches.
Safely change batteries without losing time. About 6 months before it is time to change the batteries, the display indicates your batteries are low. During the swap, backup capacitors keep the real time chip powered and running without losing time.
To change the batteries, pull the aluminum caps out of the glass tube to expose the battery holders. Pull out your old batteries and put in new ones.

Thank you to Keira, Kristen, and Irene for letting us shoot in your beautiful homes! Thank you Claire for helping out with every random task we came up with. Thank you Bobrow for the continuous feedback since day one.
CW&T is the art and design practice of Che-Wei + Taylor.
We live in a world of our own making. It's a world where every object has its purpose, although not always purposeful, and where common objects receive uncommon consideration.
This is our 7th rodeo! We're committed to delivering the highest quality, most thoughtful work imaginable. We understand the risks of manufacturing. This project brings the challenge of a BOM that requires CNC machined components, custom glass, PCB fab, electronics sourcing, and more to all come together on time and be perfectly awesome.
We refuse to compromise quality. If at any point this means a project delay to make sure things are perfect, that's the way we go. Our priority is to make things properly.
When making anything new, there are always unknowns and points of failure. That said, we are accountable to our supporters and do everything in our power to cover our bases so everyone is happy.
We're looking forward to this adventure with you all, whether it's your first, second, third, fourth. fifth, sixth, or seventh! time working with us. :)
