What we’ve been doing the last few weeks…
Once we found out Digits would be going to production, we took a second look at the product, for usability and manufacturability.
With the original design, our manufacturing partners were not confident that a safety pin the size of Digits would be strong or usable. For this reason we started to investigate changing the method of attachment. We still wanted it to pierce through the glove, so it would not fall off, so we revised the design to be more like a push pin. The final concept that the factory approved will be a push pin style pin that you push through the glove with your finger. The sharp point gets pushed to the outside where it snaps into the front part of the digit.


The other piece of the puzzle that has shifted is the materials involved. When Digits went into presale, the part that contacted the touchscreen was made of conductive thread. All of the touchscreen gloves out there used this material, and we made some prototypes in the shop with the threads and they really worked, so we were excited about it. Once we went into manufacturing, the factory had a new material they suggested to us: conductive silicone. The silicone was even better since water rolls right off it, which we thought might be helpful in the snow. To make sure the silicone worked as well as the threads, we got a sample from the factory, left it in the freezer for half the day and then tested it on our touchscreens. We found it to be just as good, if not better.
After we confirmed the new materials, our partners abroad sent us the details on how the factory would proceed. The metal parts would be made on a lathe, which is a machine that catches the material on its ends and spins it on its axis while you carve away. This is perfect for a part that is small and round, and perfect for us because we wouldn’t have to pay for new tooling, just the labor of creating the part. The factory would then take the metal part for the outside piece and overmold the conductive silicone onto it.
What we’ll be doing over the next several weeks…
While Nikki (our amazing Ops specialist) was in China last week, she got to see the first factory prototypes of Digits. (image below: only part of the surface was covered with the conductive silicone, so we could see the material behind)


She sent us this email on November 15:
Hey All,
So I tried the Digits this a.m. and I’m really impressed. This product, when it’s correct, will be awesome.
It’s not bulky at all and the function works. In fact, it’s so not bulky, that I could still text using my Blackberry keypad.
They are fully aware of all the changes that need to be made to these. We’ll see the T1 by Nov 24.
The T1‘s will have corrections already made from the protoypes Nikki tried, so hopefully there will not be much more to correct (or nothing at all!). Because of the holiday, we should be seeing T1 samples early next week.
