We have received quite many great ideas for this campaign, but sadly we had to narrow down to 2 winners:

Luke Munn, an artist and researcher at CoLab in New Zealand.

” I have been researching wearable technologies for an upcoming work I’d like to produce, called “Net Time”. It is a wearable allowing for a bodily sensation of ‘internet time’ by polling server data, vibrating the skin/bone when each pulse arrives.”

Vignesh Ravi, an 18-year-old engineer from India, wants to make an open source medical grade multi parameter watch Prometheus (cool name!).

“Coming from a developing country I understand how technology has inadvertantly made lives better and how better can be scaled down to yield better results. I believe in future this data would be priceless and can enable predictive diagnosis.”

Congratulations to Luke and Vignesh! We’ll send you the Xadow modules required soon!

Xadow inspires ideas and fuels innovation in different fields. Let’s take a glimpse at Make Fashion 2014: 2 cool projects using Xadow that we wanna share with you!

Wearable design: Wristband

Xadow is designed for wearable electronics, and a typical application is wristband. My first understanding is that as wearable electronics, Xadow has special requirements for its enclosure: 1st, flexible & bendable as a band; 2nd, prevent damage of pulling force; 3rd, convenient to change PCB and for wearing. To solve the problem of bending, we try fastening PCB onto a soft belt. To avoid PCB & FFC from the damage of pulling force, the material of soft belt need to have a very high elasticity.

The following 4 sketches show the thoughts:

IMG_7456

nylon tape + Magic Tape

IMG_7454

silicon tape + PVC + buckle

IMG_7457-001

chainable plastic cases

IMG_7457

Nylon tape + clips

The soft band in the sketch above is nylon tape. There are magic tapes on the nylon tape and at the back of PCB. Use magic tape and the lower nylon tape to fasten PCB, and use clips to fasten the upper and lower tapes. On the one hand, the simple structure makes it easy to change and assemble PCB; on the other hand, the materials are very common in daily life, and the process is not complicated either. However, the downside is that the upper tape and lower tape couldn’t be synched in bending. Besides, different sizes of PCB make the appearance unsmooth, lack of esthetics. In order to synch the upper and lower bands in bending, we use screws to fasten the bands.

Sketch: Nylon Tape + Screws

untitled.90

Effect drawing- Nylon tape + screws

The pictures above use nylon tapes and screws to fasten the upper & lower tape as well as PCB. However, it still couldn’t synch the upper and lower band in bending. Besides, the large number of screws makes it quite messy. That’s why we stop going in this direction.

These pieces here also used the Xadow components

We had fans that lit up when moved with the accelerometers, and lights programmed by the Xadow mainboard, and the umbrella would create patterns with the LED’s when they were spun.

Xadow is a though small but perfectly formed Arduino(TM) compatible board series containing several modules. It’s a kit extremely suitable for space-sensitive projects such as wearable devices & arts designs, which have higher request on size, weight and flexible cascade connection. You can find more modules here.
