Connect the Magic – Challenge with Wiznet

Connect the Magic

Connect the Magic

This challenge is straightforward. Implement WIZnet’s WIZ550io Ethernet module, or W5500 chip, in an innovative design, document your project, and submit your entry.


The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI (Serial Peripheral Interface). W5500 suits users in need of stable internet connectivity best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY.

We also use W5500 in our product design. A new version of Seeeduino Ethernet you will see.

For more Wiznet enabled product, you can find them in our Bazaar.

If you wanna join the challenge, it  launches on March 3, 2014 and commences on August 3, 2014.

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:


nylon tape + Magic Tape


silicon tape + PVC + buckle


chainable plastic cases


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


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.

Electronics can be fashionable

Technology is no longer just the “design” feature, fashion designers started to collaborate with technologists because they want to make garments and accessories people will want to wear and include in their daily life.

Let wearable devices be trendsetters and people will love wearing them!

Imagine a world where your clothes regulate your body temperature, monitor your vital signs, and your necklace begins to glow when the sun goes down.


MAKE FASHION is an annual wearable technology fashion show. It introduced Calgary designers to the exciting world of wearables through a series of informative, hands-on, designer-lead workshops.

As the sponsor of MAKE FASHION 2014, we provided Seeeduino & Xadow series, which are extremely suit for designers and wearable applications.


Dr. Patricia Flanagan made Blinklifier with Seeeduino.

The Blinklifier explore the power of feedback loops in environments where human and wearable computers are intertwined and explores their application as tools for self-modification and sustainable change.

Make it wearable with Xadow


Tech Tie used the Xadow mainboard and 16 of the Xadow OLED screens – it was encased in milled aluminum and showcased a variety of scrolling designs.

We are glad to see them again at Maker Faire Shenzhen 2014!

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.

Hey dear you, are you in Shenzhen now? Or maybe you are on the way to Shenzhen :D

If you couldn’t see the above video, try this link

Why coming to Shenzhen?There are so many reasons. And the reason for coming to Shenzhen in April is Maker Faire Shenzhen!
Venue of Maker Faire (9)A little bird has just told us that representatives from Make Magazine, Sparkfun, 3Drobotics, the Institute for the Future and many other prestigious makers will be gathering here in Shenzhen.

What are you waiting for? Just come & join the big party!

Have fun!

Hi, this is sonic, the boy who is always dreaming.

Thanks everyone for joining seeed community since 2008, we couldn’t reach today’s achievement without our maker community.

Here comes the first comment on our blog is on the post: An idea about open source PCBs.

first comment ever

The Seeed Blog is proudly powered by WordPress, we share the same idea with wordpress to make thing done better and faster. Grove is the universal 4-pin interface, we want to make you start your project in 5 minutes, so this is the beginning.

This is beta version blog style, we like to hear your suggestion.
