I just discovered a very nice connected e-ink display on Kickstarter : Displio.

It is simple, nice, fully customizable. I could set up a bunch of them at home, displaying various information… if it was a bit cheaper…
But still, very nice (and already funded) project !
I received my WiDos ! Three of them. They were out of stock so I had to wait a few more days after order but they eventually arrived through DHL delivery after one week of patience. I had to pay french taxes in addition the product price. Fair enough : I was warned !
The WiDo is an Arduino Leonardo compatible board including a Wifi chip and an SD card reader. It should be noted that some on the pins are used by either the wifi or the SD card : pins D4, D5, D7 and D10 are not available. Also, the wifi chip is using SPI top communicate with the microcontroller.
The Jorjin WG1300 seems to be based on the TI CC3000 chip. So it work with the Adafruit CC3000 library. There is also a WiDo fork for the library but it seems there is no change to the library itself. Only examples are updated (changing IRQ pin from 3 to 7) or created (Xively…)
I stuck to the the Adafruit original. I just loaded the buildtest example, changed IRQ pin, set my Wifi SID and WPA password… and it worked like a charm !
The only problem I have with one on the board is the mis-alignment of some headers.It is not preventing the board to work but you can’t use shields as they won’t fit. I may try to re-solder the header.
So, at around 25€, the WiDo is a great replacement for an Arduino + Wifi shield which costs around 70€ ! And it works just like the Adafruit CC3000 Wifi shield.
The next step is to port the Wifridge on WiDo.
By the way, official documentation is here.
After presenting WeIO, here is WiDo from DFRobot, yet another Open Source IoT node.

It is basically an Arduino Leonardo which includes a WG1300 WiFi chip. Apparently, this can be used with Adafruit’s CC3000 Arduino library which should make it quite straightforward to use.
What’s the difference between an Arduino + a CC3000 shield then ? The price ! At less that $30, it makes a quite cheap IoT plateform !
Ordered some… (DHL shipping is free until the end of september) but no more in stock. So I don’t know when I will receive them 🙁
Back in june, I went to the Maker Faire which took place in Paris.
I saw for the first time a new little but powerfull platform which was under development : the WeIO. It looked like quite promising.

Creators of this new “Web of Things platform” just launch a crowdfunding campain on INDIEGOGO. Their goal was to reach $10.000… After 2 days, they reached… $9.568 ! No more early bird offer but you can still support them and pre-order this new gizmo ! I just did !
Can’t wait to play with it…
Just a quick news because I just discovered a product that seems quite nice : the Electric Imp.
It is a typical Internet of Thinks gizmo which allows adding Wifi and internet connectivity in a quite simple way (it seems…) with a small foot print (and standard, like an SD card although it is NOT an SD card and it WON’T work as an SD card) at a quite low price.
It is easy to configure using a smartphone. The dedicated app is making the screen blink to send the configuration data to the Imp.
Just ordered it from Snootlab… can’t wait to test it !
