I realize now that i had the wrong chip. the ATSAMW23G18-MD1. is the 802.11 module.
Digikey has the Dev board available on the 08/20 so untill then we are working with a SAMD21 MCU and a CC3000 Wifi Chip.
Looks like it is now 11/27! man they can't hit a ship date... atleast it's my birthday.
no, i'm not laying off my colaborator, just shrinking the chip.
since atmel can't get thier act together and get me the awesome wireless chip I may as well use an attiny with a usb bootloader. so switching to the Attiny 1634. still has i2C and SPI and 16k flash, Plus.... a internal thermometer! yay bonus! and the package it waaay smaller, 4x4. whoo.
The SAMW23 dev boards are delayed until 11/27/14 so i guess i will just design with the other wifi chip.
An alternative would be to grab a accelerometer with a MCU in it but I feel going away from the D21 architecture would be a mistake if eventually i want to use the new chip. So rev-01 will be a little larger than planned but should still work great for most applications. I'll get going on that board design.
At least the accelerometer is. and granted it's only 5 wires. but great none the less.
ooh, i didn't know i could upload photos... peachy.
And also a pretty bad phone video.

The CC3000 wifi breakout and the MMA8452Q Accelerometer break out are here. Yay. The accelerometer uses I2C and the CC3000 uses SPI. fun huh? i am excited when i get the all in one chip and can reduce the complexity. I am really liking the simplicity of the accelerometer. Very few pins are needed to power, talk to, and get interrupts. plus they all run off ~1.6-3.6Vdc
Nice low power. I just added Josh to the Github calaborators group. hopefully we will get some code brewing soon.
got my samd21 dev board up and running. now i need the sensors.
Digikey says the wifi dev board is supposed to be available on 8/20. here's hoping.
I Managed to get a colleague interested in helping with the programming so i can focus on board layout for the smaller version. its been 3+ years since I've done board layout so let's see how easy it is to jump into Ki-Cad.
His Name is Josh E. say Hi
So after my big mistake i am trying to find a good wifi and controller solutions. I still think i will plan on using a SAM D21 ARM Cortex-M0+ MCU controller but until the Soc package with integrated wifi comes i will just have to put the items together externally. but what is the closest thing to the wifi module they planned on having integrated in the ATSAMW23G18-MD2 (it just says atmel Wifi, which doesn't exist.? I'll order things today.

Sometimes Im so busy i forget to drink water only to realize it when my head hurts.
I thought of the exact same thing about a month ago. I was planning on using a PIC (obviously) and a accelerometer + a piezo buzzer. The PIC would run a timer based RTC and beep every 20 mins to remind me to drink.
No IoT on my project though.
Seing your project made me think just a pressure switch on the bottom of my thermos would do the trick, or another piezo that triggers when the water is placed back on the table.
Now i HAVE to build it.
