What project are you working on this summer? A low-power game module run by the EFM32 microcontroller? A touchless optical switch using the Si114x sensor? Or a Rube Goldberg machine connected via the EM357 ZigBee chip?
Whatever it is, share your cool project with your fellow engineers here by posting a photo of your project using a Silicon Labs' part and a short description of what it is in the comments below. We’ll pick three best photos based on most kudos (50%) and a voting system by our in-house judges (50%). The winners will receive a free PEAK™ (Matte Black / Black, $199.99).
In order to be eligible, your entry must meet the following requirements:

Hi, @antti you can post an image in the comment.
Software Defined Radio for the Ham bands, using Silicon Labs Si570 and PSoC.

I assembled a mini weather station with wireless temperature and humidity sensor. The receiver chip is Si4362 and the display shows alternating outside temperature/humidity along with the transmitter battery status and atmospheric pressure in mmHg units. The scrolling pressure graph is updated every 15 minutes and holds pressure history for the last 25 hours. The receiver is powered from a wall adapter, but has a rechargeable battery on board. Average current consumption is about 0.7mA in standby (because of LCD) and around 13 mA when receives data from the transmitter.
The transmitter unit uses Si7021 sensor and is build around Si4060. It is mounted outside in a PVC pipe, transmits temperature/humidity data every minute on 916 MHz band, and serves a similar receiving device as above at our neighbors. It is powered from XENO lithium battery and enclosed into a box from Radioshack. Average current consumption is about 10 uA. Previously constructed system based on CC1101 transmitters survived 2 last brutal Wisconsin winters and runs from such battery already for over 2 years.
I haven't started a project yet but I have got the samples
Maybe I can have a chance to win, who knows
reading the datasheet of #Si1102, this is the biggest step of a project
I'm currently working on a indoor unit for my weather station mesh network.
Weather Station project:
There is one weather station located in my garden, which broadcasts the data to all participants of a ZigBee network. The coordinator of the network operates as base station and passes the data on to a web-server, which displays the data in a chart. However if I want to know something about the weather data, I need a smartphone or a PC. So I decided to build a so called "indoor unit". These devices will consist of a TINY GECKO MCU, a XBee S2 radio, a 7-segment LCD (similar to the one on the TG STK) and a coin cell battery. The ZigBee radio will operate in a cyclic sleep mode and therefore join the mesh network as an end-device. It will wake up every ten minutes and check if the coordinator has new data available. If there is new data, the MCU will be woken up due to a LEUART interrupt and update the display.
Some improvements for the future would be a temp/humidity sensor for each "indoor unit" and a energy harvesting system to power it from indoor light.
I'm currently working on a project to make a scrolling display controlled by Zero Gecko Starter Kit. The scrolling display is used to give status update of a test. The scrolling display is used to display date, time and temperature (see video in the attachment).
Today is 21 August, who is the winner
