Martin Harizanov’s WiFi-enabled thermostat runs entirely off the ESP8266 SoC and is controlled through a touch-friendly user interface running on mobile devices. His project also has broadcasting functionality, which allows the thermostat to send data to thingspeak.com or similar platforms.

If you have any spare old phones with no use lying around, you may want to use their batteries to build this portable charger for your new smartphone. On the electronics side, this project only requires a LiPo battery charger module and a step-up voltage converter module, both of which can be bought for less than $5 on eBay.

Rui Santos has written a short tutorial about creating a standalone web server using an ESP8266 module that can toggle two LEDs through a web interface. He first flashed the ESP-01 module with NodeMCU so that he could program the ESP8266 chip with LUA script. After that it gets pretty easy to modify the ESP8266 firmware for WiFi connection, controlling the GPIOs, etc.

The ESP8266 Wifi-to-serial transceiver is the latest and most inexpensive way to get your project connected to the Internet. If you wonder how to setup up this thing in your project, this Start-Up PDF guide from rancidbacon.com will be very helpful to you.
Out of many ESP8266 modules available in the market, the ESP-01 version is the most popular one. While the headers are 0.1″ pitch, the pin arrangements are not breadboard friendly and are not labeled on board, which makes it little inconvenient for breadboarding. So you might be interested in our Breadboard Friendly Adapter (shown below) with clear pin labels printed on the board to make prototyping with the ESP-01 module easier.

Jesus Echavarria’s PICnano is a breadboard-friendly breakout board for the PIC18F2550 microcontroller in an Arduino Nano form factor.
The goal of this new design is try to have an Arduino Nano compatible module but with some new features, such have direct access to the power supply microcontroller. First of all, here you can download the schematic of the board: PICNANO BREADBOARD SCHEMATIC V1.0.
The board is based on the PIC18F2550 microcontroller, here you can download the datasheet.
