Martin’s DIY Internet connected smart humidifier project:
The project uses a DHT22 temperature sensor mounted to the side of the enclosure for better ventilation and reliable reading:
I threw in a ultra-cheap I2C OLED status display to get a visual reading. Milling the box so that the OLED shows was pretty nasty, hated it. I cut a piece of paper and placed it on top of the cover, below the transparent lid to cover up for the lousy milling job
The humidistat switches on and off the humidifier as needed, the humidifier itself is plugged in to a plug in the relay. The auto detects when water is out and stops, so I didn’t have to care about that.

Even your device can be more user friendly thanks to various pictograms displayed on Winstar WEG series displays with a great contrast and viewing angle.
100×16 pixels at series Winstar WEG010016 isn´t that much at the first sight. But when we realize, that such display represents a sort of a “replacement” or “upgrade” of a character display (2×16-20 chars.), we´ll find, that it has wide possibilities of usage and it´s able to display much more than a character one.
Naturally, even a character display is able to display pictograms, but they´re limited by a given row or a matrix creating a given character. On the other hand, at a graphic display the whole area is available and naturally – it´s still able to display characters too.
Similarly like WEH series character displays, even the WEG series supports 4/8-bit interface „6800“/“8080“ and they have a built-in universal controller WS0010.
When we add advantages of OLED displays and attractive price, we have in hands interesting, universally usable display.

The MicroGame is an experiment of making a custom portable platform for gamming compatible with Arduino. It’s based on a small monochrome 128×64 pixels OLED from Adafruit and a ATmega32U4 8-bits microcontroller running at 8MHz. All hardware design and game source code is writed from scratch by me and you can find all the files in my Github repository if you want to build your own. You can modify, share and make improvements as you like but do not forget to shoot me and email and show me your work!

I take a look at the YZXstudio USB 3.0 Power Monitor with OLED display which is sold by Franky – http://stores.ebay.com/99centhobbies
I demonstrate this very handy tool on a UBS power bank and show the issues with the USB voltage and losses across a USB cable.

The Pixelduino is a tiny Arduino-compatible microcontroller with a full color 1.5″ OLED display + MicroSD built-in!
The Pixelduino is an Arduino-compatible microcontroller that features a 1.5″ 128×128 pixel color OLED screen and a MicroSD slot!
There are all sorts of things you can do with a device like this. You can create wearables like a watch, bracelet, pendant, or buckle that displays color images, attach sensors and display data in text or visual form, display debug information, create a graphics user interface, or even make simple retro games.

This is an OLED clock I built using an Arduino Micro, a tiny OLED 128×64 display using the SSD1306 controller and I2C interface, and a precision DS3231-based real-time clock module with rechargeable battery backup. It features a menu system for setting the RTC (no serial port or USB required)

While TFTs have been the mainstay of displays for years, OLEDs are becoming more prevalent as their price drops due to the phenomenal increase in quality from TFT to OLED technology. We received this demo board from Newhaven that effectively illustrates side by side the differences between TFT and OLED technology, using a 1.69 inch 160 x 128 OLED display and a 1.8 inch 160 by 128 TFT display.

RaysHobby build a project called RFToy:
it’s an Arduino-compatible microcontroller board for interfacing with radio frequency (RF) modules, such as the popular 433/315MHz transmitter/receiver, and the nRF24L01 transceiver. The RFToy has a built-in ATmega328, USB-serial converter (CH340G), 128×64 OLED display, three buttons, and a coin battery holder. Programming is done in Arduino through the on-board mini-USB port. It has three sets of pin headers to directly fit RF modules, and an audio jack to output RF receiver signals to a computer’s sound card. Using RFToy you can build a variety of projects involving RF modules, such as remote control and wireless sensors.

TinyScreen is a tiny customizable display. Play games, get notifications from your phone and display useful information.
TinyScreen is the new way to visualize your environment. With a beautiful color OLED display, TinyScreen is designed to be used to display information from the TinyDuino platform, which stack together like little electronic Lego’s.
With TinyScreen there are several default apps that will work right out of the box – like a Smart Watch app, a Video player app and a video game app. You can use these default apps with NO PROGRAMMING AT ALL!

I built a custom OBD II gauge in the clock of my Subaru BRZ (GT86, FRS) and a lot of people wanted me to build them one. Here is how you can build one of your own. My wife is about to give birth to our second son and all the code is open source, so I have nothing to lose by posting this.
