 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.

minipsu1

by sebulli.com:

Very small power supply unit in the size of a cigarette box. The input voltage is 24V. Its supplied by a external switch mode AC/DC PSU. The output voltage range is 0V to 24V at 0A to 3A. A switch mode preregulator reduces the power loss. This allows a very compact design. Voltage and current are displayed on a RGB OLED display

Featuring 3 OLED screens on a flexible circuit board, this minimalist electronic wearable is stunningly bright, likes to be touched and features a rechargeable 10 hour battery. Apologies about the hairy arms (and the dubstep)!

This is just a prototype but with a just a little more work this could easily be thinner and more attractive to wear. Be on the look out for a new version with some 3d printed parts to present a more honest take on the bracelet.

princeton-led-efficiency-increase

by Colin Jeffrey @ gizmag.com:

With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to have come up with a way to change all that by using nanotechnology to increase the output of organic LEDs by 57 percent.

Viewing angle around 160°-170° and an excellent contrast say in favor of character displays with OLED technology.

OLED technology (Organic LED) slowly but surely finds its place even in industrial devices. After a big success at mobile phones, where they convince by high contrast and an excellent viewing angle, this technology becomes price-affordable and technologically advanced even for industrial applications.Benefits in short:

  • OLED means, that every pixel is principally one „planar“ LED, thus each pixel emits light (white, RGB or some color). That means, that OLED doesn´t have / doesn´t need backlight and it also helps to a high contrast, as there´s no problem with a light bleeding through “off” (black) pixels, as it is often at LCD displays. High contrast also ensures excellent legibility even at a strong daylight.
  • wide viewing angle. As every pixel (point) is itself a light source, it shines in all directions (half-globe) and it provides an extreme viewing angle near to a theoretical maximum of 180°
  • extremely wide operating temperatures range, frost doesn´t “slow down” display response time
  • the same color from every viewing angle. This is vital at color (RGB) OLED displays and it means almost zero color shift at viewing from various viewing angles, so well-known from TFT LCD displays
  • low power consumption, partially dependent on a display content (number of switched-on pixels and their intensity)

New character displays from company Winstar belong to advanced displays with declared features. In our stock can be found types for example WEH001602ABPP5N00000 (16×2, blue), WEH001602AWPP5N00000 (16×2, white), WEH002002ALPP5N00001 (20×2, yellow/orange – „amber“) and WEH002004ALPP5N00000 (20×4, yellow/orange – „amber“) and other. They all have 8-bit parallel interface „6800“ and a modern controller WS0010. Direct comparison of OLED display with an FSTN LCD is best illustrated in the attached video.

lg-display-oled

By Darren Quick @ gizmag.com:

After unveiling the world’s first flexible OLED TV at CES earlier this year, LG has gone a step further with the unveiling of two new 18-inch OLED panels: the first is a transparent display, while the second can be rolled up. Although both fall short of the 77-inch flexible TV on show at CES, the company says the new panels prove that it has the technology to bring rollable TVs with screens in excess of 50 inches to market in the future.

So it’s been a while since I last posted about my OLED watch, and I’ve done a lot of work on it! (And also broke it multiple times)

It’s taken me a lot of work to get this far, and I developed EVERYTHING from the ground up. The electronics design, the PCB layout, the RTOS and firmware drivers, the graphics engine, the user-mode app code, and even USB communications apps. I’ve used C, C#, and Python extensively in this project, and Altium Designer for the schematic and PCB.

Overall it has been an awesome learning experience, and if I was to make another one I would do a lot of things differently!

The WifiDuino is the chip-sized Arduino + Wi-Fi + 128×64 OLED at low price that is easy to use.

WifiDuino is an open-source Arduino-compatible, wifi-enabled board. It allows users to use Arduino IDE (Integrated Development Environment) interface to write programs directly, and with Wi-Fi function. WifiDuino is user friendly, get started in no time. What’s different from Arduino Wi-Fi shield is that WifiDuino is a lot smaller in size, cheaper and easier to use.

WifiDuino is an open source project, which means you are welcome to develop and improve the project if you want. It is also ideal for beginners too. WifiDuino and Arduino are used the same chip. You can quickly learn how to make things with WifiDuino with its rich library resources from the Arduino database.

OLED Watch v4.2 @ Walltech. John writes-

I just finished writing up my OLED Watch project on my website! I took loads of great pictures, and explained the whole thought process of the project, as well as the hard ware and software behind it! I’ve officially released the board files and the code under the appropriate creative commons licenses, and just wanted to let you know that it’s all now online on walltech.cc! You guys have been strong supporters of my projects and really thank you for that.
