LED matrices are a popular mean of displaying text, graphics, and animated information at gas stations, convenient stores, and many other public places. Raj’s new project is about making a Bluetooth-enabled 8×64 LED matrix display, where you can send the text messages through a smartphone over a Bluetooth connection. He used Arduino as the main controller and an HC-06 Bluetooth adapter to receive data from the smartphone. He has shared all of his design files and Arduino firmware on his blog.

Banguino brings the most popular hobby and DIY development platform in the world into a single chip DTX module and offers full backwards compatibility with the most used worldwide Arduino board – the model ‘Uno’.

Bonus features include an on-board power supply to generate +5V and +3.3V to the user’s external circuit, a microSD connector and additional 10 configurable digital I/O ports. There are also two software controllable LEDs on board as well as a USB-to-UART bridge. Banguino provides a highly integrated solution for building simple or complex circuits and benefiting from the large variety of already existing Arduino-compatible code.

solarcontroller

One year ago, I began building my own solar system to provide power for my village house.Initially I made a LM317 based charge controller and an Energy meter for monitoring the system.Finally I made PWM charge controller.In April-2014 I posted my PWM solar charge controller designs on the web,it became very popular. Lots of people all over the world have built their own. So many students have made it for their college project by taking help from me.I got several mails every day from people with questions regarding hardware and software modification for different rated solar panel and battery. A very large percentage of the emails are regarding the modification of charge controller for a 12Volt solar system.

ArduinoMP3

by Jose Daniel Herrera @ arduino-cool.blogspot.com:

I present this new Arduino project: A full MP3 player based on Arduino.
As you can see in the photo, the idea was to build a standalone player, in the style of antique radios or ‘tapes’, in the age of Iphones ….
The player uses a small module based on the VS1002d chip (now discontinued, but who had a drawer). The module in question I bought at Futurlec . Currently you can get similar modules on ebay for a bit more than 10$, although the chip is the VS1003 o VS1053. You can also use a SparkFun MP3 shield, but significantly more expensive (this shield already includes an SD slot).
The three chips are quite compatible in terms of programming, and indeed almost all initialization the I have taken from the library to the SparkFun MP3 Shield ;-)

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!

The Raspberry Pi is much more powerful than an Arduino but it has a few limitations of its own. Its I/O is much more limited, it can’t use common Arduino shields, and it needs a regulated 5V power supply via its USB connection. All those limitations are solved with the PiLeven.

RWXBioFuge preview v1.0

by PieterVanBoheemen:

Centrifugation is a powerful method for isolation of compounds such as DNA, proteins, oil or membrane vesicles from a complex mixture. The RWXBioFuge was designed to bring this powerful tool into the hands of labtechnicans, scientists, hackers, makers, diybio-ers and those who cannot afford to procure A-label equipment in low-resource settings.

It may also be used as an educational project to teach some fundamental principles of physics, chemistry, biology and electronics hands-on. Apart from an assembly guide, this documentation also includes 7 instructions for demonstration experiments and science classes.

Ever wanted to visualize your brain activity in real-time? Move an object on a screen with your mind? EEG devices are fantastic fun and allow you to do such things!

This tutorial will show you how to make an illumino: an easy-to-use recreational EEG device hidden inside a comfortable beanie, that turns your brain activity into an array of colorful light. Colors and brightness are manually selectable and adjustable via a small discreet pushbutton switch. The custom Arduino software is accessible via a USB port, allowing you to easily change it as you wish. The hat also works fine without the lights, should you wish to use it only as an EEG device. I recommend using Processing to create beautiful real-time moving graphical visualizations of your brain activity (code included in tutorial).

Turn your toaster oven into your own solder reflow factory shop using the Reflow Master Shield!!!

The Reflow Master Shield from Paladin Enabling Technologies is an Arduino shield that turns your normal toaster oven into a reflow oven. A reflow oven is used in the production of electronics to change solder paste from a paste form to a liquid form and lastly to a solid form. This results in all your components being soldered for you in one run.

But let me share with you why I’ve created the Reflow Master Shield and why you would want one.

ArduinoMicroLink

by elektor.com:

If Arduino is your development platform of choice the tiny self-contained MicroLink board offers some interesting features. At just 50 x 32 mm it contains an ATmega328, an SIM800H quad band GSM module and on-board USB and battery charging capabilities. It has all the peripherals necessary to allow wireless remote control and monitoring and can use any standard 3.7 V LiPo battery for power which is charged when the USB port is connected. The charge state can be checked at any time from a remote location.
