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.

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.

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.

You are planning to use Arduino in your project but you need some kind of remote control functionality. A standalone Arduino won’t provide what you need but this DIY shield may be a good solution for you. It includes a 433.92Mhz RF receiver which lets you send commands to Arduino wirelessly and four SPDT relays which can be used for switching purposes.
Each relay is capable of switching up to 10A @ 250VAC so they can be used to control mains powered devices. There are four LEDS indicating the status of the relays. The terminal blocks on the shield lets you easily connect the devices you will control.
The RF receiver is a module that can be found in the market easily. It is directly soldered to the shield and runs at 4800bps. The board has an antenna input which lets you solder your custom antenna to increase the wireless range.

This article is a about a fully functional water level controller using Arduino. The circuit displays the level of water in the tank and switches the motor ON when the water level goes below a predetermined level. The circuit automatically switches the motor OFF when the tank is full. The water level and other important data are displayed on a 16×2 LCD display. The circuit also monitors the level of water in the sump tank (source tank). If the level in side the sump tank is low, the motor will not be switched ON and this protects the motor from dry running. A beep sound is generated when the level in the sump tank is low or if there is any fault with the sensors.

In a presentation at the Maker Faire held in Rome this weekend Arduino co-founder Massimo Banzi gave a preview of the soon to be released Gemma wearable Arduino board. The 27 mm diameter board contains an ATtiny85 processor programmable from the Arduino IDE via Gemma’s micro USB connector. The design is a collaborative effort together with Adafruit Industries who also worked on the Arduino Micro.
The ATtiny85 has 8K of flash and 5 I/O pins, including analog inputs and PWM outputs. It was designed with a USB bootloader so you can plug it into any computer and reprogram it over a USB port (it uses 2 of the 5 I/O pins, leaving you with 3). Ideal for small & simple projects sewn with conductive thread, the Arduino Gemma fits the needs of most of entry-level wearable creations including reading sensors and driving addressable LED pixels.
