Jogo de 4 pastilhas de travão dianteiro para o seu VOLKSWAGEN GOLF II (19E, 1G1) 1.6 (70Cv) WATERING SYSTEM - INTRODUCTION. INTRODUCTION & OBJECTIVES: I is a simple system, using Arduino to automate the irrigation and watering of small potted plants or crops.

WATERING SYSTEM - INTRODUCTION

This system does the control of soil moisture, doing indications via LEDs and in case of dry soil emitting a alarm beep. In case of dry soil it will activate the irrigation system pumping water for watering plants. The system uses a LCD display to notify all actions that are taking place and a real time clock. The Theory (from Wikipedia): Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, fruit, or wood.

Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation.

SwarmControl

The SwarmControl project aims to understand the best ways to control a swarm of robots by a human. The project achieves this through a community of game-developed experts. The project is continuously changed to promote the creation of experts and to become the most effective exploration tool. To achieve this, the project gathers and analyzes data.

Frameless Geodesic Dome

It’s a frameless geodesic dome designed to be easy to fabricate and build. It is 18 feet wide at the widest point and about 13 feet tall. It feels very spacious for it’s 209 square foot floor. The dome shell is built out of 3/16” corrugated plastic and 3/4” blueboard foam insulation. The shell of the dome is a basically a foam board insulation sandwich. Arduino-Based Curtain Automation, 006. Anatomy of a cheap USB to Ethernet adapter. Taking apart a very cheap USB to Ethernet adapter and pondering on the parts found inside.

Anatomy of a cheap USB to Ethernet adapter

Here are two USB to Ethernet adapters: One of them is sold on ebay for $3.85 AU ($3.99 US), including postage to Australia. The other is sold at Apple Stores for $29. In Linux they both use the driver for an “ASIX AX88772A” USB to Ethernet converter, even though the Apple one reports as “Apple” and is sold only for the MacBook Air. The cheap adapter comes with drivers for OS X & Windows, as well. DIY 360 Degree SODAR Device. First off, why did we decide to call this thing SODAR?

DIY 360 Degree SODAR Device

SOnic Detection and Ranging, or SODAR, is a lot like SONAR and RADAR. However, we don't feel comfortable calling it SONAR because we have no desire to use it for navigation and we aren't under water. Also, it's definitely not RADAR as we are using ultrasonic pulses, not radio waves to find objects. Strandbot - a solar & arduino powered R/C motorized Strandbeest.

Intelligent watering system with arduino...

Humidity sensor takes constant readings of the soil moisture and transfers to Arduino which controls a mini servo attached to a tiny valve. you can tell the system amount of moisture needed simply turning the potentiometer... then the system opens and closes the water valve if the soil is below your specified level of moisture... Fabric Formed Tea Table in GFRC. Teen tech camp recap. As some of you may already know, last week I had the honor and privilege to help organize the 2013 Teen Tech Camp in Durham, North Carolina.

teen tech camp recap

The event was extremely challenging, fun and one of the most rewarding things I have ever been a part of. the idea The idea for the camp came from my experience at the Teen Tech Camp in 2012. Refresh the Triangle, a community made up of area designers and developers, hosted the camp and focused it around web applications, websites and web design.

The kids learned about HTML, CSS, web design and other web-related technologies from local professional technologists. 507 Mechanical Movements. David A. Mellis: DIY Cellphone.
