![]() ![]() “ uses four stepper motors to control the x-axis, y-axis, the bobbin case and the threading. “The translates a vector file into G-code and subsequently into Arduino language which then moves the machine,” Yu-Ning explained in a recent Instructables post. Interested in learning more? You can check out OSBee here and the OSBee Arduino shield here.Ī Maker by the name of Yu-Ning Lin has designed an Arduino-powered quilting platform that combines the mechanics of a sewing machine with CNC technology. ![]() Indeed, the OSBee Arduino library offers at least one example of using the Arduino Ethernet shield with OSBee shield to create a web interface for sprinkler control. While the OSBee shield itself is not equipped with built-in wireless modules, Makers and devs can stack it with other Arduino shields, such as RF, WiFi, Ethernet shields, to provide web connectivity. “The other OpenSprinkler products, such as OpenSprinkler 2.1s, DIY 2.1u, OSPi 1.4, OSBo 1.0, are all designed for 24V AC sprinkler valves, which operate on 24V AC and require a power adapter / transformer.” So it’s very efficient and suitable for battery-operated controllers,” said Ray. These valves internally use a latching solenoid, which only draws power when you open or close the valve, and does not draw power if it remains in the same state. “The main difference is that OSBee is designed to work with battery-operated sprinkler Tvalves. So, how does the OpenSprinkler Bee (OSBee) differ from other OpenSprinkler products? Different from the classic OpenSprinkler, OSBee now comes with a water-proof enclosure, which means it can be left outdoors, such as in a garden, and will do its work diligently, like a Bee.”Īlthough the OSBee itself is still in the prototype stage, Ray recently debut the OSBee Arduino Shield (V 1.0), which is currently available for purchase. “Also, ‘Bee’ reminds me of the garden, and gardens need to be watered, so, there is the connection. It may very well have an XBee slot in the end, but the name was not intended to imply XBee,” Ray of explained in a blog post. It’s coincidence that it sounded more like XBee. “The name ‘Bee’ comes from the abbreviation Battery-Enabled Extension. Recently debuted by RaysHobby, the platform is powered by an ATmega328 microcontroller (MCU) paired with a nRF24L01 2.4G RF transceiver.Īdditional key components include two AA batteries (boosted to 3.3V), SMT buzzer, push-button, 16KB EEPROM, PWM-driven boost converter, H-bridge (to drive sprinkler solenoid), soil moisture sensor and a Serpac 121 enclosure with water-proof perimeter seal. ![]() The OpenSprinklerBee (OSBee) is an open-source Atmel-based sprinkler timer (prototype) designed to work with battery-operated valves. ![]()
