Next, also solder crystal X2 - it’s a 32.768kHz cylindrical crystal for the Real-Time Clock (RTC). After soldering, use a diagonal cutter to clip the excessive leads. Make sure your soldering iron is hot, and can easily melt and reflow solder.
This way you can solder multiple components at once. You can use as many pieces of tapes as you need.
To increase productivity, I usually insert multiple components, and use painter’s tape to fix them in place (see image on the left).
To solder, insert the components through the PCB holes. Crystals are non-polar, so it doesn’t matter which orientation you insert them. It’s important you don’t mix them up, otherwise the controller will not work. Check the images on the left to see where they are located. The two crystals have exactly the same shape, so you must read the label on the components to tell them apart. Start with crystals X0 (16MHz) and X1 (25MHz). Remember: all images on this page are ‘clickable’. (If possible, use a fume extractor to help remove solder fumes). To begin, place the PCB onto a a vise, and turn on the soldering iron. Nov/14), the reference images of the assembled board as below: Update: if you have received the Nov 14 Revision of DIY 2.2u (check the upper-left corner of the PCB and see if it says Rev.

Click the images to see them in full resolution. To give you a heads up, here are two high resolution images of the assembled board (front and back). They are available in many brands and a variety of places (Lowes, Home Depot, Amazon…). If you have an existing sprinkler system, you should have these parts already installed, and you can reuse your existing sprinkler transformer if not, you can purchase them online or at local retail stores. DO NOT throw away the plastic bag until you are done with soldering.Īdditionally, you need a sprinkler valve transformer (rated 24∼28V AC) and one or more sprinkler valves. Small components may get stuck in the plastic bag. Before soldering, carefully place the components in a box or container. Warning: electronic components are small and easy to lose. Cold soldering iron is a major source of soldering failure. The most important tool is a good and hot soldering iron: it should provide high temperature to melt and reflow solder. If you are new to soldering, please take a look at the Preparation page. OpenSprinkler v2.2u kit includes a semi-assembled circuit board, through-hole components, LCD, and plastic enclosure. You can control your device from outside the local network with proper port forwarding and use of the WAN IP within the application or by using a VPN.( Note: all images below are ‘clickable’, in order for you to see the full-resolution details. This application requires you to own an OpenSprinkler that is properly connected to your network. * Multiple supported languages (Afrikaans, Amharic, Chinese, Czech, Dutch, French, German, Hebrew, Hungarian, Italian, Mongolian, Norwegian, Polish, Portuguese, Slovak, Slovenian, Spanish, and more) * View current weather and forecast status for the device location * View graphical and tabulated representation of log data * View visual representation of upcoming scheduled programs * Launch ad-hoc or defined programs instantly
OpenSprinkler is an open-source Internet web-based sprinkler timer / controller built upon the Arduino platform. The application allows you to automatically detect and control your OpenSprinkler irrigation system(s).
