For a long time, OpenSprinkler Pi (OSPi) has been using the OpenSprinkler injection molded enclosure. While this has worked fine, the enclosure is not particularly designed for OSPi, leaving some cutouts not aligned with Raspberry Pi. Recently I have started learning to design enclosures using laser cut acrylic pieces. This is a great way to […]

Hey, it’s March already, that means spring will be here soon! Amid an unusually cold winter and freezing weather this winter in New England, we’re finally starting to see some warm winter days. No more snow please, we’ve had enough 🙂 Ars Technica This post is to give you some recent updates on OpenSprinkler and […]
Back in early December last year, we introduced a new feature in OpenSprinkler Firmware 2.1.1 that allows OpenSprinkler to directly talk to remote power sockets. With this feature, you can use OpenSprinkler to not only switch sprinkler valves, but also switch powerline devices such as light, pump, heater, fan. While it’s a powerful feature, it […]
In the past I’ve written several blog posts about how to use Arduino to interface with remote power sockets. For home automation involving powerline devices (e.g. lights, heaters, pumps, fans), this is my favorite solution, because it’s low-cost (remote power sockets are widely available at cheap price) and convenient (no messing around with relays and […]
As you’ve probably heard: the Raspberry Pi Foundation recently released RPi A+, which is the first RPi that’s smaller in size than any other RPi. It is essentially a B+ with less memory (256 MB vs. 512 MB), one USB port (instead of four), and a compact form factor (65mm vs. 85mm). Not only is […]
