Around Thanksgiving last year, I received a request from a biology lab professor who commissioned me to modify OpenSprinkler to become a custom fluidics controller. The goal is to achieve web-based, programmable control of fluid selector valves, linear actuators, relays, and air valve, to automate a custom biology experiment. I don’t typically accept contract work, […]

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 […]

When I first had the idea to design OpenSprinkler Pi (OSPi), a secret motivation was that one day I figured out how to fit Raspberry Pi into the existing OpenSprinkler enclosure. Yes, it sounds silly, and you can laugh at it; but if you understand how much it costs to make an injection molded enclosure, […]

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 […]
