2/11/2023 0 Comments Opensprinkler power raspberry pi![]() I am experienced enough with Linux and the Raspberry Pi to take care of the software side of things with no hassle, but I just want to get the hardware purchase right first time. It’s the cheapest and most configurable system of its type I’ve come across, it’s open source (and this means that Ray’s not the only person working on it tools from the community like Rich Zimmerman’s SprinklersPi software add features like weather control, so you can adjust your irrigation depending on your local weather forecast), and there’s a big community adding. ![]() I am a big open source fan so I am really keen to get this right and get my home sprinkler project happening. If you hate watering the garden but enjoy messing around with computers, OpenSprinkler Pi is a no-brainer. Would this be suitable for Australia (240V AC) with the right adaptor? – “Single power supply design - the same 24V AC sprinkler transformer powers both sprinkler valves and RPi.”. I want to be able to drive both devices and no more that 4 x 24VAC solenoid valves. Does this mean that I can use the same power supply for the Pi and for the OSPi if I buy the right one? I am keen to just have a single supply rather than one for each. Version 1.5 uses an improved switching regulator and can provide up to 2amp current on +5V line so should be able to drive all RPis without needing external USB power supply.”. – Ray’s comment above says “Also we have started shipping OSPi version 1.5 since a few weeks ago. I have a question that I haven’t been able to answer conclusively based on the info in the forums and on the main commercial page. Noob here, trying to get the right information before making my purchase of an OSPi to use here in Australia. There are so many Pi models and specs vary widely, and with cost increases due to COVID it could even be wise to use a 1 or 2 B model. I’d love some input on which model Pis are being used and any pros/cons that you’ve come across. But I’m still pretty unclear about the pros/cons. The idea of OSPi first came when I noticed that many users were setting up RPi to work with OpenSprinkler. It is based on the design of OpenSprinkler, but its ‘brain’ is an RPi instead of an AVR microcontroller. I’d love to make this a complete guide post about which Raspberry Pi models are ideal to use with the OSPi board. OpenSprinkler Pi (OSPi) is an open-source sprinkler / irrigation extension board for Raspberry Pi (RPi). Please delete the first post if it shows up for you. OpenSprinkler OS3.0 AC-powered (including 24VAC power adapter, US) 166.00. ![]() Then program it either via a RPi or laptop/tablet.Mods: something got messed up with my first topic post, so I’m posting this again. Now, the OpenSprinkler firmware is installed on top of Raspberry Pi OS. Also talk to a thermostat either a traditional 240V one or cleverer. Our app can control multiple OpenSprinklers for limitless expansion. That can hold a schedule, RTC and some relays. OpenSprinkler Pi (Sprinkler Board for Raspberry Pi 24VAC Power Adapter Included). ![]() Presumably the best solution for heating control, like this lawn waterer, is to have a low power controller, such as an ATmega, and some custom electronics+ relays. This causes the poor relays to thrash, which in turn makes them sicker. So their repair is mostly replacing the relays (dead cheap).īecause of the logic states required to run a combie sick relays cause all sorts of problems cos a relay can contact, the board’s happy to switch the next device, and then earlier relay changes its mind so forcing the controller to backtrack. The 240V relays on the edges get trashed. What happens is that the extra-low voltage electronics lasts for ever. There’s a company that sells refurbed boards for a fraction of the price of a new one. Publication date: at 19:25 Published to Thingiverse on: at 10:35. Marginally OT, but the circuit board for a combie boiler wear out after a few years.
