![]() We recommend MPSA14, a common NPN Darlington transistor. This can be done by replacing the traics (i.e. See the blog post here for an example.Ī potentially simpler and cheaper option is to use OpenSprinkler to directly drive DC devices. The basic idea is that OpenSprinkler will control the relays, which in turn control DC devices. The simplest is probably to use a relay board, which you can get from Amazon, eBay and a variety of places. Q: How to use OpenSprinkler to interface with DC devices?Ī: There are two solutions. The stock MOVs that we offer are of type 07D560K. You can solder MOVs by following the picture below: each MOV (blue colored) should be inserted across the top and bottom holes next to every triac. The surface mount versions (including 1.4s, 2.0s, and zone expansion boards) currently have PCB holes designed to fit one MOV per station. MOVs are useful for protecting the controller from impulse high voltages such as lightning. There is no need to install MOVs for fully assembled OpenSprinkler (2.1 or above). For earlier hardware versions, please check this blog post.Ī: From OpenSprinkler 2.1, the fully assembled OpenSprinkler has built-in bidirectional transient voltage suppressor (TVS). Q: Can I power a USB WiFi adapter (or other USB devices) through OpenSprinkler?Ī: This is supported by default from hardware versions 1.42u and 2.0s. Also, if not using the RFM12B transceiver, digital pins D2 and D10 are free in all hardware versions. Note that Arduino analog pins can also be used as digital pins. Hardware v2.0s: (I2C) SDA, SCL, analog A5, A6, A7, serial TXD, RXD, interrupts INT0, INT2, digital D14, D15.Hardware v1.3u: (I2C) SDA, SCL, analog A1, A2, A3.Hardware v1.2u: (I2C) SDA, SCL, digital D2, D3, analog A1.Hardware v1.1: TXD, RXD, (SPI) SCK, MOSI, MISO, (I2C) SDA, SCL, digital D3 and D9.Hardware v1.0: TXD, RXD, (SPI) SCK, MOSI, MISO, (I2C) SDA, SCL, digital D3.Please check the PCB image of each version, and the available pins are all marked in the pinout area. You certainly have my sympathies.Q: What pins are available for connecting to external sensors and/or circuits?Ī: The available pins depend on the particular hardware version. I think some of the papers have lawyers who answer condo law questions and you may get some free advice this way. Maybe you want to write to the star or one of the papers and ask their lawyers. You won't be popular in the building but this is your best bet. I think at this point, you should ask that they close the pool, drain it and have it fully inspected and remediated. The above said, it is certainly not reasonable after 5 leaks to have you keep putting up with this. Unfortunately, short of hiring a lawyer, expensive for you (and you and all the other owners will be paying for the condo lawyer to fight you), you are really stuck I think. The problem is that the new buyer would have to buy the explanation that the problem existed but it has now been fixed. I hate to say this but when the problem is fixed for 6 months, I would seriously think about selling and getting out of there. If not, I would think that you should be in a position to demand that the condo corporation pay for you to live elsewhere while damage is repaired (which costs all of your fellow condo unit owners and you money to be remembered) and that they make good on the repairs going forward. However, after 5 attempts, you have a right I would think to insist that a structural engineer be brought in with expertise in the field and that a proper remedy done. ![]() Now, at least they are trying to fix the damages. That said, the building cannot guarantee 100% elimination of future leaks and I am sure that you realize that.
