Just bought a board from Rob last night. I was just going to buy a pH board to wire into my DIY controller, but they're clearing out the v1 boards which include a pH sensor as well... I can use the prototype on my garden or something lol.
yes. i too started playing with it, but then felt it was not needed since i had to buy vortechs and they will ship with their own controller. It does not look like anyone except kessil (that too for their a80/160/360/150) has some known external control mechanism. Meanwhile most use cases that i had in mind involving controlling the pumps, is doable just by controlling the power source (like water change)..
ReefOctopus pumps take in 0-10v, as do a couple models of the jebao controllers. I'm looking to bypass those entirely though and directly drive the pumps.
I don't know much about them but it appears the wave makers are controlled using a 0-5v signal to control the speed of the pump. On the WP's I have I checked the voltage coming out of the pig tail from the Jebao controller, one pin was ground, another was 24v and the 3rd was 0-5v depending the speed of the controller. So I hooked up 24v to the respected pins and the signal I connected to a 0-5v PWM pin and it worked great. I removed the pig tail from the Jebao controller so I didn't have to cut the pump cable and marked where the wires went in the controller in case I ever want to put it back. I've mentioned this to others with Jebao wave makers and it was the same so my guess is they all work like that.
The older jebao pumps have an internal controller that works that way but they kept overheating and dying. The new ones appear to be sensorless bldcs, at least by the board markings.
The ones I have are old. It's probably better using BLDC controller, let us know how it works out. A lot of this is over my head, I'm not the expert some might think.
Neither am I, heh - I just know enough to be dangerous. The only reason I know anything at all about motor controllers is because I built an ebike last year.
I can't speak to reef-pi in particular, but as someone who works with these sort of systems for a living - in general, if you power cycle in the middle of an upgrade operation, you're gonna have a bad time.
Sandisk 'Extreme' or Samsung. Be very careful about who you purchase it from though, there's a lot of counterfeits, especially on eBay and Amazon.
Unfortunately, all that ensures is rapid shipping. They co-mingle inventory, it's a problem.
Get Samsung evo or similar class 10 sdk card
It is possible you installed but never restarted ?
Yeah I've seen a few peoples SD card go bad, it's game over at that point. I've been recommending and packaging the Samsung Pro Endurance card, apparently this one is designed for 24 hour read and write but those other cards should be good too. I think you just want a good quality card.
Did at least once via ssh, but tried right now multiple times over the admin menu with repeatable results
