Wow...M1.2 fasteners? Those are tiny.
I don’t know for sure , I was thinking of plexiglass . I am also thinking, do we need panes ? Like what if we just mount the pi / hat / PCb straight on the frames and do very good job of wire management, but no walls
I'd worry about corrosion with an open housing, unless it was a more remote location to the tank
Fair concern, the controller will be inside the stand. I have two backup controller built using uxcell plastic enclosures . .. for the new stand I,lol use those . I could reuse my existing controllers , but since they won’t be together any more , the current setup won’t work ( they share a single Kessil controller ) . I am also aiming for but harder livestock , thinking of seriously giving across a try in one of the pico tank.
Totally , are you still selling the AcroStar led strips ?
I have kessil a80 already which should be ample (that’s what I felt ), at 15w, but I thinks it’s too spread out , and the pendant effect is another worry . But for pico form factor this may be ok, and in that case I need something with narrow focus like 40 to 50 degreeStrips needed a re-design to be viable, so I pulled them for now. Always happy to add some of the original models though since I do have the parts. Most people liked the dense pucks, which would be pretty nice for a pico tank
The pico tank is 11 x 9 inchesMakes sense - let me see what I can whip up for this with a large diffuser plate. If you know the overall surface area of the aquarium for the light it would help
Can you check with multimeter that outlet on/off working as expected on the connector pins in the relay (i.e. you are getting 12v or on at the other end of the connector wire, right at the junction of the relay)?I got a lot put together tonight and there is a lot going on in this pic lol but the PCA9685 is working as expected, doser pwm is working, all my gpio pins trigger like they are supposed to. But of all things the stupid relays I added are not working.
They are 12 volt opto isolated relays that have jumpers for both high and low level trigger. Since it’s running directly off the gpio I have the jumpers on the relay set to high. The relay shield has power and lights up. If I switch the equipment tab in reef-pi to on, the led on the relays light up but no click. If I change the jumpers to low level trigger they turn on and click as soon as the RPI has power I tried another relay shield same brand and get the same thing. Any ideas?
Use a npn transistor , exactly same as the Kessil controller circuit
Yeah you want to use the low level and it should work, in reef-pi you may need to use the reverse setting in the connector settings setup
Keep us posted on how this goes...and now for my next trick... hacking an eheim feeder to run off reef-pi!
