Lookout's new adventure

Got a new toy today, of to get some small bits then time to drill the pcb.

Got some stuff done this weekend, all the light "pods" are built. Eteched another pcb but ran out of parts. Need to order a few more things for it. Changed the plumbing around.

Did you check a power off situation? Granted it's hard to tell from the pictures, but that last picture looks like you'll siphon your entire tank empty if the power goes off.

That would be a bad thing indeed. You will see that the pipe goes down into the tank also has a straight piece that goes to the right then angles down. This is a flapper style check valve but backwards. Basically when the pump is on the check valve will be forced closed so no water will come out of it. When the pump turns off the flapper valve will open and let air in. This is my solution to not drilling holes in the side of the plumbing as I have never liked doing that. Yes you should not depend on check valves, because they can leak when closed. If this valve does leak, it would just go into the tank.. no big deal. I have never heard of a flapper check valve being stuck closed. post number 128 shows pictures with the pump on.. and off.
 
Hmm interesting way to dealing with things. Definitely an outside of the box thinking method. Just hope crud doesn't get pushed against the valve and jams it shut over time such that it couldn't open.

I have never heard of that happening. Also the body of the check valve does not really get any water in it. The check valve is clear so if it does start to get dirty, it has true unions on both sides so it can be cleaned.
We will see, If it does not work good I can alwasy change it. The only way you ever know if something is going to work is to try it :beer:
 
I got the rest of the parts for the control center. It is 95% done. The rest I will do once I mount it. The control center is going to swing down to allow me access to the back side for additions or troubleshooting. Also when I went to the electronics store, I had to spend more money since they only accept cc when you spend over so much ( I never carry cash) So I got a roll of 1/4'' copper tape, guess I am going to be making a water sensor now.

Here are some new photos.. Sorry they are with my phone.. i broke the lcd on my camera..

Ok so I am still havin problems with my board. the voltage is droping to 4v instead of staying at 10v. I am trying to figure out why. If there are any electrical enginers reading this.. please pm me if you would not mind.

Thanks

So I think I came up with a solution. Right now I am trying to use 1 voltage regulator for all 18 7667's. The voltage drop is way too high. I could get a higher voltage regulator but then trying to figure out which one I need so all the 7667's only get 10v, this is beyond me. So I am going to give each 7667 its own voltage regulator. This means I have to re-build the pcb and wait for more parts to come in. If anyone can chime in and tell me yes or know on this.. That would be great.
 
Not meaning to put you off or anything, but the the DIY forum is full of people who are into this sort of thing. You might get more knowledgeable help there on LEDs and in the RC3A sub-forum on controllers.

Really happy to see you doing all of your own work. A lot of custom parts on this tank, that is what i love to see can't wait to see it all done.

Thank you Dave, I thought people frowned on putting a question in multiple forums. Will post it over there now.

Thank you Dellyjoe, Getting closer every day. I dont want to give anything away, but if the top of my tank works the way I want it, It is going to be awsome! :)
