Reef Angel Forum

Ha! I learned what I know from this forum. So maybe I'm a padawan to the jedi masters.

A couple of things to consider... 1. I used a pull down resistor as in the desription here http://learn.adafruit.com/photocells/using-a-photocell . 2. I 'hacked' a wire to the analogue pins of the I/O chip. I think you could also get one modified like this if you want. 3. I wrote my own code to send...

I ordered the photoresistors here....

Wouldn't you know it, right after I put these together. Although this was really cheap to make and I know it gives me a variable readout. I wonder if these will do that as well (the description just says Day or Night reading).

-Jon

I was wondering about my ORP as well. I don't know a lot about this sensor, but I'm guessing it shouldn't look like this.... I tried moving it to another part of the sump, but I still get these sharp drops that don't seem to correlate to anything.

Should I try another probe?

-Jon

It would be very cool to measure PAR, but these aren't quite in that spectrum. There is a long discussion on the topic here http://www.plantedtank.net/forums/showthread.php?t=120109 . I just wanted a light meter to know for sure the bulbs are on and maybe pick up some loss of intensity over time to ...

Hi all, Awhile ago I was working on a light sensor for the aquarium. http://forum.reefangel.com/viewtopic.php?f=19&t=493&p=4008&hilit=cds#p4008 I finally got around to setting it up last weekend. I thought I'd share it with you all. I like that I can actually confirm the lights are on an...

That is pretty slick. For $7 it is worth a test.

Why aren't you using the DrawSingleMonitor function for the temperature?

More fun with Arduino :D Awhile ago I posted my first DIY project that plays sounds and can be triggered from the RA unit http://forum.reefangel.com/viewtopic.php?f=4&t=584 . It is fun and cool to show off when guests/kids are over, but I got to thinking it would be really cool if it could liste...

Hey all, I was trying to make some updates to my auxillary monitor (original RA connected to the I2C), but ran into some problems. When I uploaded the ino to the second monitor the main RA+ kind of goes nuts with relays turning on and off quickly. This doesn't happen when all I load into the RA is a...

I guess I should have waited on trying to make the arLCD work. ;) I haven't got much feedback from the EarthLCD folks on this, but maybe the libraries/widgets will improve over time. I'm sure you'll be able to produce a much better expansion module as well. I think the ability to display tank parame...

I am trying to send some text characters over a serial connection and display them on the LCD screen. I can send numbers across and display them with DrawSingleMonitor,but I haven't had much luck with text. It displays correctly on the serial monitor, but I'm guessing I'm losing something in transla...

yeah, you can't see the 3 power strips underneath all that for the fluorescents, halides, and the rest. I also didn't have the dose pumps plugged in for that picture.

-Jon

wow, I really need to work on this. and this was a cleaned up version. It's tough to fit this all under a 75g stand with a sump.
-Jon

I'd say that's half the fun of the RA. I've added light sensors, water (leak) sensors, power sensors, and flow meters in the last year or so and everything I needed I learned from the experts here.

-Jon

Thanks! Works perfectly. I am able to use the Touchscreen to toggle the relays. I just need to figure out how to get it to display multiple screens for both showing data from the main and controlling relay from the Touchscreen. The arLCD works at 38400 baud and is really awkward requiring delays in ...

Would something like this work? ('borrowed' from the wifi library) I'd put this in the master and send the relay position and status if changed on the ezLCD button. void loop() //other stuff GetRelay(); if (lcdtype==0) // Turn port off { if ( lcdrelay < 9 ) { bitClear(ReefAngel.Relay.RelayMaskOn,lcd...

I'm still struggling to understand :? how to send the correct byte of info as a mask command over I2C to turn off a specific port without effecting the others. It was easy with the RA secondary screen unit because I had the TempRelay functions on both sides to convert the byte sent. I actually have ...

Thanks. That should work. I did this to send the temp relay data to the second monitor (my original RA), but I didn't really understand the conversion sending the TempRelay byte to the 2nd monitor and it reading it as a bit mask. Since I'm trying to go the other way trying to send the mask to the co...

Hi all, I am working on this touchscreen http://forum.reefangel.com/viewtopic.php?f=4&t=452&start=30 and I was planning to try to use a button to have off/on override of the relay switches like you can do from the web/portal/phoneapps. I was thinking I would need a series of if/then statemen...

FWIW, I find many times that more menu's or nested menu's would really come in handy. However, I expect I am using a lot of features maybe others aren't. I'm essentially getting extra "read only" menu screens with my second monitor set up. I've thought about trying to make it send info bac...

I need another IO outlet and I was thinking about my options. I could just order another IO expansion , but I only need one extra. I could run a wire to add a pin to the current IO (I think). But, since I am using my original RA as a secondary monitor, could I also use the ATO, pH, and Temp ports of...

It's great to have your talents here again. Sorry to hear about the accident, good to hear things are getting better for your family.

Jon

I just got back from 10 days in Israel and everything still looks great.  Fish are fed, temps stable, and ato's topped off the water.  Another couple days and I would have needed to refill the top off reservoir. 

Thanks Roberto and RA for piece of mind and a healthy tank while I was away!

Jon

I forgot to mention, that the 5 & 6 ports are wired specifically for power head cycling and you may have some issues with using 4 & 7. I'd ask Roberto. You should be able to run more than one power head to a port with a power strip or extension though. I actually got a second box so I can pr...

I started using the EvoCam software for my tank web cam and you can run timecourse movies. It's pretty fun to see how busy the tank is when the whole day is crammed into a 1 minute video. http://youtu.be/E77iXpYzwLI

-Jon

I cycle my Koralia's every 200 seconds. It may wear them down faster, but they are cost effective.

Jon

You could work from this to get an ellipse...
