absolut_racer Posted January 31, 2013 Share Posted January 31, 2013 Just found this topic. I am interested, as I have some downtime. Here are my current skills I can offer: Basic electronics (circuits, soldering, battery building, etc.) Manufacturing Materials and Processes Data Modeling VBA, JavaScript, HTML/CSS, C++, Basic Shell Scripting, etc. Mechanical Drafting (AutoCad, Solidworks, Pro/E) Link to comment Share on other sites More sharing options...

Stephen Posted February 1, 2013 Share Posted February 1, 2013 Capt, I’ve been trying to plan ahead with my future arduino build and wanted to run a few things by you before I order more parts. Current Parts: Funduino Mega 2560 Temp DS18B20 Time Clock DS1307 Male/Female Jumper Wires Are you familiar with 4 Route MOSFET Button IRF540 V2.0+ MOSFET Switch Module? I was told that I can add this to the arduino to function in place of mean wells for my leds. My goal is to be able to program a sunrise-sunset program and to be able to control 3 series of (12) 3w leds independently @700ma. What do you think of this 16 pin lcd? http://www.ebay.com/itm/New-2004-204-20X4-Character-LCD-Module-Display-For-Arduino-/350560713502?pt=LH_DefaultDomain_0&hash=item519f0bfb1e Other ideas: Ph Probe Temp/heater control program Wireless access Keypad Alert commands Good place for code: http://reefprojects.com/wiki/Code Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted February 1, 2013 Author Share Posted February 1, 2013 Stephen, are your meanwells the -D type or the -p type? The Lcd is a standard 16 line module, looks pretty good, there are some that come with 4 buttons, which helps for navigation Some of this would be better to discuss via PM/phone as we can get into more detail Link to comment Share on other sites More sharing options...
Stephen Posted February 2, 2013 Share Posted February 2, 2013 I haven't bought any drivers. I was looking at the ELN-60-48d and p, but I was told I can get away with using the MOSFET instead of drivers. Similar to this http://m.youtube.com/#/watch?v=8JQBkOU6K5Q&desktop_uri=%2Fwatch%3Fv%3D8JQBkOU6K5Q Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted February 2, 2013 Author Share Posted February 2, 2013 This appears to be what is known as the NFET(MOSFET) + NPN(resistor) (+ sometimes a Zener diode) method... From what I can tell from the video. It would work and is very cheap to make...however the downside is that it is fairly inefficient (wastes power) If you do get meanwells, get the P flavor Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted February 2, 2013 Author Share Posted February 2, 2013 Let me clarify that efficiency statement : for maximum efficiency, you should configure your LED string so that it is as close to the power supply voltage as possible. Other wise power is dispensated through resistance (aka heat) Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted February 6, 2013 Author Share Posted February 6, 2013 I have lesson 1 but the video requires a bit of editing, so, hold tight and I should have it up by tomorrow night Link to comment Share on other sites More sharing options...

Other wise power is dispensated through resistance (aka heat) So I would need to keep the controller and power source as close proximity to the led strands as possible? I am thinking about building my controller in my led fixture and having the lcd screen/buttons on the outside. Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted February 6, 2013 Author Share Posted February 6, 2013 no...close not as in physical location but as in 14volts is not close to 5v etc Link to comment Share on other sites More sharing options...
+Capt. Obvious Posted February 7, 2013 Author Share Posted February 7, 2013 here is the first part...sadly still need to do the screen capture of the code, as that part didn't come out right http://www.youtube.com/embed/q_1bc6cEHZo Edit: not sure why I cannot embed a youtube video....

+Capt. Obvious Posted February 7, 2013 Author Share Posted February 7, 2013 Yeah, I'd love for you to join the ride, but...school first. If you can do both, go for it...but shelf this project if it starts to interfere...or just do what bio said Link to comment Share on other sites More sharing options...

+Capt. Obvious Posted February 7, 2013 Author Share Posted February 7, 2013 A ds18b20 waterproofed and a 4.7k ohm resistor to start Link to comment Share on other sites More sharing options...
aggieMEDIC Posted February 8, 2013 Share Posted February 8, 2013 I am in for the ride. Bought an arduino due what else do i need? I got the due also so we can help each other with issues. Fyi. I found out that inputs and outputs one the due are 3.3v not 5. So we will need to drop the voltage somehow, where necessary. Link to comment Share on other sites More sharing options...
Bogdan Posted February 8, 2013 Share Posted February 8, 2013 I don't know if you are aware that there is actually controller made on the base of arduino, it is Reef Angel. I am using this controller and I am very happy with it. It is run based on the open source software and covers all possible gizmos you can imagine in the reef tank. It is constantly improving and expanding, also is relatively cheap comparing to other controllers on the market. Check out the website and forum and you will find a lot of help even if you plan on making it by yourself. http://www.reefangel.com/ Link to comment Share on other sites More sharing options...
HaysStanford Posted February 8, 2013 Share Posted February 8, 2013 perhaps we could add an arduino controlled nano cooling unit using this? Link to comment Share on other sites More sharing options...
scubasteve92 Posted February 8, 2013 Share Posted February 8, 2013 AWESOME!! I am ordering all of my stuff very very soon! Focus on school make this a reward for midterm to buy then semester to build? I agree.. I just easily get wrapped up in things like this. I will be along for the ride, but I will hold off on ordering one.... for now.. Link to comment Share on other sites More sharing options...
