Horerczy Posted June 4, 2013 Share Posted June 4, 2013 Finally got all my parts in and sat down look look at everything. I have no idea what I'm doing. 1 Quote Link to comment
MeepNand Posted June 4, 2013 Author Share Posted June 4, 2013 Finally got all my parts in and sat down look look at everything. I have no idea what I'm doing. No problem. I found a video camera, so expect a video. Also, my last final is over tomorrow, so I'll have more time open for projects. I need a credit card... 1 Quote Link to comment

Confuse Posted June 5, 2013 Share Posted June 5, 2013 So I decided to use your controller for my evil cluster. I'm waiting for the LDD boards, so I'm trying to be productive in other areas. Today, I received my SaintSmart and didn't order the power supply. I thought I could use an AC/DC adapter that I already owned, but I'm not sure. The one you listed is rated at 5V/2A. I have a few loose power supplies but they're 1A; one is 12V 300mA output. Can I use a lower rated power supply or is there a reason for the 2A power supply. I know next to nothing about electronics, so I was trying to save a few bucks and time. But well....looks like I didn't. 1 Quote Link to comment

The amazon power supply listed didn't fit my sainsmart. annoyance of annoyances. gonna look into one of those adjustable voltage dealies. 1 Quote Link to comment

I said 5v 2a because the tft uses a lot of power, but I don't know exactly how much. I think a 12v 1a would work, but again, not sure. TO HORERCZY: I'm sorry, I forgot to tell you you have to solder the power supply. I'll update the first page. Quote Link to comment
sdeverson Posted June 5, 2013 Share Posted June 5, 2013 It uses pings to measure distance. I found a bit of info on Arduino Basics that says it's been used for mesasuring water levels so I would imagine it's posible to make it work in this application. The SRF-06 version would be better though as it has a temperature compensator. In the end though the simplicity of a float switch will probably be best as the ultrasonic sensors would have to be calibrated on a tank by tank basis. Those devices work like echolocation....it sends a ping out and then measures the time it takes to get back and converts etc...we use them in our physics labs to measure velocities and such. 1 Quote Link to comment

Cool! I was actually thinking about something else the other day... I think it was a visual aid for blind people? Quote Link to comment
Confuse Posted June 5, 2013 Share Posted June 5, 2013 Ok. I can confirm the 12V 1A power supply works. Everything turns on. Nothing showing on the screen, but it does light up. 1 Quote Link to comment
Confuse Posted June 5, 2013 Share Posted June 5, 2013 This is probably a very stupid question, but I'm having a hard time attaching the TFT on the shield since the timekeeping chip is somewhat in the way of it. I have the same timekeeping chip you listed on the ebay link. Am I making any sense? 1 Quote Link to comment

I have the same timekeeping chip you listed on the ebay link. Am I making any sense? You should be connecting the timekeeping chip separately. If you already are (most likely) then you need to desolder. If you have pins coming out of the shield and going into the pins where you would normally connect the DS1302 and stuff, then you could either A: desolder the pin header (tricky, but if you have a solder sucker you can pretty easily) or B: solder the wires on top of the shield. That's basically it. Sorry. Quote Link to comment
Confuse Posted June 5, 2013 Share Posted June 5, 2013 Ok. So there's no way around soldering. Can I just attach the right angle headers to where the timemodule goes and solder wires to it? I'm afraid of desoldering... 1 Quote Link to comment

I'm afraid of desoldering... that was basically what I thought about doing. right angle headers all around where the shield wasn't just in case I needed the slots for something. 1 Quote Link to comment

Do you have a picture of how you have it connected? I assumed that I put the right angle headers where the module attaches and run wires from the end of the headers to the module. 1 Quote Link to comment

I'll just find an appropriate power source then. With my luck I would cause something horrific to occur if I tried that. 1 Quote Link to comment

Would you happen to have a higher resolution image of the connection diagram on the first page? I found a diagram on the time module, but I wanted to compare. 1 Quote Link to comment

Confuse Posted June 6, 2013 Share Posted June 6, 2013 Okay, I'm not too busy today, so I'll get around to it. Hold on an hour or so. No rush! My LDD boards are still in China. Haha 1 Quote Link to comment
MeepNand Posted June 6, 2013 Author Share Posted June 6, 2013 Just wired it up, and I see what you mean. Doh. I removed the female headers on the analog pins and soldered them out carefully. Then I replaced them with the right angle headers. 1 Quote Link to comment
MeepNand Posted June 7, 2013 Author Share Posted June 7, 2013 Here, I wired it up. My clock is acting up still though, and I can't figure out why. No updates till fixed. http://s1265.photobucket.com/user/asid61/library/Projects/TFT%20controller%20aquarium?sort=4&page=1 Quote Link to comment
