Homebuilt ROVs Forum

Hi, Here is a video from another test of my brushless ROV thruster to see what the maximum current draw is. Ii9ugpGANFM The propeller is attached to the outrunner more securely than most because of the way the NTM prop adapter works. It actually bolts to the face of the outrunner with machine screws...

OK. That makes sense. That design is good for a permanent LED. I believe the LED chips already have some sort of resin on top of the physical LED's, so it should work nicely. I like the thermocouple idea. What are you using? A k-couple sensor of something like this? http://www.ebay.com/itm/10pcs-NTC...

@KR2_Diving, I think that it would be a simpler solution to just have them on off, and it saves space in the pressure vessel. Maybe a LED driver could be an update or in a version 2. @bikerbones1968: I am manufacturing these myself. I have some 2.5in aluminum round bar, and I am using a lathe and a ...

Thanks! It will be just be the LED and a step up power supply. No driver for now, just a SSR relay board for on off control. I am looking a designing a PCB with some MOSFET's, and inductor, and some high power capacitors as a PWM controlled LED driver, but for now I think that on and off will do the...

You are correct. It is a heart beat LED, and actually has two functions. It shows that the Arduino is running and not frozen, and it also shows the communication status by blink rate. Here is my code that I have running in the tests: https://www.dropbox.com/s/l8ljfro9w827sjx/Software%20v2.zip I have...

Hi, Here is a custom ROV control board I designed and had manufactured: r973W29imf0 The PCB takes a power input of 8-12v, and supplies all the electronics on the circuit board, as well as any servos or sensors that are connected to the board. It also has some capacitors for filtering noise out of th...

Hi, I just recently tested these LED's from Bridgelux: http://www.newark.com/bridgelux/bxra-56c1100-b-00/es-rectangular-array-cool-white/dp/73T6218?Ntt=73T6218 Here is a video of the testing: nCe1o55hhH8 They run at 21v and draw approximately 550mA. In the video I was using a Zahn step down regulato...

The GoPro Hero3 Black Edition does seem to have better low light performance. The product description page mentions a "6-element aspherical lens" and "2X better low light performance," here: http://gopro.com/cameras/hd-hero3-black-edition#description However you will need some am...

Hi, GoPro cameras can do TV out(NTSC/PAL) or HDMI while recording/preview/playback. You would need to modify the casing a bit to plug in the cable but it is on the side of the casing, so you can still access the camera/battery/SD card/etc. I think it would work pretty good. I have the white edition ...

Yes. You plug the Cat5 cable from the tether into the computer, and have the Arduino (the one you linked to in your post) in the ROV, and connect motor controllers, relays, servos, etc to the control pins on the Arduino. The software supports an IP camera like this: http://www.ebay.com/itm/NEW-GEN-W...
