A backup camera for $50!!!!!!!!!!!

[rd_macgregor]

I wonder if any portable DVD players or tablets have compatible AV inputs. These devices tend to have pretty good resolution screens and (especially the DVD players) are pretty cheap. Could something like that be used, and give a sharper image than the screens being tried in the above posts? Or, is the innate camera resolution (or lack thereof) the source of the pixellation/fuzziness?

I was thinking about trying this monitor: Amazon.com: 800x480 Resolution 7 Inch Widescreen In-Car LCD Monitor Compatible with Headrest or Stand: Computers & Accessories Pretty much the same one, but the resolution is now doubled to 800x480. Thoughts?

I guess it will be about the same as the one we have but with a higher resolution. IN another thread Eric suggested to upgrade the a/v cable. I think it is a good idea any you may get a little better picture quality. Amazon.com: 3-RCA Composite Video Audio A/V AV Cable GOLD -12 ft: Electronics

The biggest drawback to a portable DVD player would be the bulkyness to mount in a tractor. You can get docking stations for tablets with a/v hookups but IDK if they are inputs. It would take a special app to make the camera work. It also may be hard to keep the tablet in the docking station. I think the camera may be some of the problem. I need to take the time to hook up something else to the monitor and see what the picture looks like. I'm happy with the monitor and camera. All I wanted was to be able to see behind me and make sure I was not going run over somebody or something. I really don't have a need to see far behind me.

First of all, GREAT WEBSITE. Many thanks to all who are willing to share their projects.
Just purchased and bench tested a camera and 7" monitor and all is well at this point.

I'm looking for suggestions on where to tap into the 12v on a Kubota L48. Ill be using the camera on the front end to view the FEL when picking up large rocks etc. I don't have a wiring diagram for the L48, anyone know where I can get one?

Good first step is to check your owners manual for location of your fuse block. Find a source of 12 volts that is switched by your ignition. Neither camera or monitor will draw very much current.

I bought a magnetic camera mount with 1/4-20 stud so I can move camera to different location, on front of tractor / FEL, for various operations. These magnets are very strong so no worries on camera falling off. Also bought a windshield suction cup mount for monitor so I can reposition it for different light situation.

Good luck with your install.

Welcome to the forum. I used a fuse tap to power the monitor. The fuse I tapped was only on with the key on. For the camera I found a hot wire on top of the cab and used it.

I may eventually add a second fuse box for my accessories.

A safer product for tapping into fuse boxes is using add-a-circuit. These things come in all sizes, use the original fuse to protect the circuit you're tapping into as well as allow you to fuse your new circuit. Very handy. I'm a big fan of them.

Here is a mini low profile:

Check under your "drivers side" rear fender. Many Kubotas have a 12v plug there, at least open station ones. Mine was fused to 10@ if I remember.

Those are nice but I don't see how they are safer than a fuse tap. I don't think the add a circuit will fit under a lot of fuse box covers.

+1 for the low-profile mini add-a-circuit that Eric mentions. Agree with Roger that it probably isn't any safer than a simple copper fuse tap. But the simple tap slaves off the existing fuse, and I preferred having the second, dedicated mini fuse that the add-a-circuit allows. (I also left the OEM inline 2A fuse in the monitor's hot lead, after relocating it to the main fuse area, so it's no doubt overkill).

As to clearance for a fuse box cover, it does require more clearance for the cover over the fuses, a bit more than the thickness of the two mini fuses. To allow for the hot feed from the add-a-circuit, which exits to the side, I just cut a 3/16" slot in the side of the fuse cover and it fits fine.

I've added three pics of my installed monitor to give folks an idea of the quality of the images I'm getting. Monitor and camera are the ones Roger linked to at the top of this thread.

The pics were taken with the tractor idling, with a cell-phone camera in bright sunlight (cabbed tractor). The implement under the guide lines is a box blade. The horse trailer in the second pic was about 25-30 feet away. The monitor is mounted to the dash/cowling with four small screws, using the mount that came with the monitor. I sandwiched the included neoprene pad between the dash and mount, but left the protective paper on the dash-side so as not to make it permanent. No idea how long a $28 monitor will last! BTW, vibration has surprisingly not been an issue at all for me, even at full throttle over rough terrain. YMMV.
