Anytime Camera Mod. Another Variation. Front and Rear view camera.

It depends on the camera. if it has some kind of protection then I might not add anything. If it dont have any protection then maybe some clear bra leftovers might help or a custom plastic windshield for the camera.

 

Well since PriusChat was down I decided to see if I could fit the IPA button in the far left hole. It did not fit. So while I was in there I took out the rheostat and tried the IPA in that hole and it fit. Just like it should because thats where its goes in the Euro Prius. So I tried to fit the rheostat in the third hole on the left. It did not fit. So while I was in there I cut a key slot for it and slid it in. Now my dash looks more like what it was meant to be. Now I just need to build that circuit.

Here are some pictures.

I found this the other day and I think I will add it to this mod.

Motion Detection DVR Surveillance Kit

I think I could easily add this to my 2 camera setup. Maybe even add one more DVR and 2 more cameras for full coverage. I think I even might be able to get it all to run off of solor power and a battery backup.

I don't think I would want to move the rear backup camera up there but that would be a good place for one. I'll keep that in mind for a security camera location.

 

OK time to bring this back from the dead. I really want to get this project rolling and need help designing a circuit. If you can help for free that would be great but I would also be willing to pay for your time if you can design the circuit for me. I have posted on one electronics forum but have not got any takers yet. Any help with my project would be greatly appreciated.

It has been about 6 years since I have been in an electronics class and most of the stuff I have forgotten. I do know about resisters, AND OR gates, LEDs, switches, and relays. I do know how to solder, how to use a breadboard and how to route traces on a circuit board. There might be some more lingering back in my brain. The only hard part for me is figuring out how to get the thing to work the way I want and thats why I need your help. I would also like to mention that I have electronics workbench so if anyone could help me out with the design in that program that would greatly help me understand whats going on.

The button is a momentary SPST

This is what I would like the circuit do.
Press button turn on front camera.
Press button turn on rear camera.
Press button cameras off and everything is normal. Car will activate rear camera when backing up like normal.
When the front or rear camera is switched on the circuit will provide power to the indicator LED on the switch.
When turning on the front camera the circuit will provide power to the front camera. ( this is just an idea and not really needed at this point )

This is some snippets from Darell's site about the mod. http://www.evnut.com/prius_mfd_video.htm
The goal for the switch is to selectively jumper the gray wire to the pink wire, and the diode is to keep the reverse lights from turning on. Nothing gets pulled to ground, we're just passing the + signal of the gray wire over to the pink wire to activate the camera and screen. This will activate the rear camera anytime.



The pins for the switch are...
2-7 Indicator LED
3-6 SPST switch
4-5 LED Rheostat controlled. I have this one covered. There is no need to design for this.



I've looked around trying to find a prebuilt switch I could tap into but I have been unsuccessful. I've also looked around on the net to find something to build but still have not found anything. I was planning to use some relays for a simple design but from the looks of it a simple pic controller and a few relays might do the trick but I've never used a pic controller.

I will also need a source for all components used in the circuit along with surface mount RCA and molex connectors for the video and other wiring. The local ratshack wont work for obvious reasons. They might have a few parts but not all.

So can anyone help me?

I hope this is enough information. If i'm missing anything or if you have any questions please feel free to ask.

 

One last mid day BUMP before I give up on getting some help designing a circuit. Can any one help?

 

Thanks Cheap! All those are great ideas! If I ever need to add more video inputs I would just add them to my future in dash PC.

I'm finally getting some help form an electronics forum. They gave me info on what to use and how to use it. With this new info I think I can add up to 8 or 9 video inputs. but i'm not going to get ahead of my self here and i'm only going to shoot for the front and back camera. I may add the option to have 4 cameras. Front, Back, Left, and Right or use the extra inputs for something else.

I just bought about $220 worth of electronic supplies. Powered breadboard, resisters, diodes, LEDs, capacitors, relays lots of relays , OR gates, jumper wires, 555 timers, counter/divider, and voltage regulators. Hope I did not forget anything. I still need to buy some 4047 multivibrators and some AND gates to play with.

Here is my first draft of the logic of the circuit. This does not include resisters, regulators, capacitors ect... It is also missing the debouncer section for the switch. If anyone here has any input or can help on the the design of the circuit it would be greatly appreciated!
