Can anyone head me in the right direction please?

I want to build a simple video camera and monitor screen.

• 12v (for automotive application)
• Wired (not wireless)

 

Often wondered why people don't just buy stuff unless your wanting to design one yourself as a product to sell.
All this is up to the person though.

Car backup cameras are under $10 on eBay. They are 12V power and video output. There are many different versions, all around 1MP. Most have (optional) lines added to show lane limits, some have wide angle lens, IR leds, waterproof etc. I would get one of these. For the price they do very well.

I'm interested in gathering the componentry and assembling it into a working video system.

I know I can buy one cheaply off the shelf but I'd be none the wiser about how it works.

This is a build project. Can you help?

No interest in selling.

My only interest is learning how it works and in the satisfaction of making it work as an accomplishment

Hello Dendad! Hope yre well. Just drawing your attention to my post. Thought you might be able to help.

I saw a contribution you made to a similar thread - see attached screenshot.

 

A lot depends on just what you mean by...

I want to build a simple video camera and monitor screen.

At what level do you want to start?
For example, are you intending to build the camera sensor? Then go on to constructing some sort of display?
Or are you wanting to buy a camera etc. and put them into a case?
You do need to define your question quite a bit.
And, there is nothing "simple" about trying to actually build a camera and display.
We may tend to think they are simple because the packaged items look that way from the outside, but to actually make them from scratch is a massive undertaking involving many man years.

As mentioned above, look for reversing cameras on Ebay.
To buy just the sensor alone would probably cost you more than the whole lot. Then there is the lens, LCD display and all the electronic parts required to drive both.
Even going from data sheets and application notes, if you can find them, you would need to develop a working circuit and draw a PCB and get it made.
It is so not worth it! And way out of your expertise.
As I have said in a couple of posts, they are not simple!

My thoughts were them being so cheap you could use one as a template. Just think of all the work you would have to put into this.
Component selection, component equations, PCB design, wiring (inside and out), enclosure design. It's a lot of work and time.

For $10 or $20 bucks you could see how they done it and it might give you some new ideas is all I'm saying.
You could see what components they used and might even say I can make it better or use a larger screen.

There is a method to my madness.

Yeah well said @dendad having now read yr suggested downloads... and looked into it and read other AAC replies, well, ummm ... I don't know what I was thinking TBH

Still, asking questions however dumb they turn out to be is all a learning opportunity

Thanks B
Took yr suggestion. pulling one apart I just got from eBay. Holy complicata!!
Thanks but no thanks

@Mellisa_K
I wasn't trying to make you not want to do the project. Any project takes a little time and effort.
Don't sell your talents short. When I started my project I knew nothing about electronics....At least you have one up on me!
From here on I might not can help but the folks here are "One of a kind" and will go out of their way to help you.

I say go for it!

Just out of interest, have you see the old project about turning a flat bed scanner into a camera?
It may be something you could have a play with as they are tossed out all over the place.
Here is one article ..

Mellisa,

I admire you for wanting to do this, and wish you success-- but the fact that you are asking suggests you aren't very familiar with the actual scope of said project. A miniature camera needs both a lens, and a highspeed MCU that can read and process the information it returns quickly enough, and then turn around and display it quickly enough. This is not a trivial project, and you really have to know what you're doing code-wise for performance.

I recommend you start hunting down data-sheets for CCDs. because this will let you pick the sensor you want, and feel you can manage- and then choose your other parts around it.

Here is one: HDCS1020-2020

Start small, with like 640 x 480, and see if you can see your way through the requirements for managing that. Arduino won't get you there- you're going to have to use C and know how to write efficient performance code. Don't count on MCUs being much faster than 16-20MHz, because time is your greatest hurdle.

Wishing you great success- if you get frustrated, ask. Or shelve it until you know more. Nothing make someone learn like pushing themselves for a project they are passionate about!

+1 to that.

 

Just out of interest, here is some pictures of the "camera" I helped design in 1991. It was for sorting fruit in a cannery.
It actual worked, in a kind of fashion. Much to my surprise. But the picture was pretty poor quality.


A close up lens screwed on here.

And this is all the driving hardware...

As it stood, this is only part of the camera. It plugged into a main board that was was driven by an RTX2000 FORTH engine.

Here is the next model CHRIS board, (Colour High Resolution Imaging System), I drew in Nov 1994.
My wife is Chris, so some points were gained there
This board went to a frame grabber (Bt254KPJ20 plss support chips) and a commercial camera.


On the other side is an I/O board (also running FORTH) that reads the shaft encoder on the convener belt, and drives the kickers to direct fruit to the appropriate line.



This sorted half peaches and pairs by colour, size and blemish and at around 5 pieces a second, if I remember correctly.
Not too bad for a processor that ran at a 12Mhz clock speed.
There was a Harris HSP48410 hardware hystogrammer chip to help, but the next version went to a Linux based 1.3Ghz processor.
The RTX2000 FORTH chip is pretty cool.
I still have a couple of tubes of new RTX2000 chips, along with most of the parts to build more. It is a pity it was dropped eventually, but going the way of commercial cameras makes a lot of sense as they are not quite straight forward to build to have good performance.
