Anyone built an endoscope thingy?

Hi All,

We live in the boonies and rats chewing wires and hoses on vehicles is a "thing." I need to search for any such wires in nooks and crannies of engines and under dashboards.

Has anyone interfaced something like this with a Nano or Mega and 2.8 or 3.2 TFT screen?

Can anyone suggest libraries to use, such that I can do it myself? I can live with jumpy video if the Arduino are not fast enough. One pic every ten seconds would be fine.

I used the search here and it is totally worthless. Gave me about 30-google ads for bore-scopes and nothing on making and endoscope with Arduino. Good for google, useless for me.

Use a mobile phone, USb OTG adapter and a webcam app.

{grin} Clearly based on the assumption that everyone has a mobile phone and a tower for it to connect to. Out here in the boonies one of those just makes a nice coaster for a can of beer. I could buy a ready made bore-scope cheaper if I had the ready cash and the will to throw it that way.

Your assumptions about our assumptions might be correct.
Posting on here generally means you have access some sort of device that connects to the internet. That amazon device you linked would work with a $50 android tablet also sold on that same site.

But it’s possible you simply writing notes and using Courier pigeons to send them to someone living in the big city, guess we could assume that too.

There’s not really a place for Arduino in this project. You need a camera and a way to display what comes from it. Neither of those things would involve Arduino at all.

What role we’re you envisioning for Arduino? Or was this one of those, “it’s a technical project so Arduino must fit there somewhere” kind of questions?

Couldn't the courier pigeon carry the arduino? How does a swallows air-speed velocity compare to a pigeons?

Ahh, the noisy choir, I had almost missed you all. Yes we have Internet DSL at 2M/s and only about 23-hours out of every 24, that's using copper wire you know. Monopolies thrive in rural areas and no need to eat into the CEO's bonuses, "what are the turkeys going to do? Send smoke signals or be happy with what they get," prevails. {sigh}

If the food supply dried up the Cities would probably take a little more notice of the boonies, but that will never happen as farmers actually care.

OK, now to the Math. A $50 single-purpose phone or a $3 Nano and $12-TFT. Hmm, yup, where's my check book.

@Delta_G: Yup, guilty as charged. My technical project thinking always turns first to the ubiquitous Arduino. But after posting this I considered a Pi and VLC. Almost hindsight in a way. But maybe an Arduino approach is not all that silly.

The crux of this exercise is allowing the camera lens to get to the difficult places without having to disassemble 20 other parts fist. So, even if poke thing thing in then click a button to see what the camera sees. There is no fun in spending an hour to remove parts only to find that the rats have not expanded their territory there -- yet.

But as mentioned, I will try the Pi Zero as I have one here somewhere. Didn't like them, still don't, but may have to give them their due just this once. :slight_smile: Thanks for thoughts though.

Amazon lists about ~100 amazingly cheap endoscope cameras.

I'm left with the same question. What role will the Pi or any processor play in this? What computing needs to be done? You just need a small camera, a video cable, and a monitor. What do you think you need the processor for? That's the question. I wasn't trying to berate you. I was actually asking a question. One that I'm still interested in the answer to.

I don't think you need an Arduino, or a Pi, or any other processor for that matter. You just need a small camera, a long video cable, and a monitor. What do you think you need the processor for? What role will it play? What will it be doing? Calculating digits of pi while you look at the camera? Do you want the Arduino to serve as the on-off switch or something? What role do you see for the processor?

To be fair, the camera he cites functions as a Webcam with a USB interface. So if he is to use that one, he needs a microcomputer with a USB interface and a digital video output. A Pi Zero would fit that bill, coupled to a HDMI monitor of course. Obviously not an Arduino as they do not have HDMI video outputs even if they do have USB Host functionality.

And the fact is that most of these available devices - other than assembled inspection camera systems - are in the USB format.

That depends: do you mean an African or European swallow...

Wouldn't it be cheaper and easier to use a camera that didn't have this requirement and could just plug right into the monitor?

I still don't see any need to have a processor here unless you want to have a nice game of chess (or maybe thermonuclear war) while you search.

I was thinking of another Python sketch.
