DIY USB soldering microscope

Ok, stumbled across this…though it might be helpful for those that might need some assistance seeing small components

http://www.thingiverse.com/thing:2083614
http://operationalsmoke.blogspot.jp/2014/05/diy-usb-soldering-microscope...

from his site

Quote:
I’ve been looking for a decent and cheap USB microscope for SMT soldering. Many of these 50-100$ Chinese microscopes have quite poor working distance, resolution and image quality so I thought to try make one by myself.

A webcam should work quite nicely as a camera sensor because they should work almost everywhere without fiddling with drivers or viewing programs. Logitech C270 is quite inexpensive and it have 1280×920 resolution. A bit of googling also revealed that it doesn’t have any too fancy autofocus features that could cause problems later. Estimating the delay between camera and monitor from internet reviews was quite hard but it seems to be in tolerable level.

Most incredible part… Total: ~ 63€ / 86$

And focal length is incredible…no more 3-4” of space…just look at how much room you would have to solder!

That’s a huge space to work with!!!

Just thought you guys might be interested

I could build one of those… then let you swap cheap lenses…

mine? would feed a standard A/V signal… i’d watch it on my own screen, but, you could watch it on whatever you wanted.

zooming in and out would be possible…

its basically a cheap security camera, and, a camera lens.

With enough black coffee and cigarettes? all things are possible…

I am currently still shipping… REAL GENUINE CREE xp-g emitters, the classic… brace yourself? as low as 20 cents apiece!! Check out the SALES THREAD, everyone is happy… then PM me

Now there is something which my tired old eyes can actually see well Thumbs Up It’s on the dream-bucket list, just can’t spend that much for something like this without a lottery win first.

I just bought a microscope but it’s still in the mail – 500X version

The 500x version says 10mm to infinite focal distance. I figured that means I won’t have an issue with working space. I hope it works as expected…

Thanks for sharing, WarHawk-AVG.

The workspace and depth-of-field are really impressive. I use an Andonstar 2 MP USB microscope and although it is very small and offers a few inches of workspace it is difficult to focus properly.
I wonder if I could use one of my old analog camera lenses instead of a CCTV lens…

Edit: The answer is yes. Here is an improved version.

==================================================

definitely.

if you know the size of the sensor, and the Focal Length of the lens… you can calculate the field of view, and express it in whatever units you find useful… EG, 12 feet at 100 yards, or, 1.2 degrees at 100 yards

i wanna remember that you just google a “field of view calculator” and you’ll get multiple hits… security camera sales places trend to have them, to make it convenient for customers.

===================================================

the SAME exact lens, on two different security camera sensors? could have different “power”. The lens just projects a picture back onto the area of the sensor, some of which lands on the sensor and some of which falls around it wasted.

different size sensors, have therefore different fields of view (and apparent magnification). I tghink its also called “crop factor”, but dont quote me.

camera and security camera guys? plan this out thoroughly, lol…

well, you will think i’m silly, but what does the Focus ring on camera lens do
it isn’t autofocus, right, i have to manual focus, does the focus ring change anything

In this instance, auto focus would not work so you would have to use the focus ring to focus manually

The microscope I ordered arrived today.

Whilst it does ‘work’ it is far from ideal. Also far from advertised specs – advertised 1600×1200 30fps max resolution – reality 640×480 25fps

I can adjust it so I have enough clearance to do solder jobs but the resolution is so grainy I might as well be looking straight at the work.

I’ll see if I can add a lens like OP and/or replace the current plastic lens …. or I could just send it back and tell them it’s rubbish Flat Stare

Sorry it was too late to warn you. Sad

When I was looking for a USB microscope I found this video comparing yours (sort of) and (now) mine. The Andonstar is much better but still not great for working.
I think you (I) will need a strong far-away lens (as the project in the OP) or either working distance or depth of field are too bad to work.

I know professionals use binocular microscopes for soldering but these are far too expensive for me as a hobby tool. Maybe one of my old SLR lenses will work with a webcam.

so… basically, if i MAKE one of these contraptions… what do you guys WANT in the way of specs?

1) you want high resolution, the higher, the better
2) you want “work space” under the thing
3) you want to zoom in and out, from lower to higher magnification

what else?

I’m on the tail end of a long project, and honestly, THIS device is something i could have made early on in my project.

I salvage lenses, plastic or glass, from any device i find for scrap… and i can grab several of them, and put them all into “one lens”, kinda like i made my own camera lens.

magnification is just a number to me, in THIS case… because you are not wanting for “more light” at higher magnifications… (I am pretty sure? no one here will hve trouble getting enough LIGHT at higher magnifications, call it a hunch, haha)

===============================

what do you guys need/want? it will be manual focus only. I am seeing giving the ability to swap commercial lenses that are affordable being cool… although for MYSELF? I would just have several different FocalLength lenses laying around, in plastic carriers that i would swap out for various magnifications.

I had no idea something like this was needed or wanted…

all this is, is macro video photography…. i normally do all this in infrared, doing it in visible spectrum would be a lot simpler… would black and white be okay with high resolution? or is color a must?

After experiencing the POS for me resolution is priority #1. The 500x zoom (I now have doubts about this figure) is useful range but the microscope had to be right up close to get any decent resolution.

well… every optical device works like that…

take a picture of me at 100 yards,and take a picture of me at 10 yards, and which one has better “resolution”? definitely being closer to your target gives you more resolution….. what you are saying is that you wished the focal length of the lens was more…

how small of a “thing” do you need to fill the screen? A quarter? A dime? a pack of smokes?

you cant send a ball peen hammer to do a sledge hammers job… i could see about running a test with, say, a 600mm or 800mm focal length lens…

just tell me… what size “thing” should fill up the screen… penny, dime, pack of smokes… what? That will give me something to go on, so i can mock something up to see if this will work.

=============================================

sounds like you need more magnification from farther away, lens-to-target distance, to give you room to solder and move your hands around. plus it sounds as if the “specs” are chinese lumens, so to speak… resolution was different than expected, etc etc…

i can build a thoroughly ridiculous device, lol… it just might LOOK silly… but, if youwant “magnification” and “working distance” as requirements, thats not a hurdle… the vertical tube will just get taller, thats all…

=============================================

just wait a while, and i’ll mock-up a working device in the workshop… i’m in the middle of re-plumbing most of the house because of old man winter’s doing, lol… (my basement? looked like an ice skating rink, LMAO)

you would have to appreciate? i can put an image sensor on A-N-Y lens imaginable.

i can put them behind “real camera lenses”, or, i can use bare lenses laying around to fab with.

either one can be “video screen only” or, you can look down thru a microscope sort of tube, then clap on the video feed to look down thru the eyepiece…

I’m thinking “zoom in” “zoom out” would be by changing lenses, if it was not built around a camera zoom lens…

but, i’ll see how “nuts” I can get when i mock up with what i have laying around…

okay, i went back up this thread… to see “the guy that had the cool one”… that was a project on some other site.

he did similar to what i am talking about, except i have a couple OTHER ways to build the thing as well…

his “wow” photo at the end? is a 200mm lens… which is i suppose okay for date night in the barrio and all… but…

really now, this is BLF… we dont do “adequate”, do we? No, we start at “ridiculous!” and go on from there

i’m thinking 600mm lens for a start… i can go higher… lol… show you the inside of a fly’s @rsehole if you really want, with something like a 1200mm lens… like i said? i have basically no practical limitations on specs. building around a real camera lens introduces the limitations of the LENS, IE… how close it will image up…

when i use lens(es) and fab the “camera lens” up myself? the limitations no longer exist, as i can choose distance from lens to sensor at will.

I don’t think more focal length is what I want exactly. The resolution is better up close of course but it’s only a small field of view (obviously Facepalm it’s a microscope). Having the microscope back enough to work with a soldering iron gives a good field of view to me (displayed on my laptop). I guess I should plug it in and take a picture to give you an idea of what it’s like.

I’m having issues signing in to google at the moment so I uploaded the pics to imgur

These ones are about 30-35mm away from the driver. One of the pics I poked a 0.7mm bit of solder into the pic. The actual size of the pics is not much bigger than what you see here.


These next pics are about 90mm away from the work. One is the calibration ruler for the ‘Measurement’ program which I could not get to open on my pc.


This last pic is focussed on the plastic lens. It has even more zoom after that which is useless.

As you can see a decent clear lens would go a long way to helping

I just whipped this together, and i was bummed i couldnt find the lens i was LOOKING for, so i “settled” for this one…

this is the YEAR on a united states penny… working height? Uhm… i can stand a 2-liter bottle of mountain dew upright under it on the work table, lol…

 photo Picture 001_zpsbonfjpcg.jpg

this is nothing, i could easily get WAY more magnification, and WAY more working height, too… actually this is a little ridiculous, if i were using it to solder a driver component? I’d have to jack up the working height another FOOT i think, ha ha.

if this is going to be a competition? i plan on winning it, hee hee… i was given specs to push…

1) “more magnification”
2) “more working height”

I think i already exceeded those, and this is the “wimpy” set up… i could get “mid-evil” from this point out, this is just the starting point… I mean, when i said i could show you “up a fly’s arsehole” ?? that wasnt a JOKE…

my mock-up unit, is shaped more or less just like your commercial one… its a tube device, suspended over the work area. Right now, i am just using a c-clamp to hold my tube at about 12” or so above the table. Obviously for the final build, i will make a sliding clamp to adjust height.

my focusing is a push-pull though, one tube sliding in and out of the other. “zoom” in or out is accomplished by raising and lowering the work height. On MINE, I am actually zoomed in “too much” and i still have a FOOT of work height, in practical use, i would probably give myself even MORE work height, simply to lower the magnification a little bit to make it more reasonable.

well… this is a flashlight site. (i know, “duh”)

but, if i try to divide flashaholics into stages? I’m no longer a rank noob, but, i’m also far from being any expert. I’m in that “awkward” middle area.

but… when suddenly “USB digital microscope” appeared? Well, yeah i got very excited! just like a little kid! Why? simple… you wandered into MY WORLD. I might not be like “old lumens” (rip) with visible flashlights? But… I’m a lot more comfortable and “powerful” when i am doing digital imaging.

just like YOU guys cant believe what people are willing to pay retail for, and get so little out of flashlights? I cant believe what passes for a “USB digital microscope”. For the same money? I can CRUSH that unit, i think.

i am resisting “temptation” of lowering the working height DOWN from 12 inches, to 30mm… which seems to be about where most projects and commercial units give their “wow” images… at 12 inches, i already have the “2015” more than filling up the entire screen on the laptop viewing of the webcam image board, and am idly curious how small my field of view would become at that work height.

I’m kinda curious when i use the “big lens” how much more magnification i can GET, although i know its only academic… i already have magnification higher than i would want to solder at.

I am also kinda curious, if the money you spent on the commercial unit… was put only “where it counts” in a project build, how it would end up. I mean, lets face it… the work space is nothing, the imaging tube is just a tube and some sliding clamp or gooseneck to suspend it over the work area… the only things that REALLY matter, are the LENS and the IMAGE board.

but yeah, i get excited like a little kid, sometimes. I enjoy a project.

With enough black coffee and cigarettes? all things are possible…

Also excited. I’ve been having severe envy of the magnifying binocs my dentist uses.
And the little wand camera they can put into my mouth and take pictures of individual teeth.

Waiting for someone to specify an ideal setup I can buy, for soldering.

Now, if there were shake-removing “waldo” devices, I’d be gratified.

Well? after i get a shower and a change of work clothes? I might see about a few more pictures, zoomed in and out on a real driver board… I need to change the focusing tube setup for a longer range of focus, too. I wonder how much more magnification i can get out of this lens without trying a different one…
