Just remove any screws and plastic cover that is not needed.

can i make it without microscope and what type of microscope it is ??? i am from india i am not able to find one

You need a microscope for this. Try eBay - I've found a x1200 microscope for 25 pounds, free worldwide shipping

This is really neat but the title is a little deceiving, since the Microscope part of the USB Digital Microscope for only 15$ costs around $250. Otherwise, good job

Trust me - this microscope is the cheapest type you can buy in a $ shop (it cost 10$) - If I where to use a 250$ one the pictures would be much much better!
give it a try.

How to change magnification?
The microscope pictured has a revolving "turret" that allows the user to dial a magnification. You can see a similar microscope with the parts labeled at this web site: http://www.microscope-microscope.org/basic/microscope-parts.htm

In bold @ the top of step III it says "...add a red and white wire."

Should be red & black as I'm sure you know :p

 hey can you please give me materials how to build this microscope because i want to build two different kinds of microscopes?
how would you make it magnify in the thousands 1200x just wondering
On optical microscopes the maximum usable magnification is around 800X with out using oil immersion. If you use oil immersion it is possible to get a magnification around 1200X, but only under thebest conditions.

I assume it should work .. just give it a try and play with the distances before you put the glue. see the image in real time and only then put the glue on.

You can get better qaulity if you use a nicer digital camera (more detail with higher x) Plus using a stand allows for greater mobility and ensures you get the picture you want, check out my instructable) Sure it's more expensive, but it looks cooler. otherwise AWESOME INSTRUCTABLE (: (my I-able) http://www.instructables.com/id/How-to-take-crystal-clear-digital-snapshots-throug

lol Forget cutting myself, I've managed to solder myself once. =)
once I dropped my soldering iron.... then I caught it..... :P
(in case you didn't catch that, I mean I just caught it as a reflex and grabbed the business end.)

nice work, Do you know the magnification of the objective, eyepiece. Or you removed the eyepiece.
moris_zen (author)  ramuproject6 years ago
I didn't remove the eyepiece just glued it to it.

Where did you get the camera (webcam) from, or what is its design?
moris_zen (author)  skizzilini6 years ago
The where stoked up in a pile in a computer store .. It was just the cheapest brand available .. some Chinese unknown brand...
what's the effect of putting an ohm resistor near the lead??
moris_zen (author)  fortunecookie6 years ago
If you dont - the LED will burn (it limits the current)
that's why my eyes feels itchy after i used my microscope with an led light. tnx

very good job =)

one thing, its insulation, not isolation...
yeah but insulation does Isolate so I think that it could be called isolation.
... but that doesn't change the fact that the material around the wire is an insulator to electricity and used for that property. its confusing to call it isolation
Yeah I suppose that's true.

Thanks for repairing me English (just joking)
Great job Dude!! I was looking into buying a USB Scope and the problem was the 20X to 200X limitation before they got to be too expensive, I will definately give this a try.

In step 3 when you cut the red and black wire. Do you connect the two halves back together along with the extension?
