Step 5: take some pics!

so, now take some pics.. i took a few pics of things you might have arounds so you can get a sense of how much things get magnified..

one really neat thing i had around was a piece of core memory from an old CDC-6600 machine (classic machine nuts can begin going crazy now)

so below you can see a broad picture of the board, and the other picture which is a close up of the torriod and wire mesh that make up the memory cells

since the camera is a 2 megapixel camera its got pretty good resolution, the software logitech makes for it seems like it was made for the job. and the zeis lens has an electromechanical focus that seems to adjust to the bizarre focal length we have here.
nice job. where did you get core memory? it's awesome...
got it from the secret place where old super computers go to die.. warning: this will make you sad http://www.stonedcoder.org/~phar/cdc6600/
I have a 12MP camera with a built in battery that died, it also doubled as a web cam, would make a great USB Microsope.. :) Just have to figure out how to get it to work without a battery or with a new power source.
You should be able to usethe optical sensor but if i were you id try building a power supply. Just the right bridge rectifier could do it (dangerously). A wallmart (scavenged plugin power supply) and a rectifier should do it. I never throw away a power supply anymore.
Don't try that! The built in battery is max 5V but a plugin power supply can give out from 5-24V AC/DC, and the bridge rectifier is not enough you also need a big cap, to stabilize the voltage, after that you should put a voltage regulator like 78m05 for 5 volts etc.<br />
<p>... internal battery? is it just a lithium poly that wont charge? if so its easy enough to replace the battery yourself, you'll need to check the battery package to verify&nbsp;its a 3.7v &quot;single cell&quot;<br /> <br /> digikey/mouser will have a LiPo battery that will fit where the old one did, just be sure that the &quot;mAh&quot; (amp hours) rating matches up so that you get the same battery life.. getting greedy and getting more mAh's may work, or you may get a battery too thick to fit back into the case.<br /> <br /> and if you just wanted to hardwire it for webcam use, i would recommend a 3.3v )&nbsp;regulator fead from the USB +VBUS signal, i should be fine up to ~150mA<br /> &nbsp;<br /> .. i know its&nbsp;a rant, but im bored!<br /> &nbsp;</p>
not being picky just clarifying for other readers... Walmart = Wall Wart = big old hunk of ac/dc converter that sticks out of the wall plug like a &quot;wart&quot;<br/>
Would this work for the 30 AWG&nbsp;wire?<br /> <a href="http://www.amazon.com/Wire-Roll-Insulated-Kynar-Blue/dp/B000PDO1B6/ref=sr_1_1?ie=UTF8&amp;s=hi&amp;qid=1258233817&amp;sr=8-1" rel="nofollow">www.amazon.com/Wire-Roll-Insulated-Kynar-Blue/dp/B000PDO1B6/ref=sr_1_1</a><br /> <br /> And if i understand, attach the 2 30&nbsp;AWG wires to each end of the LED, and reroute them to where the orange LED&nbsp;was, and put the wires in place with hotglue?<br />
Is there a way to make this microscope working with mac?<br />
<p>it all depends on the webcam itself, afiak all logitech webcams work in OSX<br /> &nbsp;</p>
Thank You. I'll try.<br />
I have a logitech webcam and unfortunately all I can see is a image of a inside lens of the microscope. When I use only the microscope I have a good image and when I also use the webcam I can focus it to get a very good image. But together they don't work. Is it something that I miss? Please, give me an idea since I desperately need to take pictures with an webcam and the radioshack microscope seems to give a good magnification for my project.
Nice job. this is a great project. I've used an old microscope objective with my quickcam 4K a few times by taping the lens body onto the camera body, but nothing quite as permanent or quite as effective. I like the light...
Awesome, honestly. This is the best thing to come out of Radio Shack in years.
I like the scope. I used to get a catalog from Radio Shack to find out what they discontinued. Now they discontinued the catalog.
Interesting project. I was a Customer Engineer and worked on Control Data 6600s in the company data center in Houston in the late 60s and 70s. Replacing these memory stacks was a regular procedure. the machine was 60 bits wide with NO parity check.
Well done project. Nice way to get the image into a computer for storage or processing. I too, was a service engineer, late 70's to early 00's, and in the early 90s I was servicing two Honeywell H716s at a location in Japan. They were the last two such CPUs with core memories in use in the world and had two 4K cores, 12 bits wide, and a wire-wrapped card-cage with 10 CPU cards. The things were octal coded and required a fat-finger routine to get the paper tape to load...
wow, put the coffee cup down and step away from the table. on a nice note, the scope looks like it would come in handy for those pesky SMD fixes It would be helpful it was smaller. all in all a neat cheap design. I used a pocket loop 10x about $5 from e-bay and a older logitch camera and came up with something smiler but it was a real pain to keep the focus correct.
Impressive quality image from some off the shelf hardware and a good measure of ingenuity. Nice work!
Where did you get the magnetic ring core memory? Classic stuff!
Wow how did you open up your CPU?! Btw nice project!
Wow... at first I was reading USB "microphone"... and it stayed that way for a good 3 minutes. "What the hell.. this looks more like a micro... OH!!!" anyway, good job. What magnification is this more/less equivalent to?
60x to 100x maggnification. i have the same microscope, only smaller because it uses watch batteries.
lol same here
I did the same thing. I saw it on the front page a few times and kept thinking "but those have got to be cheap to buy..." And then I saw the bit where he had said he had bought a camera. That really should have cleared it up for me, but it really just confused me more. That's when I opened it up and ..."OH!!!"
the microscope itself says 60x - 100x but without printing some sort of scale and viewing it under magnification i couldnt tell you exactly.. the webcam itself has some quantity of optical zoom as well.
Hey Ribs i live in Cape town and have the same problem. i dont know if you have experilab in joburg... that shop has things similar to these, although they dont have any hi tech stuff, so try www.bidorbuy.com or just cash converters.
i used to buy all my stuff at experilab when i was younger but like you said their stuff is a bit low tech and they dont have much variety...... its lekker to see some SA locals around... cheers man
Does anyone know of a South African equivalent to Radioshack? I am in Jo'burg.
in jo burg you might find a place specifically dealing in products like radio shack has but usually one has to go to an electrics shop to buy electrical components.......problem is most electrics shops are privately owned and are not franchises like lets say McDonalds......so you need to find one in your area.....or hack old toys, appliances etc for components that can be desoldered hope it helps... cheers
for people having a hard time finding the microscope, and for those that want to *attempt* higher magnification, i just noticed edmund scientific (even more of a dinosaur then radioshack i suppose) has a selection of inexpensive &quot;pocket microscopes&quot;<br/><br/>shop for something with a light or you will need an external light source, cheap CCD cameras arent very good in dim light.<br/>
Oooof. A quality idea. Now I can scope my buds in even more detail.
most excellent, thanks for sharing!
I have to agree with bofthem, this is awesome! RadioShack has a lot of items in their cubby things but this is amazing! I might try this with my friend, we'll see.
