The
QX3 Intel Play
Computer Microscope

First impressions by

Intel, the computer chip makers, and Mattel, the toy designer, have in partnership designed a very educational toy, to teach optics, imaging and computers. This is a high technology enterprise, and it takes a fairly good computer to use it. Windows 98 with support of the USB port is essential, a fast processor surely helps.

The magnifications are 10X, 60X and 200X; there is no eyepiece, all the imaging is on the computer screen, and the power for the whole thing comes from the USB port. No batteries to buy!!

A green LED is in the top on the circuit board, and it lights up, as soon as it has a connection to the computer, so one knows the connection is OK.

The software comes on a CD-ROM, and it really is outstanding in its functionality, it is very easy to install, and looks very nice, with a lot of sound, yes, this is not a quiet microscope. Even the help is sound only. The only thing I miss is a minimizing button, so I can look elsewhere for pictures etc., I always have to shut the program down, there is supposed to be one in the timelapse mode, I have not really tried that.

It is very easy to take snapshots of the image in the main viewing screen, or make movies and take timelapse photomicrographs in intervals of 1 sec to 1 hour.

The objective turret rotates very positively and smoothly and has a stainless steel ball to stop it precisely. The working distance is quite good at about 25 - 28 mm. The objectives are protected by a clear polycarbonate cover, that is mounted with screws, this cover is easily scratched, but replaceable. It is possible to obtain spares from Mattel, and it's probably a good idea to have some on hand along with extra light bulbs.

The microscope is designed with 2 light sources, one for reflected and one for transmitted light.

The reflected light source is under the protective lens cover; when the body is lifted off the stand, in order to use the microscope in a portable manner (to the length of the cable) the light goes with it. The stand with its stage has electrical contacts to control the transmitted lightsource. All the controls are on screen, but in the portable mode there is a button on the top that can be used to take snapshots or movies and timelapse, if it is kept depressed. The big focusing knobs work smoothly, I never had any problems with them jerking.

I made a small auxiliary lamp with a variable resistor incorporated, that helps a lot to get different light on the subjects. This can be seen in the picture of the whole setup (right). I get better colors with my aux. lamp, and it is of course much more flexible. I want to try laser light and fluorescent light in the future.

Additional notes:

Images of the microscope were taken on my Olympus D-450 zoom digital camera.

A minimum requirement of a 200 MHz Pentium processor with 32 MB Ram and a 800 X 600 pixel display with 16-bit color depth, that are 65,536 colors is asked for by Intel, [but this would be very minimal, and make the actual image coming from the microscope very jumpy].

I have a 500 MHZ processor, 64 MB Ram and 32-bit color depth with an 800 X 600 display. That works very well. I have not tried to take any video as yet.

 

Editor's note: The makers stated magnifications 10X, 60X and 200X are based on the images being displayed on a 15 inch monitor; the primary magnifications of the QX3's objectives will be a lot less.

Editor's update Dec. 2004: The updated model, the QX5 made by Digital Blue, is reviewed in the Dec. 2004 issue.

These yellow flowers are growing wild on a bush, that blooms all year long, It is close by the house. This picture was taken with the auxiliary lamp as a light source only.


Flower pollen 200X. This bush grows down town by one of my customers office.


Baby fly, 2mm long shows up quite nicely at 200X.


Parakeet, small feather
from the head 10X.


Chile Piquin 10X.

These chiles grow around my yard; if you should ever bite into one OH OH, one would be very sorry, but they make wonderful salsa, with tomatoes etc. Most people like these for their good flavor, and they are supposed to be the healthiest chile to eat. The mockingbirds eat them off the bush, and that is why the are growing in so many places.

 


Leafcutter ant (10X). They are a pest here, they will strip a small tree of all its leaves in one night, and they always look for my best plants in the yard.


Head of leafcutter ant (60X).


Leafcutter ant eye (200X).


This Grasspur is a bad weed all over South Texas. These stickers are very sharp and are hard to pick out of your clothes mostly the socks. When one is in your skin, it hurts quite a bit! This is at 10X.


Grasspsur at 60X shows attractive detail.


You can see the little hooks on the end of these stickers at 200X, that is why they don't come out of the skin, and hurt so much.

Resident of the yellow flower above.


At 200X this little resident is on top of the pollen in the yellow flower.


Here is the brother (or sister) on the pollen. It must be his sister, because she looks more shy. 200X

Ex-resident of the flower of the Granada Bush, photographed as he was leaving on the black cloth, that I put on to the stage. This covered up the opaque diffusion screen of the lower light in the stage of the microscope.
