DigiMicro 200X Zooming USB Digital Microscope in ubuntu (linux)
I’ve wanted a USB microscope for a long time, and I have finally purchased a DigiMicro 200X Zooming USB Digital Microscope from dealextreme (product link) It only cost $40.23 USD (about £27.34 GBP) which I think is quite reasnoble for the fun and cool photos I’m getting out of it.
- Very Cheap
- Easy to setup (plug and play)
- Can take some awesome photos, see below
- Three illumination settings (full on, half on, off) on top of software compensation
- Controls (lights, zoom/focus and snapshot) are located on the body which make using them difficult if you are trying not to move your sample
- The stand is not very stable, tightening it to maximum holds it steady at certain angles for short periods of time
- Takes ~ 2 weeks to arrive from dealextreme as they are based in hong kong
The beauty of this webcam is that it requires no installation with ubuntu 9.10 you simply need to run the software and the camera works! woo! The output of `lsusb` shows the device as:
Bus 001 Device 006: ID 0c45:62e0 Microdia MSI Starcam Racer
and `dmesg` shows the following:
[22844.064666] uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62e0) [22844.080844] input: USB 2.0 Camera as /devices/pci0000:00/0000:00:0b.1/usb1/1-6/1-6:1.0/input/input9
Most video programs will pick up the device, I am opting to use a program called cheese which is awesome not only because of the name but also because of its simplicity.
sudo apt-get install cheese
Remember to take the lens cap off otherwise you will end up focusing on the plastic cap as shown below. It is fairly obvious if this is the problem as moving the microscope will only change the light levels not the image.
Any requests for microscope images (within reason) will be considered
