It has been a while since zoom lens controller v1 was discontinued. The reason was very simple and happens to the best of us – the manufacturer made critical part outdated. Half a year ago swept all available stock and manufactured the last batch. An updated version was in development, but only internal use sample […]
Read MoreUse of Kurokesu C1 family cameras in NIR spectrum
Usually, an image sensor is more sensitive to near-infrared (NIR) than visible light. For normal home use operation, it is mostly preferred to have NIR spectrum part to be blocked, but for scientific, industrial or biometric applications there are a lot of cases where having unrestricted sensitivity to full spectrum is a huge benefit. Kurokesu […]
Read MoreHow to capture 30fps with Kurokesu cameras in David-3D
When talk comes about 3D scanning everybody knows David-3D software. It’s a pity but it lacks trivial camera control options like selecting MJPEG mode and stuck in YUYV uncompressed mode, this limits performance to low frame rate (about 5 fps). David-3D software does not like it and refuses to scan. It was an issue and […]
Read MoreIntroducing C1 MICRO USB camera
Tiny and lightweight camera system based on original C1 was in development for a while. It was challenging to squeeze all components even to 6 layer PCB with tight tolerances. After a few design iterations finally, C1 MICRO M12 camera is released and pre-orders are open. Key features Lightweight and small. Camera weight without a […]
Read MoreNew cameras and near future plans
As new amazing cameras are in development and few will be released soon there was a struggle how to name them. Wanted to reflect it’s purpose and have universal coding so there was a big toss between few ideas and finally the decision was made. Kurokesu started camera portfolio with C1 camera in 2014. After […]
Read MoreWhich USB to COM port is the most recent one?
How many times did you find yourself looking for Windows Control Panel and wondering which is the most recent plugged USB to SERIAL com port? Well simple and clean Python script comes very handy for this task. Just start a script and plug in new device – new com port will be displayed with minimal […]
Read MorePedestrian detection using YOLOv3
Owning a quality camera can be fairly useful by itself. Video stream can provide a lot of information not easily comprehendable by just using various sensors. However, not always there is a human eye to make a sense of it. Therefore, additional algorithms can be implemented to provide a lot of insights automatically. A lot […]
Read MoreAccurately measure height with microscope
As the subject implies this post describes a way to measure the height of an object using the motorized microscope. The whole trick is to take many incremental pictures of an object (and background as a reference) from different heights and analyze how sharp each frame is. Some interesting hardware is needed, but nothing that […]
Read MoreSecond life for x18 motorized lens
Had this 18x (5.4-96mm focal distance) salvaged zoom lens in my “inbox” for a while. Finally made it “tick” again with C1 camera and motorized lens controller. Replacing imager was a matter of unscrewing old one and screwing on C1 PCB – mounting hole spacing matched. And talking of controller – it was not even […]
Read MoreBig scary laser
Or not. I have been begging Santa for fiber laser for years and this year seems like I behaved myself good enough to deserve it. Crate weight was more than 60kg, pulled my back while carrying it but I don’t complain. Marking It’s quite opposite to 3D printers where material is being deposited. Laser energy […]
