There are quite a lot of inexpensive and fairly reliable PCB manufacturers that can produce double-sided PCB’s with solder-mask and silkscreen in a day or two, but what if you need it now? I will not cover expensive prototyping machinery nor messy printer/etching process instead let’s use a 20W Fiber laser. Because… who does not […]
Read MoreC2 family cameras
C1 family cameras have been a great success with installations around the world (eyes for underwater and flying drones, scientific process observation flying 408km above the Earth on ISS in a low gravity environment, many universities doing computer vision researches, a few industrial environment installations, and many more) It is time to start introducing new […]
Read MoreManuals, instructions, and documentation has a new place
Kurokesu uses multiple places to store and announce information. The main place was a blog (the one you are reading at the moment), GitHub, and manually created documentation HTML pages. After content expanded it become harder to manage it without CMS, so finally created to a wiki-like page here. Some information will semi duplicated across multiple […]
Read MorePulling full resolution from a webcam with OpenCV (Windows)
OpenCV while being the most popular tool for a lot of machine vision applications it relies on a third party and some poorly maintained code. Capturing MJPEG compressed video from a UVC USB camera was always the case and it did not work or worked with some issues. This situation is especially bad for Windows OS. […]
Read MoreMeasure linear rail quality with camera and excel
No matter how precise and rigid your mechanical system is, it will always have some imperfections. These imperfections can be measured and described. If measurements show opposite it means your measurement tools are not precise enough or you are doing it wrong. There are a lot of expensive and highly specialized tools to measure every […]
Read MoreUVC camera exposure timing in OpenCV
USB cameras can have the exposure set to manual (cheaper ones have only full auto mode). It’s a pretty straight forward function in OpenCV, but insufficiently documented thus hard to find exact times and calculations. Also there are two major implementations for Linux and Windows. Linux – exposure times are set in units 1/s (all […]
Read MoreIntroducing 4 axis stepper controller module SCE2
Post stamp-sized 4 axis stepper motor controller system on module SCE2-M is designed to save space and speed up motion controller integration time for custom products. When paired with industry-standard open-source motion controller firmware it can be controller by g-code and drive whole small CNC machine without external components. SCE2 is second Kurokesu motion module […]
Read MoreIntroducing motion family platform
About A few months ago last RSA1 rotary stage parts in the warehouse were consumed and the decision not to extend its life was made. Instead, the whole family of new motion devices was designed. Heart of all – is the motion module used in the main controller. It is a small standalone stepper motor […]
Read MoreUpdated C1 PRO x18 motorized camera block
After intensive tests and feedback from actual installations motorized 18x zoom camera block gets some updated. From now on only this version will be shipped. Updated feature list: New mount plate More stable and secure mechanical design Occupies less space Added new M3 thread mounting features to mount plate FFC cable attached more securely and […]
Read MoreC920 rework kit updates
Recently updated C920 webcam version was released featuring new PCB. These changes introduced two unexpected issues: wiring is different and new PCB has mechanical interference with aluminium rework kit back plate. Test-point locations If you rework webcam by yourself, please use pin-out diagram as pictured below to solder wires. TP24 – VCC TP26 – USB […]
