I had Logitech C930e webcam laying in my drawer for a while waiting for a better fate. So today finally fitted it into aluminium C920 enclosure to be used with CS lenses. Actually it did not took much, had to remove some material on my trusty Proxxon MF 70 mini mill, everything else fitted like […]
Read MoreIt takes two Raspberries to run a clock
Despite lousy title, I will tell my success story how to add visual output to well known IoT tool called Node-RED. One Raspberry Pi, let’s call it RPI-RED, will be running Node-RED another one RPI-LED will be dedicated to server LED panel. First you should should install Node-RED to RPI-RED. Installation is well described in […]
Read MoreNode-RED for rapid hardware wiring
I will be posting few interesting follow-up posts that are based on tool for wiring together hardware devices called Node-RED. This post will serve as a reference how to prepare Raspberry Pi and install dependencies. Besides usual IoT stuff (sensor serving, data collection, aggregation and decision making) I see great opportunity to use node-red in rapid […]

Finally received firmware configuration tool from Sonix. This enables control over various hidden firmware parameters like denoise, bayer filter, edge enhancement, resolution table, lens shading, dealiasing and many more. While most of these parameters normally should not be touched on general functionality others makes huge sense. Added serial number I can now embed unique serial […]

I rarely publish my fails in manufacturing, but this time I’d like to share that only two minor mistakes were made. One of them was finish type. It ought to be sandblasted before anodizing process unfortunately this […]
Read MoreHeatmap motion analysis of autonomous robot
I have always wanted to ease my daily life and obtain vacuum robot. Many things were stopping for a while, but finally found a local company which provides demo units so could not resist taking one for a spin. What a good chance to run some computer vision processing algorithms to analyze it! Seen few […]
Read MoreNew Raspberry Pi enclosure
This is short announcement about changed Raspberry Pi enclosure revision. Revision was changed from revC to revF. Now it is slimmer, more secure and redesigned for Raspberry Pi 3 in mind while maintaining compatibility with previous versions. Also note few missing revisions – these were custom made ones I can’t publish. What’s the difference? […]
Read MoreDon’t look at laser with remaining eye
Laser is a great technological invention. One of it’s use case is to make markings on an solid object – aluminum enclosure in my case. Sandblasted and black anodized coating reveals gray material underneath. This marking is fast to apply, durable and looks awesome. First product I will be marking is Kurokesu C1 USB camera. […]
Read MoreDo you want to see the unseen?
I have always been fascinated by Infrared photography. But it was associated with big cameras and complicated rework process. Never considered using small cameras for this task until yesterday. After taking videos for new experiment (count bypassing vehicles) I switched to modified camera and captured short video of surroundings. Was surprised that camera worked flawlessly […]
