New ideas every day
This post together with previous antenna related posts is a introduction to a open-source library of wide-band general purpose antennas that I m planning to create. I will share all information s about the design process together with detailed electromagnetic simulations results, measurements and assembly instructions so… Continue reading The post PCB Log Periodic Antenna (0.8-6 GHz) appeared…
In this post I will show you a very simple Balun PCB (TCM2-63WX+) with a transformer that converts single ended signals to differential signals. Baluns are very useful for many measurements and RF projects. RF engineering can quickly get very expensive (especially when you go… Continue reading The post Balun PCB (50Ω SE to 100Ω DIFF, 30 to 6000 MHz, TCM2-63WX+) appeared first on ByTechLab .
Recently I have started a phased array FMCW radar project. I needed good antennas for this purpose but I haven t decided which frequency to use yet. That s why I have decided to choose a wideband antenna I will be able to switch between different… Continue reading The post 3D Printed Double Ridged Horn Antenna (2-6 GHz) appeared first on ByTechLab .
In this short post I will show you a very useful accessory Rigol DL3021A 4mm Banana Jack Adapter. The stock configuration of the Rigol DL3021A uses screw terminals which are quite painful to use and are not compatible with 4mm banana plugs of course.… Continue reading The post Rigol DL3021A 4mm Banana Jack Adapter appeared first on ByTechLab .
Recently I have built a Bambu Lab X1C Fume Filtering System which is based on Xiaomi air purifier (link) . It came out that this air purifier works perfectly there s zero smell PM2.5 sensor shows the value of 0 (when printing with ABS… Continue reading The post DIY Soldering Fume Extractor (air purifier based) appeared first on ByTechLab .
The filter that came with the Bambu Lab X1C 3D printer is not great to be honest it looks like it is not working at all. Recently I had to print many parts with ABS. The fumes generated from ABS smell horrible are… Continue reading The post Bambu Lab X1C Fume Filtering System appeared first on ByTechLab .
Recently I ve noticed that the time seems to be running away from me very quickly. Nowadays we live in such a hurry that it s hard to keep up how much time is gone and how much time we have left. It s easier for me to… Continue reading The post LED Calendar (ESP8266 based) appeared first on ByTechLab .
