My 3D printed antenna rotator project for ham radio satellites. Status 09/16/2021
Project status – 3D printed antenna rotator (12/09/2021)
This is a short video about the progress of my 3D printed antenna rotator. Unfortunately only in romanian for now, but captions will be created soon.
Kicad & Autodesk Fusion 360
I published on YouTube a video about how to export ecad files in KiCad and import them in Autodesk Fusion 360 to create nice electromechanical assemblies. Captions in english.
Short Assembly test in Fusion 360: RoLink + Raspberry
A very short clip with assembly test in Autodesk Fusion360: Raspberry Pi and a hat I designed for mobile radio. This type of simulation is extremely useful to pin point issues in mechanical design and assemblies (see at 0:35), that can be avoided early in the manufacturing process. I will create a more detailed tutorial …
My friend YO3IJ and his new IC-705
A very short video with my friend Erim Soyhan YO3IJ/TA2IJ and his brand new Icom IC-705. Partly in romanian. There are captions in english for sections in romanian.
Tuzla 2020, Field day
I published on my YouTube channel a video about the ham radio Field Day event at Tuzla, Romania, 2020.
KiCad Templates for Orange Pi Zero
KiCad templates for two different hat models for Orange Pi Zero boards can be downloaded from my GitHub repo. Two different KiCad templates can be downloaded in the same GitHub archive: one uncut, 46×48 mm exactly same size as Orange Pi Zero; the other one has some cuts for network and USB connector, to accomodate …
LTSpice simulation of Baofeng UV5R band selector
I was quite busy the other day trying to understand how Baofeng is using RDA1846 transceiver in their products. While analyzing the schematic it struck me the overcomplicated way they do the switch between UHF and VHF. This is an excerpt of the schematic: The entire selector block is made up with discrete components ! …
Jabra Evolve 65 repair
A couple of weeks ago during what should have been a routine firmware upgrade, my Jabra Evolve 65 simply died. Have no idea what happened and maybe that will make an interesting future project, but because this headphone is my main headset used for teleconferences and other communication required by my job, I was kind …
