Today I received my latest order from Prusa, a TPU filament from ColorFabb along with some bronze inserts for 3D print assembly. Extremely fast shipment by DHL, the package arrived in only one day. Next days I will print some belts for a device that I have and will publish the results and my impressions. […]
A timelapse of Fusion360 design of the case of the 101dB attenuator project.
I made some progress on my antenna rotator project and installed the stepper drivers and the Raspberry Pi computer. I bought two drivers from ardushop.ro and these should work just fine. They are based on Toshiba TB6560AHQ, PWM Chopper-Type Bipolar Driver IC for Stepping Motor Control. The datasheet can be downloaded from here. My projects […]
I needed this 3D design for a mini N connector that I have in my shack but I was unable to find any 3d file (.STEP etc) online. The connectors are used for my 101dB attenuator project. Enjoy ! Greetings.
My 3D printed antenna rotator project for ham radio satellites. Status 09/16/2021
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.
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.
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 […]
