This will be another short post. I also made the GitHub repo public, but please be aware, current design is flawed. If you use it, you acknowledge that you use it on your own risk. Today I managed to build the revision 1.0 of this power sensor, not without some lessons learned. It was my …

My first finished KiCad project is a prototype of a RF Power meter with input attenuation built around an Analog Device AD8307. An excellent tutorial about log amps can be read in March 1999 edition of Analog Dialogue. KiCad PCB: And the 3D rendering of the same PCB: The next step will be PCB ordering, …

Some more days passed and some more finishing touches added to my MacSCPI app. It is entirely dependent on hooking the device via the USBTMC driver, but it works fine and is stable: I had some problems with buffer padding and the output it is still not 100% gibberish–free , but I assume I have to play with …

After some head banging, I finally managed to send SCPI commands from my Mac to my Agilent (Keysight) DSOX2002A. I’ve worked on this since december last year. Almost a year, but I did not spent a sustained amount of effort. I did it just during my free time. I still have a day job that …

I was looking for a RF power module for my APRS beacon project and stumbled upon RF Parts. They are somehow of a niche–oriented online electronic part retailers, specialised on RF and — it seems — mostly on Ham Radio RF parts. I placed my order for two Mitsubishi power RF MOSFET Amplifier Modules and the package …

More than a year ago I posted this. It was the beginning of this blog and the beginning of my personal space for hobbies and small DIY projects, a very crammed and tiny space that I have in my apartment. I cannot imagine how quickly time passed and how less and less available time I have for …
