Came across this stash the other day, was told: grab what you want before it goes .. 😳🤷🏼‍♂️🤯
RF absorber panels like these are expensive and hard to get at as a private person, so I filled my little car 😂

It’s and I’m demonstrating the dipole near field with field strength meter in the local adio club - a fun and easy, and all-time classic, antenna fundamentals experiment 👍🏼😎

Cheap BNC high-power attenuators, 3 and 6dB, found them flat to 1GHz, which is way above the area of my application.

So what’s going on? 🤷🏼‍♂️☺️ Stay tuned, hints are in the tags 👌🏻

Yesterday was , here’s my ‘Pyranometer’ I got at a VERY reasonable price. I let the DMM do the math, so although it says ‘V’, I’m measuring 700W/m^2 in my window 🙂🔥☀️

It’s and here’s a nice in the lab, if you’re the happy owner of a 2CH oscilloscope: get some dust caps and seal the EXT TRIG input, so you don’t mistake it for the CH1 input. Saves a lot of frustration at the bench 😂👌🏻

Yesterday was and I was testing this beautiful vintage analogue DMM, likely dated 70-80’s. Came across my path a week back, had to bring it home, call it a rescue mission ☺️ Works fine still and it’s quite accurate

It’s and conveniently enough, I just received a pulse generator from 😃It has a risetime below 40ps (pico seconds, 10E-12)
Measurements will follow tomorrow, stay tuned for

Testing another scavenged (free’d ofc 🙂) infrared with a power meter. Quite powerful, it produces about 50mW invisible light 🙂 My camera sees it just fine 👌🏻 engineering
