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 #testgeartuesday and I’m demonstrating the dipole near field with field strength meter in the local #hamr 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 #testgeartuesday , 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 🙂🔥☀️ #electronicsengineering #testandmeasurement #solarpower #solarenergy #ourlocalstar #astronomy
It’s #testgeartuesday and here’s a nice #lifehack in the lab, if you’re the happy owner of a #rohdeschwarz 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 😂👌🏻 #electronics
Yesterday was #testgeartuesday 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 #hamradio #eevblog #electronics
It’s #testgeartuesday and conveniently enough, I just received a pulse generator from #leobodnard 😃It has a risetime below 40ps (pico seconds, 10E-12)
Measurements will follow tomorrow, stay tuned for #waveformwednesday
#testgeartuesday Testing another scavenged (free’d ofc 🙂) infrared #laserdiode with a power meter. Quite powerful, it produces about 50mW invisible light 🙂 My camera sees it just fine 👌🏻 #electronics #electronics engineering #testandmeasurement #stem #physics
Søren Kjærsgaard Glen Beer Oops!😀 I used #testequipmenttuesday vs. #testgeartuesday but it played out ok…
Søren Kjærsgaard Andy It appears the last time #testgeartuesday was used was 2018. Since we probably already test gear/equipment addiction, it's a winner day.
