I know, chances you read this are very odd. But never the less I'll try to reach you 🙂 The area in which very, very small currents and voltages and low-noise amplifiers are extremely important is everything about sleep. To be more specific, anything to get the electromagnetic waves of your brain (microvolts) to determine your stage of sleep has to be extremely low-noise. I've worked as a technician in sleep laboratories for 12 years and learned to read an EEG. "Sleep" is such a fascinating area and we just know a little bit of it. Rechtschaffen & Kales in the 1960s first tried to really scientifically use EEG to determine in what sleep stage you are (awake, REM, light sleep [stage 1-2] or deep sleep [stage 3-4])
I boutght a max4239asa+ at Digi. It is so small! -key (8-SOIC (0.154", 3.90mm Width)
Is it really possible to solder that by hand? There is about .9 mm gap between the pins.
Is this why I measure current as 200mA in the mA range and 300mA in the A range of my multimeter? Which measurement is correct?
does that connect with the uswitch?
😀😀😀

cool vid never new that ty
where can I buy the uCurrent ? I encountered many dead links.
This will never catch on 😆
Just FYI this is the shortest title of EEVBlog video, ever (second one is "Top Geek?")
Can you tell me where I can purchase this precision current adapter
Shipping to Europe ?

Hi, What is the size of the Jiffy box.? I need it to figure the image size in Photoshop. I found
Jiffy Box – Black – 83 x 54 x 31mm – Bulkhead – UB5
@cjmitz No, you can't "compensate" for burden voltage in the meter itself.
Hello Dave,
Can I use your uCurrent on my DSO to measure current?
If so what are the limitations?
If not, then what would you recommend for a guy on a budget?
Thanks1
It's now on my web site. Search for "ucurrent"
remove spaces, and add periods in the right places… or google "silicon chip magazine"… go there… search for "burden"

How can I find the Publication you wrote ?
