Gentlemen, what we need to do is develop a system whereby the electrical energy of the clouds is captured and safely transmitted to a storage device on the ground for later use.

Has the drone bug bit MicroRem? :smile:
They can be addictive! Only the imagination limits what one can do with a remote camera in 3D space.
I'm amazed that a large following of droners go long distance- out of sight, like several miles! Explore your neighborhood!

Anybody playing with these techy gadgets?
My DJI Phantom 2 Vision Plus uses 5.8 GHz for flight control, while sending back video on 2.4 GHz. Fairly fancy comm network!

Next big industry will be how to disable them in flight, if they pose a threat! :shock:

Looks like LR44's have 150 maHr rating- even less than the ProCell.
Two parallel banks of them (to make a 9 volt) would outlast the ProCell, but oh, the hassle. :razz:

Thanks guys-
Space is an issue in this application.
If not Duracell or Energizer, what is recommended for a better alkaline 9 volt? (Lithium disposables too expensive)

Been a big fan of Duracell for many years, but these are a disappointment. Just don't last as long in 50 mAmp application.
Going back to Energizers!
Anybody else have a review for this cell?

If you have access to a variable AC supply, ramp up the primary voltage while watching the secondary voltage to confirm the markings. Maybe a Variac? Even a lamp dimmer would give some idea of the markings veracity. Measure RMS in and RMS out.

Nice to hear from you again Mr. Al! I dug this old Craftsman DMM out to complement some Flukes I use regularly. Haven't used this old "Crapsman" for years. It has 4 buttons across the top: Power Range-H Beep/diode check Data-H What is Range-H for? I think Data-H holds the last (or highest?...

Thanks but there's something wrong with that ad. It actually leads to a Klein meter. No joy.

Looking for the operating manual for an old autoranging multimeter:
Craftsman Autoranging Multimeter 82028

Googled, but couldn't find it. It's maybe 15-18 years old.

TIA!
