Wiki has an interesting page on submiature RF connectors.... https://en.wikipedia.org/wiki/Hirose_U.FL I had no idea there were so many connectors that look very similar.

Hello Andy , regarding the 200Ohm load,How did you? see that I am over loading the opamp? Could you say what measurement needs to be done and where in the datasheet I need to look for this issue to

In our case it was me who decided "Dear God I've got to downsize!" I had about 30X30X20 in the corner of a warehouse filled with 'stuff.' I even had a WWII era jeep. That was a nightmare to license

That's one heck of a temperature range, there... And a 40 year lifespan? Wow. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of

Andy, When that type of performance is needed, it is a custom design project and not for the general public. I do not expect the batteries will be replaced in my lifetime. When the equipment is

Some Panasonic digital cameras are fairly easy to modify. You remove the IR blocking filter from the CCD camera. With this mod you'll get a mix of visible light and IR, I still had the IR passive lens

Agreed. Be aware that you are also over-stressing the op-amp with the 200 ohm load.? That's 37.5 mA peak output, which it might not provide.? But I think that is unrelated to the question. Andy

I wonder if that's true of all of them.? It probably is.? Photons are photons.? I know my first digital almost-SLR from 20+ years ago could, and I considered having the modification done to it.? I

Darn!? All these alternate technologies!? With built-in ways to mess us up. Those Tadiran cells come in standard AA, C, and D form factors, but do NOT have the standard voltage.? Their nominal

For the ultimate lithium battery (cell) see: https://tadiranbat.com/products/long-life-xol-series-batteries/ The Tadarian battery operating temperature is -80°C to +125°C and 40 year life. We

Well, that is far more response than I expected! Many thanks. (My spouse won't let me bring any more technology bits into the house until I clear out "all that stuff you've got here!") Donald.

I've ordered a set of 4 AA cells to see how they work. Now these cells clearly have a circuit for charging and to step the 3.6ishV down to 1.5V. IF they perform as advertised, they would be an

Sorry for the ambiguity of the question - I was speaking of secondary cells, like https://paleblueearth.com/ offers. Donald.

I think we're probably just seeing the op-amp's overdrive recovery behaviour.

There were no electronic components in either the AA or 9 V. I've already taken them to the electronic recycle center or I'd post photos. It's been too many years since university, but, I may well

Hello , I have designed a differentiator as shown below.The pulse in the simulation photos links below is 1ns which is 350MHz BW ,much higher then the BW of the AD8034 opamp.As you can see its

I think they they added a resistor with a diode wired backwards to the main diode that diode provided V+ They specified a 10% reverse charge Say you charge at 100mA, then you'd want to add a reverse

Wiki has an interesting article on lithium batteries, the data is somewhat at odds with the information in the book. Lithium cells/batteries is an extremely complex subject with a lot of what appear

Just to be clear about this - I wasn't talking about Chinese brands.? I was referring to American battery brands, with off-shore manufacturing. I first heard the story at a ham radio convention,

Yeah. But the last ones I bought weren't anywhere near that expensive, maybe about $2 a battery? I use them in my camera.
