Re: OFF-TOPIC: Jeeps, shifting, and snow (was: Batteries)
At my last job the tractor of a tractor trailer was blocking our loading dock. The driver got into an argement with his dispatcher, left the keys on the seat and stomped off in a huff. No one but me

My truck is also non-synchronous, double clutching is absolutely required. It becomes second nature once you grab ahold of the floor shifter. Dan On Wednesday, March 5, 2025 at 12:20:53 PM EST,

OFF-TOPIC: Jeeps, shifting, and snow (was: Batteries)
No, I traded it to a WWII reenactor. My father bought the jeep new surplus in 1949. The state decided the original bill of sale was OK for licensing. The jeep ran fine in 1975 when Dad realized he

Re: Batteries
I know what you mean and agree it would be better if a non-standard size. On a practical basis, if someone is paying $20-30 for a battery, it is not left on the kitchen table. These batteries

I get that. But the problem is they are selling them in the AA, C, and D form-factors, where the expected voltage is 1.5 V, not 3.6 V.? That is a catastrophe waiting to happen. Andy

Re: Slew rate and BW logic when designing differentietor of a pulse
From the datasheet and a few calculations. Your simulation uses +/- 7.5 V power.? Let's assume the output can approach (not reach) the rails.? The output pin sees R2 = 200 ohms to a virtual

Do you still have the Jeep? I restored a 1939 Plymouth Pickup truck and would love to restore a Jeep. Dan Kahn Newfoundland PA On Tuesday, March 4, 2025 at 03:39:56 PM EST, wn4isx via groups.io

Re: Wireless Camera repair
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.

Re: Slew rate and BW logic when designing differentietor of a pulse
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
OFF-TOPIC: Jeeps, shifting, and snow (was: Batteries)
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

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

Re: IR digital cameras (was: Batteries)
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

Re: Slew rate and BW logic when designing differentietor of a pulse
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
