I think non native English speakers are using the AI bots for translation. The results are easy to detect due to the very formal and detailed with proper grammar reply not usually seen in traditional human created posts.

Too correct, means AI or Vulcan.

Based in that standard I propose that @Ya’akov is an AI or Vulcan.

Only a Vulcan (those special eyes) can make pictures like that.


So , at least a human hybrid.

 

Why would you put two LM317s in series?

Even using one is going to be problematic, since the recommended minimum dropout is 3 V, which means you may not be able to get more than 2 V out with a 5 V supply. You can 'probably' get 2.4 V out, since parts are almost always capable of operating a bit outside their specs, but it is very poor design to rely on that.

To provide current regulation as well as voltage regulation. The idea was originally suggested to me by Dick Cappels as a way to add current regulation to a LM317/337 Dual Power Supply. It does the job with the caveat of 6V headroom so I was intrigued when I seen crutchow combine the circuits for a 5V supply.

 

I agree and am not sure why it is designed that way. It is a w00044 transformer with no other electronics involved so those batteries get 2.4v 24/7. Maybe to be kind to the batteries?

At least, a diode bridge or a single diode is to be involved.
There's any data on the transformer housing? Secondary voltage /amperage?

I suspect it is like many cheap chargers for NiCd power tools, a transformer, diode, and resistor. They usually supply too much current, causing early demise of the battery. Designed to sell you a new battery every year.

 

For the record, DX Engineering—the venerable ham radio dealer—sells spares for the ISO-TIP, and not at eBay “vintage” prices.
