The Russian guy who wrote the EBookDroid app provides excellent customer
service for an absolute pittance. We asked him how we could pay more
(apparently paypal doesn't work in Russia), but he said just buy the
'pro' app. He also speaks (or at least writes) excellent English, such
that I wonder if he's just pretending to be Russian.

I think a lot of the Russian hype is a smokescreen. A lot of the really
evil stuff comes from a small middle eastern country Trump seems to love.

Saudi Arabia? A lot of US presidents have seemed to love them which is
surprising given just how horrible they are. Not exactly a role-model.

Not love them so much as realise that they arent as bad as some of the
others in the middle east.
 
Same with Jordan.

Sure, but certainly not as bad as the worst of the rest.

I got a grab bag of CFLs cheap at a thrift store, and one of them is a Maxlite 32W that looks like this:
https://www.amazon.com/s?k=maxlite+growight&ref=nb_sb_noss
although it doesn't say growlight, but I don't know why else you would have one. I've never seen a super CFL that size.
 
Is there any risk to running one of these in a basement ceiling fixture?
 
During the winter I do my morning wakeup under bright light, this kind of lamp might be easier than my current setup. But not if it's going to explode or break during use.

So you have a non-growing use for it, but no-one else has?

nothing beyond the usual minor risks of lamps.

why do you think it would it explode? Seems an odd idea.
Break...all lamps do if whacked.

are. I never saw that symbol.

Bear in mind Radio Shack doesn't make ANYTHING. They are a reseller.
A lot of their gear, is branded Micronta or Realistic.
 
Secondly, Realistic and Micronta are Japanese suppliers. I wouldn't
expect them to 100% follow US standards for schematics.

Well, here's something 100% accurate: that meter is a piece of shit and of no real value to anyone who requires a good meter and knows how to use one. Total waste of time.

I have a whole pile of cheap meters as well as good ones. They're useful IME.

Conspiracy theory notwithstanding...
 
I suggest that some designer made a bad decision to use a cheap
part to manage the flashlight modes. Some manager made an uninformed
decision to remarket the result. Everybody saved a penny, except the user.
Caught with their pants down, some vendors are now advertising flashlights
with zero parasitic drain.
It's unlikely that Duracell had any malicious intent in this.
 
There really is no clean fix for this. If you use your flashlight every
day, it won't affect you much. If you use it infrequently for emergencies,
you absolutely, positively want it to work when needed.
About all you can do is put an insulator somewhere in the battery
assembly and remove it when the emergency happens.
 
Next time, buy one that advertises zero parasitic drain.

I just hate it when someone ruins a perfectly good conspiracy theory.
Never attribute to malice that which is adequately explained
by stupidity. Hanlon's Razor.
 
Standby/parasitic current drain of various flashlights (including
leakage current and estimated battery life):

There is already a class action suit to prove otherwise:
 
"Duracell Class Action Says LED Flashlights Drain Batteries Quickly"
<https://topclassactions.com/lawsuit-settlements/consumer-products/877506-duracell-class-action-says-led-flashlights-drain-batteries-quickly/>

<https://www.classaction.org/media/siddle-et-al-v-the-duracell-company-et-al.pdf>
(12.4MB)
The case seeks to cover a proposed nationwide class of
consumers who bought Duracell's 250, 300 or 350 LED
flashlight models from Duracell, Costco, Home Depot or
Amazon during the to-be-defined claim period.

With alkaline cells, I like to store them outside of the device in a
plastic bag. I've had too many problems with alkaline cells leaking
all over the inside of flashlights, radios, and toys.
 
>Next time, buy one that advertises zero parasitic drain.
 
Probably a good idea. I guess I've been lucky as none of mine seem to
have the problem. However, I haven't measured it, so I'm not really
sure.

You can sue anybody for anything. Sometimes you even win.
BUT
I don't expect anybody at Duracell ever sat down with the evil
intent to sell defective flashlights as a means to increase battery sales.
It's much more likely that someone in purchasing decided they could
make a buck on flashlights and did zero evaluation.
 
I skimmed part of the attached links.
 
Should they be punished for not recalling them? Probably, but what
is the appropriate punishment? We all have stuff that performs
less than expected. Where do you draw the line?
 
I'd bet that Costco took back any presented for refund.
Don't know about the others.
 
The people with flashlights ain't gonna get rich, but the lawyers sure
will get rich off this lawsuit.
 
I have several of these that I bought at garage sales. Didn't take long
to discover why they were almost free. I probably won't be able to make
a claim without a receipt. Stick a piece of plastic between the battery
pack and the spring.
They'll be fine when needed in an emergency.
Another strategy is to leave batteries in the flashlight, wait for
them to leak, get reimbursed for leaky batteries.
 
If I were to sue Duracell, it would be over leaky batteries that ruin
the devices they power. I'd get behind serious punishment for that.
Although I've had them replace seriously damaged devices on demand.
 
It's all about the Benjamins. If replacement cost is less than the
additional profit, that's what controls the decision. In this case,
they pissed off the wrong ambulance chasers. ;-)

Usually companies are busy looking for the next wheeze, the next way to sell more product. And we surely know that a lot of these ideas are knowingly not in the consumer's interest.

a company that size with a large reputation doing zero evaluation? Not credible

afaik parasitic drain is not a crime. I don't know any law that prohibits it.

Batteries leak, it's inherent in the design. If you force companies to pay out then the price of batteries goes up. Effectively you force everyone to buy an insurance policy. Why aren't you blaming the product mfrs for not using gold plated contacts that wont' corrode & easy wipe battery holders?

I have a vintage Micronta (Radio Shack) analog multimeter. model 22-214.
Its a great meter. And I usually prefer analog meters for most stuff.
(old habits are hard to break).
 
Anyhow, the meter works fine except the continuity selection. There is a
buzzer inside thats supposed to beep. It does, but it's very quiet. I
can barely hear it. If I apply some pressure to it, with my finger or a
pencil eraser, it gets louder but wont stay that way. So I know it's the
buzzer itself thats bad, not the circuit.
 
Since I can no longer get replacement parts from Radio Shack, I have to
get a generic replacment. All my years of electronics, but I have never
replaced or used a buzzer for anything.
 
How do I select the right type? There is 2 to 2.5 volts DC going to the
buzzer when it's active. So, I need something for that voltage. It's NOT
mounted on the printed circuit board, so thats a good thing. There is
plenty room in the case to mount anything. Glue it, or screw it on. So,
how do I get the right buzzer? Or is it just based on the voltage? I
really dont know much about them.....

1. voltage
2. physical space limits
3. Magnetic (low frequency bzz) or high rfequency piezo.
 
Any replacement will be too loud, soft glue on the bleeper will be needed.
