[@Muonium1]

I don't know that the explanation of dark noise and increasing PIR gain when the light is off is necessarily correct. I think a more probable explanation is simply that the surface of the cardboard when it's in the box is so close to the PIR and LEDs that it's reflecting the thermal infrared radiation of the warm LEDs themselves onto the PIR, and because the thermal mass of the LEDs is so low, they cool very rapidly as soon as they're turned off and the change in amount of reflected mid IR onto the PIR is rapid enough to trigger it. When the light is mounted on a wall in a normal room the adjacent walls are much too far away to reflect a significant amount of IR back onto the PIR detector and it can't see the heat of the LEDs. Put some insulation over the LEDs when back inside the box, it will probably stop the cycling.

[@drstefankrank]

I second that. My expensive KNX PIR have configurable dead times to not trigger by some lights turning off and cooling down.

[@taukakao]

Yeah, my thoughts exactly. Though the gain theory is also not that far fetched. Especially with such a cheap product.

[@two_tier_gary_rumain]

I'm not so sure. Don't forget that these come with an opaque plastic cover (which Clive didn't show). That plastic would also reflect the LEDs internally. For the ones I have, the PIR sits in a hole in the middle of the plastic cover. But, light bulbs with built-in PIR have the sensor inside the glass/plastic bulb. So, without Clive showing us, we don't know. Anyway, this would need to be tested to determine the actual cause. You could insulate the PIR instead of the LEDs by using a bit of tubing. This leaves the top open but stops the PIR from sensing around the sides.

[@taukakao]

@@two_tier_gary_rumain The plastic would need to be quite transparent to IR so that the sensor even works so I don't think it reflects as much IR as the cardboard box.

[@alunjones3860]

@@taukakao It seems unlikely. Don't forget that everything above zero emits IR, including the sensor itself. The sensor doesn't actually detect IR directly, but changes in temperature, due to IR focused on it by the lens. The sensor needs a change in temperature, in order to generate a voltage: remember the second law of thermodynamics states there needs to be a temperature difference to do work and a change in temperature has that effect, as the part of the sensor under the lens is will be at a different temperature, than another part of the sensor, until of course it reaches thermal equilibrium.

[@lloydevans2900]

Putting a couple of 500 mAh cells in parallel sounds fine - as long as they both come from the same brand of discarded device, so they would likely be the same capacity. I have noticed that many such devices contain cells which have "500 mAh / 1.85 Wh" printed on them, but the physical size and weight can be variable between brands. The diameter of the cell is usually 13 mm, so the variable is in the length, which is easy enough to compare. They also usually have a 5-digit form factor code which works the same way as the common 18650 cells (18 mm diameter, 65 mm length), though I haven't yet found an explanation of why this needs the zero at the end. If the salvaged cell is a 13350 (one of the most common sizes used), then it most likely is 500 mAh. If it is shorter than that (the next most common size is 13300), then the capacity is almost certainly lower, regardless of what the label on the cell claims. Most of the 13300 cells I have found were either 360 or 400 mAh - and yes, I have found a few of that size which claimed to be 500 mAh, but turned out to have a real capacity at least 100 mAh lower. Why does this matter? Because as I understand it, if you are going to link two or more cells together, whether in series or in parallel, their capacities should be matched as closely as possible. The potential for damage when mismatched cells are linked is worse when they are in series, because when the lower capacity cell is fully discharged, it will be reverse biased by the higher voltage remaining in the other cell(s). Whereas if mismatched cells are linked in parallel and the lower capacity cell is fully discharged first, the higher voltage of the other cell(s) will attempt to partially recharge the lower capacity cell. This probably wouldn't damage the cells all that much, but since no recharging process is ever 100% efficient, the effective total capacity of the linked cells would be reduced, compared to the sum total of all their nominal capacities. So if you are going to add a pair of cells to the device in parallel with the original cell it came with, it would be best if the added cells were the same capacity as the original cell.

The zero is probably to indicate it's a cylindrical cell, as usually the rectangular ones have three dimensions.

That auxiliary light sensitive device marked CDS1 is on both boards. The marking is probably down to the designer originally intending to use cheaper cadmium sulfide LDR but later finding that it would be too slow or wasn’t compatible with the chip they had to use or something similar, and the board markings were forgotten when they changed to a silicon device. Would the constantly increasing gain issue not have happened if they had stuck with the original design, or is there not enough evidence left after all the changes to tell?

Cadmium is one of the elements that the eco-warriors have pushed to have banned from electronics.

Translating software can be so entertaining.

Could it also be caused by the slight temp change in the carton when the light is off that triggers it on? I had a light do this. Well not in a carton but a surface nearby.

You could, if you so wished, after fitting the batteries to the pc board, put a small switch in the circuit so that the lights could be turned off. However, I would think having flashing LEDs and a small tune module would be suitably annoying. Good post 👍

This seems like a device which was made to be sold, not made to be used.

While I don't look often here in San Diego, California, I've only happened across one discarded inhalation device... Where to look if you really want to find 'em, anyone know?

[@tim1724]

I have never encountered such a thing here in California.

Anywhere people will linger for a while.

...Also rare to find chucked out in Australia. ...Govt regs strongly discourage. Advertising not allowed. ...Still, there's always a couple of glitzy shops that happen to sell the devices close to every secondary school...can't imagine why!

Find a hipster bar with lots of vapers. Ask the bar tender to put out a bucket with a sign saying it's for vape battery recycling. You'll have buckets full every week & never have to buy batteries again.

[@michaelturner4457]

I think disposable single use vapes("inhalation devices") might be illegal to sell in America, unlike the UK.

I hope their space program does not kill more people.

Maybe it should be called a FOaD light
