Exploring the expiry timer on a Sharp plasmacluster module.

this planed obsolescence is there for a reason. Honestly i would like device that will warn be before parts need replacement rather than suddenly break. You also dont replace car parts after it completely escapes your vehicle but its rather preventative.

If the internal chip was accessible it would possibly also be possible to lift the write protect pin and connect it to the adjacent positive voltage pin. That way the controller could read that it was "new" but would not be able to decrement the life counter.

My cousin had a laptop about 20 years ago that started to show a warning about falling battery levels as 'the battery was reaching the end of its expected x year lifespan'. It was a big manufacturer, possibly Sony or Samsung (those come to mind). He set the date back a year and not only did the warning disappear but he got the previous much longer battery life back. All by changing the bios date. Of course stuff like that doesn't work nowadays with computerised batteries but it was one of the first egregious examples of planned obsolescence I experienced directly.

[@Klokopf52]

This isn't as evil as it sounds. I once had a UPS go up in flames because of a expired battery. Internal resistance goes up with age, power went out, everything switched to battery, five minutes later the thing was on fire (and working oddly enough). The consumer friendly way would be to monitor actual battery heath instead of going down the lazy route of using a strict timer, but that would cost RND and timers are cheap... So its only half Evil mega corp stuff.

[@pseudonymity0000]

​@@Klokopf52 Have a UPS That was designed to be disposable. Small little desktop unit. I got it because we started getting little bouts of unstable power and wanted my computer to not be affected by the brown/black outs. It started to complain about overload One day After only a year of use when the power went out, And figured the battery Was dead. I knew it was bound to be a 12 Volt Lead acid, as the unit was pretty heavy. Looked around the damn thing, Unscrewed it, And found the shell was being held captive by the front panel... there was no way to open it Other than... Physical override. I chewed off the two tabs on the bottom with a pair of flush cutters that clipped the front on to the rest of the unit, And heaven behold. it was a standard 12v Lead acid gel battery that's used As power back up for security systems. Swap the battery out, and it was good as new. Now, whenever the UPS fails Its self test, I just slap a new one of them in there and it's still going 6 years later.

One thing about Sharp Air purification products, at least the ones from back in the day, they are very powerful, back in early 2000's when I worked as contractor for them, we had a fan belt for the HVAC decide to melt and smoke at our █████████, USA Facility - (Redacted to protect the innocent), and fire department had to come out and clear building for use again, and when we were allowed back in Sharp put in a few of their really nice air purifier units that are about 2 times larger than a Box fan, and after just running 8 hours, we moved the unit at end of day and turns out they had accidently placed the unit in front of a normal box fan that was probably 15 years old and before this event that fan had baked on black dust, and after just 8 hours somehow that damn fan was sparkling, looked NEW. SO yeah I looked up the cost and the purifier was something north of $1500 US dollars at the time, if I had the money to burn I would get them lol.

It's the inkjet thing down to the fact that you aren't running out of the high voltage module (or the print head) and only one small component, the carbon fiber tuft (or the ink itself) needs replacing. What's that, a few dozen for a dollar/pound/euro? But for 50pounds, might as well build your own timer module around an arduino and a mosfet to replicate most of the features in the original.

Or probably just reflash that pic microcontroller? it would be much easier to trace all LEDs and the button.

The negative ions generator from the '60s (which I worked with) were built with an Americium capsule same as the fire alarm, a -3000 Volt generator made with diode/capacitor voltage multiplier ladder, and a fan. The voltage generator attract the positive ions generated from the capsule, so the fan is blowing only negative ions in the room. The negative ions are those very beneficial to human health. Other devices used a dark discharge ozone generator instead of the americium - but they didn't provide any health benefit, and the ozone could be an hazard...

Expiry timer question: my camping trailer is equipped with a standard, mandatory, combined propane/CO detector that runs on 12v DC. This type of detector will work for 5, 7 or 10 years (depending on brand/model) from the first power up, then an "end of life" or "replace" signal is triggered (beep and/or flashing LED) and then the unit must be replaced with a new one. I've always wondered how can the unit keep track of time? Campers are not all used the same, many like mine are sitting in my driveway for days, completely de-powered between camping trips. Also, most RVs, at least here in northern America, are not in use during the winter months, and are winterized and again, completely de-powered for months. Still, after the prescribed duration, the "replace" signal will appear. Usage (or lack of) doesn't seem to affect the internal timer in them. How does that work?

[@bigclivedotcom]

I'm not sure how that works. The CO detectors are often based around a cell that generates a small voltage based on the presence of carbon monoxide. It may be that the cell itself stops producing any voltage when it fails. Another interesting technique I've seen is the use of a dedicated button cell discharged slowly by a high value resistor until the unit detects that it has dropped to a low voltage.

I saw that when they first appeared, but even secondhand ones were very expensive. Was it just a transistor bridged?

[@dedalus1749]

@@bigclivedotcom absolutely, just a mosfet gate and a cheap mcu refusing to drive it. They were nice enough to leave space in the "charge" unit for a C&K switch though, so that was nice of them

Does it emit ozone though? Sharp is explicitly saying it does not, in my understanding this was actually the point with this technology, opposed to regular ionizers. I've seen huge commercial units in use on the Japanese subway, and those fellas usually don't mess around, plus environmental laws are super strict on Japan, so I am inclined to give sharp the benefit of the doubt. Also, it seems somewhat unlikely that a company like Sharp would expose themselves to a world of lawsuits by claiming something that is objectively false. That planned obsolescence thing is BS though, completely unnecessary that they would do that.

[@bigclivedotcom]

They imply it doesn't. But in reality they mean that it doesn't create more than is considered ambient levels. Especially with a strong breeze to mix it into the air.

When the SIDAC conducts, I can see that it results in a pulse at the transformer secondary, but how does it contrive to produce (presumably) similar +ve and -ve peak voltages to the two brushes?

[@bigclivedotcom]

First the rising magnetic field and then the collapsing field.

[@richardmellish2371]

@@bigclivedotcomWell yes, but I would not expect necessarily the same peak voltage when the primary suddently sees the source voltage as in the other direction when the SIDAC cuts off.

Great video, Clive! Love the ink jet mini-rant - we all hate them. Have you tried methyl ethyl ketone (MEK) - great solvent - use it outdoors with gloves. Regards, David

I love seeing the little squiggle burned nto your workbench

I have rhe same brand, but a large unit for my home, with hepa and carbon filter, and the plasma thingy. And also a water evaporator. I do have to say its one of the best because, the filters last 10 years. the water evap unit can be cleaned, and there is no timelimit on the plasma thingy. So bit surprised about the time limit. As far as i understand the plasma thingy is meant to polarise particles to make them cling to each other to make them heavier, so the fall down etc. i have No idea how effective it is. But the rest works very well. Previous one was still working after 10 years with Literally 24/7 use.

Hydroxyl radicals are obviously regularly found in taxis. Does this unit eliminate their spatial configurations? There's never a glutathione peroxidase hanger when you need one.

50 quid on ebay, 12 quid on Amazon Japan just they don't seem to ship outside of Japan. And if find a 3rd party seller the price doubles with a horrendous delivery charge on top.

[@seanabsher5577]

Talk about a wild product title, but before you opened the white plastic "cartridge" i thought it'd be a good idea to find a way to read or monitor for any signal or resettable usage timer, I guess my intuition was right, but as you said, good luck knowing what was what and where everything was without opening it. But hell it made a good video anyway!

[@RS-Amsterdam]

You need a special tool to open them...called a sledge hammer 😂

BigClive, I found three largish (2'x2'x8") electostatic precipatators a neighbor discarded all clean and in good condition. Without the proper power supplying components, container, etc. I was wondering if you could recommend a way to power, reuse one of these things? I understand dangers of high voltage but have no clue as to what VA supply one of these puppies would require to work properly.

[@bigclivedotcom]

I'm not sure how powerful it would have to be, but an eBay high power ioniser module might work.

[@jacquesb5248]

very interesting. i ponder if a laser cleaner would have helped getting rid of that resin

[@bigclivedotcom]

I'm not sure how well that would work.

[@GenaTrius]

It seems like you're always having to laboriously scrape away different resins and polymers and stuff. I think you ought to co-laborate with one of these chemistry channels and level up your stuff-dissolving techniques. It's just a matter of finding the right chemicals, right?

[@luminousfractal420]

ohh i know just the guy...where is he...

[@luminousfractal420]

Thoisoi2 👈 this guy, look for his channel here, hes lovely and has a head full of chemical info. im sure he'd be happy to help.

[@vaelophisnyx9873]

keep in mind sometimes a solvent that can take away the resin may also decide to take away the component serial numbers, shells, the entire pcb, etc

[@joshhoman]

It has been some time since I heard of the Sharp brand.

[@ethernet01]

I was ready to see a handheld plasma cutter from a eletronics company

[@QIKUGAMES-QIKU]

? Sooo where does it cut from and what's it's supposed to cut ?

[@williama29]

i suspect this product may be discontinued after this goes viral and sharp noticed and this module with the carbon fiber brushes is micro suspicious

[@sausage5849]

BCDC, any chance you reverse engineer a Shelly 1PM IOT switch? I'm interested to know how they do the mains stepdown.

[@bigclivedotcom]

Probably a buck regulator.

[@Zodliness]

Nowadays gadgets have a surprising amount of R&D resources put into replacing traditional obsolescence, with small (inexpensive mass-produced) *expensive* plastic consumables. 🤔😂
