Exploring an unusual prototype cockroach zapper.
HTML-код
- Опубликовано: 12 сен 2024
- A rather unique opportunity to explore a prototype of a product that did make it to market, but seems to be hard to find.
I've got to admit that I felt a bit uncomfortable making this video. I get the feeling that the inventor put a lot of time and money into designing and trying to get funding to bring this product to market.
A note came with this device suggesting it used the antenna disabling technique.
There's a broad-spectrum patent that seems to be associated with this product, but it doesn't specifically mention the antennae effect. Just that the antennae will bridge the gap between the electrodes. It seems to suggest the main difference from a traditional insect zapper is the horizontal plates and darkness more suited to crawling bugs.
It also suggests a timing of 30 seconds of zapping every 20 minutes.
Here's a link to the patent, which expired in 2002:-
patents.google...
The engineering of the case is complex and stylish, but would have made the unit quite expensive to manufacture in this form. If the product had taken off and been a huge commercial success, the inevitable clone products would probably have used a much simpler two part case that plugged together with a single base plate contact pin and safety switch. The circuitry these days would be the inevitable 8-pin microcontroller driving a small CCFL style transformer and multiplier arrangement.
I'd like to know the history of this unit and how much work and experimentation was involved in testing the concept and designing the unit. The resin moulded case is immaculate and would have been expensive and time consuming to make as it predates 3D printing.
Here's a link to an Australian science/art museum page showing one of the commercial products with the simpler case and latch at the front:-

Plot twist: The guy who invented it was only interested in how long he could manage to keep Clive out of it.

In my totally unscientific experience, roaches seem to be quite attracted to electromagnetic fields especially if there is any warmth related to that. Thus, I find them crammed every which where around things like wallwart capacitance dropper phone chargers, small electrical devices that generate waste heat, like external hard drives, and lately, inside AC-powered smoke detectors, which are slightly warm when connected to the mains. Anything and everything electrical or warm brings them in. In that case, a device like this zapper should be feasible. Whether it works or not, I don't know. But the bit a out trying not to kill them so they don't release the eggs is a bit worrying. The injured roach is still going to wander off and eventually decide it's about to die and eject the eggs anyway. Personally, I find lots of boric acid powder works great for killing roaches. They carry back to their nest and they all die and leave behind a bit of fire protection in the process. Plus, you can sling it all over your house and people will think you've got a lot of cocaine. It's a nice way to meet neighbors.
Roaches are attracted to Heat Like crazy, I opened many consoles where a roach climbed in the PSU and shorted Something
They love heat. I once saw a roach crawl into an alarm clock. When I opened it up, there were like 30 of them hiding in there and they scattered in all directions. It was disgusting.
Capacitive dropper phone chargers? Where do you find such monstrosities? Do they even provide enough current for an almost-decent charge?
@David Burgin Baaad son 😂.... i would have done the same 😅
@@diamondfailer11 Aperture Science. Don't act like you wouldn't do capacitor droppers 😂
I have had one of these for over 10 years (same design as your) it still and has been in service all this time, and works great.
I would like to point out that in 99 percent of cases all the roaches were killed while inside the zapper, hence it not only vaporises there antenna but zapps there guts also.
My unit turns on and off in a regular interval, all the roaches die inside, none leave alive.
Ah, that better fits the patent description.
Can of fly spray and a lighter has a similar effect. By similar I mean, cockroaches enter my house and they all leave dead.
@@kaydog890 Yep .. but only problem there .. if you see one theres typically another 20 (theres some stats somewhere) you dont lurking in dark hard to get to places.
@DARK APPERITION Hotel California... on in the background 🤣
i remember listening to this bad boy frying the bejezus out of roaches
My dearest Clive- that thing's mode of operation can only be described as "heartbreaking" by someone who's never had to deal with cockroaches.
They're like rats only smaller- they will chew their way into any food product and foul it. They will be in your clothes as you taker them out of the dresser to put on in the morning. They will happily crawl into bed with you to stay warm. They will also crawl into any electronic device for the same reason and make it extremely unpleasant to troubleshoot with all their little corpses and cockroach shit.
I was raised in southern California- they were bad enough there. When I moved to Arizona I discovered that above about 85F the little bastards can *fly*.
Any product or device that shortens their lifespan is fine with me. I learned to appreciate the benefits of Diatomaceous Earth rapidly as it's nontoxic to mammals but is hell on insects.
I don't think he was describing the effect on the cockroaches as heartbreaking, but the failure of the product. Some guy put a lot of work into this design, and probably lost a ton of money doing it.
@@jeffspaulding9834 Yeah, that definitely happens way too often. W need more history on the product and the inventor.
Ditto above.
What on earth are you blabbering on about? I'm really intoxicated and heard 2:19 correctly. Who in their right mind would find killing these bloody cunts heartbreaking?
It's about investment, not just monetary but your time and often dreams. It's heartbreaking to watch it fall. What's worse is having other companies copy your idea with minor changes and succeed.
American humorist Sam Levenson described his childhood as a life of plenty, adding " -plenty of relatives, neighbors, boarders ... cats, dogs, *_cockroaches_* , and the like".
@David Burgin Wow, small world. I did residential flood irrigation for about twenty years in Phoenix.
That wasn't me though, I swear!
Good advice regarding patent firms. Steer clear.
Not necessarily. I'll write a bigger comment
@@herseem That must be a huge comment.
With or without antennas, cockroaches are never likely to get a good reception!
@Matt Quinn They were coaxed into the trap with yeast, perhaps not the best of quality ;) Probably had a high die-electric constant though!
No.
Zaps the antenna. The roach returns to its nest and is driven crazy by no bars of LTE signal and commits murder suicide. That insures it’s babies don’t have to endure life without cell phone internet. A fate worse than death.

I like that, that's good, really good.
"Maybe they experimented..."
Okay, send one in. *PFLOOM* Alright, need more resistors. Get another roach ready.
That probably is what happened. Fine tuning of voltage and current.
Never forget the brave roaches who gave their lives so that their brethren could be crippled in a very cruel way.
"Zap all you want, they'll make more."
@Bill Whittaker How do you know they didn't volunteer?
This is the only time I've ever felt bad for roaches!
LOL Holy eff'in a.
Literally the last thing I was ever expecting to hear from an electronics channel were the words, "Bad Dragon."
But uh, lewd props to you my friend.
Instant subscriber!
Yknow, this channel was pretty much the last place I'd expect a Bad Dragon mention from, got quite a chuckle out of me
"It doesn't kill the cockroaches, it just fills them with self doubt as to whether or not they are in the right house."
My guess for putting the primary over the secondary is it may give better coupling and lower leakage inductance, which is important for flyback supplies. Unlike 50/60Hz transformers, flyback transformers need very good coupling if the losses are to be kept down at high frequencies, which is why they are always wound on a common bobbin as well as also often interleaving the primary and secondary windings. If the coupling is poor, there will be lots of power that wont be transferred to the secondary side.
I logged in especially to see the comments and say this. Well put!
Never realized prototype cockroaches were that big of a problem.
There were many features cut before production. Production cockroaches don't breathe fire, for instance.
I just got one (April 2021) from a garage sale. It works perfectly, it kills the cockroach dead without exploding them to pieces. I use Vegemite for bait.
Clive, I love your use of printed photos to do reviews. It is brilliant, and wish more people done it like this. Photo of back and front (flipped), really makes it so much better than just staring at the image. Photo with pointy finger, and ability to draw with a pen / marker, makes it so much easier to follow, or do reverse engineering. Cheers.

Some parasitoid wasps use cockroaches as live hosts for their larvae. It's really interesting how they capture the roaches!
The wasp is much smaller than the roach, so she can't overpower it by main force. Instead, she uses a pair of stings with surgically precise placement, first in the thorax and then in the brain, to temporarily paralyze the cockroach. While it's unable to move, she severs its antennae with her mandibles, biting them off a short way from its head. When the venom wears off, the roach can move again, but without its antennae, it won't flee on its own. This allows the wasp to take hold of one of the remaining antenna stumps and use it to direct where the roach will walk, right up until she's backed the roach into a burrow she previously prepared. After that, all that's left for the wasp to do is to lay an egg on the roach's abdomen and seal up the burrow. When the egg hatches, the larva chews its way into the still living roach's body and feeds on its organs, instinctively saving the most vital ones for last so that its provisions stay fresh and able to support its growth and eventual pupation into an adult wasp who will ultimately repeat the process to raise her own babies.
Nature really is beautiful!
Wasps are nasty horrible things. Cockroaches aren't nice either but at least they don't sting.
Thats like a horror movie script on a tiny scale. Nature is basically evil.
I was horrified to learn that stingers evolved from reproductive organs. Now when I’m stung I take “ the morning after” pill
Simon Tay Wasps have a role to play in ecologies just as any other animal does. Are lions horrible because of what they do to antelopes?
And too, wasps won't sting you if you behave nicely to them and stay well away from their homes! I take close-up pictures of wasps, yellowjackets, and hornets all the time, and by "close" I mean I have a camera lens and three big flashes going off six inches in front of their faces. They never mind at all! Most don't even seem to notice, and I've never been stung doing it, or stung at all by any bee or wasp who I hadn't accidentally frightened first. It's not hard to avoid, really! Keep an eye out for them and be careful to leave them alone, and they will do you the same favor. After all, they're just trying to get through this life, the same way we are.
Dick Jokes And Bondo Oh, you don't need to worry about that! I mean sure, there are a couple of families of wasps that synthesize special viruses found nowhere else in nature, that they use to subvert their hosts' immune systems in order to protect their larvae. But those families of wasps can't oviposit in humans, and their viruses wouldn't work on us even if they could! All you have to worry about from any wasp that can actually sting you is venom, and as long as you're not allergic, all that does is hurt a little bit for a few minutes. No big deal!
That is Respect. “I don’t want to completely reverse engineer someone prototype”.
Thanks for debugging that!
LMAO
What you did, I see it.😁
I repaired large stereo receivers as well as other stuff in a repair center. They like the heat in these units as well as the kitchen aerosols that get into these units from cooking. I find a lot of grease coated components covered with lint. Roaches love this food and the warm environment. We called these units "roach coaches" as well as the lunch truck. These units has a certain smell and are full of roach droppings and old carapaces. Sometimes you get a wave of roaches when you take off the covers. My company had a good QC department that if you mention "cockroach" or any derivative on the repair ticket, you can be fired. They didn't want us to upset the customer.
Lived in South Carolina way back in the 70s while in the Air Force. Moved into a duplex that had been unoccupied for a few weeks. First night I turned on the heat I apparently woke up the sleeping horde of roaches. Sure wish I could of had one of these then. Would have been so satisfying to hear that little spark. I wonder if there would be a faint scream after the zap.
I really appreciate the amount of respect you're paying to the invention of someone you don't know. shows what a nice person you are :)
Must be for old cockroaches, new age roaches have digital antennas and can be folded up for convenience 🤣
They are full of them blasted five gees these days, I tells ya!
FYI thought you might be interested Clive, the two gents that invented this zapper were from Rockhampton Central Queensland, Australia, working at CQ (Central Queensland University. Back in 1988 the original problem from memory was the miniaturisation of the components to fit a small package which was a great concept in those days. Must have been difficult. Also they were working on a sign wave inverter. Back then the main inverter was a square wave type.
Sine wave, named after the sinus trigonometric function.
Cooking cockroaches with electricity, now, are we? Bet that smells amazing.
Probably like popcorn!
You beat me to it.
Just threw away a microwave infested with roaches. Had absolutely zero desire to find out what it would smell like when that device was used for cooking. Hell no. The roach problem has been controlled. I can just get another microwave, which I wanted to do anyway.
@@LatitudeSky why not just zap the roaches. Hammer the little pests
I'll go large
The primary winding has been wrapped around the outside of the secondary winding for accuracy of control and efficiency of the transformer itself.
I never thought I would hear Bad Dragon mentioned on your videos, lol. That caught me quite by surprise! Keep making these great videos, we all enjoy them profoundly!
The mode of operation reminds me when CB radio became popular in farming. Surprising how many tractors encountered overhead mains cables and a very charred CB would find its way to my workbench.

Clive knows about Bad Dragon... This leads me to believe that Clive is actually a bear in a human suit.
Killing roach egg casings is really difficult so doing things to prevent the females from doing an emergency ejection is definitely smart thinking but really difficult to pull off, roaches are smarter and more sensible than people think.
Just need to make one big enough to fit in the houses of parliament, loads of cockroaches there... :P
hope they don't expell their eggsacks or we'll get more new ones ;)
Can you do a lend-lease to us Yanks? We've got a fair few of them in WDC. And even more in every state.
USA needs a super sized one be nice if it was powerful enough not to leave stains
We'd have to bait it with wads of banknotes.
I think something along the lines of a fogger may be more appropriate for that level of infestation.
Bigclive's explenation of what happens when a female cockroach dies made me have a little bit of my dinner all over again.🤢

Insect Anatomy 101 - All have 6 legs and 3 main body parts:
Head
Thorax
Abdomen
Legs and wings go to the thorax!
Edit: Responding to 3:12 where he said "two big long legs in the back and I think that's it." A couple more legs and I'd think it was engorged and embedded tick (antennae=skin).
It's considerably modified from that body plan after you step on it.
@@Amiculi LOL! Sure, but this is mostly a critique that should help if he ever draws another. ;)
yea, cause now when he drew that i thought it was squashed 6 legged horse with broken legs and i got confused
@@MrKfadrat
He expressed concern with his ability to draw it and that was something simple/basic to immediately improve any drawing that ignores these. Remembering the basics of insect anatomy will help with his stated concern in the future.
Applied here, it would force him to draw jointed legs of varying lengths to get them around the body where he clearly wants them. It may also remind him to draw wings.
...and let's not kid ourselves: legs and wings to the thorax is as basic as "all insects have six legs," even if many of us forget as we leave grade school.
well, its as basic as your interest goes i guess
Clever design. It must have taken them an age to perfect.
My father had one of these, he got it in the early to mid 90s. They came with a wallwart adapter and some bait tablets too. I recall it wasn't all that great, and it made a high pitch fizzing noise at seemingly random times.
Maybe we got a dud unit, but I also remember my father pulling it apart (he was an electronics technician) to try and fix the noise, and he also spent a long time just trying to open it up without damaging it.
that awkward moment when Bad Dragon has become so commonplace on the internet that you hear about them on a random consumer electronics vlog.
they should branch out into e-stim and name the first model "Big Clive" in your honor lol
Knowing them it would be the "Even Bigger Clive".
clive confirms he knows what bad-dragon is
Interesting video. I think this is like when you have only a hammer everything is a nail. The designer apparently would rather use a ton of analog old school components when a single super cheap microcontroller could have replaced most of them and improved the device in many ways. Oh well.
The design is from about 40 years ago when all you had in microcontrollers were ones like 6800, Z80 and 6800. They would not have been cost effective in those days. Analog was the cheapest way to go.
This is an absolutely gorgeous (aesthetic and functional) design. Wow. It deserves to be in a museum for sure. Glad you 'didn't want to break it'...It's like a Lautner architectural masterpiece.
In reference to 3:52. Reproduction in bugs is like something out of a sci-fi nightmare. If you're brave (and not squeamish about bugs, or squeamish in general), read up on aphids and mites of the genus Adactylidium.
13:10 According to the patent it powers on for 5 seconds every 7 minutes, so I'm guessing the plan there is to make it more likely to catch both antennae at the same time, since if it was just on all the time it would be likely the insect would lose a single antenna and run away.
I understand less than half of what you’re ever talking about but I still watch anyway
I remember years ago, an advertisement in the US for a product called the Roach Motel.
Their slogan was:-
'They check in, but they don't check out'. 🦗
Those were, I think, a combination of strong adhesive and a mild poison on the inside of the very cheap traps?
Paper ones like little rectangles with offset paths, and later came the plastic ones of various shapes.
Still sold: www.amazon.com/Roach-Motel-Traps-2-Ct/dp/B00AA8X13A
That gave me a hell of a nostalgia flashback. Didn't those ads have a really ominous-sounding narrator?

Humans at its best. Finding new ways to kill stuff. Not sarcastic, just admiration.
There was a product marketed around 1991 in Australia called the Magic Mushroom that looked similar. It was fantastic & cleared up an infestation. Only sold in TV adverts & we could never find another. I keep searching every couple of years for one, search brought me here... I have tried a couple along the way, none as good as the mushroom was
Also, idk if I would have used the phrase, "let's explore a bit further," after the Bad Dragon reference.
The research and experimentation that went into this must have been fun.
Not for the cockroaches.
I can't help but laugh at "lots more little mini cockroaches."
I like how you sometimes take a different approach to describing things, not just about how cockroaches eject egg sacs.
I come for the "ONE MOMENT PLEASE" said with such style😃
The eggsack is called an Ootheca. Roaches are also cannibalistic which is why the modern poisons work so well as the dead roach is consumed it poisons the "eater". This happens for 5 or 6 instances so one dead roach can kill dozens more. Such is the power of the modern insecticides.
I love how that board looks. It's a shame it's so difficult to make something organic looking in most modern ESD software.
So according to the patent page, it's inventor is "Gregory Jefferys".
Maybe he can be contacted some way?
All I can find on google for this name is that he was nominated "Australian of the Year 2016". Not sure if it's the same.
Would love to have more history of this device and the person behind it.
Always love these videos of "old, retro stuff" that are more of a niché product, or a prototype.
Thanks for this Video, Clive.
When you said you were gonna draw a roach, I expected a poorly rendered sketch of the dodgy lawyer/business man from The Simpsons.
As a teenager in the 60s I'd have expected something else.
This reminds me of the "ETI electronic rat trap" (Electronics Today International - Australia) circa 1984. I believe it mutated into a cocky zapper too.
That oscillator looks almost identical to what is used in Metcal solder stations to generate the RF. They have an inverter oscillator using a crystal that runs at around 13MHz that then drives a couple stages to boost it up enough to drive a large switching transistor.
Ok, I need to *partly* challenge what Clive said about the people who can help with your inventions: It is true, it is a minefield of sharks, especially those who advertise, but there are also genuine ones and you may well need them if you want royalties. Inventing is a *very* expensive hobby until you get a licensing deal or successful manufacturing yourself. I didn't because my invention (a wave energy device) required validation I couldn't afford to be considered sufficiently low risk for others to invest in, but I had an excellent licensing agent (now retired) who also spent a load of his own money. The market moved against us and we eventually dropped the project. But doing proper patent checks first and defining your patent properly is a specialised skill and you really need experts for that. Otherwise you can end up with your invention having gaping holes in that allow someone else to side-step it and make their own, as Clive described. The moral of the story is to look for a reputable licensing agent who has a track record of helping others make money in the long run, because it will be expensive for the necessary work to get it to the point where you can license it effectively, or manufacture it safely.

> a perpetual motion machine that actually works
If we can harness the energy emitted from the founders of the Enlightenment spinning in their graves, you'll have your perpetual motion machine. And a huge fortune.
I remember seeing something on this years ago. Maybe Tomorrow’s World? If I’m recalling correctly it was intended to kill them not blind. Switching was to allow a cockroach to get inside before being zapped. They also discovered its effectiveness increases over time as cockroaches are cannibalistic and roast ‘roach was much more appealing than the bait.
I think it works this way:
It's charged all the time, cockroach is attracted by the bait and crawls in, at some point touching the HV, if the arcing is sustained, the unit pauses to allow the roach to get out.
Notice what looks like the op amp going via the microswitch and connected to that 'timing' capacitor, the op amp will probably initiate a discharge in the same way as opening the unit.
I have one and none of the roaches have left the unit alive, they all die inside it.
@@RolandElliottFirstG You only see the dead ones, you might not see the ones that lived.

Having the transformer windings coaxial like that gives better magnetic coupling than if they were on different parts of the core.
I'm not entirely certain, but its very possible the transformer windings were wrapped the way they were in this instance to reduce noise/interference, its possible those plates that were designed to shock the cockroaches could have generated their own electromagnetic field and affected the voltages, so wrapping the wires that way may have been for something along those lines. Additionally, this transformer is generating high voltage so it could possibly have something to do with just insulating the voltage deeper beneath layers. From a quick glance that's about the only things I can think of as possibilities.
The only thing I can offer about the HV winding being on the big part is that would result in more copper being used in the coil, maybe that makes a bigger / stronger magnetic field ?
After seeing Clive’s drawing of a cockroach I’m now convinced I do not actually have cockroaches. Lol
I believe putting the primary windings around the secondary is to create higher voltage with more amperage so as to do the damage to the antenna and not explode the whole insect.
Guessing it switches off so that you don't continuously fry the bug. Letting it cool down.
It's because they could sense the voltage and it stopped them going in.
That you Mentioned Bad Dragon, made me chuckle. ^.^
I remember that being on The New Inventors, a show on ABC(Australian Broadcasting Corporation) which ran from 2004-2011. It was a panel show where people present their inventions to four experts(on a rotating roster) in the science & tech sector, not a high budget show, the prize basically took the form of IP law assistance & industrial design & product marketing consultancy.
Hmmm, you note that the patent expired in 2002, the show I mentioned didn't first air until 2004 but I'm positive someone presented a device with that same name & same function, maybe not that prototype though, maybe a revision on what had originally been patented.
@@milksheihk Or "towards 2000" which later became "Beyond 2000" in the days that TV programs were made locally.

Seems like this was invented by Gregory Jeffries and the company "Danlex" was involved with it and a lawsuit(I think?) happened and they merged into Nabinda? Not much information available online. There are some patents and like I said a lawsuit document. There is an obituary for Gregory Jeffries in Western Australia. Am not sure if it is him.

It looked like a mushroom with the electrodes on the underside of the cap, and room inside for an attractant plus the battery and electronics. It operated similar to an electric fence energiser, but would detect the snail and wait for it to fully bridge the electrodes before zapping it over and over till the snail fell to the ground dead, leaving the trap ready for more victims. After reading that article, I think he was the same bloke who invented this cockroach zapper.
Do you want electricity proof cockroaches?! Because that's how you get electricity proof cockroaches!
Doesn't work that way. Electricity works at electron level on any living thing.
@@bigclivedotcom I'm both happy and disappointed that electricity isn't something that you can develop a resistance to.
@@Azlehria You could develop resistance by implanting Carbon film resistors into your veins!
@@bigclivedotcom What about electric eels? They even survive underwater...
Was not expecting a bad dragon refference, kinda shocked me lol
This kinda genius, but I think that spark would be enough to actually kill the roach and turn disconnected the power to avoid cooking it, letting others jump into the trap.
never mind the circuitry , it's the mode of death that intruiges me ......the unsuspecting roach goes in the device , gets it's sensory appendages blown off.....exits the device , then runs around the house smashing it's head into various skirting boards until it finally expires from a brain haemorrhage................niiiiiiiiiiiice
Thanks for doing this. Love hearing you analyze these gadgets.
This might be the product of Greg Jeffreys of Brisbane aka Cockroach Dundee. It was initially released around 1988. He went on a tour in the early 90s looking for additional manufacturing in other countries. He won the Australian inventor of the year award in 1991 for this product.
I think it is his design.
That flyback is kinda oversized for the purpose (and the tiny sparks it gives; still it's smallish somewhat), as we know a flyback like that can put out some juicy arcs with the right circuit. I like the idea of the primary winding being put directly onto the coil pack. That provides the best coupling actually.
I've got a plastic cover from some amiibo box that I use to trap roaches before/quickly after spraying them with some raid. Mostly to keep them from running off and dying in some random place I can't find but I haven't seen an egg sac yet. Maybe the neurotoxin death keeps them from egg ejecting?
The USA Patent office is infested with Big Corp. Lawyers paid specifically to go over any new patents and compare every tiny piece of it to 'previous' patents of their parent company and put a claim on anything that is even vaguely similar in order to 'patent steal' people's products. The patent system is now the biggest obstacle to free enterprise entrepreneurism. This was an article published by Consumer Reports? I think? Or Popular Science, can't remember which, it was a few years ago I read about it.
The circuit resembles an early He-Ne laser power supply.
I found an article in Spanish about a similar device but with a slightly different design with hi voltage rail maze, and it was set to discharge every 5 minutes. A video with the watch code kX1ZskHPIcE shows another cockroach zapper designed as a bucket with. I don't want to paste the links in this comment due to RUclips's overzealous spam protection.
My dogs absolutely hated the part where you powered it up.
The city should invest in this for the Project Houses. They NEED THEM BADLY. As an LEO I walked into some of them on calls, The Floor and counters like ALIVE. sad, just sad.
That transformer looks like the flyback transformers I used to see on old tube television sets.
Only some tiny sparks...that thing will never cook a hot dog, next!
"Doesn't just kill them," nice.
Total guess: A visual estimate of the extant additional outer windings, rewound on that thinner main core, may in fact be close to it's physical limit to contain the fat wire. Perhaps they are using a very specific ratio that coupled with their choice of fat windings in fact exceeds this spatial limitation thus they chose the obvious second option? As in a non-spec usage of a spec part.
