Electronic Fly / Mosquito Trap | Can I Fix It?

- My Daughter asked if I could have a look at this electronic fly / Mosquito trap as my Son-in-law plugged the wrong power supply into it and zapped it!
It is just totally dead and shows no signs of life. Let's take it apart, see if we can diagnose the problem and hopefully get it working again.

Nice workaround Mick 👍
Cheers Vince!
Bloomin' heck those were small components that you removed and replaced. I was very impressed!
Thanks Nick 👍If you think that was small you should check out the video I did on the old ramtex space invader blockbuster game!
5V barrel jacks are an accident waiting to happen.
Yep, especially with multiple adapters lying around 😂😂
Seriously. Just why not USB on both ends?
Good point! I seriously have no idea 😂😂😂😂
On a traditional device there would be a marking near the socket with the correct voltage and polarity or ~ AC. I prefer a barrel connector over a USB, because USB is a data port. Nobody should be encouraged to plug in a bug zapper, table lamp, vacuum cleaner or similar into a computer.
A surprise from a barrel connector happens if the center pin is ground/negative, as is sometimes the case on radios, because they use this arrangement to disconnect the batteries.
Things like this shouldn't need a micro controller. Some descrete components would suffice to make the LDR turn it on at night, If you have a problem with flies, why wouldn't you want this thing running 24/7?
Agree, although with a lot of things it's cheaper to throw in 1 microcontroller than a handful of discrete components..
Nice MacGyver bypass. If I had this trap I'd add a mechanical on off switch to those two points that you shorted and the light and fan came on. But a blob of solder works just as good.
Thanks 👍
Happy fathers day . Great video again ❤❤
Thank you! You too!
Happy fathers day!
Thanks! 👍🙂
Nice one. Skills. A simple switch on the power lead would have made it even better.
Thanks Bones 👍yes good shout on the power lead switch idea!
Good work around, only thing you could have checked was the cheap momentary button. They get crap in them and can not fully open, but it did make a good connection when pressed. But still, on all the time isn't an issue anyway.
Thanks 👍It stopped working after they plugged in a 12v adapter by accident, and that went straight into the small microcontroller. I'm sure I did check the push button, perhaps that bit didn't make it on the video (can't quite remember)😂
@@BuyitFixit Oh well, they were just destined to kill it!
Impressed how fast you soldered the two resistors back.
By the way, for measuring smd resistors I have measuring tweezers which are very handy. You just hook up the wires of these tweezers to your meter and grab both ends of the smd resistor with the tweezers.
Thanks Diane, I'll have to look into those tweezers, they sound handy. Thanks for the tip 👍
Some of those smd components are too small for me to work with and it seems like you can handle them with ease. Anything smaller than 1806 (I believe that might be 4516 for Metric Land) and I quit. Great job on the workaround.
Thanks 👍Not as small as the bond wire on that LED game tho 😂😂😂
But the most important question is, does it even attrack mosquitoes? Living in a rural area with lots of mosquitoes, I tried many gadgets claiming to kill only mosquitoes… turned out the killed everything, except mosquitoes…. And I love having those other little creatures around… grrrrrrr
I'd doubt it, from the Amazon reviews it didn't catch much at all 😂😂
Great fix nice work around, I was cringing as I saw the big choke and cap for the ccfl tube, I was thinking he’s gonna get a bolt up his arm in a minute poke his fingers about 😊lol
Thanks. Lol, it would have been entertainment if I had of 😂😂
@@BuyitFixit exactly lolol
Great video as usual, do you think the chip could be a simple timer to limit the run time to say 4 hours?
Probably a microcontroller programmed as a timer 👍
Was it your daughters husband or your daughter lol, I've taken the blame a few times for my wife and I'm sure all loving men have for theirs 😂
Yes indeed 😂😂
3:55... that's exactly what it does, just sucks bugs into the bottom and traps them (effectively alive until dead).... I have one exactly like this one, but molded differently for the 'inlet' part of it... it uses a 5v "PC" style fan
Thanks Beezy King👍
~ the fan injurers the flys and the breeze dehydrates them ✅
If it worked by shorting the LDR, why didn't you test the LDR to see if it was always open circuit? If it had been and you replaced it with one that did create a voltage divider when the dark hit it, it might have fixed the thing in the way it was intended.
Could always place it in a smart outlet or a outlet with a timer. Was it possible to short the on/off switch and still have the light sensor in?
Unfortunately not, the microcontroller seems to control both. I think it got shorted internally due to the over voltage. I'm not sure why shorting the sensor contacts made it work. Alternatively I was going to remove the chip totally and just wire the output pin to 5v which would have done the same job.
@@BuyitFixit I see no much to be done then, and as you said better then going in the bin 😊
Most Components always tend to read different when in circuit.
Agree, that's why I normally remove if they don't show the expected value.
Hello just wondering what microscope are you using and any good recommendations .
Nice videos man love it.
Hi mate, thanks. I just did a review of an Adonstar microscope, and I compare and show it against the microscope I already had. Have a look and see what you think.
@@BuyitFixit I have watched the video and it’s awesome really but i dont really like that type of microscopes with a monitor i m searching for and tricolour or only an digital microscope.
@@bojidarandrov3612 I bought mine second hand from Ebay. I think it's a clone of the amscope ones. It had a 48mp camera and the arm that clamps onto a desk. Have a look on Aliexpress I'm sure you'll come across it now you have seen my setup 🙂👍
Do you think these devices ever work as advertised? I have bought a few but they never seem to work as advertised
If it didn't work, why fix it? I'm assuming that if it didn't do anything, they wouldn't want it repaired.
I checked the reviews and it didn't get very good ratings...
I'm not sure how long they had it for before it got fried, the fan etc looked very clean inside so perhaps they didn't use it very long to find out. I know it got fairly dismal reviews on Amazon 😂😂😂
If they really got rid of mosquitoes they'd be way more popular in places like Manitoba.
It lures the fly with the light and the fly is sucked into the fan where it is injured by the fan and lands into the mesh cup ~ the breeze will dehydrate the maimed fly and eventually kills it. These are very efficient at trapping and killing small flying insects without zapping them, I had a Maplin n’gadget fly vacuum (based on the same principle as the trap In this video) unfortunately it recently died before Christmas 2023 and l have bought one of those rotary fly traps
3 fuses and non protected the chip.
Poor Flys 🙂
Yes I thought it would zap them with HV. Seems it just dehydrates them by blowing air on them, or it just keeps them nice and cool in the hot weather 😂😂😂
Electronic. Fly. Mosquito trap. Can. l. Fix. It
Kyou left the light sensor off
Main control chip (MCU) was fried, which takes the input from the light sensor and the power switch.
Why couldn't you just buy a new micro controller or would that need programming.
Yes, it would need programming. The code isn't publicly available and the microcontroller would probably be read protected.
@@BuyitFixit can they read protect them, then. I was thinking of buying a programming kit to have a dabble at it.
@@jonome9565 Most microcontrollers have a read protection setting. I'm not sure what microcontroller this was as it didn't have a number.
@@BuyitFixit it's just I saw the Cod3r was reprogramming chips to make a disk playstation into a digital version. He never mentioned a read protect. You learn something from every one of your videos. Nice work. :-)
Thanks. It depends on what chips they are. If it was a flash chip then they are made to read and write. Microcontrollers have a cpu ram and flash all in the one chip. You can usually erase them and then use them again or sometimes you can use a glitch attack to bypass the protection.
