Yet another death-Dalek camping light. (fatal shock risk)
Вставка

- There seem to be quite a few of this style of camping light being sold. Here's my latest find, and rather predictably it has the same dodgy mains-referenced USB connector. This unit is a hybrid of the other two in that it offers the same flashlight function as the gold one with the same area light assembly as the red one.
In this video I also show how to make a crude USB powered charging circuit to replace the dodgy capacitive dropper based one. It's not ideal, but it's better than being fried by your iPhone when you plug it or any other metal bodied USB device into the port of this light while it's plugged into a wall outlet. An improvement would be to use a Schottky diode with a slightly lower forward voltage drop than the silicon diode I used.

"The button's not live, that's nice".
It's amazing how quick your safety standards can drop when you order stuff of eBay! ;-)
"The button's not live, that's a nice feature" Hero!
Touching the button and saying that has the same energy as "I don't think our death ray is working. I'm standing in it and I'm not dead!"
Are you planning a death-Dalek army?
🤔
Genaro Ian Or maybe a gay Dalek party?
or maybe both
Either way, you know it's gonna be *fabulous*!
ILUMINATE!!! ILUMINATE!!!
its shoking to see how bad these things are made i had a light that is the same concept but with a hand crank and evry single time i charged it by mains power the crank started spinning
It's not a flaw it's a feature.
Avamander / either way it was funny untill it blew out the battries
ExCaliberGame hahaha thats awesome. how fast did it go?
it is indeed..."shocking"
not run backwards, but run slower forwards yes !!
Non-live button, _feature_ on Chinese appliances. :-)
PAAAAARTY! Where is the PAAAAAAAARTY?!
"How much pressure do I use before my spudger suddenly changes shape?"
I have grown addicted to your videos :) And your voice lulls me to sleep through the pain .
Today I learnt
Its not smart to finger usb ports
Oh yes forget to put that part in😂
It's not smart to finger USB ports unless they got tested. Great life advice overall.
And if you are fingering USB ports, safe or not, you should probably re-evaluate your life.
***** Careful, you might catch a tingle sensation on there.
lol
Shockingly brilliant, or brilliantly shocking?
Let's find out!
We got some of those hot air guns at work. They worked quite well but we did have to add in an earth wire in the base to get the metal heating element shield to pass the PAT test.
The only voltage regulation in the original circuit is the NiMH cells. It would be funny if it fried your phone, wouldn't it? Then when you pulled the charred remains out of the charger, it fried you for an encore.
It's voltage regulation and overvoltage protection with manual feedback. If you hear the sounds of cells bulging, smell something funny or start seeing smoke coming out of battery chamber (see, it accomodates 3 senses so it's safe to use even by handicapped people) it means that voltage is too big and you gotta pull out the mains plug. If you phone doesn't charge it means that voltage is too low.
You rip the shit out of every crummy bit of electronics, but with some expertise and a smooth tone that makes it much better than shouting alot and throwing it against the wall :D Love it !
Are you planning on doing a teardown of that soldering/SMD station you have? I just bought one, but of course I double checked your channel to see if there was anything on it.
Given that I want to make a “camping light” for power outages and the like, I’m glad you’re showing what *NOT* to do.
A glass of wine and a evening with big Clive you can't beat it
Can we learn more about the FLIR hack?
It's a hack where you can get the camera to use a higher resolution, making the image equivalent to the E8's.
Someone did a video explaining it, I think it was EEVBlog.
In case anyone doesn't want to google, the hack is essentially this:
The FLIR E4 normally has a resolution of 80x60, however internally it has the same sensor as the E8 - a much more expensive model ($1k vs $5k) that does 320x240.
The hack was made for firmware 2.3.0 (and earlier), and allowed you to change the cameras OS to make it believe it was an E8, unlocking the full 320x240 resolution as well as a bunch of other useful menu options, leading to MUCH better image quality and much more accurate temperature readings (16x, in fact).
The current E4s come with firmware 2.8.0, which cannot be modified and the ability to downgrade to 2.3.0 is fairly hit-and-miss. Good news is, though, that you can often buy a used E4 with 2.3.0 or earlier firmware for cheaper than a new one.
watching these and hearing you talk about getting shocked reminds me of when i had to use an electric saw on some stuff while standing in a puddle. far from being a fatal shock, but also far from a fun one. i said bad things and got out of the puddle, then made sure it would not happen again, and got back to work.
eBay should take note of these videos, far to many parents will be totally ignorant to the dangers of these type of things. Trading standards should also be prosecuting any seller that sells this kind of stuff from a UK address. Scary to think that kids could be unwrapping these in a weeks time.
LOL what planet are you from? eBay doesn't care of sellers steal your money, let alone if they cause electrical burns
100SteveB ebay doesnt give a fuck
+The Ball Actually ebay takes customer protection so seriously that sellers basically have no rights and you can't really afford to be a seller unless you're a company who can absorb the losses from customers fucking you over. No matter how ridiculous the shit the customers come up with is, ebay _always_ sides with the buyer. The last time I sold something on ebay the cunt buying it reported it as not delivered, I sent the tracking number (which clearly showed the parcel _was_ delivered) to ebay and they still took my money and gave it back to the fucker. My friend was selling a DVR, the wank stain who bought it swapped the innards for his burnt out ones and returned it as not working. My friend demonstrated the serial number on the board no longer matched the one on the case, but that fuckwad still got his money back.
So no, ebay _does_ care about buyers. Unfortunately they care to the point where individuals can no longer afford the risk of selling stuff on there.
eBay doesn't care about individual sellers like you, but power sellers from China get away with murder constantly. There are absolutely no standards. I'm currently dealing with some BS seller who claims the items were located in the US when clearly they were shipped from overseas causing huge delays.
I just want to make sure I understand the current path that causes the mains voltage to appear on the USB port.
So a shock risk exists if you plug the mains cord in backwards (this puts the dropper capacitor in series with the neutral instead of the live) from the circuits perspective this doesn't make any difference since it's still in series with the dropper capacitor and will still work normally.
However when you touch USB negative you're essentially bypassing the dropper capacitor on the neutral through the ground to neutral bonding connection at the main panel and because the capacitor isn't in series with the hot you will receive a full mains voltage shock minus the negligible .7 volt drop of the bridge rectifier?
You know what might be fun is to take a trip to poundland and gather a modest collection of electronic gizmos and see if you can build something more sophisticated out of the parts. Fun episode :)
that would make an interesting episode...
However a similar challenge would be to get a load of poundland crap and then make something even more shit out of all of the parts.
one rule, the finished product HAS to perform some sort of function at the end
Would it be possible to squeeze a boost converter in there so you could get that USB port up to the proper voltage?
Yeah, search for eBay "usb step up" would be perfect size.
So I'm guessing this one is a straight Dalek? =-(
Amazing there is more than one model.
This Dalek is still in denial because it knows the church does not approve of Dalek fornication.
I love you, Clive. Never change.
I like the gay daleks best!
Time for all Daleks to leave the church and live free, regardless of their orientation.
I've got some odd images in my head of 200 Daleks assembled in a 17th century church for service. Think of the hymns.
EXCELLENT episode, Clive! I think the reverse engineering and complete rebuild is a *fantastic* way for people to learn. Sister Boom Boom would have LOVED your channel. RIP.
Loving the live mains voltage checker probes and bulb that's rather neat. Live mains seems to be occurring more frequently where it shouldn't be in recent videos so merited building a special tester.
Notable shock? You mean blown off your feet landing hard at least until something soild stops You! Then hoping you don't go into cardiac arrhythmia. Love the Scottish no nonsense approach.
Only the Doctor can save you after a run in with a Death Dalek.
that solar panel looks quality....
5:38 That's odd.
3 Nimh cells at 5.04v? unless the USB meter is way off, it means 1,68v per cell and that's extremely high even for a freshly charged cell. Is there a chance that they used primary alkaline cells, making it even more dangerous then it already is?
yeah they're probably charging this thing using alkaline cells!
yeah that voltage indicates alkaline cells, since even fully charged Ni-MH is only about 1.5V - 1.55V each, not almost 1.7V. You can get 1.6V - 1.7V from primary cells such as alkaline or Zinc Carbon.
I love your videos.... your smartassed remarks are wonderful and your electrical knowledge is amazing
... good job mate
I really like these videos about the death-Dalek lights. Please do more, in case you find one of reasonable quality that's electrically sound.
The 2021 versions of these lights are still available for sale on Ebay ( Amazon has the BigClive versions with a USB charging port) though some of them have changed the mains charger to say "DC Charging" or one that has said that the mains charger is a "Micro USB". Sad that this sort of stuff is still being sold.
Some have switched to a USB charging port.
As someone who's connected a device with a capactive dropper to an arduino connected over USB to a desktop PC: fuck capacitve droppers.
Jeez man between your calm voice and it being 1 am for me I have almost fallen asleep like 5 times
Just add one of the tiny step up boards for driving a USB socket from a single lipo cell, then you'll actually get 5v out!
I think a good video would be to modify one of the other ones to safely charge from the mains, keeping all of the features of the original death version except the feature that provides potentially fatal shock.
That would involve a properly isolating transformer, either traditional or switched (smaller, cheaper),
0:55 "iPoons"
Giggity.
1:12 "Not something you want to finger too much"
GIGGITY
3:11 "Let's open up the other end, because that's where the interesting bits are"
*GIGGITY!*
So do death Daleks say E-LEC-TRI-CUTE!! instead of EX-TER-MINATE!! ?
IL-LUM-IN-ATE!!! IL-LUM-IN-ATE!!!
I met a gardener Darlek once. it kept moving around the allotment shouting 'CUL-TIV-ATE, CUL-TIV-ATE. Rescue my siblings'
There is also the bulimic Dalek shouting "RE-GUR-GI-TATE, RE-GUR-GI-TATE" and the one in the skin care shop shouting "EX-FO-LI-ATE, EX-FO-LI-ATE"
The gay Darlek's shouting " EN-TER-MATE, EN-TER-MATE"
@@BillyNoMates1974I'm curious are garden Dalek internally was octopus-like creature? Or this one was more bush like?
you're just a bear on a wire, Clive... (when you're touching those live wires) :)
Clive, that little NiMh/Solar Panel bank you have in you hand at 15:48 is borderline genius, and now I want to build something similar...
is this maybe an elite expeditionary force, dalek probes carrying out recconnaisance before an impending invasion?
In all seriousness, why would they make these things with a mains input if they're too cheap to design it safely? Wouldn't it be just as cheap and low cost for the manufacturers to use have a standard USB client port be it a Micro USB or Mini USB port as the power input so you would just charge it with a standard USB power supply? That would be not only practical but also completely safe on paper at least. I know that people will start making conspiracy theories about it, but apart from that, why would they design the silly thing the way they did?
Because all they care about is getting dollars or sterling etc.; a big part of the Chinese economy is currency manipulation. The "west" is so focused on the short term bottom line that most politicians daren't say so and even fewer will do something about it. As long as we are dumb enough to keep buying cheap crap that's just a facsimile of the real thing, they will continue to make it.
The original dalek light (gold one) used a Schottky diode because it only had 9 sections of solar cell to begin with, so was already down by 0.5V. Therefore the Schottky diode with 9 solar sections gave the same sort of output as these with the standard diodes.
They're basically hoping that you do most of your charging through the mains - along with all of the risks that allows, such as 240V USBs...
I think the designers are missing a marketing 'feature' here.
They should also say it has a magic mains inverter built in*
*= note only works when plugged into the mains
"Big Clive's Laid Back Electronic Scenario" was a trance outfit in Prague back in 1997.
"I like a nice, laid-back electronic scenario."
😂
Alternatively, rip the panel off because who cares about trickle charging them out in the sun, rip out the mains connector, rip out the crappy NiMh cells, drop in a conservative lithium, or an 18650 if you want a baller camp light, and a TP 4056 charge controller. Glue all that crap in with super professional hot glue, and you've fixed it.
Some Chinese products are great. You just have to look over some of them before you use them. I've got a really nice 0-30V 0-5A bench power supply that I use CONSTANTLY from China. Paid $50 for it, even got a deal because eBay had a nice promo code sale thingy. I routinely pin that thing at 5A charging stuff for hours and hours at a time and it's been a champ, though I did replace the obnoxiously loud fan with a nice high flow quiet one. Only thing is the volt meter is .4V off, so when it says 4.6V it's at 5, etc. Yay China.
I almost gave my nephew one of those for Christmas. Glad I got him another kind that doesn't use mains.
So Clive, what's the best way to ensure devices that have USB ports on them aren't lazily slapped on and dangerously unsafe in a world where finding properly listed electronics is increasingly hard due to Amazon. I'm wary about this kind of stuff (thank you by the way) but my sister on the other hand isn't. She actually managed to blow the socket in her bathroom with a really bad curling iron (luckily since it was the bathroom they were GFCI sockets so nothing besides the socket was destroyed. She came out fine as well) and that had knocked a bit of sense into her when it comes to buying new products, but not things she already has. She has a nice little unlabeled power strip, not UL certified (has CE but that doesn't mean much when you can't verify it) which includes two USB ports on it. Whenever they're used, it whines like mad and gets way hotter than I would think it should which makes me doubt the circuitry in it.
If you don't know how to check a device for safety yourself, don't buy stuff on ebay or Amazon, especially if the seller isn't in the EU. Local sellers can't afford to sell dangerous products (but they can still sell crappy ones).
I would like to meet the guy who made the schematics for these..did he make it like that on purpose? oh let me make sure the mains are connected to all the exposed metals lol
I bet the designer was a bullied child and fancied one day getting his revenge on everyone
Maybe 😂
He was trying to wire the ground to the case but he was so pathetic he wired the positive instead
Probably was some farmer that knew very little about electronics that designed it for his uncly that started a factory in his barn or something.
I believe he actually wanted to make something useful for his community. And earn a little money with that. Then he found a book with DIY circuits. But he and his friends and acquaintances didn't knew nothing about safety since their community mentally still live in stone age.
I too like myself a good old laid-back, chill, laissez-fair type a circuit :)) thanks for showing us all this stuff clive, makes for some very nice bed-time viewing indeed
I modified the golden death trap lamp "that exploded" so i could plug a usb micro b to charge the battery and i change the battery to a litium polymer cell with a protection circuit and it works well
Why the heck they can't just stick to mini/micro USB INPUT for charging, no safety isues there...and could be charged with any mobile phone/tablet charger.
Micro USB chargers are likely easier to find around than two pin mains voltage wire&plug...
Two-prong charger cables are cheap.
I decided to invest in one of those solder stations and ended up with one by a company called Mark Ethan. Seems like there are a bunch of ever so slightly different clones available. Really useful for the price though. I love how fast the iron and gun heat up so you don't have to leave it switched on all day in case you need it.
The manufacturer must be watching your videos and going "oh shit, 240V goes to the USB Port... fark" ... surely...
Let start with facts that manufacturer have UA-cam blocked by Great China Firewall and don't know English.
I see JK rowling writing a trilogy about this "BigClive and the Deathly Daleks"
I'll buy one as a Christmas present for that neighbor I don't like
I'm convinced that daleks are ultra beasts collect them all.
The red wires did short briefly to the blue and black wires via the soldering iron. 😀
What would happen if you plugged the USB into the socket on the other side
Ben That would cause a feedback loop in the time-space comtinuum and create a black hole that would suck...
Hadron Collider time
Gay Dalek would prefer Large Hardon Collider...
Illuminating. I have definitely plugged in some USB plugs before and felt a little buzz. I thought I was imagining it. "5V can't shock you," I thought. Now I know.
Even an Apple power supply can give you a tingle. They have a small amount of leakage from the mains side to the output.
+bigclivedotcom what would be an easy and cheap circuitry alteration (for designers) that prevents this tiny leakage ?
Hi Clive. Pretty much watch (nearly) all of your videos :)
I'd be putting the 5ohm up to in the positive side. This would prevent the potential case of the USB in and USB out having a shared ground reference, shorting out the resistor and bypassing both your protection plans and current limiting to LEDS.
You sir, are fkn awesome. Thanks for being dedicated to teaching us on a continual basis BigC.
Hi Clive I found one of these lanterns in my local $2 shop over here in melbourne,victoria, australia and apparently I was told from the shop owner that the charging socket is to charge the lantern via 12v dc like from a car cigarette lighter socket and not for connecting up to 240v ac
you can get a 12v lead with cigarette lighter plug designed for portable 12v fridges that will fit into this lantern.
On these ones it's definitely for an AC supply. It would do virtually nothing on a DC supply as there is a capacitor in series.
Hi Clive .. Merry Christmas and a Happy New Year to you and your family!! Been watching and learning from your posts for a while now .. Thank you .. Keep it up
Clive and AVE.... most interesting people on youtube.
No Username and Cody's lab
Interesting Project & Products There Clive. Keep up the great work. Nick.
@bigclivedotcom
Cloning basic equipment is very common in China; you will see the same case used by multiple manufacturers. In amateur ("ham") radio the Chinese make these VHF-UHF 5w transceivers and various companies share basic cases and sometimes the circuitboards because those radios aren't the big-ticket items (those are the multiband truck radios.) For example, compare the old TYT TH-F8 case to the Baofeng UV-5R and it's the same unit.
Should the USB connection not be isolated from the mains via a double insulated transformer.
Does that mean that Neo was an electron? He returned to the source.
Hi. I'm really interested in the Flir E4 hack. Will you do a video about this? :)
So if you wanted to have this run safely with mains voltage input instead of the USB, would it require a transformer? Just learning here. :P
You could use an isolation transformer, but a proper low voltage charging supply would be safest.
Allright, that makes sense. Thanks for replying and keep making those video's. :D
I think youre a secret Dr Who, building a Dalek empire to take over poundland! However, as an additional Q & A question, have you been round poundland, family bargains or B&M et al, and seen something so bad youve felt you had to warn some bemused member of staff of the dangers of a product, only to have them announce over the tannoy that they need the managers assistance. Cheers Alan
Have you thought of converting one to Lithium Ion? The converter boards are relatively cheap. maybe use a cell phone type battery. might be interesting.
Hey Clive it was suggested in a previous video but you might not have seen it -- if you put a dark red gel over the display on the usb current/voltage meter then it might show up in vids better. It worked for old school calculators and tvs.
I've seen almost the same thing ( it's a Stihl promotional item ) at our local hardware store. It's just battery powered though. Someone must be looking out for us in the states.
I've got the same model heat gun and it's a bit dangerous. The nozzle and the metal surround in the front isn't earthed properly. Mine has just a bit of flimsy wire wrapped around a hole in metal shield. Resistance to mains earth is >1 Ohm. Second funny death trap is the connector on the station. One of its pins is potentially connected directly to live, even when the station is turned off, because the switch only disconnects either live or neutral and not both. Apart from that, it's a useful tool.
What more could you want? a lethal Chinese device and the word "modest". My cup runneth over.
They thought in the 1950's Everyone would have their own jetpack to travel on free energy, wtf went wrong guys.
You could put a second set of oring diodes in to make the charge LED work again....
only other improvement I'd consider doing is adding a boost/buck converter to stabilize the output voltage.
Seems totally safe hahaha :). Your videos are great. Enjoy them. I have been wondering where you get those usb test devices you have? Would be handy in the IT world.
All from Chinese suppliers on eBay. There's a huge range of stuff.
The charger doctor, that is how this one in the video is called, is even available on Amazon and stuff, if you buy from China it is much cheaper though c:
I got 2 things, the charger doctor and one with an extra lead an mAh measuring for capacity tests, the Charger Doctor one seems to be off, some times the voltage just drops when you touch it, or just without any touching. Also does the ampere. But the one with the lead is perfectly fine, but is limited from 0,07A to 3,71A (doesn't show less than 0,07A and 3,71A is the limit shown, even if you put in much more), whilst the Charger Doctor already measured stuff up to 6A despite only being rated for 3A :D (and also measures down to 0,01A pretty precisely, before running out of digits)
There's a huge range of stuff, but only some of it is trying to kill you....
I like the blue Keweisi USB charger doctor things with the inverted LCD because they show voltage, current and mAh all at the same time. the display is nice too
Hello. I really enjoy your videos. and how you present the schematics. I am self taught when it comes to electronics. and can use some advice. or help. I need to parallel several MOSFETs. to switch a few hundred amps. I don't see how the tiny legs on a to220 package get can handle anything near 100 amps. the FETs I was thinking of using is like 80v 150a . I know that's like best case capacity rating. and the real world will be different . can you do a video on paralleling FETs. or reply with some advice. it would be a great help. I wish you all happy holidays. and thanks
I have the feeling that I'm the only mexican that watches BigClive.
E4 thermal camera can be hacked to enable HD sensor.
"No, the button's not live. That's a nice feature" - Big Clive 2016
Replace the USB lead with a USB Micro-B or even just a plain USB B connector and you lose the trailing lead.
How useful is it even, to charge a USB device from NiMh cells? They don't even provide the full 5V. Maybe hack a small powerbank inside is much more useful.
Well, this video was shocking. Shockingly interesting
So the new modified version opens up the option of chaining them... I wonder how many before it breaks :D
Actually, I don't think that chaining these together would break them thanks to the protection diode on the input. A fully charged set of batteries would be around 4.4V, and if used to charge another one, would only be able to charge the cells up to about 3.8V due to the drop of the charging diode, and so the next one in the chain would only charge to 3.2V and so on, and if the last one were plugged back into the 4.4V one as a loop, the protection diode would prevent any current from flowing. Not terribly exciting, sadly.
Since every Dalek in the chain has the reverse flow diode in series, 7 to 12, depending on used diode. Nothing will break though and the last two thirds in the chain won't even charge the batteries.
Clive I seen a video (well 2) on a "pump charger" as we touched on charging here, maybe have a talk and a diagram on one of these style chargers? keep it up!
Stuff like that annoys me... Why would someone produce a product that is complete and utter shit and completely useless...
muh1h1 money
Why would you say it was useless? It plugs in, it charges, then you get light out. That's what it's supposed to do. Dangerous does not equal useless.
Another reason is people like me buy said cheap and unsafe products to upgrade them. Replace everything but the wires and LEDs, (proper power supplies) and a new high capacity battery pack. We make it better. XD
BlackEpyon
They don't exterminate very well, they exterminate extremely well. The user of it, at least.
Ah, a DEATH product! Excellent.
Hmm so one are not going to be able to charge the phone much before the batteries inside are sucked dry. "Novelty product" seems to be fitting.
Clive! The USB port isn't to the USB standard at all! Can you please try putting powerbank circuitry inside one, and a lithium battery? Perhaps put the board from a USB charger on the mains input too.
Funny because we live in the Northern Climate and the fun would be standing in the wet snow and plugging in that usb WOW! Talk about instant warmth. If that dont get your heart going,nothing will. Or Stopped mabe.
Poundland have started selling powerbanks. Would you be able to have a look inside them and see if theyre the same as the poundworld ones
I like your videos because you are saving me a lot of $ that I do not have to spend just to tear into them as well!
These units look really great, apart from the whole death thing.
you really take electrical stuff for granted after watching this.. wow!, especially the El cheapo stuff, holy crap not anymore, interesting stuff clive
what is airgun? 87860 or what? please, anybody. I couldn't hear that
Perhaps add a resistor in line with the switch to reduce the LED current?
