- Yet another grey import shipped with an unsuitable power supply, made somewhat worse by the conductive metal parts and target market of children.
I'd like to thank Ray for sending this ornament. He'd received it as a gift, but didn't enjoy the experience of getting shocks from it. The leakage current was low, but still enough to give a very strong zap. Especially when handled while your body was referenced to earth/ground.
The non-polarised LED blocks have simple but clever circuitry, and an equally clever connection system to allow very fast manufacture.
If you have one of these with the non-compliant power supply, I recommend splicing on a chopped USB cable and only using it with a good quality branded power supply from a known source. (Like IKEA, ASDA, Walmart and other retailers that need to protect their reputation.)

“A strange game. The only winning move is not to play.” If you line up the blocks just right, the line does not get eliminated, you do.
Why am I not *even in the slightest bit* surprised about Clive being all excited about playing with something that gives mains-voltage zaps?
The more it zaps the beter it is
Channeling some ElectroBoom 😂
@@thecatofnineswordsNot completely, no sparks today.
Every zap increases Clive's beard strength
@@Can0spamhe should be renamed Samson
In some computer game museums, saw one in Berlin and Paderborn, they have a "pain station" novelty arcade thing, which gives shocks to whoever loses. This can perhaps be considered a home console version of that.
There's a James Bond film with a game like that. I forget which one.
@@zh84 Never Say Never Again
I remember in my home town there was this Addams Family game in our movie theater that I assumed was like this. Never tried it but was super curious.
@@HandyFox333Those things have been around for a very long time under different branding.
When I was a child in the late 1950s a neighbor who repaired TV sets showed me how to estimate the CRT’s second anode voltage by placing your right elbow on the grounded chassis and bringing your fingertip near the rubber anode cap. The longer the arc, the greater the voltage. That, and some other random line voltage jolts were enough to later permit short, skinny glasses-wearing me to take far more than anyone in my High School including the big macho football team captain on one of those machines at a summer carnival.
I was already considered a weirdo, that just cemented my reputation. I didn’t mind a bit.😅
I remember those! for some unfathomable reason they seem to have got rid of them
I have an isolation transformer that I use to do "live" testing. I now find it very handy when trying out any mains powered Chinesium gadgets.
Yes, it's always best NOT to connect yourself to directly to the National ☇ Grid via a piece of cheap Chinese sh1t! 👍😂
A tetris game that shocks you more as the screen fills up - that could make an interesting project...
It would be interesting to see if that could improve a player's performance and long term skill.
I like the way the PTC is labeled on the screenprint with "r1" and a capacitor symbol.
Tingle-tastic Taser Tetris!
ASMR will never be the same ...
I find it fun to turn every 5vdc device w barrel plugs into 5vdc w usb plugs. My fish tank had one 5vdc brick for a tank heater and one brick for the tank light and now it has two usb ends and a single dbl usb plug. Limiting all the bricks I’ve got to plug in makes me stupid happy. It really is the simple things in life that give you the most joy. I also hacked a laptop PSU (don’t worry I remounted it to a new box) to run an array of 12V devices around my desk.
i've always been rubbish with tetris. but if the designer had "INTENDED" to give you a zap when you got it wrong,,, it would be a stroke of genius and significant learning aid 🙂. Cheers BC.
I regularly get tingles from laptops hooked up to chargers when touching the case with the delicate skin of my inner forearms. Big brand names as well.
THAT'S A FEATURE..... NOT A BUG!!...... Keep up the good work Clive..... Love your stuff!
I bought one of these many years ago, but I hardly used it because the flicker was *horrible* - some of the most egregious illumination I've ever witnessed. You inspired me to disassemble it and now I know why. Mine deals with the unknown polarity of the blocks by using (5V) AC rather than DC. And each PCB (not just in the base block but in all of them) only has *one* LED. So at best each end of each block is flashing alternately, but at worst they're oriented the same way and each block is spending more time off than on in each cycle - which I think better matches what it looks like. The pads and silkscreening are there for the second LED, but someone obviously decided to cut costs. With that in mind I think I'd better test the PSU that came with it as well!
Over the years I have wondered about trying to smooth it out with capacitors or something, but adding those second LEDs and running it from USB 5VDC is probably a much better plan!
The Egregious Illuminations start in Blackpool soon! 😂
I had enough electronics knowledge to put a supercapacitor and a bit more weight in each one, but not enough to know that they could have been a bit zappy. They did work much better, though... 😊
I never quite decided whether I regretted spending far more time on these than their child owner ever did.
I'd have pulled the blue capacitor out and then test again- To determine the source of the mains leak.
I was really looking forward to the HV "burn setting" test. My favourite Big Clive electrical test gear. Mini "photonic induction" destructothon. 👍🏻😀
I'm pining for the days when manufacturers used isolation transformers.
There is nothing inherently safe about any transformer. They only use the cheap fire/shock hazard SMPS in this cheap uncertified crap because it's cheaper to build than a cheap fire/shock hazard power transformer.
Technically this was an isolation transformer, wasn't it?
😂 now most products don't even get QC
@@adamdnewman There is QC, the tesater plugs it in, if the lights do not go out, and it sort of works, they stick the QC sticker on. If lights go out, reset breaker, and still put the sticker on.
@@SeanBZA ☺
Jeeez Clive - I love your videos - I know absolutely nothing about electronics (plumber here) and have zero interest in electronics - That should be testament enough to the quality of your content.
I had a set of this from Think Geek over a decade ago. Being in the US the power supply was obviously different and I never got a tingle from it but it was no better about contact by the various blocks.
Yeah mine didn't seem to have any issue. It did work alright for me on a shelf except that it could always be knocked down
Probably been copied, much cheaper
Damn, this is a shockingly simple Tetris ....!!! Great work.
Aside from the obvious (or not so obvious to some) danger, it looks like a cool decorative piece!
I feel like the whole thing could benefit from a makeover and some magnets--to snap the pieces together and complete the circuit 😅
I got one of these sets a long time ago back when ThinkGeek still had physical stores. I think the interesting thing is that mine did actually come with a USB lead with a straight DC barrel plug instead of this right angle mains one.
God damn floating neutrals. Got me so many times.
I have two sets of these running together. They never worked well just sitting up against each other - at best, they were very flickery and the voltage drop across it meant that the side farther from the power supply was noticeably dimmer. I ended up hot-glueing the thing together, shimming the contacts between pieces with little metal wedges, and manually wiring it so the power is distributed more evenly.
Also, the NA version came with a USB power supply and a USB to barrel plug cable.
If you added some little magnets and iron chunks to the blocks I wonder if you could make one that didn't suck. Higher voltage might help reduce the current draw and dimness as you get further away.
Could be a cool toy to mod with brighter LED and more shock protection. Turn it into a design thing in a room.
Would be nice if the two LEDs in each block were different colors so that flipping the block would give a different look.
Usually they are brighter and meant for a cozy illumination.
Just use them with a decent pier supply. And then one can stack them.
As with all chinesium devices there are probably some higher and lowe quality versions of that
I remember having one of those when I was much younger, and getting a few zings off it
I knew exactly what shape the charger would be, before I saw it. Those shaped ones are often dodgy.
This reminds me of this Addam's family arcade game where you hold two metal handles and it shocks you and the shocking gets stronger as the game goes on and lights light up and if you hold on long enough and the lights reach the top it sounds an alarm and blows smoke meaning you've won the game. It doesn't actually shock you just vibrates the handles but the game senses when you let go. I guess it detects the impedance of a person and knows if you let go.
Some would say the zaps are part of the fun
I like the toy! I am going to see where you can get them. Great birthday present (for the right person)
I've seen these before, and in fact, I have one of these Tetris lights myself! I also agree that it's quite hard to get a good contact between the blocks, and mine also seems to get dimmer the further up you build.
Thankfully mine hasn't shocked me yet... I don't think it has a dodgy PSU, but we'll have to see!
In the (very) past I got a number if Zapp‘s by listening to a weird bearded American lute player.
Ok, also got some from AC mains and more 😂
I got one of these in a charity shop for 2 quid a year ago. Its still in the box. Took one look at the power adaptor and thought.... save it for another time..... 🙂
It's probably mine! ... I gave it away, because it was cr*p! 😂
the entire time of the video the 'Tetris' song is playing in my head.
ooh boy am I damaged. too much Tetris
My brother had a version of this as a kid. Luckily I think ours had a better power supply because I don't remember any shocks and we used to mess with it a lot while it was on.
I bought this lamp when it first came out many years ago but I couldn't cope with the constant flickering in my peripheral vision so I never switched it on, and I'm glad I didn't now! I eventually sold it to some unlucky person 🤣🤣
I'd never heard of the Zappy and Tingly Toy Company before... oh wait....8^) On a serious note though, I can't believe that non compliant PS's with electric shock risks are still made and sold.
One word. China
Oh nice, Clive doing a video on a thing I have one of (which I also got as a gift, and which I am always very concerned about because its construction makes it pretty obvious how dangerous it is). The "manual" which came with it gives you pretty dire warnings about not laying the blocks across the metal strips.
That's nice, I love when cheap PSUs make exposed metal tingly. I had a HP laptop once where the metal chassis was tingly like that. Fun times
That was Y capacitors most likely. Not dangerous but definitely annoying.
i have had a couple of Vestels give me painful shocks, but my houses 1970s wiring has awful grounding so i get shocked off loads of stuff like my Macbooks and Dell XPS L702X
Oh! I was wondering what that was when I touched some old laptops with shoddy chinese chargers. Dear god.
@@lainamitclaire Dear God indeed good sir
imp mentation
Talking of shocks I got one hell of a belt, off a desk fan from Amazon. The other half bought it direct from Amazon. It sort of moved a bit then stopped so he switched it off and on a few times, no joy. So he asked m to check the fuse. So I grabbed the plug after being off for an hour and got the worst shock I've had in 20 years.⚡⚡
The perfect shocking stuffer, er I mean stocking stuffer!
Some will say "It is fun playing with it, because of the zap zap". Others pay for such an experience .... I heard ...
I’ve had one of these for over a decade now and it gives a really soothing light, but I think the Canadian/US ones have a better power supply. The wire’s much thicker on mine. Still makes me want to test it now, even though I’ve never had an issue!
If I may make so bold, your smile is very attractive, in your little round photo! And I feel sure Big Clive, and his beard, would agree! ... I'm glad you weren't electrocuted ☇ by your Tetris light! 😂
I thought for sure you were going to say the way to make this a safer plaything is to carry it over to the bin and drop it in.
I thought about getting one of these as an ornament but the unevenness of the light put me off. Now I can see why they're so bad! Can imagine that the contacts would tarnish quite easily making the whole thing bin-able in a short time...
They do. The metal on mine has tarnished and it never really got a good connection even when new.
Can confirm, good idea but bad execution
@@ermfwpthe execution comes via electrocution... 😁
I can confirm, they're total cr*p! ... Except if you're blind or partially sighted, in which case, they're brilliant! (Because you can't see how cr*p they are!)
Now, the shock could be part of the game when you get it wrong 8-).
Now to go duck and hide from Clive's flying "vice of knowledge."
Looks ripe for replacing the LEDs inside with say 12V LED tape all around the inside perimeter, plus a rectifier instead of diodes in inverse parallel. Should be much more evenly lit, brighter and with the larger voltage may be less flickery when moved about.
Might give it a go, seems like a fun project.
I've got one of these! The zap is a little tingly but the effect of the lighting is cool
You've got to stand barefoot in salt water and handle it with sweaty hands. 😊
keep the Zappy and tingly feeling make it have a consequence for moving my setup
Awesome Video Big Clive
I am impressed, I have expected a dropper. You will be surprised how many dropper supplies I meet every week.
With how ubiquitous these have become in youtuber backdrops, I'm surprised it took Clive this long to rip one to bits.
While lying in bed one time with my phone in my hand and my laptop in front of me I remember getting this distinct painful feeling from my arm, like a hair was caught in the plastic framing. Both laptop and phone were charging, and I eventually worked out there was a significant potential between the aluminium phone chassis (connected to the phone charger ground) and the exposed headphone jack ground (connected to the laptop charger ground). Quite odd; The charger was a genuine Samsung charger and the laptop charger was made by a reputable OEM too. But clearly one of them had bad isolation, and considering the laptop charger has a ground pin I'm inclined to think the phone charger was at fault.
For a while, when WFH became really popular for no apparent reason in early 2020, I had a Mac Pro with one of those aluminum wired USB keyboards, and all of my work stuff was on my MacBook, also aluminum, powered from its own DC supply. The USB keyboard was right in front of the laptop, so if I touched the keyboard's shell with my palms while touching the MacBook, I would get a little tingle in my wrists.
At first, I thought it was just the sharp corner edge poking my wrist, but it didn't matter how lightly I touched it, it still felt like a sharp poke!
After a while, I would just do it for grins. I think there might be something wrong with me. haha
so it literally makes its own case live, by design
souvenirs , novelties , party tricks
I have one of those... that power supply (or at least the europlug version) also makes a very unpleasant high pitched noise, which is why I usually switched it off with a button on an extension cord, to avoid having to listen to that noise at night.
I'll have to think about that mod you suggested, though I'll probably have to watch some tutorials about splicing USB cables or something.
There are brighter versions.
They are nice to illuminate your room or for decoration.
"...and the better option that you likely have already all around your house only provides HALF of mains voltage at only 125 microamps." Anyway, looks like I need to settle down with all of my USB chargers and a multimeter and see what insanity I've been unknowingly-using all along.
We had one of those plasma ball exhibits it must have been 50cm diameter mounted on a cylindrical I assume laminated board plinth with a flange edged with a wood moulding. Visitors would stand their children on a wooden stool and let them drape over the globe and then complain when the static discharged to earth through the adult by an arc on a point contact (“It burnt my child’s arm!”) when they proceeded to lift the child down. The exhibit got sent back to the builder who said there was nothing wrong with it, as the floor staff tried to tell them, but they insisted and asked for the power to be reduced, which made no difference to the outcome. A great exhibit that needed just a small sign or even metal stools at the location was eventually taken off the floor never to see the light of day again. Edit: I encouraged a teacher to kneel on a stool and place his hands on the globe, then said to the nearest 16 year old pupil, Touch his neck. He was not happy, but the lesson is, use your f-ing brain.
Sometimes I accidentally click on another TH-camr who does this format of videos. I'm always a little disappointed with my misclick. Thanks for making quality videos.
Big Clive's definitely not a "misclick!" 😂
@9:33 - I most defiantly can feel the tingle when charging my older iPad with a legit Apple charging block.
I would say that placing 3 AA or AAA batteries inside "input" block will make toy better. Cheapo 3 batery case and 10 minutes with soldering iron will make for wireless experience.
I have had one of these for a few years now. Its a lamp not a toy. And never once got a shock from it. First time I've not agreed with one of your videos. I still enjoyed the video though.
I've got one of these, somewhere in a moving box. I was going to have to ditch the UK PSU for an EU one anyway. You can get USB to barrel plug cables for very little money, which would make a lot more sense.
I converted mine to USB ages ago, but not due to Clive's leakage issue. I suspected a proper 5V supply would make it work better (when you walk past the bench it was on the lights would flicker as the connections slightly moved). I was correct. Running off an old Samsung USB charger now for years.
I had one of these from amazon and the power supply exploded in the socket and shot across the room!
I have this exact one! Exciting.
Thanks Clive.
Clive - cast your mind back to the vcr days, I always remember getting "half mains" tingles from touching a known earth then running an exposed body part like arm or backs of fingers over the painted case of a metal device like a vcr/dvd/cable box. Unique... Could you explain that?
Also used to love turning on crt tvs, with hand on screen, collect the charge and zap my 2nd help helper when he wasn't looking 😂
It's the exact same thing. The interference suppression capacitor in the switch-mode power supply is wired between something on the mains side of the supply (often the negative of the input rectifier) and the circuit ground. Without this capacitor the power supply creates _tons_ of RF interference which besides being illegal would result in a noisy video signal in the analog VCR, or reception problems in the cable box.
The small “leakage” current flowing via the class Y interference suppression capacitor (in the switch mode power supply unit in the TV/VCR/DVD/Sky Box/Set Top Box) to earth via *YOU* …
In the 80s I had a TRS-80 with joysticks that always felt tingly.
Should have tried breaking off the capacitor between primary and secondary to see if it solves the problem. (Note to cheap PSU makers: if you can't be bothered to use proper Y rated capacitors between primary and secondary, don't use any at all.)
That's funny. Try this: Ditch the 5V DC switcher supply altogether, use a 6.3VAC wall transformer, 5Watts. Now you'll get both LEDS to light (alternating) on each board, although with a slight flicker.
I've had one of these as a bedside light for a couple of years. It's pretty rare I get a tingle off of it and it all still works well.
That doesnt make it safe.
Get rid of it! I had this exact device as a present from amazon, the plug EXPLODED and SHOT across the room! Lucky it didnt burn my house down!!
Toy might be fine...plugtop psu are "very variable " in quality...
"Baby becomes live" once again.
Dangerous toys for girls and for boys .It's the electricution toy it's fun for a girl or a boy !
Oh boy! That tickles! ⚡🥴
They might as well had made a *_mains voltage_* version 😵
"Super dodgey! ☠️" -diodes gone wild
I have one of these, I haven't used it in quite some time. I believe mine once did give me a zap, I think that was partly because my fingers were a bit wet. I like these Tetris lights, mine worked well, but you've got to make sure the contacts are making a good connection or the blocks don't illuminate. You're quite right about the flicker, it really does flicker quite a bit.
Oh, and how did you come to have "wet" fingers? ... Or should I not ask? 😂
@@marcse7en I'd probably been washing my hands prior to handling the unit and mightn't have dried them well enough.
@@Lachlant1984 A likely story! ... But I'll believe you! 🤣
I got my kids 4 sets, so they can play a big ol' game of Tetris. I like to think I have half a brain (and certainly enough to know that cheap Chinese power supplies are awful) I run them from a USB power bank.
If you happen to have any old e-cig batteries laying around and don't mind a bit of polarity, you can pop one inside the blue brick along with a little charge circuit for portable fun!
Be cautious about using a lithium cell without some form of short circuit protection.
I bought a couple of sets of these -- it seems the 110V type sold to US customers is less zappy than the UK version.
My objective is to build a permanent display for these, powered from a 5VDC switching supply.
I have one of these and the base unit went caput. Perhaps it was the charger. Maybe I got off lightly (no pun intended). These were sold in legitimate gadget stores. You may have started something here.
That's scary. I've got one of these from years ago, but don't remember ever getting any tingles.
Perhaps you've got a bad memory? 😂
@@marcse7en I do!
Hero BigClive has two main goals in life : carbonating and saving lives but both goals are not related. See you soon.
I suppose the advantage of the old style transformer based wall power supplies was that by their very nature, the output was isolated from the mains.
Proper transformer, proper construction, design and materials. Not a MMS (Micro Minimalist Shocker).😏
With the exception of the (hopefully) class Y capacitor switching adapters are still isolated by a transformer. It's just a question of how much they cheaped out on said transformer. Most I've seen have a two-section plastic bobbin which will provide lots of separation but sometimes the windings were also done on top of each other. That's the same level of separation as most switching adapters, all coming down to the wire insulation and any layers of transformer tape.
Only if it is well build.
I have seen horrible transformers with no insulation between the windings.
Well, it'd stop kids touching it at least... :P
I received a pop up advert for a fake fuel saver after this post
this feels like an 80s children toy before we established some manner of safety standard to shiny new technology
Considering a woman died from a fake phone charger a while ago I would only use one from a known company that makes quality power supplies or just use batteries.
I've been shocked by 110v mains enough times to know it's never fun. Even a shock from static electricity can also not be fun as I've mentioned in a comment from another Big Clive video.
I had one of these, corners would always tingle
But... I like the tingles!
Speaking of leakage current, a while back I grabbed a random old jug plug power cable and was surprised when the device didn't power on. I thought it was broken and went to disconnect the power lead, but noticed a weird tingle when I touched the enclosure. I immediately disconnected the lead from the power board and checked the continuity and got nothing on the live pin. Plugged it back in and checked the voltage, nothing between live and neutral, but I was getting ~120V between ground and neutral! Didn't think of checking the leakage current, I just grabbed another lead and moved on.
Later that night I decided to do some troubleshooting, so I grabbed my Stanley knife and went at the plug. Turns out the live pin was terminated so poorly that almost all the strands had been torn, and one of those strands was very close to the ground terminal in the plastic moulding. Evidently at some stage the final strands on the live had flexed and snapped, so that's what caused it to stop working. The fact that the live wire was
I once had a jug cord that shorted internally and ruptured out the side of the cable. Quite exciting!
I bought some of these thinking they looked cool, when I got it, saw the quality and found out how it worked I plugged it in once and then put it in the drawer forever more ...
Hey Big Clive, I received one of those Tetris light things too, as a Christmas present from my sister-in-law! ... I don't know what I did to upset her, because it was crap! 👎😠 ... I'm not bloody 5 any more! 🤣
EDIT: It's funny you should mention Tetris electric ⚡ shocks! ... Because I received one from mine, and sadly it killed me! ... Fortunately, they managed to resuscitate me, and I can laugh about it now! 🤣
My electric rat killer (kills electric rats!) has a power adaptor just like the Tetris one! ... Nice and dangerous for the vermin!
So, should I not be using cheap Chinese power supplies with my s** toys? ... Oh God, I've done it again! Typed out loud what I'm thinking, and embarrassed myself! 😲
My first thought? Earthing one of the low voltage leads would have fixed the problem and they already have a plastic pin on the plug.
The other thing you could do is lean into the tingly zappy and set it up on your desk and invite your annoying coworkers to play with it... I'm sure that when you're called into HR that you can explain that Big Clive suggested a different power supply but you hadn't gotten around to it just yet... You were too busy watching ElectroBoom videos.
wait I have this somewhere. and it sure did zap my fingers a few times and i had to put it away as a result. i like how it could be rearranged though.
Tetris meets Milgram Experiment! Play the game, and if you miss a move, you get zapped by the white labcoat!
Nice to see the CE mark on the power supply, but would it pass or is that a fake sticker?
The CE mark isn't always to signify what we know the CE mark to mean. Ages ago I remember seeing a video about how slightly different spacing or fonts would be used because the mark, essentially, was a 'Chinese Export' or 'China Engineered' mark that just 'accidentally looked almost identical' to the CE approval mark. Sneaky behaviour!
@@GothBoyUK very sneaky!
Clive, what are you using for labeling these days? I got one of them brother cubes and am really surprised with how good they are for the price
Never heard of a Brother cube label printer but I have one that looks like a small typewrite with LCD display for what you're going to print and LOVE it! Take a look at just how clever the labels themselves are. th-cam.com/video/W2SRePOg4VM/w-d-xo.html
BC did this a while ago th-cam.com/video/W2SRePOg4VM/w-d-xo.html just don't go for a modern Dymo as they added DRM to the label cartridges. Classic Dymo is much better.
Still using the label printer I reviewed.
It's possible that not all the AC adaptors included with the unit are the same, mine came with an Australian power supply, that is the prongs on it were configured for our power points and there was not need to use a converter. I may even have a USB cable with a barrel connector on the other end, my HDMI switcher came with such a cable.
If the feedback coil is between the primary and secondary, would it help to ground one end of it to reduce or eliminate capacitive coupling to the secondary? Alternatively, have a layer of grounded foil between them.
Well they could supply rubber gloves with it, or run it on a battery pack maybe.
Anything that contains that goddamned decoupling "Y" capacitor (which all mains power supplies do) will connect you directly to mains AC (and therefore shock you) in any country with a non-polarized mains plug with a 50% probability, even if it's just a USB charger.
Half true, it will connect you to the AC line through a capacitor, and the capacitor limits the current to a safe value. In the old days here in the US they'd often use a .05uF capacitor on old tube radios which would pass 2.26 mA, almost five times today's maximum permissible value. Worse it would be a paper capacitor which becomes leaky with time and lets even more current through, I've found one that was a dead short.
@@eDoc2020 safe yes, most likely. However, it still tingles under the wrong conditions, which I positively hate even if it almost certainly won't kill me.
Most PSU designs i've seen the capacitor is after the rectifier, so it doesn't matter which way round they are plugged in.
