Dangerous DIY Krampus LED foliage lamp.

- Note that this bizarre "lamp" is totally non compliant with most countries electrical safety regulations. The mains voltage version is more of a naughty novelty for those of us with no kids/pets, a liking of the simplicity of the circuitry and the extra zest of its dangerousness.
The video also includes a quick guide to making a much safer USB powered version at the end.
Regular viewers of the channel may get a slight sense of déjà vu as I've made similar lamps in the past in different styles. I've called this one the Krampus lamp as it has a strong Christmas colour theme, but is much less charitable than Santa. It is capable of imparting electric gifts to meddling fingers in the form of electric shocks capable of tossing your body into the air like a ragdoll. That's what makes it special.
To comply with snowflake regulations I have to advise against trying to build the high voltage version of this light. The safe low voltage version is fine though.
It was good to find a source of the little "Molex" terminals on eBay, but less good to find that the contacts are slightly narrower than the ones I normally use. This probably isn't such an issue if they are used in a normal way, but with the use of solid core wire with the rotational tension of the twisting of the wires it may have made the terminals sit at an angle inside. I had an issue with a few LEDs not making good contact initially and that's hard to trace in a long series circuit of about 43 LEDs. Not such a big issue with the USB version as each socket is independent, so finding a rogue connection is easy.
Here's a search link to find the connectors:-
www.ebay.com/s...
The plastic foliage really makes a huge difference to these lights. The stuff I used came from a UK pound shop (The one opposite McDonalds on Sauchiehall St in Glasgow, Scotland.)
You can also buy stuff like this from eBay as artificial foliage:-
www.ebay.com/s...
It turned out really well. The circuitry is simple enough and "low stress" that it should last for a long time. The fact that all the LEDs are ion sockets also allows updating with fresh LEDs at any time with different colours, just fresh new LEDs (they fade over time) or colour changing LEDs. Note that LEDs that flash as part of their sequence will need to be used with the USB powered version.

This also keeps the channel independent of UA-cam's advertising algorithms allowing it to be a bit more dangerous and naughty.

As much as I love the teardown videos, my favorites from Clive are always his projects. It's so relaxing to watch and listen to.
any video of Clives with ' dangerous ' in the title is going to be good
Love these basic project videos, I'm a proper amateur and just enjoy the tear downs generally, but hearing the terms explained and seeing them made and soldered together makes more sense of it all in my head. I'm off to eBay to buy some bits n bobs. More like this please Clive.
The sound is very pleasing in this vid.
Actually, I hear a lot of sound artifacts, like an MP3 with a very low bitrate. It is also in stereo, you do notice it when Clive moves around and unfortunately he mainly comes out of the right speaker; I prefer mono sound to be honest. I never noticed these two things before so it must have to do with the new camera.
@@cannotbeleftblank6027 Sounds very irritating for headphones then. I didn't notice that with normal speakers. Then again my left ear is mostly good for keeping me up at night with the tinnitus.
To be honest, I'd rather it was mono because it suits the way it's filmed. There are definitely audio artifacts that may be built in to the device.
@@bigclivedotcom Try mixing as a stereo video, but with the same content left and right (might require a roundtrip through a sound editing program like Audacity). Alternatively, use a mono-to-stereo adaptor and plugin your lavalier mic into that.
Unfortunately my very first thought after I hit 'Play' was that I can hear a lot of artefacts.
Sound Check on this video is SUPERB """" DO NOT CHANGE """", Your voice moves from left to right smoothly and again SUPERB. Very Sweet Dialect. Love it.
The best videos. Clive just building stuff. So relaxing
Ah, yes, the ungodly extortion racket that is known as "crimping tools of at least adequate quality"...
You get what you pay for, if the seller is reputable. I once spent $75 on some ratcheting Cat cable crimpers from a computer chain store, to make Ethernet cables. At the time (year 2000!), it was about the cost of 3 25' Cat-5e cables. Nearly 20 years later, that same crimper is still in service, having had thousands of Cat-5e, Cat-6(a), STP/UTP, etc. terminations put through it. Cutting blade is still sharp, ratchet mechanism works as well as ever, iron press fingers are still straight. Better to buy the good tool once than the cheap tool over and over and over.....
@@McTroyd yeah works out if you already know that you will put the tool to good use, but if you only dabble in electronics and dont even know which crimper you actually need for your connectors then buying the good ones from the start might be not the best choice.
i would suggest buying cheap tools whenever the need first comes up (at least if its just a spontaneous need) and time will show which actually get used most and then its time to get a better quality one
True for other "pro" tools too. Some are so much better that they justify their price. Others don't . A crimping tool isn't rocket science.
@@raykent3211 Sadly, some cheap things turn out to be excellent quality and some expensive things, crap. Which of the two is the most annoying ?
@@millomweb yeah, the phrase "you get what you pay for" is unreliable. You can pay 20 times as much for a watch that has the same quartz system in it as a cheap one. But with thin gold plating. You can pay 1000 times as much for a less accurate timekeeper hand made in Switzerland. (They really should have kept that CNC milling machine out of shot in their promotional video) if you're in Europe, I'd like to recommend the LIDL "Japanese" pull saw. Very cheap and razor sharp. No DIY place round my way offers anything near it. But statistically, the cheapest things aren't usually as good as the dearer ones. As for crimping, I use a fork I bought in Woolworths 30 years ago. (for pastry, you understand, I don't need one for wires, I have pliers )
Nice project! As for the camera, the sound is great- warm and well-balanced. One thing I noticed at around 16:40, is the appearance of a white line surrounding the dark lines you draw on the off-white paper (and also your hands and your name card at the bottom). The video frame rate also seems to drop (kind of flickery when objects move).
Clive, I just want to say - your videos make me happy. Always just nice to watch and "spend time with you" lol
Thank You! I had no idea why I had to disable Dolby on my Roku to hear the audio on some of your videos!
When I saw you using red LEDs for Christmas it made me think of Holly Berries. Obviously not Holly foliage though.
The simple things can still often be the best.
I didn't think that bridge rectifier was ugly, I liked the look of it with the longer wires before trimming.
I have an Engineers solder sucker with the replaceable see through nozzles which seem to work a lot better at picking up solder than most I have came across.
Really enjoying your "late night 'not in a rush to get to bed' it's weekend!"-diy vids! Keep em coming.
Thanks so much for this very simplified, not TOO technical project. Btw... I have a "bat-tree" operated string of about 50 blinking LEDs (store-bought) that lasts for weeks of evenings on just 3 AA batteries. I'm quite pleased with them. Very safe for kids and still work nicely in our cold winters.
Thanks for the tip on the molex style connectors on the previous video. Bought a few hundred of assorted sizes and they arrived on christmas eve. Save me a fortune over CPC prices for the Leoco branded connectors. I use a generic crimper bought on ebay which works very well on the Molex style connectors in one pass. Doesn't work well on the Dupont style connectors - they require an extra squeeze with a set of pliers.
I had an old computer from the late 1980s that used these same connectors for the front panel LEDs. They put the LED's legs all the way through so they came out the other end where the wires were, bent them around against the plastic housing to keep them in place, then cut the legs off right at the bend. It did a good job of preventing them from accidentally coming loose.
Using classic headphones, I enjoyed the stereo recording very much - gives the audio additional depth and actual deedback whenever you move your head about!
Edit: boi-oi-oing 😁
That looks lovely, Merry Christmas Clive
Merry Crimpmas
Audio has too much hiss when you say "s", like for example on an equaliser, higher frequencies have too much amplification.
Have a Merry for Christmas
Need to talk through pantyhose

Did you add some sort of sharpening filter to the video? Or is there some "sharpness" or "unsharp mask" on the phone camera? There are really strong halos around all the black lines (ex., at 22:10). In fact, image quality in general is significantly worse in this video than previous ones, both in terms of real resolution (looks like upscaled SD) and frame rate (looks like 15~20 fps converted to 30).
Very nice Clive 🎄 Happy Christmas all!
With Dolby Atmos enabled on my Samsung Galaxy Tab and bluetooth headphones your audio was great. When you were moving about I could tell and it was kinda like I was sitting in the room with you. In my opinion with my heavily modified bluetooth headphones audio was fantastic great video bigclive
A pair of these in bare-bulb wall sconces probably looks amazing!
I never was able to crimp properly any connector, until I saw Andreas Spiess video about the IWS-2820 crimper; I bought it for 17 € and... It works ! :D Thanks for sharing and happy holidays !
As about 25% of my job is making custom cables, a pneumatic stripper and hand held crimp that uses the spools of connectors has spoiled me for more manual crimping.
I’d suggest to add a green shrink-wrap over the white LED sockets, to blend them in woth the foliage better.
would also bring the electrocution risk down
Keep doing whatever you're doing with audio, because it's nice and clear in the headphones now. There was a whole stretch of videos where whatever that channel was doing wasn't coming through at all, and it made the volume really low. (Again, I had to cheat to bring the volume up past the "max" to hear those.)
When I first looked a the source of the foliage, all I read was Macdonald's Sauchiehall St. I thought, this is an exciting project.
No Storytime with Clive while he's crimping the crimps on wires? :(
It looks very pleasing. Just like brothel mistletoe.
Next year's could be brothel mistletoe.
Where I used to work in an anodising plant, we used to have expensive titanium jigs and bolts for holding aluminium printing plates while they were dipped in various chemical baths and anodised at 15V. We had some very useful thick rubbery green paint that did an amazing job at protecting the metal while it was in the chemical baths. I had a little pot of it for years, that I used to use in places it was hard to make electrical tape stick. It was amazingly useful, but I never found out what it was called. I've really missed it since the pot itself eventually set.
I wonder if it was plasti dip.
Chance of shock!!! Sign me in! Merry Christmas and happy new year!
I've got a pair of those "why are they so expensive" crimpers (3:10). It does take some practice to get the crimps right. Also helps when the person who runs the wire leaves you enough to work with.
EXCELLENT audio this time, Clive! Mary Xmus!
Again and again I am all impressed by this soldering technique :-) I am working hard on my Big Clive style soldering skills - but still a loooooooooong way to achieve clivish perfection :-)
Cheers for another awesome project Clive! Thoroughly enjoyed watching! :D
I did notice the stereo.Sounded great with headphones.
My crimps are the AMP brand, and the jaws have a step as well. I used them to make up cables in "D" style connectors. Does your green handled ones have this as well? Got their most use years ago when I was making up harness' for a semi-conductor sputtering tool.
I like the stereo. I was aware of you moving your head (turning to left) , before you mentioned the recording in stereo. I used headphones (bad hearing).
I ordered some fans that came with those so I took the pins out to put in a 3 way plug which seem to be the same size.
For "Soddering Beginners" and in Vibrating or moving environments i tend to use the.. whatsemmacallednow in english.. metal crimping shells you use on flex cables if you have the old screw terminals which crush cables...
Put in resistor and wires, clamp it down a bit with your cutter/or propper crimping tool, solder if needed, shrinking tube over and done.
Especially in car door hinges wires tend to break and soldering there will break again shortly.
I also use crimping shells for ultra thin wire, folding back and circling around the insulation, crimping the shell over cable and insulator as strain relief and for bigger clamping are in screwterminals. yes, this won't allow high currents and is not "to standards"* but its better then ripping out cables easily if they get pulled on.
*no gas tight crimped sealing allowing corrosion along the wires.
Since the resistors in the "safe" version are presumably there to limit the current through the LEDs, could you not use a single resistor for all of them? Or would the power dissipation in such a resistor be far too high to be safe?
Using just one resistor would mean that all LEDs would have to be matched to share the current. Using individual resistors would allow a mixture of LED colours and styles.
@@bigclivedotcom Ah, OK, makes sense.
Was coming here to ask the very same question. Never occurred to me to mix and match colors and styles, but of course that'd be nice. Thanks.
While I was watching the part about the usb version, I had an idea which could make construction easier - SIL resistor networks. A 5 commoned network is about half an inch long (13mm) and 5 or 6 of these in parallel (potted in hot melt glue, perhaps) is about the same size and will give a squarish base. A little less soldering and it also means you can just run straight wires to the sockets. There's also just one line of pins to connect to one side of the power supply.
I think it would look good with mixture of green and blue leds
Yeah
And red
Rgb plant
*happy gamer noices*
Blue led's belong in hell.
@@Mentorcase
About 10% of men are red/green color blind. This makes the red and blue LED combination great for indicators.
I have a crimper for that sort of pin that I have used for about 40 years now. It is the simply type with no ratchet and you have to do two operations. There are crimp joints I made with it about 40 years ago still in use.
Regarding your audio it was funny because at the beginning of the video I thought wow his voice is so FM if you will, so soothing and calming definitely smooth and deep and I thought how good it sounded and then as I proceeded in the video then you started to talk about how you changed the recording method anyways this is the way to go! your voice sounds wonderful you should do audio books. it's great audio thanks for what you do.
Hi Clive. The Rapid Electronics tool has the sizes marked in AWG, 24-30 and 18-22 and the other has the corresponding wire diameter in mm. 18AWG=1.0mm, 24AWG=0.5mm and 30AWG=0.25mm
The Hopi meter is no longer flickering as dramatically as it did with this new camera.
Always a joy watching the phenomenally dexterous meat puppets of Big Clive!
I thought there was something strange with my headphones... Indeed it's very noticeable on headphones; it isn't a bad thing either. Gives dynamicity to your work. It means we get the idea when you're trying to frantically look for that Containment Pie Dish.
Wow, that's funny. I had that audio thing where I couldn't hear your voice once before. It turned out to be one set of headphones vs another.. One had a DAC built in, the other didn't.
The audio is quite good. Stereo is a bit weird with headphones bc you are a bit right-heavy. But it's ok.
Greetings from Germany :)
I was watching on my home theater...which I have in 5 channel stereo. I thought I was going nuts and started checking the wire connectors as he was going in and out on the left side.
@@Uneedhelp91 Is there even content with more channels than two?
@@yxcvbnmmnbvcxy544 it just sends stereo to the rear channels.
@@Uneedhelp91 thanks, was just wondering
If one led goes out, they all go out?
Sweet to see you still have your toadstool lamp!
I think that leds often fail short circuit. If so the rest suffer a higher voltage until they all get fried.
@@raykent3211 the video kind of answered this when he took a random one out and they all went out, I just happen to comment as I watch the video
Surely the problem with having lots of LEDs in series is if one fails and goes open circuit, the whole lot goes out, and if it's not immediately obvious which one failed, you might have to test loads of them to find it... Edit: Or indeed if there's just a bad connection as you had!
Best channel on UA-cam by a long way Clive.
Hey Clive. A little late but, marry christmas to you.
I have a question about making negative and positive rectified voltage from a single supply ac transformer. How do I connect the diodes and capacitors to achieve this?
Audioamplifiers do have a centertapped secondary transformer winding for a reason. So I'm thinking if it is even possible to make with a non centertapped transformer? Best regards from a fan in Sweden
If you need a separate positive and negative rail either side of a zero volt rail then you'll need two windings or a centre tapped winding. For low level signals you can get off with creating a midpoint with a simple resistor divider, but for a high current application you'll need a proper power supply.
After all these years of watching Big Clive... I FINALLY get what a capacitive dropper is.
Nice! Gives me the idea of making a led mistle toe. That'd be good since those often goes unnoticed and if you take the time of getting one and hanging it you'd want it to be noticed..
Green heat-shrink over the LED bases would probably be a nice touch.
If you upload a video in stereo but your voice is still “in the center” (having similar volume on both channels) a surround decoder will still put it out through the center channel, it's ultimately the home viewer's responsibility to set their surround decoder up properly.
"home viewers responsibility" ha ha ha.... I've been in customer service for way to many years for that to be a true statement...lol good theory though.When It doesn't work right or sound good it's always somebody else's fault...But thanks I needed a good laugh...
This is the kind of thing you'd see the Electricians make in Northern Light on the last day before the Xmas break. I enjoyed copying them and making something unique
For the Dolby issue, you could try some audio processing during editing, just cut off anything below 200hz.
But his bass is what we love!
There are different crimp tools depending on weather the terminal is designed for a seal to be crimped in at the first set of tabs or just the insulation is crimped in the first tabs
the big thing i like is the bridge rectifier .... our LED string lights here in the US for what ive seen are just in series . no rectification or filtering so the 120v 60hz standard causes a 60hz flicker in the LEDs that absolutely drives me crazy its not totally noticeable but when moving eyes and such it is there and i know what it is and why its there id love to be like johnny apple seed and go around rectifying the strings on everyone's house so the LEDs light the way they should i love LEDs but nowdays there everywhere so now a incandescent light bulb is now special lol with that said Thanks as always for the videos there much appreciated...............cheers to you
Who else here was eagerly waiting for Clive to accidentally touch one of those mains leads while warning us about it?
That's what happens when you watch too many EletroBOOM videos.
I was thinking about making a set of Customizable Christmas lights by chaining these connectors in parallel and hooking them up to USB or any power supply and you could put any colors you like you could even put cable on Christmas tree and than put different colors on any part of Christmas tree. But only "problem" is that each led would need its resistor but tell me what you think of that
Like this? www.bigclive.com/trink.htm
Much more interesting when stuff goes wrong than perfect...as for audio I will have to see after a couple videos. Sounds good so far
Just tried in my livingroom...WOW! Audio is amazing much more clear on my 5.1 system.
The stereo was fine, but the hiss/treble on your voice was pretty distracting. Could be fixed by just popping the audio through a low-pass filter, as the quality was otherwise a-ok! :)
Which moto product are you using? I have an E6 and not impressed with the quality compared to the E5 play...
This was filmed with a G7 power.
Cant say im a fan of the 720p recording Clive, makes it look like one of your early videos (i had to check the upload date to be sure). Sound is good though.
I don't think 720p is the problem, to me it looks like the camera has some ugly sharpening filter built-in...
I love the stereo audio; it sounds much more natural.
I know this has been answered before, however my aging brain has a limit on how long it can recall facts. What value dropper capacitor would you use in our USA 110 volt power?
Double the value of whatever is used for 230V / 240V will get you in the right ball park.
Since the frequency is almost the same, the same value cap would work fine. The only thing that changes is the voltage rating could be lower (160V or so, instead of 400). (Current passed thru a cap is proportional to frequency)
I have used 0.47uF for projects up here in canada, on 110/120V.
Simon Tillson - The frequency is not the issue here. If the capacitor is being used as a current limiter, then if the supply voltage is lower, you need a larger value to get a similar current at the reduced voltage (look up Capacitive reactance). You also need to ensure that the total forward voltage of the LED chain does not get anywhere near the mains voltage, or the LEDs may only light dimly if at all.
@@Mark1024MAK
Frequency does get into it.
Xc = 1 / (2 * PI * F)
In a dropper circuit, you can almost ignore the voltage on the LED and say:
I = V / Xc
Hi I have just bought a pair of these orange crimpers and I was wondering are they any good ?
Sound and image were both excellent with your new gear.
You could isolate the connectors and (lower part of) LED's with clear heatshrink tubing so they would be safe to touch.
Clive, you've made 100's of useful videos...and I've not seen them all, but the power supply part of this was extremely useful! I know the theory of PSU's, but I'm guessing lots of people have never built one themselves! Now where is my soldering iron? :-D
Keep in mind that this is a capacitive dropper and therefore the low voltage is still referenced to the mains.
I'm not a fan of this new camera. I wondered why the picture quality was not right.
Which is the more dangerous, this mains powered lamp or the usb version running off a dodgy Poundworld (no longer in existence) usb wall wart?
I bought some of those connectors a while back and they are fine but, they are not quite compatible with the Molex ones. This became a problem with some projects. I like compatibility over projects, some of which span many years/versions, so I didn't buy anymore. Not worth the hassle. I now remove these from boards when I find them and replace them.
Finaly Big Clive has video of his HOPI, not blinking away.
"Krampus tree that imparts small gifts".......that made my day!
I've found the SN-01BM crimp tools from Banggood to be surprisingly good for "dupont style" and JST connectors (pretty much any crimp that style) .
I'll check that out.
My humble comment would be that maybe spraying the "Molex" connectors light green so that they merge into the foliage might have improved the overall look... But anyway, nice to see you using the bits of dismantled LED lights from previous videos! :-)
You could always wrap the molex connectors in green heat shrink tubing to match the wire colour but the down side it would be safer.
I've had a pair of engineers for a couple of years. As Clive says they do a good job, but if your'e doing bulk they are best done slow and steady. I use a lot of these connectors, where component values are a bit sketchy, being able to quickly try different ones is handy, better than de-soldering. I use 2s and 3s instead of veroboard for cobbling simple stuff together then use the end result as is. Clive's radar/pir mosfet/transistor rig being one.
Bought similar (or same?) pliers for crimping JST-ZH. They worked quite well, no complaints other than I had trouble grabbing and positioning those tiny connectors (abot 1x6mm) and 26AWG wire seems quite thin for my eyesight. Time to invest into microscope or large magnifying glass, I guess.
@@SeersantLoom I have a range of poundland reading glasses .... they all add - so 4+4=8 as 2 pairs of reading glasses is quite manageable even when leaning over work I find that combo covers me for most tasks around a soldering iron (or crimps). Magnifying glass is fine as an angle-poise (they only seem to come in quite modest strengths but in the hand its a liability on a workbench with a soldering iron. As a bonus I did find (SteamPunk EYE LOUPE - DOUBLE MAGNIFIER MAGNIFYING - Clip On Type - Watch Repair" on fleabay
At 3x they clip on the right type of glasses (a decent solid frame).
It's all a bit heath robinson - but it works well enough even on small smd
Awesome video and loving the stereo sound through my headphones *****

@bigclivedotcom: You could thread a piece of string through the spring and tie the ends around each arm/handle, to prevent it from pinging open so much as to lose the spring. And instead of the PVC tube, there's large diameter heat shrink tubing, the kind of stuff that's so wide it goes over battery packs. Green heat shrink might also have helped hide the white on your LED "sockets", which would also have helped shield grubby fingers from the mains.
"To comply with snoflake regulations... " that just made my day :D
Have you made any changes on the sound gear? The sound quality is slightly lower compare to the previous videos.
Edit: I have just watched the entire video and you actually said that you are recording in Stereo. Ignore what I previously said because Im watching the video from a phone with just one speaker and when stereo gets converted to mono it doesnt sound very good...
An Xmas favourite! Just enjoyed it all over again. My wife particularly enjoyed the bit about tossing naughty little boys and girls into the air like rag dolls...
The audio at 49:18 would make a great bass-heavy alert sound for your operating system of choice.
Can someone explain to me which component is making the circuit power limited.
Just guessing here but could the 25 in the KF2510 mean 2.5mm between the terminals? And possibly even the 10 might mean 1.0mm diameter pins?
Or maybe 0.25 inches long and 0.1 inches between pins. The pins are 2.54mm apart.
@@kensmith5694 I doubt it will be in inches seeing as most of the world works in metric, especially in electronics.
@@akc5150
The spacing between the pins on the shown connector is 0.1 inches. It is the Molex KK series The hole spacing on a solderless breadboard is 0.1 inches. The spacing of a dip's pins is 0.1 inches. The pin spacing on an SO-8/SO-14/SO-16 is 0.050 inches. Most electronics is a mixture of systems.
Clive - why in series rather than parallel? Ease of wiring? Parallel would lower the voltage across the LED display and losing one LED wouldn’t kill the whole thing. (I know you know all of that.)
Fior simplicity and extra danger. The safe parallel (USB) version is described at the end.
The only thing that spoils it is the white connectors but you could paint them with green Humbrol model paint or spray them then they would blend in with the greenery but I like it a nice little project my crimp tool is very old now and I remember paying £92.00 for it from RS components many years ago but when crimped you can't get them out it is good
Clive, those look like JYK H2500 family connectors with T2500 crimps. They normally mate with P2500 headers. These are available from Rapid for cheap. Much cheaper than Molex
I usually use the rapid ones.
the audio is a little off center to the right.
a relatively cheap very good crimping tool for those connectors is the iws-3220m around usd $25 on ebay, has very nicely ground jaws and is very close in tool geometry to the molex $$$$$ tool
it's on par with the engineer crimping pliers but it's a one step crimper not a two step pair of pliers
