I love how your projects always come out being really well designed whilst also looking relatively dodgy, really cool lamp though. :)
I'd rather say it's a warm lamp ;)
I'll copy the design and host the gerbers on my github, lets make it last 20 yeas
@@19janiboy96 Do share the link or i form once it is done. It's a very useful project.
I'll either post it here or message Mr.Diode directly
I couldn't hold back my laughter when Grinder and Dremel appeared. I'm currently in the business of designing OEM appliances, but I've never seen a PCB make it like this. Your work inspires everyone.
Does your company have a position for the person who names the appliances? Because that job would be awesome. . What does the appliance do? -it toasts bread. Ok name it toaster.. this one blends food. Name it blender…. This one used microwaves to heat food. Name it microwave.. lol.. best job ever..
@@Z-Ack Most of my work is to design and manufacture PCBs that control kitchen hoods for local Korean companies. If you were expecting Samsung or GE, I'm sorry to disappoint you.
@@minipolenet The world needs little companies too!
When Diodegonewild brings out two buckets of rosin you know it's going to be a good video.
Your soldering method is inspirational, that looks badass man. Hell yeah, pure art. Almost a big "f you" to modern smd soldering challenges. Color turned out great. Also I'd think that the solder should act as a suitable heatsink, keeping the temps even lower.
The key is flux. You want a lot of flux.
I love how everything is drawn on paper and not boring graphs and pictures edited into the video
I love the "lathe" in the thumbnail. :)
That's taken Big Clive's hacked LED bulbs to a new level. I like it a lot!
I half expected it to be described as a 'super sketchy lathe'
That is some badass SMD soldering!! You don’t need a small micro soldering tip, it’s about using what you have and technique. Great job! 👍
And we thought BigClive was the master of cobbling led lamps together, but you my friend take it to a whole new level. Excellent work. 😃😃😃
Cool project. It would be tedious to make many of these, but I like your method of dividing the PCB into grids with a dremel tool and driving it with a capacitive dropper. Many LED bulbs include an adjustable constant-current driver that might also work.
It's difficult to show the resulting light on video as human eyes are so much more adaptable to skewed-spectrum sources, but this orange light is certainly better than sulfur lamps, which have always made my eyes hurt ;). I can tolerate the less efficient mercury bulbs, but not the sulfur ones.
It always amazes me how you approach and do project. It seems so simple yet exceptionally creative. Most people (including me) would just buy a bunch of components and assemble them.
Awesome work man.
Your LED bulb is very similar to the traditional filament bulb, and the power it draws from the grid is very good.
This LED is way more orange.
One of your best videos. So much information packed in. Please do a part 2 with the revised version and make some tweaks. Maybe measure flicker. Make a smooth dimmer too!
I am just waiting anxiously for the DIY Spectrometer, I always want one, but commercial ones are bloody expensive.
I have a $1 diffraction grating, which is basically a toy spectrometer. Definitely not the same, though. DGW has built some good electrical measuring instruments (frequency counter, wattmeter, capacity tester) so the spectrometer is bound to be good.
If you go look at "Les's Lab" on you tube he builds exactly what you want and uses a Raspberry pie and some cheap optics, well worth a look.
"this is going to be dodgy but...." ... That's why we love you man.
"Roxxxxxaaaaaaannne, you don't have to put on that blue-free circadian light tonight."
Really enjoyable project to watch. Tempted to make one of these myself, given my whole house uses 5000K lamps since I like colder light for normal use...
This LED contraption is a thing of beauty...
The light reminds me of high pressure sodium. I guess those would work too if you can find one that isn't grossly overpowered.
Great project, thank you !
Some years ago I purchased a few dozen camera lens filters from ebay. There were many filters that blocked the UV end of the spectrum, some all the way to green "pure green".
Blue Light is not a big issue down here in the Southern Hemisphere.
Anyway, just get a $5 filter, and under volt your lamp.
;)
An LED equivalent of a graphic equaliser would be cool - you could mix your preferred spectrum.
Phillips make them.
I didn't need the lamp to sleep I just listened to you laying down😉😜
DWG great job. Clear explanation of LED spectrum/efficiency. Danieli jste výborný soustružník a výrobce plošňáků. Rád sleduji Vaše videa.
that was probably the best physics lesson I got for ages ;-)
I'm constantly amazed that you still have all of your fingers. 👍😁
Regardless.... I still learn more from your channel than any other. And would gladly trade a finger or two if I could understand electronics as thoroughly as you do
THE BEST PROJECT OF HOMEMADE LAMP
Excellent video again Daniel, and I truly enjoyed your narration. That dry humor is the icing on top 😆
Keep it coming, please!
Danyk soustružníkem, epický!
What a fantastic video! Brilliant project, and not a dodgy winding in sight. Great use of totally inappropriate power tools. I'll look forward to the spectrophotometer video.
Thumbnail image blew my mind, pure genius !!!!! (did not watch yet)
I do not understand everything since I lacked some theory but this is the kind of project I would like to make !
Thank you for sharing !
Beautiful work. Cool project.
Great work DGW!
I like your artistic soldering work
Very good project and great explanation. Thank You.
This is the MVP...the way you explain I like a lot...totally detailed video about light spectrum
This is one of my favorite videos you’ve done. I’d love more of these build projects!
Brilliant Video.
Much simpler - use a filter to remove the blue part of the spectrum from "warm white" LEDs. There are very good filters in some laser safety glasses 😉
i like the cd trick for viewing the spectrum
Many years ago, when I was on active duty with the United States Air Force, I was a technician in a calibration laboratory. (Precision Measurement Equipment Laboratory - PMEL). Because we did all kinds of precision equipment, both physical and electrical, the environment specifications for the work areas were very stringent. Temperature, humidity, and ambient lighting were very tightly controlled. Each year, each PMEL had to be certified, in order to maintain traceability to what was then called The National Bureau of Standards (NBS).
The particular base to which I was assigned could not meet the lighting specifications. There was no money available to completely redo the lighting to conform, but it was discovered that there were some high-intensity fluorescent lamps, which would work in the existing fixtures, at the same power levels as the existing lamps, which would enable us to meet the requirements for light levels. So, we replaced all of the tubes with the high intensity lighting. The only thing was, the light coming from them was intensely green in color.
So, when first entering the work area, everything had a very verdant appearance. However, after our eyes became accustomed (Actually, our brains became accustomed…) Our vision would return to almost normal, and we could see the colors of everything quite acceptably. What a marvelous thing our brains are. Anyway, when leaving the work area, and returning to normal space lighting, or natural sunlight, everything would look red until our brains recalibrated to the more natural lighting. The Lab was split into two areas. One, in which mostly electronic work was done - scopes, signal generators, etc. and the other side where physical standards, and electrical standards were calibrated. There was an air lock which separated the two areas, and also entrance to the outside, where temperature and humidity were only controlled to the requirements of human comfort. There were observation windows between the lab areas and the non-lab area, so that casual visitors could observe without actually entering the lab. When you observed from the outside, the labs looked absolutely green. Looking form the labs to the outside, everything looked red.
Clean build
Wow! You really outdid yourself on the dataviz VFX on this one! 👏
This is so cool!
It reminds me of a Sun in sunset, nice, realy nice.
Awesome build !...cheers.
I made mine with mix of white led and Warm led to give a off white mix..both led can be controlled via knob manually for each parallel strings. Knob is on the led housing and is powered by 4.0v DC.
Its is fully modified just for fun.
Removed capacitor dropper and acid battery.
Added 5v DC from mobile charger port with li-ion and BMS.
Added knobs for 2 individual LED strings.
Added li-ion battery
Added fuse
Added warm white additional strip
Added port USB micro B
When you started to hack out the circle with the Dremel, I thought "uh oh, this is going to look rough". By the end it looked like a professional prototype!
Brilliant brain you have!
Very impressive!
Super interesting!
your soldering skills always manage to impress me. I am now confident to put together a ~200 smd led clock kit from aliexpress i ordered :)))
Wow I wish i have an uncle like you.
CD reflection was a great test of spectrum!
Well done!
wow, you went all out
Love it. Ruler from powerbank, 90° from pcb,45° from folded paper 😂😂😂 my hero
Only genius will find his way through chaos.
Your light looks very pleasant. I look forward to the DIY spectrometer.
Ive made a similar lamp e14 base lamp using 1 watt red, deep red, yellow and orange leds and a capacitive dropper which passes 70-80 mA and power of 2-2.5 watt which produces orange-red light with very little blue. I am using as a desk lamp it is a bit dim but it is not disturbing my sleep pattern.
i enjoyed this even with all the dodgey stuff as you have to get it done no matter what
You are amazing!
I love it
Cool project & a great implementation using easy-to-get tools! By coincidence I just finished an SSTC based on your IR2153 design, and am currently working on a DIY spectrometer too!
Good luck! 👍
niiiiceeee.
btw., I REALLY have to remember this one @6:44 lol
Very professional and knowledgeable! But at 17:05 we see the most beautiful electric light: that of an incandescent lamp, the only artificial electric light with natural and full red spectrum content.
It looks like sunset.
Genius idea to use a CD as a diffraction grating!
Nice!
I love how he keeps drawing everything instead of using a printer
Great build! I want to get a full red alert mode lamp, a car brake led lamp I have used for this before. 😎👍❤️
You can't use leaded tin and leave the RoHS marking on the lamp. :-D
The original Chinese board I removed from it was just as RoHS ;)
Thanks!
Thank you ;)
You could save a lot of aggravation by just getting 2200K PCA (phosphor-converted amber) LEDs, for a much smoother spectrum with very little blue content.
2200K is equivalent to candle-light, very easy to look at, and with better color-rendition than several "spike" emissions of red, green, etc.
Thanks
Only legends can make those
Man, it's tough to decipher your powerful accent! Very interesting and genius work though.
Like a neon glow tube.
The circadian blue issue depends on where the light is in the field of view. Low is OK, high is bad. Also adding some near IR into the mix will improve cellular melatonin production.
Please build a diy spectrometer... That would be a very interesting project I guess
Go to "Les's Lab" on you tube.
So interesting and a nice looking lamp. I must admit though I'm a little bit skeptical about things like light affecting your sleep. Maybe because I'm one of the people that it doesn't really bother. I sit out here watching TH-cam videos before bed. Then I go lay in bed, close my eyes and 10 to 15 minutes later I'm out like a light. In the winter time I sit out here in the evenings drinking black tea as well and go in and go to sleep. Really the only time I have a hard time falling asleep is in the spring when we crazy people in the United States push our clocks forward an hour. Trying to go to sleep an hour earlier than you have been for 6 months just doesn't quite feel right to the ole brain.
Great
to solder SMD u need xD... just get a propane torch an blast it like soldering copper pipes
insanly interesting Video 👍
Basically, it's like replicating the light output of a low-pressure sodium streetlamp, the yellowy kind that starts off red when cold, I made a light that used 3x sodium-yellow 1-watt "bead" LEDs and it makes for a nice imitation of a streetlight's glow, not that I use it much cos at night I like it dark when I sleep... :P
Low pressure sodium lamp would be great for this purpose. High Pressure sodioum lamp too.
Bloody hey ❤️
DIY spectrometer, next video, PLEASE!
I used to have the exact same Soviet soldering gun
I found this one strange, vintage LED that was a green LED diode inside an amber translucent resin, it was used as a light for a telescope eyepiece case.
9:05
Nothing cleans rosin better than the wife's toothbrush.
Just make sure to put it back before she gets home
Nice construction of sleep lamp, and a good use for that big enclosure. Though for a more efficient lamp, with less attention to removing the blue light output, I'd probably use the pure geen LEDs as they are brighter and more efficient.
Also, I wonder, how many lumens does this produce (what is it equivalent to in terms of brightness)?
Also, for soldering SMD, most people use a hot air station, not a huge soldering gun with tons of rosin and solder.
I've seen phosphor red LED's also, maybe they're worth to look at them
Love this video, I wonder if you take a normal led bulb and replace the leds with the one you used? that seems more feasible for people like me thank you!
Genial
19:08 this light color reminds me of the 'high/low pressure sodium lamps' there used to be in the streets lights during night (and might still exist at some places) they also had orangey color
Exactly. High pressure sodium lamps emit ~590 nm almost monochromatic yellow/orange light.
And the color rendering index is quite low, similar to his homemade LED light.
Of course, his homemade light has a better CRI as it is comprised of red and greenish LEDs.
@@imnotbeluga007 No, his home made LED lamp has better CRI.
High pressure sodium is only 590 nm. I have many of these and it's really monochromatic light so you can't see any other colors.
@@Ni5ei Yeah. Tried cubing under a street light, and.. it was not easy. All the colors except white/yellow were black or gray, and white/yellow was dull yellow.
@@Ni5ei High pressure sodium is NOT monochromatic. Do not confuse it with low pressure sodium lamps.
@@imnotbeluga007 HPS/SON is not monochromatic. You probably went under a LPS/SOX lamp.
8:59 A drinkable fire extinguisher
Really interesting video, liked your pcb/dremel skills. Ideally, to copy the design we would need to know which leds you bought and/or which supplier.
I will put the typenumbers in the description...
👍👍
Danyk, would you make a video about capacitive dropper psu? How to construct 'em in a *right* way, how to calculate etc..
imho It would be helpful..
The wavelenght looks like HPS or LPS lights, which is 589 nm.
Those diagrams are very good,
What if you used crayons to better display you're inner nature 😅
I wonder if back in the old days of tungsten bulbs, people had difficulty with their sleep as they do today?
I have a 60W old school lamp in my office but LED everywhere else in the house.
My monitor is a BenQ GW2760S that has "Senseye" blue light killer.
I fall asleep before my head hits the pillow :)
