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.
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 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.
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!
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.
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.
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.
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.
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
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. ;)
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.
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!
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...
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
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.
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.
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.
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.
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.
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!
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.
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 RUclips 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.
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
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.
Where do orange LEDs fall on the spectrum and how are they in terms of efficiency? I would guess they are not very efficient because the current demand for blue in general lighting and RGB in (O)LED screens drives research efforts elsewhere. Also, how about alternatives like neon glow lamps and other gas discharge lamps - what is their spectrum and efficiency? Are high-pressure sodium lamps, as impractical as they are, usable in these bulbs?
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 :)
I wonder if you could program smart bulbs to adjust their color temperature to the time of day, or sunset times? Like mid-day it would be the normal full spectrum at 4000K or so. But after sunset, their color is shifted slowly towards yellow.
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!
I love how everything is drawn on paper and not boring graphs and pictures edited into the video
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.

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! 👍

I love the "lathe" in the thumbnail. :)

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.
Excellent video again Daniel, and I truly enjoyed your narration. That dry humor is the icing on top 😆
Keep it coming, please!
THE BEST PROJECT OF HOMEMADE LAMP

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.
An LED equivalent of a graphic equaliser would be cool - you could mix your preferred spectrum.
Phillips make them.

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 😉

What about placing a yellow glass filter to block the blue light entirely?
Hey, can you check out some of those really cheap GaN chargers? like the ones that cost like 5-10usd
Very impressive!
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...
Good luck! 👍
Very cool lamp!! Can you measure the light intensity (lumen) ?
Does the light from a screen cross the ~470 nm center carrier wavelength that triggers our circadian response?
I use BLUE night lamp and I can sleep completely fine
