DIY SMD Wireless LED Lights: Better than Store-Bought?
HTML-код
- Опубликовано: 26 дек 2021
- SMD wireless LEDs - what's not to like? I showed in a previous video how to do this with through-hole components. These worked really well, but they weren't as nice looking as the commercial versions.
In this video, I'll show you how to make the same wireless LEDs but using surface mount components.
You can of course just buy these on Aliexpress - s.click.aliexpress.com/e/_A4gUEH
But if you want to build them yourself check out this video for full instructions: • DIY Wireless LEDs Made...
The inductor I'm using is a 2.2mH 0503 from this series: www.mouser.co.uk/datasheet/2/... these are pretty standard components so shop around.
For the capacitor, you'll need 220pF and I'm using a 1206 size. I'm using the same 1206 size for the LEDs. Any generic LEDs and Capacitors will do.

After viewing your previous videos, i desoldered SMD inductors from many old boards i had around and i built 10 of these receveirs with 0805 components as these were what i had at hand. To simplify the oscillator section i used a ZVS circuit built on Logic MOSFETs. I managed to get idle consumption down to 80mA, and the range is about 15cm, very likely thanks to the matched resonance between the primary transmitter coil and the receveirs ones. Thanks for the inspiration, i really enjoy your content. Keep It up!
That’s amazing! If you have any photos or a video then it would be great to see them in action.
Such patience and dexterity, you are an inspiration! I appreciate your esoteric projects and fresh perspectives. Wishing you the best in the coming year!
Thanks! I’ve got lots of ideas for next year projects - just need to clone myself to get them done… wishing you all the best as well.
That's fantastic! Thanks m8! Didn't expect it to be that small when finished!
Absolute stonks!
I love this version much more than the TH one! Great video, thanks!
Thanks! They are a lot neater.
I have been using this wireless power concept for quite a while using commercial wireless power modules. Now i can build homebuilt.. thanks.
This is awesome. I'll definitely be making some, so thanks for sharing!
No problem.
Been there with launching components..lol. Good job. Happy NewYear.
There was quite a bit of swearing that I edited out...
Just like I made mine😀
I use another soldering technique.
With a small D soldering tip, I tack solder the components 1 by 1, on one side. There is enough tin on the inductor to act as a tack-weld.
Then I solder the other side properly. Then I go back and solder the first side.
I learned this trick when building 600 servo boards I was selling to a customer, all by hand! 603 size resistors made me do it!
Nice - my SMD soldering skills are pretty limited - though I've got a board that needs soldering soon so have to get some practice in. Not sure I could do 600 boards though!
@@atomic14 Don't sell yourself short. You have good soldering skills.
Thanks for sharing this, I watched your few others on this too! I just started using some of the commercial ones (embedding them in resin cast monsters), and looking to make my own UV led ones -
I am a total noob to any of this (trying to learn with specific projects), I was just curious though, what does the capacitor do in this scenario? Would it not work with the LED directly connected to the inductor? Or is it storing some extra power to not overdo the led?
Thanks so much, definitely subscribed
I did actually enquire if jlcpcb could make a batch of these with the smd assembly on one side, the short answer was yes :D
then I realised how much soldering would still be needed for the inductor side and decided against it :D
I’ve been wondering if it’s possible to make PCBs with the receiver coil on it.
@@atomic14 I did look into that, most of the calculators for PCB inductors only seem to cover single layer designs and most of the numbers I got out where a bit large for the task!
I wonder if there's a way to make one where it doesn't _only_ work well pointing straight up. There's big application potential for these in modelmaking, but only if they work in a wider range of orientations. 🤔
`Wonder if the plate gap in a ceramic cap` will tune without a coil?
Sprinkle these around strong EMF sources for instant bling.
How big can you go with this? Just need to make the coil about 5-10 inches and than I was going to buy the bulbs.
hello i need your help in one project let me know the way to connect with you, This is regarding the smd wireless LED lights
Nice sir very small leds👍
Are 6 different color LED's possible?
Super . I try
I was thinking? will this work with a green 2.2mh throughhole inductor? I was already thinking of this with smd. I did bought the commercial version to start with. And explore abit. The ideas I have with this.. Hope to share them in a while.
Would be great to see them.
@@atomic14 I recieved the small 5v and big 24v commercial version. The big coil resonates at 191khz. The smaller I cant measure. Since I only have a multimeter (no scope, I should buy one). I ordered a bunch of parts to start the experimenting. When I got a working led myself I will start to implement the idea's I have.
The resonant frequency of your LC setup is 228KHz.
What's your oscillator running at?
For the DIY version of the driver coil I ran it at the same frequency - 228KHz.
@@atomic14 sweet.
Super sir..
Thanks
I want to see what's the smallest possible size you could make these
Probably the biggest limitation is the inductor size.
Just made a batch myself. I used smaller components. The caps and LEDs I used are 1mm x 0.5mm. The limiter really is the inductor.
@@cacaokingdom3122 Wow! What size inductor did you use?? And where did you buy it?
El video mio esta en el YOU TUBE y se llama - Robotizado con CD 4017 , NE 555 Pilotos

Interesting, but not exactly practical. It would be more interesting if they were RF powered transponders, or even if they could be addressed and controlled by data modulated onto the powering RF field.
Out of interest, what are the commercial units used for?
Nice another person who likes to use blutack... you could have blutacked the LED's and capacitor together to make picking them up easier too!
Now that would have been a good idea. The number of times they pinged off the desk...
Ehh.. 2.2 _micro_ henry, yes?
2.2 millihenry and a 220pF capacitor.
@@atomic14 Sorry, my bad!
