[0:00] In a previous video, I showed you how to make wireless LEDs using through-hole components.
[0:05] These worked really well, but they weren’t as nice looking as the commercial versions.
[0:09] In this video, I’ll show you how to make the same wireless LEDs but using surface mount components.
[0:14] I’ve selected the same component values as I used before. A 2.2mH inductor and a 220pF capacitor.
[0:22] The inductor package is a 0503 which is a 5.5mm x 5.3mm footprint size. I picked this particular

[0:29] one as from the datasheet it looked like it had good-sized solder pads on both sides.
[0:34] For the LEDs and Capacitors,

[0:36] I chose 1206 sizes as they fit nicely across the inductor pads and are reasonably easy to handle.
[0:43] Soldering up is pretty easy, we just tin one pad of the inductor.
[0:47] I’m using a bit of blue tack to hold it in place which stops it from moving around too much.
[1:07] As in the previous video, I’m using two LEDs and I’ll put

[1:10] these in opposite polarities to take advantage of both sides of the signal.
[1:15] These LEDs are quite handy as they have an arrow on the bottom telling which direction they run in.
[1:26] To fit the two LEDs and the capacitor I’ll be putting the capacitor on its side.
[1:31] This is really fiddly and it required a couple of attempts

[1:34] to arrange the components and lift them all in one go.
[2:00] Once you’ve got them arranged and you’ve picked them up we just need to melt the solder.
[2:23] We can then just solder the other side of the components.
[2:36] I tried several different variations, the capacitor in the middle,

[2:39] one single LED and a capacitor. They all worked pretty well.
[2:42] I’ve put a link to the components I used in the description and you

[2:45] can watch the previous video to see how to do the complete build.
