I found the best way to work with SMD LEDs, was to 3D print a mould / holder, to keep the SMDs in position, I then hand soldered them with a very fine tip, wasn't too hard at all.

@Dave Lordy Can we see a picture or stl of the mould?

It's easier to put some solder on the pad and then hand solder them. No need for any mold.

@@John-ed2wj I was trying to do a perfect circle of very small SMD LEDs (4x2mm if I remember correctly), it only takes one or two to be half a millimetre out and it ends up looking messy, eventually (after various other failed ideas) I ended up printing little 3D guides that I could drop the LEDs into, with space to allow me to solder.

What does it mean if an LED datasheet has forward voltage specified as a range from min to max (no average or typical). What should I use to calculate the resistor in this case? They do say what the forward current is.

@Kevinhobbytime 9 ай бұрын

I so much want to make a POV clock with smd parts. It would be lighter and less clunky looking when not spinning. I also want to incorporate a qi charging coil to the propeller so the arduino and motor does not have to be on the board with a battery, reducing spinning weight and also making it neater in appearance. Now if i could only figure out how a smd hall sensor would mount to trigger a magnet and set the timing….

The polarity markings made me think I was going nuts when I first used SMD LEDs for modding tail-cap switches on torches! _Mmmm, illuminated tail-caps._ I had a MM, but it didn't have a diode check option, so my method was 2 wires off an 18650 direct to the LED, with a 50-50 chance of blowing or lighting. I'd make sure I had the markings & polarities memorised, then to another colour LED, then another, only to find the last ones wouldn't illuminate. 🤔 I double and triple-checked my soldering, the SMD resistor values, wiring, et cetera before finally realising that LED manufacturers are malicious idiots and that I was indeed still sane, _just,_ lol. 🤦 I now have a much more capable MM. It would have been handy if I'd seen this video a while ago, though, possibly, I'd have fewer grey hairs. 😆👍

I need your help. I'm a totally newbie in electronic and I bought some little project to build some blinking LEDs on a star shaped PCB. I've broke one led and took one from another previous kit that I had a spare. Only the replacement LEDs light and the other LED are not doing anything. Ive test those with my multimeter and every LED that I test with the diode mode light the replacement. The project use 5-6V and I use a 5v cell phone charger on a little usb pcb board that I had in my hands. The voltage of the board gave me 4,62V I don't know if there's a malfunction in the chip that makes the light blink or if the replacement LEDs need less power and for a reason that I don't know, take all the energy. Thanks for your help

How to avoid wasting power in the resistor?

@TheMilanMovies Жыл бұрын

My guess would be to use a power source with a lower voltage, this way you don’t have to lower the voltage (as much) to power the led. Get as close to the forward voltage as possible, but remember that the voltage can drop when using more components or when batteries go down on power (if batteries are used).
