Title: Not a new development, just a board (bored) mod
Post by: 32teeth on May 18, 2010, 04:35 pm
Hey all
This isn't anything super duper fantastic.

but last night, i finished soldering up one of my projects and had some 0805 LEDs left over...   ...so i decided to change the lights on my Arduino board

Power = Blue
Pin 13 = Blue
TX = Green
RX = Red

enjoy

Pretty cool.

I have to say that I considered this on a few things, mainly my Rio Carbon MP3 player which I was going to change the LEDs to blue on but I have never had any surface mount LEDs seperate (not in a kit). I have a project on my (very long) list which would involve a load so maybe after that I will replace all these boring ones on devices I have.

for getting the old SMD LEDs off, or any SMD 0805 things like resistors and diodes i would recommend getting a pair of hot tweezers.
they are pretty easy to solder on.

1. clean the pads
2. use flux on both pads
3. put a very small amount of solder on one pad
4. grab the SMD with needle tweezers
5. align it on the pads
6. heat the pad you presoldered in step 3 and slip the SMD in
7. solder the other side
8. enjoy the fruits and colors of your labor

SMD can go on perfboards as well!

and they are dirt cheap if you buy in bulk from ebay
i bought a 100pcs mix pack (white, yellow, purple, cyan, red, green, blue)

Yeah I have been experimenting with taking them off old boards recently: http://duinoaday.wordpress.com/2010/05/12/smd-led-scrounging/

great write up mowcius!
great site as well http://www.duinoaday.co.uk/ <- bookmarked
my apologies for providing a how to smd list. didn't realize you already knew how! ;)
