Perfect Gift for a techie Wife! <br>Very good instructable.
Congrats on being a finalist!
nice project, i like that idea of using magnet as contacts and switch ;)
Instead of the white led, get some rgb 2 pin color changing ones. Rest would be same. <br>You can get them cheap on Ebay.
I will test them asap Thanks !!!
Hi Lorenzo. <br>You may may need a current limiting resistor in your circuit depending on the forward voltage of your LED. eg. Some LEDs have a forward voltage of 2v. You LED probabbly needs about 2mA for nice night glow, so you would use (3v-2v)/2mA= 500Ohms (470 Ohms would be close enough). Some blue and white LEDs have a much higher forward voltage and either not work, or not bneed the series current limiting resistor.
this is awesome!
thanks !!
I want to see the schematic diagram of this,please
<br>the shematic diagram of the led earring is the following <br><br>
never seen anyone use 8020 for accessories before!
How i would love to have a 3d printer im full of ideas but low on funding
Clean and elegant. Love it!
At first I thought it said lead earrings, ouch!
I can't stop giggling to myself, I love this so much! Cant wait to to try it, maybe with different color LEDs. I absolutely love the incorporation of the 80-20 aluminum bar slice.
This looks REALLY HARD! Is it?
Very good project!
Oh, those are fun, I'm glad you added in the ribbon, really makes it stand out :D
