<p>Thank q. it helped 4 my science project.</p>
nice one <br>
I have tried,but after it contacted the speaker have no invoice...thanks also..
you are welcome ... but what speaker
I could see a very cool application of this design if there was a way to modify it so that one 'touch' from the magnet turned it on and another turned it off. Then you could stick a neodine (sp?) magnet on the tip of one of the dozzens of magic wand ibles around here and use it to make some real magic happen by wiring this switch into all kinds of stuff around the house and using the wand like a remote. Is there a way to interface this switch with high voltage applications like light switches?
this is a very good idea and i will tr to make it and upload it <br>thanks<br>
Nice! Thanks for sharing your work!
thanks for give me patch
You are welcome! Good man! Have a splendorous day!
hahaha thx<br>
