002 - selfmade magnetic or mechanic switch

[itspennysboat]

haha good idea

[redxz0r]

can u tell me what's that black thing which u melt with fire?

@redxz0r

Hi , that's called "heat shrink tubing" , it's a tubing/sleeve that you can use to insulate or protect soldered joints in electronics projects or for any other application were you can use a tubing that will shrink when heated.

[smellyfry]

won't the 2 blades get magnetised and become attracted to each other causing the circuit not to open ?

[AndreaGanora]

Doesn't happen , to the ones I've made at least.

hi, that great, looking to make a magnet switch for on / off for micro RC sub,

excellent work,

[lennertmets]

ze zwitch XD

[tinkertom2118]

thats ok but use a stiffer non magnetic material lined with a conductor for the bottom of the switch, then the magnet will pull down the thinner upper part to close the circut without any drag. nice work! bye guys

Good suggestion, but could you build one and video it for us to provide proof in production of what you propose? I mean this gentleman has "shown us" and you make a great proposal, but I'd like to see the practical production, e.g. demonstrated inventing vs. arm-chair inventing.

Thank you this helped me soooo much...!

[saden007]

thanks now i have build a pulse motor!!!

[sspoke]

with this switch perpetual motion is possible u could make a pulser like hand movment but a switch! which is awesome!

I just took apart a small window alarm that has a switch inside that works just as you have in this video.. pretty neat! Thanks for the tips.. I was looking for a reed switch and think I might go with the mechanical version you show to make it easy to adjust the timing..

Whatever you do, do NOT use your mothers good sewing scissors to cut the razor blade.

THANKS A MILLION!

[1miltond]

toes anybody knows of a elctronics component suppliers small orders on line please let me know

[boxa888]

wow very nice good job

If you will connect a capacitor of the appropriate value to each side of the reed switch you will eliminate the arcing and that energy will then add to the power of the circuit without being lost in the arc and your reed switches wont burn out so easily.

How do we calculate or guess what size/type of cap to use? Can you provide link for more info? ~~I spent ages designing a circuit using two pairs of reed switches, only to have them burn out within hours!

[ibercaracole]

Excellent tutorial.

[Thomastuantran]

The best I've seen yet on a very inexpensive, very reliable, very simple and very quick to construct. Definitely a Genius playing with very little money out of pocket.

[kubikop]

Good tutorial.

Your rotor looks well built, can you do a video of it working?

[AndreaGanora]

Thanks

I'm working on it i'll be online within some hours ; )

The system is not completed yet but I'll post the work progress anyway
