- This magnetic pendulum has been running non-stop since 2007. I intend to keep it running forever.
The single electromagnetic coil in this circuit serves a dual purpose. It's used as a timing sensor and to repeal the magnet keeping the pendulum swinging. The circuit runs on 2AA batteries for up to 3 months. This unit has been running for 24/7 since 2007 with no adjustments or maintenance.
The pendulum arm swings on a single skateboard bearing. It's runs completely quiet.
Hi, I have done the same thing, same circuit, I used 36swg wire, it's working very well
If you used magnetic bearings then it would run for a few centuries for sure.
brilliant LOVE IT
That seems to work just like a bedini pulse motor...
I know this is an older post, but exactly what I am looking for. I got a hold of the Nuts&Volts article. What if you use a little lighter wire, as long as you get 9-10 ohms, would that still work, I have some #30 instead of #28, I also read somewhere (I think on your pendulum) something about connect a wire to the outer trace for some reason, is that you. Thanks
@@teslacoil so I sort of got it working, but I need a real big strong magnet for it to run, which is throwing off my adjustable length for timing. I didn't have a 1M variable resistor, so I put in a regular 1M resistor, if I reduced this, what would that do, make the coil stronger? thx
@@teslacoil what do you mean the outer wire stops the circuit going into oscillations? I have tried many two transistor circuits for my pendulum clock. One of them worked correctly but it not stable. It works very well with an aa battery over night and at morning I find it vibrating with no oscillation. I couldn't understand the reason. I have a coil with around 45ohms wound with 0.2mm wire.
@@teslacoil here is the circuit that I have applied: czcams.com/video/CpSxRht3qfU/video.html
Wow, this is fantastic. What is the circuit board that you used?
Hello,
I have yet again another question for you that may be stupid. Do you recommend building the coil first or the circuit? Also, how approximately how much magnetic wire is needed for the coil?
I have started to try and copy this but it's difficult to start..! Many thanks
Are the batteries being changed every 3 months or were only two AA batteries needed to start the pendulum?
I would love to see how you made this. Do you share the schematic?
@metracommm Is something like the RadioShack "Multipurpose PC Board with 417 Holes" okay for this?
I would REALLY like to try making this, it is awesome! But sadly, I'm not too familiar with electronics so I do not know what materials are appropriate or not..! Thank you for responding.
This is wonderfull, how did you build the coil?
WOuld you provide this as a kit or as a list of parts (specs) and connection drawings?
Thanks in advance.
Awesome project! any chance you can share your schematic? i want to build one for my old grandfather clock, the pendulum wont keep swinging. thanks in advance!
I was wondering if you happen to know anything about the equation of motion for this system? If so, anyway you could share it?
Passa esquema pra nós sou doido pra fazer um pêndulo orbital
Would you be able to send me a list of materials and directions to build this? I would be willing to pay for it.
Did you manage to build a replica? I am looking to do the same but have limited background knowledge. Could you send me any details?
Has anyone been able to build a model like this? If so would they be willing to give me the plans/circuitry details for an academic project...
can i get the schematic???? need it soon
Would this be considered a perpetual motion system?
Seriously...?
pl. send me the circuit i want to make one
