This guy REALLY LOVES his cat. Mad props.

If you used magnetic bearings then it would run for a few centuries for sure.

Hey I’m very familiar with rasp pi, electronics, sensors etc. I’m going to go ahead and do this. Where did you buy the computer case for you pi?

Please start the dryer drying again when you come in againwill you

What makes and models is the compatible with? Or is this limited to LRS devices? Thank you!

I just have to work how to turn this into free burgers...

Passa esquema pra nós sou doido pra fazer um pêndulo orbital

Hey Tony. I'm an engineer also. How can I contact you? Couldn't find any contact on CZcams or twitter. Thanks in advance

I have a HackRF with a Portapack H2 and Mayhem. Is there any way I can do it with this?

Whats the native range for something like this?

hey im trying to do a similar project as my litter robot dfi sensor is causing issues. how do you control the motor? what driver did you use?

Alright. It finally crossed over. So that is what happens if you keep pushing someone on a swing set.... I like it.

Omg this is giving me horrible ideas..😈

Hi there! Do you know how large this can be scaled? 5 ft? 6 ft? If so, can you advise what I would need? Thanks!

Can you share the connection diagram

pretty cool

Hi, Tony, great video! I have a question about this: how do you program on GNU Radio the duration of each bit to be transmited, and also, how you set f1 and f2 for FSK? I didn't see that on the video. Thanks.

I can already see everyone jumping up at the same time in the restaurant. :)) I think these things are a bad habit anyway. You can't tip for self-service.

Nice TC. I have been working on my (multi-static) SGTC for the last ~2+ months (nearly 3months now, actually). I have had it producing streamers that would occasionally hit the ground (toroid center height of ~36"{+ or - a few inches} above the ground). However, running it without any current limiting isn't desirable for several reasons that I won't get into ATM. I have been trying different things for current limiting (such as the primary coil(s) from junk MOT's I have lying around), but I just can't seem to get it working well enough to fulfill my needs or achievement goals I wish to accomplish! My current setup is undergoing a major design change to the MMC Bank, Primary Coil, MSSG, etc. and I've been trying to figure something out to get the best *gain/sacrifice* ratio (an unfortunate consequence of current limiting my Dual "MOT" power supply😐) so I can get the power output that is/should be- acceptable for the PS setup. I was mainly curious about how you might go about trying to best address the issue?! If you would be so kind to offer me some helpful suggestions for designing an RLC circuit, or perhaps, maybe only using a specific design and arrangement of calculated hand wound Inductors?! Or, perhaps, just Some other ideas you have tried/would try?! Any advice on how to best achieve this "ideal"- reliable, consistent performance with a "Current limited-Dual MOT" SGTC design, you would most certainly be greatly appreciated!👍😉

Hi Tony. Thus is great! We own litter robots and are very frustrated with their flakyness and have been thinking about doing something similar. When I stumbled across your video and realized that we may not have to reinvent the wheel, if, of coarse you are willing to share. I can code and my hubs can do circuit boards and other hardware things. Are you willing to post details of how you put this all together? Your help is appreciated. Thank you!

How are you powering the pagers? Are you connecting to the charging pins or internally? Voltage? Thx.

Imagine the chaos....

How would you calculate the parts of this setup when the weight of the pendulum is about 170 lbs?

Hi- Nice project. I have often thought of doing something similar, although chiefly because I have over the years found the circuit boards on my LRs to die or become wonky and it just drives me nuts to have to replace them. I am extremely familiar with programming for the Pi and am fine on the hardware side needed. However, I was hoping to avoid monkeying around with my multimeter to read the signals or loads on the various pins for state changes and driving the motor. Would be great if you could post your project on Github or similar. Thanks.

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

can this be used with hackrf_ook? Works ok on a pi4. Has some issue but thats to be expected on a rpi running GNU-Radio

I have done the same thing, using the same circuit as described in Nuts and Volts September 2009 magazine, it's working well, I used 36 swg wire, if anybody want the full details, plz email me on gsuresh2u@gmail.com

Hi, I have done the same thing, same circuit, I used 36swg wire, it's working very well

Chaos at Applebee's!

Use hack is it for radio attack

Hi, what type of coil are you using and how many volts / amps do you use? cheers.

If that ain't worth a sub I don't know what is! Awesome knowledge drop, looking forward to watching your other videos

Hi, just to say thank you for this wonderful circuit that gave me the opportunity to build the swinging sticks seen in iron man.... so thank you ^_^ !

I've always wondered about this!!! The range from the HackRF isn't great, right? A couple feet at the most?

Do you mind sharing your GRC file?

Is there a way to work out what restaurant number the pager is set to?

Here is a project using an ESP32 with SX1278 to transmit LRS telegrams: github.com/baycom/rps and czcams.com/video/AoRPzNYkjQ0/video.html

Very cool, thanks for sharing your hard work, much appreciated.

Hi great vid nicely done ✅ I have a question for you if that’s ok I’ve been having issues with my hackrf just wont tx no red led or anything I went into hackrf_transfer and it says tx is set to default (off) is there a way my hackrf could be internally switched of sir ?

cool my experiments with sdr radio: czcams.com/video/QaOUqX4GzXA/video.html

Awesome!! Is it possible to share your source code?

Thank you for sharing. What a awesome reverse engineering. :)

That's awesome!

oh this is just wonderful ! Thank you for sharing :-)

Great hack, thanks.

Brilliant, can you share the grc file and the python script ? thank you

Nice!

Can u share schmatic diagram....

please take a look to this question electronics.stackexchange.com/questions/376331/electromagnetic-pendulum-pulse-movement and help me to make a swinging pendulum
