Tesla coils are cool, who cannot resist playing with mini lightning ⚡ This Mini Tesla Coil Kit is a great educational toy, these packs of 3 are great for use in group projects. They work much as you would expect, producing mini sparks of energy you can interact with, it also has an audio input allowing you to produce sound based on the audio input. The kit is unassembled and you'll need to provide a power supply to drive it, most laptop power supplies with a barrel jack will be fine for this. You'll need basic soldering skills to assemble the kit.
A Tesla coil is a transformer that operates on the resonance principle. It was invented by Nicola Tesla, a Serbian-American scientist in 1891. It is mainly used to produce ultra high voltage, but low current, high-frequency AC power. The Tesla coil is composed of two groups of resonant circuits (sometimes three groups) coupled. Nicola Tesla tried a large number of configurations of various coils for his experiments over the years, such as electrical lighting, fluorescence spectrum, X ray, high frequency alternating current phenomenon, electrotherapy, and radio energy transmission (such as Wardenclyffe Tower), among others.
Features:
- Great educational product
- Unassembled kit, requires basic soldering skills to assemble
- Requires DC power supply, a spare laptop supply with a barrel jack will do the trick
- Tesla coil functions:
- Electric arc function: the traverse of the rear end will produce an arc. The arc can also ignite
- Power transmission function: after the Tesla coil is charged, small LED's and bulbs can be wirelessly powered
- Music playback function: a new concept loudspeaker for an electric arc to stimulate air to make air vibration produced by plasma. You can play mobile/computer music, but the sound is small.
- Assembly tips:
- 1. Install small components at first;
- 2. Install complex components preferentially;
- 3. Pay attention to the installation direction of components.
- 4. Make sure the soldering iron does not touch the components for a long time. Otherwise it is easy to damage the components.
- Safety notes:
- 1. This product is safe, power is not high, will not be injured by electric shock, but it is not recommended to touch the top of the coil arc, there will be a sense of burning.
- 2. Do not touch the heat sink after a long time power supply, the temperature is very high, especially the use of 24v high voltage heat huge, if necessary, add their own cooling fan cooling, or working hours lead to too hot, please turn off for a period of time Electric use.
- 3. Tesla coil is recommended to work when the body or other objects close to the coil, the coil next to half a meter blank can not be other objects, as other objects as a good conductor will make the coil form a good loop, absorbing the coil energy, making Testers Pull the coil at this time the effect of demonstration or deterioration can not be demonstrated!
- 4. Do not put cell phones, mp3 and other electronic equipment close to the coil, or the coil will produce high-frequency magnetic field interference, making mobile phones, mp3, and other equipment failure or damage!

My Unstoppable Journey: How 'Can't Hurt Me - Clean Edition' Changed My Life Forever!
Format: Hardcover
As an avid reader and self-improvement enthusiast, "Can't Hurt Me: Master Your Mind and Defy the Odds - Clean Edition" by David Goggins has undoubtedly been the most transformative book I've ever encountered. From the very first page, Goggins' unfiltered honesty and relentless pursuit of greatness struck a chord deep within me. His journey from a troubled past to becoming a Navy SEAL and an ultra-endurance athlete is nothing short of awe-inspiring, and it motivated me to confront my own limitations and push past my comfort zones.
What truly sets the clean edition apart is its accessibility to a wider audience, without compromising the book's raw power. Goggins' story of overcoming immense adversity and mental hurdles resonates deeply, and the absence of explicit language only strengthens the impact of his words. Reading his struggles, failures, and ultimate triumphs, I found myself on an emotional rollercoaster, laughing, crying, and cheering him on with each turn of the page. But more importantly, the book empowered me to embrace discomfort, tackle my fears, and cultivate an unbreakable mindset. Thanks to Goggins' candid narrative and practical tools, I now approach challenges with newfound tenacity, and I'm well on my way to achieving goals I once considered impossible. "Can't Hurt Me - Clean Edition" is a true masterpiece that has forever changed my perspective on what's achievable when we harness the power of our minds.

Buena calidad
Format: Hardcover, Format: Hardcover
Es de pasta dura. El material de las hojas se siente de buena calidad. El tamaño de las letras es adecuado. Mi perro lo mordió un poco por eso en la foto sale así. En cuanto al libro, es bastante biográfico, y deja las enseñanzas del autor.

Can't hurt him
Format: Paperback
I've had many conversations with different people about Goggins, and I would have to say it's been a near 50|50 split of people supporting him and people having issues with him.
Here I will address the motivational aspect of the book:
The transformation Goggins went through from his lowest of low points to his highs are extremely admirable. He had a rough start and numerous setbacks that would've been a decent reason to keep his way of life as it was, but he felt stagnant. So he decided to change it but going after one of the hardest things you can do- prepping for Seal training.
Here I will address the methodology of his motivation:
In short, to become a Seal isn't a mere accident. It is 100% intentful. 100% a team required feat and effort. In some instances of the book, Goggins mentions he struggled with some of his peers, maybe even head-butting ideology where he may have gone solo on some things or didn't quite agree with how a team was being run. He has his own self reflections on this various incidents. However, what I would like to note is that the self-reflection exists (*I listened to the audiobook as well which offered other insight not part of the book).
I believe if you take what is necessary from the book: the motivation, the coaching, the curiosity or whatever you can get get out of the book that is a positive influence then that's great! There are plenty of people who do not like Goggins and because of that bias, they don't give credit to the content of his book. I would say, be an educated reader/consumer. There is always something to be learned/gained from other people's lives and experiences.

Thirty years on this earth… and this is the first book I’ve truly read from start to finish.
Format: Hardcover
Reading Can’t Hurt Me by David Goggins didn’t just motivate me it shifted something inside me. It reminded me that struggle is universal, but mindset is the difference. He doesn’t stop when things get hard; he stops only when the mission is complete and then he looks for the next challenge. This book teaches you that obstacles aren’t there to break you, they’re there to build you. If you feel overwhelmed or stuck, this is the kind of book that wakes something up inside you.
Stay hard. 💪🏾
