Toys & Games From DjuiinoStar on Amazon

★A WORKING MODEL WITH EXCELLENT TECHNIQUE: brushed aluminum base with 4 rubber pads ensures its stability while working; sandblasting aluminum stand cut by CNC router works well as a solid bridge between cylinder & flywheel; stainless steel bearing rod cut by laser cutter is of an ultra-high precision size; aluminum alloy flywheel has a brighter & smoother surface after the finish turning process; use customized thickened quartz glass as cylinder, durable and safe enough to use for a long time.

★LIGHT UP MULTICOLOR LED: equip 12.5mm big power cylinder with 15mm stroke power piston, this powerful engine will light up the colorful LED on the generator. Electricity generated can be used to power other devices as well. As we get used to observe the whole working process in a bright place, so you may not see the light clearly. But if trying to get this engine model going in a dark room, you’ll be totally fascinated with the LED shining with a wide range of color in the darkness.

★GREAT GIFT FOR EVERYONE: with visual texture and aesthetic appearance, it’s simply a piece of art. Our customers are satisfied with its strongly stable structure and exquisite body. This engine is mainly constructed by metal, HEAVY enough to rotate quietly and stably at a speed of around 2300 RPM! Frankly speaking, you’ll not feel regretful on purchasing of this one. DjuiinoStar stand behind its products, buy with confidence!

★Wonderful shelf candy: it's a piece of art built by you from scratch. Put it in your office and it'll be a great conversation starter. Unique design and nice workmanship make this model a great decor for your desk or shelf.

★Another kind of Stirling Engine?: No. It's a model of a 4 cylinder, 4 cycle gas car engine that runs via two electric motors powered by a 500mAh rechargeable lithium battery. You can find a YouTube video of one being assembled on the channel "NDA Hack" titled "How to build Car Engine Assembly Kit - Full Metal 4 Cylinder" if you're curious.

★GREAT TIME KILLER: It can magically stand on almost any places: fingertip, tip of a pencil or a thread. Is truly addictive especially for kids (buy one for your kids to buy yourself some quiet time!). Our product is much more robust than any other traditional gyroscopes on the market, will survive when drop from high places to hard ground (which always happens). It's great for adults too: whenever you want to start or end a conversation, this one is a very good choice.

★WHY CHOOSE US?!: This product is a well-designed and crafted mechanical toy, a fantastic gift for people you love. Many people bought our gyroscopes as gift to families, teachers, friends and seldom will it fail to cheer them up! DjuiinoStar has gained very good reputation on Amazon since 2018. We hope you will like it and we do hope you will think it worth the money invested. And we stand behind it to guarantee that.

★Initial speed of the rotor is around 8000 rpm. Personally I like to hold it in hand to feel its power when I was bored. Can't say it's the best gyroscope available, but when take the price into consideration, this is the best one.

★★★★★IMPORTANT NOTE: SLIGHT VIBRATION IS NORMAL ESPECIALLY WHEN IT JUST START BECAUSE THE INITIAL SPEED IS TOO HIGH. PLEASE AWARE OF THIS BEFORE PLACING ORDER.★★★★★

★PRECISION CRAFTSMANSHIP AND FINE MATERIAL: CNC machined from solid metal to ensure perfect balance and robustness; Silicon Nitride Ceramic tip provides exceptional wear resistance for long term use; knurled upper top body for better grip and faster spins; length of the grip is about 0.55" so if you have a big hand it will be easy for you to spin. It's circled by a bronze ring which is also CNC machined. Looks beautifully even if just place at table. Simply a piece of art.

★GREAT TIME KILLER: My former colleague who's in charge of this product line was fired because he spent too much time on spinning and timing. Whenever you feel boring (shopping with your wife or your mother, waiting at airport, running for President of USA, etc.) or when you want to have a break at work, or when you have to test if you are still in your dream, this one is a good choice.

★WONDERFUL GIFT TO THOSE YOU LOVE: this tiny shiny top is easy to play, easy to carry (overall size is around 1"x1"x1"), hard to be broken (CNC machined from solid metal), and most importantly, it can be played almost anytime, anywhere; play it with your families to see who can spin it the longest is a good idea, kids will be excited (one of them will not soon since loser maybe will have to do housework, sad); it can also be used in pursuit of perfect Zen-like state (DON'T DO THIS AT WORK!!!).

★MOST CLASSICAL STIRLING ENGINE: with elegant design and fine workmanship, this is a beautiful piece of art. Many people are satisfied with the fit and finish of our engine.

★SAFE FOR KIDS: Complies with the applicable regulations and standards under CPSIA and any other acts enforced by CPSC; passed Toxic Elements Test/Flammability Test/Physical and Mechanical Test of ASTM-963 Standard Customer Safety Specification For Toy Safety.
