How to use:

1. Assemble electrode needle. (electrode needle must be assembled before starting)

2. Connect one end of the adapter to the socket and the other end to the DC connector.

3. Connect one end of the audio cable to a smartphone or computer and the other end to a circuit board.

 

Note:

1. While it is working, do not touch the electrode directly with your hands, otherwise it will burn your skin.

2. Do not touch the electrodes, heat sinks, circuit boards and copper parts. Do not use any conductor to touch the secondary coil, as this will damage the Tesla.

3. During the operation of the coil, it will cause serious interference to the surrounding electronic products. This is the characteristic of the Tesla coil itself. Please do not let the mobile phone or other electronic products close to the Tesla coil to avoid damage.

4. If Tesla does not start successfully, please touch the discharge tip with an insulated screwdriver, but do not touch it for a long time, it may burn Tesla.

5. Do not use the coil in a flammable or explosive environment.

Specification:
Name: Low Temperature Hot Air Engine Model 

Size (Dia*H): φ89*135mm

Material: Metal Aluminum

Surface Treatment: Anodic Oxidation

Product Weight: 152g

Features:
1. . This low temperature stirling engine, runs on a hot cup of water (Do not put it above a candle or other fire), could be a great conversation starter at work and unique gift to families or friends or for class demonstrations.

 

2. It is almost ready to run: after the installation, put it on a cup of hot water or Ice water, wait about 20 seconds, gently flip the wheel,then it will run itself.

 

3. Basically you can run this engine up to 20 minutes with a cup of warm water (the engine must be cool). The bigger the temperature difference between the top and bottom plates the higher RPM you will get. This works best with a hot cup of water underneath and an ice cube in a plastic bag on the top (there is plenty of room for one ice cube on top).

 

4. Durable, well made, sytlish, and adjustable.Very fantastic craftsmanship, made with Metal Alloy.

 

5. If there is a little noisy, ONLY use a little graphite dry lube or a pencil quieted it down nicely. Do not use oil to lubricate,which will mix with dust in the air, and become a oil-dirt, finally make the friction to be even bigger.The stirling engine can't run smoothy.

Principle:

This low temperature stirling engine,runs on a hot cup of water (Do not put it above a candle or other fire). The engine's speed depends entirely upon the temperature difference between the hot side and the cold side. In the case of using a cup of hot beverage, not only is the engine transferring the beverage's heat to the surrounding air, there are air currents constantly crossing the top (cold) plate. The differing temperatures will cause the engine to slow or speed according to the net difference between the two plates. For some extra fun, you could obtain a USB-powered cup warmer and place engine on that. After the warmer finally made it to full temperature, the engine will chug along like a champ.

Specification:

Length 250mm Width: 110mm Height: 100mm

Power: 130 motor

Color: red, yellow, blue Random delivery!

Experimental equipment: wheels, switches, wires, DC motors, battery boxes, EPS bodies, diagonal pliers.

Switch: A device that turns the power on and off

EPS body: the overall structure of the wind number

Applicable to: Children over 6 years old (parental guidance)

Students in the third grade or above can try independent production.

 

Features:

1. Assembled models propelled by aerodynamics can help students recognize air propellers.

 2. The wind-powered aerodynamic speedboat is ideal for both surface and land, and its steering is controlled by an adjustable front wheel (rudder).

3. When you test, you only need to adjust the angle of the front wheel (rudder) to change its navigational trajectory in the water and land. The left yaw will adjust the angle of the front wheel (rudder) to the right, and vice versa to the right.

4. When adjusting, the angle must be controlled as small as possible to avoid overshooting. After repeated adjustments, the model can reach the state of straight sailing.

5. Let us act together and accept the double test of “Winning the Wind” to make ourselves a master of amphibious control!

Instructions:

-The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.

-The packing bag of alcohol lamp cotton wear into the metal cap lamp.

-Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.

-Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.

 

Note:

-There will be the operation of steam,when steam too much time, the engine will stop working,

inside and outside the needle often set aside to reduce friction

-Do not rotate the nut too tightly, otherwise the glass is broken, if the piston is cracked,

can be bonded with glue.

-The alcohol lamp wick do not touch the glass, do not get too tight ring

-Pulling the piston connecting rod can not force the front end, because the front

end is easy to break
