1. Introduction:

• It is an easy to make four-layer round led dimensional cylinder kit. All are DIP components.
• It has more than 23 kinds of special led gradient effects. Some of the effects are star-flashing and lightning effects.
• It also has many spin move effects and led breathing effects.
• All of the light effects change gradually instead of directly which makes the led animation looks more gentle.
• User can hang it up on the Christmas tree to simulate the star flashing effect.
• Soldering grids of each led layer by hand would look terrible, so it has a dual application round acrylic that can act as a template to hold the led in place. This can help you to solder each layer of the led grids more accurately and on the same level.
• It also is used as a case to reinforce the bottom. This acrylic template is important for quality soldering and it makes the led cylinder easier and more precise.

6. Installation Tips:

• User needs to prepare the welding tool at first.
• Please be patient until the installation is complete.
• The package is DIY kit. It needs to finish install by user.
• The soldering iron can't touch the components for a long time (1.0 second), otherwise it will damage the components.
• Pay attention to the positive and negative of the components.
• Strictly prohibit short circuit.
• This DIY installation is more difficult to be installed, please be patient until the installation is complete!!!
• User must install the LED according to the specified rules. Otherwise some LED will not light.
• Install complex components preferentially.
• Make sure all components are in right direction and right place.
• Check that all of the LED can be illuminated.
• It is strongly recommended to read the installation manual before starting installation!!!
• The default code is inside the chip, the function is more abundant, so please do not update the code inside arbitrarily!

7. Installation Steps (Please be patient):

• Step 1: Install 3pcs Copper pillars and M3 Screw on Acrylic Welding Template.
• Step 2: Process 24pcs LED (Not all LED!!!). Curved LED’s shorter pin (negative pole) and form a right angle. Please be careful not to damage the LED.
• Step 3: Install the LED ring. Put the already processed LED on acrylic template. Longer pin (Positive pole) outward. Shorter pin (Negative pole) interconnection.
• Step 4: Use a soldering iron to fix LED negative pole (Shorter pin). The soldering iron cannot touch the LED pins for a long time, otherwise it will damage the LED.
• Step 5: Cut off excess pins. Just cut shorter pin!!!
• Step 6: Install others 2pcs LED rings as the same method.
• Step 7: Install 1pcs MINI USB Female Socket at J1.
• Step 8: Install 1pcs Toggle Switch at S1.
• Step 9: Install 1pcs DIP-8 STC15F104W at U1.There is a dot on one corner of the IC and there is a mark on PCB where the IC can place on.These two marks are corresponding to each other and are used to specify the installation direction of the IC.
• Step 10: Install and fix the first layer LED ring. Note that the pins of these LED are not bent.
• Step 11: Put some tin on the root of positive pole in order to fix next layer LED.
• Step 12: Bend the next layer LED pins slightly in order to connect the 1st layer.
• Step 13: Connect LED layer. Please be patient when connecting each layer.
• Step 14:Connect the negative pole of the 2nd layer to COM2 by white wire. This layer of LED will flash normally if the power is turned on.
• Step 15: Install the 3rd layer of LED on the PCB and this layer connect to COM3 by white wire.
• Step 16: Install the 4th layer of LED on the PCB and this layer connect to COM4 by white wire.
• Step 17: Connect to power supply and enjoy the effect.
