El sábado 3 de diciembre vamos a realizar una sesión para enseñar a los interesados a realizar el montaje de este árbol de Navidad. Si estás interesado en asistir, rellena este formulario.
Compra un Arbolito como este en cualquier proveedor:
Kit Model: CTR-30 (three-color light) / CTR-30C (Colorful light)
Operating voltage: DC4.5-5V
Power supply: 3 AA batteries or USB charger
Dimensions: 60mm * 136mm * 60mm (L*W*H)
CTR-30 flash Christmas tree kit consists of three circuit board, allows 36 LED flash alternately, showing a Christmas tree in the space of three-dimensional profile (the night environment has better viewing).
Step 1: Welding CTR-30A circuit board (referred to as A board)
- Soldering four resistors (R1 R3 R5 R7)
- Welding three resistance (R2 R4 R6)
- Welding three transistors, with horizontal installation (with directions)
- Welding three electrolytic capacitors, use horizontal mounting (with direction)
- Welding red LED (with direction)), the red LED numbered D1 ~ D6.
- After folded pin, inserted into the corresponding holes (note the mounting direction)
- The red LED welding finished (No. D1 ~ D6)
- Welding yellow LED (with direction), No. D7 ~ D12
- Welding green LED (with direction), number D13 ~ D18
Now, A board welding finish.
Next using the same method welding CTR-30B circuit board , referred to as B board.
A board and B board has different mounting positions of the two elements:
1. R2 R4 R6 resistance has different mounting position
2. The red, green and yellow LED has different mounting position
- After A board and B board both are welding finish, you can power test whether two plates normal light flashes. A, B board need to continue normal flashing and continue the following step.
11. Welding CTR-30C circuit board, called C board .Welding a DC socket (with direction)
- Welding a key switch (with direction)
- A board and B board combination (with direction, the two plates are positioned like the arrow below), after two positioning arrows are aligned, use a soldering iron to put the two board together.
- Assembly the battery box and C board
A. welding the wire battery case
B. fixed the battery case with screws and nuts
- Combination of A, B, C board (with direction)
- Welding the top LED (with direction)
Congratulation!! You finish the kit!!
