MiOYOOW Sound-Activated LED Light Up Glasses Soldering Practice Kit

The practical soldering kit are used to installed to a LED glasses. Control LED flashing through speech or music, the louder the sound, the more obvious the LED flashing effect. You Will Be the Center of the Party Who Gets a Lot of Compliments When Wearing the Cool Light Up Glasses Made by Yourself.

Not only to improve your soldering skills, you will also will be more familiar with electronic components and learn more interesting electronics things. 

Installation Tips:

1>. User needs to prepare the welding tool at first.

2>. The soldering iron can't touch the components for a long time(3s), otherwise damage components.

3>. Pay attention to the positive and negative of the components.

4>. Strictly prohibit short circuit.

5>. Make sure all components are in right direction and right place.

This Instructable shows how to build a LED light up glasses step by step. Let's Do It!

1> Install 1pcs 2Mohm Metal Film Resistor at R8.

2> Install 3pcs 10Kohm Metal Film Resistor at R6,R7,R9.

3> Install 5pcs 1Kohm Metal Film Resistor at R1-R5.

4> Install 1pcs MIC-6022 Microphone at MK1. Pay attention to distinguish between positive and negative pole.

5> Identify the positive(anode) and negative(cathode) lead of LED.The leads of the LED must be installed correctly, otherwise the LED cannot be turned on.Here are four methods as following:

5.1> According to the length of the LED lead to distinguish. The longer pin is positive(anode) lead. The shorter pin is negative(cathode) lead.

5.2> Identify the negative(cathode) of the LED is to look into the plastic case where one can see that the negative(cathode) is much thicker/bigger inside the plastic case than the anode lead.

5.3> Identify by edge of plastic case.The negative(cathode) lead of the LED should be the pin nearest the flat on the plastic case.

5.4> Test by 3V battery or multimeter.The pin is positive(anode) lead which has connect to the positive of 3V if LED can light up after connect 3V power supply.(LED should not be powered directly from the 3V for a short time:less then 0.5second)

  5.5> It is positive(anode) where the white mark “ + ” pointing to on PCB.

6> Install 50pcs 3mm LED at D1-D50. Pay attention to distinguish between positive and negative pole.

7> Install 1pcs 0.1uF 104 Ceramic Capacitor at C3.

8> Install 1pcs ZIP-9 KA2284 LED Driver at U1. Pay attention to the mounting direction as showing.

9> Install 1pcs TO-92 S9014 Transistor at Q1. Pay attention to the mounting direction as showing.

10> Install 2pcs 10uF Electrolytic Capacitor at C1,C2. Pay attention to distinguish between positive and negative. The Longer pin is positive pole.

11> Install 1pcs 10Kohm 103 Potentiometer at RP1.

12> Install 1pcs 5Pin SK12D07 Toggle Switch at S1 on PCB another side.

13> Install 2pcs battery holder positive metal sheet. Pay attention to the placement.

14> Install 2pcs battery holder negative metal sheet. Pay attention to the placement.

15> Put the PCB into the silver mirror frame and pay attention to the toggle switch.

16> Fixed PCB by 8pcs Black PA1.5*5 Screw.

17> Install 2pcs 23A 12V Battery. Pay attention to distinguish between positive and negative pole. Negative pole connect to spring metal sheet.

18> Turn ON work power and adjust sound sensing sensitivity to enjoy this LED Flashing Glasses.
