Instructions phone calls lights: Phone calls phone calls lights kit can be used to sense the GSM signal display, sensing distance up to 1 m, is a very interesting DIY module. Electrical characteristics: Supply voltage: 3 to 12V Sensing distance: about 1 m PCB board size: 2.2cm * 2.8cm Scope: GSM mobile phone signal, for CDMA phones are useless Note: This is a DIY kit, you need to assemble it. The circuit theory: The main circuit is amplified antenna sensor signal circuit and circuit. Sensing signal through the antenna 3 to S8050 transistor amplifier to drive the LED, so that light up. When no signal is detected, no calls or no GSM phones, LED circuit is not only detects the signal to light up LED. Inductance of production: Inductance 0.25 to 0.5MM enameled available in pen core above can be around 5-10 laps. After a good round with a blade to scrape paint inductor 2, so we go soldered to the board. Package includes: 5 x DIY Kit

Description: Input: 100-240V 50-60Hz Output: 12V Output current: 1A Size: 5.6 x 3.5 x 1.9cm Type: original disassemble bare board Package included: 5 x 12V 1A switching power supply bare board

Description: Suitable for 12V 4pin fans. Power supply IDE interface input. Support 10-way 4pin fans start at the same time, solve motherboard interface shortage and deal with the back EVA double-sided adhesive, you can fix the hub on the chassis. Support pwm function, fan automatic speed control. The PWM interface is connected to the motherboard CPU fan interface via the PWM connection cable, the red interface is the CPU fan specific interface, and the black interface is the PWM regular fan interface. EVA double-sided adhesive in the back side, you can fix the hub in the computer case. Size: 74 x 48mm Conditions To Achieve Temperature Control: 1. The fan is a 4-pin PWM fan, which is very important. Some motherboard 4-pin interfaces are not a real PWM fan jack, they are adjusted by the voltage. Such motherboards can not make PWM control fans. 2. Connect the motherboard 4-pin fan interface, BIOS starts the PWM function. Package included: 5 x 12V 10 way 4pin fan hub 5 x PWM connection cable 5 x Manual

Feature: Work: D Class Quiescent current: 20mA Operating voltage: DC7.5 V- 15V Rated output power: 10w + 10w (8Ω) Frequency response: 20Hz to 50KHz Recommended supply voltage: 12V, the center PIN of 12VDC is "+" Package included: 5 x Audio Stereo Amplifier Board
