This small board is based on the CS5171 boost converter from ON Semiconductor. The board is configured to be used with a single 18650 LiPo battery. The circuit converts single-cell 3.7V LiPo battery voltage to 5V with a load current up to 400mA. Board has been designed to fit on the backside of a single-cell battery holder…
This project is an automatic PIR sensor. DESCRIPTION Project is based on HoltekÂ’s IC HT7610A, which is a CMOS LSI chip designed for use in automatic PIR lamp, flash or buzzer control. It can operate in 3-wire configuration for relay applications. Â In our project we have used relay instead of Traic to connect any kind…
TSA6175 is a Bluetooth 5 multipoint audio receiver. You can have many TSA6175s paired and work together. You can also let it work like a normal Bluetooth audio receiver. This Bluetooth music receiver connects to the line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell…
 This USB/Wireless relay module allows computer to control switching of external devices by using the USB port of your computer. It has a wireless extension port, that can work with XBEE or Bluetooth Bee or Wifly modules, which means now you can control your device by Zigbee or Bluetooth or Wi-Fi. The TOSR0x module can be powered by USB…
This is a 4x100W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It has integrated 2xST high performance TDA7498 which supports dual channel audio amplification. Each channel is capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC 14V-39V* power supply. Power input port can be power…
This is yet another digital clock DIY kit for electronics beginners. I have previously published several posts related to the digital clock. This kit is no different from those kits, it also displays time and the additional functions and temperature display and alarm. It also has a photoresistor which makes it sensitive to ambient light,…
This project is the ideal solution for high output, high performance high fidelity stereo head phone amplifier. The project consists of Op-Amp LME49720 and LME49600 as output driver. The LME49600 is able to drive 32Ω headphones to a dissipation of greater than 500mW at 0.00003% THD+N while operating on ±12V power supply voltages. The LME49600…
This is a basic electronics learning kit based on NE555 and uA741. Check out the following images for assembly. You can see all the images on Flickr also. Other images of the kit:
Description: The LM386 is an audio amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200.
SEE ALL THE PHOTOS ON FLICKR This post shows you how to build the Amarino evaluation shield. When you buy the shield package, you will get the following components. Fully assembled kit is now available on buildcircuit.net. The PCB: PCB clearly shows the pin and component names, so, it should help you to get idea of…
The project shown here is a microphone preamplifier that provides high quality amplification, optimized for use in computers, media and mobile applications. The pre-amplifier provides a differential input stage, making the device particularly effective when layout constraints force the microphone amplifier to be physically remote from the ECM microphone. This project features adjustable gain using…
TSA6014 is a compact size and powerful Bluetooth audio receiver. This Bluetooth music receiver connects to the Line-In or Aux input on your home audio system. You can then stream audio from your Bluetooth enabled cell phone or mp3 player to your home audio system.
Isolated high power Mosfet DC solid state relay shield allows you to control high current DC load in switching or PWM control mode. The project can be used in wide verity of applications like DC DC Converters, inverters, DC motor control, solenoid, LED Dimmer, battery chargers and it can control inductive and resistive loads. On board high…
TSIR04B is similar to TSIR04. We have removed the OLED display and put the relay board in a plastic enclosure. This is a TSIR04B Wi-Fi version relay board with optically isolated inputs and temperature sensor port. You can easily control this relay board by your computer or smartphone using Wi-Fi. The communication method also can be changed easily. Replace…
The USBASP programmer is an important tool/accessory for embedded systems engineers/ firmware developers. It is a USB ICSP (In-Circuit Serial Programmer) that allows developers to easily upload firmware/bootloaders on AVR microcontrollers. Unlike what you find to serial programmers like the USB-TTL converters, it does not use a dedicated chip as it runs on an atmega88 (or atmega8), and uses…
