Introduction In an era characterized by rapid technological advancements and a growing emphasis on collaboration, open source principles have transcended the realm of software and made an indelible mark on hardware development. Open source hardware (OSH) represents a paradigm shift in innovation, fostering a community-driven approach that democratizes access to technology and enables a more…
Here’s one of the easiest, simplest and the most popular FM transmitter for amateurs and electronics beginners. With this DIY kit, you can transmit your voice or audio over an ordinary FM radio within the FM broadcast band. It is a DIY kit designed by Sagar Sapkota. You can buy this kit at BuildCircuit Store….
The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators.
This is a 2x8W audio amplifier board with AudioB plus Bluetooth module. It has perfect class-D architecture (based on TPA3110D2) and every channel has 8W power output. This board can be powered by any DC 8V-16V power supply, it can be used to drive any 4Ω or 8Ω passive speakers.
About Amarino Shield Amarino shield can be used for doing several experiments with Amarino and Android serial emulators. For example, you can operate a multicolor lamp, sensor graph, light sensor, etc. The shield is just a modification of previous shield designed and published by Sagar Sapkota (Buildcircuit.com). Amarino shield 3.0 has added one more header space…
TSA1110 is a smartphone Bluetooth audio volume controller. It has integrated a digital potentiometer and a powerful Bluetooth and its control distance is up to 30m (outdoor). After it gets connected to your audio amplifier, you can use an Android or iPhone App to control the audio volume from the smartphone. There are 3 ports for…
This is a 2x50W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It has perfect class-D architecture (based on TPA3116D2) and every channel has 50W power output. Both channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC 10V-24V power supply, it can be used to…
TSIR04B is similar to TSIR04. In this device, we have removed the OLED display and put the relay board in a plastic enclosure. This is a TSIR04B Bluetooth version relay board with optically isolated inputs and temperature sensor port. You can easily control this relay board by your computer or smartphone using Bluetooth. The communication way…
In this project, you can control an LED and see sensor graph simultaneously. For your convenience, I have used a simple light sensor circuit. The resistance of the photo resistor varies with the amount of light falling on it. The amount of light is varied with LED controller and the sensor data variation can be seen on the Sensor Graph.
