LoRa is a useful technology if you need to send data a long way at low power levels. Leveraging this, [5Volt-Junkie] decided to build a small pager named the LoRaNicator. Those who love a detailed build log will enjoy this. The pager features everything up to and including the kitchen sink. A Cortex M0+ runs the […]
While robotic arms can handle a wide variety of tasks, the specific job at hand will have a major influence on the type of end effector used. For sorting ferromagnetic parts an electromagnet might be enough, while for more accurate location a mechanical gripper could be employed. If you’re working with particularly delicate objects or

Adding wireless charging to furniture and other consumer goods is a nice way to add some oomph to an otherwise boring product. NXP’s NXQ1TXH5 provides an interesting, albeit difficult-to-prototype way around the problem. Creating a Qi-compatible is as easy as assembling the example circuit shown in figure one. From a technical point of view, the
Part of the problem I’ve been seeing with inexpensive IoT dev boards, is that the design around the power system hasn’t been very good. Here’s my attempt to fix that. This is a battery-ready module with a proper lithium battery charge circuit, lithium battery protection circuit, power supply, and antenna, all in a 1 inch

Dejan Nedelkovski had built an Arduino security and alarm system project that uses an ultrasonic sensor for detecting objects and a buzzer for notification. Components needed to build this simple system are: Arduino board, LCD display, 4×4 keypad, ultrasonic sensor and buzzer. The circuit can be connected as shown in the schematics below. In order
Extending battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs, Microchip has announced a linear Low Dropout (LDO) regulator. With an ultra-low Iq of 250nA versus the approximate 1uA operation of traditional devices, the MCP1811LDO reduces quiescent current to save battery life, enabling end-users to recharge or replace batteries less often. The

Potentially, one of the great things about having a device connected to the network is that you can update it remotely. However, how do you make that happen? If you use the Arduino setup for the ESP8266 or ESP32, you might try [scottchiefbaker’s] library which promises to make the process easy. Adding it looks to be simple.

The release of the LBAA0ZZ1QM (US) & LBAA0ZZ1TY (EU) LoRa Pico Gateway 14-pin metal-shielded module has been announced by Murata. Supporting eight channels and available in two variants for use in either EU or US ISM bands, this ultra compact module measures just 55.0×21.0×3.4mm. Designed as a single substrate low cost module that can enable

In this instructable I am going to show you how to build a weather station that logs the information that it collects on a sd card. Step 1: If You Prefer a Video Here It Is Step 2: Get All the Parts You need, 1 Arduino board, I used the pro mini 1 dht sensor
Smart electronics help us save time at home especially when one cannot wait to get the party started. To provide a solution to this situation, Amazon created speakers and stereo systems, which are equipped with the Alexa Voice Service. Alexa Voice service gives a new voice experience to electronics devices and adds a more personal user
