USB Power supply Active Load Tester or short PAL Tester is unit designed for testing the quality of the power supplies. Idea was to create low-cost, precise device for simultaneous measurement of Voltage and Current drawn from the device under test. This is one of my weekend projects that I have decided to release to […]

Summary The electronics trend in automotive is continuously rising due to the demand in the market. The technological developments are now into embedded system in which the manufacturers are developing products that suits to the needs of the people. In this design, it features a automotive lighting control using an MCU with S12 CPU core,

Searching for a compromise between the quality (materials, design,…) and production costs is a theme at development of every device and naturally – also at development of components. Also from this reason on the market can be found enclosures with a various wall thickness, with various temperature resistance, etc. and so everyone can choose according

Oscilloscopes and Signal Generators are two essential electronics devices to create and test electronic circuits. Unfortunately, these devices are very expensives for students starting electronics, or makers who want use electronic circuits in their creations just once… The idea of my project is to rethink your smartphone as a portable, powerful and secured platform, able

Writing Your Server Script Don’t forget that first you need to flash both your ESPs with NodeMCU firmare. Copy and paste the code below into ESPlorer. Summary: The ESP Server acts as an Access Point and it has its own SSID=test and Password=12345678. The server is continuously listening for a connection, when it successfully establishes a connection

The ATtiny24, 44, 84 series only has 1 external interrupt (INT0) [Page 48 of the datasheet]. This is the interrupt that we are most familiar with using on the Arduino. You can simply use this interrupt by saying “attachInterrupt()” While it only had 1 interrupt, I wanted to have two buttons on my clock: one
AMQUMO logs 4 environmental parameters: Humidity Temperature Ambient Noise Brightness The data it is logged to the xively.com platform, and displayed to the user through 4 bi-color leds. It can be used to monitor you Office Ambient Quality over the parameters logged. This project it is built upon the xively logger ATmega328 library: http://davidegironi.blogspot.it/2014/12/a-web-configurable-xively-logger-build.html So, a

This is a multi-chapter instructable. I will be describing the making of a short/medium range RF remote-control using the UHF 433Mhz frequency. It´s impossible to setup & adjust a RF transmit-receive link if you are not sure the transmitter is working properly.At 433MHz, your multimeter or even a regular oscilloscope are totally useless. In this

PORTLAND, Ore.—Today Yole Development predicted that power transistors would radically shift from silicon wafers to silicon carbide (SiC) and gallium nitride (GaN) substrates—to achieve higher power in smaller spaces, according to its GaN and SiC Devices for Power Electronics Applications report. One of the big drivers behind the shift is the electric vehicle (EV) and

I think that one day, all food cupboards & fridges/freezers will be smart. All products will have an RFID or video recognisable label which will update a list of product usage. Your local supermarket will gather this information & replenish your products as required – who knows ?? So, I came up with the idea
