“Warduino is project to replace IQRF modules. It is designed to be compatible with arduino. The base of HW is microcontroller Atmega328 and wireless chip SI4432.”
“Toner transfer method for making PC boards is very practical and economical. The use of heat for the transferring is not. Large boards expand with heat (more than the laser print) and heat is applied to the top of the …
“Another small board, this time for a INA219. The INA219 is a high-side current shunt and power monitor with an I2C interface.”
“Dual Motor L298 H-Bridge Control project can control two DC motors connected to it. The circuit has been designed around popular dual H-Bridge L298 from ST. This circuit has current sense resistors for both H-bridges to provide voltage which enables …
“This project is just a small part of a bigger project I have been working on for the past couple of years (on and off). The background to this project is that a couple years back, I found a modern …
“Today, when building mobile devices one might think about touch displays. I decided to not use them because they do not allow for good, precise single handed operation, and I think that is an important feature for my Little Helper …
“The Tiny Mic Preamplifier based is based on a single transistor amplifier design. It amplifies the output of the electret condenser microphone. Good choice for Karaoke.”
“Light Sensitive Audio Oscillator project is a fun loving project which will create different sound effects depending on the light falling on the sensor”
“A light system, capable of simulating the alternation of night and day, that will make your nativity scene – be it a small or a big one – even more realistic. Our circuit is capable of piloting four light loads, corresponding to …
“1.2V to 35V Adjustable DC-DC Converter project has been design around TI’s LM2576-ADJ IC. Inputs supply 40 VDC. LM2576-ADJ is a monolithic integrated circuit that provides all the active functions for step down switching regulator …
