High Current Discrete Half-Bridge Based on IR2104 or IR2101
This is a discrete Half-bridge driver based on IR2104 gate driver IC and low impedance high current N channel IRFP4368 MOSFETS. The IR2104 is a high voltage, high speed power MOSFET driver with independent high and low side referenced output channels. HVIC and latch immune CMOS...

Dynamic-load circuit determines a battery’s internal resistance
by Jim Williams @ end.com The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery's electrochemical condition and construction. If you attempt to use an ordinary ac...

Consolite – a Tiny Game Console on an FPGA
Robert Fotino has design a video game system on a FPGA. He writes: For my latest project, I am diving back into Verilog to create the hardware side of Consolite. For those who don't know, Consolite is the name I've given to my design of a tiny hobbyist game console and associated...

Butchered USB TTL Serial Adaptor
Aaron Brady writes: We popped open the case, and there were two main ICs, a Prolific 2303 (the USB to Serial IC) and a ADM3251E (the RS232 line level convertor). I tried to desolder this with no success, but Bas stepped in, cut the leads with a craft knife and ran the iron over the...

Learn how to play sound with Arduino by building a DIY Micro Piano
In this video we are going to learn how to make sound with Arduino. We are going to build a simple Micro Piano in order to demonstrate the capabilities of the tone function. Let's start! Playing back sound is great for adding audio feedback to our projects. So far we were using...

samDEV_09 – Mini devboard for Atmel’s SAMD09 ARM Cortex M0+ Microcontroller
A Basic board to test the Atmel SAMD09. On board there is also a CH340 uart to usb bridge Build this board to getting started with the SAMD microcontroller family after I made the mistake to try the much bigger SAMD21 first. The SAMD09 used here is he smallest from this family and...
