16 Channel InfraRed remote controller
https://www.electronics-lab.com/16-channel-infrared-remote-controller/
16 Channel Infra-Red remote controller is based on PIC16F73 Microcontroller from Microchip. The receiver part follows RC5 (Philips) Code Format. Tiny receiver provides 16 latch outputs or 8 Latch + 8 Momentary outputs by closing Jumper J1. All outputs are TTL and can drive Relay board or solid state relay. The circuit uses TSOP1738 Infra-Red […]

Consolite – a Tiny Game Console on an FPGA
https://www.electronics-lab.com/49620-2/
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 software toolchain. In […]
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
https://www.electronics-lab.com/learn-play-sound-arduino-building-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 displays or LEDs […]

samDEV_09 – Mini devboard for Atmel’s SAMD09 ARM Cortex M0+ Microcontroller
https://www.electronics-lab.com/samdev_09-mini-devboard-atmels-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 therefore has […]
Simple nanosecond-width pulse generator provides high performance
https://www.electronics-lab.com/simple-nanosecond-width-pulse-generator-provides-high-performance/
by Jim Williams @ edn.com If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The circuit of Figure 1, built around a quad high-speed comparator and a high-speed gate, has settable 0- to 10 ns output […]
