“With LED technology and DIY Electronics being more available to everyone with each passing year, the demand for maker-friendly LED controllers has been on the rise. Currently, low-cost RGB strip drivers are available but offer no flexibility or external I …
“Hi all, in this instructable you will see how a smartwatch can be made using an Arduino board and a few other components. We are going to design and get a custom PCB fabricated which will be the motherboard of …
“When teaching a Math Circle, I was discussing with the students various logic operations and logic gates. We went from basic AND and OR gates to constructing flip-flop circuit and full adder - using software simulation. I wanted to show them …
“Though I don’t do many PCBs, I guess every hacker must have a reflow oven. So this is a project I’ve been pursuing on and off for nearly 4 years: A small, portable, and dirt cheap (less than …
“These past few months I spent mostly at home, as everyone else, and decided to take on a project to improve my time there. I was spending a lot of time in our balcony and got really annoyed by lowering …
“ATtiny13A receives IR signal via TSOP4838, decodes the signal (NEC protocol) and displays address and command (hex values) on an SSD1306 128x32 OLED display. The device is powered by a 1220 coin cell battery. Please remember that only the rechargeable …
“TinyPocketRadio is a simple FM stereo radio based on ATtiny13A and RDA5807MP. It’s powered by a CR2032 coin cell battery and can drive 32 Ohm headphones via the 3.5 mm audio plug. The board size is 38 x …
“Hi there, today we will be learning how to make an audio amplifier using SMD version of LM386. We will look at the datasheet info, the circuit diagram in EagleEDA, then the PCB in Eagle EDA and finally the actual …
“This Instructable describes my process of building a small handheld computer running BASIC. The computer is built around the ATmega 1284P AVR chip, which also inspired the silly name for the computer (HAL 1284). This build is HEAVILY inspired by …
“This is a headphone amplifier project for audio digital-to-analog converters (DACs) with differential voltage outputs. This circuit converts the differential voltage output of the DAC to a single-ended, ground-referenced signal and provides the additional current necessary for low-impedance headphones. Project …
