Measuring the speed of light with electronics
Posted on: 10 Oct 2017
The speed of light in vacuum is a well-known universal constant and is considered to be the nature’s ultimate speed limit. No matter, energy, and information can travel faster than this speed. The speed of light has always been a topic of great interest and significance throughout history. In the course of measuring the speed […]
Arduino Without External Clock Crystal on ATmega328
Posted on: 09 Oct 2017
Story An Arduino consists of many components like: a linear regulator, USB to Serial microcontroller, debug LED, power LED, reset button, RX & TX LED, crystal oscillator, etc. But a minimal circuit can have just the brain of the Arduino UNO, that is, an ATmega328p microcontroller (Reducing Arduino Power Consumption). You can assume this one […]
LTC3623 – Switching regulator doubles as Class-D audio amplifier
Posted on: 09 Oct 2017
Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a reproducible way and without making things overly complex requires some serious head scratching. The anxiety may be reduced vastly though by a new adjustable synchronous buck regulator which uses a single […]
Reducing Arduino Power Consumption
Posted on: 08 Oct 2017
Story When it comes to portable electronics, one of the most important features is how to maximize the battery life. The ATmega328P, used on popular boards like the SparkFun RedBoard, Arduino Uno, and Pro Mini are actually quite power hungry. The RedBoard and Arduino Uno, draw around 15mA minimum, which doesn’t sound like much but […]
Chronio – Low power Arduino based (smart)watch
Posted on: 08 Oct 2017
Description Chronio is an Arduino-based 3D-printed Watch. By not including fancy Wifi and BLE connectivity, it gets several months of run time out of a 160mAh button cell. The display is an always-on 96×96 pixel Sharp Memory LCD. If telling the time is not enough, you can play a simplified version of Flappy Bird on […]
Gimmick on Barebones Arduino 16MHz
Posted on: 07 Oct 2017
Story Did you see this 8MHz no-crystal Arduino? Arduino on Internal Oscillator Crystal as Clock Source by Naman Chauhan is a great project if you can live with 8MHz using the internal RC oscillator of the Atmega328P chip. I really like Naman’s project; I did my own version of the 8MHz Arduino many years ago […]
16×32 RGB Matrix Panel Driver Arduino Shield
Posted on: 07 Oct 2017
Our RGB matrix panel driver shield for Arduino Uno has been slightly revised. The shield now also carries the DS1307 RTC chip on board along with a CR1220 coin cell battery holder on the back. It is applicable for driving popular 16×32 RGB matrix panels with HUB75 (8×2 IDC) connectors. Row and column driver circuits are already […]
Tri-Mode Digital Clock with ATtiny85 and RTC
Posted on: 06 Oct 2017
Story Hello everybody, This is my first project using ATtiny85 microcontroller and also including a Real Time Clock (RTC) working with it. The use of ATtiny85 is a very interesting way to shrink your Arduino projects in a final tiny version. The Three-Modes Digital Clock includes a version with common decimal clock and also with […]
Test application for the FPGA Tibbit in the smart LED controller configuration
Posted on: 06 Oct 2017
You will need: TPP2, TPP2(G2), TPP3, or TPP3(G2) board One Tibbit #57 One Tibbit #20 Optionally, one Tibbit #00-3 (if you are going to power your smart LEDs from your TPS system) Several SK6812RGBW LEDs (or a board, or a LED strip containing these LEDs) Optionally, one Tibbit #10 (12V->5V regulator) Optionally, one Tibbit #18 […]
