How does a tiny chip time the runners in the Bay to Breakers race? In this article, I take die photos of the RFID chip used to track athletes during the race. Bay to Breakers is the iconic San Francisco race, with tens of thousands of runners (many in costume and some in nothing) running […]

Monitor your crypto mining hardware temperatures and hash rates with the ability to restart the rig remotely as well as Alexa integration. Things used in this project Hardware components Arduino MKR1000 × 1 Raspberry Pi 3 Model B × 1 Temperature probe (ds18b20) × 5 Resistor 4.75k ohm × 1 Amazon Alexa Echo Dot ×
The “ESP8266 OLED SSD1306″ is an open source library which allows you to control those pretty OLED modules from our beloved ESP8266 module. Fabrice Weinberg cleaned up all the ugly pieces of code which I initially wrote caused by my near C/C++ illiteracy. He also added support for Pasko’s BRZO I2C library which is partially written in assembler and
The new digital SHT3x humidity sensor series takes sensor technology to a new level. As the successor of the SHT2x series it is determined to set the next industry standard in humidity sensing. The SHT3x humidity sensor series consists of a low-cost version with the SHT30 humidity sensor, a standard version with the SHT31 humidity sensor,
Despite its popularity among hobbyists and electronics enthusiasts, the Arduino has become infamous among professional embedded systems developers. I must admit that for the longest time I also viewed the Arduino as so simple it was nearly useless for professional developers. But I have changed my mind. I’ve found that on a number of occasions
Prototype to production: Arduino for the professional Continue Reading
Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the
Introduction Besides looking damned good on an otherwise bland and ordinary desk, this project is about more than just being attention grabbing eye candy. It’s about demonstrating a small portion of our single board computer capabilities by hooking up a color sensor, RGB light strip, and enclosing it in a nice looking wooden enclosure. We’re

Monocle enables Alexa devices such as Echo Show/Spot & FireTV to view your network IP cameras & control them with a wireless PTZ controller. Story Amazon Alexa® (at least at the time of this writing) does not inherently support any direct integration with local/private network cameras running securely inside your network. Instead Alexa focuses on
