Soooo….Wifey decided that it was time for a new pet. Spin the wheel….A Spotted Gecko!! Well, Geckos are apparently very temperature sensitive creatures so we invested in a UTH (Under Tank Heatpad) for those of us that are new to the world of reptiles. The purpose of said UTH is to provide warmth from below, to […]
In this project I’m building a physical Twitter client using Arduino and a flag, basically an arduino powered retweet indicator, whenever any of my tweets is retweeted some physical action will happen to notify me of that. You’ll need: 1. Flag. 2. Arduino. 3. Laptop with a java IDE installed on it. 4. Yellow Led […]
The Particle Photon is a microcontroller suitable for wearable project’s considering it’s small form factor and that it supports OTA updates. For those of you who do not know what a Particle Photon is it is a tiny microcontroller with on board WiFi (Cypress WiFi chip) and the STM32 ARM Cortex M3 microcontroller, which is ideal for cool […]
Recently my wife has suggested that I should lose a few pounds in weight (too much time geeking out and not enough time in the gym). With that in mind -and in true nerd fashion- I wanted to create a method to see my progress, as well as having a constant reminder to stick to […]
At milliohm levels the fixture is part of the measurement: contact repeatability, differential ADC settings, settling and the limits of the displayed digits.
Usually inventions are invented to serve a need or to solve a problem. So this small gadget that i constructed came to serve a need of mine.I have a NAS, Atom based file server, that runs on Ubuntu, but from time to time the operating system freezes and i have to cold restart it. The […]
This instructable teaches how to make our Bear With Me system, a prototype that allows two users to tangibly send and receive hugs (as well as motion) in near real-time. The bears will be able to send tweets when physically hugged. Their hearts will glow when they receive the other bear’s hug. The bears can […]
There is a lot of buzz going around Arduino and the series of boards. One of the most used board from the Arduino series is the Arduino Uno. But what many people don’t notice is that there is a board similar to Arduino UNO but has many more features. That board is called Freescale K64F. In this […]
Step 1: The Board & Shields Wemos D1 Mini 11 digital input/output pins, all pins have interrupt/pwm/I2C/one-wire supported(except D0) 1 analog input(3.2V max input) a Micro USB connection Compatible with Arduino Compatible with nodemcu DHT11 Temperature: -20~60°C Humidity: 20-95%RH (±5%RH) It uses D1 and D2 of the WEMOS Board and is extremely popular. They tones […]
In this Instructables, you will see how to Interface Moisture sensor to your NodeMCU. And check the moisture value and the same to be displayed on the LCD. We’ll use Liquid Clear Crystal to display the moisture value. This 16×2 LCD is very popular and broadly used in electronics projects as they are good for displaying information like sensor data from your […]
