SOIL MOISTURE SENSOR COATING LESSONS LEARNED THE HARD WAY

Ever wanted to measure soil moisture? Common “soil moisture meter module arduino raspberry compatible free shipping” PCBs might deceive you with their ascetic looks. Today, [Raphael (@rbaron_)] is here to teach us (Twitter, unrolled) what it takes to build a soil-embedded sensor that can actually survive contact with a plant. As the picture might hint, waterproofing is of […]

DIY Current Sensor – 2.0

Sensor – Transducer – Detector Projects / By Tismail

Hello there! I hope you all are fine and in good health. This instructable is about making your own current sensor that is compatible with Arduino and most other widely popular microcontrollers. This project features a compact design and an all SMD component based circuit, making this sensor module very compact for it’s range. This

FAIL OF THE WEEK: ALTERNATOR POWERED ELECTRIC GO-KART DOESN’T GO

Arduino News / By Tismail

What do you give a six-year-old who loves going fast but doesn’t like loud noises? Convert a gas go-kart to electric of course! (Video, embedded below.) That goal started [Robert Dunn] of Aging Wheels down a long path toward a go-kart that almost, but doesn’t quite… work. If you’ve watched any of [Robert’s] videos, you know

What Does a Current Clamp Do?

Blog / By Tismail

Definition A current clamp is an instrument used to measure the number of amperes passing through a conductor. The electrical device comes with jaws that open when brought close to the electrical conductor to allow it to clamp. This feature eliminates the need for the current clamp to make physical contact with the current-conducting wire

ECG PROJECT WITH ALL THE MESSY SAFETY DETAILS

Arduino News / By Tismail

We’ve seen a number of heart rate monitoring projects on Hackaday, but [Peter’s] electrocardiography (ECG) Instructable really caught out attention. If you’ve followed Hackaday for any period of time, you’re probably already somewhat familiar with the hardware needed to record the ECG. First, you need a high input impedance instrumentation amplifier to pick up the millivolt

DIY Adjustable Constant Load (Current & Power)

Other Projects / By Tismail

In this project I will show you how I combined an Arduino Nano, a current sensor, an LCD, a rotary encoder and a couple of other complementary components in order to create an adjustable constant load. It features a constant current and power mode and can handle a maximum of 30V and 20A if your

Realistic LED Candle

LED Projects / By Tismail

If you’ve even seen a fake candle you have probably noticed how it doesn’t look realistic. Whether you’re trying to add some atmosphere to a dinner or light up a jack’o-lantern, your choices are limited. A real candle has a fire hazard, but a fake candle will look tacky. If only there were a safe

Arduino Zener Diode Tester

Other Projects / By Tismail

Zener Diode Tester is controlled by Arduino Nano. Tester measure breakdown Zener voltage for diodes from 1.8V to 48V. Dissipation power of measured diodes could be from 250mW to a few Watts. Measuring is simple, just connect diode and press button START. Arduino Nano gradually connect range of voltages from lower to higher, in four
