Update! Here is a post with the BOM for the project. Sometime ago I came across the Arducam Mini which is quite a nice camera module from UCTronics. It is a small PCB with a two megapixel OmniVision OV2640 sensor, an interchangeable lens and an FPGA to do the heavy lifting of image processing and JPEG […]

Hi everybody, my name is Michiel and I am going to show you how to make an awesome looking laser engraver! A couple of months ago, there was a CNC challenge here at instructables, while checking out the entries of that contest, I saw some pretty cool engraving machines and I thought: “Why shouldn’t I

What if you could cure blindness as easily as turning on the lights? That’s what one doctor and his team are hoping to achieve with a clinical trial that uses a new form of retina implant to return sight to patients who have lost the ability to see. And for one of the six patients,

A new “all-climate” lithium-ion battery can rapidly heat itself to overcome freezing temperatures with little sacrifice in energy storage capacity and power, researchers say. This advance might enable applications for which high-performance batteries are needed in extremely cold temperatures, such as electric cars in cold climates, high-altitude drones, and space exploration. EC Power is now

Among my recent electronics purchase spree was the amazing Teensy LC from PJRC. It has a nice ARM Cortex-M0+ processor, real hardware USB, and what’s the nicest part, an Arduino add-on called Teensyduino which enables easy programming with Arduino, but with support for many of the hardware features. Now I started playing piano a while

In this instructable, I’ll show you how to make a simple Arduino voltmeter. It can measure voltages in excess of 30VDC depending on how you configure it. The smaller the voltage range you want to measure, the more accurate that your meter will be. This project is going to be apart of a gauss meter

This week I have been working on another of my standard footprint 50mm x 50mm boards – it is a general purpose wireless module carrier board:- Fobble. That’s a BLE Fob – for anyone who misses the pun. In the last few weeks there have been a number of applications arise – that could easily

This a door lock built as fun project. It is quite easy to build and a fun way to learn and improve your knowledge of Arduino. I tried to add a 16*2 display but there weren’t enough GPIO pins on Arduino Uno. If You are interested in adding a display you would need an Arduino

How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form multiplexers, which are combined into adders, and finally form the bit counter. The ARM1 is the ancestor of the processor

I learnt about Arduino 2 years ago.So I started playing around with simple stuff like LEDs,buttons,motors etc.Then I thought wouldn’t it be cool to connect to do stuff like displaying the day’s weather,stock prices ,train timings on an LCD display.I found that this could be done by sending and receiving data through the internet.So the
