Makers and hobbyists searching for a new Arduino project to keep them busy this weekend may be interested in a 3D printed DIY Arduino electric screwdriver created by “Progress Thailand”. The DIY electric screwdriver is fitted with a 9 g Micro server which has been modified for continuous rotation and connected to an Arduino Nano. As you can […]
CO2 Monitoring is mandatory in many workplaces and it affects two of my clients directly in Barrel Halls where wine is stored and aged in temperature and environmentally controlled areas. The table below shows the affects of various concentrations in the air. 250-350ppm Normal background concentration in outdoor ambient air 350-1,000ppm Concentrations typical of occupied indoor
I’ve been stuck in my house filling orders for my Kickstarter campaign for the CAMERADACTYL 4×5 Field Camera, mostly just babysitting printers, changing filaments and adjusting extruders every few hours. This has left me with some rare time for tinkering. Recently I built a cheap, quick and dirty tool to calibrate a project that I was

Infinite Noise TRNG (True Random Number Generator) For instructions for compiling the and using Infinite Noise TRNG driver, go to the software sub-directory, and read the README file there. Both Linux and Windows are supported. The Infinite Noise TRNG is a USB key hardware true random number generator. It uses what I call a “Modular

The main objective of this project is to show how to interface a uCAM-II serial camera to 4Duino. uCAM-II is a highly integrated micro serial camera which could be controlled by any host that requires a video camera or a JPEG compressed still camera for embedded imaging applications. uCAM-II processes various features making it trivial

It’s said that beauty and art can be found anywhere, as long as you look for it. The latest art project from [dmitry] both looks in unassuming places for that beauty, and projects what it sees for everyone to view. Like most of his projects, it’s able to produce its artwork in a very unconventional
Abstract: This article is how-to guide, intended as a quick learning aid for engineers considering using the MAX6954 to drive 14-segment monocolor LEDs. The MAX6954 is a versatile display driver, capable of controlling a mix of discrete, 7-segment, 14-segment, and 16-segment LED displays through a serial interface. This application note shows a typical application and configuration
Driving 14-segment displays with the MAX6954 Continue Reading
How about a cheap serial terminal for less than a fiver all-in? In a previous blog entry I’ve been working on more developments for the increasingly powerful home control system using an Arduino as a kind of universal I2c peripheral to the ESP8266. The reason for that is just the vast range of driver software
Beyond pride, the biggest issue keeping adults off small motorized scooters is the fact that their tiny motors usually don’t have the power to move anything heavier than your average eighth grader. That didn’t stop [The_Didlyest] from snapping up this $7 thrift store find, but it did mean the hot pink scooter would need to be beefed
