Recently I saw a documentary about the history of the television. And to my surprise they showed that there existed a mechanical television before the well known CRT televisions. Those mechanical televisions or televisors were pretty smart and simple. A CRT is simply an electron beam that scans a surface covered with a luminescent phosphor line by […]

Automotive lighting as an important safety and popular design feature in vehicles has evolved rapidly in the past years. Now, Nichia Corporation and Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) start a collaboration to add further momentum to this evolution. Together, they are developing a high-definition (HD) light engine with more than 16,000 micro-LEDs for front light applications. Unlike current
Universal remotes are a handy tool to have around if you have many devices that would all otherwise have their own remote controls. Merging them all into a single device leads to less clutter and less frustration, but they are often not truly “universal” as some of them may not support every infrared device that

One of the joys of being a Maker and Hacker is solving problems and filling needs. When you can do both, well, that’s something special. [rodrigo.mejiasz]’s project surely fits into that special category of solving a problem and filling a dire need with his Bedridden Patient Monitor. While [Rodrigo]’s project page does not specify his motivation

Multiplexing is a very old technology in which control signals are intermixed for the sake of being able to control more devices than there are control signals. For [mihai.cuciuc], the problems started when he multiplexed some very efficient LEDs. The problem? In two banks of six LEDs each, both LEDs connected to a single Arduino pin would light,

[JanHerman] knows that tuning musical instruments is all about precision and that precision is measured in a logarithmic unit called a cent. A cheap tuner unit might be accurate to 1.5 cents which sounds good until you look at one for ten times the price and find it is accurate to 0.1 cents. So you

When you need to get some tasks done and are short on attention, it’s hard to beat a timer. But whenever you do, it feels pretty darn good. The problem is that when you don’t finish in time, what’s the punishment? There are no consequences baked into the Pomodoro Technique other than good ol’ guilt.

Many of us have marveled at art installations that feature marbles quietly and ceaselessly tracing out beautiful patterns in sand. [DIY Machines] is here to show us that it’s entirely possible to build one yourself at home! The basic mechanism is simple enough. The table uses a Cartesian motion platform to move a magnet underneath

Since getting an Arduino starter kit I was wondering what to make of all those fancy buttons, shiny LEDs, touchscreen LCD displays… I was thinking about weather station, but I was told that in the maker’s world, weather station is like a “Hello World” app. Like playing “Stairway to Heaven” in a guitar store. Then, when

Tic Tac Toe is a two player game in which the players compete to get 3 pieces in a row. In this project we constructed a Tic Tac Toe game using a number pad and neo pixels as pieces. This results in a portable Tic Tac Toe game requiring only a wall outlet to play.
