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.

This is a little diorama made with Arduino for a school project. What happens is a party which just stops playing music. As the sound stops there’s a bright light which turns on. There are two partypeople. One is having a stroke or something because of the alcohol. The other one thinks ‘Dam’n, the party
Party’s Over! Continue Reading
Exactly a year ago (February 2020), James’ wife wanted to expand her plant growing setup in the house. This included a bigger, larger, taller plant growing area AND the need for more lighting. BINGO! The seed for the Idea was planted. After an exhaustive market research, not able to find the product that we had

Most clocks these days have ditched the round face and instead prefer to tell time through the medium of 7-segment displays. [mihai.cuciuc] is bringing the round face to digital clocks with his time-keeping piece, MakeTime. MakeTime serves two purposes, the first and most obvious one is as a clock. Rather than displaying the time with digits,
