Skee-ball-like indoor golf game gets an automatic scoring system

After making an indoor Executive Par 3 golf game with a ramp and cups like a skee-ball machine, creator “gcal1979” decided to add an automatic scoring system to the rig.

What he came up with uses infrared break beam sensors for each of the three holes, feeding info to an Arduino Mega. Stats are shown on an electronic scoreboard behind the play area, with a seven-segment display for the hole number, as well as two four-digit units for player scores.

Arduino-based machine makes cutting and stripping wires easy

If you need to strip a wire or two, that’s easy enough. However, what if you need tens or hundreds of wires stripped to the exact same length? Such a task would quickly become tedious, but with Mr Innovative’s Arduino Nano-based machine all you have to do it pop in a few numbers and it takes care of the rest!

The automated device uses a 3D printer-like stepper mechanism to feed wire though a flexible length of tubing, which comes out on the other side positioned under a wire stripper. A servo is employed to aim the tubing and wire at either the cutting or stripping portion of the tool, which clamps down via a stepper and linkage setup. User interface consists of a 2.8″ touchscreen, allowing one to define the wire and stripped lengths, as well as how many individual wires are required.

Debra Ansell Is Quickly Becoming the “Go-To” Authority on Great-Looking LED Lighting!

It’s almost a guarantee that if you haven’t yet incorporated the ubiquitous WS2812x ‘NeoPixel’ or APA10x ‘DotStar’-style “digital” LEDs into a project, you will no doubt have seen the myriad works of many a maker, ranging from blinking, bedazzling digital jewelry to drive-in scale digital LED video walls.

No matter the form factor, getting these bare LED emitters to look their best can sometimes take quite a bit of work! A range of factors, from ensuring that you have provided an adequate power supply to diffusion of the light emitted from these devices — and everything in between! — means that there is usually a direct trade-off between the amount of thought that goes into the incorporation of these LEDs, and how fantastic the final product looks!

Biorhythm Clock using Arduino Nano, RTC, 1602A Display, 74HC595

It’s a biorhythm clock using Arduino Nano A biorhythm is a theoretical process by which the human body and mind are regulated according to set patterns. Biorhythms are usually separated into three distinct groups. The emotional, mental, and physical cycles. Classically, the lengths of these cycles are 28 days, 33 days, and 23 days respectively.

An Arduino Based Laser Guitar

Our love for music was not enough for us to learn playing instruments except for a few basics of guitar and saxophone. The background in physics we had pushed us to delve into incorporating technology and music together. We thought of the possibility of enhancing the guitar, the most famous instrument of all time. It could outperform the classical guitar with its metal string by creating more flexible options for the player and his/her performance. The project aims to design and build a guitar based on an optical setup built of Lasers, Beam Splitters, and Light sensors. The strings of the guitar will be replaced by an optical setup. The general technique for playing guitar to shorten the string by pressing your hand on the desired fret, and plucking with your other hand the string needed to produce the note or chord you want. If no fret is compressed, it is called an open string. Note that many techniques were invented during the years: Pulling, tapping, sliding, etc… however, we will stick to the standard way of guitar playing.

The design is composed of two modules, mimicking the two main tasks of playing guitar. By receiving certain information, The microcontroller would generate the desired note.

Plottin’ Bottles with a CNC Machine

You’ve probably seen a plotter of some kind made from DVD players and the like. These devices, of course, normally work with objects in the XYZ coordinate system. As cool as they are, TUENHIDIY’s build takes things to another level – or at least in another direction – with a pair of printer rollers subbed in for the Y-axis. This allows a bottle to roll in coordination with an X/Z gantry system on top, decorating it with whatever text or drawings are programmed

These side glow fiber optic panels make beautiful wall décor

Side glow fiber optics – unlike their cousins that efficiently transmit light from one point to another – emit a glow along the length of each strand when light is applied. This creates a beautiful effect, which Andrei Erdei implemented nicely in his wall decoration project.

Erdei’s build consists of a series of nine square frames, inside of which 3mm fiber optic strands are connected, looping gracefully from one edge to another. Each strand is lit by an addressable WS2812B LED module, under the control of an Arduino Nano.

You can see this wall installation in action in the video below, and more info on how to build your own is available on the project write-up.
