DIY Raspberry Pi 4 Desktop Case With OLED Stats Display

by

In this video, I’ll show you how to make your own Raspberry Pi 4 case which looks like a Mini Desktop Computer. The case houses the Raspberry Pi 4 with an Ice Tower fitted for cooling and has a small OLED display on the front which shows the computer’s IP address as well as some stats on the CPU, memory, and storage usage as well as the CPU temperature. The power, HDMI, and audio ports are accessible on the side and the USB and Ethernet ports are accessible on the front of the case.

If you’d like to build your own case, here is the step by step guide with the 3D print file, side templates, and code – https://www.the-diy-life.com/diy-rasp…

I Finally Got my Atari VCS! (Console Review)

by

UPDATE: The issues with downloading Vol. 2 have been resolved, at least in my case. I’m fully aware this video may not age well. So, I guess I was at the top of the shipping pallet, because I got my VCS less than 24 hours after they started shipping. I was the first person to post online that I had one, and Atari actually tweeted my photo as a result. This is a bite-sized review of my honest day one experience. I did not get to talk about everything I wanted to, but I did what I could.

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

by

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.

SNES Rainbow Road – Mario Kart Live: Home Circuit (Switch)

by

I’m back at it again and this time I decided to make Rainbow Road on the SNES in real life for my next Mario Kart Home Circuit track. I hope you enjoy the time, money, and effort I put into this course. I even made the track have a chasing rainbow led pattern and two mechanized Thwomps on the course’s split. I will be posting a making of video for this course and I will pin the link in the comments.

An Arduino Based Laser Guitar

by

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

by

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

by

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.

Jozef Bogin Boots an IBM PC From an Unusual Medium: A Vinyl Record

by

Taking advantage of the IBM PC’s cassette deck interface and a vinyl cutter Bogin may now own the only IBM compatible to boot from a record.

Engineer Jozef Bogin has taken on an unusual challenge: Getting a computer to boot from a vinyl record, played at 45 revolutions per minute.

Today, most computer systems use magnetic or solid-state media for their storage — hard drives or solid state drives. In the early days of computing, though, cassette tapes were not uncommon — storing the digital data as audible beeps and boops which could be played back on any standard cassette deck. That link between audio and digital data gave rise to programs distributed on the flip-side of cassette albums, and in a few unusual cases programs which could be played back on the B side of vinyl records.

SS4H-SD Smart Doorbell – DIY project based on ESP32

by

You surely know this feeling when the doorbell rings while you are doing something interesting: watching a movie, playing a video game, or spending a romantic evening with your loved one. And when it turns out that this is an uninvited/unwanted guest, you get even more pissed off.

Of course, you can ignore it and not open the door, but there will always be this hint of uncertainty – “maybe it was important”.

The solution to this problem is the “smart doorbell”. Thanks to it, you’ll know if it is worth getting up from the couch and opening the door or not.
