Building a CNC plasma cutter at home is as awesome as it sounds, albeit a little dangerous. The torch’s 20,000 ℃ plasma stream can slice through any conductive metal. When the positioning of this incredibly hot stream is controlled by a CNC machine remarkable designs can be cut out of metal.

A computer controlled (CNC) mill can turn digital 3D models into metal parts with ease. In this project, Dr. D-Flo converts a manual Precision Matthews mill (833T) to CNC by swapping in ball screws and stepper motors. Learn about the mechanics, electronics, and software behind this project.

Independent Dual EXtruder (IDEX) 3D printers achieve the highest quality when it comes to multi-material or multi-color prints. In this project you will learn how to build Zidex, a small format IDEX printer that is packed full of features. This project goes hand in hand with the How to Build a 3D Printer Guide.

Dr. D-Flo's favorite arcade game is Centipede. He wanted to build a retro upright cabinet but this idea was nixed due to cost and space. Instead, Dr. D-Flo constructed a small bluetooth box with a track ball and a few arcade buttons. Now he can play Centipede comfortably from his couch.

Dr. D-Flo spends a lot of time at the computer when researching and editing videos. A proper desk can make these long computer sessions comfortable and efficient. Dr. D-Flo's steel and marble desk was designed to be ergonomic but also minimalistic to prevent distractions while working.

While calling this machine a food printer is definitely a stretch, think about all of the applications that could benefit from the precise placement of paste. Whether you want to create a work of art on a cake or precisely place solder paste on a circuit board, this project could be of great interest to you.

A beer pairs well with many activities, such as watching a football game or socializing with friends. Beer from a keg not only tastes better than bottled or canned beer but is also cheaper. The challenge with kegs is keeping them cold but also accessible. Enter the Kegerator (Keg + Refrigerator).

Dust off your 3D printer, pick up a motor, and a couple of bearings and you are ready to create this slick cooling contraption. You mind find this project a little controversial because an impellar hidden in the base is what generates the airflow, which definitely has "blades".

Need a helping hand? A 6-axis robotic arm should do the trick. This almost entirely 3D printed arm uses 7 stepper motors and 1 servo motor for 6 degrees of movement plus a gripping action. The arm can be programmed by a Xbox controller to quickly teach it movements.

The magnetic bottle opener has always been a crowd-pleaser. People always seem to be amazed when a tumbling bottle cap is caught midair by a magnet hidden within a wooden plaque. In college, Dr. D-Flo sold hundreds of custom wall-mounted bottle openers and the profits fed his tool buying addiction.

Is this clock analog, digitial, or something else entirely? This unusual way of telling time can only be described as art. In this project, Dr. D-Flo uses his CNC router to mill the clock's aluminum face, HDPE body, and circuit board. An Arduino controls addressable LEDs to light up the appropriate times.

A syringe pump may seem like it is only useful in a hospital or laboratory, but there are many instances where the automatic dispensing of liquids and gels would be very useful. Dr. D-Flo is going to use his syringe pump in a 3D food printer to create tasty works of art.

The MakerGear M2 has been Dr. D-Flo's workhorse of a 3D printer. Its time to give ol' reliable an upgrade by adding a second extruder that can be used for multi-color or -material prints. In this project, Dr. D-Flo also attempts to print a circuit board with conductive filament.

Are 3D printers capable of self replicating? To answer the question everyone is asking, Dr. D-Flo will attempt to 3D print a 3D printer. This paradox of a project will include 3D printed rails, supports, and many other parts. To put it to the test, the 3D printed 3D printer will be tasked with printing its own parts.

Large LED displays can suffer from signal noise and power supply issues. This project will show you how to create an LED system capabale of supporting well over 1000 LEDs that will not only provide more immersive light shows but can still be programmed with the Arduino IDE.

January 7, 2017

Are you interested in learning how to program addressable LEDs? This project will show you how to quickly set up a small lightshow with a strip of addressable LEDs and an Arduino. If you are new to coding or microcontrollers (e.g. Arduinos), then working with LEDs is great way to get your feet wet.

The nixie tube clock is simultaneously old-fashioned and futuristic. Nixies are vacuum tubes that were used as numeric displays in early digital equipment (1950s). Today, these steampunk clocks are statement pieces for those who are unhappy aesthetics of digital displays.
