The Nixie tube filadometer – a Nixie tube filament meter for your 3D printer

Dr. Scott M. Baker made a Nixie tube filament meter for his 3D Printer: First, I decided to upgrade from the Raspberry Pi Model B to a more recent Raspberry Pi Zero W that I had on hand. Wired Ethernet is so ~ 2013 after all, and wireless would be a lot more convenient. Next, […]

Custom 3D printed magnetic encoder disks for robotics projects

A how-to on making a custom DIY magnetic disk encoder by Erich Styger: I’m making great progress with the firmware for the new Mini Sumo Robot (see “New Concept for 2018 Mini Sumo Roboter“). The goal is a versatile and low-cost Mini Sumo robot, and the robot comes with the feature of magnetic position encoders. […]

An open source 3D Scanner made with Raspberry Pi

Boris Landoni from Open Electronics writes about a new open source 3D Scanner made with Raspberry Pi: This being said, we may move on to talk about our 3D scan approach, that consists in using a linear laser, that is, one capable of drawing a vertical line having a constant luminous intensity, and in shooting the images that […]

More Delta printer upgrades: WiFi and silence!

David Crocker has been working on his Delta 3D printer project: After performing this upgrade, the printer is much quieter than before. This is because of the change from x16 microstepping on the Duet with A4982 drivers, to interpolated x256 microstepping on the Duet WiFi with TMC2660 drivers. The noisiest component is now the 40mm electronics […]

openSAM: a 3D-printed open source camera stabilizer

OpenSAM by OHM – a 3D Printed Camera Stabilizer: Welcome to OpenSAM, our 3Dprinted self-built three Axis stabilizer. It is handheld and the entire mechanical construct is built using 3D printed parts. Brushless motors ensure the camera is stable and they can be controlled using a joystick. The design is developed by three engineering students […]

An almost reliable, high precision, 3D printer: Son of MegaMax (SoM)

Mark Rehorst wrote this instructable detailing the build of his 3D printer – Son of MegaMax (SoM): I built my first 3D printer, MegaMax, using surplus machine parts over a period of about 2 years. I built it myself because when I started the project, the biggest build envelope you could get in a reasonably priced machine was […]

Arduino-assisted automatic 3D printed tea maker

If the earlier Arduino projects weren’t your cup of tea, try out this Automatic 3D Printed Tea Brewer. 24 Hour Engineer Brian McEvoy designed this project which uses the Arduino to control a servo which dunks the tea bag for a predetermined length of time for perfect brew control. The LCD readout provides information about […]

Build a 16 million color WiFi-controlled LED lamp

Tom Van den Bon and Sebastian Schocke of Binary Space, a makerspace in the Vaal Triangle, have put together this build challenge for their members. For December at Binary Space we wanted to do something a cheerful and colourful. We got together to design and build a low power LED table or ceiling lamp that […]

SpeakerGen – parametric 3d printed speaker enclosures

Rich Olson writes, “I just put together an OpenSCAD script that can generate optimized loudspeaker enclosures based on driver’s audio parameters. Intent of course is to 3d print speaker enclosures…” For more information visit Rich’s NothingLabs blog. Via the contact form.

DiyouPCB low-cost PCB printer for photoresist

Charlie and Victor from Diyouware write, About a year ago my brother and I engaged on a quixotic project to build from scratch a low-cost PCB printer for photoresist. Finally we did it using a Blue Ray optical pickup (PHR-803T) and his UV laser/electronics to sensitize Dry-film. The optical pickup is used through his own […]

An open source, $2000, metal 3-D printer

Open-source metal 3-D printer: This paper reports on the development of a <$2000 open-source metal 3-D printer. The metal 3-D printer is controlled with an open-source micro-controller and is a combination of a low-cost commercial gas-metal arc welder and a derivative of the Rostock, a deltabot RepRap. The bill of materials, electrical and mechanical design […]
