Open Source Laboratory Rocker is Super Smooth

Posted on by

Lab equipment is often expensive, but budgets can be tight and not always up to getting small labs or researchers what they need. That’s why [akshay_d21] designed an Open Source Lab Rocker with a modular tray that uses commonly available hardware and 3D printed parts. The device generates precisely controlled, smooth motion to perform automated mild to moderately aggressive mixing of samples by tilting the attached tray in a see-saw motion. It can accommodate either a beaker or test tubes, but since the tray is modular, different trays can be designed to fit specific needs.

Soundproofing A CNC Mill Conversion

Posted on by

The Proxxon MF70 is a nice desktop sized milling machine with a lot of useful add-on accessories available for it, making it very desirable for a hacker to have one in his or her home workshop. But its 20000 rpm spindle can cause quite the racket and invite red-faced neighbors. Also, how do you use a milling machine in your home-workshop without covering the whole area in metal chips and sawdust? To solve these issues, [Tim Lebacq] is working on Soundproofing his CNC mill conversion.

To meet his soundproof goal, he obviously had to first convert the manual MF70 to …read more

Go Go Camera Slider

Are your arms getting tired from pushing your camera back and forth across your camera slider? That must be the case with [Max Maker], which led him to convert his manual slider into a motorized one.

The electronics are minimal — an Arduino Micro, a few toggle switches, A4988 Stepper Driver, 12V battery pack, and the ever popular NEMA 17 stepper motor. If you’re wondering why we said ‘switches’ instead of ‘switch’, it’s because 4 of the switches are used to select a time frame. The time frame being how long it takes for the slider to move from one …read more

Hackaday Prize Entry: 3D Printed Linear Actuator Does 2kg+

Posted on by

The rabbit hole of features and clever hacks in [chiprobot]’s NEMA17 3D Printed Linear Actuator is pretty deep. Not only can it lift 2kg+ of mass easily, it is mostly 3D printed, and uses commonplace hardware like a NEMA 17 stepper motor and a RAMPS board for motion control.

The main 3D printed leadscrew uses a plug-and-socket design so that the assembly can be extended easily to any length desired without needing to print the leadscrew as a single piece. The tip of the actuator even integrates a force sensor made from conductive foam, which changes resistance as it is …read more
