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.

Source code and schematics are …read more

Zen and the Art of Arduino

Posted on by

A zen garden should be a source of relaxation and escape from the everyday. The whole point should be to escape from–among other things–your electronics. Unless you are [MakrToolbox]. Then you’ll make a beautiful zen garden end table that allows you to make patterns in the sand using a ball bearing and an Arduino. You can see a video below.

Technically, the device is almost an upside down 3D printer with no Z axis. The mechanism moves a magnet which controls the steel ball and draws patterns in the sand. However, the really impressive parts of this project are the …read more

Safe Cracking is [Nate’s] Latest R&D Project

Posted on by

We love taking on new and awesome builds, but finding that second part (the “awesome”) of each project is usually the challenge. Looks like [Nathan Seidle] is making awesome the focus of the R&D push he’s driving at Sparkfun. They just put up this safe cracking project which includes a little gamification.

The origin story of the safe itself is excellent. [Nate’s] wife picked it up on Craig’s List cheap since the previous owner had forgotten the combination. We’ve seen enough reddit/imgur threads to not care at all what’s inside of it, but we’re all about cracking the code.
