Maker creates a fun waveform generator with Arduino

Inspired by a project he found over on Instructables, Maker JoEtuuube has created an Arduino-based waveform generator using an 8-bit resistor ladder DAC that can precisely produce different common waveforms at frequencies between 1Hz and 20Khz in sine-wave, sawtooth, triangle and various ratios of square wave. It features a speaker and a small LCD display. A neat thing about the LCD is that it’s actually […]

A 3D-printed, LEGO-like system for chemistry and biology

A team from the University of California, Riverside has developed a LEGO-like system of blocks that enables users to make custom chemical and biological research instruments quickly, easily and affordably. The 3D-printed blocks can create various scientific tools, which can be used in university labs, schools, hospitals, or anywhere else. The blocks–which are called Multifluidic Evolutionary Components (MECs)–are described in […]
