A magnetic stirrer uses a rotating magnetic field to mix fluid samples, such as buffers and media for growing bacteria. Since only a small magnet bar has to be put inside the sample/fluid, the risk of contamination is minimized. For protein purification, overnight sample dialysis steps often utilize magnetic stirrers. Below are beta release DIY […]
The TR pcb mountable pressure transducer series from Merit SensorTM is a rugged, direct-media pressure monitoring solution designed for today’s toughest pressure sensing environments. This pressure transducer series offers a pressure range from 15psi to 500psi with a fully compensated amplified output. The TR series from Merit SensorTM is designed for air, liquid and gas harsh media

Trandi blogged about his RC servo and stepper motor project. He writes: For those interested in reproducing this example: The board is called “EP2C5 Mini Board” and has a EP2C5T144C8 Cyclone II FPGA on it I used a standard, 9grams micro RC Servo I used a 28BYJ-48 stepper motor and it’s driver (you can purchase these

Leveraging the natural adsorption–desorption exchange of water molecules from ambient air at the interface of a nanoporous mesh of protein nanowires, a team of researchers from the University of Massachusetts has demonstrated a durable form of energy harvesting that could potentially compete with solar cells on volumetric power density. By Julien Happich @ eenewseurope.com Publishing their

One of the best things about being a maker is the ability to make your own tools. We have covered the development of several electronics tools in past, from voltmeters to battery testers. For today’s tutorial, we will add another tool to the list by examining the development of a Miliohm meter made by danielrp @ www.instructables.com A milliohm meter

The recent moves by Sonos can only be explained as targets towards expanding its connected ecosystem of smart devices and beyond. The wireless speaker company from Santa Barbara California, sometime last year acquired a French company that provides embedded assistants and interfaces for devices that run locally and offline. Of recent, the company set out to add to

Introduction Some times there is a need of remote controlling electrical devices through local network or Internet. This circuit comes to cover that need. This circuit was initially designed to remote turn on or turn off the central heating system of a building and simultaneously provides the temperature and humidity values of the room where this
F&S Elektronik Systeme GmbH presents a prototype of a direct solder module. It’a a 30 x 30mm “OSM-MX8MM” module that runs Linux on an i.MX8M Mini. As part of the SGET, the standardization group SDT.05 was founded jointly by iesy GmbH, F&S Elektronik Systeme GmbH and Kontron AG. The aim of this group is a new standard

Make your own dual programmer in AVRDUDE Modified 9/16/2014 Those of you who have programmed an Arduino through the Arduino or AVR Studio IDE may have noticed the utility that is really doing the work: AVRDUDE (AVR Downloader/UploaDEr). This is a powerful program that can facilitate programming new sketches on top of a bootloader, load
I’ve had a CNC mill for a few years now, and while many homemade CNC mills use EasyDriver or Pololu, mine came with a sturdy, generic TB6560 controller board. For those unfamiliar, boards like this are interfaced using an old fashioned LPT parallel port, which was initially an annoyance, but quickly became impractical and a
