pH Featherwing The pH FeatherWing hardware guide The pH FeatherWing is a single channel pH electrode amplifier based on Texas Instrument's LMP7721 ultra low input bias current (3 fA) precision operational amplifier. The design of the pH electrode amplifier closely
pH Featherwing Creating a pH meter using the pH FeatherWing In this blog post we demonstrate how to create a pH meter using the pH FeatherWing, an Adafruit Feather M4 Express and a few additional components. The meter will display a continuous readout
Hardware Electrophoresis power supply - LCD display We have recently updated the electrophoresis power supply to include an LCD display as shown in the images below. The price of the power supply kits remains the same ($65 for a kit)
Hardware Open source potentiostat features In this blog post we give a quick overview of some of the main differences between two open source potentiostats: Rodeostat and Cheapstat.
Hardware Measuring emission spectra for the blue LED transilluminator Our blue LED transilluminators use a 470 nm LED array in combination with blue and amber acrylic filters for viewing DNA bands in agarose gels stained with DNA dyes. Images of gels stained
Hardware IO Rodeo Open Source Potentiostat We have recently been working on a new potentiostat. The Rodeostat (initally referred to as a potentiostat shield) is an open source potentiostat for performing electrochemical measurements which is designed to work with
electrochemistry Potentiostat dummy cells One of our most frequently asked questions on the Forums and via email is how to produce a calibration for the Cheapstat potentiostat. The Cheapstat potentiostat returns measured current values as raw unitless
Hardware Using an imaging enclosure for photographing gels Photographing gels is an important step in research projects that involve any kind of visual or quantitative DNA analysis by electrophoresis. Decent gel imaging requires a fairly simple set-up of a light-tight box
