Potentiostat dummy cells

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 integers read from the ADC (analog to digital converter) at the output of the transimpedance amplifier (current to voltage converter). These integer values are proportional to the current flowing into the working electrode. To convert these unitless integer values to current measurements you need to use a calibration. This can be done using a dummy cell consisting of a single resistor of known value R.  We recently designed a potentiostat...

Online Forum launched

Online Forum launched

We have launched a new online forum: http://forum.iorodeo.com.  Our aim in launching this Forum is that over time it will become a valuable resource for people interested in open source science equipment and DIYBio and grow to become a place to view frequently asked questions and discussions about our products. Hopefully it will also serve as a place to learn about us and what projects we are working on ! While we prefer and encourage general questions about our products on this public Forum, we do also still have a private Contact Form where you can get in touch with...

Using an imaging enclosure for photographing gels

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 with a transilluminator, camera and suitable filters. In research, teaching or DIYBio labs, finding a suitable light-tight box can be the most challenging part of this set-up. We have designed a simple and cheap imaging enclosure (i.e. light-tight box) which works really well for imaging gels with transilluminators. The enclosure is made from machined 0.25" thick black ABS parts (design files are open source and on our...

Welcome to our new Online Store !

We first launched the IO Rodeo online store in April 2010. This week we upgraded our online store to improve the overall customer online shopping experience as well as to improve the site design and appearance (including on mobile platforms). The previous IO Rodeo website is still available for browsing and is archived at www.archive.iorodeo.com. We will keep this site available for access to previous documentation (though we are no longer taking orders on the archived site). Feedback or questions are welcome here: Contact Us Thank you and we hope you enjoy browsing our new site !
