Nyx Tracker for widefield Astrophotography

LabOnTheCheap posts tend to be microscopy heavy, but what about microscopy’s extroverted cousin, telescope photometry? One issue while taking long exposures of celestial objects is tracking their diurnal motion in the sky as the earth rotates. Robust tracking mechanisms start at around ~$300 and quickly go up in price for more accuracy and heavier telescopes. […]

Open-Source Potentiostats for Electrochemical Detection

Potentiometry measures the potential difference between an indicator electrode in a solution and a reference electrode. This provides a quantitative non-destructive measurement of a liquid sample. A common electrode is the glass-membrane electrode used in a pH meter., but various indicator electrodes are designed for specifically for various solutions. The potentiostat is an unloved staple in most wet-labs […]
