### Background

- Nice wikipedia description of what a potentiostat is [here](http://en.wikipedia.org/wiki/Potentiostat).

- CheapStat -- PLOSOne article [here](http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0023783) -- they use a DIY design to assess ascorbic acid in orange juice, cyanide in water, acetaminophen content of over-the-counter pain medication, and arsenic in water.  Neat!

### Uses

- Assess arsenic, cyanide, other contaminants / toxins in water
- Educational
- Identifying toxins / ingredients in foodstuffs

### Development

- [olm-pstat](http://github.com/cversek/olm-pstat) - repository for the PLOTS/[PVOS](http://www.pvos.org/) Open Lab Monitor potentiostat peripheral
