Seven open hardware projects working to solve COVID-19

Chai’s Open qPCR device uses polymerase chain reaction (PCR) to rapidly test swabs from surfaces (e.g., door handles and elevator buttons) to see if the novel coronavirus is present. This open source hardware shared under an Apache 2.0 license uses a BeagleBone low-power Linux computer. Data from the Chai Open qPCR can enable public health, civic, and business leaders to make more informed decisions about cleaning, mitigation, facility closures, contract tracing, and testing.
