RT Journal Article SR Electronic T1 Design principles for open source bioinstrumentation: the poseidon syringe pump system as an example JF bioRxiv FD Cold Spring Harbor Laboratory SP 521096 DO 10.1101/521096 A1 Sina Booeshaghi, A. A1 da Veiga Beltrame, Eduardo A1 Bannon, Dylan A1 Gehring, Jase A1 Pachter, Lior YR 2019 UL http://biorxiv.org/content/early/2019/01/17/521096.abstract AB The poseidon syringe pump and microscope system is an open source alternative to commercial systems. It costs less than $400 and can be assembled in under an hour using the instructions and source files available at https://pachterlab.github.io/poseidon. We describe the poseidon system and use it to illustrate design principles that can facilitate the adoption and development of open source bioinstruments. The principles are functionality, robustness, simplicity, modularity, benchmarking, and documentation.
