A 3-D printable open source platform for fluorescence microscopy, optogenetics and accurate temperature control.
By A Maia Chagas, LL Prieto Godino, A Arrenberg and T Baden
Designed for flexibiliy and low-cost, the “FlyPi” is an optical microscope designed for behavioural work with fruit flies, zebrafish or C. elegans.
The system is based on a Raspberry Pi with camera, an Arduino microcontroller and a range of off-the-shelf electronic parts. A modular design provides for flexible control of a range of peripherals including options for optogenetic and thermogenetic stimulation and fluorescence microscopy. All mechanical parts are 3-D printed which includes a range of manual or motorised micropositioning options.
The basic setup can be put together for below 100€. The low price means that it can be implemented in under-funded labs across the world, for classroom teaching in schools as well as by home-enthusiasts who are not part of the traditional scientific establishment.
The MS, including complete build instructions and BOM is published at PLoS Biology (open access):

Rather than building all from scratch yourself, you can soon also buy one or get a bag of parts: Have a look at Andre’s new startup Prometheus Science!
