Poseidon is a well documented open source microfluidics and imaging system consisting of a set of three DIY syringe pumps for $180 and a compatible microscope for $220. Poseidon is documented in a paper on BioRxiv by A. Sina Booeshaghi, Eduardo Beltrame, Dylan Bannon, Jase Gehring, and Lior Pachter . In the paper, the system is benchmarked to Harvard Apparatus […]

OpenFlexure Block Stage: 3D printed sub-micron mechanical precision
OpenFlexure Block Stage is a 3D printed flexure translation stage with sub-micron mechanical positioning. You can get the files to build it on GitHub. The project is 3-axis, short travel, high accuracy spinoff from the stage of the amazing OpenFlexure Microscope which we still haven’t covered, but we thought this stage deserved a post of its […]
Smartphone spectrophotometer for less than $6
We’ve covered smartphone florescence spectroscopy before, and we also have a post on building your own Lego spectrometer. In a similar vein check out a dedicated spectrophotometer detailed in a paper by Vasco Pereira and Bill Hosker. Maybe. The paper covers a 3D-printed version and teases a Lego constructed version. Either way, you have a […]
OptiJ: Open-source optical projection tomography for $3000
Optical Projection Tomography (OPT) is a microscopy technique suited to mostly transparent specimens of ~10 mm. OPT requires the collection of a number of images (projections) of a sample taken from different angles. In practice, this means as rotating a sample around an axis in a precise manner. These images can be fed into mathematical […]
GridTape: cutting the cost of serial section Transmission Electron Microscopy systems
GridTape is part of a new system for serial section transmission electron microscopy imaging which excels at high-throughput low-cost nanometer-scale transmission of large volumes. And it’s cheap, for the current price of a comparable multi-beam SEM system, ten grid-tape TEM systems can be built. At first glance the cost sheet looks imposing, but it contains […]
