Hard Drive Centrifuge Rotor (secure design)
thingiverse
My laboratory has been crying out for a compact centrifuge that can handle 1.7 mL Eppendorf tubes efficiently.\r\n\r\nBuilding on KemFic's groundbreaking DIY Arduino-powered centrifuge from old hard drive spindles, I revamped the design to create a more robust structure that fits perfectly onto a standard 3.5" hard drive, expertly molded to match the spindle shape and screw-hole locations. This modification has resulted in an ultra-stable device capable of withstanding higher RPMs.\r\n\r\nThe code has also undergone significant changes (https://github.com/ekurt1/Hard-Drive-Centrifuge), featuring automated and manual speed calibration options, along with ongoing work on RPM vs G-force readings and a vital emergency shutdown mode. Furthermore, the code has been tailored for our specific needs in utilizing a server hard drive, capable of reaching speeds of up to 15,000 RPM.\r\n\r\nThe final tasks to complete the build are designing a secure, weighted enclosure that can withstand the intense vibrations during operation.
