Hard Drive Centrifuge Rotor (secure design) by ekurt64

Last crawled date: 3 years, 1 month ago

My lab has been in need of a compact centrifuge for 1.7 mL Eppendorf tubes.
From the work by KemFic on a DIY Arudino powered centrifuge from old hard drive spindles, I modified the design for a more secure structure and fit on a standard 3.5" hard drive (molded to the spindle shape and screw-hole locations). The resulting structure is more stable at higher RPMs.
The code has also been modified (https://github.com/ekurt1/Hard-Drive-Centrifuge), with automated and manual speed calibration options, with work being done on RPM vs G-force readings and an emergency shutdown mode. The code has also been modified for our purpose in using a server hard drive, with speeds of up to 15,000 RPM.
The remaining tasks for the build are a secure, weighted enclosure (since vibrates heavily during use).
