Building a DIY Centrifuge For Blood Processing
Thomas Nguyen constructed a custom DIY centrifuge to separate T cells from blood for laboratory analysis. The device utilizes a Raspberry Pi Pico, a 3D-printed frame, and a brushless motor to achieve the necessary rotational speeds. Safety mechanisms including vibration detection and speed monitoring are integrated to ensure safe operation during testing.
- ▪Thomas Nguyen built the centrifuge to handle 15 mL conical tubes for T cell separation.
- ▪The build incorporates a Raspberry Pi Pico and an A2212 brushless motor with a 30 amp electronic speed controller.
- ▪An MPU-6050 sensor is used for vibration detection to shut down the unit if dangerous imbalances occur.
- ▪An IR sensor monitors and controls the rotational speed of the centrifuge.
- ▪The project is currently in development, with initial tests planned using dyed water and glycerol before using real blood.

Building A DIY Centrifuge For Blood Processing No comments by: Zoe Skyforest September 17, 2026 Title: Copy Short Link: Copy If you want to do certain types of lab work with blood, you’ll need a centrifuge. It’s often possible to find serviceable units on the used market, but they may not meet your requirements if you’re doing something quite specific. For that reason, [Thomas Nguyen] decided to build his own centrifuge from scratch. His goal was to separate T cells from blood for further lab analysis, and he needed to be able to work with blood in 15 mL conical tubes. Capable centrifuges weren’t affordable, but he figured he could build his own quite easily. To that end, he enlisted a Raspberry Pi Pico, a 3D printer, and an A2212 brushless motor with a 30 amp electronic speed controller.
