Fechko [i]<\/a> built a peristaltic pump (see figure 2) using a Raspberry Pi single-board computer and a standardised T-slot profile construction set called OpenBeam. The pump was designed as a fluid reward system for laboratory animals, but can be adapted for other uses as well.<\/p>\n <\/p>\n Figure 2<\/strong> Raspberry Pi Peristaltic Pump (Photo by AmberFechko, image licensed under the Creative Commons BY-SA<\/p>\n license).<\/p>\n The electronics consist of modular components that do not require soldering. The electronics used are an Arduino or Raspberry Pi and components easily obtained from open-source hardware distributors. Source code is available for Arduino, using a motor shield, and Raspberry Pi, using either a Gertboard or L293D motor control chip. All components used are available off-the-shelf and no special skills are required to build the pump.<\/p>\n <\/p>\n Wijnen et al\u2019s syringe pump<\/em><\/p>\n Wijnen et al published a complete open-source syringe pump library, consisting of a series of 3D-printable parts to build a syringe pump. Performance of the syringe pump was assessed and the methods used for assessment are detailed. The design, bill of materials and assembly instructions are publicly available. The 3D-printable parts can be modified using an open-source parametric 3D design tool, called OpenSCAD [ii]<\/a> and derivatives like OpenPump [iii]<\/a> [iv]<\/a> have already been created.<\/p>\n <\/p>\n To build the device a 3D printer, or 3D printing service, can be used to print the necessary parts. The electronics are based on a Raspberry Pi, stepper motor and driver components that can be obtained from open-source hardware distributors. Most mechanical components can be obtained from a local hardware store. Some specialist components like ball bearings, linear bearings and flexible couplings can be sourced online. Source code is available for the Raspberry Pi.<\/p>\n [i]<\/a>\u00a0\u00a0\u00a0\u00a0 Fechko A.
