Our electronics workshop is equipped with three 2-person work benches. A wide selection of tools and electronics supplies and test equipment is available for prototyping.
Printed Circuit Board Design
We use Autodesk EAGLE CAD software for designing printed circuit boards. The circuit board shown here is our prototype generic electronic controller for an oxygen concentrator.
CNC Printed Circuit Board Engraving Machine
Using our small CNC engraving machine we are able to produce circuit boards for prototyping, and small scale production. The circuit board shown here is our prototype generic electronic controller for an oxygen concentrator. Using this technique we are only able to make single-sided boards. However this is adequate for basic proof of concept. Once the circuit is proven we order from JLCPCB in China (https://jlcpcb.com/). They are capable of one-day production, which starts immediately after the design files have been uploaded to their website. Shipping to Malawi is through DHL Courier.
We use Autodesk Fusion 360 for mechanical design. From these designs that are able to create tool paths to control our CNC routers, plasma cutter and 3D printer.
We have two CNC routers able to cut plastic, wood and aluminum. We use this to manufacture prototypes and for small-scale manufacturing.
CNC Plasma Cutter
While we work extensively in plastic (PVC) there are times when steel is required. Our CNC plasma cutter is capable of cutting sheet steel up to a thickness of 13mm. With our current machine we are only able to work with pieces up to 400mm square. However we plan to build a larger version in the near future. We are currently in the process of adding torch height control to improve the performance of the machine.
We have a 3D Printer able to print 3D components that are complex to cut on CNC routers.
Steel and Aluminum Welding
We have both electric arc stick welding as we as MIG wire feed equipment.
