This section documents the possible sensor configurations you can build for yourself, and also provides instructions what you need to purchase and how you are able to build your own OBS.

Starting out, make sure to check out the model selection to figure out which version of the OBS you want to build.

If you plan to build multiple OBS it is recommended to first print and fully assemble one version. In the past sometimes suppliers have slightly changed dimensions of parts they deliver. If you notice that before you print a bunch of cases it can still be fixed in the model. In that case mention it in the [Community](/en/community/. This allows us to adapt supplier lists or the case as needed.

Next up, you will need to figure out all the parts that you need to purchase or create for your selected model. This includes a lot of electronic components, a PCB, the 3D printed case and fixtures, wires and fasteners. Check out the detailed BOM for your version.

We also provide instructions here on printing your own cases, ordering PCBs from your favorite manufacturer, and for assembly of the sensor from all the parts.

Note: This website is still work-in-progress, and some parts of the documentation are not complete. If you run into trouble, ask in the Community. Don’t expect a smooth experience just yet – but we’re working on it. However, don’t fear, while not necessarily straightforward at all times, it is still very much possible for beginners to complete this build and construct their own OBS.

Construction kits

Because the OpenBikeSensor consists many parts from many different sources, bulk orders organized by local groups are advisable. Head over to Community if you want to organize or paricipate in a bulk order.

Getting a PCB

You will need a PCB (printed circuit board) to solder all components to. Here’s how to get one.
