Yes. The written Armstrong build guide is on our Resources page. Armstrong is no longer sold, but the guide stays published, so you can still build one or repair one you already own.
The guide covers:
Photos and diagrams for each assembly step
Component identification, so you can match a part in the box to a part in the guide
Soldering guidance for this kit
Checks you can run as you go, to confirm each stage works before you move on
Some kits also have a video walkthrough on the CircuitMess YouTube channel, but the written guide is the reference to follow for Armstrong.
If you cannot find the guide, or a step is unclear, message us here, or email [email protected], with the step number and a photo of your build, and we will talk you through it.
