Freeforming usually means taking the bare components, bending, trimming and soldering leads together.
You will require a good Toolset including:
Now - following our Safety Guide- you should also have the following:
You also need a lot of patience, and I seriously do not recommend doing this while tired.
It is also worth having a back of push in connectors. The reason for this is that you can freeform modules of circuits, and join them with jump wires. While this may add a little size and weight to a freeform, it will still be less than a PCB equivalent.
First be aware of the circuit you are using. Take each of the components, and judge the size and shape. Think about how many input/output connections the circuit needs. It is usually a good idea to have most IO connections facing the right way. Once you have all of these - then it is a matter of inspiration. For each idea, sketch it out (which is difficult because these tend to be more '3D' than PCB circuits) and trace the pathways - make sure all the correct connections are there. Try to limit risks of leads that shouldnt be touching accidentally doing so. This may mean glueing a peice of paper between them.
