Using a LED and a 560 Ω in most breadboard projects means that you end up with four pins connected for two components, soldering them up like this makes them much easer to handle.
I found the ‘Picktor’ Pick and Place head for retrofitting on a 3D printer on Thingiverse (GitHub) As designed it uses a Nema 17 stepper motor, however I suspect that will be too big for my design. I got 3 x Nema 14 stepper motors from an old RepRap Huxley, […]
