Could you explain this a bit more - I think I don't quite know enough about electronics to follow the criticism.
Are you saying the traces are too resistive, or not resistive enough? How would that manifest - i.e. I see working circuits on the video, but are there classes of circuits that this would not work for?
- KMnO4 5y agoToo resistive. Copper, silver, and gold are used because they have very low resistance. Having high resistance in the traces makes anything more complex than a few low speed components not practical.
- zbrozek 5y agoThere's a ton of stuff I make (especially for hobby projects) where I'm pretty sure it wouldn't really matter. I'd love to fidget with stuff like this, especially since I just acquired a wide-format inkjet printer.
- wiml 5y agoToo resistive, or at least, higher than what they were aiming for. You can compensate by making traces wider to get a lower resistance from the same resistivity, or by running circuits slower (digital circuit speed is often limited by the RC time constant where C is parasitic capacitance of an input somewhere — a higher-resistance trace takes longer to charge up the input gate capacitance). How hard it is to adjust for the higher resistivity will depend on the circuit, of course.
