I read a report recently that confirmed that straight PCB traces, right angle, and orthogonally placed components can actually make electrons sad and slow them down. They much prefer the excitement of whizzing along curvy traces, particularly if they end up going in to a chip at a random angle. And bright colours really make them want to work harder.
So I will be updating all #RC2014 kits with design philosophy. The first to be done is the RC2014 Mini II Picasso. You can pick one up now at #z80kits
