[sdiy] Euro Synth Spec

[rsdio at audiobanshee.com]

Some ribbon cables are difficult to plug in offset. Others are quite easy. I happen to have nothing but ribbon cables where the plastic header will not bend neighboring pins, and thus it’s incredibly easy to plug in offset by mistake. Of course, that’s only with unboxed male headers.

When I was younger, I had all the time in the world to be super meticulous. It seemed that I never made a mistake! Now, I don’t understand why, but I seem to be the most impatient person in the world - at least from the perspective of the younger self that I remember. In any event, I have a lot of empathy for those who complain about the Euro “standard” power connector.
