The parts of electronics nobody writes down.

For sixteen years, two engineers and their guests have said the quiet part out loud on The Amp Hour — the rules of thumb, the failure modes, the numbers that never reach a datasheet. 719 episodes, distilled into articles where every claim is cited.

The kind of thing you'll find

Not summaries. The specific, transferable stuff.

On the Steam Controller, Valve version-locked Altium 12 for the whole project — every engineer on the same build, because a mid-project CAD upgrade is a risk you don't take.

The 12-bit ADC inside a Bluetooth SoC measured three effective bits — adequate only for confirming whether a load is on.
ep 218
A $3,000, 24-hour PCB layout service exists — with explicit limits: under 3 A, under 500 MHz, under 20 W.
