The Great Search: 1N4148 Signal Diodes in DO-35 and SOD-1...

What this episode covers

Looking at a lot of keyboard kits, we noticed that many use a diode key-matrix to connect lots of keys without a ghosting effect. We should probably source long tape strips of 1N4148s for folks making keyboards and key matrices! Let's talk about 1N4148s in two packages - DO-35 (classic glass) and SOD-123 as seen on a keyboard we purchased.
