Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...

Despite hyperintegration and systems on chips, many designs require bits of glue logic to complete or customize an interface. Similarly, many linear circuits use discrete transistors to implement or ...

MIDI is normally baked into the chipset of a synthesizer, or something you use a microcontroller to handle. But that’s not the only way to speak the language! [Kevin] decided to have some fun doing ...
