We blogged about this cool project that converts a PC joystick to USB https://github.com/necroware/gameport-adapter and we realized there's probably millions of these old joysticks folks may be wanting to update or interface with. So we threw together a quick PC Joystick QT breakout! I'm using seesaw cause we need analog inputs as well as digital and once you have ADC + GPIO in an I2C project we feel we're best off going with a microcontroller. We also wrapped up an ancient PCF8574 https://www.digikey.com/short/7bvpbqvt QT breakout and wrote a library for it. The PCF8574 is a very wierd little chip which does 'bidirectional gpio expansion' but without a direction port, how's it do that? Tune in to find out! :) The Great Search - DE-15 PC Game Port connector with Screwlock Standoffs https://www.digikey.com/short/v5pzcqfz On this week's Great Search we're on the hunt for a super-retro component: a connector that will match up with PC Game port connectors like you had on your old 486dx with a Sound-Blaster 16. We're looking for something through-hole, right-angle, with 2 rows of sockets. We also want the lil 4-40 hex standoffs that are used to secure the joystick to the connector. Let's see whether we can find it in stock on Digi-Key!
