Whereas the title “SAO” may generate a lot of heated dialogue about what it ought to stand for (Easy Add On, SuperCon Add On, or its earlier extra unmentionable title) the premise of what they’re is easy. These little SAO doohickeys are small circuits that may be added on to SAO-compatible badges, with many hacker/geek/maker conferences badges being SAO compliant, that includes the usual SAO 6-pin header on board. These revamped Rocket SAO are a good looking instance of a wonderful badge adornment utilizing subtle reverse mount NeoPixel addressable RGB LEDs to mild and animate components of the design.
The lovingly crafted PCBs are actually out there in purple, blue or purple solder masks and every one options 3 NeoPixel mounted on the reverse. Other than the SAO 6-pin connector, there’s an ATtiny 412 microcontroller on board with one of many 6-pin connectors used as a UPDI pin to make it simple to program. Should you haven’t used the marginally newer ATtiny412 earlier than there are many glorious tutorials on-line and it’s similar to utilizing the older ATtiny85 variants, plus they’re appropriate with the Arduino IDE.
Whereas we are able to admire how good these would look hooked up to a pleasant convention badge SAO connector, we love that these even have fittings to connect to a small lanyard or key ring and we predict they might look pretty related as a collection of rockets in flight!
