summary
Builds a programmable friendship bracelet called Jewelbots that runs C++ firmware, uses the nRF51822 BLE chip and is coded via the Arduino IDE, shipped from Kickstarter to retail with almost 10,000 units in 25 countries. Describes injection‑molded shells, micro USB uploads, a tiny 4×4 mm MCU, and a simplified C++ API for LEDs, buzzers, timers and friend‑group events. Reports a 44% conversion rate from play to coding, lists workshops and open source schematics, and shows the device working live.
