-====== Scottish Consulate Badge ======
+====== Consular Badge ======
-====Concept====
+An electronic badge for Scottish Consulate  members and visitors. Uses an Arm Cortex M4 STM32F303K8 and Nokia LCD. The integrated multimeter measures 0-30 Volts and 0-1 Amps DC, resistance to 10 MegOhms and provides audible continuity measurement. The Pusheenicorn has 6 neopixel multicolour LEDs on her mane and tail. Shitty Addon V1.69bis connector and NRF24L01 wireless connectors are also provided.
-An electronic badge for ScotCon members and visitors. Low cost, straightforward self-assembly, unicorn or pusheenicorn shape, LCD, neopixels, multimeter, IO ports

-====PCB====
+Front
-Max 100x100m 2 layer 1.6mm FR4 material, 1oz copper, 0.3mm min hole, 0.4mm solder mask dam, 0.42mm min track, HASL finish, blue finish/white silkscreen for minimum manufacturing cost from Seeed Studio
-Form factor: Unicorn, Pusheenicorn or Saltire, must be easy to mill, no complex shapes/sharp corners to minimise cost

-====Processor====
+{{:wiki:badge_under_test_scaled_img_20190615_143015.jpg?400|}}
-ARM Cortex M4 STM32F303K8 Nucleo board (64K Flash), development environment ARM MDK V5 (free version, 32K code limit), OpenSTM 32 also possible, no code size limit but less stable
-====User Interface====
+Badge Prototype Under Development
-Nokia 5110 LCD, 500uA @3V 6mA @5V (can reduce backlight LED current via resistor)
-Neopixels on tail/mane
-Buttons and/or joystick/rotary encoder
-====Multimeter====
--50V DC/AC, continuity, diode test
-====Communication====
-UART/serial port - serial terminal or packet radio monitor connected to TNC?
-Shitty Add-On (I2C) connector
-Wireless - NRF42L01 module (cheap clones on eBay) - interact with other badges; 433 MHz packet radio receiver - pager receiver or LED control?
-====Power====
-V battery: LiPo, 2xAA or coil cell? Or 1x AA and boost converter? USB charging?
