Hackaday Prize Entry: BeagleLogic

A few years ago, [Kumar] created the BeagleLogic, a 14-channel, 100 MSPS logic analyzer for the BeagleBone as an entry for the Hackaday Prize. This is a fantastic tool that takes advantage of the PRUs in the BeagleBone to give anyone with a BeagleBone a very capable logic analyzer for not much cash. This year,…

Hackaday Prize Entry: Health-Monitoring Flexible Smartwatch

[Nick Ames]’s Flexible Smartwatch project aims to create an Open Source smartwatch made out of a flexible, capacitive e-ink touchscreen that uses the whole surface of the band. This wraparound smartwatch displays information from the on-board pulse and blood oximetry sensor as well as the accelerometer and magnetometer, giving you a clear idea of how stressed…

1Bitsy 1UP

1Bitsy 1UP is a retro inspired handheld game console, the design is based on the 1Bitsy STM32F415RGT6 ARM Cortex-M4F 168MHz 192kb RAM and 1MB Flash micro controller. 2.8″ TFT with capacitive touch, SDCard Reader and a few other components.

The display used is a TFT LCD with I2C CapTouch and ILI9341 driver. (should be compatible with the display sold by Adafruit on their breakouts as well as the buydisplay.com 2.8″ tft with CapTouch sensor)

The most basic design consists of:

  • 1Bitsy STM32F415RGT6 (168MHz, 192kb RAM, 1MB Flash)
  • 240×320 2.8″ TFT with capacitive touch and PWM backlight control
  • D-Pad, ABXY, Start, Select buttons
  • DAC audio out to headphones. (speakers optional)
  • SDCard connected over SDIO interface

The hardware design files and firmware source code are available on GitHub:
