Pulling Display Data off of a Fitness Tracker

[Aaron Christophel] writes in with yet another clever hack for his D6 Fitness Tracker. Using OpenOCD and Pygame, he shows how you can pull data right off the tracker’s screen and sent it to the computer.

This one appealed to us for its brevity. First [Aaron] launches the OpenOCD server which connects to the D6. Then, a short Python script connects to the server through telnet, reads the screen data, and uses a look-up table to turn the data into a duplicate display on the PC screen. If you’re more of a visual learner, there’s a demonstration video after the break.

The D6 is a popular fitness tracker that’s often re-branded and sold at a very low cost. [Aaron] is a big fan of these Nordic nRF52 powered devices, and we’ve covered some of his hacks before. If you’d like to learn more about these interesting little devices there’s quite a write-up on their inner-workings here.

A Mini USB Keyboard That Isn’t A Keyboard

A useful add-on for any computer is a plug-in macro keyboard, a little peripheral that adds those extra useful buttons to automate tasks. [ Sayantan Pal] has made one, a handy board with nine programmable keys and a USB connector, but the surprise is that at its heart lies only the ubiquitous ATmega328 that you might find in an Arduino Uno. This isn’t a USB HID keyboard, instead it uses a USB-to-serial chip and appears to the host computer as a serial device. The keys themselves are simple momentary action switches, perhaps a deluxe version could use key switches from the likes of Cherry or similar. The clever part of this build comes on the host computer, which runs some Python code using the PyAutoGui library. This allows control of the keyboard and mouse, and provides an “in” for the script to link serial and input devices. Full configurability is assured through the Python code, and while that might preclude a non-technical user from gaining its full benefit it’s fair to say that ...
