Richard Hayler likes to keep fit but his recent job change has meant that he unable to get to fitness sessions with an instructor. He now exercises in his back garden but wanted some way of having a visible and audible cue to his programme of exercises. Enter the Raspberry Pi. Richard’s taken a Raspberry Pi Zero, Pimoroni Scroll pHAT HD, a Pico HAT Hacker, a couple of buttons and a buzzer to make his own Pi-rsonal Trainer. The exercises are programmed in and the buzzer sounds when he needs to move onto the next one. The Scroll pHAT is used to display the current exercise and the whole thing is portable thanks to USB battery pack. Read more about the build here and see a video of it in action below:
