Code for counter "display", "cone" lights and "heartmonitor" components of Ogutu Muraya's show 2018.08 ... in progress

Notes on display after years

The repo doesnt have all information

• https://github.com/cyphunk/because_i_always_feel_like_running

• Wifi: export CLIENT_SSID="MtElgon" export CLIENT_PASSWORD="oguturunning" IP given by router

Orientation

• Startup routines

  • crotating square, cross pattern, pacman, row,col, glow, text, counter

  • Row,column: On start you will see row,column descriptions show in bottom left. Example with default configuration.sh:

    panels when viwed from front [ 0,0] [ 0,1] [ 0,2] [ 0,3] [ 0,4] [ 0,5] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] <-- [ rpi ]

    panels when viewed from back [ 0,0] [ 0,1] [ 0,2] [ 0,3] [ 0,4] [ 0,5] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ rpi ] --> [ ] [ ] [ ] [ ] [ ] [ ]

    cables when viewed from back: i : in port o : out port ^ : ⮠ symbol v : ⮦ symbol * : power .-----------. .-----------. . -----------.
    v v v v v v
    [o ] [ i] [o ] [ i] [o ] [ i] [ ^] [ ] [ ] [ ] [ ] [ ] [ * ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [ ] [^ ] [ ] [ ] [ ] [ ] [ ] [ rpi ] --> [i ] [ o] [i ] [ o] [i ] [ ] ^ ^ ^ ^ '---' '---'

configuration.sh

• Panel 6 first to pi (pi therefor on right,bottom when viewed from front (default) MATRIXARGS=--led-rows 32 --led-cols 64 --led-pixel-mapper="S-Mapper;Rotate:90" --led-chain=6
• Panel 0 first to pi (pi therefor on left, top?)

Power (assume 0.30EU per kWh):

measured with the In Btertekeware WBP 302737 power meter

• 08w still text on: 0.18kWh/day €0.06 - 1.3/w €0.4 - 05.8/m €1.75 - 070/y €21.04
• 10w pacmananimate: 0.24kWh/day €0.07 - 1.7/w €0.5 - 07.3/m €2.19 - 088/y €26.30 (or even the cross grid image)

Jitter on brightness. RPi2 with image 2017-09-07-raspbian-stretch-lite.zip has significantly less jitter than RPi3 with image 2018-06-27-raspbian-stretch-lite.zip. This is even after isolating user apps to 3 cores, disabling bluetooth, etc.

The fake Heart to OSC emulator works for demo purposes but could use improvements. I was working on trying to change it so that higher HR produces a higher range of amplitude on the brightness. Also at the moment the HR brightness modulation only works in the counter.

HDMI or VGA input. We tried USB configurations which kinda work with only slightly reduced quality (samples instagram) but causes entire system to crash often after 5 minutes of use. Started working on integrating the avid hdmi to camera port attachment but currently wasn't getting any valid image.

In the future would like to see resolutions for

• brightness modulation with 100% brightness.
• setup bluetooth HR
• hdmi input
• fadein/out media
