The Raspberry Pi Thread [5]

A may get this one, it would be something I might add to an order. Boldport Buggy – Pimoroni Store My grand daughter would have fun with it. Until the battery died anyway, lol. I don't see an on off switch.

One of my Wife's friends sent her one of those little talking cloth pillow thingy's. Looks like a pin cushion. You press it in a certain spot and it plays the message they recorded on it. Once I figured out how to rerecord the message my grand daughter Ivy had a ball recording her own messages on it and giving it to others to play them back. If you hold the play button down for 2 seconds it beeps, you talk, let go of the button, and it beeps again. Message recorded. Press that same button just once and it plays the message. I'll open it up and have a look inside once the battery dies. I'll do it so my wife can sew it back up again. Assuming I can replace the battery.

I have the guts from one of those music playing greeting cards around here somewhere. They just played music though, and I don't think you could record your own message. I nver figured out how to change it. I always saved the battery, and the speaker. They aren't super quality but usable for playing around with anyway. I'd imagine this pilow has similar stuff inside, but with extras. A microphone and maybe a better speaker.

Completly redid my LED Shim Pressure display code. It just wasn't working correctly.

Code:

def ledpress():
    if sensor.get_sensor_data(): 
       p = sensor.data.pressure 
       p = round(p)
    set_multiple_pixels(range(0,5), 255, 0, 0)         # Red    - Very High
    set_multiple_pixels(range(5,11), 0, 0, 255)        # Blue   - High
    set_multiple_pixels(range(11,17), 0, 255, 0)       # Green  - Mid Range
    set_multiple_pixels(range(17,23), 255, 255, 0)     # Yellow - Low
    set_multiple_pixels(range(23,28), 255, 0, 0)       # Red    - Verry Low
    if p > 1070:
       M == 0
    elif p >= 1048 and p < 1070: # Very High  M is 0 - 4
       N = (p - 1048) / 4.1  
       N = round(N)
       M = 4 - N
    elif p >= 1026 and p < 1048: # High       M is 5 - 10
       N = (p - 1026) / 3.6 
       N = round(N)
       M = 10 - N
    elif p >= 1004 and p < 1026: # Mid Range  M is 11 - 16
       N = (p - 1004) / 3.6 
       N = round(N)
       M = 16 - N
    elif p >= 982 and p < 1004:  # Low        M is 17 - 22
       N = (p - 982) / 3.6 
       N = round(N)
       M = 22 - N
    elif p >= 960 and p < 982:   # Very Low   M 23 - 27
       N = (p - 960) / 4.1
       N = round(N)
       M = 27 - N
    elif P > 960: 
       M == 27 
    ledshim.set_pixel(M, 0, 0, 0)    
    ledshim.show()     

I've got a couple of Pi / Raspbain tweaks I found.

From a terminal window run
sudo nano /boot/config.txt
and add
disable_splash=1
to it.
This will kill the big rainbow square you see on screen on bootup.

From a terminal window run
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart
and remove the @Point-rpi
line.
This should put your cursor in the center of the screen on boot up instead of on the taskbar menu.

If your wanting to know what your CPU temps are, especially if its a Pi 4B

from terminal run
cat /sys/class/thermal/thermal_zone0/temp


Or add the "CPU Temperature" panel applet to the task bar on the Raspbian desktop. << What I did.

I have my Pi4 setup using a pimoroni 4 letter Phat to show the temps in real time ,starts off in the 30's and has gone as high as 80, got to the 80 when running some youtube video's but usually around mid 50's to 60 -65 basic surfing on the Web

I'm likely going to setup a Blinkt or LED Shim for my Pi 4 temps. Just something graphical at first. At some point anyway. I don't currently have a Blinkt or a spare LED Shim. Plus I'm not using my 4B for any dedicated use yet. I've only just been tinkering with it a bit so far.

EDIT: forgot to mention, thats a nice way to make use of your 4 letter. Well I guess its now a two number pHat.
