yeah i got that email ,and got another days later asking if everything was ok with order , i replied that i never received it at that time .,..they never answered then, i had to send another email to inquire about the order days later,,all is good ,cant expect it to go 100% all the time ..

.

I've had some come really quick and some take a dogs age to arrive. Canada Post at its finest. Anyway, the links to do the reviews should be in one or both of those e-mails.

There is a Pi Day Windows theme available though the Windows store if anybody is interested. Its not a Raspberry Pi theme just a Pi (3.14) theme. I can't figure out how to link to it though, there is no URL shown in the Store App?
If you got to settings > Personalization > Themes > Get more themes from the Microsoft Store > Then in Search type Pi Day.

This was posted by Scott on the Pimoroni forum to increase the VU meter sensitivity on the pHat Beat. It works but mine is actually a bit too sensistve now. I get full scale at low to moderate volume levels. Still better than the one of two leds I was getting at that same volume. I "think" its the "131071.0f" that needs to be chnaged, but not 100% sure? I'm waiting on a reply as to what to change to tweak it to what I want as a level.

Scott
You can increase the sensitivity on the Phat Beat VU Meter by doing the following:
cd Pimoroni/pivumeter
nano src/devices/phat-beat.c
Change line 88 to:
int bar = (meter_level * (meter_level / 8) / 131071.0f) * (brightness * (NUM_PIXELS/2));
Recompile the library:
sudo make
sudo make install
Now your VU meter is more sensitive! Tweak the values to your liking.

will have to give that a try when i get home ,We are visiting family in halifax again

I made an edit, I do believe it should be sudo make, not make. I got an error just running make. I can't seem to lower the sensitivity now? I've been trying lower values in place of the

131071.0f ? It doesn't seem to make any difference? I may try a higher number.

Higher is better. Its / dividing by that number so the larger it is the lower the result of the math will be. I'd try something like 600000 or 700000.
I'd adjust your volume to the level you usually listen to it at. Then play with that number until you get the response you want on the VU meter.
You need to reboot to see the change.

I ended up at 1000000, but I have my volume a bit on the loud side. There are some fans running in that room in an attempt to cool things off a bit.

thanks for the info ,will give it a go early next week

The original edit changes that line quit a bit. I can't say as I understand what it does but it works once you tweak the numbers after the edit. You have to do the make and make install every time you edit it. I did anyway. And a reboot.
