Re: Analogue audio testing

The main audio volume. Or the volume in the player. Wherever, where it makes the samples not to be in the full range. If the sample value is for example 32760, the noise shaper tries to send something like 63-64-63-64... and 64 is out of range. Then you can hear distortions. Thanks. I was just chec...

Re: Pi 3 first impressions

Poor performance. I been a Pi 2 user. IT was slow both in LXDE and web browsing. Pi 3 improved things a bit, it feels snappier in Raspbian but web browsing still feels laggy on Raspberry Pi. I tested it on highly overclocked Pi 3. 1300Mhz cpu, 500Mhz core_freq, 600mhz ram, 100mhz sd card overclock....

Re: How are you storing & organizing your microSD cards?

One decent card left in each Pi permanently with regular rpi-clone backups stored on a totally separate machine and an external hard drive to avoid disaster. I'm 'old school'. A backup isn't a backup unless it's backed up. ;)

Re: Rasberry pi to Line-in on stereo

If it's too hissy and distorted for your ears to stand, there is a new experimental audio driver in development. It's still a little buggy at times, but overall sound quality is a vast improvement over the old driver. :)

Re: Program to Output Image to RCA Port at Certain Frame Rat

So the "certain frame rate" part just means normal PAL or NTSC output? That's what the Pi does. There's a very sensible historical reason for the PAL and NTSC frame rate of all domestic devices being fixed within very tight constraints. Back in the days when oscillators based around tuned circuits ...

Re: White, black and blurry RCA display

It needs to be proper 75 Ohm RF coaxial cable or the bandwidth simply isn't there once you get over a metre or so in length. 75 ohm RF coax cable (as used with FM and TV aerials) is a different beast from 75 ohm baseband video cable. Agreed. I never mentioned radio or TV coax though, just decent 75...

Re: RPi 1, RPi 2, RPi 3 vs. OPi 1

Basing a benchmark comparison between any two or more similar things based on the result of one test is totally nuts. A Pi is infinitely faster at running native ARM code than a top of the range Intel i7, therefore, the Pi is infinitely superior to any i7. Hoorah! :D

Re: how to measure speed of the servo

Others have also tapped in to the potentiometer that is inside the servo to get basic feedback about it's current position. This will involve taking your servo apart and soldering some wires, you'll also need an ADC so that your Pi can read this voltage. Assuming that we're talking about radio-cont...
