Ah that looks decent, good brand as well.

I think its just my cheap sound card, the recordings just seem to have less definition and frequency range compared to the original recording.

However turning down the gain in ALSA has helped a bit.

Hi all, I'm trying to use my Pi to record audio input at the best possible quality. I bought one of these: http://www.amazon.co.uk/gp/product/B00IRVQ0F8?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 and am using ALSA (arecord) to record the audio. This all works, but the sound quality isn't gr...

Hi, I've built a small robot that is being driven by my pi and controlled with an android app for my uni project. I'd like to add a turret gun type thing that could be triggered via gpio ports. I've seen people doing it with nerf guns, but I'm after something a bit more turret like (rather than hand...

Hi, I have a program driving an adafruit lcd plate (with an mcp23017) using the wiringPi library that runs as a daemon on boot. This is all great, but after about 2 days (always roughly the same amount of time) the lcd will stop updating and the buttons become unresponsive. Restarting the program wi...

Managed to get it working by using a forked process to poll the keys every 50ms and send a signal and pipe the key code back to the main thread when a button is pressed.

Hi, So I've got an LCD plate that is being driven a project I'm writing in C on my raspberry pi, and I've got it displaying some useful info on the screen (pic if anyone's interested: https://dl.dropboxusercontent.com/u/41066217/IMG_20140509_091720~2.jpg). I'd like to have the LED backlight only tur...

Thanks for the great replies, these were very helpful.

Hi all, I'm hoping to create a motorised vehicle controlled by the raspberry pi's gpio ports for a uni project. However, my focus is going to be on the software, and I'm not particularly knowledgeable in electronics. Just to make sure I have the right idea before I invest in this equipment, if anyon...
