I had no end of trouble trying to download the SD-Card image from the Element14 website. Downloads stopping half way through, page being unavailable, etc but managed to find another smaller image that had been compiled on the forum.
You can see the original post here and the direct download from Google drive here.
Got it all installed and booted only to find my Audio board was DOA, after a quick phone call to Element14 a replacement was sent out.
Once it arrived I booted up Raspberrian and installed Shairport this time the card was detected correctly and played sound 🙂
All powered up:
This particular Raspberry Pi runs the speakers in the Kitchen and on the deck and the difference in sound quality from the onboard to the Wolfson card is significant. Will be looking at getting at least one more for the lounge.
Would certainly recommend it if you are using your Raspberry Pi for analog audio.
I recently received a firmware update for my uRAD Monitor so I thought I’d share my experience on it.
The new firmware adds a local web interface to few current stats as well as encryption back to the server.
You will need a ASP programmer that is capable of 3.3v, the firmware which you will have to request from Radu and avrdude for the flashing.
You can download avrdude from here.
I picked up a cheap ASP programmer from eBay for around ~$3 supporting both 5v and 3.3v.
Make sure the jumper is set for 3.3v.
I then pulled down my monitor and removed the two screws on the back of the unit:
Connected the programmer and powered it up, be careful as the orientation of the programmer may be different to mine!
Fired up a command prompt and avrdude to download the firmware to the flash:
Put the unit back together and reinstalled outside, after a few seconds the unit was back up and now responding with the new web interface:
Over all a pretty easy process, I look forward to future updates and am intending on building a weather station in the near future to be able to match weather data with the radiation data.
