via Google I found this forum, so maybe I can find some experts here for the problems I encountered while planning a new project: an internet radio via Raspberry Pi and a compartible touchscreen. Since my kitchen radio broke some days ago and I still have a Raspberry Pi around, that might be a good use for it along with a small touch screen. Some questions that came up:
Is it possible to automatically start Volumino (or a similar software) after booting a RasPi, perhaps with a script of some sort like using the Autostart on Windows? If yes, how so?
How to best manage the audio. Here I thought about using a small BT speaker. Is it possible to use these with a cable 24/7? Sound does not have to be that great, just at least better than the tiny little small speakers in my old radio.
Now the hard part: Is it somehow possible to solder any kind of manual switch to a RasPi to get it to shutdown fast/automatically? Since I need to get up at 5am each morning while having only very limited time, I just lack the time and I dont feel like shutting it down manually each time.
I think especially #3 will be the hardest part. Anyone tried similar projects before? Thank you in advance.
I think I have something that can be a good solution for you.
I made a HAT for Raspberry Pi, optimized for using it with Volumio. It is powered by one of the latest amplifiers from TI, stereo output with 30W per channel.
The difference with other similar HAT in the market is a physical ON/OFF switch, to turn fully OFF both Raspberry Pi and amplifiers. The GPIOs that are not used are exposed on a 2.54mm connector, you can connect LEDs or push-buttons for safe shutdown of the Raspberry Pi.
You can connect a display with touchscreen if you want, both cheap and expensive ones.
Here with 3.5" touchscreen
Nice. Where can we find it?
it’s not available yet. I got the first batch of PCBs some days ago, for testing purpose. No issues have been found, I’m waiting for the quote of the 2nd batch.
At the moment I am initializing the amplifier with a python script, it’s working fine but no Hardware mixer is available. I already contacted someone for a proper Linux driver.
If you are interested in the product, please contact me in private, I can provide you one at production price.
I’m interested in a test sample
Send me a PM
I just sent the order to the PCB manufacturer, I should get the second small batch within 3 weeks
