Webradio with Wemos

thingiverse

I wanted to build an internet radio for a long time, but all the devices were too expensive. So I started looking for a DIY web radio and stumbled upon Edzelf's [Webradio](https://github.com/Edzelf/Esp-radio). What caught my eye was that it's based on ESP8266. Since most of my smart home sensors are realized with Wemos D1 mini, I still had some at home. The description by Edzelf is well done. However, I was looking for alternatives and stumbled upon Michael Dworkin's [article](http://esp8266-server.de/Internetradio.html). He uses PAM8403 as an amplifier and has many additional tips. With that, my shopping list was clear, and I ordered the MP3 modules VS1003/VS1053 and the amplifier PAM8403 from Adafruit. Besonderheiten: • At the potentiometer of the amplifier PAM8403 is a small nose, which must be filed down. • As can be seen on the pictures, you need a drill grid for the buttons. On the pictures and the Fritzing plan, the wiring should be clearly visible. The logic and also the "adjustment" is well described in Edzelf's PDF under „Analog input“ page 5. • Diode at Wemos D1 mini bridge/ remove. Between the USB mini plug and the 5V pin on Wemos D1 mini is a protective diode built-in. This breaks when there's a current for MP3 module, TFT and amplifier, causing noise and maybe resetting the Wemos D1 mini. I simply bridged the diode with a piece of wire. You can also remove the diode and bridge the Lötpads. I explicitly point out that you disable one safety feature of the Wemos with this modification and put yourself at risk. If you're not aware of what you do, build your own power supply. I take no responsibility for your modification.
