 The ESP8266 module is capable of sending almost arbitrary WiFi packets, including so-called deauthentication packets and packets including beacon information.
 Browsing the internet, I found that RandDruid [already did](https://github.com/RandDruid/esp8266-deauth) most of the work for me. He wrote software for the ESP that kicks everyone in range out of their WiFi hotspot. Why does that work? The router and the client talk to each other. The router can send a special packet - the deauthentication packet - to the client that makes the client disconnect. The software now searches for nearby hotspots and clients, and as soon as there are any found, the module, claiming to be the router, sends the deauthentication packet.
-There is another special packet that tells a client a router's name (SSID) and a kind of address (MAC). kripthor wrote a [small example](https://github.com/kripthor/WiFiBeaconJam) that blasts a ton of random beacon packets in the air. I used their code as template for a function that I included in RandDruid's original software. You can download the code [here](https://git.schneefux.xyz/?p=jimmiejammer;a=blob;f=jimmiejammer.ino;).

 Next came the hardware part. The ESP8266 is a 3.3V device that draws up to 200mA, maybe about 100 mA on average in this application. As power supply, I used rechargable LiFePo4 batteries. Those are very robust and, unlike typical batteries, stay at 3V for a long time. Mine has a capacity of 700mAh which should be enough for a few hours.
 The battery can be directly connected to the ESP. I added a switch to be able to turn it on and off and save energy and nerves.

 The setup consists of cheap RGB LED strips, 2 \* 5 meters, powered by two 12V 3.5A adapters and an Arduino with three TO-120 transistors each.
 For strips with 30 LEDs per meter, you need 0.5A per meter. To be safe, add additional 10% to the total. So for my 10 meters, I could also have used a single adapter with at least 5.5A.
-The Arduino's GPIOs are not nearly able to supply 5.5A \* 12V = 66W, so we need transistors - either darlington transistors or MOSFETs. [Adafruit](https://learn.adafruit.com/rgb-led-strips/usage) has more information and detailed explanations. After wiring, the Arduino needs to be flashed with a software that communicates with the Raspberry Pi. I adapted a sketch that implements the Adalight protocol, you can find it [here](https://git.schneefux.xyz/?p=mpd-rgb-vis;a=blob;f=adastrip.ino;hb=HEAD).

-The Raspberry Pi as server runs [Hyperion](https://github.com/tvdzwan/hyperion) which is AmbiLight-like. On the same host, MPD outputs music to speakers and a FIFO. I wrote a Hyperion plugin that processes the output of the FIFO and thus visualizes the music that is currently be played. The plugin and more installation instructions are [here](https://git.schneefux.xyz/?p=mpd-rgb-vis;a=blob;f=README.md;hb=HEAD). In my case, I started two Hyperion daemons, because I had two Arduinos connected and it is currently not possible to output the same data to two Hyperion compatible devices.

 Initially, I planned using an ESP8266 instead of the Arduino. I had not the right parts to step down 12V to 3.3V and tried to hack something together with LEDs and a 7V-3.3V-stepdown converter.
 Well… that didn't work out quite well. I used Arduino Unos instead.
