+### Examples of bits and pieces running at Jessie level 
+
+These shell-scripts are located on my EV3-brick at `/usr/local/bin`
+but with some simple edits you can place them where **you** want them.
+
+ 1. Supporting script(s) used by other scripts
+    * [asciicolor](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/asciicolors)
+
+ 2. Scripts related to managing the EV3-brick
+    * [checkpower](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/checkpower) 
+    Add this script to a crontab to check for the battery voltage. On lower power the EV3-led on the left will blink green on lower voltage, then amber and eventually red (with one beep).
+    * [showactivity](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/showactivity) Makes the right green led blink on I/O activity.
+    * [stopmotors](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/stopmotors) Well, stops all motors.
+
+ 3. Scripts discovering sensors and / or motors
+    * [blinkleds](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/blinkleds)
+    * [setled](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/setled)
+    * [showleds](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/showleds)
+    * [showmotor](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/showmotor)
+    * [showpower](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/showpower)
+    * [showsensors](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/showsensors)
+    * [showsound](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/showsound)
+    * [testmotor](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/testmotor)
+
+### Have your EV3 report it's IP-address by speach after boot
+For this an update is needed to 
+[`/media/mmc_p1/ev3dev.rc.local`](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/rc.local)
+
+Add the next lines to the bottom of `/media/mmc_p1/ev3dev.rc.local`
+
+```if [ -e /media/mmc_p1/tellIP ]; then    ```
+
+```echo "Executing /media/mmc_p1/tellIP"   ```
+
+```source /media/mmc_p1/tellIP             ```
+
+```fi                                      ```
+
+
+and an extra script [`tellIP`](https://github.com/BertLindeman/bert-ev3dev-examples/blob/master/tellIP)
+in the same directory: `/media/mmc_p1/`
