Weekend Project. Fan controll for the new Raspberry PI 4. No programming just bash and cron. Based on https://hackernoon.com/raspberry-pi-temperature-controlled-fan-2aa0de72a564 with change for on/off tresholds.

#!/bin/sh timestamp() { date +"%Y-%m-%d %T" } LOGDIR="/var/log/fan.log" VALUE_ON=55 VALUE_OFF=50 TEMP=`vcgencmd measure_temp | cut -c6,7` STATUS=`cat /sys/class/gpio/gpio2/value` echo `timestamp` " Info: Temperature: $TEMP">>$LOGDIR if [ $TEMP -ge $VALUE_ON ] && [ $STATUS -eq 0 ] then echo `timestamp` " Warning: Fan started.">>$LOGDIR echo "1">/sys/class/gpio/gpio2/value elif [ $TEMP -le $VALUE_OFF ] && [ $STATUS -eq 1 ] then echo `timestamp` " Warning: Fan stopped.">>$LOGDIR echo "0">/sys/class/gpio/gpio2/value fi

Add the following add the end of /etc/rc.local to enable the GPIO port after reboot.

# Set GPIO 2 to "out" mode to enable fan control echo "2" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio2/direction

Save filled out PDF that Adobe won’t let you

Have you ever had a PDF that can be filled out in Adobe Reader, but Adobe won't let you save it and even messes with your Mac's Print to PDF function? Here is how to do it anyway. With these two commands you can snatch it form the printer queue.

sudo ls -tp /private/var/spool/cups | grep -v / | head -1 | pstopdf sudo cp $(ls -tp /private/var/spool/cups/*.pdf | head -1) ~/Downloads

Use OpenSeaMap in Basecamp

1. Download the map from here: https://wiki.openstreetmap.org/wiki/DE:OpenSeaMap_and_Garmin_nautical_chart_plotter

2. Use a USB Disk or SD-Card and create a garmin folder on it.

3. Extract the gmapsupp.img file and copy it into the garmin folder on the device

4. Open Basecamp and allow it to read the devise.

5. Switch to the new map in the Maps menu.

Haven’t figured out yet how to load it onto the harddrive.

Finaly got my FlyKly Smart Wheel working. Had to change the sprocket to 3/32" to fit with the gear chain. Kickstarter meets Startnext with the BienenBox in the background :-)

Sending E-Mail with GMail-Alias in Apple Mail

It took me while to find the right solution here as it's not obvious.

Say you own [email protected] and use that as alias in your GMail account [email protected]. It's easy to choose you bar.com address as the from address in the GMail Web Interface, but how to hell do you get this enabled in Apple Mail.

Just put in [email protected],[email protected] into the E-Mail address field of  GMail Account settings in Mail.

Next time you write a mail you'll notice a drop-down menu for the From field in the editor.

That's it.

Importing multiple GPX tracks into Endomondo

Endomondo is my single source of truth for exercise stats and I use the app for all kinds of sports. However sometimes I enjoy a run with Zombies Run! or track hikes with MotionX GPS.

So from time to time I need to import tracks from those apps into Endomondo. Unfortunately you can only upload one GPX file at a time. Luckily Endomondo supports GPX files containing multiple tracks.

In order to eliminate the tedious task of uploading tracks one by one I was looking for a way to combine them into one GPX file.

The topic has been covered in many forums, but most of the solutions where not really slick or did not work on Mac OS X.

Finally I found GPSbabel that did what I wanted in a efficient way.

Just drop all your downloaded GPX files into the input field give the export file a name in the output field and hit OK. That's it. Now you have just one file to import into Endomondo.
