Eniro charts using SignalK & Freeboard

Image
Do you know about the SignalK workspace at Slack ? It's a really nice space where you could meet the developers and also get support. If you don't are active there you can get an invite filling in your e-mail adress at http://slack-invite.signalk.org I'm following the dialog on Slack and for some weeks ago I stumbled over a post from @chris saying that you could get, with internet connection, the online charts from Eniro displayed in Freeboard. As you see in the picture it's just for the Nordic countries. Another post installing offline charts .

Raspberry and external storage/disk

Image
There is a post, l ink will follow below, from the Raspberry Org site  which  is very informativ and handles how to connect your external hard disk, SSD, or USB stick to any of the USB ports on the Raspberry Pi(RPi), and  " mount "  the file system to access the data stored on it.   So there is no need for a rewrite and this post will therefore continue with how to connect to a Windows server , (Other SMB or Samba servers will also work), both temporary and  automagically  at boot.  Check this post RPi booting from an USB drive !

Kamado gasket glue

Image
The gasket on our Kamado Joe was falling off after a very hot pizza cooking project. After some Googling, search link here , I found several post where people, to my surprise, used 3M™ Super 77™ Multipurpose Spray Adhesive.

SignalK, measuring temperature II

Image
An introduction to the SignalK(SK), Marine application, is given  here . A very easy way to measure temperatures with SK is to use one wire (1W)  DS18B20  (DS)temperature sensors.  In a former post the DS:s where connected direkt to the RPi GPIO:s, but in this post they are WiFi enabled via the Shelly 1 (S1). Alarms are also sent when the temperature exceeds a set value. If humidity is of interest You can use a   DHT22  sensor instead of a DS sensor.
