  • I started with an RPi 1b to read out my weatherstation (WH1080 clone) and post it online with weewx. Then a Bananapi R1 entered to replace my intel system as firewall/core router (savings on power usage, a lot). The RP 1 got replaced by a RPi 2, and tne 1 moved to the smartmeeter for readout. The main server (huge AMD tower) got replaced by a RPi 3 (again, power savings), Bpi R2 replaced the R1 when bananian development stopped. RPi 3 died on me (sd slot failed) and I got a replacement. As the 1st RPi3 was dead anyway, I tried to repair it (only use of the solderings at the side proved to be to keep the slot in place) and used it to replace the Bpi R2 as support got problematic.

    The main server got upgraded to a RPi 4 8GB, with the RPi2 replacing the RPi2 that was handeling my weatherstation. I got an rflink, so I added domoticz and that now powers my kaku (dutch power switching system) in a mixed old/new setup. The RPi3 that was my main router (internet router via fiber) got replaced hh an RPi4 witn 4 GB mem, as the 2 GB mem version wasn’t available. (Not a bad move, with the on-board non-usb 1GB interface and a tad over 2 GB mem use)

    The freed RPi3 is now for the smartmeter, so all RPi are 64 bit. (All running aarm64 Debian) Both Bpi’s and RPi 1 and 2 are collecting dust, as I haven’t found a use for them… yet. Looking for projects to use them. As media server they’re to light. (Although, Bpi R2 could be useful for that)



  • Depends, define free and define useful. ;)

    You can learn a lot by reading up and watching YT vids. I already did my own car maintenance (started as hobby, now it’s a necessity, car mechanics cost twice/trice my hourly wage), but didn’t know how to replace the fuelpump on this modern car. Garage quoted €500, part was 109, special tool 79, seals 5 each (2). Replaced it myself in 4h.

    I’m also learning to play bass guitar with the help of YT (already have the bass), painted my house, replaced kitchen and parts in bathroom including plumbing,… None of DIY things for free, but cheaper then hiring somebody to do these task. Even when you count your hourly wage, most of those tasks can be done cheaper yourself.

    When you want no investment at all, languages are very useful to learn, at least when you meet others speaking those languages. Learning to setup a computer with free software is usefull as well (saves cash, so eeven better then free ;) ).

    At this moment in time, in most pasrts of Europe and the USA, labour is the most expensive part of everything, so I’d say everything you can learn to do yourself is worth investing some time and maybe some cash in. Nothing wrong with hobbies that can save cash in the long run.
