Re:Show HN: Raspberry Pi3 cluster with Docker/Kubernetes

Translation for those who care:
-------------------
This time round I got into carpentry for my project. Something that became both expensive and trickier than I had thought when I started. My carpentry knowledge is limited to (high-)school lessons, so take it easy on the results.
The project became more expensive than expected. Some 6000 SEK [~$740] including a whole bunch of tools (mill, jig saw, circular saw). Made do with 'Biltema' tools [the IKEA of tools] and returned the first mill after 1 hour of use. The other stopped after around 2 hours so then I fixed that one myself (took apart the start-button and modified it a bit).
The project consists of:
- 10/100 Mbps switch
- Nexus 7
- 10A 6 port USB charger
- 4 x Raspberry pi 3
- 4 x 8GB SD card
- TP cables + USB cables
- Oak
- Plexiglass
Anyway, you'd all probably rather see pictures than words.
- Nexus 7 with realtime data for all nodes.
- 'Economically' bought 8GB, not class 10, but thinking of running a 2.5" HDD for the controller node.
- Sleeved all the cables, then realised that they didn't fit with the sleeving. Could only strip them and do again.
- First test with 2 x USB hubs that didn't deliver enough current at start-up.
- Flip-up "chassis"
- My modified netdata page showing real-time data for all nodes, including the temperature.
