Pi Cluster reloaded
For months it has been quiet on this front, recently I have started again my efforts to have a working cluster of Raspberry PIs. I purchased a few Pi 3 (Cyberport offered them for 29,95 Euro a piece), a Logitech 8-port hub (from Pollin, around 10 Euro) that works with 5V and therefore should work by USB power. Right now I built the stack of PIs (4 Pi 2, 4 Pi 3) by connecting all of them using M2.5 nylon spacers from Banggood. As power supply I am using an Aukey PA-T8 USB charger with 10 3.0 USB ports that deliver 70W in total.
