Practical technology guides: Android, Windows, self-hosting, smart home, EVs and more — tested, step-by-step, no fluff.
How many players can a Pi really hold? Realistic PaperMC ceilings for Pi 4 vs Pi 5, the Bedrock ARM problem, the tuning levers, and a Docker setup.
An honest per-console, per-Pi playability matrix: which systems run full speed on Pi 3/4/5, which are marginal, and which distro to actually flash.
Android backup isn't one system, it's three, and none of them cover authenticator app seeds. Here is what Google One, Google Photos, and WhatsApp actually save, what gets skipped, and how to migrate phones without losing your 2FA codes.
The hub guide for home EV charging in Germany: the total cost picture (€1,200–3,500 upfront, ~€5.50–7.40/100km running), a six-decision framework (own vs rent, wallbox, electrician, process, running cost, optional solar), and routes to every detailed spoke.
A sourced 2026 comparison of Germany's major public EV-charging networks — EnBW, Ionity, Aral pulse, Tesla Supercharger, Allego, EWE Go, Shell Recharge — covering ad-hoc vs app/subscription pricing, AC/DC surcharges, blocking fees, and how public charging stacks up against charging at home.
Charging your EV from rooftop solar in Germany: why self-consumed solar is worth ~29 ct/kWh more than exporting it, how PV surplus charging works, which wallboxes (go-e, Zappi, KEBA, Fronius, openWB) support it, and a conservative worked example of the ~€200–€350/yr saving.
Do you legally need an electrician to install a wallbox in Germany? Yes — §13 NAV reserves the work for a registered Elektrofachbetrieb, and DIY can void your insurance. What the electrician actually does, 2026 labour costs (€500–€3,000), and how to find a certified installer.
Installing a home wallbox in Germany is 2–6 weeks of process, and the paperwork — not the wiring — is what takes the time. The full sequence: feasibility, quotes, the 12 kVA §19 NAV rule, §14a controllability, grid registration, install and commissioning, with a realistic 2026 timeline.
Since December 2020 you have a legal right to a home wallbox in Germany. This guide pulls the three rule sets together — grid-operator registration (11 kW notify vs 22 kW approval), tenant consent under §554 BGB, and WEG-owner rights under §§20/21 WEG — into one clear decision flow and step-by-step.
A good 11 kW home wallbox in Germany costs €400–€700, so features decide, not price. A five-way comparison of go-e Gemini, Heidelberg Energy Control, ABL, Easee and Wallbox Pulsar — on price, smart control, dynamic load and the calibrated-meter question — with a which-box-for-whom guide.
