  "Starlink is only for the rich or for big offices!" — that’s what many people think. But actually, that’s not true. With a little effort and some smart planning, even ordinary people in villages — shopkeepers, rickshaw pullers — can use this high-speed internet if they come together as a group. How is it possible at such a low cost? Let’s break it down: Starlink’s monthly bill is around 4,200 to 6,000 BDT. That may seem expensive for one person, but if 20 to 25 people share the cost, it becomes very affordable: Monthly cost per person (if 20 people share): 4,200 ÷ 20 = just 210 BDT! One-time setup cost (dish, router, etc.): Around 50,000 BDT (only paid once) So even a rickshaw puller could use high-speed Wi-Fi by paying just 200–250 BDT per month! Here’s how it works, in simple steps: 1. Install the Starlink dish in an open space with a clear view of the sky. 2. A cable runs from the dish to the Starlink modem. 3. The modem is connected to a Wi-Fi router. 4. The ...

Summary Lower power draw matters in the long term: Pi sips power compared to a NAS, saving on energy costs. Keeps storage and security separate: isolating firewall on Pi avoids conflicts, maintains stable performance. Easy to re-flash, upgrade, or swap: Pi setups are quick to reset and experiment with different tools. When I decided to tighten up my  home network security , I had to choose between using my NAS or a Raspberry Pi as my firewall. While both are powerful tools in their own right, I quickly realized that the  tiny Raspberry Pi  offered some particular advantages for this job. It gave me more flexibility, used fewer resources, and didn't interfere with my core storage services. Here’s why I stick with a Raspberry Pi whenever it comes to deploying a firewall.
