Micro Center is selling the Raspberry Pi Zero for 99¢ as a loss leader. I bought one, then spent another few bucks for a boot disk and a USB-to-Ethernet adapter and a minimal case. Total investment: about $15.
I’m using it as a Pi-Hole machine.
Have you seen the old man in the closed down market,
Kicking up the papers in his worn out shoes?
In his eyes you see no pride, hands hang loosely at his side
Yesterdays papers, telling yesterdays news.
How can you tell me you’re lonely,
And say for you the sun don’t shine?
Let me take you by the hand
Lead you through the streets of London
I’ll show you something to make you change your mind…
Have you seen the old man outside the sea-man’s mission
Memories fading like the metal ribbons that he wears.
In our winter city the rain cries a little pity
For one more forgotten hero and a world that doesn’t care…
