which uses the low current signal from the Uno to switch high current DC loads on and off in
microseconds.

The Uno also connects to 4 Dallas DS18B20 digital temperature sensors via a OneWire
network. Areas monitored: tent outside ambient, tent inside ambient, bulb temperature, and
heated blanket temperature. Pi CPU temperature is monitored separately via the onboard
sensor.

The Pi connects to the home LAN via a 150Mb Powerline Ethernet Adapter — reliable, low
clutter, no WiFi dependency. The Pi also runs Tailscale VPN, providing secure remote access to
the LAN and to CozZie Glow's web app controls from anywhere.

The Tent — A Sensory Sanctuary

It is now my sensory sanctuary.

A purpose built black fabric bed tent — queen size, purchased on Amazon — sits over my bed.
Not a camping tent. A completely blacked out personal environment that happens to be exactly
where you already sleep.

The concept is simple and brilliant. Total light isolation. Partial sound muffling — enhanced
further by a thick blanket draped over one side. And unlike a room you can't control, the tent
environment is entirely yours.

| think everyone should have one.
When | camp in the mountains, everything | need is in my tent. | can do most things from my
sleeping bag. The bed tent brings that same self-contained comfort home. Everything within

reach. Everything controlled. No need to leave unless you choose to.

Inside — two handbuilt mason jar lamps, cabling running through custom black fabric sleeve
sewn from an old pair of pants.

For someone managing migraines, hyperacusis, and light sensitivity — this is a recovery pod.
For anyone who has ever been woken by light pollution, a partner's phone, or a streetlight

through thin curtains — this is a solution hiding in plain sight.

CozZie Glow was built for this space. They belong together.
