Smart devices, connected gadgets, embedded tech for makers.
Behind the drywall of countless American homes sits a treasure most people forget: abandoned Cat5 from a decade of rewiring. Here's how I turned leftover Ethernet runs into a PoE-style power and data backbone for my ESP32 sensor fleet — no new holes required.
When my HOA flagged my antenna as a 'harmful transmitter,' I didn't argue — I brought data. Armed with a $30 RTL-SDR and a free spectrum analyzer, I mapped every radio wave floating over my suburban backyard, including the ones my neighbors already owned. Here's how a waterfall display settled the dispute, plus a plain-English guide to reading one yourself.
You don't need to own the walls to own your smart home. Here's the gear I've dragged across three apartments that installs in minutes, leaves drywall untouched, and still works when the next lease starts.
I retrofitted my 2016 travel trailer with a fleet of ESP32 nodes tracking battery voltage, propane, fresh water, and door security — all without a single wire to the grid. Here's the full build, including what broke when I hit the highway at 65 mph.
I spent seven evenings driving my own cul-de-sac with a laptop, a GPS puck, and a Wi-Fi scanner, logging every smart doorbell, sprinkler controller, and EV charger broadcasting to the street. Here's what leaked, what didn't, and how to lock down your own porch before a stranger with a $30 adapter comes knocking.
You don't own the walls, but you can still own the automation. Here's the no-screw, no-drill kit that turns any apartment into a smart home — and packs back into a single bin on moving day.
Living under an HOA doesn't mean giving up on a proper smart home — it just means your hardware needs to keep a low profile. Here's how to build a full sensor fleet that lives inside baseboards, attics, and wall cavities, with zero visible antennas and zero angry letters in your mailbox.
I pulled a chunk of my smart home completely off the grid — a used deep-cycle battery, a bargain solar panel, and a fleet of ESP32 sensors and lights. Here's the capacity math, what died first, and whether gadget energy independence is actually worth it.
I spent a month building a subscription-free ESP32-CAM doorbell with local-only storage. Then I handed the IP address to a security researcher and watched him tear it apart. Here's every finding, every fix, and the checklist I wish I'd had from day one.
We cracked open a smart refrigerator, a Wi-Fi oven, and a connected coffee maker to see what kind of radios actually ship inside them. The results were embarrassing — and they explain why your kitchen is a dead zone.
We put a popular Wi-Fi robot vacuum behind a monitoring router and watched every packet it emitted. The floor plan leak is real — but so are the fixes, and none of them require a soldering iron.
Your furnace, washer, and sump pump are decades old and utterly mute — but with a current clamp, a vibration sensor, and an ESP32, they'll start texting you before things go sideways. Here's how I gave my analog fleet a voice without spending anywhere near the cost of a replacement.
Armed with a $15 metering smart plug and an ESP32 energy monitor, I spent a weekend measuring every device that sips power while 'off.' The worst offender? A gaming PC that burns more wattage asleep than my fridge does running. Here's the full audit, the numbers, and a subscription-free dashboard to track your savings.
Your smart bulbs aren't dumb — your Wi-Fi is just crowded. Here's how to find out who's hogging the 2.4GHz band, why your microwave is a suspect, and the router settings that finally made my smart home feel fast again.
I wired every appliance in my house into a local MQTT dashboard and spent a month drowning in telemetry. Here's what a normal home actually generates — and the filtering strategies that saved my sanity.
I've murdered more houseplants than I care to admit, so I built a soil moisture system that texts me before things get dire — and waters the plants while I'm in Vegas. Here's the full weekend build, from capacitive sensors to Home Assistant automations.
Cloud doorbells promise convenience, but they're quietly shipping footage of your porch to servers you'll never see. We built a Raspberry Pi replacement that runs Frigate for person detection, keeps every byte on your own network, and came in under $100.
We put a no-name $12 hot plate head-to-head with a mid-range unit across three real maker projects, from QFN microcontrollers to 0402 passives. Here's what the temperature data, solder joints, and smoke revealed about whether cheap reflow is actually viable.
Your router, TV, and game console are already running 24/7 — and every one of them has a spare USB port. Here's how to safely siphon 5V from the electronics you already own to power sensors and microcontrollers, no new outlets or batteries required.
Your bricked smart speaker isn't trash — it's a repair challenge. Here's how a budget hot air station, a USB serial adapter, and some patience can resurrect gadgets the manufacturer gave up on years ago.
