Smart devices, connected gadgets, embedded tech for makers.
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 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.
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.
That $10 USB logic analyzer in your parts bin can read the secret conversations happening inside your robot vacuum, fitness tracker, and every gadget in between. We walked through three real teardowns using sigrok and PulseView — here's what we learned.
A $150 mini PC, a Zigbee dongle, and a weekend of tinkering can replace every subscription your smart home leans on. Here's how we built a fully local automation stack — and what it actually costs to run.
From freezer loggers that text you before the ice cream melts to package cameras for the porch, these eight ESP32 builds keep watch while you're on the road. Each one is scored on build time, cost, and — most importantly — whether it survives a week unattended.
A $30 USB radio stick and Zigbee2MQTT can replace a proprietary hub entirely — and unlike that Samsung box, nothing gets bricked when a company changes its mind. Here's the full parts list, setup walkthrough, and the honest cases where you should just buy the commercial hub.
After a multi-day ISP outage left our block offline, I built a LoRa mesh network with Heltec and LilyGO boards that routes messages and sensor data without touching the internet. Here's the full build, real suburban range numbers, and what six months of battery data taught me about offline-first design.
Your garage door opener works fine — it just isn't smart. We scored seven retrofit approaches, from plug-and-play ratgdo to bare-knuckle relay wiring, on install difficulty, Home Assistant support, and safety sensor handling.
