I seem to be alone in my belief that batteries suck. Why are we adding more of these inconvenient, polluting monsters to our homes when good old fashioned wall power is there for us? In this video I’ll be exploring how to convert a battery powered smart home sensor to wall power for a total price of about 5 bucks.

9:50 did it work?
11:26 dan pls help.

Deals for Days. Big home savings are happening now.
Is it me or does Dan really remind a person of Lt. Barkley in Star Trek TNG?
I once converted a battery powered "toy" that someone wore out (contacts or switch didn't work on the battery anymore) to use an old 3.3V cell phone charger. It worked better than it originally did, although she didn't trust my expertise to actually use it after the repair.
I mean batteries in smoke detectors is still the move because of redundancy
I legit can't think of anything totally wireless in my house that doesn't leave the house, besides remotes and fire detectors… I'm sure there's something I'm missing.
I don't like the sponsor transition.
Love the more engineering-type content. I have 0 background in elektro or engineering but it's really interesting to follow these simpler things
Wouldn't it logically make sense to start normal sensor operation on batteries, then convert them after ensuring everything worked?
why not use the LD1117? its similar to the lm337 but haze a fix Voltage of 3.3V so no Vref to worry about. Its findable in a TO-220 case, so easy to solder and robust. I have those at home from aliexpress and was arround 3.30 euro for 10 Pcs.
Bruh using a resistor in series as a voltage divider is the worst way to get voltage down since it's proportional to the load resistance. Glad it worked out though lmao
I can imagine a plugin nerf gun now
Do yourself a favor and don't follow this guide. You can get switching step down voltage converters for very little money so you can have any output voltage from most power supplies. Also: a resistor is not a way to reduce voltage, because the voltage it drops depends on the current the device consumes. A diode is better in that regard, but if your goal is to get a lower voltage, you shouldn't use shottkey diodes but normal ones which drop the voltage by 0.7 V per diode.
How dare you take Adam savages saying lol 😂
Love Dan presenting. Get him in more videos!
@14:20 ghahaha so far with staying calm, great twist.
That sensor probably sends 1 data packet via RF every 10 minutes, its battery consumption must be extremely low
Dan needs to be in more videos, such a smart guy
Just a thought but since the device is designed for battery’s they might have designed it to draw the least amount of power it can to make the batteries last longer so could that mean if you made it wired that the device is energy efficient?
3 standard 1N4001 diodes in series should be perfect.
easyeda and jlc pcb would've been a better implementation
11:30 wish the video actually began here
I could imagine a really polished accessory that just slots in place of the battery and battery panel as a drop in mod for this. It probably wouldn't be hard to design
SOULDER. SOLEDER.
You know, it might have been easier to run the thermostat wires into the girls room and put the ecobee in there. 🤣
Probably don't call bumblefuckery a "guide".
Maybe next time use a regulator and a rather large capacitor on it's output. A battery IS a capacitor, and battery only devices won't have filtering caps for the ripple you tend to get from a wall power adapter.
Why not have a small PCB with the size of that battery made? Print something to fit into the back, use e.g. nickel strips to make contact between the PCB and the device. Now you have a CA$3 solution, but the work may well be worth it.
Voltage divider using 0.5w resistors is easier and it doesn't require soldering
There really needs to be an Adam Savage, Linus tech tips crossover.
I’m going to do this to my car fob, thx Linus 🙏🏼
Finally someone makes a video about all these battery powered sensors. I have done this exact thing to all of mine.
Use a damn 3.2v Zener diode .
Yea I've really been running up against this myself having most of my home smartified. I really wish that more smart home sensors came USB powered. I'm lucky that my house is small and I don't need to worry about multiple HVAC zones. One of the few joys of being self induced poor.
I LOVE that the multi-meter Linus grabs is battery powered!! LMAO🙃
Why, dear god, would you have soldiered it in before you tested the voltage….like wth.
glad im not the only one who noticed how good Dan has gotten on camera. not that he was bad before, but you can see the improvement and how comfortable he's gotten. i love anything involving Dan!
Can you do a video on converting an electric car to a gas burner? We all know those little batteries we use in our small devices are bad for the environment. Just imagine how bad those batteries in electric cars are going to impact the environment. Which is worse? Gas or Batteries?
Why film where you have to fog the background? Frame your shots!
Linus is lame
i never have batteries in my xbox controllers. id rather just use a usb cable
You could have used a tiny version of buck converter which costs less than 1$ and that would have been way easier than all the mess you did
A cheap board with the LDO presoldered to it is < $1 yet they make this look as jank and difficult as possible
LTT wire cutter coming soon???
I love Dan for saying solder correctly. My hero.
Couldn’t just move the thermostat to the other side of the wall? Nah, no video in that.
dan is the new linus and thats a fact
Now if only these stupid ecobee sensors would stay in stock
3 days ago Linus "batteries are bad"
2 days ago Linus "we're installing EV chargers for our employees to charge for free"
2nd, his strippers and multimeter make me cringe. He doesn't need the best for this type of work, but that's like dollar store garbage. He talks about all this e-waste in videos yet then buys those toys'r'us throw away tools? come on man.
