How do these compare to the Luxonis cameras? https://www.luxonis.com/


Not OP, but I'm very familiar with both.

Luxonis is way more powerful and has an Intel VPU (Movidius). It's not really meant to be a standalone platform, so it needs a host board (Linux SBC like the Pi). It takes a lot more power, but it can do 60fps on small Yolo models. Its resolution is a lot higher as well.

ESP32-S3 has a pretty small memory capacity, and doesn't have H264-H265 hardware encoding, so you'll be on low-res, low-fps. It only does MJPEG (AFAIK) streaming, so you'll also have to deal with high latency if you want to send that data somewhere. The big bonus is that it's low-cost and low-power, and you're running it directly on the core without an OS.

This means you can do stuff like sleep the cores until something wakes it up (like a PIR sensor that detects people), and it will start streaming in a second or two.

TL;DR: Luxonis stronk, but needs big batteries or plugged in. ESP32-S3 can run on small batteries or solar.


Ngl I really wish Luxonis cameras supported running standalone after being configured once, OpenVino is such a heckin chonker to install and manage.


The ESP32-P4 has hardware accelerators for media-encoding, including H.264. Might want to check it out.


Is it out yet?

I'm desperately waiting for it to be available.


Since they announced it half a year ago I would have expected engineering samples to be available by now, but there is nothing.


a couple person startup seems like a risky bet


> In the not-too-distant future, vehicles will charge when excess solar is available

Emporia Energy's smart EV charger can already do this. So can our $9 smart plug. Disclosure: I work there.


Big fan of your products :) Have bought a dozen of them personally.

From what I understand, excess solar is more common in markets that have asymmetric import/export prices, like Australia, that strongly incentivize self-consumption vs. exporting back to the grid. CA is likely to implement this with NEM 3.0 so we are likely to start seeing this shift in behavior in the US soon as well. Right now there isn't much of an economic incentive to do excess solar in markets with symmetric NEM compensation (I'm sure you know all of this).

Other problem we have in the US vs. AU is our cost of installation is so high that it makes oversizing systems somewhat cost prohibitive, which is what you'd need to do to get enough excess solar to charge an EV.

Third problem is where cars are parked during the day while the sun is shining, which may be tough for people who commute to work. Energy storage can obviously help here somewhat.


What camera hardware are you using? https://www.luxonis.com/ might be an interesting option.


We use off-the-shelf cameras (we just need an RTSP stream), but thanks for the input, we'll definitely check them out!


In Mexico last week an Uber was twice the cost of using inDriver. Our driver reported Uber taking 50% of the fare which is why so many users and drivers had switched to inDriver.


Buying real estate for short-term or long-term rentals is buying yourself a second job.

If you want something more passive, consider investing in several different real estate syndications. You can find them on CrowdStreet or FundRise although I believe you will get into better deals if you join a local investor group and learn from the experienced members. If there isn't a group near you, I'm enjoying participating in www.506investorgroup.com

This style is probably only practical if you already have a net worth of at least $1m. The best book I've found is Investing in Real Estate Private Equity by Sean Cook.

I think it is reasonable to expect a diversified portfolio of real estate syndications to return 10-15% annually although it will be bumpy and your money will be locked up for years.


Sincere question: why is this better than going with the vast array of mutual funds and ETFs available? Is it the return rate? Something else?

It seems like your typical ETF or mutual fund is easier to get into and get out of, just a few clicks on your brokerage of choice.

Your answer brought up the obvious general answer: the only way to make passive income from investments is to already have a lot of money. To me there's a point where the method of investment almost seems like an irrelevant detail.


I looked into syndication and commercial real estate earlier this year. My primary motivation was to diversify my holdings.

I ultimately bought a house where I could rent rooms out on airbnb or to renters instead of going with a syndication. The main factor was getting leverage: a 30 year mortgage at 2.8% APY is basically free money.

Airbnb is not passive, but I look at it this way: I'm going to live in a house anyways, I might as well get into the business of living.


This is what a lot of folks are missing- real estate investment returns aren’t necessarily higher than other vehicles but the leverage is awesome.


The leverage makes a lot of sense.

I do assume you can’t just take out a loan to join a syndication, but lots of people rent duplex units and vacation homes as you describe. Thanks for the answer!


You are correct that an ETF can provide similar exposure with much better liquidity (ease of getting in and out).

A few possible reasons to go private: a) smaller and more entrepreneurial operators can produce better returns b) capturing the illiquidity premium.


I knew a person running one of these in the UK. It was basically a massive con, where the investors took all the risk and he took all the profit.

So buyer beware.


The March 19th calls are at 500% volatility. I couldn't help it, I sold a few contracts of the 200 strike. The trading activity was wacky, every time I joined the option offer I got lifted within a minute.

I do not encourage anyone else to do the same. My risk tolerances are different from yours.


This is just a casino at this point where the underlying fundamentals are pretty broken and random on GME.


Where did the list of acceptable remote states come from?


Start a weekly or monthly investment in a Vanguard index fund of most of the extra. Leave yourself a bit, you've earned it.


This is fine investment advice... but the post isn't asking for investment advice. It's asking for advice on fighting lifestyle creep. Besides, there are a variety of ways to invest one's money, why provide only one vehicle as advice for investing?


The "invest most of it" was the way to fight lifestyle creep. If you've made it "disappear" into a Vanguard fund (or whatever), then you don't have it "available" to tempt you into spending it. You set your budget/expectations/lifestyle for what you have left after investing most of the surplus.


I think the idea is to give a very clear route for fighting lifestyle creep. Sure there are other options, but this is actionable advice. The question was also asking how do you do it so it may be how that user fights lifestyle creep.


Using RMSE doesn't make sense to me, your losses are linear to how wrong you are. Shouldn't the error just be how far off you were?
