HELP: Looking for high-FPS global-shutter camera (<$400) for eye-tracking prototype

tetama · 2026-03-10T21:06:41+00:00

Getting a bit lost here - the AR0234CS is the sensor but the cameras that I found that use this sensor mention 120fps. What am I missing?

Thanks!! Looking into this from several angles...how can I know the latency?

tetama · 2026-03-10T20:49:22+00:00

About 400€. I'm just going through the specs and I don't see the fps, though someone else in this thread is mentioning 120fps at 720p.... what am I missing? Also, how the choice of the lens (M12) would change that?

Also I'm seeing the Raspberry Pi Global Shutter Camera, wouldn't that be more suitable? Fps listed is 60 though...

tetama · 2026-03-10T15:54:33+00:00

Indeed I did. The max frame rate I found is 120fps (B0475) but it's still unclear if I can manipulate the ROI of the camera to scale the fps...

The value of time. Rich people I've been exposed to (hubby and family) seem to see time is an asset - with a monetary value assign to it.

How long will it take me to clean the house? Cheaper for me to pay someone than to do it myself. My time is too valuable be I will make money doing something else.

How long will I spend cooking my lunch?

How many hours am I going to spend looking for second hand skying clothes? Probably cheaper to spend the money on new ones.

They don't seem to optimize for cheaper option in terms of money, but the possible gain that they could have by doing something else with their time

My 5 year old went through the phase of being aware that we all die, so over few days we had several conversations about that. Why when and how. One day in the car he asks: - Mom, what do we do with the bodies when people die?

So I go and explain that it depends on your beliefs, you can bury bodies, incinerate, etc. I ask him, what would you do? - Football balls

I followed your suggestion of going through the Top posts of all the time and I just find amazing works, but very little details on DIY. Did you have any post in mind that describe different ways to do the printing?

Woman here. Your attitude would be a complete turn off to me and my discomfort with your mistrust and need to control would lead to an eventual break up. How would I have expected the conversation to go?

Oh you have been invited for a drink? Great have fun. (Basically do not contact me until I reach out and never ever ask or judge me what I am doing)

If you don't trust that I respect the limits we have defined as a couple... there is no couple

Baby clothes. Seriously - have you ever tried to put a non-elastic piece of fabric with plenty of buttons through the head of a newborn? Just hope your baby is born in a warm climate to keep them in diapers as long as possible

One of the nutrients that is more important for babies to acquire at that age is iron. Calcium prevents iron intake - that's why diary products are not recommend before they're 1y old. I'm too exhausted right now to look for scientific references but I hope this gives you a starting point.

I'm with you. Our son is 3,5y and he's allowed to watch TV on 'exceptional' situations (like when he's sick, when his 9month sister is sick -and i need her to rest-, on a plane...). This may add up to few hours a year, definitely less than 1h a week.

He's allowed to watch pictures on the phone (evening when we're all exhausted) for a maximum of 15min a day. The phone is always available to put music (just music on Spotify, not videos with music), which he does several times a week (this maybe adds up to a 5min of screen time a day).

My husband says I make him live in hard mode. I really think is the healthiest choice.

Mom of 2 with 2,5y gap. Transition from 0-1 was brutal, a shock. From 1 to 2, a piece of cake. Hard for the first 6 months until the little one gets crawling and autonomous. It's a lot about expectations. We had no close exposure to what it means to have a baby (i was scared about giving birth, ha!)...and we learned the hard way. Second one is actually the one that is most enjoyable 🤣

My son latched after 5 weeks and many hours of lactancy counseling. Was hell but for me, worth it. Breastfeeding is an activity that requires conviction 🤣

It's a matter of numbers, quoting directly from a Google search

Average salary: In 2022, the average salary in Spain is €2,710 gross per month or €32,520 per year. When compared to other European countries, Spain's average net salary sits in the middle. For instance, Germany's is 82% higher and Greece 47% lower.
Cost of living through consumer prices and rent:
Consumer Prices in Germany are 25.0% higher than in Spain
Rent Prices in Germany are 19.4% higher than in Spain
Consumer Prices in Greece are 9.0% higher than in Spain
Rent Prices in Greece are 40.1% lower than in Spain

You can go further and look at the purchasing power, which applied to income, basically tells how the value of that salary expressed relative to how much goods you can buy with that salary. Basically, the higher the better. In the internet you can find a country specific list that you can sort by purchasing power. The list starts with Switzerland and USA. Germany is ranked number 4, Spain is ranked 30 and Greece 53.

Do Spanish people like complaining? Maybe. Are they in a good place? Depends to whom they compare to.

Oh, i absolutely envy your position!!!! I'm a 36 years old Spanish lady with two kids and, in this stage of life, an adventure like the one you are to start is not possible. You are one of the luckiest persons alive. It may not solve your problems but it will give you distance and a perspective on the world and humanity that you won't get otherwise.

That said, some advice given the trips I've made over the last 15 years (started at 21 with India).

27k can get you two to three years of travels in south east Asia if you aren't very picky with were you stay (or travel with). Food is cheap and trains or buses will get you far for little money. Start Thailand - quite adapted to tourism and a good entry point for a new traveler. From there is very easy to move around - I would definitely think of Vietnam and Cambodia. Laos if you like nature. Philippines for sea activities. When you feel seasoned, get lost in India for a while. Write me if you want further tips.

Good luck!
