• One of a kind hobby project. I want to experiment with time of day controlled LEDs, and see how they work as a light based wake up alarm.

• I’d rather not break the bank for needlessly overkill connectors, the total for the project so far is only ~220$, and I only sporadically work on it.

• portability isn’t all that important, but the chassis the connectors would connect to should preferably be as small as possible. The PWM circuitry without connectors are ~8cmx3cm.

• I wouldn’t mind using connectors with more pins. The primary challenge is just finding a connector with both male and female socket plugs that seems to easy to plug in and out, within specs.

The connectors needs to be gendered so that input and output can’t be mixed up by mistake.

Sorry, my original comment was poorly written. While they do lead to earth, there is a mosfet in between each that receives a unique PWM signal. See the edit for more details.

By soldering the ends of the LED, do you mean the 4 earth connections? I should probably have clarified that the 4 “earth” connections only lead to earth when the mosfets connected to the LED is open. Each connection leading to earth is for either, R, G, B or W so they can’t be soldered together.

I haven’t noticed any difference in brightness between the first and last LED. Since the power is sent via PWM controlled mosfets, splitting the power wouldn’t work all that well since it inevitably have to connect the box (with the connectors) with the PWM circuitry.

I don’t know how aging affects the LED power draw, according to the manufacturer I shouldn’t expect more than 7.5A. When measuring peak power output, I get only get ~6A total though.

4 pins are for earth with each (measured) having ~1.5A going through them at peak brightness. The fifth pin must bear the total load of the four other pins.

Having 5 pins is of course not a strict requirement, it’s just the LED strip that has 5 connections.

Edit: I should have clarified that the 4 pins “leading to earth” are connected to mosfets controlled by PWM signals, so they aren’t directly connected to earth. Each of the 4 pins carries a unique amount of current. Their total current is flowing through the fifth pin. Sorry for missing out on that detail in the original statement.

A few meters LED strips.

According to the spec sheet only 7.5A should be necessary with a recommended 25% margin for a total 9.4A for the power supply. I rounded up to 10 for simplicity, and that’s the spec of the power supply I have.

Measuring max current at peak brightness is only at ~6A though, so 10A isn’t strictly necessary.

IP rating isn’t necessary, it should all fit into a small box with some circuitry for PWM signaling used inside a normal room.

How accurate is this map? If the Irish call football soccer, it would be most shocking thing I’ve learnt in 2024.

As I’m sure my home instance reveals, I do like the idea of focused instances. I think a general sports focused instance would be better than sport specific instances though, at least with lemmy’s current size. It’s not sustainable to pop up an instance for every sport out there, like strongman or arm wrestling.

And people would also have to be able to sign up to the instance. Which if I remember correctly you had a very different opinion on when you spoke to Snowe on !meta@programming.dev about programming.dev. Just from a technical standpoint, the federation latency and general wonkiness is real and is why my football bots are running on Lemmy.world despite programming.dev being my preferred instance. Near real-time communication is important during live games where minutes may drastically change the topic.

And while I’m sympathetic to your cause, inertia is a real thing and lemmy.world is competently run, even if I strongly disagree with their VPN restriction.

If you somehow managed to convince the other sports communities to migrate to a common instance I’d happily follow along though, but I find it very unlikely happen. ReadyUser31@lemmy.world is the one primarily in charge of !football@lemmy.world

I’d be interested in hearing the thoughts of some admins - would !football@lemmy.world be interested in moving to !football@soccer.forum, given the right organization?

I’m not the main mod of !football@lemmy.world so it’s really not my decision to make, but moving the community to a domain with the word soccer in it is a tough pill to swallow. As silly as it may sound, there’s a lot of people that don’t like having football referred to as soccer.

Moving away from lemmy.world and their annoying VPN restrictions would be nice though.

Yeah you’re right, local neighborhood militia sounds much better /s

The police do a valuable job if you’re living in a functional society.

Once operational, the energy generated is cheap and will still be in demand

No. Different genre at this point

I can’t remember ever having used meta critic to guide a purchase. There is so much content both from forums and YouTube/Twitch that gives you much more accurate impressions of games. Meta critic seems rather pointless nowadays.

It’s a genuine concern though. If you want one centralised server hosting all the content, just use reddit.

As a Norwegian, that got to be our coolest stat, however I have no idea how it can be true. Even in my engineering bubble there aren’t that many people using Linux. It’s all Windows and macs for home computers.

I don’t think you become the best tech CEO in the world by having a healthy approach to work. He is just wired differently, some people are just all about work.
