In the Wikipedia page there’s this formula

Just plug in values for the fence voltage and led. You can just set vswitch to 0 and Vled to 2V. It should be fairly insignificant compared to the fence voltage. It should be 10-20mA (0.01-0.02) to not kill the led.

The root of this is Ohms law: V=IR. Diodes cause a voltage drop rather than directly acting like a resistor which is why it’s subtracted from the input voltage.

Just put them in series. Make 2x, one in each direction to account for AC and DC

There’s lemmy 411 for trying to find relevant communities

I think he meant to reply to the main thread (which he did with the same comment) but didnt delete this (or maybe it didnt federate?)

Not related to the article, but this seems to have posted twice; is this a double post bug? Or did you manually submit it the second time (i.e. first time errored out)

Thats not even accounting for all the bots, alts and inactive accounts; it wouldnt surprise me in the least if the majority of those were bots or throwaways. Another benefit of lemmy’s setup is that individual servers will be fairly small so theres tons of space for smaller communities with higher quality discussion, even if it does end up causing duplicate communities across instances.

Can you? Yes

Should you? Probably not. High resistance and bad contact

Ah. It’s not going to be possible to size it because the bulb is then acting as a resistor essentially. Unless you know what the equivalent resistance of the circuit you’re testing is, and it draws a fixed current, you aren’t going to be able to cap the current; Adding a resistor (or bulb) is just going to drop the input voltage and you will probably end up having other issues

For this application you should be using a bench power supply with current limiting, not a “serial bulb” (I assume you mean a fuse, which is designed to break at a low current, however these are most typically rated for several amps, not typically in the mA range). You can set the voltage and a current limit. If the current goes beyond the limit, then the power supply will drop the voltage to keep the current below the limit or latch off. You can get a fairly cheap one for about $50-60 off of eBay, which won’t be the best but is sufficient for hobby use

Id wager that they dont put too much money into R&D and just pay one guy to port over the same code from their last last last generation printer to the new one. Over time its become an unrecognizable mess that is just hacked into working and no one ever takes a look under the hood. Their main market is the ink anyways, so making the printer good at what it does is an afterthought

kbin.social had federation break due to cloudflare

kbin.social might not work because they enabled cloudflare ddos protection during the large migration due to the blackout. This broke federation because the site would hit a landing page with a captcha instead of the actual site when trying to poll the api. Not sure if that’s been fixed since.

In any case, it should work either way if federation is enabled and working.

Freedom of speech is from consequences from the government. That means you cannot be prosecuted for insulting politicians for example. But you can certainly be sued in civil court for the same thing.

I dont like battle royales

Most of the time is spent just trying to get equipment or running from point A to point B, and by the time you’ve spent 15-20 minutes just running, one encounter means you lose

I play CS:GO. I like it because its more constant decision making, and the shorter rounds means less time investment into a single round. But it has gotten so bad with cheaters. I have played CS for over 15 years and yet I constantly run into brand new accounts or accounts that were clearly boosted (500+ commends in each category), bought, and used by cheaters who said that “it was cheaper than rust…” The matchmaking is so atrocious, I have people at the bottom of the ranks on my team and top of the ranks on theirs; the averages arent even close. I’m not playing CS:GO anymore and if CS2 doesnt fix the cheating problem, I’m not going back.

Hmm, Im in dark mode but it might be because of OS settings

Neither am I
