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.

200; It's pretty hard to play if you're dead

Anyone who thinks differently is not for you. People can do almost whatever they want for fun, as long as it's legal. Labeling someone childish because they like something is stupid; what am I going to do, drink all day, go to bars, hike, travel, play sports, do n'th paid activity, etc? Some people have the time, money or health that allows or disallows them to do these things, and some people do or don't have the interest. Tons of people enjoy watching tv shows. Are we supposed to grow out of that too? By that logic, we shouldn't enjoy anything we did as kids and just do things only relegated to adults.

Id say most people regardless of when they were born think like this unless they themselves play games. It's more socially acceptable amongst the younger generation right now (e.g. college graduates) and probably because they're still considered young. Kids have more free time than adults and the barrier to entry for them is low. Parents often see their kids playing games and in genral have a negative attitude towards them for consuming time. Id say as people go into their 30s and 40s its considered less acceptable because societal expectations are that people will work and get married and have kids by then, and they'd have less time for solo activities. Going to the bar while having young kids or other activities is less acceptable. As kids get older their parents have more time for fun, but playing games is seen as childish because they either see their kids playing or because its something from their own childhood and other ventures that cost money like travel are now available to them when they werent as kids

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.
