I think Lemmy would either need to find a way to wean Redditors off of their dopamine machine or replace that dopamine machine long-term to sustain an exodus from Reddit. Either that, or Reddit will need to break their dopamine feedback loop. There are some cracks showing, and that might have already killed the platform in the long term, but it’ll keep going from pure momentum for a while. Maybe as long as months or years.
Seems like there’s more sexists and racists than I used to see over there, which is definitely offputting. I’ve found communities that are supportive of thoughtful discussion are more appealing, and Reddit definitely lacks that lately, outside of some small, relatively niche communities.
Never been part of that community personally, but thanks for helping to support the platform. Even if you’re not seeing much traction, it’s appreciated. What would you think of picking the most engaging Reddit content and migrate it here to help boost community size? Or maybe posting to Reddit with a watermark/credit leading to your Lemmy community?
I could be mistaken, but many years ago I believe I learned that plywood is generally made by spinning a log while slicing a thin veneer off the surface, then stacking multiple of those veneers into plywood. The grain on the surface would be notably different when cutting wood with this method compared to sawing planks
Hello, I have a circuit that will need to return connected hardware to a default state if power is lost. The hardware can handle continuous voltage, so I’m thinking a simple solution would be to use a battery to provide that fallback power source. To avoid draining the battery, I’d like to connect it through a relay on the...
Thanks, that’s good to know! The datasheet doesn’t seem to include the word “duty” anywhere, so I think that must have been omitted. Ostensibly that means the maximum duty cycle is unlimited, but I don’t have enough experience here to say that with any confidence.
Thanks, I don’t think there are any external settings for the power supply, but it does provide a few more volts than I strictly need. Toggling a single relay hasn’t caused me any issues in the limited testing I’ve done. A momentary drop to as low as 5V should be perfectly fine, although, looking over the specs for my components, I see I’m getting dangerously close to the upper limits for the power supply’s current rating. I’ll have to look into connecting 2 supplies in parallel (or getting a larger supply) I suppose.
I haven’t worked with battery backups yet, so I was thinking it would be best to keep that element simple to minimize potential issues like a trickle charge draining the battery unexpectedly, or damaging the battery from overcharge. The minimum requirement is just to ensure the hardware (a motorized ball valve) returns to a closed position if power is lost. The battery needs to provide at least 9V to power the motor, so I could use a 9V (or a few smaller cells in series) to keep it below the 12V supply.
With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery? If so, in that configuration I’d need to do more research and figure out how to use a BMS, rather than an externally recharged or disposable cell.
I’m a little new to the terminology, so to clarify, the switching current refers to the amperage across the terminals other than the coil, right? I’m definitely within those limits; I don’t expect to transfer more than ~1/8 of the maximum amperage.
Is there a rule of thumb for the minimum current I should allow across the coil? The only specification I see on the datasheet for coil amperage is that it was tested to failure at 100mA. I don’t think power consumption is too big of a deal with this use case, but resistive heating sounds like it could shorten component life (and even if it’s only a secondary consideration here, I’d still prefer to minimize waste).

The great thing about doubting yourself is that it makes you feel so ahead of those self-confident suckers.
