    Capacitors can be used to remove ripple from a DC current. Ripple is basically alternating current that is running along a DC current. So, attenuation, I believe, is the correct terminology.

    They generally don’t completely get rid of AC, and they don’t perfectly filter it out unless they are perfectly matched for the AC, and even then, I don’t know of any capacitors that are used in lieu of a full-bridge rectifier or half-bridge rectifier to convert AC to DC.

    I could very well be wrong. I am far from an electronics expert, But this is what my understanding tells me.


  • And when they are used for air-conditioning units, they are typically boost capacitors, which means they store up a nice amount of juice for when the compressor powers on and needs a sudden rush of energy, but that’s only a very small amount, like you couldn’t crank a car with the amount of energy in these capacitors.









  • Just so that I get this out while it’s fresh on my mind, what’s wrong with the internet right now is cyberfeudalism.

    The internet is essentially an infinite world, so no matter how much the large companies gobble up, we’ll always be able to go somewhere else.

    That being said, it gets really fucking exhausting to move over and over again to different apps and different locations just so to talk to people without some greedy, megalithic corporation there, snooping on everything you say and ingesting your words to feed some abomination intelligence simulation or to figure out the best way to sell you a new pair of fucking socks.

    All of that being said, I’m just saying it fucking sucks to continuously be a refugee, and what sucks about apps and companies and programs that end up selling out for a dollar is that if you don’t emmigrate to a new platform, you become nothing.





  • Well, there’s nothing wrong with that at all. The only thing I was thinking is that you would then also have the rest of the Proxmox server to do other server things with.

    For instance, you could set up an LDAP server and create a centralized login for your home domain And have that separate from your portainer setup so that if you make a mistake you don’t end up having to redo your portainer setup.

    You could also use it as a VM host to try out different flavors of Linux and see if any of them make any more sense to you.

    Even though it’s not recommended, you could also host Truenas on top of Proxmox.

    There are good reasons to use virtual machines separate from another virtual machine.


  • Like the other people said, use Proxmox. Just download the installer, flash it to a flash drive with Rufus and install it and then put it somewhere far away where the noise won’t bother you hopefully plug it into your network and then you can just run it.

    One thing that I like to do is to install ubuntu server and then install Docker and Portainer on the server and then you can just run a whole bunch of Docker containers and have a lot of fun playing around with that.

    There are a lot of guides for how to do that, but if you set up Proxmox first and then create a VM with, say, four CPUs and four gigs of RAM and 40 gigs of storage space, you’ll have more than enough room in that one virtual machine to run dozens of net services.

    Some good ones to install are pihole or ad guard home and nginx reverse proxy.

    You can go to DuckDNS and create a subdomain and then set the IP address to your internal ip.

    Once you have that up, you can then go to Let’s encrypt and create a wildcard certificate and then give all of the services you’re running on Docker and on your NAS server an internal name with an SSL certificate instead of having to type in the IP addresses.

    The sky is the limit and the more things that you play around with and try, the better you’ll get at them and the more things you’ll learn how to do.




  • I’ve noticed that when I am specking out a new computer I typically fall into the trap of wanting the absolute best computer I can get for the money.

    I’ve always been on the cheaper side, so I have found myself spending days or weeks researching various parts at various quality levels at various prices.

    It becomes a huge drag.

    Set the budget that you’re comfortable with, find the motherboard that has the features that you want, then get a CPU that fits in that price range, a case that fits your use cases, and then if you’re going to splurge on anything splurge on the power supply as a good power supply can last you through multiple computers.

    If you have to save money somewhere, save money on RAM as you can always order more or upgrade the rim that you have relatively inexpensively. Maybe if you’re going intel, purchase an i5 CPU and then consider upgrading if you max out its abilities or you find yourself frequently running at 100% utilization.

    And don’t overlook pre-builts. There are lots of refurbished computers that you can purchase for far less than the cost of the individual parts that have all of the minimum specs that you want in exchange for little things like only having a single stick of ram or having a low quality SSD.

    There’s nothing that stops you from upgrading later should your use case change.
