Gear UberNerds need that is almost universally super crappy:
KVM Switch(Level1 KVM WOOOO!)
- uninterruptible power supply
So maybe making a UPS that isn’t utter garbage is next on the level1 todo list. Anyone want to contribute?
My opinion is that the best UPS tech is, by far, a flywheel: https://www.qpsolutions.net/2017/06/intro-to-the-flywheel-ups-powered-by-motion/
Unfortunately, I’d like to build a UPS for an ubernerd that is also not wildly expensive. We were able to build a durn good KVM, one of the very best (though imperfect), that was also one of the least expensive KVM options out there. Can we do it again with UPSs?
It seems to me it comes down to the battery. I haven’t done any R&D on the battery yet, not really, but something easy and with a life of at least 5, hopefully 10, years would be ideal.
I think that rules out the standard battery type in most UPSs – sealed lead acid. These are hit and miss. the good ones can have a lifetime of 5 years but the cheap ones barely last a year.
Lithium Ion is out because it can’t wait to catch on fire and was not designed to store a charge for a long time.
A UPS built of super capacitors is something I have seen at computex. I will gather more info when I go there again this year (hopefully).
General parameters for the battery would be something that could cost less than $200 while providing something on the order of 250 watt hours of energy storage.
One other downside of super capacitors is that their voltage drops as they discharge unlike other battery technologies and it might be problematic dealing with that.
( It could also be my friend Eric sucked me into thinking about this… http://esr.ibiblio.org/?p=7839 and so… by proxy… I lean on you, the smart and good people of the forum. that reminds me. pls no trolling k thx bai)
