Eric S Raymond’s UPS Rant and Solution
I use a UPS (Uninterruptible Power Supply) to protect the Great Beast of Malvern from power outages and lightning strikes. Every once in a while I have to buy a replacement UPS and am reminded of how horribly this entire product category sucks. Consumer-grade UPSes suck, SOHO UPSs suck, and I am reliably informed by my friends who run datacenters that no, you cannot ascend into a blissful upland of winnitude by shelling out for expensive “enterprise-grade” UPSes – they all suck too.
ESR is very unhappy with the state of UPS power supplies and he is hoping for an open-source, easily buildable design could change the landscape. At the moment the focus is on just pushing out the PCB schematics and design for such a unit with users left to build the UPS yourself, but he has said he wouldn’t mind if some startup or other company ends up making use of these open-source plans to bring a better UPS to market.

The Upside project is hosted on GitLab and “is currently defining requirements and developing a specification for a ‘high quality UPS that can be built from off-the-shelf parts in any reasonably well-equipped makerspace or home electronics shop’.”
