Some of you may remember me as a NUT contributor years back - I did a significant amount of work on documentation, and later moved the repository from Subversion to GIT. I eventually drifted away from the project in large part because I found the lossage from lazy, least-cost-is-everything product designs too annoying to deal with. I recently had a bad experience with a UPS that brought all my frustrations back to the surface. I described it here, at "UPSes suck and need to be disrupted": http://esr.ibiblio.org/?p=7839 In 2018, the rise of makerspaces and short-run manufacturing means we have options we did not when I last collided with this technology. Today I think we could design and build an open-hardware/open-source UPS for personal and SOHO use that would put a floor under the commercial market, forcing the vendors to up their game. (It would be OK with me if "upping their game" consisted of putting this design in volume production and profiting from it.) The response to this proposal has been intense. It wasn't just me; frustration with this product category turns out to be widespread. People have offered to throw engineering time at it. I've gotten a lot of "Please please please run a kickstarter and take my money!" Last night the guy who runs the nearest makerspace to me recruited himself onto the project, which means we have shop space and tools for a serious build. I've started a project at GitLab: https://gitlab.com/esr/upside So far it's just a wiki for collaborative design. My goal is for it to become a complete design - schematics, COTS parts list, assembly instructions, qualification procedure. One problem with this plan is that I'm a software guy, not a hardware engineer. I can read spec sheets but I haven't a clue about designing and implementing power-switching electronics. (What I can do, and am doing, is develop the requirements list. In effect, I'm the product strategist and market-research guy.) UPSide needs a lead hardware engineer. This dev list seems like a good place to find one. If the concept interests you, please respond. It would be OK if you work for a UPS vendor; I get it about low margins making NRE spending difficult and I'm fine with a for-profit outfit using our enthusiasm to improve its product. The point is to *solve this problem*. And if we can create a precedent for positive-sum cooperation between open-hardware/makerspace hackers and industry, that's good too. -- <a href="http://www.catb.org/~esr/">Eric S.
