How to build a Uber UPS Backup Sytstem

Here is how to build my Uber UPS Backup System on the cheap. First you will need to obtain a suitable UPS unit to start with,  I recommend at least a 350 watt unit.  I picked up mine at the Goodwill store for $6.00. After that it’s quite simple. Remove the stock battery, that is usually bad if you get one at a 2nd hand store like I did, and crimp on two quick release connectors to the red (+) and black (-) battery connection wires. Then do the same with the wires going to your new batteries. The wire size for the battery connection should be no smaller than 12 gauge for this project.  I suggest that you always go male/female to the UPS unit and also on the battery cables so you won’t be able to accidentally reverse polarity.  If you are using more than one battery like I am it’s also a good idea to put a in-line 10 amp fuse between the batteries for overload protection.  For the batteries I use two AGM 35 amp sealed lead acid batteries.  You should be able to get these from your local battery speciality store or if you live in the St. Petersburg, FL area go to Electro Battery  where you can pick up a refurbished battery for around $25.00.  I also recommend that you use your soldering iron and tin all of the wire connections for circuit reliability.  When you are finished, put a load on the system and test it by unplugging the UPS unit from its electrical source. As always if you have any questions on this build you can contact me for assistance.

St. Petersburg Makerspace

I took a tour of the St. Petersburg maker space today and was so impressed I joined immediately. I am looking forward to spending a lot of my time there working on new inventions and projects.

What is a makerspace? Also known as hackerspaces, hackspaces, and fablabs, makerspaces are creative, DIY places where people with common interests gather to create, invent, collaborate, and learn. In an open community lab, workbench, machine shop, or workshop environment, people share resources and knowledge. Makerspaces often have 3D printers and various fabrication tools, and related software, electronics, craft and hardware supplies, and more.

St. Pete Makers is part of a growing global makerspace movement that is based on collaboration. We provide an opportunity for creators to connect with each other and with the larger community.  We are a collection of builders, makers, and artists. We promote science, technology, engineering, arts, and mathematics by providing resources, teaching classes, and participating in events. Our members use our makerspace to work on projects, share ideas, and help each other create that which they have envisioned. Visit http://www.stpetemakers.org for more information.
