Library Self-Checkout hardware selection. My recommendations.

Image
So you're looking for hardware to build a self-checkout system for your library? How much should you spend? Here I will offer my opinion... You will need (1) a computer, (2) a monitor (or touch monitor), (3) a barcode reader, (4) a receipt printer (optional). For the computer, I would totally recommend the Dell Optiplex 3080 micro PC. 8GB, 256 GB SSD. These are available currently for about $650. Whichever PC you get make sure it comes with enough USB ports. This one has six. A touch monitor is nice. A 15-inch 4:3 ratio screen is best. While large widescreen monitors are fine they do not improve the user experience and can be distracting. Here are touch monitors from Elotouch and Beetronics. These cost around $500 to $600 depending on the options. I recommend the built-in speaker and desktop stand. Be aware you may need a video adapter cable to connect the PC to the monitor. (Such as Display Port from the PC to VGA on the monitor.)  If you do not wish to use a touchscreen, a regula...

My self-checkout software goals for 2023

 Hi again. Hope you've been well. Software can be kind of boring. No one really cares about most of the cool little features that we spend months developing. I mean, think about a utility such as a word processor program. I have used "MS Word" about every day since the early 1990s. How many features can you think of that were added since then that are really useful? Seriously, the last cool feature that I use regularly was mail merge. MS corp needs revenue so every year they release a new version of the software and hope people will buy the same software yet again. I used the 1997 version for ten years or so. Now I use the 2007 version. Office software is like a microwave oven or a toaster. They were pretty much perfected more than 20 years ago. Of course they can add bluetooth, and enable Alexa to inform you when the toast is ready. It will be cool when your robot can serve your poptarts in bed. So here's what I am currently working on: Camera integration. This is ac...

Some Very Important Acknowledgements

 I feel very grateful to my friends of the past. I now run a small business serving libraries thanks to some great people whom I shall mention briefly here. (This COULD be a long post, as memories flood back, but I will try to summarize my love and admiration for these people.) My friend Wayne Myers , who owned the successful "The Other Book Store" in Mystic Connecticut in the 1970s and 80s taught me to love books. In the 1980s he created a business, Bit Systems, Inc., and hired me as a programmer to develop software to manage bookstores. He was a true giant of a man and taught me so much about the world. In 2005, my first (and only) child was born and I was trying desperately to be responsible and provide for my family. I had recently lost my job at a fairly large food corporation and was feeling rather low and worthless. When Ron Faria invited me for an interview, concerning a programming position in his library service business I jumped at the opportunity. He was a great ...
