This is the second version of my barcode generator that I built. This one uses a lamp display and is completely re-usable. In this version I do not use RSNor latches, I use D Flip-Flops which allows the user to be able to change the input a new barcode without having to clear the barcode. The lamps are powered by a vertical torch stack which makes them update slowly and out of order, but I was unable to figure out another way of powering a 1-wide column of lamps that can be stacked. This version is also a lot smaller than the last version as it does not have to do any of the piston pushing or sand dropping. This build did not take that long overall and I had a ton of fun building it, I had to figure most all of stuff out, it was not so much just plugging together previous stuff to make something, which is why I made the video on the D Flip-Flop yesterday.
If you are too lazy to calculate the check digit by yourself, there are a lot of tools online that will calculate it for you, so I will not put all that information in this description (the online calculator also tells you how to calculate it), I will leave it in the other version though.
Thanks for Watching.
