Neodymium magnets are everywhere so I thought it would be neat to give people some insight into how they are made. The process was far from easy or something that could happen in a reasonable garage laboratory, but it was described pretty well in a blog posting for a magnet retailer.
The functionality of the tag reader took shape. A good deal of time was spent trying to get the display to show the desired information. LCDs with the I2C backpack were surprisingly challenging to interface with, and it took a considerable amount of research and frustration to cobble something together. Sample test was finally achieved.
Tags could be read and displayed on the LCD panel which will be permanently located inside the enclosure. To demonstrate, a short video was taken to show two different tags being read while their EPCs were displayed.
There was a short break from programming so that an old garage door opener could be repurposed for this project. Screw terminals were installed so that an arcade button could replace the rotten button. The second set of terminals was installed so that one of the relays could also trigger the garage door opener.
In the hectic week, I forgot to post a couple of the days. Sorry about that.
The rest of the weekly summaries have been arranged by date.
