Success from Failure at the Hardware Meetup

WE got this mostly working

First nothing would work. Then everything worked. The Hardware Meetup last night turned out to be all about RFID tags. I’d brought along some tags I was thinking of putting onto the Hull Pixelbot robots. And Ross had brought a reader and some very fancy tags that were sticky labels that can be used to measure the temperature of whatever they’re stuck on.

RFID (Radio Frequency Identification) tags are great for identifying things - the clues in the name. They contain a chip and a tiny antenna which gets power from the the tag reader. The chip can send and store data so that you can literally keep tags on things. I’ve used them a lot in the past. And the new tags are much more powerful - but only if you can get them to work.

At the start of the evening I couldn’t get read any of my tags. And nothing Ross had brought was working. But then things started to change. A network cable was obtained to connect the sensor reader to a network gateway that Brian had brought. Then software was loaded and fired up and, despite not really knowing what we were doing, we managed to connect to the tags. And I even got my tags working too. The next step is to build a tag reader holder into the front of the robot and scatter some tags around the robot arena.

The next meetup is in two weeks. I wonder what we will get working then?
