You asked about the RFID module I used for my project. It is the SL018 module from Stonglink from China. It is low on costs and it fitted all my needs. I started my project almost a year ago and in april 2012 I decided to go for this module. Sure I wanted a gadgeteer module but it wasn’t available at the time. I wrote “all” the needed software for the SL018 and debugged it already before the module with SM130 became available. It will be used in my next project…
Thanks to all for the compliments. During the coming weekend (and maybe early next week) I will be writing an article about this project and post it here as a showcase. If there are any questions, I’m willing to answer them all.
