One word to the costs. arduino uno: 16.10 (bought in China) Ethernet-shield Wiznet5100: 22,50 (bought in China) RFID-Shield Adafruit 789: 44.83 (bought from watterott electronic in Germany)
That is 83.43 incl VAT an PP. Now one word to the RFID-cards. I ask a lokal retailer if he had some cards, that he could not use anymore for a good price. I told him I need them for testing. Fortunately he had some - round about 400 pcs. But there was the problem with the price. I must say I am retired (age 65) and have more time than money. :-) So I offered him to work three days for him - he agreed. Lucky me! Most of the cards come from china and the quality is not constant as good as it should be. Sometimes the thickness of the cards is too much, so they cannot be printed in automatic printers. That are the cards we wanted! Ask your lokal retailer - good luck. For new cards the regular price would be about 50-60 eurocent/card if you order 100 plus. I think it would be great for listen CD and internet Radio for handicapped people and little children. You can place the reader card under the caseboard or the tableplate. The range of the shield it nearly 10 centmeters. You are right, there was a project similar to mine. I tried to get the documetation, but was not successful. Therefore I decided to realise it by myself. I hope there is time enough for making a small clip on youtube this week. musicmaster ------------------------------------------------------------------------ [email protected]'s Profile: http://forums.slimdevices.com/member.php?userid=47731 View this thread: http://forums.slimdevices.com/showthread.php?t=97891
