About This Group

This group provides support for those using RFID technology to study animal movement and behavior.
  1. What's new in this group
  2. So, Hendrik, of Labmaker GmbH, has discovered the location of the new ETAGRFID firmware that I couldn't find. He's a true hero. Thank you, Hendrik. And here's the link: https://github.com/Eli-S-Bridge/ETAG_V10
  3. I received an ETAG_RFID board from Labmaker. The serial output at startup includes features not seen in the ETAG_4095 sketch I found online dated 5-4-18. New setup features include I = Set device ID, M = Change logging mode, and W = Write flash data to SD card. Can anyone point me to the repository or send me a copy of this alternate sketch? I want to know what I may overwrite with my changes, and not shoot myself in the foot!
  4. The move is done now. Let me know if you have any questions about how this new Groups feature works.
  5. Recently we started using a new application on OE called Groups. As a result, you now see a Groups tab on the navigation menu above. With this application, users can start their own sub-communities on OE, like this RFID Working Group. Several new groups have already been created, and more are on the way. I a now beginning to transition our existing groups to this new app. On Friday February 15 I will pull the trigger and have this forum moved over to the Groups app. Here is what to expect: The forum will be moved from the Forums page to the Groups page. When you click on Groups in the navigation menu, you will see a list of groups, including the new RFID Working Group. When you click on the group, there will be a home page, a members page, and a forum page. The forum page will look just like the current one does. All the past forum topics will be there too. Anybody who is signed up for notifications on the current forum will be added to the new group and your personal notification settings for the forum will be maintained as they currently are. Eli Bridge will be the owner of the group, and the moderator. If anybody else wants to help moderate, talk to Eli. If anybody has any questions or concerns, please reply to this message or contact me directly. And if anybody has an I can use as either a logo or a banner for the new group, please send it to me.
  6. I know the ETAG readers (arduino-based) are the new gold standard, but there are a few limitations to them that have left us wishing for some of the old school RFID reading units. In the past, we had ordered them pre-fabricated from "Cellular Tracking Technologies" but they no longer have them in stock and do not plan to make any more. I do not know who originally convinced that company to make some... Does anyone know of a supplier who has already pre-fabricated some of those older RFID readers? We could use some to place a couple that are acting up...
  7. Meelyn, can you please list all the batteries you've tried and the results you got. I think people will want to know what does not work as well as what does.
  8. Hey everyone, I am Meelyn Pandit, a PhD Student in the Bridge Lab at OU. We have been getting many questions on what batteries to use with the latest version of the ETAG reader. I previously used these 5V lithium polymer battery packs that are used for charging cellphones: Anker 6700 mAh battery pack This will give you less than a day of power though. Larger batteries such as this 10000 maAh model or this 20000 maH model will give you a few days (2-3 and 5-6 days respectively). I have used these batteries in my bluebird research and they work well, but they require exchanging the batteries every few days to avoid losing data. Unfortunately, you cannot attach a solar panel to this battery setup because of the voltage regulator inside the battery case which prevents the battery from being charged by the solar panel and powering the ETAG reader. The best option for powering the ETAG reader in the field would be to use lead acid battery with a down voltage regulator (lead acid batteries are usually rated for 12V, but if you down regulate the voltage to 5V then it will multiply the amp hours by 2, more or less). You will need to waterproof the battery and the regulator using a plastic or metal case. Hope this information helps! If you have any questions on powering the ETAG reader or any general questions about using or coding the reader feel free to email me at meelyn.pandit@ou.edu. Kind regards, Meelyn Pandit
  9. Thanks, Eli. It is the FAT-16 format that I missed. I will keep trying alternatives~appreciate the helpful tips.
  10. Dear Alec, The RFID reader will only work with FAT-16 formatted SD cards. The 64GB card is almost certainly FAT-32, and so the RFID reader won't work with it. I know less about what is compatible with iPads. Obviously your mac is compatible with fat16 which will allow it to read smallish SD cards. It could very well be that the iPad will not read Fat16 and that's all there is to it. You could test this idea by taking one of the 2GB cards and reformatting to FAT32 (use disk utility on your mac). If the IPad comms with the reformatted card, then there's your answer. Of course that card will no longer work with the RFID reader. It might be that the lightening interface device is not FAT16 compatible, but I doubt it. You could test that by plugging it into your mac with the FAT16 card attached.
  11. So I have been using pretty inexpensive 2GB SD cards made by "Transcend." They work great in the Gen2 RFID Reader board, and are easily read by the SD slot on my Mac. But when I go to try to connect them to my iPad (using this little lightning-SD interface gem), it turns out the card doesn't appear to have any data. When I use the card in my SD slot on my Mac Powerbook, no problem - data are all there. So then I tried using a different SD card (64GB SanDisk Extreme Pro) which is easily read by the iPad and the IMEEK interface adapter. I know this because I can see photos that are stored on the SD card. But when I take the SD card and put it into the Gen2 RFID reader, and test it out, nothing gets written to this card. Upshot: One card can't be written to by the Gen2 RFID Reader, but can be read by my iPad. The other type of card can be written to by the Gen2 RFID Reader, but cannot be read by the iPad. Wondering if anyone has advice on a type of card - or a formatting - for a card that will solve this incompatibility?
