Not sure how frequented this forum still is. But I could use a haned looking for antennas for the keyduino and elechouse boards. One has to have a long enough lead to reach around from front door to the front for nfc door lock. Any ideas?
DIY door lock.
I've had 2 projects in the burners and working them mentally the whole time, Now i could use a hand in finishing them.
First one is as DIY door lock. At it's inception it was going to be all individual components. But then I bought this from Sparkfun:
It's the Lockitron box without the microcontroller. The assembly includes the mechanisms to physically turn a lock, the motor, the housing, and the means to secure it all to a deadbolt.
My problem getting started is the construction and placement of an nfc sensor on the outside of the door. There is a metal plate around the door that may be used to hide an antenna wire. It may b easiest to do it wirelessly. Not sure of best way to do that, I have some Z wave boards, or could do a direct bluetooth connection. J ust found some rf boards that might work.
One the big question for you giys is whatmaterial to us to place the antenna in to get a good read. It will be in a cold enviroment, It's obviously just the face that i ask about. where the antenna will read codes. any ideas guys?
Incorrect shipping on the NFC store
@johnyma22 I really wanted to take advantage of the spring sale. Especially after missing the window to use my cf voucher. The site gives a link to go through the US site for better shipping costs. That link seems to just route back to the EU site. I did notice the "ref us" tag on the sites address bar, so I continued hoping it would give the US shipping. This was not the case. It still used EU shipping prices. The price was something around £9 +change. Thought this was a mistake and so I started again. Same this time except the shipping went up to £13 plus change. I really wanted to get the 2016 to go with 2 ongoing projects of mine, but wanted to make sure I didn't pay took much. I'm just now at the end of the sale able to get some extra cash together to get one. Also, are the rings going out now of the second production run? Thanks.
RE: Why contactless cards are safe
@maz_net_au That article quoted by @Nephiel was about a specific technology in Germany. But even if a reader were compromised you don't actually send you bank numbers through. Just a one time use number for one transaction. Only the bank itself can translate that number in no your actual account number. No cloning, no reusing. That should keep the electronic theft numbers low. Using a Pin should also help keep the consequences of physical left low.
Congrats! (& questions)
Well done @MrStein! It's really exciting to see a project like the Keyduino in the forums go from your first prototype to backed project. Too bad it may missed the stretch goal. :( Will the antennas your going to offer be of your design? In my project planning I have a couple questions. I plan on using nfc in my car. Do you have an idea of the temperature tolerances for the boards and for the antenna? Is distance of the antenna lead a factor? If I use it as a door lock system, the antenna at least, and perhaps the board, will be closer to the exterior of the vehicle. I saw the one @johnyma22 uses. How does it hold up for you @johnyma22, and does it get very cold where you are? You wouldn't know it by the weather we've had lately (71f compared to the usual 31f at this time of year.) But it can get extremely nasty in the winter. Last year we had 9. 5 feet of snow by this time in the region. So cold will be a factor. There is a body panel on the trailing riser of my window I would use for the antenna to get a good signal.
Thanks again for sparking my imagination. My project ideas have most to do with replacing car and house keys as the nerve damage in my hands has made dealing with and using keys a PITA. ;)
RE: Carbon Fiber vouchers Kickstarter update
That's good to hear. It was smart to only offer a certain number of static designs this time around. Must have saved you a heap of trouble and time. About missing the expiry date on the voucher, I saw a similar post on another thread. I believe I should email support about that?
