KeyDuino, Arduino NFC (PN532+ATMEGA 32U4) by MrStein
-
Excellent !
@MrStein Ok je vois, je vais attendre encore un peu alors :)
Tiens nous au courant, c'est vraiment super ce que tu fais!
Bonne année :D -
After some long days of eagle conception, 3th version is done !
What is new?-> physical USB for the keyduino nano (stronger).
-> only one atmega 32u4 for the classic version (previously a atmega32u4 + a atmega328) that's really cheapper.
-> re-design of the board, silkscreen of the nano one was unclear.And, last new, I bought an old oscilloscope for modify the nfc antenna!
and after a lot of antenna design and according circuit calculation:
-> better antenna and according circuit, that improve the reading distance of a badge by 1cm and of the nfc ring by 0.5cm (usefull if you use a box between the antenna ant the nfc ring) :)
I start a conception of 6 prototypes (3 nanos and 3 classics) now the only thing I can do is waiting and search for small batch production in china :)
-
Super :)
Des nouvelles quand au fait de rendre open source ou de le vendre? -
Alors pour l'avancement du projet c'est toujour un peu compliqué administrativement parlant, mais maintenant que les designs hardware sont terminé on va pouvoir avancer ;)
De toute facon le crowfunding doit être validé avant la fun d'année comme c'est mon projet de fin d'études, mais le plus tôt sera le mieux. (C'est déjà long à ce mettre en place ^^)Sinon là je crée des librairies pour simplifier l'utilisation et je termine le développement de certaines shields ;)

First picture from china:
Normal one:
As you can see, there are 2 buzzer pad in more for identification application :)
Nano one:
I really like the black PCB with white silkscreen :D
For the nano one, the connector is maybe a little bit too big, btw it will be a male connector instead of a female one. -
These are seriously sweet! Much prefer the black/white over the blue or red boards. They look way cooler.

A quick realisation of a NFC drawer unlock with a KeyDuino normal;

-
Here is the tutorial, somebody can tell me if there is some english mistakes ? thanks :)
-
Awesome videos!
-
FWIW thanks to @mrstein I have some of his boards and I can say they are amazing. I was up and running in less than a minute from opening the package..
I'm excited to support his project and get it live!
-
Video not available :(.
-
Sorry, the video was updated, here is the available one ;)
-
@MrStein That's a great instructional video, dude. very cool!
-
@MrStein - How are the board designs going? Excited to see iteration!
-
@LoganFive we were supposed to meet on Monday to go through it, progress is good. The boards are pretty much ready to go into production but we have to figure out a launch strategy / campaign! Perhaps if you can make some content to help our launch we can send you a prototype board?
-
@johnyma22 - I would love to work on some kind of content. What kind of launch and content are you thinking of?
-
I would also be interested to work on it.
PS: Je suis en France aussi si ça peut aider
-
@Nairod785 @LoganFive Just stuff like user videos, tutorials, pictures.. Nothing pro level, just stuff average folks like us can relate to. You think you can do that?
-
Any help will be welcome :)
Curently I have made some sketch for keyduino to smartphone project ( I will send you asap John but currenlty I'm on holiday).
We also search someone able t
o make a librairy for the keyduino, there are a lot of lib for the pn532 in HSU but have a custom lib will be easier to use :)
If somebody is able to do that, please contact us :) -
@johnyma22 I would really like to do that. Let me know what points you would like covered in it. I have some ideas already.
