Well, it has everything I need: it’s not much bigger than a piece of candy, it’s extremely light, it runs on battery, it can output an unmodulated 13.56 MHz carrier wave with a decent amount of power, the field can be turned on and off, it can be controlled over BLE, and the firmware is open-source. It really has all the features I need right out of the box.
Check out its performances. Not too shabby for a sugar lump:
All it needs is an external antenna and some code from yours truly, to transmit messages from a cellphone.
As for the bracelet proper, I’m waiting for a batch of PCL plastic to start shaping that - hopefully nice-looking, but I wouldn’t be too hopeful, as I’m not a very artsy kind of person.
I’m not asking, because I also have one, I got my Chameleon Tiny Professional from Sneak Technology ( $80 for BLE $60 for non-BLE ) Good for the Asia Pacific area, and KSEC for Europe, I believe Lab401 are also in Europe, but personally I"m not a 401 fan… Go KSEC if you are in Europe
I carry mine in my bag with a Keysy ( HF - LF Bases Covered )
Cool, clever simple bit of kit.
I have no idea. But there’s a simple protocol in the firmware that I should be able to implement to talk to the thing over BLE. It connects already, it’s just that it won’t answer simple text commands because I have to encapsulate them in their custom frame format.
It’s a nice device but the BLE functionality that I need is completely undocumented, and it’s giving me a lot of trouble. I can connect to it and list its characteristics, but that’s as far as I’ve been able to go so far. I have no time to dive into the code of the Android app that serves as BLE “reference API” because of work, and so for the time being, the project is sadly put on hold.
