Last days until the exhibition: Putting the prototype together

During the last days we made the bracelet for the wrist and incorporated the rFlea and battery in the design by using handicraft and soldering. We sewed small pockets for both and fastened them with velcro on the back of the bracelet.

Left: rFlea that is connected to the battery and the NeoPixel ring. Middle: Gluing the velcro on the leather bracelet. Right: Bracelet and the two rings (in blue leather for bracelet A and B) with the leather bands for hiding the wires.

 
It is worthwhile to mention that we made two bracelets with corresponding tech (bracelet A and bracelet B) since we wanted to show the communication and interaction in the game to a full extent. Sadly, the RFID-reader on bracelet B stopped working before the exhibition, leaving us with only bracelet A that could read the RFID-tags placed on the other participant. The cellphone still worked though and could send the data a reading from the RFID-reader on bracelet A gave to both bracelets and displaying the corresponding Happy Points on each NeoPixel ring. 

As stated before we wanted to connect the rFlea on the bracelet with the RFID-reader on the ring to make it all work. We hid the wires with leather bands going from the bracelet up to the ring on the finger and the NeoPixel ring, that would show the amount of Happy Points gained, was placed on the bracelet instead of the ring. By placing the NeoPixel ring on the bracelet it was easier to carry for the user than if having it on the ring.

During the last days before the exhibition when we tried everything together we found a problem, we had previously tested and noticed that the RFID-reader could read the tag even if we had our hand inbetween them but now it couldn't read through the leather in the ring. We revised the design and placed the RFID-reader on the back of the bracelet making our bracelet/ring-jewellery into a simple bracelet. It both looked better and worked fine now. The prototype was ready for the exhibition!
