The Unique Led Earrings
Want to be the most dazzling queen in the party? An engineer named Bertho Stoltiens shared his shiny earrings Blinkring designed, The earrings have a diameter of about 31mm eardrop, the total number of 12 LED were set in a circle above. This concept of the earrings is based on standard Cr2032 button-type battery with a slightly larger circular printed circuit board (PCB), the operation of the LED parts required is a small circle on the board outside the battery.
Stoltiens came across a number of challenges when carrying out the design case，because he did not have to think a method of boosting the battery appearance, but also installing a switch, so that the wearer can easily operate. Clamp-like battery holder is made of a paperclip, Stoltiens said the very small arc on the battery holder can provide sufficient spring effect to make the battery and battery holder close bonding; other side of the circuit board is the user interface to switch , as which the paperclip structure was used, both sides seem very elegant shape.
Stoltiens said in his personal blog that the existing switching device will be used as the next version of the earring design. It is a very hard to build up the Switch light adopted now.

In addition to the challenges of the physical PCB architecture, Stoltiens also encountered some difficulties in chip programming; the Microchip's PIC12LF1552 microcontroller is used，which can not be programmed by Blinkring’s PICKit2 tools being used，the next step may be carried out by using PICKit2 Device Data File Editor . There is also a problem, PIC12LF1552 has no standard ISP head for programming.
Stoltiens thought a very simple solution that is five contacts were added on the back of the PCB and made a customized programming dock (dock), the earrings can be held when needing to be updated. The spacing is 100mi on the PCB pad (pad) , therefore by using the contacts on the vertoboard be used
