Hi All,
Many thanks to Texas Instruments and Element 14 for inviting me to participate in this challenge. I hope I will not disappoint.
I've always been excited about wireless power and efficient ways to do it. I been busily swotting up on this subject and I was amazed at how much power that can be transferred efficiently with TI's wireless power products.
This challenge is to use these wireless products which comply to the QI standard with my everyday life.
I've already thought of quite a few standard ideas but to start I thought I'd start with something quirky - a Plasma Ball.
Sorry for the dark picture but here's the Wireless evaluation kit which consists of the TI transmitter manager bq500210EVM-689 receiver evaluation module bq51013AEVM-765 and a Plasma ball.
(I have yet to receive the Würth Elektronik charging coils, transmitter 24µH part # 760308101 and receiver 10µH part # 760308201.)
All I had to do to get this far was to connect the transmitter to a 19 volt 500mA current limited power supply and to make up a wiring harness for the plasma ball.
The plasma ball power input is 5 volts at 300ma so it was well within power specifications.
The two green dots are the Transmitter and Receiver LEDs.
I've experimented with changing the distance between the transmitter and receiver and playing with the plama ball to observe the effects to the power source variations.
When moving the receiver away from the transmitter, the source current increases until the transmitter no longer the receiver and the power is shut off.
This distance is about 10mm.
I have plans to construct several wireless power Transmitter prototypes distribute them across my house.
Likewise with the reciprocal receivers. These will be retrofitted into many household items in an attempt to improve them.
