Connecting a different load to the Wireless Power Kit

Image
Connecting another load to the W ireless Power Kit its pretty straight forward, as simple as to solder two cables. In this case I tried another LED module, but this with higher power specifications.  In order to connect this load first of all we need to find the following pads labeled VOUT and GND , this pads and pins are capable of provide 10v @1A - in other words 10W output power. Connecting another load This way we have the specified power output described above, now lets mesure the Voltage and Current: Voltage reading of 10.02 volts of 10 volts specified.  Current capabilities of 1.1 Amps (10W) So this kit by it self its capable of recharging a two cell battery without a problem and very fast also. We could charge a two cell battery of 1000mAh rated 1C for charge within just 1 hour, that sounds good enough for our application. Now that we now the power output capabilities we can select our battery and battery charger for our Feeding Baby Bottle Warmer. In the next post i will s

Wurth Electronics & ROHM's Wireless Power Kit  Lets begin describing what is in this kit and what is it for, this kit is a practical to begin and to understand how Wireless Power works, this kit contains: - Wireless Power Transmitter - Wireless Power Receiver - LED Load Module - Power adapter So this is the Transmitter: This is the receiver with the LED load module attached: With this two modules we can already do wireless power of 15W and connected to any device that accepts a voltage around 10 volts connected to the receiver module. Lets see them in action! It really looks pretty amazing don't you think!? Next week i will post how to connect another load to this KIT in a fast and a simple way before we get to start the design accordingly with our needs. For more detail information on how this kit works I leave you the following links below: http://www.we-online.de/web/en/passive_components_custom... http://www.rohm.com/web/eu/news-detail?news-title... http://www.rohm.com/

Off the clock design challenge project introduction.

A week ago I received an email of  Wurth Electronics  telling me that i was selected to participate in the OFF THE CLOCK DESIGN CHALLENGE , this challenge consist in creating a product using their Wireless Charging KIT, this challenge will be 12 weeks challenge in which I will be posting all my decisions and updates of my project, to read more about this challenge click here . What is my project for OCDC (Off the clock design challenge)? - It's a Portable Baby Bottle Warmer ( PBBW ) What does a PBBW is used for? why a PBBW ? Let me explain the idea of this project. A lot of parents are in constant movement, at work, to meetings, etc. Today there is not much time to simple things like to warm up the baby feeding bottle, that kind of task will just take a few minutes, but do we really always have that time? or are we always in the right place at the right moment to accomplish that kind of task, the answer, no, not always. This is why I would like to start this project using the Wu
