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...

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/...

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 proje...

This past semester, I worked on an independent study/project where I explored the programming of the PIC32. I've provided the details in the following PDF document. The key takeaway I believe is: "This document presents sufficient background information on the project, and implementation specific details. The most important contribution this makes is adding the experiences and a full implementation of the project. For even more detail and a thorough understanding, it is recommended that this report be read along with the reference documents mentioned in Section 4.1." I plan on improving this, as well as exploring the option of programming other PICs this summer. A cursory look made me think that the PIC32 programming standard was more complicated than the PIC16's. I'll find out! All the project code and settings can be found here . This includes the PIC32 project, as well as the MATLAB code for the programmer software https://drive.google.com/open?id=0B4SoPFPRNziH...

Turn off the computer. 2. Connect the ac power adapter. 3. Turn on the computer. If the computer can be turned on, it means that either the battery pack or the ac power adapter is functional. 4. Insert a straightened paper clip into the emergency reset hole to reset the computer. If the computer is still powered on, it means that the ac power adapter is functional. 5. Turn off the computer. 6. Disconnect the ac power adapter and turn on the computer. If the computer can be turned on, it means that the battery pack is functional. If you suspect a power problem, see the appropriate one of the following power supply checkouts: “Checking the ac power adapter” “Checking...
