Previous Post - Wireless Power - Eagle Library Hi All, Another update of my progression. It is important that I have fully read the datasheets for the Wireless products but I have found an issue although not major may require some modifica...
Transmitter Design: This week I want to write a little about the design of the transmitter. There is a ton of information on the TI website on how to design the transmitter: http://www.ti.com/lit/ug/sluuap8a/sluuap8a.pdf (Referen...
As I discussed in my initial posts, I have planned some surprises along my design. This is modification no1. I had mentioned that I will be using to at least try to use all TI Parts hence this is my change towards my goal. Instead of using XBee radio...
Hello Everyone! I just got my license of eagle working and for starters i thought i would generate a simple breakout board for the supercaps that i intend to use. In my free time i have been using my KNK Zing (a small CNC cutter) and experimenti...
For the past couple of weeks, I have been working on the case and the server aspect of the design. I made some videos but they are just too big to upload on my connection so will do something about them and might have them up on the blog by the weeke...

This weeks post will be about my receiver board design. I already published the schematic a few weeks ago, as I wanted to make it available as soon as possible, just in case someone else could use it. But now I want to elaborate a little bit on the d...
it has been a busy couple weeks. I have been getting parts in and discovering a few more parts that I could use (ie etchant and extra PCB). If you read my last blog post Shaky hands and precision soldering do not mix you will know that the...

For prototyping purposes i was hoping to try my hand at soldering some leads to a super-cap charger from TI. Unfortunately the package is a 16VQFN and my feeble attempt at tacking leads onto these 0.2MM pitch pads did not end well. I think the photo ...
For this week I have been preparing a post focusing a little bit on how all these wireless power devices work. It’s not my intention to explain the theory, it’s more like taking a closer look at some of the signals, try to reproduce some figures from...
My development kit arrived last week. I plugged it in and was immediately greeted with the red LEDs indicating power transfer. Awesome! Thus begins the development process- Step 1: Charge a Battery My sub is going to run a motor, a few serv...
Hi!I am sorry about not blogging for a while now. But I have to confess, I do not have much of an update now either. The Wireless Charging Kit is stuck at customs, so I have spent the last few weeks trying to wrestle it out. I still do not have an es...
