Hello, My buddy and I thought it would be cool to make a wirelessly chargeable night light for my son and are stuck at this point. In order to finish our little project we are just looking to develop a way to wirelessly charge a LIR2450. On the receiver, we have about 1.5" diameter to work with for the coils. Is there an off-the-shelf transmitter we can use? If not, what is the transmitter circuit. Can this work with an off-the-shelf AC/DC converter? We also need the transmitter to go into standby when not charging. What is the receive circuit? Maybe this is a quick answer and a "quick buck" for someone. As this is a fun project, we don't have a big budget so ridiculous offers will be ignored. :) If you don't have any answers but can point us in the right direction, that would be helpful as well. Thanks, Jared
