Small scale Wireless power Transmittion

Former Member
Former Member over 11 years ago

I am still fairly new to all this kind of work compared to many of you out there. Though I have a fairly simple goal that I hope to expand upon later on.

But I am hoping that some of you on here would be able to help me with this;

     My goal is to make a version of the Blue lantern ring from the Green Lantern expanded universe, building the mold its self is simple and making the majority of the

     interior component circuitry is not as complex as it could be except for one component. I wish to put a rechargeable battery inside the ring on the bottom and include a

     power receiver for power to be transmitted to the device when charging the battery is a 24,5mm rechargeable CR2450 outputting 3.6v at 110mAh. I wish to power somewhere between 1 and three      0603 smd blue LED's that take 3v at 20mA. The goal is to make the transmitter inside the Lantern its self (in the show they touch the ring to it to charge it) but my goal is being able to put it      inside and have it charge without contact. and yet still have the receiver small enough to fit on my finger within the ring its self and yet still produce enough voltage and current to charge the      battery, the transmitter circuit can be much larger than the receiver as the lantern its self is not that small there is a little give and take for the ring size as well. not a huge amount but a little bit      still. The main goal is to make it so that I dont have to keep changing the battery and giving a purpose for the lantern its self!

 

     I do a lot of volunteer work through Scouts Canada in their medical program.We (as highschool students and above) provide medical services at events around our community, for youth in the      program and public events around our province  Majority of it is dealing with children and they seem to like our other stuff IE; batman logo on some of our stuff, reflective strips on objects and      such. The odd superhero comics we have around it just helps them understand we are there to help. I would really appreciate it if someone here could help me design a circuit for it so that it      would be practical and yet still functional. I would really appreciate the help and I know the kids would love to see something like that at our next event!

     Thank you for taking the time to read this and if you have any input please please let me know! any changes or recommendations welcome!

    Can't help you with making science fiction come true  - sorry.

    Charging batteries takes time - so you would need to hold the receiver up against the transmitter for an hour or so - might as well arrange to plug it in and everything gets simple.

     

    (You have put the same post in two groups with different names within a minute of each other- that's very bad form - post once and wait to see what happens, otherwise you fill up the forum with noise and no-one will love you image

    my apologies for the confusion the charge can take as long as it needs to for it to charge. The end goal is to make it so that it wont need any metallic connections on the outside and can be completely contained inside a plastic shell. I know the average charge time is approximately 3 hours for the battery in question and that is fine but I just want to be able to put it inside and not have to worry about if the connections are made or not.

    This is an idea and not tested !!!!!!

     

    If you wind some turns inside the ring (so the ring is a coil encased in wire) and then place that over an ferromagnetic post in the charger (and even better close the magnetic circuit with a hinged bar) then a coil on the post will be quite well coupled to the coil in the ring.

    Probably the cheapest way to make the magnetic post is re-purpose the core of an olde iron cored transformer by sawing it up. You'll need to wind your own coils - and do experiments to sort out how best to drive them.

    Thank you, I am taking anything, theory, idea, concept anything that has any merit to make this viable device. This is an idea that I will be attempting hopefully soon. I will post any progress on a blog post with pictures of the outcome I hope!
