3D Printed Power Transformer – Testing Magnetic Iron PLA by lasersaber | Jul 9, 2015 | Joule Ringer | 5 comments Filament Link: http://seemecnc.com/collections/filament/proto-pasta Link to the 3D printed parts: http://www.thingiverse.com/thing:918583 5 Comments Travis on July 28, 2015 at 12:38 am Have you tried it with the led filiments. They are rated 50 to 60 volts at 15 miliamps. They are 140 lumins. I would like to seen one of those light with a 9v cell jould ringer or joul thief. I think it may be great if it worked. I found them on amazon.com. I had ordered one I may try it with a jould thief circuit to see if it lights here in a few weeks when it arrives. Reply travis on August 16, 2015 at 10:33 am I grouned it to a 100F cap and it lit off a plasma globe driver. I burned it out when I ran the negative of the cap to a ground. I think a joul ringer or looper may be best for led filaments. Reply Michael on August 19, 2015 at 11:19 pm Hi, looking at your experiments, I thought you might be interested in capturing the fly back EMF from an electric motor and recycling the power over and over. It can be done by controlling the magnetic flux. You should take a quick look at Paul Babbcock and Jim Murrays work with electric motors! Reply Ben on January 27, 2016 at 2:24 pm Hi Laserhacker, Firstly, thank you for willingly sharing your knowledge and thank you so much for all the awesome projects that you’ve posted on your website. I stumbled across your projects accidently whilst on Youtube and instantly got inspired to learn all about electronics, with the end goal that one day I could develop my very own Super Joule Ringer, Super Joule Ringer 2.0 or even the Super Joule Ringer 3.0. I initially thought of buying the books that you have advertised in your website but I though they may be too advanced for me, since I know nothing about Electronics, Schematic Drawings, the use of Electronic Components & their function and not to mention the measuring of Watts/Volts/Amps/Ohms. Please would you kindly point me in the right direction as to where I can get started? Perhaps there are some books that I could get, sites I could visit or forums I could read. Your assistance would be greatly appreciated. Ben. Reply Andrew on September 16, 2016 at 6:58 pm Man love the work and research you’ve completed and currently working on. I’m in beginning stages of areas you’ve already been involved with for years. My interests are graphene, GO, ATMOSPHERIC, CRYSTAL CELLS, SOLAR, AND TOROID/FERRITE CORE. I need your help in identifying the materials or components that make up the two very large powerful magnets I salvaged 20years ago in vocational electronics class. They come from large main frames from IBM plant that shut down here a long time ago. I’ve looked for info on them and asked several blogs/communities with no success. Here is the link from my posting in Google community. https://plus.google.com/116967390217775047304/posts/ib2gQsU4f9e This link and thanks in advance for any help you might offer.
