  1. I hear you guys! I'm glad to be able to put time into this again as well. Happy New Year!
  2. Another video, this one goes over the basic functionality of the machine. Not how to use it but more how it works on a high-level. I'll be making videos of each component/system and how they specifically work individually, this is more a walkthrough of how they all work together. (And don't worry, I'll get a microphone before making those videos.) Have a great weekend everyone!
  3. Video Update for 12-29-2017 (You can also view on YouTube for the full post.)
  4. I've really missed working on this project and I hope that soon others will be able to make use of it! I just wanted to post a couple updates here. ] I've got it hooked up to a decent chiller now. No more pond pump and the 5-gallon bucket with a small computer fan radiator. Although that worked quite well. I also set the whole thing up on a rolling metal cart from Sam's Club. This was perfect, lots of room on the bottom for the chiller, a small area for spare coils and a shallow top for the induction heater to sit. I'm now working on the firmware. "To Infi
  5. James, You were interested in using ferrite material to focus the induction heaters flux. This site shows the application of EMS for SolidWorks to model the magnetic flux density in the radial ferrite cores under an inductive cooking coil. There are other programs you can use to model various magnetic characteristics such as MATLAB https://www.emworks.com/blog/induction-heating/induction-heating-engineers-empower-chefs#comment-9491 Two amusing things about this site's post though, for one they plagiarized a screenshot from one of my youtube videos (the very first photo in the po
  6. You are very welcome my friend. Those videos were interesting. Here at 5:58 you can see the animation of how the ferrite material carries the lines of flux. That second video cool as well. It's intriguing how the ferrite material was incorporated into a sort of clay or foam that you can mold onto the coil, allowing you focus the flux on one side. It looked like it started to get hot and smoke in the end though, or maybe that was just smoke rising from the metal. Whether it's a permanent magnet or an induction heater coil. Any time you introduce a ferromagnetic metal (iron, ni
  7. Don't underestimate yourself. Some of times greatest minds were self-educated! You're doing a great job, just be safe, keep failing, and keep learning! You won't run into too many people on the streets who specifically "know about" induction heaters but that doesn't mean you can't confer with other like-minded people about electronics in general. The induction heater circuit overall is a very fundamental and beautiful thing really. It's like nature wanted it to exist! My email is on my Github page. Shoot me a message, I have a book I want to send you that will help. Yes, there is a
  8. I was never that, but a little insanity is great for the creative soul. Or vice versa...
  9. Bandwidth - I never really thought of it as a waste of bandwidth, I did leave out the photo. Even though the quoted text was directly before my post, I like to make sure the context of my writing is known. But I won't do that on your topic anymore. Also, the window has closed for me to edit it so only a mod can remove it now. I don't want to delete the post and resubmit it because then things would just be out of order. Maybe we take bandwidth for granted in this country sometimes! Mod addition: Since you are not aware, let me inform you that many of the over 150 countries we service ar
  10. Great job James! It looks like you have tackled most of the challenges you faced in the beginning, a significant step indeed! I see a few things I want to point out that helped me and hopefully, they will help you too. I am close to publishing all the info about the ReactorForge on GitHub and the website. But you have come a long way, and yours is the closest I've seen to what I built, so I wanted to share this much at least. I'll start with the mains input and work my way to the work coil. I'm sure it's just a test setup, maybe you had a variac hooked up in this photo, but de
  11. Hey all, I just wanted to get on and personally thank everyone on I Forge Iron for their patience, even if you had none which is totally ok! I have had a lot of changes personally some really good and some difficult. For the last 4 years, I've run my own business, raised teenagers, and have done way more traveling than I care to do. I never gave up on the open source high power induction heater, ReactorForge, but it had to be put to the side for a while. I'm still extremely busy but I am finding ways to manage my time that will allow me to be with my family more and work on this awesome p
  12. There are many differences that it makes, you have to weight a handful of variables to determine what is right for your application. ​There is a massive amount of current flowing in that coil therefor any resistance of the coil generates heat. Smaller size = greater resistance = more heat. With the smaller size comes a reduced coolant flow which also adds to the heat build up issue. Put simply you can go smaller if you can keep it cool. The smaller diameter allows for tighter/closer turns which can contribute to a more uniform heating of the work piece. The smaller diameter tube is easier to
  13. I'm trying respect the rules here and not to cross the line of promoting a product so there is a lot I'm not going into here, just answering questions. But yes we are shooting for well under $2K for a raw kit and a bit more for an ARU kit (almost ready to use). Basically an hour of your time, and a screw driver or allen wrench then your ready to go, no soldering or any complex assembly. All individual components and modules for the ARU kit are being QA certified in a working test bed. We are also exploring a kit assembly option and will be offering multiple warrantee levels. This machine is ov
  14. How many KW will these unit's be? - They will be marketed as a 15KW machine. That is in reference to the oscillating power in the tank circuit. It not a good rating system in my opinion but it's the one adopted by the industry (and many others). The actual input power in volt amps is about 7-8KW that's 208-240 volts @ 32-34 amps. See the two units below for reference, it doesn't mater if they are Chinese, Russian, or America, most all of them rate their machines like this. http://www.magtechina.com/products/234.htm http://www.acrossinternational.com/15KW-Mid-Frequency-Split-Induction-Heater
