Not many are cancelling, but it is a long list, it grows daily, and people become frustrated that it isn’t moving more quickly. I am also frustrated at times that this process isn’t quicker. It’s hard to set appropriate expectations when you don’t know how long it will take to truly resolve an...

Hi all, :bang: I am sorry to report that I am still not past this MOSFET failure issue - which means, unfortunately, that it will continue to affect some of you. I am very sorry. :uhoh: The learning curve on this project has been steep at times. This has been one of those times...

Thanks for posting, @Rollingstoned ! I am glad it got there OK and thrilled it's working, and also not surprised that it's working better. I feel like I have delved pretty deep into this issue, and I learned some good stuff along the way, which is part of my motivation for doing this project - I...

Yeah, but I'm a one man band. I have been responding to critical emails throughout this most recent development process, and I have been giving priority to existing customers with heaters that need repair. If you are one of those and I missed your email, please email me again ASAP and I will...

Hi all, OK. I have the right fix now - no, really! :D - and can finally close the book on this MOSFET and diode failure stuff. The higher voltage diodes are working very work. I will be using them in both repairs and new heaters. Huzzah! :rockon: Repairs: If you sent your heater to me for...

Hi all, Quick update: The TVS diodes continue to perform well, and I haven’t had any failures in the current voltage range. That’s great! I have the SMD parts I need for building new heaters, but I am still waiting on the right “through hole” TVS diodes to arrive to repair existing heaters...

Hey @RushVaporTrails , Please send me an email and I'll look it up*. You are in my waiting list database by your email address. But the short answer is you are probably in a similar spot as you were back then, because I lost a lot of ground in March and April. I had to slow waaaay down on new...

Thanks, @Terpenetime ! Trust me, the March 28 version of this would have come back to me for repair, anyway . :rolleyes: The version on my bench at the moment looks pretty fucking good. It's been completely stable so far. Still waiting on more TVS diodes for comparison testing, but the current...

Hi all, I promised I'd post an update after some more testing, so I just want to share that the higher voltage TVS diodes continue to function as expected, both on the scope and IRL. I haven't been able to break either the diodes or the heater yet, and not for lack of trying. I have been...

Hi all, Back with more exciting Flux Deluxe TVS Diode Updates. :wave: Today's Special: 24V TVS Diode Oscilloscope Graphs! Good news, folks - the higher voltage TVS diodes look like winners so far! To save time I didn't circle stuff in the graphs below as I did yesterday before, so I'll...

:brow: OK, I did some thinking, and I have a theory about why things worked as well as they did at first but have since stopped: It worked when the battery pack was depleted, and failed when those batteries had had time to rebuild their charge. To make a long story short, I still think I have...

Thanks guys. Unfortunately, I'm seeing failures now after the initial success I posted above. There's more work to do on this, unfortunately...:science: :popcorn:

Hi all, Some good news - the TVS diodes got here, and they seem to work! And well! Will need to see how they hold up, of course, but they work exactly as they are supposed to in their primary role as voltage suppressors. Have a look. Test bed for these measurements is a Flux Deluxe with a 15mm...

Thanks again for your support, @pxl_jockey , @Obsessed 2 , @lookhigh , and everyone else who has been following the project and is interested in seeing where this thing goes. Your support makes it a lot easier to absorb the frustrations that come with this sort of endeavor. :tup: Update on the...

Thanks, @ClearBlueLou . It's similar to debugging code in many ways, but it takes longer because new stuff needs to physically come to me before I can test it in the circuit. =-=-=-=-=-=-=-= First things first: If you have a heater that fails, please contact me, and we will discuss next steps...

Hi everyone, Sorry for not posting sooner this week. Flux Deluxe: Unfortunately, I learned this week that several recent Flux Deluxes failed soon after their new owners received them. :\ :(...:goon: It isn't the MOSFETs this time, but, ironically, the diodes I added to protect the MOSFETs...

Hi all, Happy 4.20! I have several Fluxer updates to share. :D New batch: I started a new batch of heaters yesterday, and sent "please confirm your build options" emails to the first 25 names I know will be in this batch. Do not despair if you are close to my current cutoff date (added to...

Thank you so much for posting that, @HersheyStainz ! I really appreciate you taking the time to write that up, and I know the folks who are patiently waiting appreciate it as well! :clap: Here's some closure/post-script to last weekend's Reflow Solder Oven project: It ROCKS! :rockon...

Thanks, @maxvapor710 - yes, I ordered a couple of the aluminum trays from the ebay seller as recommended. I did not go with the convection model as the info on Whizoo.com suggested the convection fan was primarily used for add'l and faster cooling, and I can live w/out that at this time. I was...

Hi everyone, My project this weekend has been building this reflow soldering oven, the one I mentioned last week. It's been a fun build so far, and it looks like it will be a few more hours later today to wrap up. A few in-progress shots: When it's done, I'll be able to solder batches...
