This reply is off topic for this thread, but I can't choose where you chose to make your post, only reply to it. So in the interests of this not going off the rails, this is the only post I'm going to make in this thread in reply to your post.
$3500. For just one. And I have many. I'm not using $150 Creality's.
Quoted from Jaytech10:What other stuff did you do with it to sell? Does your fan system have a thermostat on the coil so it knows when to trun on and off the fans
Tried using thermostat switches in a number of ways, but it's an unreliable choice for coils (JJP's GnR magnet uses one and it's ALWAYS breaking because the switch sticks after a very short life, or perhaps the magnetic field affects the mechanism). Since the MTBF on the high quality fans I use are like 7 years at 24/7 usage, and most home users don't have them on all the time (even at 50% on like yours, that's 14 years), I shifted to the goal of just making them as quiet as possible (yes, quiet matters, even in a pin. Many customers have many pins. 6dB too much x 10 machines is a lot of extra noise in a quiet room). The new ZEN kits are essentially silent.
Quoted from Jaytech10:I have 4 JJPs and 4 spike 2s machines and 4 others. Even if I did just the bottom 2 flippers over 2k is not a good investment for me.
I test most new pins for temps and use that data to publish coil peak temp charts for many machines here on pinside. I usually also publish the 90 or 120 minute graph of coil temps for each machine I finish testing on. Not all machines NEED active cooling as my charts show. I don't keep it a secret which ones you can save your money on by leaving stock. My goal is not to sell Tibetan Breeze kits for every machine, whether it needs it or not, it's to help people know which machines DO need it and provide a plug and play solution. This is obvious to maybe everyone else and you missed that? Also, on games like JJP and the PROC-based ones, whether or not you're a trap player will heavily dictate how hot your coils get, so there's some personal input needed in the equation. Trap doesn't matter on Sterns because of their magic microsecond duty cycle ability. Defensive flipping will heat coils on all pins faster.
Quoted from Jaytech10: You shouldn't charge more or less for different manufacturers practically the same materials.
Well, I charge more or less based on the time and cost for the contents of each kit. For example, the Lebowski ZEN kit needs a special harness made just for it that is very low run (due to potential sales). While I financially support many pinball causes and sponsor pin tournaments to the tune of thousands of dollars a year, I myself am not a charity.
Quoted from Jaytech10:People on here are bad at math and creative skills good for you for taking advantage of them.
Seems like you're dissing everyone who's not really, really smart and resourceful like you, and therefore so dumb they open their wallet to any mod. Was that intentional?
The fact is, there's an exchange made. I'm terrible at car repair. Can I do an oil change myself? Yes. Do I think the oil change place is expensive for such a simple operation? Yes. But do I still go to the oil change place to handle that? Yes. Or what about a ring job to stop a car that's burning oil from spewing smoking exhaust? That's dirt cheap to do yourself, practically all labor. And it's a VERY expensive repair to have a shop do as a result. But, would I ever attempt that? Nope. Wouldn't know where to start. I don't have the skill set or time for it. So I'd pay someone with the skill and experience to do it.
You're into pinball DIY, that's great. Me too. I've posted PLENTY of useful pinball DIY projects on pinside here anyone can do for just the parts cost and their time, as a matter of fact. But there are plenty of people good at OTHER things besides DIY that would rather just buy a reliable plug and play kit with a long warranty and be done with it. So I make that available. And if you think I'm just farting out any old thing, I spent over a YEAR with various design prototypes and testing to make the new Tibetan Breeze ZEN kits. I started in Summer 2021 to make the next gen coil cooling kit. Thought I'd be done in 3 months. Took more than 12 more to get a product I was happy with that was truly next-gen. Some of the early tests were a spectacular failure because of the trial and error required. But the end result is fantastic.
"Taking advantage" is your opinion that ignores a lot of considerations specific to this, but it is by no means a fact. I've learned a LOT about coils and coil timing and duty cycles and fan construction differences and vibration that has been integrated in the Tibetan Breeze products as I iterate and improve them constantly. Most people aren't down to take that journey, they just want the result. And that's why I have a product they can just buy and be done installing in 15 minutes.
Quoted from Jaytech10:I made me 1 set for dialed in 3 flippers for under $40 usb plugged in to the service plug with brick.
I would never go that route. Ever. Plugging into the service outlet with a power brick is a very kludge-y way of doing it. But that's YOUR DIY project on YOUR machine. You made it work and saved some money. That's what DIY is all about. My goal is always to keep moving towards an easy-to-install, clean factory-look product. Using the service outlet or a power brick is a design fail - in MY OPINION. But you have a different standard, and though I would never do it, that's fine FOR YOU. My new ZEN kits for flipper coil cooling are the latest step in a clean factory-look design, and they DO look like they totally belong, with some improvements to actual function outside of cooling as well. But if someone doesn't want the ultimate, but they still want plug and play, I still have the prior version less-expensive kits available. If I was really as money-hungry as you imply, I would discontinue the cheaper ones and force everyone into the ZEN kits.
Are you sure? Because it feels like you have some towards me or my customers that you allege are apparently simpletons just begging to be taken advantage of.
Hopefully I cleared up your misconceptions about my equipment, process, goals, and continuing knowledge/financial support of the pinball community. There's a world outside your personal experience, where people would rather buy a plug and play item that works great than spend time and frustration learning to DIY one themselves. Yes, that world is out there. I deal with it every day.
