Hello, any plans to upload the podcast to CZcams? I and I think many others mostly use CZcams for podcasts.
What resources did you use to learn to create your electronics prototypes? If you can teach a course yourself, that’ll be even better for us beginners just cause other people who talk about this stuff can be pretty unexciting / hard to follow.
The future is the gig economy and so education is a whole industry that would be serving tens, if not a hundred million people in the US alone. You can consider creating your own beginner, intermediate and advanced electronics prototyping courses for like Udemy or even sold through your own website. Since you already create content with your podcast, this education part of your business could be a real money maker, not to mention, really fun.
It only took you 4 years to get here and you build a whole company from the ground during a global Pandemic. Huge respect, really 🎉
"So what did you do recently?" - "I ran a Kickstarter for some LED Bowties and placing and soldering the components onto them SUCKED. So I built a pick'n place machine, ran a Kickstarter for that, started a company and now I can make hundred Bowties with 10th of the effort 🎉"
Try reacting to _that_ conversation. My brain would just go into "buffering mode" 💭 xD
@@BloodyMobileyeah it’s amazing! I know a musician who was extremely annoyed at having to carry his piano up and down stairs when doing a performance, so much that he now designs and produced tiny pianos 😂
I'm so excited for small scale manufacture, 3D printers, the Lumen, Levi Jassen's work on small scale PCB manufacture with plated vias, Christopher Helmke's work on automated part sorting, and collection. There's genuinely so much happening.
My thoughts on the reflow controller - If you think the problem has been solved for that cheaply, make a video about the oven that works well and focus on cooler and bigger stuff. Like new P&P functionality or bigger production or something.
Also since the oven is a mains powered device, it can be dangerous so you may find yourself in the safety certification rabbit hole for different markets, that have different laws. Sure, feel free to make it as a cool open source project if you enjoy making it, but i believe that it will take focus away from the P&P project and i'm not a huge fan of that, if there's already a good solution.
PS: At work we use the Reflow oven kit from Beta Layout that does what you are making and it does it pretty darn well for a good price. So i think that problem is kind of solved.
Here's a tip for you guys: I just found out about USB CDC -NCM. This created a network interface over USB with a computer. Meaning your embedded device can host a http server. Got it working on the RP2040 and ESP32-S3.
Cool stuff! Manual IP config or some fancy DHCP setup?
what's the one that's better than the t962a? (older brother?)
Right so whats this mythical reflow oven that just works right, out of the box, from the same company that makes the T962A?
That's around $400, I would very much like to know!
What a great "wrap up" style video - it's awesome to see how your workspace has grown and filled out. Looks like you might need to start looking for a bigger premises soon ;)
Thanks for all of the fun and entertaining videos this year - I really look forward to watching them when the YT bell chimes, and hope you'll continue to find time to make more in 2024.
Thanks for the tour Stephen! Agreed on reflow, congrats on so much progress this year you guys!
Great video. I developed a PnP machine 12 years ago. I used very simple ideas, but the most difficult problem I faced was pulling the clear film off of the tape (I used weights back then like on your wider tape). Your system is so much more advanced than what I cobbled up. I am happy to see this type of development is still going on even with the prices for full assembly are pretty cheap with the exception of low quantity runs. This type of project can also teach you so much, from the feeders, to the vacuum system and regulation, to the optical closed loop positional and rotational placements.
I think you have a great approach to decide what to work on. There is no use to work on stuff for the sake of it unless its a fun hobby project.
Solving things that aren't out there yet or improving things that do not work well at a certain price points, are the valuable targets to work on from a product perspective.
Love the Podcast! Much respect and admiration for you in your all success. It's been a blast watching you for the last few years. I hope that I can start a small business soon, inspried by you and Lucian.
Thank you for clearing your schedule for us!! Amazing video!!
You guys are such an inspiration.
Loving the podcast! Just finished the automation episode the other day, would love a video about your Notion setup, feels like something that may be I sightful. So happy to see Opulo doing well, would love to someday try out a Lumen!
Great work. The reflow control looks interesting.
Ive missed these! Great work as usual Stephen
Good to see the update Stephen, I've been following your content for a few years. Nice to see the PNP come full circle.
This was an amazingly informative video, thanks! :D
The Lumen PnP look so nice!
Way Kewl work creating a pick and place. YES to open hardware .Been following your videos on the creative process. As for the GlowTies - they're kewl too, though I think the diffusion cover makes the classy.
Nice work! Did similiar calculations for part of my EE degree, but insted calculating at what point the cost becomes better for the production. So i had a yearly production plan and was comparing between hiring people (avarage salary for my location) and giving them cheap soldering irons or hiring less people and buying those expensive panasonic pick-and-placers. There is quite a bit of litrature written on that subject.
I love your enthusiasm 👍
looking forward to that podcast :)
So glad to see you guys are doing well man! Can’t wait to stop bye some day and say HI :)
Is there a plan to do a video talking about the feeders in detail. I would love to see what changes you made for the final product
I hope I can one day have a project just can economically justify buying one of your machines. So good.
I would say keep up the work you have been doing to keep reducing your hands on time! Automate the stuff that you can so you can have more time for fun RnD stuff!
Can you recommend a stencil printer and how to use one effectively?
Super awesome, but curious what the unit cost of having these delivered fully assembled from the factory would be since you did ~100pc on the kickstarter
cant wait to have enough to buy one of these for my projects (an opullo i mean, not the glowtie, although the glow tie is cool)
Love what you guys are doing. Have you thought about injection moulding for some of those smaller 3D printed parts? Can be produced soooo much faster once setup and would free the 3D printer for other stuff.
Still love your stuf! Keep on the good work! And by the way: are the ties up for sale? I would be really interested in getting some! BR from Germany!
What's the old saying "Work smarter, not harder"! Well done guys, love your setup!
I program PIC micros and the hex file loads in about 2 seconds, so I just touch my programming cable to the board without a jig and hit go. I have played with arduino, but it seems HIDEOUSLY long to compile and program. Is there a hex file and quick programmer for arduino? By the way, what is your favorite solder paste?
Finally a new upload from you. I really miss your regular product development videos :)
I would like to know if your company is profitable and how good or bad the financial situation is.
Why the switch from Prusa Mini to Bambu P1P for the print farm?
What is the mod you guys dit to the hacko soldering helper with this printed part on it ?😀
Which stencil jig do you use shown around the 16 minute mark?
Nice update! Any recommendations for ~300mm x ~300mm reflow oven, cost effective, prefer to buy (T962A 1500W?), but open to hacking DIY controller onto NOT smart oven. Cheers!
Hey Stephen, I have one question about your PNP, can you tell me what speed it has? chip/h. PS: I love all your videos!
How long to apply solder paste ?
Where can I get that automatic screwdriver with feeder? that would save a lot of time for my startup
Thanks!
we actually had it custom-made for that screw! search "auto screw feeder" on alibaba and you should find some similar options!
Nice - how's sales going? How many have shipped out?
Thanks for sharing, why not upgrade the lumen with brushless server for speed in the x and y axis
Why don't you use a conveyor reflow oven like the T980? I'm thinking of buying something like this to complement my Lumen PNP, to speed up my process. If anyone here has one, any advice is welcome.
3:08 Can you explain it in detail ? why would some pins be shorter and taller ? Like what is the significance of it ? Is it that GND should be connected first or something of that sort ?
Man spent 4 years automating something that took him 40 hours. What a freakin legend
How reliable does it handle 0402? My current system is a Quad 4000C that is technically capable of 0201 but even 0402 is a crapshoot. The parts tend to bounce out of the feeders creating all sorts of problems. I have to watch every run from beginning to end unless I am running 0603 or bigger.
I love it, Stephen - a very appropriate circuit choice! BTW a step I don't recall seeing in your videos - what do you do to cleanly pop solder paste onto each PCB? PS have just subscribed to your podcast!
i actually had a whole section about this but i had to cut it because the vid ended up being 20 min long! we get framed stencils from PCBWay when we buy our boards, and we toss em in a stencil jig. I talk a bit about them here: www.opulo.io/blogs/how-to/setting-up-a-mid-scale-smt-line
@@stephen_hawes amazing, thanks. My board is incredibly simple in comparison (only 8 components and two of them are through-hole) but love learning more about your processes!
@@stephen_hawes Did you ever get the auto paste dispensing element of the Lumen working reliably?
Please make a playlist for your podcast
What about a conveyor belt that rolls the populated board from the pnp into a reflow oven and out the other end?
Very doable. Thats what I have at work.
whats the 3d printed device on the headphones?
How about a kit that has a thermocouple you put in the oven like the Bluetooth meat thermometers, and it cuts out the power to a smart socket thus “overriding” any conventional countertop oven.
I think the reflow would be worth the effort if the cost could be dropped under the $400 mark. Granted, I know there is the more diy way of modifying the toaster oven which seems to work very well and also you still have to have some sort of profit etc for it to be worth the time/effort.
Still would be very cool, but I'm interested to hear about your other ideas of what should be the "next step"!
Also thanks for another PnP video, not that many Lumen owners doing that (probably too busy using it)
What did you find to replace the T962A?
T937
Miss you ;) let’s have more videos
Downloading the new podcast now. This is terrific. Stephen, I am retired now from the government and am creating a new LLC for design and small scale manufacturing of specific security hardware and test devices. I plan to purchase the LumenPNP. How's the lead time to get one and 8mm and 12mm feeders?
that's rad! it's at 4 weeks right now, but we're making some good progress on bringing that down!
Could you share the improved T962A model/vendor with us? I need a reflow oven ASAP
T937 he mentioned it in the comments.
Thank you@@envisionelectronics
I can see the base reflow controller being used to control things other than a reflow oven. Like a heat treatment oven for example
Does heat treatment need a temperature profile? If not a dirt cheap PID control box would probably be optimal.
Well the reflow oven would still be interesting because you would make it a cheaper option, not reinventing the wheel, making it cheaper for us makers wich is great!
So what is the T962A's older brother?
oh duh, my bad! it's the T-937. we're still doing some tests with it but it's promising! a bit hard to get in the US though.
So it is the T-900 Series? We have to protect Sarah Connor at all cost 😤😎
@@draco5991rep since they are not coated in organic material I don't think we need to worry yet.
19:02 if there _is_ a solution out there that exactly solves your particular problem, then yeah, no point in re-reinventing the wheel. Just take the wheel.
I would personally skip the reflow project.
The reflow master is very nice as is (I only have the V1 and it is already quite nice, my oven is a bit underpowered for SAC solder but not the fault of the controller)
Need to expand my office...
Its been a while😂
hate to say, your safety specs have an amazing fit, but plastic looks thin on side
Skip the reflow oven project!!! You do not want the liability if any one of these catches on fire because of operator error. Even if you are not found liable, just the cost of defending and proving your innocence will do you in...
Are there plans to make the machine faster? That is currently the most biggest reason for me not to buy it.
I love to see you abandon the reflow project, because I'm working for a year and a half to ship an OS Reflow solution and I don't have as nearly as 20k subscribers as you do. But I still will try to sell it as a kit. So: Bad, bad Idea! Don't do it! Ever! As Elon said it: You have dug your own grave! You are gonna lose millions!
Jokes aside: There are Reflow solutions out there. And If you have anything to add to them - do it. It's time to make the gear better than ever. Commercial solutions already lack hobbiest features. A Ready-to-market product, which sturs up the industry is much needed!
You're the sole reason, why anybody is telling me "there no money to be made" is wrong. You started in the worst of times and still are going. Don't know, if you're going strong - but you're still around and making a living for several people. Keep up your great work. I will need one of your PnP machines in the near future!
Sooooooo does that mean glow ties are decreasing in price considering production labor costs have gone down? (Half kidding lol)
