If im remembering it correctly you switched to a larger motor in order to have enough power to drive both the tape peeling and tape movement with the same motor. Now that these functions are separated wouldnt it also be better to revert to the older smaller right angled motor in order to get a slimmer feeder design and therefore having more space for feeders on the machine. Also 32 feeders seems a bit small. Maybe adding a bit or 2 extra to the address would be beneficial to future proof the system for people who wanna expand on your project. It is after all open source. Anyways great design! I wasnt a fan of the mechanics of the last revision of the feeder but i really like this new design :)

It seems you have finally learned the third rule of soldering: Flux is magic! 1. More Heat 2. Less Solder 3. Flux is magic

@@XiCKwY 'More heat transmission, but less heat in component.' Exactly, you only need good heat at the surface of the component leads, heating the components to death like some things suggest is only a crutch against making cold solder joints. Learning to make good joints without putting crazy extra heat into the part is far better..

Congrats on the flux achievment-unlock! Glad you like it! Next ditch the pointy tip of your iron for one with a bezel. Having a flat area in the tip helps keep a little reservoir of solder there, which will help heaps with drag soldering. And if you bridge it, clean the bezel and surface tension will have all excess solder stick to to the iron instead of the bridge.

Finally!! I can't wait to see everything working

Thank you very much, Stephen!! This will definitely change the way we make boards as a DIY community! I can't wait to see the awesome projects that this machine will assembly!

The guy at pcb way will definitely ask himself why you still use no solder mask between the pins on your micro footprint.. At least I do;)

Holy moly, it's awesome how far your project has come. And your video quality is outstanding! Music and cuts and everything is on spot

I came for the pnp project I stayed for the happy peppy cheery boi

Love your channel, the pnp is coming along. Love to see some content specifically on board design and choosing components, at least your approach to it. Can't wait for your next vid.

this is incredible! also i really appreciate that you a keeping all the designs clean and dont just force sth together which will only last for the video! happy i found this channel:)

Your break was well used--this week's video quality is crazy awesome! Can't wait to see new grounds with the conveyor belt!

The end of the tunnel approaches and I am seeing the light! Great work Stephen and thanks to all the other contributors that are collaborating and pushing on all the aspects of these efforts. I listened in to the trailing edge of last weeks xoom session after work and suffice it to say we have a very talented bunch of individuals in what I'd characterize as a global consortium. I'm still stuck in limbo until I've moved, otherwise I would be actively building an index right now. "Cheers" to all those actively engaged in their builds, and keep engaging and sharing on the discord going forward.

You just made it in time. I almost went crazy from the wait lol. Happy new year and good luck on your projects!

I am impressed with your skills, the absence of flux was driving me nuts, great to see you have now implemented it.

Yes ! It always feels awesome when it blinks in the FIRST TRIAL !

Finally! Your videos are always so good.

Super cool. Once you get these really dialed in, I might have a fun torture test for your PNP. Next soldering upgrade, get a chisel tip. I can't solder anything with a conical tip!

love this projekt. i would never need it, but its fun watching you build it. keep up the good videos.

Good vibes, Lots of energy, Entertaining, Subscribed. EDIT: Also lots of valuable information you can apply to other projects, if you are able to follow along

Great video!

Nicely done! I'm liking the progress you've been making. One thing you might run into is RS485 really wants to run over a twisted pair, so you may have some signal integrity issues running over the parallel strand IDC cable you are using. You can get twisted pair IDC, cable for this, which has flat sections every so-often for crimping. Looking forward to the next installment!

Love the enthusiasm!

Congratulations for this incredible project, man! For the head crash, if it's now a problem, you could consider to change the camera and head position. For example, invert camera and head position alon x axis, or rotate it by 90°, so they're perpendicular as the the feeder axle. Hope to be clear :) Good job, man!! Waiting for next video!!

I love the excitement at positive results of ideas. I get a lot of those too.😎

Good old one-wire bus* *Minimum number of wires: Two.

awwwww this is so awesome, time to get some eeproms going, I may need to start aloner project just so i cen get into details like this level

When your boards are at their final revision, will you do a crowd supply? I'm in awe of all the work put into this

Another approach for the addressing could have been an addressing pin going from "feeder base" to feeder base, with a cheap AND gate in between. The addressing input goes to the AND gate and the feeder itself, and an additional output goes to the other input of the AND gate. The output of the AND gate goes to the addressing pin on the next feeder base. Via RS485 you can define a command that states "if you don't yet have an address and your addressing pin is high, take X as address". After a feeder receives an address, it simply switches the output to the AND gate high so that the next feeder can be addressed. In order to deal with "unoccupied" feeder bases, you can add a pull-up to the input of the AND gate on the base feeder base board. You can even feedback the output of the last base to the main board, so it immediately knows when it is done addressing and therefor how many feeders are present. Hope this makes any sense. It sounds cheaper than using an EEPROM to do this stuff and we've done something similar on an commercial HVAC system we've build parts for.

Respect! Good job

Hi Stephen, I must say this project has turned out really awesome, it was fun to follow and now I have gotten the confidence to start designing my pnp. If I can have a suggestion tho, I think a vibratory feeder design implementation would be useful too for this project. Keep it up!

The kicad files aren't in master - they are in the feeder-05 branch

I've basically just binged this entire project. When you were talking about using your own protocol I was wincing. So glad to see you shift to something a bit more standardised, not having to worry about maintaining that custom thing will make life way easier. Did you think about using the serial bus for address programming though? Keep one address (I'm a network gal, so I suggest going for the top address) as broadcast. Send out a broadcast 'I want to set an address to F6' message, have all the lights go blink blink, press a button on the feeder to select the one you want to program. Send a "I've been programmed with my address as F6' back to the host from the feeder you selected. Either have the other feeders watch for that message as well as the button press, or have the host send a broadcast releasing the others from their wait state.

Heck, you could program a sequence that way....

Wow! So proud of all the achievements you and the community are making! Who finally convinced you to use flux??

great Video. A quick word about solder paste if you use up the container quickly it's consistency should stay the same and it's great for dispensers. However I have personally found that it will eventually separate ( after about a month of being opened ) and even after stiring it, it will never be quite homogeneous again. This makes it's use in solder paste dispensers frustrating . I prefer and recommend solder paste stencils instead . It makes paste consistency much less of an issue. That said best of luck on your project.

Complimenti sei molto bravo, ottimo lavoro 👍

I was googling about 1-wire and found your new video 🤣

your making me get back into some electronics engineering

I think it would be really cool if you made a video or two going in depth with the code. I understand though that a lot of people would find it boring and you might not want to do it. Your videos are great keep it up!

Now I regret, that I've watched your latest episode.. no more episode to go, for now.. 🤐 Great stuff, very inspiring!

Oh wow dude..... Truly inspiring!!!! :D Sooooo Stinkin Coo!!!

Damn, maybe I gotta look into making one of these.... maybe sometime in the future. Looks hella fun and could make prototyping a breeze.

finally a new PnP video! i was start to enter PnP progress withdrawal

this is awesome

I feel like the crystals you are using have capacitors built in, and you're also adding them externally... AMAZING job on all this though BTW... I'm so impressed.

this man's laugh is infectious

Kudos for using FreeCAD and KiCAD bro!!!

I saw you taped the end of the peeled waste film onto the waste bobbin... why not model some kind of cut/slot/friction fit for it to grab that w/o tape?

awesome! just found your channel, also started building a simple PnP machine over christmas. Re. EEPROM, will the feeder itself also remember which parts it has in it? I guess that can be stored in the uC of the feeder?

im just porting this to this vid in the hope ull see this comment. i just watched the vid about the camera module. im not sure if the hotspot problem has been completey resolved yet. if not, i can give u a great tip that ive used with our vision projects. you can buy polarized film really cheaply online. if you put a polarizer over the camera and a different one over the LEDs it will completely block out any reflections!

Dude, new sub here. Are you a full time youtuber? i mean the stuff in creating Pick and Place machine is godly awesome. i mean i do have some engineering knowledge (worked as Tape and Reel Engineer for short time before becoming a developer) about this mechinism, creating one is really awesome. Wish i have the money and time CAD skills to do this.

You could have the feeders take a command from the serial interface that tells them what ID to write to the EEPROM. Then use the key combo to enter "programming mode" and send the ID from the computer. That would make the process much easier, considering you're gonna write custom software.

That is very cool

I hope the novelty of a PNP being assembled by hand for the world to watch isnt lost on you heathens.

Really nice project Stephen! Could use one of these to assemble all the PCBs I have in my animatronic project !! Found you through your MakerCast episode. Just started my KZread channel showcasing my animatronic and would like to get in touch with this community.

He's back. At last.

Love your channel. Please try stencil for your prototypes. It will be much much faster to assemble everything. As soldering oven you can use clothes iron that is upside down or pan filled with sand.

Why do you do SMD soldering with an iron rather than a heat gun+paste or a reflow oven?

Thanks for sharing, stephen what's the part number for Feeder spring connector?

You think you'd ever need to go above 32 feeders? Since you soft-limited the machine because of the binary programming mode with leds?

in my experience of running a PnP machines with designs that fit on a 35x35 square double sided PCB you'll need more than 32 feeders. an entire side of my machine is taken up with just passives (0,10,75,300,470,1k5,4k7,10k,100k,10nf,22nf,100nf,470nf,1uf,2.2uf,4.7uf,10uf,22uf,47uf,100uf is 20 feeders. then you need all the ICs, leds, didoes, connectors, inductors. i can't use a machine with less than 60 feeders with some additional tray spaces for parts that don't come on tape.

this guy needs more credit

Can you please tell me which theme for KiCAD Schematic is this? Thanks

this is a really cool system. but instead of using the feeder floor and 1 wire eeprom, just have the feeders stack with pogo pins, common the 12v, gnd and rs485 lines, and daisy-chain a uart with each feeder just passing the next its address+1 then you have each feeder remember which part it has and its width, then when ever you add or remove a feeder the stack can just resort its-self, complete with free support for any width feeders.

That PCB vise looks great, where did you get it from?

just a small idea, have you tried taping some string or ribbon to the foil that gets peeled off to reduce the amount of wasted parts when putting the foil onto the spool?

Wow, the same T-short Dave from EEVBLOG has. Good choice.

can you share a link where you get your spring finger interfaces ?

11:30 How does one go abouts creating a "programming flash sequence". Is there an atmega on that thing?

You got a new subscriber.. spicy video

Really cool project. I think you should try to make it a more narrow design. Resistors, capacitors, can easily eat 20 different feeders, if you are not careful with a circuit / PCB designs, and they are usually very small, a so bunch of more narrow feeders would really help waste less space. Not sure what is the limiting factor in your design, but it looks it might be the motor.

What a genius

Whatever happened to the sweet biotech Flame thrower arm...😕

Hello Stephen, Can you tell me how to program STM32F103xx? I don't know how to download feeder-firmware to the chip? thank you~

You can use a modbus broadcast command to program floor addresses. Should be easier to automate, just have the user move a single feeder across all slots.

Stephen Hawes, Have you thought about adding uart going to your motor drivers so you can utilize the features of the tmc2209 motor drivers in place of what looks like the a4988s? It would remove the need run ends tops due to "stall guard 2" plus, you wouldn't have to mess with the pot(can modify voltage in Marlin) and has the benefits of being nearly silent! May reduce your BOM and work! Just a thought Working on my own Pnp and you've prevented me from running into a few issues, Thank you!

I know it's quite late, but "ribbon cable connector" brought me to the answer. They are called IDC connector, they have their own category on LCSC for instance. :)

Please use BC2 soldering iron tip. It is thin enough for soldering microcircuits in a QFP package, high enough heat capacity for soldering elements in 1206 packages (it is very convenient to solder 0603 with such a iron tip)

Truly awesome once again. I hate to admit how lazy I am (or how much I don't like Patreon), but have you considered using KZread's "join" button and abilities to have subscriptions here.

First FreeCAD, now flux and IDC connectors, where's this going to end? I like it!

I was wondering if you have looked at PushPull feeder design? It looks much simpler and costs around a few bucks to make...If so, what are the pros and cons of using it?

I only just found your channel, and I'm quite frustrated that I only just found your channel.

Maybe this has been adressed but I can't seem to find anything about it: 1) What is the feature difference of this feeder design over the somewhat already popular and foss 0816 one? docs.mgrl.de/maschine:pickandplace:feeder:0816feeder 2) Isn't this one a lot wider meaning less of them can fit on a machine?

There is some guy's job is to look over your schematic.. to make sure that your tolerance is within spec of production and to place the cut lines and to place the board into a larger board for production.. the real boards are about 2'x4' in size.. you also have the film people that have to check the films for etching and cutters at the end.. along with the boxer's that pack up the products.. and the QA people too

whats the issue with fusion ?

You have to uodate some of those footprints to get silkscreen between some of the pins
