Thank you Brad, always hated the noisy aquarium pumps, would drive me crazy :-) Glad I could be of help. Take care.

@@iHayri1 I wonder do you smell any oil from the fridge compressor?

@@mrechbreger Actually, you can smell a little of the oil but it is very minimal and if you put the compressor into an enclosure it would be hard to smell anything.

​@@iHayri1 I thought about using it too until the point that I read that those are non oilfree compressors. So I spent 100 bucks to get a oilfree compressor (it's for sure louder than the fridge compressor but it's still acceptable in the apartment). We're using a vacuum generator and the colour of the damping module has changed to a slightly oilish style.. I don't want to make the inside dirtier than needed.

@@mrechbreger It sure has oil in it but you can catch it so to speak with one of those cheap foam filters that you stick on the output pipe. Input being the vacuum in this case. This is more of a poor poor mans compressor, you can buy them as cheap as 5 bucks, I paid $2.50. lol, can't beat that :-) You know, you just brought me to an idea, I should put my air quality monitor next to it when running and see how much pollution I get. Worst case I could put a small tube connected to the output pipe out the window :-)

Thank you Adam, most of the time I even order items double from different vendors, just to be sure that at least one arrives in a timely manner :-) Now I need to finish your temp cubes and send everything out, the OLEDiCADE's are jumping around in the box and are eager to be played :-)

:-)

Thanks Jon, believe me I am very eager to finish the PNP and have it do the work for me :-) will definitely make more videos along the way.

You are very welcome.

Thank you so much, yes they are just push pull, held by a small bearing in a rubber seal. Simple but functional.

I am sure there are, worst case you can use these and put a piece of silicon tube over the tip

Hi Johan, they did not get lost, I just can't keep up with all the requests I am getting. Due to too many projects I have going on and I'm behind, I will not be able to make anything custom for a while, sorry.

Hayri ok it's fine, got other parts of the vehicle to work on. I'll maybe contact you later on in the future. Keep up the nice work 👍

Thank you for your understanding :-)

I have tested the solenoid with several thousand cycles with no problems whatsoever. The changer is just a mechanical part and can be used indefinitely, don't think that the neodymium magnets wear out :-)

@@iHayri1 Two questions for you: 1. is this the solenoid? www.banggood.com/12V-DC-2-position-3-way-Small-Mini-Electric-Solenoid-Valve-for-Gas-AirPump-p-1057895.html?rmmds=search&cur_warehouse=CN 2. Does that adapter that mounts on the motor allow for auto-change? Can you show me an auto-change cycle? I don't see how that is able to do autochange... thanks for your time

Thank you. Interesting video you have about your factory, nice to see some steps involved to produce the PCB's and all the machines.

Thanks for your words. I have watched some of your project videos. If there is any need to visit our website - www.wellpcb.com. We also welcome your comments or suggestions to our website.

I did check out your website, seems like the standart ordering page these days. www.PCBWay.com is very similar. I do like the additional PCB colors you have.

There is no extra charge for the color of solder mask and silk screen. Hope we can have a chance to cooperate. I believe you must be impressed by our quality.

It"s just next to impossible to try out all Fab houses, especially because I am getting my PCB's for free, actually in exchange for KZfaq video reviews.

Please feel free to copy or take inspiration from my design, no problem. Glad if my videos will help other people :-)

@@iHayri1 Awesome, thanks dude!

The gcode will be exported from Eagle and used with either LitePlacer software or OpenPNP

Hayri but still. You have to tell the code where and what for components and tip changes. Guess I need to look at Eagle maybe to understand. :-) Looking forward to seeing this running.

Eagle just tell the PNP where the parts are located with coordinates, then you tell the PNP, when you set it up where you placed the parts on the table and the machine then picks up the component and places the part. Of course there is more involved in this like nozzle change for various parts and so on. You need to tell the machine in the setup which nozzle too use for which parts. Just check OpenPNP software and you will get your answers.

Wrong, guess you did not watch the video, there is absolutely no noise coming out of the valve and since I am using a fridge compressor you can hardly hear that either. But most people use the aquarium pumps that are annoyingly loud, those make sound, not the valve I am using.

Hayri well not that too noisy but still can hear clank clank.. I've seen ur video and it seem used same solenoid like I used.. kzfaq.info/get/bejne/gsWPobOc1M_Gl2w.html

Nope, mine are way quieter :-) My phone was like 3cm from the solenoid and the switch from the battery holder is louder than the solenoid. Maybe you are using yours with a higher voltage, also your vacuum pump can be heard. Once I have my compressor in a enclosure and underneath the table it will be whisper quiet :-) What software are you using on your PNP, is it OpenPNP ?

Yes it was openpnp using ramps 1.4 board.. I'm using 12 volt from d9 and d10 to run a pair nc valve, no valve and vacuum pump and let 1 blow pump keep running,will give a try on 6 volt using stepdown for valve maybe it will be quieter.. Thank's for the advise. :D

If you have the same solenoid as I do you can even power them directly from a 5V pin on the mega. How good does the mega with the ramps and OpenPNP work? I got some spare and could try it although I wanted to use the Liteplacer software.

Thanks, but sorry I do not have any part number, bought those on Aliexpress a long time ago.

@@iHayri1 No problem, thanks for the reply. Aliexpress has some nice stuff on there, but they won't ship here to the UK!

@@simonbaxter8001 No problem, why is Aliexpress not shipping to the UK anymore? I guess they used too, no? Is it because of Brexit? Maybe I can help.

I bought it from Aliexpress, just do a search for what you need.

The ones I use won't help you much unless you have the exact same design, if they are too big, they will stick to the nozzle, if they are too small, they will not hold it.

I don't quite understand what you mean.

@@iHayri1 i wanted to understand who many pieces there are. i found in this video kzfaq.info/get/bejne/iNNdlKyqu5-nm6M.html thank you for your reply

Hi Mike, haven't heard any issues like that till now, also my magnets do not really touch the Juki's plus I have seen similar designs where the magnet actually touches the nozzle holder while in rest position and no issues. But thanks for pointing it out, will keep it in mind.

Thanks for your input. Well, I do love my RGB lighted keyboard :-) but I am not a gamer although I love how it lights up at night where I do most of my work. On the other hand, I used to have underglow Neon lights on my car but that was 25 years ago, would I do it now? Hell no, I don't even listen to music in my car anymore, just want my piece and quiet while I listen to the car engine :-) For anybody that wants to know it, I have a Alfa Romeo with a boxer engine and that just sounds great. Not to mention that I have a 20 dollar radio in my car :-) I agree with it being a marketing buzz and sometimes less is more. Thanks if you read it this far.

Sorry, I do not work with LCD displays anymore, still have plenty collecting dust, and I just don't have the time to take on any custom work, been too busy with my own, still unfinished projects.

Yan Bourgeois Man, I hope that you got plenty of money, because you're asking for months of dedicated work and some hundreds, maybe some thousand in parts... Custom LCDs and hack proprietary communication protocols can be a hell.

But do not use flame on Juki nozzles - those have plastic-rubber tips!

Thanks for the link. Btw, I had my nozzles on the holder for a long time and they did not magnetize. As I mentioned earlier mine do not touch the nozzle. Also the smaller nozzles do seem to be made out of metal only the bigger one for chips has a rubber ring and that can not be magnetized even if you wanted anyway :-) There are also a lot of fake Juki holders out there, so it might be different from the original ones.
