Not gonna lie, the third person thing is a bit weird.
Wow, can you open a time portal doorway? I'm not joking .

do you use like an active CAD to see the workings of the electronics. You might find one of those hole punches better to remove the pins you know the type on a wheel making holes in belts they are bevelled on the inside would squash the pin and push it out if they fit tho the hole might be to big
I can vouch for Mr Carlson's patreon electronics course. There's so much more on there than UA-cam, and it doesn't cost much either. A worthy investment.
I was totally blown away that anyone in this day and age would bother to take the time to make their own PCB. You can get a PCB with solder mask & silk screen in that size for $2.50. Why even bother doing it yourself.
Incredible. He says he will teach you one thing, and then proceeds to teach 10 or 12 things. Thank you Mr. Carlson, you are a treasure!
Very generous man is our Paul.
Teaching us 1 thing that consists of many
He actually takes us through his thought process and that understanding how every component will "behave in real life" is key to long term success.
Yeah. He is like that.
Nothing wrong extra knowledge.👍👍
Hey Mr Carlson! I am a certified MESA/Boogie and Fender amp technician and I ALWAYS learn something from your videos. You do such a nice job teaching, your videos are always clear, non-threatening for 'younger techs' and most importantly you do absolute quality/attractive work and always with a positive attitude. I can't tell you how much of a breath of fresh air your videos are in a world of negativity. Cheers from Michigan
Thanks for your kind feedback Sean!
Imagine buying some lab kit one day, taking it home, opening it up and seeing a board with the CARLSON mark on it.
Treasure!
I cant believe that PCB was home made !!! OMG that was so pro !
I made my first board using a Radio Shack CB Etching kit when I was 13, cira 1973. You just skipped over the hardest part, accurately drilling all those tiny holes! I didn't have a drimmel kit back then so I had to do it with a big 5 pound electric drill.
P.S. Don't spill ANY etching solution on your mom's formica countertops! :(
Level of detail, quality and the calm tone of Mr. Carlson speech, makes my anxiety level go down!! You're one of the bests!!! 👍👍👍👍
It's at times like these I'm very thankful for the low cost PCB's you can get these days. I don't miss etching PCB's at home at all, leave it to the pro's, send the gerbers off and get a professional PCB's in a matter of days.
Bogdon over at Hacksmith blew my mind the other day doing that. Also, nice build on his laser LED power supply.
An uA723, WOW! ...I was in school (70's) when the chip was already around for years. Like the NE555 & uA741, it is one of several legends that are still around! :):):)
Am really enjoying your videos! Formerly an I.C. Designer at EXAR. Ended my career in Silicon Valley at age 32 - I retired from Analog Devices, where I was overseeing International. :)
EXAR was a great company, and is very missed! The XR2206 (and many other IC"s) were fantastic. Thanks for your comment Robert!
I used those Exar chips in my Dynamic Expander Noise Reduction circuit as voltage controlled frequency modulated oscillators back in 1984.
@@MrCarlsonsLab = the XR2206 was one of many for which I created the micro-lithographic masks. The original design engineer is a Japanese-born gent by the name of, Yoshiji Kurahashi (now retired and living in southern CA.) He was my boss from 1974 to 1981.
Just saw the final "product" . jesus, he's a artist
Great: you are a 21st century miniaturist! Your videos, even the longest ones, are much more enjoyable than any TV channel!
Glad you like them, thanks for your kind comment!
Very well done Paul. Although my program is old and crude (Tube Pad) I have been making hand drawn circuit boards for many years. I still have one of those Radio Shack etchant kits from the 70's that has never been opened lol. Thanks for sharing.
You have incredible patience. Thank you for taking so much time to explain what you are doing in detail!
I like this guy so much detail ,and knowledge ,who has time to show you how.
Thank you for this video! I learnt so much about just etching itself! You're an amazing craftsman!
We did this differently - way back in to 80's.
We designed the layouts with tape and dots on plastic film back then. We used double-sided precoated resist board. First expose one side in the blacklight box, this created an image on the resist that was clear enough to align with. We'd drill through the location points then use them to align and expose the reverse side. Rinse the exposed resist off with caustic.
We'd then wet one side with ferric chloride and float the board on the etch. Rinse, flip, repeat. Clean resist with caustic soda. Drill the board.
Created DS processor boards like this - I did a few Z80 projects this way.
Did you remember to paste a copy of the NEW schematic inside the top of the lid for a potential far future owner to have half a chance of repairing it again? Hmmmmm?
Who else was picturing a particular Dan Akroyd sketch about a chef from oh so long ago? (I'm not trying to offend, it was a very amusing memory, and I truly adore Mr. C's pursuit of perfection.)
I actually do that with all of my builds now. I remember seeing all sorts of older gear when I was a kid with schematics on the inside.
Really nice looking PSU boards. Its interesting seeing old gear redesigned with SMD parts and old style through hole caps.
Very nice job! Glad it was in HD, too, Paul!
Beautifully constructed!
Very interesting. I have made single sided circuit boards before but not a double sided or even heard of liquid tin before. Very informative and educational. Thank you Mr. Carlson.
That board looked amazing. So clean.
Normally not picky about pronunciation, but the difference between silicon and silicone is very important. One is a semiconducting element, the other is the complex polymer PDMS, or polydimethylsiloxane typically. Silicon valley is in Northern California, and Silicone valley is in Southern California, with a branch in Las Vegas.
One goes on the board, the other goes in the boob. Don't mix them up, unless your a fembot.
Those boards are beautiful, I'm truly amazed at how good your work is, it's always top notch. Even the filming quality is amazing.
Thank you very much!
Thanks... this came out soo well. I was hoping you would release a seperate vid for the PCB last week, and I did not get disappointed.
Your videos are very interesting, I’m studying EE since a few years so I know a lot of the mathematics and theory (and have been repairing electronics for a few years), but I’m just starting to design and build my own PCBs. Your knowledge and practical experience is amazing, often you take shortcuts where new EEs would calculate stuff for quite some time.
Wow! Nice work. I used to do this back in the 1970's. All I had was an etch-resist pen. Nice to see Ferric Chloride is still used. My hand drawn circuits were crude but effective for the simple projects I did.
Bought a printed circuit maker kit from Radio Shack 40 years ago. It had a large plastic tank which doubled as a case to hold the equipment and the
Ferrous Chloride bottle. Funny how I actually forgotten ( when I was seventeen ) what I made but had to do with a model train diesel horn.
The kit had very precise black self adhesive tabs for making pads for IC legs (used a LM555 timer IC )which after etching was off a little on two of eight places!
I did the etch-resist pen ("Dalo"-brand) thing in elementary school back in the 80:s and did some still in the 2007 or something like that when building guitar pedals. Works just great for through hole components where great precision or fine lines are not needed. I still have the big pickle jar of ferric chloride somewhere, I've not used it for over a decade though so might as well get rid of it.
I bought the RS etching kit and would use the resist pen and reverse dead bug the components so I didn't need to drill holes
I use a sharpie marker pen as an etch resist ,works a treat!
Same here. In my high school electronics class (1971) we made our own boards using fingernail polish to cover the hand drawn circuits. We were building 12 volt variable DC power supplies. They actually worked when all was said and done. 8-) Pretty weak in terms of amps.
Watching you complete these PCB's reminds me of the company I used to work for. The bottleneck was ordering and receiving the boards in a timely fashion. It got so bad that they decided to buy a close by PCB manufacturer. The process was the same only on a much bigger scale. Positives were produced in the photographer's dept. and 'shot' on the raw boards, developed and plated in rather large tanks hung in the solutions and then processed. A design change could be turned around in a couple of days instead of a couple weeks. Big difference. A simple change could scrap a whole trashcan full of old boards. Typical government expenses and over runs, plenty of over runs. Good job Paul!
I use to make my own PCBs but stopped when I found an online service that allowed me to get 2 to 6 layer boards with solder mask and silk screen for less than I had in material and time (time is money after all) to process my own. I've ordered everywhere from 1 to 2000 boards through this service depending on the project and the quality has always been top notch.
And who would this be, if you're at liberty to say?
@@stevethepocket Download KiCAD, design your board and you can send the Gerber files to virtually any place that makes PCBs
I use Diptrace for artwork and schematics. Cheap (actually free for small boards) and it outputs all the data a fab house needs. I find Bay Area Circuits is a good source for small board quantities. I have no financial ties to either of these.
I first built boards in the 60's by manual taping the artwork, getting a negative made, exposing the board coated with Kodak Photo Resist, and then etching with ferric chloride (that part hasn't changed!) Now, I'd rather let someone else deal with the chemicals plus the boards come back conformal coating which is hard to do at home.
Mr Carlsson is one of very few and even less on youtube who actually knows how to appropiate bend wires on wired resistors, capacitors and inductors. This knowledge has obviously been forgotten or neglected when surface mounted components arrived. My hat off to you for educating how things really should be soldered on PCB.
Amazed by the method you used make PCB. I never thought it would be possible to do at home. I noticed in your videos sometimes you do get side tracked from topic, thus making the videos longer. It's your style of presenting and as a subscriber, I found them as bonus knowledge. Thanks for sharing.
Another interesting process.
Thank you for sharing your work and dedication.
Great job and thank you! 🙌 I was considering re-watching your earlier circuit board video anyway, and this one complements your other circuit board video very well. Great explanations! I was afraid to ask about the glassware, and you even explained that.
Just last night I was searching your channel for "PCB", saw the previous tutorial you'd made, thought to myself _"Ahh, I've seen that one"_ ... you are a legend, Paul.
Nicely done! I moved from toner transfer to photosensitive boards to get tighter tolerances, but it is a little more complicated.
And, just signed up for your Patreon channel.
very very nice home pcb diy video. i made pcbs in the 70s in a small lab, so this is interesting to see a different version to get the working results 🙂thanks
I admire your patience, Mr Carlson. Exelent job.
Thanks for going through the whole process of making a printed circuit board. I have not made one in years so my process is more of an antique process than the one you are using. As always great video Paul and explanation.
I was looking forward to a video from you, and here it is.
Excellent! This video gave a ‘blast-from-the-past’ as back in the late 1980’s to early 1990’s, I used the toner-transfer method, using a clothes iron, then vinegar and water for removing the paper, along with finger rubbing for the course, then a brush for the finer paper fuzz removal. The thinner the paper as tracing paper, the easier for removing. Ferric Chloride enchant and yes it stains everything and open fumes will corrode nearby medal tools when warm, if not sealed up. I never used the tinning solution but tinned manually with solder soaked desoldering braid and it was not an easy job as the chemical way. Wonderful video Mr Carlson, it surely brought back pleasant old memories. Also, a fish tank air bubblier helps with etching agitation if doing lots of boards. Additionally, Muriatic-Acid and Hydrogen-Peroxide is said to be a decedent enchant but I’ve only used it once when was out of Ferric Chloride and yes, it did work, only taking longer to etch but gave a good ending result.
I love content like this as I watch how other people do things so can pick up tips & tricks (like the nylon screw offsets -nifty!) and add them to my own work.
Beautiful work sir!
When you pulled out the can of Nevr-dull, I had flashbacks to my military days. I was in a ceremonial troop with lots of brass and lots of polish and Nevr-dull was never out of reach.
Great product and thank you for your service.
That was a great video, had no idea how much work went into making a simple board.
Really high quality video and your explanation is clear and easy to understand!
You are one of the best on YT in your branch! Amazing skill!
Very beautiful work ❤️👍
Thank you Sir, you are an inspiration and a very good teacher.
Thanks for your kind comment Wim!
Fantastic video! I have some vintage HP supplies I need to rebuild at some point, saved them from the dumpster.
Nice 👍 I plan on making a new idle circuit board for my miller legend welder. It still operates just fine but no longer idles down after a few seconds. I took a look at the board a while back and it had a burnt trace and a shorted cap. Repaired the board and it worked for a while longer. It's time to get rid of the twin thyristor setup and a redesign with newer style components now that it has failed again.
Using the board as a heat sink for a smaller component is an excellent idea. Very cool!
Thanks Michael!
Amazing project. I remember using photo resist and uv light in high school for my electronics projects in developing pcb. You are very informative. Amazing electronics knowledge. A great treasure you are......
Excellent video and commentary once again, Thank you for the content.
Mr Carlson you are the best. Anytime I want to bring my skills to a new level, I watch one of your videos. Thanks a million
You are very welcome Cody!
I've done this and it's quite fun... twas a learning experience for sure, but all in all, once completed, the device worked as advertised.
Mr Carlson is the best.
that liquid tin demonstration was amazing.
Thanks for showing us the proccess. I am going to be making my first PCB soon for a Neon rlaxation ocilatoer Neon Flower light.
Great Job Paul! Always enjoy your videos and how you explain everything very clearly. Have you ever tried the acetone method of toner transfer? I saw a few videos on that technique and it seems it works well at least for small boards. It is the same concept except the toner is transferred using an acetone rubbing process (cold no heat). No heat press or laminator is needed.
Mr Carlson you are the best teacher
Thanks!
This is one of the few channels that I thumbs up the video before even watching...
I love your workshop
Thanks for the info. I knew about electroless plating. But I did not know about tin plating for PC boards
Excellent work as usual Mr. Carlson!
Great work. Thank you.
Absolutely Amazing ! I must have played 3:10 - 3:11 at least ten times !
Carlson, you should do a video on how to get good video sound/volume/quality/etc. Even Leno's Garage can't get it right. UA-cam creators need a class on gain staging, compression,, etc and your input would add serious value. :)
Yeah, you can quickly be absorbed and totally forget about the highly detailed audio levels and video editing we have here.
Most UA-camr's are tone-deaf and most viewers watch on phones. smh
If you watch videos on a phone, that's on you. But bad audio seems to be normal these days. It's so easy to overcome, too.
Watching in Feb 2021 and was just thinking, Mr Carlson sound is sooooo good and here's the comment.
I'm so glad I joined your Patreon! So far just at the lower level but soo many more tips - fixen to watch your videos on parts to stock up on.
Damn clever idea with the Nylon screws. I never thought of that myself.
After watching this, I can't wait to try it! And to use it to build some of your inventions!
I just found out you can make ferric chloride and liquid tin at home quite easily and I want to try and see how that goes too!
Thanks for the video Paul. Very educational, very entertaining.
Glad you enjoyed it!
Not only do I value the abundant education, as well I'm appreciative of the good audio and video quality. Especially the audio. It is so important to have good audio! Thanks Mr. C! By the way, my nickname is Mr. C so that's why I said that.
Plated thru holes would be the holy grail of diy pcb making.
Fascinating! I would have loved to see the surface mount soldering....
perfect work!
You are a genius in electronics i wish i had the knowledge that you have always love watching your videos
Beautiful.
After the previous video I was hoping you'd go into more detail about the printing & transfer, so thank you very much again.
Very neat job
Very interesting. Thanks for sharing
The artistry is strong in this one.
Ive been doing software since I was a kid. Somehow, im just now learning electronics...youtube kept suggesting MrCarlson...eventually I bit. Now, I watch them all the time. I dont have the depth of understanding to fully appreciate them yet. But hot damn, what quality content. It will only get better as my understanding and intuition grows.
Glad you're enjoying David!
If you print the laser toner onto either glossy magazine paper (cheap thin glossy ad magazines work great), or onto glossy inkjet paper, getting it to adhere to the metal is much less time sensitive, you can leave it for days no problem before laminating if you wish, and it comes off from the paper much more easily once you soak it in water. I've done this quite a few times etching plaques and they come out perfectly. Printing directly on copy paper is a bit of a hit and miss though, and the structure of the paper can impart in the toner and make it not stick as well to the metal. I have a video on this very process as well.
Tried this, and it works ok. The paper in this video was the result of "a lot" of research, and works much better than magazine paper. (at least the magazine paper I tried.) I prototype a lot. Thanks for sharing your experience.
@@MrCarlsonsLab different strokes for different folks I guess. I too prototype a lot 😄 Copy paper has never led to any great success for me. Ultimately whenever I used that I got bad adherence to the metal and had to do lots of touch-ups with a Sharpie to fill in where the toner didn't stick. Best all around result was glossy inkjet paper in the laser printer, but since that's a bit expensive glossy magazine paper is I'd say 90% as good. I guess the principle is that the less the toner adheres to the paper it's printed on the better it will stick to the metal 🙂 Have you tried the etching films which you expose with UV and then wash off the unexposed film? While a bit more finicky I know a lot of people making custom circuit boards who swear by it.
boys i love seeing 2 of my favorite youtubers talking i bet you 2 could come up with a hell of a collaboration
why would you try to tell paul how to do anything. he is the king you know never saw anyone that knows as much as this guy.took a look at your channel.............. lol
@@SwitchAndLever I believe he uses some kind of glossy photo paper, not copy paper. There is some paper specifically designed for the pcb transfer method, though I have not tried it personally. If it works well, it would be a reasonable cost depending on the volume and size of boards a person makes: www.amazon.com/Circuit-Board-Thermal-Transfer-Special/dp/B01CGRL2G0
I have a laser cutter at home, which I have used it to do circuit boards by spray painting the board with an even coating of black paint, then using the laser to burn away everything except the traces. This method works, but can be finicky depending on paint, residue, cleaning method, etc.
I have also purchased some 'Photosensitive Dry Film' for PCB production from eBay that I intend to try, not sure if you've seen that stuff but it seems like an interesting method. Basically it lets you apply a photo-resist film to any board.
I am still experimenting to see which method I like best, I expect I will settle on whichever provides the best work vs results vs cost ratio. :P
Perfect job!
I have done this several times. I would add a step. Run board through laminator 2 times to get it hot before attempting the transfer. Then put your print on it and run it through 10x. This way the toner transfers on the first pass through and holds things in place. It kind of sticks the print to the board. Otherwise it doesn't do that on the first pass. And you can have misalignment problems. Or broken prints. I also printed labels to put on my laminator so I would remember the important steps in the future.
Lovely work!
If the Apocalypse comes, I want to be living next door to Mr. Carlson.
Oh man this is huge! I didn't think I would find a video on this! Really great!
Glad you liked it!
@@MrCarlsonsLab pretty hard subject to find something on. Next up designing a board to fix a problem Yamaha has in the RX V1 flagship.
You are incredible ❤
Best audio on UA-cam!
not sure there are others that are also quite good and well here you can hear the little clicky sounds when the small moist layer between the tongue and the mouth separates while speaking. if that is a quality sign or not is up to you i found it a bit irritating in the first half of the video so maybe a bit of a highcut does the trick
Perfect!
723 is an excellent choice, used them many times in many power supply projects
I think Mr. Carlson channels the spirit of Tom Swift sometimes! Thanks for another informative and interesting video! 👍
Fun fact: TASER is an acronym for Thomas A Swift's Electric Rifle.
Great video. Nice details. Was expecting to see soldering work. Your voice reminds me of Matthew George Frewer when he did SyFy Taken series. Thumbs up.
My main hobby is not electronics (though electronics does show up often), it's scale modeling. But scale modeling involves photo etched metal parts for extra-fine detail that can't be done in plastic. Making my own parts has been kind of a mystery to me, especially since all the modeling videos on the subject I've seen have been multi-step processes using lots of chemicals. I didn't really see this as a viable DIY thing for me until this video popped into my YT feed! This will work perfectly to make double-sided parts!! Thank you for making this video!
Nice video Mr C. I never thought of raising the board in the solution like that. I make only single side boards from time to time. While double side would be cool, I never thought of doing it that way. I just used jumper wires across the top. Thanks you for the Tips.
I use the muriatic acid (I use it to clean my drains) and peroxide method while heating the solution in a pan of hot water as well. Never occurred to me to use a glass pan like that... Nice! I use a old tupperware bowl...
Thank you for the video!
LLAP
You're very welcome Bruce!
Very nice board!
this reminds me my dad in 80s sitting on chair in front of bench and making diy transistor based radio receiver, because in my country under russian occupation these things were incredible expensive to buy them from shop. this is a way when people used to make diy c boards at home. after dad finished making board was time for soldering. unforgetable smell of hard flux, i dont know why but i loved that smell ;p btw beautiful c board;p
When I did DS boards years (40) ago, we'd use UV sensitive resist coated board, expose the design by blacklight tubes (actually the old dot/tape on clear film!) on one side. You could see the changed coating where exposed, drill alignment holes, align the second side, expose then develop both in NaOH, wash then etch.
Thank you Sir!
