I love Collin's Mannerisms and personality. Makes me feel welcomed.
Couldn't have said it better, Yogi.
Isaac Asimov reincarnated :D
Thanks for doing this, Collin. A coworker recommended I check this process out instead of soldering onto prototype boards, and this video has me excited to do it. You make it look much easier -- and fun -- than I expected. Rock on!
I came here again just to give a thumbs up...
nicely done , highly professional indeed..
+Blenson Paul hey ,if anyone else wants to learn about introduction to electronics pdf try Elumpa Circuits Expert Alchemist (do a search on google ) ? Ive heard some extraordinary things about it and my mate got amazing success with it.
this guy is my spirit animal
Aren't humans animals too? :q
actually there is a big debate about it so right now it is an opinion for now though
+ko animations There is no debate.
@@crashthestash Well, I've asked my parrot to etch my pcb and so far he's just shit on it with a lot of squawking
i made my first one today
Just watched this with my 9 year old son and we were both inspired! So cool! We are going to give it a go! Thanks my man, we loved this; beautifully explained with passion, care and simplicity. Many thanks for sharing! My son wants to give you this; 👍 Great work Colin! You have two new fans....
So far I've enjoyed all the video's that I have viewed on this channel. I also am one of those that is almost petrified by the thought of making my own circuit boards. Thanks for giving me the inspiration too give it a try.
Your laid back approach is AWESOME. Your not stressed and simple direct explanation is just what newbies need. Your system is exactly how I make my boards and mine come out excellent every time. I skimp and use ferric chloride hexahydrate and caustic soda but I have been doing it for years and know the measurements. Also an etch tank with a fish tank bubbler and heater bring the etch time to under 8 minutes depending on copper thickness. Dry Film Solder mask is cheap and easy with a laminator.
This is a very interesting piece. Thanks for posting this. I was always wondering how I can bypass the hassle of making my own but you seriously simplified the whole process. Thank you.
...and I thought it was some really drawn out process to do this! You made it look easy...thank you!
Excellent summary of one layer PWB etching! We are having a lab this week and had multiple lectures about this, along with extensive instructions, but this video really connected the dots. Thank you :)
You are awesome! Look at the perfectly centered blueprint. Highly developed sense of art. Also, I like that you cut the unnecessary frames off getting to the point without wasting time. One of the best CZcamsrs.
I have no idea what I just watched. But there was some shiny board there at the end.
eddebrock are you a nincompoop? I hope not.
eddebrock great! thats the first step of learning
eddebrock
This is a homemade circuit board manufacturing process.. a board such as that's inside your own computer or PlayStation.
After having done making the board, one can 'solder' electronic components on it. You can make your own radio station or a satellite receiver or whatever you want.
😂😂😂😂😂
@@kardelsharpeye1380 whats a nincompoop?
this video really helped me thank you
you demonstrated great ! The precision, precaution and the way you showed off was brilliant. Thanks a lot.
and this... this is why I dropped out of college. I couldn't handle being baby sat without learning anyr... here, I just learned something new and awesome, and a dense amount of documentation online makes my days brighter and more knowledgeable.
in 2014 electre-engeniering school in Požega, Croatia we draw the whole pcb with a permanent marker lol
but it was some fun to do this in school :D
best way to learn!
Yes, I've done that in the old days. Time consuming. Could not do that for the connections of today. 2017
I am making one right now for a home made drone. Wish me luck
Emmanuel Essandah how did it go?
Send me pic .
Emmanuel Isanda any follow up?
@@dilbo_swaggins3957 Yeah he died... Drone to the face
anything?
The world needs to see Collin more often
Colin always makes the best stuff.
"(...) it's got heart! Something that those boards don't!"
Ahahahahah
You're the best!
: D
He's a subtle comedic genus, hehe
I always expose to sunlight on a sunny day. And it makes such a big difference! Why be stuck in a dark room with a light bulb when I can watch some birdies flying and look at the blue sky!
mendebil True my friend
UVs produced by sunlight aren't constant on the board, which means that you don't really know what the actual exposure time should be.
Sometimes it does not sun shine and need to practice when the sun doesn't shine.
bcz it is 100% homemade.
I followed this video, but instead of using a CFL bulb I used a halogen. I put the board after it in the developer, but it came out exactly as it was, like nothing happened. My board was sold as photosensitive, it came with the protective sticker, but never looked green or blue. Just copper color. Do you think only the lamp was the problem? After putting it into the developer I killed the photosensitive layer, right? So I cannot repeat it with a CFL and the same board? If I cannot: can I still use the board with marker / iron method? Thanks a lot in advance!
I'm sure I will never need this but the fact that it can be done at home is amazing. Kick ass!
That is the most bad ass video I've seen on the Make account in a while. Collin is awesome!
Please! Please! Please! Do more videos with Collin!
I have been making pcb s for years. I made a rocker for the solutions, uv light box and using a Dremel drill on a flex cable.
There are now new products and procedures that are really fascinating, I use a MacDraft Pro drawing program to create the positive circuit and print it out on an old hp 5000 printer to the transparency sheet. I like the idea of using two stacked prints to enhance the pattern. I sometimes use a heat lamp (150W lamp) over the etchant to warm it up. I made a vent hood with squirrel cage fan to blow fumes out. I am still experimenting with the photo resist sheets, (now on order) and using the hard to find photo resist in the spray can to try on my home made pcb spinner, that will be used in the hood. Sorry I went on here, but that about covers it. //... Joe
you look like mad scientist .. hehe keep up the good work ..... very educatational
I just did this process following this video, and using the same products from Jameco. It worked perfect, and I got a great board. The only difference I found was my board had to sit in the developing solution for almost 30 minutes,
I give this process a big thumbs up, it worked great.
10 years later, the music hasn’t aged very well, but still just as helpful. Thank you!
I've found that a laser engraver is fantastic for making custom pcb. Rather than having to rely on those light sensitive boards, simply paint the whole board black, print your circuit out with the laser engraver removing the unwanted paint i.e. the copper that is to be removed. Then continue with Ferric Chloride.
What type of black paint, if I may ask? Thank you.
how does a copper pcb work? since the whole copper plate is conductive how would you route with it? seems like everything would be joined
comming from a noob: i think that it might have some sortof insulator on the connecting parts
The whole plate is made of a special type of fiber glass which is an excellent insulator, it's coated with a thin layer of copper, the copper that is etched away leaves wire like connections glued to the fiber glass plate.
i thought it was obvious?
Awesome! I have been waiting my whole like to learn that, thank you.
aaron selby from what I've gathered :
The whole plate is originally one copper plate.
The design imprinted into the photoresist is a negative of the finished, desired design. The transparent parts of the pellicule are not the traces, they leave light pass to the photoresist,which dissapears, leaving the copper exposed to be eaten away by the etchant.
The parts of the pellicule that are left opaque are the traces. They block light, and the photoresist remains. That photoresist protects the copper from being eaten away from the etchant.
Love it! Quick, simple, and to the point. Thank you!
I liked this video a lot, put my mind at ease. The guy was your "quintessential electronics geek", but he was smart, and cool about the process. Highly recommend to my friends already. Thanks for the info!
4:47 I could smell the chemicals in my nose :) Does FeCl3 smell?
In my opinion, harmful etchants (like ferric choride) are un-nessisary to develop board. They require special disposal, are environmentally un-cool, and require special safety measures. I use white vinegar, salt, and hydrogen peroxide to etch boards. Results are always perfect. These chemicals are far more benign than methods suggested above.
thanks, totally works, and no special disposals
Except you are making Cupric Chloride which is harmful anyways... Also when you add salt, and see those fumes coming off? Thats Chlorine Gas.... A Chemical weapon. So be careful.
now there you go, you saved some and killed more including yourself
How long does it take to do that. Sounds interesting though. I don't know what the recipe for that.
Warren Brown, where is the chloride coming from in this approach? From the board itself?
"This board has got heart". Colin, you are the man. I love your uber geek style, great work man!!!!
Thanks so much!
I now believe you have to sacrifice hair line to make a quality video, excellent blend of score, lighting, information, scripting, and topic. Well played sir!
I swear I seen you in Alvin and The Chipmunks
06:10 sorry, but you forgot to tell the people, that if they get it in their eyes, they have dark brown eyes (where it was white before!) from that on ...
- anyway thanks for posting this nice video!
Today after many years I finally tried and got it right at first try. Highly recommended!
Cool music, fun project, and enjoyable to learn the process! Thanks for Showin us how its done!
he didn't say how to dispose of ferric chloride - please don't put it down the drain!
Andrew Waters how do you dispose responsibly?
Literally put it back in the bottle it came from. Most of the copper will settle as sludge. There's no need to dispose of it for a very long time.
Make sure you neutralize the acid on the circuit board in a bath of Baking Soda and Water BEFORE you rinse the acid soaked board in the sink with cold water, otherwise the etching solution will destroy your house's drain pipes and enter the environment! D:
It's fun watching these pre-JLCPCB at-home-circuit videos.
seen this video years ago an got me into etching found it again an by far the best video out on how to
Ferric chloride is horrible, and 20 minutes wait time is a joke. I prefer a mix of hydrochloric acid and hydrogen peroxide. If it isn't smoking, add more hydrogen peroxide to taste. Etching is done in 2-3 minutes if you stir a bit, and the leftover HCl and cupric chloride in the container can be reused a number of times, by adding some more hydrogen peroxide when it seems to lose its potency.
+John Tsiombikas You're right. I had been etching PCB's for a longtime with sodium persulfate and it took almost 30 mins. That stuff is also pretty expensive, it had been a longtime since I done an electronic project. I will start with this hobby again soon but with better equipment. Better solderstation, using silkscreening to create professional PCB's. I'll also make a DIY etching tank with plexiglass. It's very cheap to make one yourself instead of buying one.
Table salt speeds up the reaction and can pep it up if it starts to slow down.
John Tsiombikas have u lost ur mind ? Ur crazy
Why is a twenty minute wait time a "joke"? I'm just considering that the board(s) could be used for years, so spending twenty to thirty minutes during this step of the manufacturing seems a reasonable investment - especially when compared to the many days or weeks it cane take for a third party manufacturer to produce the board(s) for you.
I also feel that the satisfaction for creating your own circuit board(s) should out-weigh the whole process. If, however, you wish to mass produce your board(s), then certainly try other processes in order to reduce manufacturing times.
I feel the bigger picture here is that anyone can create their own circuit boards, and even their own circuit components, at a low cost. What does it really matter if we need to wait minutes or hours to do so? The process of creating your own components, and thus the feeling of accomplishment, should - in my view - balance the effort required.
Note: Don't put too much hydrogen peroxide in the solution! Using too much hydrogen peroxide can result in the production of chlorine gas, which can be deadly if not well ventilated!
That is just damn cool !!!!
Made my first pcb in the mid 1980's with a radio shack pcb etching kit.
It was a much simpler method, but needless to say, it didn't look nearly as good as yours.
Thumbs up for the purple lab gloves.
Wow thats actually quiet amazing to watch! May the force be with you!
Very cool for a do it yourself construction of a printed circuit board, when you have all the materials need.
Thank God for you. I have been trying to find a simple way of doing PCB's.....all seemed too hard, ...........and you've demonstrated a very easy solution. Thank you.
Excellent work. Really helpful to beginners.
The wall in the background reminds me of my student room at the university of Essex North Towers. Great video, cheers!
Thanks for the tips and procedures to do the etching.
really well put together and narrated, nicely done.
Really want to try this! Great video.
This would be a fun project to do one day. Thank you for making it.
That looks like a good fun project to do.. Thank You for the instructions...
I remember using a permanent marker to draw the circuits when I was in High school to make my own and it sucked!! This is awesome! Thanks man!
I am most impressed, thank you, I just learned so much.
I love this guys videos.
i love your videos Collin! Always great work.
very impressive and looks easy the quality looks just like a one ready made
Making my own PCB's was fun the first couple of times. It was much more fun when that mail arrived with a top notch, superbly manufactured rendition of my design. I still had all the fun of designing the circuit, and laying out the PCB. A factory with the right equipment did a top-notch job realizing it, for a cost that I could never achieve making a lower quality version myself. Many DIY-ers naively calculate cost by assuming their time is worth nothing, and gloss over quality differences.
amazing. great presentation; very clear and concise. thanks for uploading this!
It's a long time aga I made a PCB. You explain it very well. My complimenten for this movie. Greetings, Jan, Netherlands.
You sure know what you are doing! Enjoyed your video!
Nice explanation. Etching seems so simple now .
Thanks for your alternative view which sounds really interesting.
this guy is the real genius in makemag
Thanks for that! I've been doing strip-board forever, but I believe ...it is time.
"wow"I didn't know this was possible at home. Thanks for the nice video.
Damn, every single song you have in this series is really cool.
remarkable tuition in this video, thanks for sharing, cheers
i had no idea this is how they were made. Thanks for the Video! :)
i like it when he shows us how to make electronic parts
Great video! I watched this video with my 12 year old son. It was very simple to understand. Thanks!
I remember in my first year of an electronics class we used nail polish as resist. We literally had to paint the pattern using the nail polish brush. Imprecise but did work fine for simple circuits and it was cheaper. When we moved to more advanced circuits we used toner transfer.
Why is some people dislikes this video? This video is very helpful.
Outstanding! Greetings from Brazil, friend.
This earned you another channel subscriber.
You Know it man!...Its all about the HEART and FEEL of the Board!!!..I Draw my Simple circuits out by Hand with Sharpie...This makes the CIrcuit 100% Hand Built!...
No BSing around! Great vid!
This is a really excellent vid! It is so well photographed and narrated that it is hard to believe it is not the work of a professional crew - ah - 'makemagazine'? Don't know who they are but they do a first class job. Am definitely gonna have a go at this even though I have zero background in science.
Awesome! Thx for the info. I will be using your method soon.
Excellent video. Thank you!
I made my first one this weekend! MUST. ETCH. MOAR.
Wow, I am really impressed at how you can use pre-sensitized board and a normal lamp. I have always used a UV box at school. I have looked at getting my own but it is so expensive!
YESTERDAY i watched a video with collin and i thought "man, this guy is awesome, post more videos with him"
...so, thanks a lot ^^
Great info, great sound, great video!
very handy tricks. printing two and using a sharpie to correct the smaller empties. good vid.
Would love to try.
wow man, thanks for the bravery, i think i might just try this!!
the photo frame part is really a good idea!
THIS IS QUALITY CONTENT I SUBBED AFTER WATCHING 5 SEC
Appreciated that you posed the part names at the end.
Having worked as an electronics engineer where our PCBs were made on a production line, I'm keen to try this home method. Having watched many videos with people using laminators, I'm fairly sure this is going be a more sensible method.
This was so fun to learn about thanks for sharing :)
I made plenty of etched circuit boards.. all of them were made in a brightly lit room, and all of them work perfectly fine.
What a great video! Good job!
Awesome video. Awesome explanation. Awesome How-To.
Thanks!
Thanks for the kind words. I have finally perfected the process all the way to solder mask. It comes form a conglomerate of others work and tweaking it. In a nutshell, there are papers out there saturated with silicone oil that toner prints to with no problem (assuming the write paper) and little pressure initially with the board hot and flat and clean. It transfers perfectly then once stuck in the right place, in my heat laminator2X. Cooled and done right it peals right off and reuse the sheet.
