Here's What Happens When a Carpenter does Electronics
Вставка

- The outside of the case is made from solid maple and the top panel is 1/8" thick aluminum painted black. I finished the wood with three coats of waterbased polyurethane.
I love the simple, clean lines and the stark contrast between the painted black parts and the warm natural wood and amber glow from the meters.
The project uses an LM4780 dual channel chip amp that can put out around 50 watts rms into 8 ohm speakers. Not super powerful, but the speakers I built this for don't need a lot of power.
I designed and made the PCB for the chip amp, but wound up redoing the design and making a new circuit board when I made too many mistakes on the first one. All part of the fun!
Also inside the amp case is another circuit board that has an active filter that cuts out the bass. The amp is more than capable of full range output, but I don't want any low frequencies going to the small speakers and the active filter does that.
I built this amp for these speakers: • Amazing Sound and Cool...
NOTE: The chip amp I used for this is obsolete now, but I have a few from when I was much deeper into electronics 15 years ago.

John - you a man of many talents. I do not even know what the thing does but it looks very smooth and polished.
Hi found pics of this in some random google search some 4 months back. It became my inspiration and I have made and completed an amp with similar design.
Really stumped seeing that same amp pic in video!!
Thanks!!
Wonderful!
amazing, john, you are a genius
Videos under 10 minutes and straight to the point? What a treat!
I've been designing and building electronics, both personally and professionally, for over 40 years. Never built anything that looked this pretty. That woodcraft really brought it to the next level.
Thank you for jumping right into it John! I find myself skipping the first 1-2 minutes of everyone else's useless introduction and subscription/like begging. If your content is good, one shouldn't need to ask. And by the way, you never cease to amaze me with your design and all-around building skills.
I hate the sales pitch every damn video include, I don't need to hear your motivation or family history for me to watch the video. Just roll 1 minute of end credits and bloopers if you need the add money.
They do it (usually at the end or in the middle) because it does indeed increase the subscription rate.
Simple statistics.
I agree completely with the sentiment, but I think as everything in life balance is key.
Very brief introduction would be best. I came from an automatic playlist and had no context for example.
Agree with jeff
Yeah long intros are only for super fans. And John covers super fans with other channels/means
Looks fantastic! Great work, John. I really like the gap through the center. It adds a lot more than I would have thought.
Thanks Drew :)
I liked it too
Good Lord! This thing is as gorgeous inside as out. Amazing work.
I have no idea what this person's making I'm just happy I didn't have to fast forward 10 minutes to figure that out. I'm going to subscribe.
I don't watch John's videos as often as I used to. But I must mention, everytime I see that table saw it puts a smile on my face. Incredible work you do big man👏🏾
Jesus, what rock have I been hiding under to have missed this beautiful channel!
Thank you John for sharing your incredible work with all of us.
Subscribed 90 seconds in.
Cheers, John
You are taking this to a new level John. I love the details - maple case, the backlit VU meters, the center reveal... Macintosh will be copying your style!
That's an amazing project! You make cool stuff and your voice overs and videography/production is just as amazing! Thank you.
I just gotta say, straight and to the point, love it, no long intro I have to skip thru. This video is also amazing that you just build something and design it and poof it exists. It kind of blows my mind I have to say.
that is absolutely beautiful!
Thanks David :)
Hi John, this is a really slick design I love it. I've stopped etching PCB's a long time ago, it's nice to see that some people still does that. But it's also true that most of the PCB's I design have some surface mount piece on them and it's quite hard to etch surface mount for an hobbyist. But I'm super impressed of your amplifier
Thanks, I used a mix in my newest multi-channel amp where I made the power supply boards, but ordered the ones for the amps and crossover boards.
I really like the professionally made ones, but then you have to wait for them to get here, and they are less forgiving if you've made a mistake that needs to be fixed.
@@JohnHeisz I know I make mistakes and I have to fix them with wire wrap wires. But I always fill the empty spaces with pads so if I forgot a component I can put it there, so most of my PCB's have wire wrap wires😉 But between $1.50 to $6 for 10 PCB's I can wait a couple of weeks, having a silkscreen is heaven. I use a lot of ESP32 but only the modules not the development board so it's easy to solder them in place with silk screen, but I elongate the pads I didn't build my oven yet so I have to use a soldering iron. We're far from what I've learned in college with black sticking strip and UV system.
Beautifully smart John, a really nice design. Recycling old parts is a nice idea too - they have a certain feel that new stuff lacks.
Absolutely beautiful craftsmanship! No fuss straight into it. Love your style
I definitely appreciate you getting right into the content on your videos.
I also appreciate the preview of the finished project.
As always. Great stuff....
I forgot you make videos, what a pleasant surprise
Straight to the point is appreciated. I enjoy your videos, thanks John.
incredible. simply incredible camera work, editing, voice over, and of course the actual woodworking and electronics build! love it!
I accidentally stumbled onto this video and from the first words you spoke to the very last one I was in AWE! Your craftsmanship is outstanding! The entire video was incredible!
Thanks for not adding 10 minutes of fluff. Well done, nice you got right down to it. Best of all, that was some awesome work.
I'm relieved that your soldering looks perfectly acceptable. Seeing inexperienced people soldering kills my soul.
I absolutely appreciate the direct to content style. Awesome video as ever, thanks for continuing to make these videos
THANK YOU for getting straight to the point and just going on with the build.
Love all the electronics stuff you make, incorporating woodworking!
Simplesmente coisa de artista minimalista, visual limpo, retro sem ser velho, juntando vários gostos e estilos num projeto só! Caro Jhon meus parabéns o Sr é um artista minimalista sem ser chato ou abusa nos detalhes, tudo na medida e proporção certa, virei seu seguidor a partir de hoje!
Not only unique, but the level of professionalism in the fit and finish created a working piece of art, well done!
Definitely prefer jumping right in, and this build is really inspiring. I’m at the very beginning of my woodworking life and as a composer I’d love to start incorporating music technology into a builds, so this was really helpful. Thanks so much for sharing.
Love it John! Such a sleek design and it looks beautiful. Well done 😁
Love when you combine audio with woodwork. I like to build portable speakers out of good hardwoods and other materials.
That is a thing of beauty. Lovely work. That upcycled power switch was perfect!
Just amazing! Impressed by the multi-disciplines involved!
Very inspiring. Love how you get straight to it, short, sweet video.
This looks like the sort of amplifier which would cost thousands of dollars at an audiophile catalog. Nice work!
It probably would cost a fair bit. John would probably make you one if you covered the materials and labour. Bet it would be a surprising amount.
Absolutely agree with you
Straight to the point, yes, absolutely. I don't understand why anyone wants to watch the same intro to every program, tv show etc. Thank you john.
Yes, finally, someone who knows how to make informational videos. Well recorded and to the point. Subscribed.
What a wonderful job! Contrats and thanks for sharing!
Wow, you’re a genius. The case is beautiful craftsmanship, and the electronics were so neat and clean looking. Thank you for sharing all your hard work.
I luved watching this process, I also loved that you got straight down to it.
Nicely done. Glad to see you're still into this stuff.
Beautiful, minimalistic.
Great job John. 👍🏻👋🏼
Great work, the genie is in putting it all together, from about everywhere !
Thanx a lot for getting to the point right away! SO many UA-cam videos use 3 min or more (sometimes half their playing time) to talk about what they’re gonna talk about 🙄
Very impressive! Beautiful clean lines... beautiful classic hardwood and black metal. Excellent fit of all the parts. Very nice!
Absolutely Beautiful John!
Made quite a few speakers myself and just finishing my second tube amplifier. Great hobby.
This was a masterpeice , you are the person who connected the gap between Carpentry and the Electronics.
yes sir! i hate all those who talk for five minuts telling what they're gonna do instead of showing it. that's why i like your vids. thank you for your content
Awesome job again John
love it John! Keep up the amazing content!
Now that is a great job John, very well done👍👍👍
Beautiful work, sir.
That is one seriously good looking piece of kit.
What a lovely build
Gorgeous! Amazing project…
i love videos that get to the point! thank you so much :)
Used to do this in my electronics class in High school. Awesome job 👍
Amazing project, John! Just beautiful craftsmanship with so much love to details.
Beautiful work, sir!
Nicely done John!
Wonderfull case, the use of metal and wood is gorgeous !
Love how you use mix any other material with wood. It gives me tons of ideas. (I’m not nearly as much into the reverse - the unexpected stuff made from wood, like the bandsaw - but I think one or two of your viewers are!)
That is a spectacular work of art! That was a pleasure to watch.
no random noise whatsoever is so relaxing... I so wish my audio setup was like that...
Outstanding craftsmanship.
Very gorgeous minimalist amp!
Beautiful work!
Very cool, and the little round meter are a great addition.
Just simply beautiful!
Holy moly dude that looks amazing!!!!!!
Very nice. A beautiful piece actually. And functional. I too have an interest in both woodworking and electronics. Being "between workshops" at the moment, this gave me a much needed fix - thank you.
Beautiful and no doubt highly functional, thank you!
Damn - wood, metal, plastics, electronics, you're even artistic! I have trouble making mitre joints fit in picture frames. I wonder why I bother.
That's a mighty fine looking and functional piece of art you've created there. Well done!
Beautiful work! Nice contemporary design and that in wood.
So many skills coming together in one project.
Hi John I first came across your channel looking for hifi related info but now I realise your originally a carpenter vlogger. I love how the two activities are so satisfyingly complementary. Keep up the good work. Cheers from Australia. Peter. ☮️🇦🇺
probably haven't watched a video from this channel in over 2 years but from what I do remember about loving your channel is how you could feel the passion through every moment that you sit and enjoy. But I understand catering to a larger audience requires changing to the smaller attention span viewers who was fast everything. Anyways love your stuff, miss even more the old stuff.
Beautiful piece!
There is no limit to my enjoyment of watching art and functionality being combined. Wonderful example there of just that 👍
Phantastic Video and great inspiration !
Wow that thing is incredible
Amazing craftsmanship!!
What an absolutely stunning design! Simple yet elegant! :)
Great work. Gave me some ideas for my old Heatkit A-7 amps that I am restoring.😊
Very nicely done John.
Beautiful build and nice edit!
Amazing, beautiful - hope you have lots of enthusiastic customers
The vertical CNC mount is an elegant idea, thank you
You brought our years back genuinely nostalgic.
My absolute favourite type of content!
I can get pretty far with an electronics project, but the enclosure always stumps me. This level of skill is something for me to aspire to.
That looks really nice. That looks like something I would buy! Great Job!
John, you always amaze me. I have many sticks in the fire, I enjoy woodworking, welding, electronics, just to name a few. Your knowledge of electronics is a level or so above mine, and possibly your woodworking skills as well, which is why I appreciate your talents.
All the Best, Chuck
Wow... this looks awesome.... Good work 👍
straight to it. love it. liked and subscribed!
Perhaps the most beautiful combination between carpentry and electonics. Esthetic and simplicity.
Stunning design
Cool, that looks very well made!
Awesome very talented! Really enjoy videos you do about this type off thing!
