All I can think about when I see people post things like what you just said is how Dr. Dre had a max cost of $14 a head phone yet they where being sold for hundreds. I learned really quick how to make my own head phone out of old ones and heat shrink. Shoot I remember getting some broke high end head phone and replaced one speaker and made and extra 70 dollars because people wanted to pay that much or else they thought it was a rip off not knowing all along it was a rip off from the brand that they needed to worry about and I did test them yes they held up to all outputs before I sold them. even a bread box and making your own circt boards become a big money saver!! you can reuse those tools and save yourself money

[@janmetdepetop6007]

Yes that filter seemed extremely primitive to me. The result is what matters guess. And in the end a lot can be done diferently, better but sometimes would go beyond simple diying. I recall hearing on a forum that I neeed a 10K Ohm logarithmic potentiometer for audio input attenuation rather than a 500ohm linear one for ideal control, to avoid the immediate jump in sound levels as well. They said it had to do with audio levels being logarithmically scaled. So the higher voltage would raise volume too fast compared to a logarithmic one (it uses the bottom part of a logarithmic graph to more slowly raise power levels, of course after that the log pot will raise levels faster than a linear one).

Hi Just wondering what you changed for your screen. I want to do this but I was thinking about using 18650 batteries xx

[@Bryantfstephens]

@@vikkidyer hey it’s been a while since I made it so, it’s hard to remember what I changed without watching the video again. I think it might have been that I used some speakers from a TV and the cavity that I made was shaped differently(and cut one sheet at a time then glued). Your batteries should work as long as to set the voltage for your batteries. I also remember that the way the circuitry worked (according to video) the batteries had to have charge to work even if plugged in to the wall. Basically if you watch it while charging it the batteries drained slower so it was best to charge overnight.

Can you guys please help me the links in the description do not work

[@karthikd490]

Hi DIY Perks - If I may, I'd like to make a video request that can be very helpful for farmers in developing countries like India. The request is to create a centrifugal water pump that runs on the concept of sterling engine, powered by heat from concentrated sunlight using fresnel lens. So to simplify, the fresnel lens concentrates sunlight and generates heat to run the sterling engine, where the wheel of the sterling engine is the wheel inside the water pump itself. This can really help farmers in India who have limited access to power to water their fields. Thank you so much in advance.

[@DIYPerks]

That's a pretty good idea. I will add it to my list!

[@karthikd490]

Thank you :)

[@NERDVilleUK]

DIY Perks check out the tesla valve.

[@SurajGrewal]

Aah! Man,that's gonna be ineffitient.the amount of materials used for focusing such huge amount of light,and size if land covered could have been used for high voltage power line instead. There is gonna be a huge loss of energy ,by reflected radiated heat.

[@karthikd490]

Hey Suraj, I don't think the system would be inefficient or occupy large space. You can generate as much as 2000 F with a 50 inch single point focus fresnel lens. Combine that with the centrifugal pump, it hardly occupies much space. If you intend to put it in your living room then yes, it does occupy lot of space. But if you install it near the wells in farm lands, which is my motive, then the space wouldn't be a constraint. As long as we get the right amount of energy to run the sterling engine, I don't think we need to worry about the rest of energy. In fact, some loss of energy or dissipation into surroundings is good as it prevents overheat and damage of materials.

Any reason why you went for a load of AA over a few 18650s ?

[@CSO3DOnline]

cheap and safer to work with

[@vgamesx1]

+山寨卡屁 Lithium cells are nearly as safe as long as you keep them above 3v, keep them under 4.2v and don't short them out and although it costs more there are also LiFePO4 cells which are even safer. As for the cost, AAs are certainly cheaper but not by very much, especially when 18650s last longer (roughly 400 cycles vs about 1000 cycles) and have way more capacity so I'd say that easily more than makes up for the price difference, but if you go on ebay and buy cheap laptop packs you can get good deals on 18650s at around $1 per cell and are usually decent cells, last couple packs I bought, I received cells that were roughly 2000mah and 2400mah. (9 cells and 12 cells) for me the cost was closer to $1.25 per cell so let's calculate the cost difference using that. $11 and $15 for both packs, now rechargeable AA tend to go for about $20 on an 8 pack at local stores and $35 for 12 pack of quality pack of eneloops makes them $2.5 and $2.9 per battery, now that's an unfair comparison since the 18650s are used but new cells only cost $3-$5 and offer over double the capacity and at least double the lifespan, without counting the added charging and discharging circuitry they are an insanely good value compared to AAs. I'm guessing he went with AA because people are more likely to have them lying around their house and/or merely prefers them for some reason.

[@theLuigiFan0007Productions]

One thing you're wrong about, Eneloop Ni-MH AA cells are rated for 2100 charge cycles, which is much better then cheap 18650 Lithium cells. They hold up to 60-80% their charge for well over a couple years and have a VERY low internal resistance. a.co/cfeNtl3 Price per unit is about $2.65. The new line of Eneloop cells are very impressive in terms of specs. I think they're working on a 2500/3000 cycles 3AH version to be released 2018.

[@vgamesx1]

theLuigiFan0007 Well I meant more so in general terms, obviously if you get some quality 18650 cells and limit their charge to only 4.1v or there about you can get 2000-3000 cycles on those too, but yeah those eneloops are pretty great aren't they? Plus they don't even cost much more than some of the poor quality batteries sold in local stores.

[@theLuigiFan0007Productions]

vgamesx1 Rayovac used to have Ni-MH 48 packs for $70 and 24 packs for $40 on their site. They were 2400mAH and rated for 500 cycles or 1350mAH and rated for 1000 cycles. That's not too either for the price, but I can't find packs those size anymore. I bought a 16 pack of Rayovac Ni-MH batteries a couple years ago (1350mAH version), and last year got a 16 pack of Eneloop cells. Still use the Rayovac batteries quite often, but more for things like flashlights and game controllers.

Another great build Matt! DIY idea: robotic and programmable pourover (like the Hario v60). You'd need a precise heater to heat/keep water at the right temp, a motorized arm to move in a spiral motion over the V60 (so 2 small motors, one for the circular motion, and one to move the valve/water hose along the arm), a pump/valve or just a valve (with the heater above) to let water out at the right flow, and a raspberry pi to control it all. Additional options: automatic grinder that dumps into the V60 so all you have to prep the night before is the filter and putting beans in the grinder. Goal is to have a delicious cup of high end coffeeshop coffee made for you to save time before heading to work/class.

Nice! Great! Why buy a smart tv when you can personalise one. You are a genius!

[@Assitier69]

Really cool stuff. ;) (But i would use 18650 li-ion battery's instead.)

[@surfer2011]

How would you do that? How many cells? in series/parallel? and how about the charging? TP4056 can only charge 1 at a time?! Thanks for your help

[@vikkidyer]

​@surfer2011 hiya I'm just wondering if you figured it out as that's what I want to use xx

[@KCisScreaming]

i wanna get these skills. this guy probably saves a bunch of money by making things like this

[@avgoustos1]

I feel stupid every time I watch your videos. :(

[@samus8430]

Me to

[@DD-ow4or]

i feel stupid man and shit bcus i finished highschool studing electronics and basically idk shit bcus well i know damn well i skiped classes like an idiot but by seeing this projects i feel like "why i did that why ?? this could be awesome if i took part and learned it fuckkk"

[@IpwnUfirst]

Wow, mindblown. You gave me a lot of inspiration and motivation. I have a broken laptop sitting and waiting for the revive it, but I will evetually turn it into something as epic as possible, thank you!

[@MagicMahn]

TV companies hate him!

[@ChrisBrown-wr5wf]

Interesting build. (You're quite a prolific builder!) I know it would alter the contour of the build, but it might be worth looking into "C"or even "D" cells for a longer amp/hour. I like the idea of the Chromecast. That might be a way to send the signal from camera mounted on a crane to a nearby monitor. Finally, the bendy arm at the end. As a DIY-er, you might look at a photo item called a "Gorilla Pod" by Joby. That would give 4 bendy arms, add a few croc clips on the ends ...

[@jean-danielg4419]

I SUGGEST USING FUSE IN CASE OF OVERVOLTAGE FROM THE STEP DOWN!

[@fraknrak9111]

When using vinyl wrap on a surface with small holes, place the end of a vacuum nozzle behind the hole while heating the vinyl to essentially vacuform it, looks neater than cutting and tucking or using a pen to colour it in

[@vyladence]

Fantastic project, Mr. Perks! The only thing that i would change is putting the battery meter on the front, such as in the sound bar. Still being impressed by your videos! Glad i found you!

[@systemadminn]

"Next week I show you how to add a foldable keyboard to our home made computer" I expect we will go full circle any day now and we just end up with a laptop. 😂😂

[@Vaisero]

im sorry but that speaker set up is mad amazing.

[@philipwpartain]

Dude, I thoroughly enjoyed the video! I do have a legit question about the bass speaker/chamber/port. I realize we're not designing/building for the New York Philharmonic, but does it change the characteristics of the sound when the port length is determined, then you effectively shrink the space by putting the amplifiers in that chamber? This may be an acoustic 'red herring' on my part, but that's why I'm asking. I know just enough to be dangerous. ;-) Thanks mate, and again, great work!!

[@DIYPerks]

Yeah, it will affect things very slightly. Whether you'll notice is a different matter! I did my testing with the amps inside the enclosure just to be sure.

[@7274_]

DIY Perks what is the camera that you use in your video's?

[@ElijahLeung]

DIY Perks I'm surprised you designed the speaker factoring the box in. When designing a sub the box is probably the most important part of it. You should partner up with barevids lol.

[@MultiSamuel95]

I was wondering if you by any means could update the material list as the one you’ve posted has products that are no longer available. I’d like to try building this project

[@illegitimatecrepe1990]

What I've learned: with a soldering iron and glue anything is possible

[@gourabchakraborty9038]

You r really awesome. I didn't know that making an additional screen nd also a tv would b this easy. I will follow this process nd create 4 additional monitors nd add them together to create my own big gaming monitor. Thanks for showing d path of getting a better gaming experience by saving lots of money. Hats off to you...

[@criscolon3612]

I like how the video chosen was animals going insane on each other XD.

[@rsomel6628]

7 years on I came across your video. And subscribed too. 👍

[@xX1KiNg1Xxl]

5:05 "Free svg files for this are in the description" ommm nop?

[@pedroclaro7822]

Could have used the laptop's case as a shell and battery for the monitor - try to fit everything in there and make it look sort of snug, and you've got yourself a worthy project

[@AjithNarayananH]

Loved watching this. but I can't make this stuff myself 🙄

[@TechKidShazil]

Why?

[@estefersonps3]

yes, you are capable, we can all do it, just have willpower and love for wanting to learn, force my friend ...

[@ccvelcro4514]

I have seen alto from you but this this is what I call legendary

[@DanVR001]

[@etro8564]

why does your comment has 33 likes for no reason , or are you just testing some like hacks here

[@Tyrusoconnor]

lol

[@PistolShrimpPimp]

A few things I'd like differently: I can't tell if the 3.5 is accessible but being able to do a quick switch to headphones would be nice for a wireless display especially. Having maybe a second bank and a Raspberry PI or a low powered computer with flash storage would be nice to have movies as well, maybe again switchable from the Chromecast easily. I would have another option for the battery indicator, maybe something that let's me press a button because LEDs like that which are constantly on can easily add drain to the battery. A lot of wireless mice actually drain significantly faster with an LED on them and even if it's not as much here, maximizing battery life is a huge priority. Also, not sure if it's possible but a direct outlet passthrough option would be fantastic. Overall, awesome project and most the stuff I bring up is not realy necessary but would be amazing as a v2.0

[@alexandracrawford800]

Many of the controllers do in fact come with 3.5mm headphone out I believe. Using the Raspberry Pi in place of the Chromecast is I think a good idea, but prices will quickly escalate with a Pi-Juice UPS to avoid sudden losses of power. Then a common power storage bank is all the more of an advantage with something significant like 18650's, a suitable controller but use instead LiFe-ion type of 18650 to remove any possible thermal runaway problems as seen on the Boeing Dreamliners (e.g. at Tokyo airport shortly after its launch). Step by step following all the well worked solutions will bring this well designed DIY Perk up to any desired standard. But this clearly talented channel author did it all first in a way that anybody can follow and be happy with the result, do you not agree?

[@walterbartek6830]

Why not use li-ion?

[@markobalatinac7237]

you can

[@walterbartek6830]

I understand that you can. I was asking why not use them. Is there are reason that he went with AA rechargeable instead of using li-ion?

[@HecFCovPe]

Maybe because you can replace them easily

[@floridjohngonzales7485]

I dont know anything about electronics but i like this, so 1 subscriber added to you sir.

[@El_Bartto]

dude, I got a headache watching this

[@cmacks95]

As a Mechatronics teacher this has easily become one of my favorite channels! Cant wait to have my students do a bunch of these projects next year!

[@gabrysur]

I bet you a Sony portable smart TV, that after this video, portable smart TVs ar going to be a thing.

[@QTProductionsofUtah]

They kind of ready are, they're known as tablets.

[@latzobear]

not really. since tablets have functionalities other than just displaying

[@QTProductionsofUtah]

map of Mexico that's exactly my point. tablets can do everything this thing van do, and better too. on top of that tablets can also do plenty of other things that this thing can't. my point is that this thing and smart tvs have pretty limited capabilities compared to tablets. the only real pro smart tvs have are their huge screen size. so why make a "portable tv" that can only do so much and is only slightly bigger and bulkier than a tablet when a tablet can already do everything a smart tv can do and more? the answer is that you wouldn't cuz no one would really buy them because they could do more with a tablet.

[@gabrysur]

Q.T. Productions of Utah you have a really good point, but i still think it's a good idea, the reason I would buy something like this instead of a tablet wold be the price, if it costs 90$ and I need a portable second monitor, this would be better than buying a tablet for that price, a good quality tablet its minimum 175$ I´m talking of the nexus 7, and is only 7 inches, I don't think you can find a good quality big tablet for less than 350$.

[@QTProductionsofUtah]

gabrysur I'm not saying this thing he built isn't a bad idea. I built something a lot like it myself actually, I even made a video about it. I just bought a galaxy tab a for $90 and it outdoes anything this can do. its screen is just not as big. again this thing isn't a bad idea, it's just not practical enough for a company to try to make, distibute and sell. yes some ppl would buy it like yourself but not enough to turn a profit,

[@ThatOneGuySometime]

Just a quick question, and I know it might sound stupid, but why didn't you use lithium ion batteries from a laptop battery instead of Ni-mh AA batteries? Also, why didn't you use two stereo amps instead of four mono amps? I find the PAM8403 or PAM8406 very serviceable for smaller drivers, and they run on anything from 3-6 volts, which means you could have used the same output from the 5v step down converter for the chrome cast.

[@hermantico]

is soldering really pronounced with the L in your area or is it just you? btw I love that accent.

[@DIYPerks]

All Brits pronounce the L I believe. Strange how it's a silent letter over in the US (not sure about Down Under though... any Aussies want to chime in?)

[@chocokuma4327]

yeah mate, we pronounce the L

[@TheBasti05]

In Germany, we say "löten" ! Sounds way better. *rofl*

[@brit1066]

Schroggel Paul YES, the American pronunciation of "SODDERING" is sexual function that can get you arrested in some Southern US states

[@nextgencrysis875]

we pronounce the L in the US as well lol. Unless there's something I'm missing

[@dloc116]

I would love to see more about the charging of the batteries

[@davisa0132]

I got the tenergy charger, i cut off one of the ends to fit the charger port. plug it in then that's it.

[@samzzwaldo]

can you in any chance provide us with a circuit map.. because you skipped some of the wiring process, please if you can that will help me a lot. thank you this project was awesome.

[@dawnabbott1805]

Great video! I took my old laptop monitor and turned it into a smart tv using a Raspberry Pi. I control the Raspberry Pi with wireless using my laptop. For my speakers, I bought some cheap wireless speakers. Although, mine monitor does not look even close to this nice and I love the speaker set up. Thinking I could combine the wireless speakers with your speaker system to get surround sound. Gonna have to do some sprucing up to do this weekend.

[@davidson2727what]

Ok, nice video. But did anyone see that lion get body checked by that giraffe?

[@KyleHatch21]

I'd be curious to know if voltage regulation could be used in a build I am working on. Its a wireless table lamp. But instead of using a 12v or a 5v lightbulb, as many other DIY channels have used, I'll be powering a smart bulb that has an operation range of 100v to 255v. Its a tricky build and I'm facing a few snags as an AC power bank is quite large and expensive.

[@videolabguy]

My rule is simple. If a video gives me at least ONE NEW good idea, it gets a thumbs up. Damn! I can only click the thumb's up button once! Great video! Great project! Thanks! Exclamation point!

[@Ovan61]

Matt/DIY Perks please explain what is your educational background, or what sort of education would one need to take to gain the expertise you have acquired?Did you study computer/electronic engineering or electrical engineering?If I was to enroll in either a 4 or 2 year institution what would I have to major and minor in or what courses would I have to apply to accumulate the knowledge of technology you have displayed with this channel?And these questions are also open to anyone who knows, please feel free to offer your wisdom as well.

[@bhvm333]

Nice workmanship & nice videography. I would've put a direct voltage display rather than levels.
