Please make constant current led driver ( PT4115 )

[@marcinwitkowski2981]

This is SLA type 3D printer not Laser Projected ones... Great project !!!!!!!!!!!!!!!! I keep my finger cross. For png you need to see work of person "that project" on You tube. I hope i help U ♥

[@notyourbusiness3026]

You can use IrfanWiev to do a Batch format change.

[@claws61821]

As mentioned by Marcin Witkowski above, this is an SLA printer, not a DLP printer. DLP uses a micro mirror array to focus and refract the light source, much like in video projection. Aside from that, thank you very much for providing a detailed tutorial for this build! And please include an air filter for VOCs in your build chassis for your health and ours - don't buy into the hype of some of the resins that refuse or redact their SDS!

[@rbmwiv]

I like the fact you are building your own tools. I have mechanic for 30 years and most of the specialty tools that are necessary for certain jobs and the tool is $500-2500 that you won’t use that much. After seeing a picture of the tool and the knowledge of what it exactly does. I will use welder and other stuff to create my tools. My favorite was a top dead center holder and it was just a metal cylinder of a specific diameter. Was $199 made it in under 10 minutes out of scrap metal.

[@adriaanstruwig7921]

Can't wait for part 2, seriously considering building one. Thanks for all the inspiration!!

[@techdiyer5290]

Monochrome light filter: Ive heard that it has a longer life span than the rgb version

[@gabriel79049]

perfect, would there be a part two? assembling the mechanism

[@wedkarzkosma]

Versatile, cheap, open source machine. Cant wait for part two

[@sajalacharjee7008]

That's super cool idea. Can't wait for next part.

[@celsoffraga]

You might want to keep the backlight layer that is closest to the screen, it is a fresnel lens (they "align" light), wich will probably lead to reducing needed UV exposure time.

[@ELECTRONOOBS]

Yes for sure I'm considering some sort of focus lens or something. Thank you!

[@JohnJones-oy3md]

BRB, need to disassemble my 27" monitor. ;)

[@stephensu4371]

i cant wait to see next part

[@vizionthing]

excellent project, cant wait for part two, three and four :)

[@robb233]

Amazingly informative ! Breaks it down so nicely.

[@retailhideout6797]

I’m ready for project to continue !!! Awesome work I plan on building

[@jana171]

Wickedly interesting, even though I dont really like the resin printer type, this video has definitely caught my attention🤔 Awesome !!

[@Isaac_Diggs]

Awesome , can't wait for the next part

[@SeanHodgins]

I've left my project for too long... 🤣 Can't wait to see how yours turns out!

[@mehmetckcan9239]

You both are great geniuses. I like your content very much.

[@ELECTRONOOBS]

Are you working on something similar?

[@SeanHodgins]

@@ELECTRONOOBS I made the Christmas ornament 3D printer a couple years ago, but I wanted to update it and make it into a more generic tiny printer.

[@ELECTRONOOBS]

@@SeanHodgins just watched the video and is basically the same concept, si awesome. Maybe you will make a second version with a better stepper motor :) I've seen a project called lite3D that is also based on Arduino. Now that I've started I don't see this project that difficult anymore and I think I can get decent results and even pass to a bigger screen. I would like to have some monochromatic LCDs compatible with Arduino but I couldn't find one...Keep up your good work and thanks for your comments :)

[@mdev3987]

Story of my life 😂

[@andycrask3531]

Awesome im so excited to see how this turns out

[@antonio.stefanelli]

Simply Crazy 🤪 I've subscribed to see the next episode , thank you guys

[@harikamalakarreddydarapu7410]

Awesome project. Waiting for part 2

[@Hasitier]

Try IrfanView. It has a batch converter function. You should be able to batch convert your png files into bmp with it.

[@YoutubeBorkedMyOldHandle_why]

It has long since been a pet peeve of mine ... when people recommend IrfanView. I have nothing against IrfanView, but I prefer XnView, yet nobody ever seems to mention it. XnView has a great 'batch processing' feature built in. (The same guy also offers his dedicated 'XnConvert' program.) However, if you want to include 'image conversion' functionality in your applications (what Electronoobs wants to do) ... ImageMagick might be the more professional approach. It is basically a library with a ton of language interfaces. (A bit of a learning curve though.) All of these are free and 'cross platform' solutions.

[@Mr.Leeroy]

yeah, or FastStone Image Viewer, which is a better viewer overall and also has convenient editing/conversion tools built-in.

[@andsto]

FastStone and XnView came to mind for me.

[@parthsinghrajput1062]

Bărbați-vă videoclipurile Inspirați-mă foarte mult !!! Continuați și inspirați-ne.

[@gilbertogavinelli8313]

Great idea i'm excited to see your success. By the way, I'm setting up the XY control for my column drill table. Thank you very much for your ideas.

[@neofuturist]

Amazing work!! I can see people making armies of these to prints small parts

[@Kalvinjj]

I've seen that quite a few people have suggested image converters, but let's throw another one in the suggestions: FastStone Photo Resizer. Does batch convert easily, and you don't need to resize the pictures anyway, it does conversions between formats only if you want.

[@razinmuntasir1323]

Although I'll never make it but it should fun to see if it works..... can't wait to see the next part.

[@Tapac2112]

Use ImageJ. You can write simple macro to convert folders of images to another format. Just google "imagej png to bmp".

[@kieranshanley7365]

This is a brilliant video. I want to follow along and build my own printer

[@rinokentie8653]

Very interesting again! Thanks.

[@toolzshed]

Cool project dude!!!!

[@omarcusihuaman4261]

justo te hice la pregunta xD, no vi que ya lo estabas haciendo, genial!

[@chris.morrow]

There are many batch image converters you can use. I use Faststone photo resizer, you can batch import and set the software just to change the image format.

[@kirknelson156]

Paint Shop Pro has a batch convert function, you can probably even find a free copy of the old share ware version. I'm still running version 6 from 1999, and I was first using it on windows 3.1, got it from a CD that came with a computer mag and have been using it every since. anyways withit you can select a source folder and destination or set to same as source and select the output format. I used to use it to convert BMP files from CDs to JPG.

[@ScienceLab760]

Nice project, i will waiting for the progress, thanks for share

[@EdwardDuckitt]

Very cool project! Have you considered using an ESP32 to drive the LCD instead? The time to a full screen BMP is much faster than a Uno. And you can also display JPG using the TFT_eSPI library. The ESP32 dev boards should have sufficient GPIOs to drive all the accessories.

[@pj8979]

This is a great idea

[@D-One]

awesome project!

[@aebramular9415]

So helpful to me, thanks a lot !

[@sushillad1051]

Bro ,i am waiting next project ,this prroject full fadu ( full awesome) take care , you are every project awesome, you

[@tromtacular]

To convert all your png images to bmp, just use the batch conversion built in to irfanview (from the thumbnails of your image files, it appears you already have it installed).

[@backdemoletor4654]

a great project made by a great youtuber... by the way when are we gonna get updated about your arduino smartwatch?

[@BrainSlugs83]

1. For mass image conversion, use IrfanView, it has the best batch image converter, and I've been using it for over a decade. (I'm a software developer, but why waste time re-coding the wheel.) 2. I'm usually the person yelling at the screen saying, "you don't need an RPi for this, use an Arduino", but I think in this case, the project could be greatly simplified with an RPi ZeroW; you can get one of the off the shelves mini HDMI displays (like all the hand held emulators are using), it has plenty of storage space, and you can ssh your files to the device via Wi-Fi (potentially slicing on the device). My $0.02.

[@SianaGearz]

Pi can drive a lot of different kinds of displays. If you don't mind sacrificing most GPIO, it will drive a 565 RGB screen as well, see DPI display interface. You can get a 3.5" 640x480 screen with 0.1mm pixel size, as opposed to 0.22mm pixel size of the 1.8" LCD in this project, or the 0.15mm size of the 2.2" 320x240 LCD that also works with Arduino. Unfortunately they're not quite as cheap. There's a non open source project NanoDLP for the purpose. I might try to code up something else, it seems the GPU is useful for the slicing, if using the Pi! You can use the stencil buffer to find the intersection between a slicing plane and a model. There's no reason to preslice on the device at all, you might as well just render the layers as-needed during printing.

[@vitorpaixaofernandes1328]

Nice project!

[@jozefnovak7750]

Super! Thank you very much!

[@draftpara2882]

Great work.

[@yogaratchaganb757]

super bro, it is a cool project

[@eemhisolutions9287]

You are very Hardworking

[@leehewitt9559]

Fantastic!

[@ssapp72]

Excellent video! I'd like to build a very small, compact resin printer since I travel every week for work. Something small enough to keep in my luggage comfortably.... but able to print a volume of perhaps 2" x 2" x 2" (50mm x 50mm x 50mm for you metric ppl, roughly). Being able to burn time in hotel rooms printing minis would be a joy.

[@abhishekghosh2057]

Waiting fot next part🤩🤩

[@arieltulian4782]

Te felicito, excelente proyecto y gracias por el aporte. Estoy por realizar una de hobby. Saludos.

[@eemhisolutions9287]

Amazing

[@freehaven-junprince2376]

This is pretty awesome stuff. I know that DLP is best for printing BIG items. How big can you print with this setup assuming you could get a big enough resin bath? Theoretically could you repurpose a screen from an LCD tv, laptop or desktop monitor for a super big screen? Would there be issues with drivers?

[@MCgranat999]

Wow, looks promising

[@tvwrectoss7724]

Hey, where are the other parts? Still making those? Or~ I was planning on building my own and was looking for a good tutorial to follow :) You have a really good idea!

[@ork497]

Hi 👋 Can you post the continued videos about this? This is really cool and i want to build one for myself

[@killenmichel6087]

Thank you for this Video, I want to ask you a question what if I want to make a larger 3d printer with LCD (5.5 in) can this schematic work with this LCD or there will be differences? if there are differences can you tell me what are they? Thanks.

[@atom2319]

You are awesome bro..

[@garthmccarthy4911]

okay love the project however. This is and LCD printer, unless you plane on using a projector. digital light processing (DLP) uses a digital light projector to cure the resin. It flashes images of whole layers onto the bottom of the vat. Light is selectively directed using a digital micromirror device (DMD), which is a component consisting of hundreds of thousands of tiny mirrors.

[@faustodeleon2937]

Wow de verdad te luciste con este proyecto, no puedo esperar a la siguiente parte! y no crees que se pueda usar una raspberry o cualquier pc para la parte de la pantalla y la tarjeta sd,? creo que con eso podriamos tener mas resolucion, tamaño de pantalla y hacerlo mas barato si se usaran pantallas recicladas.

[@femmyvr3290]

Accouple of things i would change, 1: I would make it easier to drive the displays by using AV Screens (yes there lower resolution but there also alot cheaper) 2: i would stack 2 of the transparent LCDs on top of each other for better UV blockage (Especially for tiny display like that one there is some noticeable light leakage) 3: arduino is good but i feel like it could benefit from the more accurate timers on a RPI Pico Instead plus there more in stock 4:S and finally id add a slight diffuser on the UV LEDs as ehile it would work some areas would cure faster than others leaving some oddly placed layers

[@hardnachopuppy]

Finally a 3d printer i can afford to build

[@andreiciora2765]

Foarte tare idee

[@mahdishakiba2978]

Soooo good, tanx a lot

[@user-vz6is6te4j]

great work

[@canofpulp]

Ubuntu has a bunch of really good command line converters. You could use an esp32 with TJpg_Decoder, with TFT_eSPI to do this.

[@vizionthing]

maybe retain the diffusion layer of the screen, if it lets the UV through you will get a more even exposure.

[@Drxxx]

Cool video

[@choolanuwan6396]

This is cool 😍

[@hobbytronix]

Ok bro. Good luck...

[@AleksandrIvin]

Hi. Amazing project! I can’t find the next part of video. Did you share it?

[@jeromebotha8611]

Hi Electronoob, any chance you could make a pcb machine to do presensitised pcb without a mask? I am certain it will allow you too add paste mask and silk Mask provided its uv sensitive

[@freehaven-junprince2376]

Re: BMP conversion - there are many programs that can batch convert files for you. I usually use photoshop. I think ACDSee can do it, but there are many others. It's a pretty common need for people who work with graphics a lot.

[@nivzarfati8318]

Amazing! Are you gonna make a second part?

[@ws302]

Nice!!

[@wadhahzaki]

All respect to you 🌹🌹🌺

[@enricofr7079]

that 4gb card is rare now, waiting for part 2... im curious how do you solder that sdcard module 😳

[@oskarhegner1699]

Love it

[@spedforce9338]

A few questions 1: does any of this require me to use PCB way 2: if so can you link the file or what ever I need to submit to them. 3: what component is for the lights (the orangeish board) 4: when will you release part 2? 5: i will attempt to make it so please link everything i need and need to know thank you

[@ezequieladrianminniti6252]

How do you pour the resin for each layer.. the same thickness each time

[@aaronb8698]

Is it possible to Collage multipal screens together to make one large 3d printer? Would be cool to make super big parts.

[@kevinm3751]

Techsmith Snagit can be used to batch image convert all your images to bmp in one pass. Just select all the images and use the batch image converter, leave them all at 100% scale and at the save step choose bmp and it will do the rest.

[@OrgathmTech]

Maybe you can increase the Resolution by using the rgb subpixels?

[@deveshsingh4214]

You can use java (or any language that works with png and BMP images) to convert to BMP (Load image -> paint to canvas -> save as BMP). {I have a java program, if you want}. Or just create an action of "save as BMP" in Photoshop, then file -> automate -> batch -> select folder and action.

[@yoppindia]

can you suggest an higher resolution lcd which can handle UV light and easy to disassemble and interface.

[@reasonsvoice8554]

From a bit of looking around seems online file converters are most recommended

[@m.luthfi.alhadi]

where is the second part ? btw, cool video mate

[@excitedbox5705]

adobe photoshop has a mass image converter. I am sure many other programs have it as well.

[@markfernandes5674]

Have you tried Imagemagick to do batch conversion of image formats?

[@Kitsu_no_mirai]

Can you make an ESP32 FDM 3d printer for next project?

[@navidulakshan9794]

Good job

[@PhillipHilton]

You can use the command line tool 'image magick' to bulk convert your PNGs to BMPs bro.

[@bogdan546]

Please make a video about external interrupts with set registers and timer interrupts using dedicated pins

[@eraser7345]

wtf That is so creative

[@chayanforyou]

Which software do you use to make schematic? Is it fritzing?

[@Ruminiz]

i have an old 7 inch chinese tablet, do you think its posible to use that screen instead?

[@maunladbalesandusedclothin3227]

i know it's an old topic but can i used an lcd desktop screen as the main mask for the lcd and used 3 watts comb led as uv souce

[@reasonsvoice8554]

Cant you create a folder that will convert all the images you put in there to your specified format? Something tells me ive seen this before Or batch file conversion

[@TheMrmaster0101]

I know that laser printers have the same technology and I always wanted to make a 3d printer out of one. maybe you can replace the laser with UV laser, I think it's hard to convert paper movement under a resin bed but that printer would work with JPEG and have a better resolution

[@vivekchauhan7468]

Nice project. Try to make diy dot metrix printer

[@JohnGin.]

Hi, I noticed you have irfanview installed (by icons). So, the irfanview is the easiest way to batch convert all pictures. In the File menu is "Batch conversion/rename". That's exactly what you're looking for.

[@ELECTRONOOBS]

Oh, thanks. But can I convert all of them at the same time? We are talking about thousands of pictures... One by one would be a lifetime.

[@thestraynetwork]

@electronoobs Yes my friend, that's what "batch" is referring to. When you "batch" convert, you are converting multiple files. I have used Photoshop to batch convert & resize a folder full of images

[@JohnGin.]

@@ELECTRONOOBS Yes, sure. Just select a folder, click "Add all", choose Output format, Output directory and click "Start Batch". In Your case dont use advanced options (checkbox under Output format), this is for resizing, croping, and many other adjustments.

[@zonemyparkour]

I met Irfan, cool Bosnian guy.

[@Ech01378]

Really cool, as always! Just take care, uv light is a powerful and dangerous radiation, even when it comes from small leds..
