    My current project, which uses an ESP32, is a Domestic Hot Water Controller. It has temperature sensors which monitor the water in a hot water cylinder that has a heat exchange coil, and the temperature of a solar array. It then controls a circulation pump to transfer the heat from the solar array to the hot water cylinder. It also controls an electric immersion heater as a backup when there is insufficient sunshine. I used an ESP32 so that I could send temperature readings to a web page enabling me to monitor the system on my phone. It also has a "holiday mode" which prevents it using the electric heater whenever I'm away on vacation. The ESP23 connects to a time server so that it knows the date/time and switches back to normal mode the day I come back.

    Stupid idea. Retro PC! At 240Mhz. That is Pentium 1 speed. Agon Light uses an ESP32 as a video card. So I wonder if an S3 could run as a 200Mhz Pentium ( window 98? ). Core 2 as the video driver.. Or. Just a second ESP32! Usb 1.1 is plenty fast enough for a USB keyboard and mouse. Large SD card as a hard drive. Just needs a sound card ( another esp32? ) and you have the hardware needed for a retro PC. Anyone fancy coding a Bios and firmware? Lol

    • @OverSoft
      @OverSoft Před 3 dny

      You can't directly compare clock speeds between a x86 and an ARM processor. An x86 processor can do much more in a single clock than the ARM processor can, because it has a much more elaborate instruction set. And if you want to build a PC compatible out of it, it will be even slower, because it has to emulate those instructions. Next to that: the ESP32 has so little memory, I doubt anyone would be able to built a fully compatible x86 emulator out of it.

      If it’s a dev kit then yes. If you’re making your own board you’ll need to step the 5V down to 3.3V with a linear regulator. The 30 amps is the maximum rated current for your supply and not the amount of current that the board will actually receive.

    In order to make the gaps disappear between the tiles: Make the outer grid walls only 45 % of the inner ones (maybe even 40 %) so the edges move closer together. (Maybe you need to sand off a bit of the panels too) Instinctively, you might choose 50 %, but given, than no clipping together will make the effect disappear completely, you might need to experiment a bit with the amount.

    One rule of thumb for video walls: the optimal viewing distance is roughly the millimeter LED spacing switched to meters. A 5mm pixel spacing is best viewed from 5 Meters or more. Super cheap Hub75 panel LED spacing as low as 1.87mm are available (for less than 1 cent an LED)

  • @WindLighter
    @WindLighter Před 16 dny

    I whould like to see your reasons of chosing ESP for this project. Foe rxample, when I started a bit of similar project (unfortunatelly it took no significant traction online), I had ARM, STM and Raspbery as main options and ESP caught my attention later, when main features of the project was mostly designed. But I desided to still use STM32 as it had the most nomber of pins to arrange LEDs in parallel getting faster FPS, and also there was a lot of pins left to add most of extra functionality and expandability

    • @TheTechRandom
      @TheTechRandom Před 13 dny

      I chose the ESP32-S3 specifically because it has dual cores so it can handle the amount of data it will need to process to achieve a decent frame rate but also its programmable through the Arduino IDE making it approachable for most hobbyists who may want to try a project like this on their own!

    • @WindLighter
      @WindLighter Před 13 dny

      @@TheTechRandom first point is valid, as generating frames on the fly is way faster than, for example, reading data from SD card (it can take up to 5 ms for 4k points), but peak framerate is also limited by speed of LED data transfer - I believe that was the reason that some listings or darasheets state that maximum LEDs per line is 2 or 4k (though tere is no actual limit). but the Arduino IDE is still a method to program a controller so you still need to deal with coding at mid and low level and to interface different libraries with each other. It's no big deal if you're an engineer or at least coding hobbyist. But what I can see, a lot of hobbyists who specialise on practical skills like cosplay, crafting, making miniatures and so on are not good enough to be abe to code and prefer using ready-made devices. Does your approach allow a workflow like step 1 - download a program that casts something to your device, step 2 - buy a ESP32, step 3 - download a program that flashes your code to ESP32, step 4 - connect ESP to PC through USB, and flash it, step 5 - done? Or even better - buy online preprogramed device and download a program to cast something there - and start using it?

    • @TheTechRandom
      @TheTechRandom Před 13 dny

      @WindLighter I would love to sell these as a pre-programmed product someday but right now that’s outside of my scope. For now I will be keeping the project open source so someone can simply buy the hardware and install my pre-written code. Anyone attempting this will still need the basic knowledge of soldering and 3D printing as well as setting up the Arduino IDE but all of those things can be learned for free on CZcams already so I don’t go into the details. I am planning smaller projects for the future that will be more practical to sell and ship from my own store but we’ll see how it goes.

    Looks great! The auto vinyl is a great option and for removing the grid lines it should be as simple as making sure to only print 2/4 of the edges (with exceptions for tiles on the edge of the entire wall). I'm a Bottom-Left edge kind of guy. I do think printing the actual tiles in a different color may help as well. Black give a bit of a screen-door effect, and white might be too reflective. Perhaps experiment with some differing colors? A shade of gray might end with the best results. Can't wait to see the results!

    If you increase the brightness just slightly on the pixels on the edges that connect to other tiles it will help camouflage the gaps. That's what video wall displays do. I really like this project and it looks great. It's super weird that we are now to the point where it's hard to justify projects like this when we can buy screens this size that will probably cost less money in the end. Obviously, that isn't the point, but my frugal side keeps screaming at me when I start considering it.
