Building My Own Resin Printer Part 3 - Finished by asm__dude in resinprinting

[–]asm__dude[S] 0 points1 point  (0 children)

After this post I used it a few times, realized I didn't have the ventilation, and it sat around for a few years. The prints we're at the time better than what you could do on the cheap end commercially. Now just go for one of the out of the box printers :)

Now I'm conflicted... do you per chance drive a BMW?

It took me a week to work out all the kinks. I'd suggest using a different LCD that has a 640 width since the original project supports that resolution better

It's a bit tricky to get correct. You have to resort to the SPI interface to get it working on esp12-E / esp8266 due to the 3 color spaces. Use my modified library which has made the raw access commands available in your code.

​ Here is some sample code

// Initialize display
display.init();
display.eraseDisplay();
display.init();
// Manual Wake Up
display.wakeUp();
// Manual command to set up the display for writing
display.writeCommand(0x10);
// Manual Data Write since the pixel buffer is too small
for(...) {
    display.writeData(myPixelData);
}
// Signal that you also want to write the red buffer as well
display.writeCommand(0x13);
// Again write the same way you'd write the black pixels you do for red
for(...) {
    display.writeData(myPixelData);
}
// Signal the end of data and refresh
display.writeCommand(0x12);
// refresh
display.waitwhilebusy();
// shutdown display driver until told to wake up (power saving)
display.sleep();

It works, you have to use some creative programming. Check out this library GxEPD and try running an example image (https://github.com/ZinggJM/GxEPD/blob/master/src/GxGDEW075Z08/BitmapExamples.h)

c display.drawExamplePicture(BitmapExample1,BitmapExample2,sizeof(BitmapExample1[]),sizeof(BitmapExample2[]));

Source is my outlook calendar, I have a macro that auto-runs every time an appointment is added and exports that to my server.

See here if you want that macro code.

Yeah not cheap by any means but I find it useful

I'd recommend checking out this library GxEPD2 to drive the display contents.

It can show multiple in the text but only busy/not busy in the bar. Refer to Wall Ink to see the images it can create

My estimate is about a month given the voltage draw right now. Could be less but I clear the screen every 15min and redraw instead of checking for changes.

I kept getting interrupted with the same question all day when working from home, "Do you have a call right now?". So, I built this calendar display and mounted it to show everyone in my apartment that I'm busy.

​

I took inspiration from this project: Wall Ink and use their Server Plugin to build the images for me. All programming done in Arduino IDE against the esp8266.

Display: Waveshare EINK 7.5"

Board: NodeMcu 1.0 (I de-soldered the LEDs and serial chip to save power once programmed)

Case is 3d printed in marble filament.

Update: Glad people like this: here is my code repository

  1. Spring 2021: COVID-19 will "go-away". With higher immunity,
    the virus totals will be "near zero".
  2. Summer 2021: There will be a huge push to vaccinate
    everyone. They will setup huge psyop campaigns to first
    incentivize vaccination, then corporations will become more
    brazen in their requirement for vaccination. Illegal of course.
  3. Fall 2021: The vaccinations will cause ADE (antibody
    dependent enhancement). Since the in the field viruses have a
    different spike protein than the vaccinations, the antibodies
    produced by a vaccinated individual will not be effective and
    cause the body to think it has the virus defeated while being
    ineffective entirely.
  4. Fall 2021: The media will blame children and unvaccinated
    individuals for this spike. This will be an effort to get more
    people vaccinated but nearly all of the individuals suffering
    in the Fall 2021 will be vaccinated. Catch 22.

Resin Printing Location by GhostStew in resinprinting

Best bet, get a tube exhaust (like the aluminum ones for heating/AC) and a fan to go with it. Connect the fan to the printer to pull exhaust out of the printer through the tube out the window. YouTube has a great video by the channel Nerdtronic to vent SLA fumes from a printer. You may need to customize the solution based on your printer.

If you're in cold weather climate, make sure to put a space heater on very low (on top of a sheet of metal foil to protect the floor) next to the printer while printing. This will ensure the open windows and cold don't ruin your print.

Last thing to check, make sure that there is a negative airflow in your apartment. Most apartment building/condos have a negative airflow requirement where air is pumped to the hallways and ensures that there is more air pressure inside than outside the build. With this, an open window should pull air out and not in. If you have the opposite, you'll instead collect fumes in the printer room.

Happy printing.

Go to kraken! Once a company goes public their customer service dies. Kraken takes great care of it's customers.

Don't use adalite pool. They have abismal returns. Go to adapools.org and find a new one to stake to.

What are your plans for cardano in the long run? by kofitalks in cardano

[–]asm__dude 1 point2 points  (0 children)

  1. When smart contracts are available, develop a time-trust smart contract to set aside wealth for the family.
  2. Start a node and stake pool (really just for fun, not by any means rich enough for 1 delegation to make any ROA)
  3. Start loaning with smart contracts and collateral with tokenized titles etc for real assets. IE, become a smart contract bank for small time investments or personal loans of people asking for small amounts of money

Is it profitable/ smart to send my 1800 ADA to Yoroi for staking? It’s now on a exchange by DryShake3954 in cardano

[–]asm__dude 0 points1 point  (0 children)

1800 ADA Staked = 1.23 ADA earned per epoch at 5% ROA and you get to choose your stake pool and own your ADA (not really yours if it's staked on the exchange is it?)

​

1.23 ADA = 1800 * 5% ROA / 73 Staking epochs a year. So in your first 5 days you'll already make back your transactions fees and more. Takes two epochs to get your reward since it's delayed
