What are you making ⚒️ / 3D printing 🖨

Ah well that’s a bummer. I hope you can swing it but definitely understand life happens

Wait until you want to get a bigger printer and decide to print one…

This is what happens when an engineer thinks, “What if we just printed the whole thing?”

SONOFF SV, RDM6300 LF RFID reader, some generic 12 volt “cabinet door lock” thing, a 12 volt USB-C trigger module and a DangerousThings mini fridge full of beer. (waiting on 5volt regulator, currently using the F0 as a 5volt source for testing)

FlexEM just has to get close

But xMagic has to touch the side

It’s also tied into my HomeAssistant server.

File under “stuff I’d love to make but don’t have the time or space for”:

Anybody do any lathe stuff?

Been racking my brain trying to come up with some cool stuff to mold scrap plastic into…

Thinking I could just do some round bar stock and maybe have someone turn something cool

Maybe a little horse trading, couple bars of stock if you turn something for me? Idk

Only have 1 light currently setup, so it’s not as impressive… but it still took longer than I’d care to admit to get it working today :rofl:

Making progress. The hardest part is finding materials. Today I needed a 1/4" pipe nipple in steel at least 2" long, a 1/4" elbow (steel), and a brass 1/4" cap. I went to Lowes, Atwoods, Tractor Supply, Sutherlands, O’Reilly’s, and Autozone.

Atwoods had the pipe nipple and elbow. Sutherlands had an empty spot on the rack for the brass cap. Nobody else had anything I could’ve used. I’ll hit the local (way old school) hardware store tomorrow. They have everything, but not open on most of weekends.

Anywho.

Pic3 Internal view. You can see the end of the burner poking in about 1 o’clock.

My attempt to make a circular burner for heating the base hit a bump. I may see if it’ll work with just one (internal) burner. I’m also debating a hinge / swiveling mechanism / or lift hooks for removing the lid to reload mid run.

First glance, I thought you were making a DiY tornado shelter from the other thread :rofl:

I have a manual and a small CNC :+1:

Are you talking about printer scrap?
Pla is a pain to machine, it melt and blob everywhere :unamused:
ABS is pretty decent if you take it slow

Looking good :+1:
What are you melting the aluminum into?

Eventually, lost pla casting. I’m on a learning curve for learning’s sake.

Immediately, gonna let it drip into the barrel of water to make smaller pieces (shot). Whole wheels are a pita to cut/break up enough to fit in a crucible.

Once I’ve got aluminum shot, next step is turning a 100lb propane tank into a crucible furnace.

Then producing a mold, baking it out, and casting. Which will be absolutely flawless the first time, so no need to rinse, lather and repeat till I get it right. :roll_eyes:

Did you see this?

I thought it was pretty interesting.

Saw this the other day… I like it…
Needs more work on the doors, I only see a few with a door mechanism, so your loosing half the advantage to a x1 by not having a hot chamber

So I finally started messing with Home Assistant (thank you @StarGazer1258!) and loving it!
I want to integrate sensors for all my creepy crawlies, but running into an issue with a DHT11 temp/hygrometer. I know it’s not as accurate as the 22 or the SHTC3 which is in my Amazon cart, just trying to work with what I’ve got at the moment.
I have confirmed that the signal output of the DHT11 I have is on the right-most pin (why can’t they all be the same?), ground is center pin, and positive is left-most pin. I have the signal going to digital pin 7 on my Arduino R3, and the positive going to the 5v, with ground to ground.
Here’s my code that I got off a tutorial:

#include <dht.h>

dht DHT;

#define DHT11_PIN 7

void setup() {
  Serial.begin(9600);
}

void loop() {
  int chk = DHT.read11(DHT11_PIN);
  Serial.print("Temperature = ");
  Serial.println(DHT.temperature);
  Serial.print("Humidity = ");
  Serial.println(DHT.humidity);
  delay(5000);
}

For some reason that I haven’t seen in any comments or questions on stack overflow or reddit or elsewhere, I keep getting -999.00 for both temp and humidity. Does anyone know what else could be the problem? I’ve changed the delay time, quadruple checked which pin is signal, and quadruple checked the wiring to the Arduino. Looking at the DHT lib I’m using, -999 marks an invalid value. Should I chalk it up to something on the sensor is buggered?

Is your sensor a breakout board with a built-in pull-up resistor? If not, you’ll probably need to add your own to the circuit.

I do have a 10k pull up resistor. I’ve tried another DHT lib and it’s still not working, just getting back “Failed to read from DHT sensor!”

Welp, no luck. I guess I just have to impatiently look out the window like a dog with it’s nose up to the window waiting for the mailman to come with some esp32s and sensors lol
