i can't get this Stargate Arduino code to work with my D1 mini in c/askelectronics@discuss.tchncs.de
[–] batvin123@reddthat.com 0 points 1 month ago (1 children)

The code looks like it uploads and fails to make noise or light up the led strip. and the serial output is a garbled mess (I tried different baud rates with no success). I have also check my wiring with a multi meter and scoured any wiring schematics.

i can't get this Stargate Arduino code to work with my D1 mini (reddthat.com)
 

i am building a 3d printed Stargate with lights and sounds using a D1 mini and a DFPlayer mini. The code is from this github repo: (https://github.com/spradlinb/Stargate_3D). when i compile the code in the Arduino IDE i get a SPI error as depicted in the image. I've tried remapping the gpio pins with no success. what am i doing wrong? BTW here is a video of what i'm trying to build: https://youtu.be/y01J-hymaDs

How would I make a HVAC simulator to see what a thermostat would do if the indoor temp was 425°F (frozen pizza cooking temps) in c/askelectronics@discuss.tchncs.de

I do want to stimulating the temperature. Also interesting theory, it would be cool to put it to the test. But I need some way to simulate a thermistor. Also, The testing rig I want to build could be a cool demonstration piece for how a thermostat works. I might donate it to some tech school when I'm done with it. Time will tell

Yeah I want to simulate the temperature readings. No blow torches or extreme heat preferred.

I bought a nest gen 2 thermostat to play with a open source project that revives old nest thermostats (https://nolongerevil.com/). Since I don't want to install it into the home, because it will be a toy. I was thinking of building a test rig using a arduino or esp32 to simulate a HVAC and indoor temperature. I'm IT guy, not a HVAC guy, I think this would be a good learning project. Any suggestions?

I've started writing a Compendium/Encyclopedia on "Digitizing Physical Media". (reddthat.com)
 

I am going to compile everything i know into this compendium. It will cover the legality and limitations, How to obtain and digitize physical media, how to setup Jellyfin for viewing the content, and explain why owning a copy of a movie or TV show is better than paying for the privilege to access it. I would like any feedback and recommended resources that will help my research.

I think my 5g/LTE filter for my TV antenna is dead. (reddthat.com)

So i built a outdoor hoop antenna to replace my cheap and crapy walmart antenna. IDK if the pre-amp fried the 5g/LTE filter or it wad my diy antenna. Is it possible for a 5g/LTE filter to stop working and filter out every channel. I orderd a new filter to see if it is the problem. Here is the antenna tutorial I followed: https://youtu.be/Tg0JjeotXq4 And the 5g filter: https://a.co/d/gwpNo2g

ender 3 v2 extruder crushing filament (reddthat.com)
 

My ender 3 v2 extruder is crushing the filament and snaps thus the printer fails to print. I have adjusted the extruder tension, nothing has changed. I also upgraded to a 0.6 hardend steel nozzle and I checked if it was the nozzles temperature, that made no difference.

Looks like my Samsung smart TV is probing my home network (reddthat.com)
 

i was setting up postmaster on Linux Mint, and i saw that a lot of UDP requests were blocked from one local IP address. I found out the IP belonged to my parents Samsung smart TV. i loaded up wireshark and found out it is sending UDP requests with different port numbers per request. any ideas what is going on, and how i can stop it.
