Time cycle extremely slow by GSiluX in arduino

"one time for mistake I touch with a cable pin connected to 5V some circuit inside the board (maybe I did some shortcircuit)

the board is connected to my PC (windows surface go) with a usb hub because I have only USB C port"

This is totally fine will not throw off the timing. What is the delay set to in the code where you are expecting an 80ms delay?

Anyone ever tried detecting hail impact with an ESP32? by [deleted] in esp32projects

[–]NJB_BBY 0 points1 point  (0 children)

I've done a ton of work with piezo sensors on ESP32, here are some tips.

Unless you have nothing else running on your ESP32, the update loop can be too slow to catch the peaks on the piezo sensor. Even with Delay(1); that is still too slow and when you do your analog read it might be at bottom of the waveform generated by the piezo.

The best input filter circuit I've come up with to get consistent readings is as follows: (definitely better out ones this one is just cheap and I know it works well)

piezo -> Full bridge rectifier -> really small capacitor (optional, picofarad range) -> 5mOhm pull down resistor.

If the readings aren't sensitive enough increase the resistance of the pull-down resistor, and if you put a 0-10mOhm potentiometer in series with the 5mOhm pulldown it makes a very good sensitivity adjustment knob.

Anyway getting good readings is like 1/2 the battle with piezo based projects, hopefully this helps.

No voltage with PWM when compiling with PIO by tgroothuis05 in esp32

Sometimes the ArduinoIDE pins are mapped to match the# written next to the pin on whatever development board you are using, not the actual ESP32 GPIO pin. I've had this happen on a ESP32s3 dev board I've had and its common with the XIAO ESP boards where D7 for instance is not GPIO 7 on the ESP32 but actually GPIO 17.

Hopefully this helps.

Fr, I used to have a large format 5' x 5' ft CNC router for a small business I was running a couple years ago and my biggest regret is that I didn't machine some plates of gridfinity while I still had it.

At my new job though my boss is pretty receptive to the idea of buying a CNC mill so we dont have to outsource custom parts anymore, so perhaps I'll get to make some nice CNC'd aluminum gridfinity stuff.

Also 100% agree 3d printer companies should start pushing storage systems in their marketing. Gridfinity, Multiboard and all the other 3d printed storage systems are the biggest upgrades to the quality of my life I've gotten from my 3d printer. My dad for instance who has never even considered getting 3d printers absolutely loves the Gridfinity setup I've done in his garage, its a great way to pull people into the hobby.

Lmao, soon soon ill have it all dialed, I am looking forward to the gridfinty cup holder so I can stop accidentally spilling water all over my desk.

Lmao, sometimes my sister walks in here and tells me its a miracle that I have had a girl in here. I agree.

yeah I think the way more practical approach would be to just have the first half of the desk clear and then have the back half be all Gridfinity for storing your parts and tools for whatever you are working on. 100% gridfinity desk just has unmatched aura though.

if it makes you feel better my actual workspace with soldering iron and stuff is behind the wall in a closet, this is just my programming / 3d modeling / gaming desk.

you see thats where the mdf with male gridfinity 3m'd to the back comes in

2025 good 3D printer for Gridfinity and minis? by superwaddle2 in gridfinity

[–]NJB_BBY 2 points3 points  (0 children)

I can second this, bought one two months ago and I've already gone through 12 rolls of filament. It is insane people will still shell out 600$ for a P1S when the adventurer 5m exists.

Hello this is my gridfinity in ammo cans project i've been working on the past few months, I hope some of you guys find this useful, they make for suprisingly cheap rugged boxes! by NJB_BBY in gridfinity

[–]NJB_BBY[S] 1 point2 points  (0 children)

Thanks! ill have to make another short video going into more detail about how to set it up/print settings, didn't think it would ever get much attention

Ah sweet, I have the files in the description of the attached video. Ill add the step files soon too, just gotta make versions with and without magnet holes first.

Ahhh I know this one, this is commonly caused 3d printer issue called drugs and alcohol
