The plaster should be heated in a kiln before casting into it

The ashes from the coal will be blown allover including into your material. That's from me to you. (propane)

Thank you Tinker & Build! You inspired me and I have the same setup! #Forge #Backyard 🔥🔥🔥

I made one with just two cinder blocks for cheaper

Thank you....very helpful.

What type of solenoid valve should we use for our Arduino-based system, considering it's connected to a container with no direct water source or pressure?

Is it a vaccum

What a blower

Standard Lamp😂

Your perfect for a titty twister

I just burn my relay and found this video. wkwkwk...

I know this is old but is the plaster/sand mix by volume or by weight?

Hi, as much as this is the coolest thing, and my 11yo son would flip out with this, what do people do with the aluminum?

can this solenoid be energized for a fee hours , in the abnormal config ?

Best example of underlying theory without overengineered solutions I have seen yet.

great vid however at 2:40 how does the voltage loop counterclockwise if the cathode side of the diode is blocking, also from my understanding of inductors the current flow should be clockwise when there is a current drop in this scenerio, since inductors resist change in current so a drop in current would mean it wants to keep the current moving in its original clockwise direction.

Ehh please dont cut and strip wires like this.. looks very unprofessinal. Where are your tool? 😅

Wow, fancy TH-cam leaving a video up like this with such dangerous work, really disgraceful and dangerous workmanship, nobody should follow this video in regards to the AC terminations, clearly no clue or capability to deal with AC voltages.

What size of flyback diode should I use if I have 220Vac solenoid?

bro.... you butchered those wires. do yourself a favour and buy some side cutters and strippers.

Does it melt gold?

Pretty cool♥♥♥

speaking of safety, if ur not an electrician pls don't do it with 230VAC

Can someone help me? I need to control 4 relay with a 4 axys joystick. On position 1 of the joystick, 3 relay need to be on. On position 2, 2 relay need to be on. On position 3, 2 relay beed to be on. On position 4, one relay need to be on. Those relay will control some hydrolic valve...

I'm not sure why we're worried about EMF. There's an optocoupler on the relay board you're using. Technically there isn't a way of damaging the controller. Unless you're worried about the power supply that drives the device.

yes you made a good video and the instructions are on point however please purchase a pair of wire strippers and learn to properly connect an AC circuit insure there are no exposed wires by using the proper size or guage of wire and when connecting a wire open (unscrew) the terminal far enough so the wire is inserted and there is no exposed copper hanging behind the terminal.

how to make valve become partialy open and close.? give some idea

WHICH PINS TO CONNECT WITH ARDUINO

Brilliant !

The cringing begins at 2:34

Years ago I did a project and bought an optically isolated relay to avoid the kickback. I never tried it though. Any ideas if I was on a good path? The project reemerges :)

1) dont use relay to do it.. it's very big and it loses a lot of heat and it also have shorter life span. oww and it costs more. Use 'dual n-mosfet board', wiring will be exactly the same. 2) don't use wire made with small wires with screw connector.. it's fire hazard. Use single core wire or add metal things at the end (sorry i don't how they are called in english)

I gound a noce heavy duty propane burner. I wan to make a smelter with. Is it possible with using a hole in the ground and some fire bricks

Do you think I could just drill a hole in the side of my foundry and stick a weed burning torch in the hole?

Does it work from 4 km distance wirelessly??

A most interesting SBC. 😎 Texas Instruments sure dropped the ball by not suppling several robot, drone, and servo car learning kits. Hey kids here it is go figure. 🥳 Great video, thanks.

Wonderful thank you

Amazing, thank you! I'm making a project with an arduino uno + 12v solenoid valve + 11.4 V lipo 3s2p battery. Do you think I can use the STEMMA Non-Latching Mini Relay for this? Or what specifications does the relay need? Thanks

BBQ coals could get expensive it might be a toss-up in cost if you used propane...

I get import errors when I import the Adafruit_BBIO library

Thank you for posting this. I would love to see a follow up video with the Arduino controlling a relay based on input to the Arduino. In other words if I press one button the relay would be activated for one second. If I press a second button the relay would be activated for 10 seconds and if I press a third button the relay would stay activated unless a separate signal told Relay to shut off. I am trying to control an AC motor that will raise a platform to various heights.

That's all cool and all but why under scorching heat of the sun

Quick question, if I just solder a button to the power signal of the valve and a power supply, and then solder the grounds together, will the solenoid valve open when I press the button or no?

This guy is either going to electrocute him self and/or cut his bloody finger off. Redicously nervous, should absolutly NOT be allowed near any shape objects, live voltages, or power tools any time soon.

Dumb Question but is it safe to use this design and do this on grass?

Can you explain how to connect the high voltage circuit? I want a 12V circuit: for the load, on the output side. + goes to NC, - goes to com, but where to wire up the input + and - wires from the 12V battery?

which diode did you use from the variety pack you listed in the description?

1:48 SSH? Nonsense, you just have a terminal session over a serial connection. SSH is a network protocol over TCP. Putty can do that as well, but that's a different subject.

is the surge protector really necessary?? I tried plugging the power supply into a regular wall port and nothing has happened.
