Arduino GIGA R1 has builtin USB host functionality and two USB ports so you can connect USB directly without additional hardware :)

That is so clever, I clicked on this video wondering what sensor would you use and led + ldr is so brillant!

Any changes to the AR Tool landscape since this video was made? For example, Flutter , ARLoopa, or Flet/ARCore ? I'd like to make an Android application that can find components from a circuit board! Just use your camera and it will overlay a marker on the component... however, not sure if there is a minimum marker size , and if it can be overlayed with such high precision. For example, if you have a sheet of paper with a grid of squares, say 50x50.. if A4 is said/entered, could AR use a fiducial on the paper to calculate how far into the grid it needs to place a marker (scaling it based on the the angle and how close the camera is to the sheet).

I found that existing morse code decoder applications (CW Skimmer, CWGet , morsecode scphillips translator, etc) aren't very accurate.. this approach seems much more reliable!

Hi ! Thank you for this great video Do you think it would be possible to do the same by just adding a mic and a speaker instead of using the ones on the phone ?

Great explanation, thanks. If you use the Arduino power plug, doesn't that provide external power for the USB device as well?

Looking at that large coil I want to make a game where things need to go through that hoop and they will light up when traversing. Haven't figure out what to do with this effect yet

I thought running the Nano on 12v causes issues if you have other devices connected, which use 5v.

As always a great presentation with excellent explanations, im now thinking how to use this in an escape room scenario, the barcode scanner specifically to provide hints or clues. My pc mouse and keyboard are wireless with a bluetooth dongle, could a wireless barcode reader also be used without too much fuss ??

Awesome explanation, and why what library and includes to be used and why. Knowing why can empower us to do the right thing.

i've been doing the opposite recently - creating USB HID devices (specifically joysticks!) using Atmel AVR processors and V-USB :)

A Teensy 4 has USB HID built in for mice, keyboards, joystick, MIDI etc.

I'm currently building a room with some DnD properties, and I think I'm going to 3d print some dice with clear filament, stop mid-print and embed these in the centre of the die. Then they have to throw them through the loop to see which die relates to which colour

Starting now...

When you talk about when the LEDs light up vs when the RFID tag is recognised, what about an arduino or similar that can read the RFID tag and only power up the coil when the correct item is placed on? It wouldn't have the cool proximity-fading-in effect, but it would still work as feedback. Also if you still wanted the fade-in, you could ramp up the power when the RFID is detected.

Sound like this could be used to measure a distance ?

But the 6 analog pins (A0 - A5) on the Arduino can only be used as input pins not output. How are you using the A0 pin to turn the relay on or off?

Great video, Thank You! Please do some tutorials on BOSL2, looks VERY useful!

As a tip for those looking to power these by battery/solar, the built in voltage regulator is terribly inefficient, even when its not being used it draws precious power.

Very nice! It would be extremely interesting if you could do the same project but on a larger scale. Let's say a shelf 1 meter long and 20 cm wide, and each glass that would stand on the shelf being illuminated by a led. What electronic parts would be needed? Thanks for sharing! All the best!

you can install a smartphone vibration motor on the knob and use encoder with allot more step but with no physical detent, so you can do all the haptic feedback in software

Good Idea until you get a Gen Z in the Escape and all that's going through they're minds is "WTF is that?".

How much power does it use?

Wow ~ just found your channel, you are now top of my play list ~ excellent presentation, thank you. AndyT(Somerset)

Seems a bit weak and over complicated :D Lectenna can be cut for specific frequency. Mtech Industries resonator has range of several meters.

fun nice

Atomic14 channel has a great video about how to make those 👍

I don't know how the library code works, but I can imagine that mixing up interrupt priorities can really mess with the accuracy of your measurements (?)

Funnily enough I ordered some of these earlier today and this video just came up on my CZcams suggestions 😂 Hopefully in a few days I'll get to have a play with them!

Cool feedback application! My one idea is to use multiple sizes with a wand / divining rod and you could even use it as a meter that "grows" or "charges up" in strength as you get closer (5mm works further away, then 4mm as you get closer)

Just ordered a huge batch of these from your Patreon Link! Thx

When I first learned that these existed, my first reaction was to run to Amazon and Etsy only to be disappointed that apparently nobody was selling resin-cast dice with them embedded inside. Hide the coil in a dice tray and I think you'd have a pretty neat setup for your tabletop sessions.

How many turns in thr coil?

Would you reveal the name of the driver board ? It is a great idea. I will create a puzzle with that i think 👍 thanks for your great videos

Woww, it's cool! Does anybody know what the name of the driver is? I would like to buy it separately (as cheap as possible :D), and make custom coils so the leds only light up at a small place. Also, turning the coil on and off via a mosfet would be pretty cool, as it could become an even more interactive prop

Disney imagineers had made a 3-coil setup with full bridge rectification so that regardless of the orientation the LED would light up

I had jars of sprinkles that are scattered around the room that you need to collect and place on a shelf. I couldn't figure out a reason why you would need to put them in order. Then I discovered these lights. I superglued a ring of these inside each jar. Unless you look really close, you don't even notice them, but when you put them on the shelf, they "magically" light up a color. It's a really cool effect, especially since this particular room is geared towards families.

First 🔥🔥🔥

Thanks for sharing this video ... could you please share the code with the circuit diagram .

Not sure if you'll see this, but I keep running into an issue where it says I need to select a USB type either 'MTP Disk (Experimental)' or 'Serial + MTP Disk (Experimental)' not sure what I should do about that. Do I have the wrong version of MTP_Teensy or something?

Sir, Can you share your code ?

Thank you for this amazing tutorial! I am observing some issues with the recorded WAV-files. For no reasons sometimes parts of the WAV files seem to speed up to almost double speed. It is for a few seconds (let's say 2-10 sec), then it is working normal again. I can verify that it is no transmission error, the files on the SD card are corrupted in this way. it seems like there is some loss in the speed up parts. Is this likely to be caused by the low memory cache? maybe I have to rise it to double size? 120? I would really appreciate any help and ideas on that.

More BOSL2 tutorials please :)

Outstanding video. Nice to get recommendations from someone who knows what they are doing. Particularly liked the power wiring for the DF. Is the size of the smoothing/filtering cap critical (assuming the voltage can be handled of course)?

Please circuit diagram please

Sir please provide circuit diagram please Please

Hi sir i am from India i want to know . About Wirering of the circuit please tell me

Aggghhhh! Where were you last Halloween? Seriously, had NO idea you could do the touch sensors this way. Thank you so much for the explanation and walkthrough. Haven’t found anything else like this and always learn a ton w. your videos!

I recently got afew of the blue 8 track flash drive boards, came with 8 MP3 files on them however when I add my own MP3 files only 1 will play, and only from the I01/RX tab on the board, I get nothing from the 102, 103, 104 etc tabs. These all work & play the included test MP3's. What am I doing wrong?
