So cool
Real shape of Universe 😮😮😮
That was brilliant. you've saved my life!
I love this, but what if you press multiple buttons simultaneously ?
This circuit would not work properly when you press more than one button. Detecting simultaneous button press require multiplexing.
This has to be one of the most beautiful and inspiring projects on UA-cam. I want to rush out and buy a 3d printer, laser cutter, and all the materials to make this creation. Thank you so much for sharing this. You have another sub from me.
Where do i put the wordlist code ? I got confused
I was scratching my head just now. took me two days wrestling around this keypad problem until i saw your tutorial.
Do you do commissions?? 😍😍😍
No, I have never done a commissions. If you're interested, please contact me via email at hwiguna@gmail.com and tell me what you have in mind.
Very good presentation
Thank you!
thx
I need about 27 inputs from switches (digital). Would you just add more PCF8574s or could you combine with some other pins on an Arduino? Thanks for a great video!!!
Thank you for the comment! Yes, you could just add more PCF8574s. Alternatively you could use a variation of that chip that offers 16 instead of 8. Use one or two of those, or if you don't mind different code for some buttons, you could use arduino regular digitalRead pins and the IO expander. Kinda messy, but doable.
Awesome....
Beautiful
4:16, more like Gravitar.
Very nice Hari.
Give the code of this project pls
Of course. github.com/hwiguna/HariFun_180_Word_Jumble/tree/master/_07_Word_Jumble_NoDuplicate
Bro how can we add iot in your word jumble
I'm going to assume your phone miscorrected you and typed "iot" instead of "word". To add words, just open wordlist.h and create string_101 etc the same way all the other strings are entered. If you really meant "iot", you're going to have to explain what you meant. github.com/hwiguna/HariFun_180_Word_Jumble/tree/master/_07_Word_Jumble_NoDuplicate
How many sides had mirrors?
All 12 acrylic faces are covered with semi transparent mirror films.
@@HariWiguna oh. I wasn't expecting that answer. 👍
N I C E. But I don't understand how it looks like they are connected in parallel?
Thanks. Yes, they are connected in parallel. Two lines for plus and minus. You are correct, those two are connected in parallel. However the third line is actually in series. On each LED there is small microcontroller that has input and output pins in addition to the power. Output from the Arduino is connected to the input the first led, output of the first led is connected to the input of the second led, output of that is connected to the input of third led, etc. In the Arduino, there is an array representing each of the leds. The code sets the color of each led in that array, then the info is sent in series by the aptly named FastLED library. Somehow first led ingest the info for itself, then pass the remaining info the the second led, which ingest its info and pass the remaining bits to the subsequent leds. Pretty amazing really. More info of the build here: ua-cam.com/video/YRvfHhS31sw/v-deo.html
@@HariWiguna Thanks for the extensive answer! I was aware that the data line could not be in parallel but needed to be in series. I miss where you cut the soldered data lines. Maybe this point could be at the backside of the pcb's so you could cut when the dodecahedron is completely build? Another question: Did you install the LEDs and capacitors yourself to save some money or would you order the strips with them installed the next time? And by the way: I like watching the whole video and seeing how you solved some problems. Making these jigs was also awesome. This was the first time I saw the dodecahedron build with pcb's.
Love it, HariFun. I got your latest version of Morphing Clock in GitHub a few days ago with Tony Fleming Video. He mentioned about you and your awesome works on UA-cam channel. Impressive. I got Morphing Clock code for Adafruit Matrix Portal M4 with 64 x 32 RGB LED - 5 mm Pitch. Tony helped me a bit about how to put my SSID and PASS into MorphingClock.cpp tip. For the first time it verified perfectly then uploaded it perfectly. All I see is ' Connecting to SSID ' with three dots animation ........ ' It kept repeated. The Serial Monitor states connecting to my SSID and PASS, calling begin ... then called begin ............. then goes back to my SSID and PASS starting all over again. Hari, I am really needing your help to resolve its issue. I just can't wait to see the Morphing Clock alive and running especially with seconds nicely. Cheers. I do have Facebook. Merry Christmas. 🙂
You are a Genius ! Can you share a schematic with all resistors on the matrix ? Do you think that this method can work for a 900 switchs ?
I want to control it using my ps4 controller please make a video 🙏🙏🙏🙏
perfect !
how works?
Nice take on the 1970's infinity table's and wall mirror's. They were cool back then and even moved with the beat. I made the table in woodshop back in high school.
Nice work.. I was wondering if I could use this to reverse engineer a keypad from a rack module. Basically my idea is to mimic the key preses in the rack via arduino. So in a first stage I would use the voltage divider to determine the values for each key press as input and then, based on the obtained values, use the analogwrite function to "send" the same key press via arduino. Do you think that is possible? Thanks
Thanks. Unfortunately, the analogwrite function does not actually outputs a variable voltage. Despite having the word "analog" in the command, it actually pulses 5V at varying speed. Also, as far as I know, most commercial keyboards do not use this analog method but instead uses a digital matrix (more pins, but more accurate). www.arduino.cc/reference/en/language/functions/analog-io/analogwrite/
Hey hope you are doing well!
Hi! Yes, I'm doing fine. Thanks for asking. I've been making things, just not cool enough for a video. Have you made another attempt at an infinity dodecahedron?
@@HariWiguna Good to see you're still alive! In these times of covid it can be hard to tell when someone drops off the face of the internet for a year, never know what happened! I started work in printing a frame jig since I decided I wanted it to be bigger with aluminum angle bracket as the frame and then ordered a bulk order of LED strips but a porch pirate got to them before I did so I'm trying to decide if I want to invest more effort and money into the project or just turn it into an LED-less piece of decor and sell it on Marketplace or something to recoup the lost money
Any chance you can make this / code it for a pi controller?
Hi Corey, Sadly, I have no plans on adapting this to a Raspberry Pi or Pi Zero. However, If you could find the library to support the display, porting should be fairly straightforward.

Awesome!
3 tall mirrors on hinges. Let a person close 2 mirrors like doors forming a triangle around them. They get to see infinite duplicates of themselves. We did that as kids I the stores where the clothing is sold.
powerfull brother
brother what did you use to control the spider?
I pre-programmed it to do certain movements in sequence. The original designer had an article where he used bluetooth. www.instructables.com/DIY-Spider-Robot-PART-II-Remote-control/
That's a cool rhombicosidodecahedron
Wow. Beautiful
Stunning! A simple little project that was anything but simple!
That is a really nice presentation. Interesting low-cost project, nice end result, excellent camera work, attribution given to designer, GREAT. I know I am six years too late, but we can put that down to the UA-cam 'algorithm'! 😊
Thats cool. I would love to see you make one. 😊
Thanks. I DID make a video about how I made it 🙂 Enjoy... ua-cam.com/video/YRvfHhS31sw/v-deo.html
Nice. When centering in it would be great to also center the selection rectangle.
Wow that looks amazing!
Whoa cool
Bro I need this
Can you provide me the names of all the materials used in this project?
Part names: Arduino Uno, 10K Ohm Linear Potentiometer, Momentary Push Button, 2 line by 16 character I2C LCD module., Breadboard and jumper wires. Have fun!
@@HariWiguna What bout one dimentional mouse? we will be needing that as well, right?
