TONY’S FUN

I think that everyone should call or visit your friends at least once a week!

There is much more return in giving than you can imagine.

Make sure your older friends see you often – they love to share their life with someone.

I was a computer repair man, my customers are more like my friends. I love everyone, but I do have a soft spot for elderly or handicapped people.

I’m looking for someone in Lincoln, Nebraska who would teach me more about electronics – I love to make some electronics parts into a project!

I’d like to create a hobby group that can meet in my house.

This Marble machine comes with 3 different "ramps" and you can print them all or just one. As per video, there are 3 pins to connect the main body with the ramp that is attached on the right side. You can download this Marble Machine here: https://www.thingiverse.com/thing:5026242

I saw this project here: https://www.instructables.com/DIY-Arduino-Ball-Balancing-Game/ But I made it from 3mm plywood (not from cardboard) and 2 parts printed on my 3D printer. You can make your own parts for your laser cutter here: https://www.makercase.com/#/basicbox and or design the parts with Fusion 360 (or any other 3D program). Here are parts you can download that I've created: https://www.thingiverse.com/thing:6514949 I also have the files for the laser cutter, but for some reason Thingiverse don't like them. So download them here: https://media.cuttingpaths.com/wp-content/uploads/2024/03/16120700/topBox-g5ovsm.dxf https://media.cuttingpaths.com/wp-content/uploads/2024/03/16120657/LargerBox-tvydgm.dxf https://media.cuttingpaths.com/wp-content/uploads/2024/03/16120653/box-eklk2v.dxf https://media.cuttingpaths.com/wp-content/uploads/2024/03/16120652/BottomJoystick-hvgbwo.ai https://media.cuttingpaths.com/wp-content/uploads/2024/03/16120651/Bottom-eyw3rp.lbrn2 Or download a zip file here: https://cuttingpaths.com/designs/diy-arduino-ball-balancing-game/ click on DOWNLOAD button.

I downloaded this project from here: https://www.instructables.com/DIY-Arduino-Ball-Balancing-Game/ And I did not like to make this from cardboard, so I designed it from 3mm plywood and couple 3D parts. You can download the 3D parts parts from Thingiverse : https://www.thingiverse.com/thing:6514953 BUT you can make custom parts for your needs here: https://en.makercase.com/#/basicbox I used Crazy Glue everywhere I needed to permanently attach parts. I also used the accelerant to instantly cure the glue.

There are no information how to assemble these Spinners/Iris, but in this video I'll give you information how to do that. You can download these from: https://www.dxfdownloads.com/free-cinematic-mechanical-toy-finger-spinner/ The Iris can be downloaded here: https://makerdesignlab.com/experiments/mechanical-iris-prototype/

I cut 3mm plywood on my laser cutter and assembled the secret compartment. This is the simplest puzzle box you can make. It doesn't take much time and one sheet 12" x 12" x 3mm is enough for entire project. You can download the instructions and the files for your laser cutter here: https://www.instructables.com/Laser-Cut-Wooden-Puzzle-Box/ Have a great day!

You can find this project here: https://www.freepatternsarea.com/designs/plywood-light-shade-idea-for-laser-cutter/ I made the pedestal here: https://en.makercase.com/#/ Click on the Polygon boxes, and chose the size and many other options, so your design fit your power delivery. You can just install a LED lightbulb if you like. Here are Dodecahedron with programmable LED's I made: https://www.youtube.com/watch?v=uYSsyTngvdE&list=PLv52A7rm-UViZEOlzZfZOB9Gl8cjS3ze5&index=33&ab_channel=TonyFleming A much bigger Dodecahedron: https://www.youtube.com/watch?v=Dw-81TkrbNk&list=PLv52A7rm-UViZEOlzZfZOB9Gl8cjS3ze5&index=28&ab_channel=TonyFleming I salvaged from a broken LED lightbulb the LED's them selves and I used an a LED Tester that tells me how many volts the LED segment need. I'll make a video in few days, so come back and I'll demonstrate the tool it self.

Here is where to download plans and the Arduino Sketch: https://www.instructables.com/Rock-Paper-Scissors-Lizard-Spock-Desk-Toy/ To download Arduino Nano: https://www.google.com/search?q=arduino+nano+pinout&sca_esv=27178ea4ecd47877&rlz=1C1CHBF_enUS1049US1049&sxsrf=ACQVn0-20eCvu4ek_g2BRS582em4jfFxxA%3A1706651788727&ei=jHC5ZcrqK4_W0PEPhq2iiA0&ved=0ahUKEwjK4PysjYaEAxUPKzQIHYaWCNEQ4dUDCBA&uact=5&oq=arduino+nano+pinout&gs_lp=Egxnd3Mtd2l6LXNlcnAiE2FyZHVpbm8gbmFubyBwaW5vdXQyChAjGIAEGIoFGCcyCxAAGIAEGIoFGJECMgsQABiABBiKBRiRAjIGEAAYBxgeMgUQABiABDIGEAAYBxgeMgYQABgHGB4yBhAAGAcYHjIGEAAYBxgeMgYQABgHGB5IuSVQ5AtY_xdwAngBkAEAmAF2oAGYA6oBAzQuMbgBA8gBAPgBAcICChAAGEcY1gQYsAPCAg0QABiABBiKBRhDGLADwgINEAAYgAQYDRixAxiDAcICBxAAGIAEGA3CAgcQIxiwAhgnwgIHECMYsQIYJ-IDBBgAIEGIBgGQBgo&sclient=gws-wiz-serp Here is the 3.7V boost board: https://www.amazon.com/dp/B09YD5C9QC?ref=ppx_yo2ov_dt_b_product_details&th=1 I cut the 3mm plywood using my laser cutter - you can ask someone else to cut it for you, if you don't have one. This sketch you need to run as soon as you make the the 5 pushbutton switches to test them and write down the values copy this and paste it in Arduino IDE: // Button Reader for Rock, Paper, ... #define btn_pin A5 int buttonVal = 0; void setup(){ Serial.begin(9600); } void loop(){ buttonVal = analogRead(btn_pin); Serial.println(buttonVal); delay(500); } When you run this sketch and you upload it to NANO, open the Serial Port and you should see numbers printed every 1/2 second. If you wired it correctly the number should be 0. Push the first button and write down the lowest value and than the highest number. Example: 220-240 Repeat with all 5 buttons. You will have 5 sets of numbers that need to be in the Arduino Sketch you downloaded from the Instructables. Here is where to change the values to your numbers: int buttonVal = 0; int player_choice = 0; int rock_btn_val_low = 1000; int rock_btn_val_high = 1023; int paper_btn_val_low = 500; int paper_btn_val_high = 520; int scis_btn_val_low = 330; int scis_btn_val_high = 360; int liz_btn_val_low = 250; int liz_btn_val_high = 260; int spock_btn_val_low = 200; int spock_btn_val_high = 210; Hope you will have as much fun with this project as I do.

The batteries from AmpTORRENT and Blackube aren't any good! After I purchased several packs, several batteries died without being used in anything!!! After couple weeks more batteries died! Second reason, the batteries fromAmpTORRENT will not work in my Nikon Flash, they overheated and the flash didn't like them at all!
Rechargeable battery brand you should not buy!!!
This video is number 2 about how to control the sound from the ESP32. I couldn't make it in the previous video, since I didn't have the parts, but they arrived today! First test is with the 201 (200 Ohms) adjustable resistor and I've tested 2 speakers using the above settings. Last part I'm using a 3Wx3W amplifier with stereo speakers - ok, the ESP32 doesn't come with stereo, but the amplifier has stereo, so I used both channels from mono input. Old trick everyone knows how to connect both left and right channels to one mono input. Let me know if you like me to test some other combinations.

ME, IN A NUTSHELL

The History

After escaping socialism from (Czechoslovakia that no longer exist) I landed here in lovely Lincoln, Nebraska, USA!!!

It is the best place to live and grow a family.

That was back in middle of 1981, the rest is the best part of my life!

Fun

Few years ago I started to play with an Arduino and electronics again. Now it is one of my hobbies – thank you Hari! But I have many more  hobbies, including 3D printers  and my passion for photography. But that isn’t all, I have tools like a small lathe and CNC (very small), welding and woodworking…too many to count.

The most important is to help others! 

That is what drives me every day.

Favorite Places

I have been fortunate to see and live in other places, like Austria and my birthplace, but my new country USA is by far the best place on the earth. 

Europe and Canada are also very very nice! If you go to Europe make sure to rent a car, or buy a train ticket that lets you visit many great cities! Prague is also fantastic, Nurnberg, Berlin, Viena, BudaPest and many more cities will keep you entertained including Amsterdam!
