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 or yours’s, if you like.

MY YOUTUBE VIDEOS

I purchased the I9 Sound Card from Temu or AliExpress and the Phoinikas T-10 from Amazon. The I9 changes input voice to different person, even a baby or small child, old men with deep voice and or echo chaimber....

The original designer used Raspberry PI, but I don't know much about it, so I used Arduino NANO, servo controller PCA9685, rechargeable batteries and Battery Management Unit to power and charge the project. Original project is here: https://www.instructables.com/Animatronic-Eye-Mechanism/ GitHub files: https://github.com/czecht/Wondering-Eyes-Arduino-NANO.git Both files are there at GitHub and you can modify them, and or the Sketch for Arduino, as much as you all like.

I have not done something like this before, but Saturday and Sunday I devoted some time on my Fusion. And my 3D printer was working overtime, so I could finish this contraption, before Monday's meeting. Here is an a example I use: https://www.amazon.com/Electric-Reducer-Electronic-Devices-1218GEN20/dp/B0BS9K9HZ9/ref=sr_1_4?crid=1WTY2Y82ZJ13K&dib=eyJ2IjoiMSJ9.-H-3iRXP8KcYaOqkM4GoQgTvrfpb_3WXl_Dq77hebpi-iAnsvGgMKJ2eKeOLVUqJDepxJAd2xLSfJ_NA2i2TJCTwwyu_6B3w_kBgoq_NS_Br0H4Iuv3JV8BIPuCwY8-pAO4t3RN46EQLesh9f2oLQQB17WVQM1Y207wCpBwi1f5jXMqL1YYh9TwdpESC5EVVKl0_Ih1kC9pCMZU8HMZJqInNSRSpchonrf1BZTH2r_8.tZ5coitdit-0P-EkTAo-AmlD6T5PQC5ygb-hvlqTgv8&dib_tag=se&keywords=mini%2B3v-6v%2Bdc%2Bmotor%2Bcoreless%2Bplanetary%2Bgear%2Breducer%2Bmicro%2Bmotor&qid=1742228029&sprefix=6v%2Bmini%2Bmotor%2Caps%2C123&sr=8-4&th=1 Here is the Voltage Regulator: https://www.amazon.com/ALLECIN-L7812-Voltage-Regulator-Regulators/dp/B0CBLS4FHX/ref=sr_1_3?crid=2DKOW1GRKWMXO&dib=eyJ2IjoiMSJ9.KHtJ_ND5R9hG4w7Pi96ren8058w7GV8_jyGt3Zab2Gtc0PLHUcK0rnm5SiES4jxYRFPEfCI7ekzaXb8pxBe2bHBmdnakJCZdJB093qSKvJ92BB55hRmylD7eUvqKcx6MTS9o3wHFjWcGHfuNVfqTcyVYelDbbEHGzfKVw6cOJt8V-2ZJjBPA4z96qCADdEX-0QWuUM-MmEaGnoybgJymqirebG5KeYqO-62SgMZrfeY.uoTSuhvnuL3pnY2_e1eKPwt5JkGuQU5RE7zOGHvWzeE&dib_tag=se&keywords=7812&qid=1742228097&sprefix=7812%2Caps%2C114&sr=8-3 And here is the potentiometerI used: https://www.amazon.com/Uxcell-a14052600ux0954-Trimmer-Potentiometer-3296W-103/dp/B00SWJZMM2/ref=sr_1_13?crid=3I43A6HD9RP6G&dib=eyJ2IjoiMSJ9.vh1GYBTUVAun80p86vTSAPEsswx1dgllrdua8tbixh-9RvQriT6PyA4FScz7Jb-D4HhsxkKgkGInEONqWSaeaF3zkvamkm17q3iXkk27YtqdWXFog4DLnKhPd37_SEMPAh-_blBA7eckcypCKM4Wx3to-5mM8zLlbae7fsKEO_QbpvNoaCq26O_oXnLyBfrZaPG_EqIY_I6yyTo-Bphs6UYxY7DbKqDu7fec_SvKW5U.2H30ZhdvDHVCvhbEU4YIqadFS-JxnPzXpxR-Bc1ugn4&dib_tag=se&keywords=10+kilo+ohm+potentiometer+10+turn&qid=1742228252&sprefix=10+kilo+ohm+potentiometer+10+turn%2Caps%2C104&sr=8-13 I hope everyone knows 18650 rechargeable battery that I used and small switch to power ON/OFF.

Unique Turntable with 3 Mini arms for my fiend Brian!
They are not just in small size, but inexpensive and doesn't require any programming! Just get a speaker or speakers like I used in this video and plug them in, plug in power source and put some MP3 music on MICRO-SD Card and off you go. The PCB version is loud and require just one speaker, but if you like stereo, the white has stereo output, but it isn't as loud, without amplifier. They are inexpensive and small enough to use with the boards I've demonstrated. If you would like me to show you some, just ask, I have couple of them on hand.
TWO more MP3 players for your projects that don't require any programming!
I just finished Saturday Brian's newest arm, and he came back for it and worn it that same evening. All of their friends loved it and it also made a splash Monday evening at our MakeShift Club, where we make stuff like this arm, electronics, 3D printed items, puzzles and much more! Have a peek: https://www.facebook.com/makeshiftlincoln/ Our member Hari usually takes pictures and videos during the meeting and publishes them later that day, so you can come back every Monday evening (around 9PM in Nebraska) and see what we shown that day.
Newest Prosthetic Arm for my friend Brian!
Very simple MP3 Player for Arduino and it is easy to use. You don't even need any amplifier for the speaker, as long as you use 8-Ohm speaker. You can download my sample files and Arduino Sketch, just install the required driver in Arduino and you're ready to go. Here are the files: https://github.com/czecht/MP3-for-Arduino.git I also recorded little about the 16 sound board that doesn't need any Arduino. The original video is here: https://www.youtube.com/watch?v=QAuEE5kXqjE&list=PLv52A7rm-UViZEOlzZfZOB9Gl8cjS3ze5&index=1&t=6s&ab_channel=TonyFleming
MP3 SOUND PLAYER for ARDUINO
This kit is simple and most people should be able to assemble it and have fun with the 16 sounds. There is a code to download the "manual", but it isn't much more helpful than the page you receive with the kit. It is a fun little project, so you can amplify the sounds, with a simple amplifier and a speaker.
WHDTS 16-Sound Music Box DIY KIT
I'm using gyroscope model: GY-ICM20948V2 because it is more reliable and faster than PMU6050. Make sure to use 3.3V on this GY because 5V is messing up and I could not use it with higher than 3.3V! The BMU is on Amazon under Dual USB 18650 Battery Charger. Otherwise all is the same as on the previous video about this arm. Here is the original video: https://youtu.be/GnkYn0Ff_OM Please give me thumbs up and have a FANTASTIC DAY!
GYROSCOPE Controlled Fingers on Artificial Arm!
This arm is for my friend Brian again, since he wanted gears and a crank handle. So after couple of days, I finished it and tonight I'll surprise him with it.

ME, IN A NUTSHELL

The History

After escaping communism/socialism from (Czechoslovakia that no longer exist) I landed here in lovely Lincoln, Nebraska, USA!!! That was back in middle of 1981, the rest is the best part of my life!

It is the best place to live and grow a family! I’ve seen many great places, traveling with my family across the USA! One can drive entire day and see the beautiful scenery changing or getting better and better. We have fantastic places to visit or spend a week or two exploring and having a great time!

I love living here in the USA! Dreaming as a boy and young men, I wanted to have my own business and I had 2 business at one point…. I started with nothing, but my skills and other talents were enough to fulfill my dreams.

In the USA anyone can make it with honest and hard work work. I must say that I’m blessed beyond my dreams and enjoying lots of great experiences ! Retirement now provides even more time for my family, friendship, hobbies, and enjoyment of everything around me. I have my wife is the best thing that happen to me and our family. We met in 1982 and now we are together ever sense.

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, laser cutter, lathe, small CNC…  and my passion for photography. Metal working tools and machines, and welding machines, grinders and woodworking equipment…too many to count.

As you can see, I have all the tools I’ll even need, so I also help out friends and family or fix stuff around the house.

The most important is to help others!  Giving is not just lots of fun but it comes back to you as blessing you and everyone around you! I love to see the pleasant smile…. when something didn’t work, but now it’s back to serve your friends. Because of this, I’m surrounded with friends I trust and love! Couple of my friends help me if I call them with a project or just take care of our cats, when we are seeing our grandchildren…. Many people can’t trust others, despite wanting to do so. But when you develop a great relationship with people, help them and encourage them when they needed, soon everything changes in their lives!

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 Czech Republic, 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, Vienna, BudaPest (It is actually 2 cities divided by Danube river. So one side is Buda and the other side is Pest.) and many more cities will keep you entertained including Amsterdam!
