- How to make speed checker for micro RC 1/27, 1/28 Mini-Z Scale using Arduino.
The project costs around 9 USD, much cheaper than buying speed checker from Tamiya.

perfect without music
You don't need music, you have very good content.
Great, very interesting.
Looked like you used a 4cm radius but final product is clearly a 4cm diameter. Damn editing tricks :P
Your eyes didn't play trick there and no editing trickery. 4cm shown on circular cutter is the measurement for diameter but actually what I pulled out was 2cm.
Hey thanks for making all the great videos on this little car! I just got one and I'm really enjoying it. I want to get tires with bigger diameter so I can drive better on carpet. Do you have any recommendations?
WLtoys P929 wheels and tyres will give you a lot more ground clearance.
Wheels bit.ly/2VuqDOa , Tyres bit.ly/2Jnn0In
Mini-Q QQ cartoon car's wheels are also big but I don't know if you can buy them separately.
@@BeaversHobby thanks so much!
can this be made portable with a screen and battery?
Yes, of course.
Can i use smaller bread board?
Yes, definitely. As long as you can fit all the equipments on it, it'll work.
Can I use this on my 1/10 scale?
Yes, you can. Just make an appropriate dish size and adjust the wheel size parameter accordingly.
Hello. The wheel for check speed is big, have more diameter than the other wheels. I think the speed read not is real. Do you consider this?
Yes, I have. That's why the encoder is only for counting the revolution while the calculation for speed is from the actual wheel diameter from the wheel I use. That's what I said you have to change the wheel diameter if you use different wheel and tyres.
I probably didn't explain it thoroughly but the "speed measuring sensor" doesn't count the speed of the object it reads. This is the same sensor you see in Arduino Smart Robot and it counts how may times something go pass the sensor. That's why the diameter of the encoder doesn't matter, the diameter parameter in the calculation does.
@@BeaversHobby Oh yes thanks for the explaination. That's good!! Regards friend!
@@weisy87 My pleasure.
Thank you for this video. Your content is very helpful and interesting. I would like to ask you if it's possible to make a speed checker like the Tamiya one, by using a fixed wheel (the wheel that spins on the "dyno") that works with the car wheel, so i can use various diameter of wheels without changing parameters everytime. I don't know if you can understand English is not my native language, sometimes I'm struggling to get understood by people 😆 thank you
Yes, it is possible. You'll need a few more parts to do that like base, rotating wheel, LCD for live monitoring. If you have a 3D printer it'll be easier to make. However by the time you complete it, it might be more expensive than buying the Tamiya one. I got it for around 30 Euros with shipping from Japan.
@@BeaversHobby Thank you very much. I have two 3D printers. You were right, but now the prices of Tamiya speed checker have been raised up a lot, maybe they are out of production. I don't want to spend 90$ for a Tamiya one.
@@fabriziopandolfi1857 In that case printing one yourself is a good option.
your asset is a little overkill, you can simply use a Reflective Object Sensor like the QRD1113/1114
Thank you. I didn't know about that before. I only have this sensor left from other projects so I just use what I have.
@@BeaversHobby those sensors are very cheap and can easily detect dark/light surfaces in a half cm range. you can paint a white spot on the tire side or to apply a white sticker and you are ready to go.
@@mux000 Thank you very much. ❤️
Can i using oled display for indicator speed?
Yes, of course. You just need the library that controls the display and then show the value to it.
@@BeaversHobbywhy to connect pin arduino to oled lcd sir
@@Wedus-Balap Sorry, did you mean how or why?
How: you will have to refer to the manual of the display you have.
Why: because the display itself can't read from the sensor directly so you will need the arduino to process the sensor signal and translate it to send to the display as text.
@@BeaversHobby How code displays value to oled display
@@Wedus-Balap You will need to look at the tutorial for that specific display. Usually it takes serial out.
👏 Please 👏 use 👏 bigger 👏 car 👏
Tho I like these small projects but I have a 1/10 scale 😅😅😅
Change the encoder to suite the car and wheel diameter in the code is enough to use with bigger car. However I'm quite afraid to do it because, well, it's big. 😆
