DIY Electric Scooter Part 3: Kick Detection & Improvements

Final part of the DIY electric scooter. A micro controller and a gyro are added to detect kicks and let the scooter act like a pedelecs to be somewhat lagal.
A battery compartment is added and a nice 3d printed brake lever is added. The work principle is explained in a basic way and as always you can expect some humor.. enjoy :-)

Guy is a genius and the lil comedy skit of him blowing up is the reason I gave an upvote ..lol made me laugh at 3am waking up the wife and kid 🤣

[@szabonandi]

The animation at 5:05 was brilliant :-)

[@akj7]

szabonandi, it confused me a bit.

[@Nicksperiments]

I’d love to see a tutorial on that animation

[@DAveShillito]

I was just about to post the same thing (that it was brilliant) :)

[@Nicksperiments]

2000jago I wonder if he used Blender for it since that’s what he ushers for 3D modeling

[@bitluni]

it was the simplest effect ever.. as nicksperiments wrote. I took a frame from the video to highlight the path using paint.net and while I was there I simply used the stamp tool to change the original pic. then simply overlayed the original video. used the same section of the picture on the second click just adjusted it for the right placement. many of the effects were done like that. the drill and tap bits was the most difficult since I had to edit 12 frames. blender was only used for the explosions. the main part of the animation was taken from my smoke detector video. I just added the small flying me and scooter to it.

[@jon_raymond]

This is such an amazing and well documented project. It even included some great laughs. Thanks for sharing it!

[@arifindobson]

Best teacher, engineer, humorist, director, inventor. So satisfying watching your videos

[@UnexpectedMaker]

What a FANTASTIC finish to the project... a super funny video, and the assistive acceleration is such a clever idea. I think you should keep it regardless of law changes. It's very very clever!

[@georgecristea9276]

Even if I would not make this project very soon, watching this video was a real joy. Great jobs, both the project and the video!

[@jeremyplatt]

Such a well executed project with fun editing! Have subscribed to your channel.

[@En1Gm4A]

I love these Projects ! Pls more of these :-) Verry well made !

[@sorin.n]

Cool. This Old Tony taught you how to karate-bend metal!? @5:44

[@petrbrazda1064]

I have this same feeling .....

[@bitluni]

you only learn from the masters :-D I actually lost all footage of how I made it so I had to use ToT skills

[@mojo_jojo]

Love it! I'd additionally protect the power cables against wear.

[@azyfloof]

Seen you on Seon's Livestreams so many times, I don't know why I've not subbed before! I love your sense of humour, videography skills and of course the projects :D The ToT references in part 1 were great, too! :D

[@allenleeparsons]

“What’s the worst that could happen?”... I literally laughed out loud and then subscribed

[@annego]

Some really nice editing skills here! Amazing!

[@markusfuller]

superb project and very entertaining video

[@suhasudaykumar3691]

Great video..I am planning to build same kind...is it still legal to build kick assist scooter in Germany?

[@EdwinvandenAkker]

6:21 First rule of video making: A professional video production has always at least one explosion. _I guess you nailed the first rule of video editing!_ *Congrats*

[@ahaveland]

That was fun! Nice touch using the gyro. Opens up other possibilities too such as theft detection if moved while disarmed and use gps + lora ... Probably not worth it for this as you won't be parking it anywhere, but could be worth another project.

[@Rtcmanga_YouTube_Channel]

Awesome project! :) Cool idea to make the drivetrain kick sensitive!

[@Ringer1982]

Your videos are getting better and better!

[@hzlin6655]

maybe there is a hall effect sensor in the motor. you could track the acceleration of the spinning speed . once is founded, then there is a absolute kick

[@adhochero6619]

thats cleaver and the "what could go wrong" part was hilarious

[@MAYERMAKES]

Amazing editing! And of course great project!

[@datahaki]

very funny! nice fire animation on the whiteboard.

[@gr7480]

You are in Holywood, Wilhelm. Yeeeeeees . Great video. Thanks.

[@VENNETRAVELS]

What is the worst that could happen at 6.20 hahaha. Even though I am not that great with electronics myself I love watching your videos. Keep it up Mr bitluni. :) Greetings from Holland

[@johnbeer4963]

nice. i might build one. You might want to put some kind of protection for the battery cable against the metal in that hole in the frame, though. EDIT: Also, with that arduino, how cool would it be to have an accessory display on the handlebars? wouldn't have to display much, battery voltage and speed as a minimum. I went looking on that big china website after my first watch through of your videos and found 8" motors with built in hub brake, could be interesting for scooter 2 :D

[@bardenegri21]

Great video, loved the funny bits too. I'm wondering, could you detect a kick by measuring the current draw on the motor as well, maybe with a non-contact inductive sensor? That's what came to mind first when i saw it.

[@Hihihihi201]

Sir this project looks amazing. Where I can get the code for the Arduino?

[@emmettturner9452]

Can you link to the previous parts in each video? Thanks!

[@tongyuanhe3552]

Great job, first video Ever seen on KZbin converts simple adult scooter to electric. I am currently doing my project similar as yours, I used the same adult scooter but with a hand break, and I am using a 3700w brushless motor with esc at 12s 50.4v. And it used a 25h chain , sprockets to drive the wheel. You should use come up better solutions for battery enclosure, I have my scooter using 12s8p lion batteries that can go about 35 to 40miles per charge. It’s pretty heavy so I mounted on top of the deck, You can consider mount Lipo batteries on the handle bar with quick locks, easily to take off and recharges

[@katchupoy01]

Haha. I really enjoyed this video. Thank you. Brilliant on the kick program. Been wanting to do that but it is really beyond me.

[@madanicherfaoui9548]

Funny and genius, I just subscribed to your channel cause surely I will never get bored with your videos😉

[@DarkFoxDK]

Awesome project. Though, like a few others have mentioned, you should protect the cables a bit better. Especially the point where the battery cable comes through the frame. It looks like that'll slowly wear away the insulation on the cable.

[@Hellsong89]

Link to your site is 404, what kind of battery protection system is in place to prevent them going under voltage? What happens when water gets into micro switch and connects it constantly?.. tough you can just pull the wire.

[@ABID5]

technology + sarcasm

[@KidCe.]

Very well done and funny video as always ^^ When you were talking about the Sensor Values and how to use the integral to distinguish between different types of events that could happen i thought that must be a powerfull tool for my project to ( Motion reactive LEDs ). I dont really know how to find out more about this or any simmilar technices of "signal evaluation", do you have any sources for good information about this? Would help me alot, thanks :)

[@CaseyScheideman]

Thank your for the info on the Arduino throttle control! I wasted a whole day trying to figure this out on my own and I wasn't sure the values to use for the lowpass RC filter :]

[@bitluni]

that values work for 32khz pwm. there is change of the pwm control in the setup() to get the high frequency. you'd need higher values for lower frequencies

[@CaseyScheideman]

Danke! That frequency works perfectly for my speed controller. I am going to make a push button throttle that eases up and down when you press and release the button.

[@electron-1979]

Hero in a half shell, Bitluni power! 200W I Australia. Helmets not required?

[@Arek_R.]

I really hate how governments try to kill small EV, those are literally cheapest and greenest way of transportation. They should support these.

[@Fabrica3D]

You're so cool ... .nice video production ... . cool working in CAD ... nice.... :D... LOVE YOU MAN :D

[@asnandrey]

Ha ha..nice video...love the various graphic effects! 👍 Especially the exploding 🔋!

[@steven-vn9ui]

Genius. Very neat project!

[@DreitTheDarkDragon]

Idea - what if you monitored power consumption with hall effect sensor? Maybe it might be another way to detect kick.

[@difflocktwo]

Or wheel speed.

[@squalazzo]

even if i not always understand or even think to use what you do here, i watch your videos because they're too funny :D

[@stofffpv3128]

came across this video..good content, made well and with wit...subbed

[@CyclingSteve]

I prefer the kick version. Loving the return to home feature at 06:22.

[@CJGanna]

Would it be possible to make a kick assist scooter using a vesc and Arduino? I’m don’t know how to code but I’m currently working on a project that would require this

[@shanehumberstone5262]

Hi I’ve got a 36v 1000w scooter and I need to make it so I can charge the battery pack while it’s no in the scooter,can I just make it as a wire from charger to battery or do I need to have a control box in the circuit,any help will be greatly appreciated

[@nelsonsiliezar3961]

I built one with a similar motor controller. How can I accelerate gradually ?

[@KatteMedZalo]

Best videos ive seen so far this week!

[@alexderpyracc4053]

Thanks for this if a escooter has kick assist it can be used in the Netherlands

[@videos40058]

what kind of 3d printer you got?

[@jpoppinmoneyunit7098]

That video was awesome! Did you code the whole thing in arduino IDE? I want to take a class on coding but no-one thinks I should start with C++ but that’s what arduino uses... any suggestions?

[@bitluni]

in my opinion is JS a good language to start. you have all you need in the browser. It also shares much of the syntax with c++. but you should also be able to start with c++ if you are working with micro controllers. blink program has the same difficulty in any language. and you grow from there by adding stuff. I have used Arduino IDE to keep the requirements simple.

[@grindel80]

The funny switch animation is awsome!! this is the most funny video you ever created! but what happend to you hair?!?!??!?

[@DCGrimm]

The project page is no longer available?

[@CrzyMan_Personal]

I see you are following the footsteps of This Old Tony... Good footsteps to follow

[@maxiheidenreich6976]

nice project! i had a simular idea, but im not that good at coding. would you share your code with me? that would be nice, thank you!

[@re-lax7671]

Great mod and video ! i whas wondering since my e-step has a spedometer inside cant i just let de arduino sense a speed increase by mij stepping and boost that! then pause for a sec til the next kick is sensed ? (kick > boost 1 sec. > pause 0.5-1 sec > re-arm the system again to sense the next kick)

[@bitluni]

In my case it's not clear when the top speed is reached. I am just using a delay. When it's ready for the next kick it will beep. Otherwise the speed up could be detected as a kick

[@JeremyCook]

Neat project, and nicely edited!

[@ofsanjay]

you are the awesome guy really like your videos. Nice animation

[@phizicks]

hahah laughed my ass off on this video. love the funny parts including the battery exploding and rewind on errors.

[@SianaGearz]

Look, if you're going to keep abusing Blender for the kind of things you do, the least you could do would be a tips and tricks video, like what is your workflow and how you manage to get proper real world dimensions into your objects, what your design process is, what kinds of shapes and features you avoid and what features you use most frequently, and how you fix stuff when it inevitably doesn't fit. I don't believe in "first time every time" you know. That NC/COM emboss animation on the switch enclosure was slick BTW.

[@isprithul]

I wonder how you did the animation at 5:05 with the switch NC and NO :O

[@shinevisionsv]

lmao, the single bolt even holds the Arduino in place, fukin genius :P

[@thomasdb.eu.]

as for the brake disengagin the motor, can do better - most of the ebike controllers have a ‘regenerative braking ‘ option , so when you enable the brake switch, power gets fed back into the batterypack (althou not balanced, just trough its power providing, not the charge-wires). most ebay-china controllers have this function not brought out, but stil have it. you have to find and connect the (pcb marked) solder pad from inside , to the brake’s switch, to the brake sensing wire for it to work. once installed, its a reliable way to slow down an electric scooter, unless the battery is freshly charged ( the first 500 meters , it provides noticeably lesser braking) i’m in belgium , have built scooter with a hoverboard 350 watt wheel and an ebike battery. as far as i know, its legal on the road here , just like hoverboards are if it doesnt go over 18kmph and your familial insurance covers them ( some do, some don’t )

[@thomasdb.eu.]

furthermore, the electric scooter tops out exactly on 18 kmph with the hoverboard wheel, so a lucky conincidence. but for my ebike, i've also used one of these chinese controllers, and it goes over 25 kmph topspeed with it. i plan to disconnect the pas pedelec pedal sensor's data wire with a relais and an arduino, when the arduino senses more magnet pulses per second than 25 kmph brings, trough an external magnet on the wheel. can anuone help me with the code for the arduino, i've never used one ever before. reprogramming the controller 's IC itselve seems near impossible, they're undocumented. all the aruidno would have to do, is click the relais, when the speed sensed is more than 25kmph

[@First2ner]

I'm sure you did add this, when you press and release break switch 3 times, you switch in to new mode, where your throttle is your brake switch, when pressed, full power to the motor. When released, no power to the motor RIGHT???

[@bitluni]

If I would, I'd never able to admit offically :-)

[@avibank]

Subbed for the German humour.

[@moechano]

Thank you for the lovely video, it was educational and funny :)

[@lawrencelonger4356]

Could you share track name from 5:11 ? I like it :)

[@manuelluis1301]

could you share the Arduino library for Arduino programming for this project

[@johnphillips3935]

Brilliant!!!!!!!!!!!!!

[@miguelangelgonzalezcastrom2389]

great job, man!!

[@vitos1k]

what is this background music from?

[@akj7]

Noice Craftmanship.

[@ShadowKMDu]

when you go down a slope, it accelerates?

[@its_arvinsingh]

Some advice: don’t ever use and connect two batteries of different mah together. It will destroy the battery with the most mah and will cost you. If you are connecting two batteries together in series, they have to have the same amount of mah.

[@mashedpotatoes5323]

It's fine to use different mAh batteries In parallel but not series.

[@junuhunuproductions]

Awesome.

[@beachcomber2008]

I'd like you to help me with mine, but it's a bit heavier than yours. :)

[@Manawyrm]

Hilarious! Great work 👍

[@Feier_Salamander]

I like that humor :D

[@stfalx]

Consider me subbed, for ze german engineering and humor!

[@azimalif266]

Those scries look to long. Do they hit the battery?

[@azimalif266]

Cant you add a button or a potentiometer? Or os that illegal too?

[@bitluni]

it's only allowed to set the max speed or brake. but no throttle is allowed. it has to be only supportive from 6kmh

[@nrdesign1991]

Brilliant!

[@ErkanOkman]

👍👏
