[@_who_cares_1123]

So you printed an enclosure for the 0,70€ Throttle Stick but not for the 80€ ESC?

I think once you burn up parts on the bench, totaling double the cost of a new scooter, there are no longer any rules.

[@pirateman1966]

You should install a strain gauge under the stand. When you are on the scooter, everything works as it should. When you step off, it should apply the brakes. Like a dead-man's switch. I love your workmanship. So German!

[@MrTomberi211]

What about if you jump?

[@firepower9966]

@@MrTomberi211 you can also set timer before it activates in vesc, have time enough for jumping and tricks but if longer it shut down.

[@bardenegri21]

The motor current in the vesc settings is the current at 5v or whatever it sends to the motor, so it can be larger than you'd think. You can set it higher and limit the overall current with the battery limit and the total power limit (in watts). Also, I'm sure you figured out FOC mode is way better than BLDC mode (pwm). Good stuff

[@NiHaoMike64]

Looks like a fuse would have been a good idea, especially during testing.

[@simonlinser8286]

Fuses are always a good idea, aren't they?

[@Davedarko]

On your channel?

[@ahaveland]

Ouch! Well, you could rewind the motor at least. It's a bit time consuming but satisfying.

[@andremuensti4730]

The VESC is the BEST ! You can read real time data from the interface (Rx/Tx)

[@jackhope45]

I like your honest and funny way of your project

[@rodrigo_dm]

good dose of electronics, goofy humor and learning. great video

[@Daniel-rj2ci]

You are a very underrated youtuber! Awesome projects!!!

[@justacoffeemakerjr.9813]

sorry for the vesc it just rip, but the fried motor is just next rewinding bldc project isn't it?

[@muessliemix]

I spotted improperly colored Schrumpfschläuche!! But it looks good anyways 😄

[@QuadPrime]

Shrink tubing btw ;)

[@NeariX846]

I think this is the project im gonna replicate during summer break 😍

[@Tusz98]

the best controller from Polando :)

[@Pryside]

You will burn up any vesc in no time on high erpms, solder a P6KE56CA tvs diode directly on the vesc pcb battery input, otherwise you will destroy even more vescs, trust me I had to go through 5 vescs before realising the engineering flaw. If you want to be extra carefull you can add a EEUFR1J681L ultra low esr cap, will help as well with the survive chances of your vesc

[@avacreativemedia]

Leo Pryside I agree it’s not a very “reliable “ or “robust “ esc the Vesc I went through 3 of them just on the bench in the end I sort of got fed up with them - maybe the TVS might have helped them not self destruct 😉

[@Digithalis]

your skills are always faszinating my friend ;-))

[@avejst]

Nice design and trial/ error Thanks for sharing 👍😀

[@Gamen4Bros]

This is cool!!

[@Muu_69]

Hi, da du dich ja scheinbar echt gut mit dem Thema auskennst und wir zwei unserer Maiwagen motorisieren wollen, wollte ich mal fragen ob du für einen 350w 36v Motor einen guten Controller empfehlen kannst, damit ich alles simpel verkabeln kann (Batterie, Daumengas, Motor) und evtl. sogar schon mit regenerativer Bremse (hab mal gesehen, dass es wohl Controller gibt, wo man einfach einen Hall Sensor anschließen kann und damit dann regenerativ und vor allem dosierbar bremsen kann) (also mit simpel meine ich, dass ich nicht noch programmieren oder sonst was machen muss, sondern einfach die passenden Kabel an die Komponenten anschließen)

[@mono9237]

Wow, das ist Mal eine gute Videoreihe! Und endlich Mal jemand aus Deutschland😀 hast du den arduini jetzt komplett entfernt oder möchtest du ihn noch weiter benutzen? Vielleicht ja Led Streifen oder Beleuchtung, dann würde der Scooter vlt sogar eine einzelzulassung bekommen, ich plane ein ähnliches Projekt und finde deine echt interessant!

[@datahaki]

the missing clip leaves more to the imagination

[@ryujiyamazaki583]

Hi Bitluni, amazing series of your e-scooter but U R a smart person and how come U forgot to add a fuse 😁 as that would prevent from frying the motor and saves money too 😁. It would B nice if U can make another video on this with an upgradec😊, danke 😁

[@goplan84]

as always great! cheers from PL :)

[@furulevi]

Hi, I just increased the regen braking value on my scooter and now it brakes much better downhill. The question is will this increased reverse energy hurt the battery or the controller? Thanks!

[@bitluni]

you need to check the maximum charging current of the battery. i'm not really sure how harmful it might be to any of it. the controller should have protection but I had a few blow up on me because of reasons i still don't understand

[@MrGiodude17]

@@bitluni omg that's not reassuring they are expensive and when u say blow up does it cause smoke and fire

[@adammorris3082]

Couldn't you replace the mosfets on the VESC and rewind the motor ? new project video possibly? All the best,

[@mono9237]

Can you make a video that is a bit more detailed about how you soldered the controller?

[@deathshaker0026]

I am glad you didn't break your knee on this project. That would have sucked.

[@RexSmithII]

How did the motor burn out the first time? You said you had 20volts high then rated.? You weren’t using the actual battery’s for the scooter?

[@ScienceLab760]

hi nice video maybe you can rewind you broken motor and give new chance or using in other project

[@teronixhd]

Really cool video! Are you from darmstadt?

[@TheClay11b]

What other kinds of throttles could I use to have regen braking? I want it to be gradual, not just full ON or full OFF

[@jans.7774]

Very cool project! Sadly far away from being legal in Germany..

[@tedhancock68]

Sometimes the USA is still the place to be. I looked up local regulations and all of these devices are considered "motor vehicles". In other words a policeman is more likely to say "get a bigger motor...loser!" than "I'm giving you a ticket for going too fast." If you can't go 40 Km/h, you need a special sign.

[@lightdark00]

How well it regenerate going downhill?

[@cordydl]

Super Video, wie immer natürlich! Wäre es irgendwie möglich, den Code dazu zu veröffentlichen, damit ich und sicherlich auch viele andere Leute sehen können, wie du das im Video Eeklärte explizit umgesetzt hast?

[@NamacilHDx]

Just an idea ... the breaking current is quiet limited by the lipos usally they dont really like to be charged with more then a few C ... so i imagne a capacitor bank and a current limiter or something like that ... that way you can breake with way higher current and simply charge up some beafy capacitors wich then slowly charge the batteries from the breaking if i think about it a emergency resistor to just pull the caps low if the caps dont decharge fast enough befor an other brake all that would give more breaking force xD

[@garretta2022]

How long did your second (flipsky) fsesc 4.12 last? I bought two of them last week and already broke both, ordered two more though and will be installing them later today on my electric skateboard. I was stupid like you and I'm pretty sure it was entirely my fault why they died. I set up the settings on the VESC tool way beyond what my setup could handle. I'm hoping this time around will go much better 👍

[@aboudezoa]

I love your videos man !

[@ianbuilder]

what esc are you using

[@akkudakkupl]

3:55 - ahh yes, the PrecisionForceTM square section pry bar.

[@beachcomber2008]

Splendid.

[@MkmeOrg]

Nice!

[@diyowl5496]

Hi! Is it possible to make a simple brake with the original controller? Please reply.

[@JDrwal2]

It appears that the links you provided for Bitluni (?) VESCs and other components on Aliexpress do not work. Could you let me know the name of the manufacturer of those VESC is and the model number? Also... would you know if there are VESCs that get good support from the manufacturer, including customization? Thank you!

[@ZikValera]

не всё понял, но спасибо ....

[@flos251]

I think it would be interesting, how modify the scooter that it is legal to use outside like a normal e scooter you can rent. Ich denke, dass es sehr interessant ist, wie man den E-Scooter umbauen muss, dass man ihn legal auf der Straße benutzen darf, wie diese, wie man auch ausleihen kann.

[@ItsJustElectric]

Questions: 1) I hav an escooter but no regenerative braking. Do I need to change the electronics? 2) I want to change the electronic braking switch to the known bike braking, but still retaining the electronic braking system, it's just the switch that changed, is that possible? I want to see how you do it.

[@r1273m]

Here in the UK these 'e-scooters' are illegal to use on public roads. A 35 yr old lady was killed on one in London just this week. Are they legal in Germany?

[@geekmystique]

To my research: They need to be certified safe (lights and brakes), furthermore insurance is required (including a small license plate) and kids are not allowed to ride them. It can be compared to the laws for light scooters and throttle ebikes.

[@hzlin6655]

Yes. Everywhere in munich is filled with this things

[@RichardT2112]

2:31 “Ohhhh shit!” For the win! ;)

[@jedandecko5585]

Maybe more detail about working principles and less details about bending metal, this is electronics channel :) Thanks for sharing.

[@lukasdoerr]

awesome job man :D

[@MelBoonchan]

what cable do I use for the analog stick? Should I just use a 5p JST cable for it?

[@dragonhunter2475]

you probably fried the driver ic and some of the mosfets on the vesc so you could fix it i don't know if it's worth it though

[@DexLabCrypto]

can vesc controller be connected to bluetooth module/contoller... like one on xiaomi 365, or inmotion L8F and put data back on their screens (speed, battery level...)?

[@dimitritzer5028]

Think you can connect it to an arduino, and do your magic with that :D

[@ppgg997]

How the current is in AC instead of DC?? (in the part you are measuring it with the Amp meter)

[@matthewfiedler2787]

Ahahahhaa love your precision tools!!!

[@AymNanh]

how would you deal the the signal lights and others

[@williammuff5485]

How did you ultimately handle switching it on/off?

[@BOLTsLABORATORY]

How much did you get the run time

[@Technik4fun]

Great!

[@Arek_R.]

What about BMS? Those are critical for all Lithium cells. If you want to keep it budget then at least buy one of these beepers(under $5)

[@shortsleevecardigan]

Does anyone know what the dimensions are for the area under the deck for battery storage? Just planning a build with this scooter, but can’t get hands on yet.

[@psullivan40]

Dude, you cut your hair?? Coming from a guy with receding thinning hair and a hat to prevent sunburn, how's the saying; if you got it flaunt it. Hahaha. In any case, great videos.

[@Horschdgerd]

how did you setup the analog stick with the vesc? i cant get it to work

[@iamkian]

i would love to by the 5.5" Hub motor, but shiping it to me (Netherlands) is more expensive (almost 2 times!) than the motor itself :-(

[@AndrewAHayes]

It is the same to ship to the UK, surely there must be more hubs available without ridiculous shipping fees?

[@iamkian]

@@AndrewAHayes Let me know if you find one. I'll do the same...

[@AndrewAHayes]

@@iamkian OK

[@tedhancock68]

Facebook Marketplace is full of "dead" scooters, hoverboards and other devices. A hoverboard yields two 350 watt brushless hub motors and two pretty good, flashable ESCs. Not to mention about 28 good 18650 cells. I buy the hoverboards for 10 USD each. The last batch had 400 watt motors and one was working perfectly.

[@RicardoCerveraBlanco]

Hi, i wonder if you could helm me figuring something out, i recycled an e-bike battery, i could get more of the same but this battery has a 8connector CAN bus in the bms board i dont know why?!. Any idea if i can use this battery without anything connected to this?.

[@bakaAL07]

So i didn't get how did you fried the hub motor. Too high pick voltage or what?

[@regnardin]

2:53 Hi ! What is your yellow liquid ?

[@markusromeis3243]

Oh and do u have a BMS for the regenerativ charging? If u dont have that get one ASAP if you dont want a burnt down House while u r sleeping

[@diegurkehd7800]

yeah charging like that without any prot isn't that good i guess.

[@datahaki]

there is smoke in every video. at least no intentional destruction.

[@mashedpotatoes5323]

For some reason I want to believe your motor letting out the magic smoke is just a vape

[@michaelwerth]

backwards is the new forwards.

[@poprostuadam9192]

how you plug led screen to this esc?

[@BuzZ.]

Why not repair the burned motor and ESC ?

[@iamkian]

Trying to follow your links, but it looks like you server (bitluni.net) is down.

[@blise518B]

Is that thing legal in Germany? Do you plan on adding a Legal mode in case they Check the scooter?

[@NochEinKamel]

No. So it's funny that he mentions removing the push detection because of the new law but ignores all other new requirements ... ;-p i.e. to get it street legal he has to add lights, two brakes, max 20 km/h + 500 Watts limit and he needs to find someone willing to give him insurance.

[@juliusionescu4905]

Ich würde dir empfehlen bei Ebay eine Aluminium Box für das Vesc zu kaufen da es bei Belastung warm wird und so besser gekühlt wird. Du kannst mit einer Bestimmten Software auch ein HM10 Bluetooth Modul anbringen wo du dann mit der Vesc App Ackmaniak Vesc bei PlayStore diese ganzen Daten auf dein Handy schicken kannst und live sehen kannst. Das würde die Stromzange ersetzten. Coller roller ich habe mir ein Elektrisches Longbaord gebaut und ähnliche Teile verwendet.
