I started a peddle car project for my 4 year old. She'll be 30 this December. The parts are still in my shop.

Absolutely lost it at "Local celebrity DankPods" ROFL. You should have dropped a battery and said "Oh no, my pkcells!"

I love this guys attitude it's always so positive even when it's all going wrong

Pro tip: when an internal fuse in an electronic device pops (ie one soldered on the PCB that's inaccessible without voiding warranty) there is ALWAYS a reason. Always. Maybe a transistor's gone bad, or a chip is fried. If it was a simple over current event, the manufacturer would have put externally available fuses, for example the glass fuses that some devices have in a screw type terminal.

Seeing basically every new tool you have gotten/made recently get put to use was very fun and interesting. I have no doubt at the truth of the "I have learned a lot" statement at the end.

At this rate you're going to have a really awesome electric go-kart for your seven-year-old.

I really appreciate that you show your failures on video. So much more relatable than people who edit everything to look like they're a god and make no mistakes. Love your channel!

You're brittle honesty is impeccable, thank you so much for sharing all the ins and outs, the positives in the negatives, the failures and successes, I desperately hope you reach this comment, you are literally walking us all through a lesson step by step, failure by failure, success by success and even seasoned at all with real life situations, like children, the fact that you're tired after working on it for a month and a half, this was an awesome video to watch, every minute of it was full of education, hilariousness, sarcasm and real life. I can gradulate you for all the efforts you're putting into this, I hope you tube is paying you well for all of this valuable information to providing to all of us.

"Well son, it took quite a few trials and errors but I finally got your GO KART WORKING PROPERLY!!!!" "Thanks dad!! My wife said you'd never get it, but I knew you would eventually!"

"Achtung! Wütende Elektronen" Excellent german. Question is: are they angry or are they causing havoc? Or both?

As a German I had the time of my life watching this! The "Nein" was the highlight of your NordVPN ad, which was excellent as always. And the "wütende Elecktronen" is sadly misspelled, but also great!

Hey man, gotta say, love your ingenuity and creativity, can relate to your headaches, failure attempts etc. I can relate to it because I go though these all the time. But every-time I manage to succeed, that's how I know you too will succeed. Looking forward to see the finished product working and your kid smiling.

A dank pods reference, my home city Adelaide, and general Australians is so refreshing tbh. Add it on top of the go kart and it’s a mint video

Always a master at making cool sponsored segments, you're the only person where I actually don't skip past them, I actually watch and enjoy them, and hearing you mention DankPods and Cashies gave me a good chuckle. Love from Australia 🇦🇺

i'm only two minutes in and i'm in awe at the editing of this video. i have to remember to care about the project too. the editing is distractingly good

Much better stuff than the earlier attempt. Good work. We find that engineers do a great job of matching the motor they offer with the controllers. We learn so much by building ourselves. I hope your son has a ton of safe fun!

This guy's video editing skills are on another level, i've never seen anything like this before done anywhere, nice job there, noticable effort in every part of his content

I'm throwing a guess, but the hall sensor error upon increased current could be from electrical noise interfering with the sensitive hall signals, and then the motor controller freaks out.

Oh, I remember randomly coming up upon the first video soon after you released it, and now, when I have completely forgot that this build exists, I randomly come upon part two :)

really, really enjoy seeing the full process on these go cart videos. very effective way to learn and one I've never seen used on youtube before, thanks.

Your ad reads are legitimately top-tier. I've never been so interested in not skipping through them. Fantastic.

Everyone in Adelaide is always surprised when people outside Adelaide know about Adelaide. Love from Adelaide :)

You have the patience of a saint. I love your willingness to keep at a task long beyond when a reasonable person would.

I love your attitude. And it makes me feel better about MY projects and my failures. Too many youtube channels dont show failures and only wins. We need the whole process!

That‘s it. That‘s the best VPN ad I‘ve ever seen! Also, on another note: Achtung, Wütende Elektronen! got me chuckling

I suspect at higher torques, the magnetic field from the widnings is strong enough to overpower the rotor's magnetic field. That in turn would cause the hall effect sensor to give bad readings. Try running more current through the rotor. Or make another rotor coupled to the alternator, with permanent magents, jsut to drive the hall effect sensor.

Thank you for addressing the fact that everything you were saying about Australia were just stereotypes and not what we are actually like. Really appreciate it, and keep up the good work with your projects.

The fact that you had so many fails and pressed on, while explaining everything, means I want to watch more. So tired of the magic one two three done videos where "I didn't even measure, it just worked". Thanks for the awesome content!

I really appreciate that you also upload your "failures". I actually learn a lot from these videos. And don't consider them as failures, it's just part of the process!

It might be a longshot, but I'd love to see a collab with you and Mehdi at ELECTROBOOM to figure this out. Def need to walk away and spend some time on other projects, and I know this is sunken cost fallacy at this point, but it would be a shame to abandon this "Learning experience."

I watched your previous video about the alternator it was amazing, your extremely smart and i really like how you show when something you design didn’t work out.

There are plenty of people on here who will offer their advice etc. I just want to say thank you for posting two excellent videos, they were entertaining and informative, crucially they were also brutally honest - very few UKpostsrs are honest and brave enough to show their failures. What I particularly liked was your approach to problem solving and analysis of the issues that arose. I think a lot of people seem to think that creating something like this is relatively easy - although you really did make it difficult for yourself by using an alternator! You've proved that's totally not the case! I look forward to seeing how you do in the next video. Thanks once again. Best Regards. Lin. UK.

I love that you've printed "attention angry electrons" in German XD

"If you're bothered by this mess of balance wires, don't worry. I am too!" I hate you. Lol

I love this project, but I also understand that you might now wanna continue it. But it would be so so so fun to see you succeed and get it working!

My son and I loved watching these two videos! I am also super jealous of that welded battery box, looks awesome!

Oof, hall sensor errors have plagued me with Kelly controllers. One thing I’ve noticed is my kelly is incredibly sensitive to hall signals that output a poor signal. Try scoping the hall signal and make sure your hall signals are clean and make a clean transition between high and low. I’ve had this issue in two motors, one was solved by modifying the motor and the other was solved with adding a little capacitance to the hall signal that has the issue. Let me know if you need any help! Edit: I should also mention that Kelly provided amazing product support. Send them an email and Fany will get you sorted.

As an Australian I can say that I loved your ad, the first one I haven't skipped in ages.

I think you need filtering. Because of how a alternator has to have the rotor charged to 12V to work. The center of the alternator is basically a brushed motor. This may cause electromagnetic interference in the hall sensors. Try adding low value ceramic capacitors between the plus and negative terminal on the 12v in and ground them to the motor case itself. The same way you would see them on older brushed rc cars. Hope this helps. Good luck on the build!

not to mention the awesome tests and projects... i really enjoy the video editing...absolutely on point

"that's over my head... literally". LOL^2 the stupidest basic lines are the best when the delivery is excellent ;-)

5:58 Dank Pod reference, best part of the video

Just stumbled across your content. Loved it. Great video, humor, editing, and humility. Earned a like and sub. Keep the content coming!

Great editing! Speeds it up immensely AND makes it funner.

You're a good Dad for doing a lot of this for your son. I also hope some of this knowledge transfers to the other EV projects.

This is probably the first time in my life I spent two minutes on UKposts watching an ad, and even enjoying it. Excellent work.

Thank you for uploading you stuff to UKposts. People like you are amazing.

Really like that you also show what did not work as intended. And then problem solutions that might help the error.

Two things... 1) I wish more people had the attitude "that's not a waste because I learnt a heck of a lot" 2) I think it's great that you are building a go cart for your kids 7th birthday...

LOCAL CELEBRITY DANKPODS?! MY BOY MADE IT! I'M SO PROUD!

I am just 10 min in, will finish don't worry. But it is absolutely clear from here that your script and your editing are stellar. Kudos, man.

brooooo ... feel ya frustration! Happy you kept at it. Good luck and look forward to you FINISHING this project.

Upgrade your spot welder by throwing another MOT in parallel. Also, the two battery packs look like they could use some insulation between them 😳

I just have conversations with myself in my head. Aging Wheels actually acts them out. A whole new level of crazy.

What a patience, perseverance, video edition... everything!! 👏👏👏😍😍😍

This is my #1 of all your projects. You learn much more when things doesn't work

Maybe the son can help with the project. Once he has finished school and university and is a engineer of some kind. :)

I love the failure of this so much- because now I know I’m not the only one to dump days into something and still have my plan fall through. You are now my spirit animal

Thanks for the Knowledge and Laughs I've gotten from your Videos.

I like watching your videos for the editing as much as for the projects.

I have immense respect as a fellow engineer for someone starting out in the world of electric vehicles but I do want to mention one thing. The collective view is that anything is better than a kelly controller. I recommend looking into vesc as they are easy to program and provide much more useful information when it comes to error messages and figuring out issues with your components. If you plan on purchasing a new motor for that go-kart look for something in the 5kw range (make sure it has the correct duty cycle) and remember: electric components are limited by heat. If you find a way to cool down your motor, whether it be via a fan or water cooling, you can push your components a heck of a lot harder than spec. Also, If you have issues with your BMS and I recommend purchasing a charger such as a D6 duo that only needs the positive and negative cables (plus balance leads) to charge. It acts as its own BMS for charging and is very safe and highly intelligent. For discharging you can buy voltage testers for the balance leads and set them to warn you when the voltage drops to a low level. Voltage testers are usually 25 cents a pop and reliable in my experience. Also, voltage sag should affect a controller's performance unless there is an issue with it.

Caution! Angry electrons! :D Love that one :) And since it doesn't matter really, I'll shush about "Elektronen" only having a k instead of a ck ;-)

I love your videos. It's so refreshing see someone not know what to do 100% and how they figure out how to make it work. I get so burned out on videos that are essentially instruction booklets lol. I need some drama, some "whoops!!" 😂, I need growth 😂😂. I love how you create things. Really awesome.

Its so heartening to see someone get just as productively sidetracked as I do

Your self deprecating yet tenacious approach is so refreshing and inspiring. Makes the rest of us feel like we can do hard things too.

This is great - most youtube stuff is "I made this and it went perfectly first time, look how I did it in 12 seconds thanks to editing". Watching the struggle is a nice reality check

This is my first and, at the moment, of this comment, my only Aging Wheels video; I cringed at the humor; I smirked at the dryness; I straight laughed out loud; and I learned exactly what I needed to learn. I enjoyed the video almost as much as I did at making that run on sentence.

The sheer tenacity to make that battery box work and look good, is something I wish I had.

Aging Wheels + Dankpods is the most unexpected but also the most perfect crossover. The question is, when are we going to see the Maluch on this channel?

I love the thumbnail. The Tavarish-like arrows (including one pointing to dirt), you laying on the ground with a silly face, the selfie remote in your hand just out of frame... It's glorious.

Your humor keeps me coming back video after video. Definitely one of the best UKpostsrs. I really like your other channel too

your humour, wit, and editing were amazing! keep it up

I absolutely love the editing you do, and i find your humor to be highly entertaining!

Robert, you are a comedic genius! Your nord VPN ad flowed so well in the video that I wanted to watch it, and enjoyed every bit of it. All of your content is great! Thank you for going out of your comfort zone and putting in the work to bring us this great content, I'll watch anything you film, edit, and post!

I love how you show your mistakes, it makes the video so much more personable!

I've learned so much just from this video. Thank you. On a sidenote: This was the most fun ad for NordVPN I've seen so far.

The addition of a 3d printer and cnc router is a game changer for this channels projects. Great video as always and I really enjoyed the extra time put into the "ad".

4:23 "Achtung Wütende Elektronen" 😂 Ich schmeiß mich weg 🤣

I made a crappy spot welder using a 12V leisure battery and sharpened copper rods, and a high current relay that I controlled with an Arduino and foot pedal with precision timing to get the welds that looked best. After getting the microtiming dialled in, it worked amazing. Only trouble is, the battery losing voltage after many welds and the microtiming had to be extended to get an equivalently good weld but hardly a complaint, I can just charge it. Hope you got it sorted in the end!

I'm so glad I found your channel. You are hilarious and I'm learning stuff!

I have to wonder if the hall effect sensors have a functional 'voltage/magnetic range' of input on them. Meaning, how much electricity can you put into the alternator before the resulting magnetic output overloads the HE sensor and gives a bad motor controller reading. In simpler terms, are you EMP-ing the HE sensor and therefore overloading the inputs on the MC? Cursory, completely ignorant, searching indicates sensor power voltages and switching currents range from 3-30v and 1.5ma to 250ma. Not sure what those ranges mean, but I suspect they're related to the HE error you're getting. Additional research reqd.

5 minutes in and I can't decide if I'm more impressed by the editing and production or the sheer amount of effort put into that battery box! Brilliant 😀

Oh my god I love all the mistakes you're making here for the rest of us, not only that but showing us the mistakes and explaining why The mistakes are valid mistakes, this is absolutely priceless!

appreciate the accuracy of the straya search questions. nice work cobber.

You never truly understand a concept until you can explain it to laymen. Good job Mr Dunn.

When i built an 80A battery pack for my ebike, i did series connections with the same solid nickel strip, then soldered short lengths of copper wire to the parallel connecting nickel strip in the gaps between the battery spot welds. Works a treat!

I saw your reliant robin video ages ago. I'm so glad the algorithm found us again. I've subscribed to both your channels. I absolutely love this shit. Although having this much gear gives me anxiety about maintainance. I love when I find UKpostsrs I totally relate to, even though I'm not an engineer nor do I actually drive. 😂

I love watching you fail. It just means that you're learning, and that means that I'm learning too! Thank you for your effort and this video.

As someone who has built my own e-bike, I feel your pain. Especially with the battery pack, which for me has been a constant subject of redesigns and troubleshooting and never being quite satisfied. I will say though that I used a hub motor I got from the UK, it's been serving me for 4 years and at least 10000 kilometers, and it has never given me any trouble. I'll also say that hooking up a DC to DC converter to the BMS has given me trouble, it introduced a weird feedback loop which has almost fried my BMS without any actual load on it. Electricity can get up to all kinds of weird stuff like that.

This electric go-kart series makes my head hurt. It also reminds me of my semi-frustrating childhood, where spending thousands of dollars and a couple years building something from a combination of junk yard and expensive mail order parts was somehow always preferable for the adults in my world (children of depression era farmers) than just buying something that actually works for less money. But seriously, I wouldn't have had it any other way. Teaching the kid resourcefulness and delayed gratification is a character building lesson. But I hope the kid will get to drive the car before they start high school ;-)

Seems like the most straightforward and logical fix is to "gut" that Ryobi ride-on mower of its charger and motor as it has a dead battery. Then swap all that stuff into the go-kart with its better battery pack as you're gonna be buying the newer/bigger mower soon enough.

That was a decent amount of quality Aussie references that no other country would get. Props.

The sponsor bit.... I am over my head in love with this channel

There needs to be a crossover with you and Adelaide local celebrity DankPods! He’s got a garbage box car he’s working on on his second channel, just sayin I smell a collab, and stinky headphones

This ad was the best one i have ever seen! It made watching ads fun again! Thanks! 😁

I love the fact that you had issues and tried things. It's relatable

You did GREAT! Thank you for documenting the process, the failures, the upgrades etc.

Oh my goodness! That was a ride!! Good luck with it whenever you come back to it. The only thing I’d suggest is that you mount the battery pack to the frame of the kart rather than on the rear axle, then it will have a bit more cushion from bumps and rattles etc.

I wish I could buy it from you to study and practice what I learned from You. I know you will finished it the way you wanted to. Your Persistence is Good 👍🏼😊

I love how much you fail and try again. A great example of the process of creating. This is a great video for everyone, especially kids, since this world makes them think that everything comes without effort. Never give up.
