I made my Harley electric... (PWJ236)
My electric Harley is finally ready to drive... 10kWh battery, 120km range, 14kW continous and 35kW peak power. Sounds like not much but is enough to have fun. The electric motor is the same as used on Zero motorbikes. Weight before conversion 305kg. After conversion 309kg. Top speed 100km/h.
If you think to make something similar, consider the cost...(this is in Switzerland).

Testing CMOS batteries right! (PWJ235/shorty)
zhlédnutí 1,5KPřed 14 dny
CMOS and other coin batteries run low after some time and need replacing. But how to check them correctly? It turned out that many batteries show good voltages but are still bad. It is necessary to test batteries (not only coin cells) with an electric load connected to show their potential to deliver power. A high internal resistance may block current to flow but the battery still shows a good ...

On my Saba radio from 1927, all four adjustable resistors were bad because of corrosion. So I went one step further to make the radio (hopefully, probably) work again... These resistors are there to adjust the heater current of the four tubes. For example to adjust the output volume because there is no volume pot. Please watch the SABA video PWJ227 for more details about the radio...

Oh Deer! (PWJ228)
zhlédnutí 1,3KPřed 2 měsíci
I made a deer from sheet metal with a plan from Etsy. The parts did fit perfectly but the assembly instructions were a bit minimalistic. That explains the frequent hammering and bending.... It took me about 2 months from February to end of March 2024 to build it. It's made from steel and it will rust after some time. This is intended because real deer are brown, not silver :-)

Really? I'm sorry but your mind seems to blow quite easily... 🙂
No offence to you, but how can you be surrounded by so much porn and not knowing anything about it.
"Anything" is a bit hard... But most of this stuff is going to scrap and I try my best to describe what I'm doing. I'm not an expert on everything 🙂
@@PlaywithJunk True I guess
Will using LoZ on DMM still show good voltage on those small bad batteries?
I don't have a low-z multimeter but I think it would be good to identify the bad cells. Voltage will certainly drop.
i'm glad you didn't put whine motor controller into that thing. at least it didn't sound like most
What is a whine motor controller? Do you mean one that makes those bzzzziii sounds when going at low speed? I didn't choose this, I just had luck that it doesn't sound like that. I think it's more of a problem with brushed DC motors. Brushless controllers, especially expensive ones, don't do that (much).
it's one of the most awful sounds. unsure of if autistic or not, but some of them are just horrible. it depends how you control it and unsure if it decreased efficiency but some are absolute nightmare. here in tallinn, estonia i can hear from 3km away sometimes how tram is going somewhere. it's up at bridge end just rings there. but yeah, you're correct that price helps. i think it was more of special design of control sw that doesn't make your motor into unintended musical instrument. which iirc wasn't even good too. but definitely bad for ears. and i don't really want that as warning sound either. so yeah glad it was quiet. at first at video i was like, prepare for ear splitting electric harley rollout, oh it's silent?
@@ketas I know what you mean. Personally I find the sounds pretty cool if they are not too loud. The problem is the PWM frequency used in the controller. My controller uses frequencies far outside of the human hearing range. But older controllers use some kilohertz frequencies that can be heard easily. Something like this: czcams.com/video/vxOUdp903UE/video.html
it's more like how it ends up resonating the motor, it could be out of hearing but harmonics still do it. have to design it but i don't like trains playing do re mi, whines or any other sounds. there is wheel track tyre noise from vehicles already, etc. with construction machines etc, i wish they could lose the ice. much quieter. so yeah. apart from fancy musical pieces arranged to floppy drives, other pwm noise is nuisance
I have an issue where the solder does not melt on the wire, only on the iron... but i heat the wire for a long time😢
I don't know what materials you use.... Maybe your iron is too weak and cools down when the wire touches it. Put a drop of solder onto your soldering tip and let the wires dip into that. This enables the heat to transfer into the wire. Then add solder to the wire. Is it possible that your wires are not copper? I encountered aluminium wires... those can not be soldered. Some alu wires even have a copper coating which dissolves and leaves bare aluminium.
take an old USB cable, cut the non USB end off, and expose the + & - wire ends. tape or affix + to the + side of the battery, affix the - to the - side of the battery & plug the USB end in to a wall charger for 5 seconds or so. it will dump a fast charge in the coin battery. just dont hold it too long or it might pop.
And that would do what? These batteries are not discharged, they built up a too high internal resistance and that won't be fixed by charging. Also these batteries don't "pop". They explode violently as I know from my own experience. That was not a smart advice...
Nice demo, thank you. I'm new at this, what would I need to power 3 or 4 of this fans at the same using single USB to power it?
The small fan runs with 3V. USB has 5V which is a bit too much. You could try to connect 2 fans in series, that leaves 2.5V per fan. And if you need 4 fans then 2-series, parallel to the other 2-series...
@@PlaywithJunk thank you
Yes correct and it shows the Voltage is not equal to the power.
Voltage is nothing without current...
Well executed! Which controller did you use, I did not recognize that one...
It's from DMC, a german company. www.dmcde.de I use the 96V 450A version for BLDC motors.
amazing build well done, but where I live if my bike isn't loud someones going to hit me 😂
People in cars who do not pay attention... it doesn't matter if your bike is loud or silent. I had both and also the same problems.
Thank you so much for showing this process!
Looks great, I'd love to see how it rides!
That is not playing... and it isn't junk either 😀
Thank you... it was however a strange "game" to build that. So a bit of playing is involved :-)

Only good Harley is an electric Harley... ooh can feel the flames... I am a Ducati man, well I was, drive a Tesla now, will never go back to combustion it is like sending a letter compared to email, good things about letters too but things change and we move into the future!
I don't know if Tesla is the best example for electric cars but I agree, the days of boom boom engines are over. It will take some time until the EV problems habe been solved but the technology has matured. I would never buy a Tesla simply because Elon hates buttons and a touch screen is not a good interface in a car. You can't use it without looking at it. Physical knobs and buttons are in some cases way better.
There is the the fact that Elon is a man baby, hahaha. Thanks for another quality project it is a real joy to see a new video come out.
Yey, That's Awesome
Nice! I was thinking of an electric swap for mine, nice to see how you solved the problems.
If possible, make sure your motor is in the correct position. I have to adjust chain tension everytime when I ride alone or with my girlfriend. Thatwas the biggest mistake I made.... although I can live with that. And I underestimated the time and effort necessary to get all the documents.
Fanfare sounding and much applause, has to be CZcams project of the year - well done you.
Thank you... 🙂
You re absolutely right, when unloaded these batteries show 3V, I would suggest measuring with a resistor in parallel, for example 1k, then watch the voltage drop!
That will surely work. But I like my Motor-LED-Tester :-) It makes BRRRRR when the battery is good.
Incredible work! Enjoy the summer drives! Thanks for this video, it was cool.

That's so cooooooooool! Kudos for the bike, love it!
just asking.. why wood in battery?
Why not... it's strong and insulates well and it's easy to build
That was a different kind of video, and I love it (too)! I agree that your bike looks better than the BMW, and the wooden box is just perfect! Also, super ambitious to do a full EMC/LVD qualification. I guess it's formally required, but it must have been very expensive. I bet those ferrites come from Würth - they seem to place their products in every EMC test facility... 😀
Würth exactly! 🙂 Let me say so. There was the mechanical testing for about 6000 SFr and the electrical and EMC testing for about 4000 SFr. and this is only if everything is good. Rework will cost extra. At the end you need three documents: Mechanical safety, electric safety and EMC compliance.
@@PlaywithJunk Yes, test time is expensive, but at least the ferrites are free! 😁
@@FilipWahlberg Not in my case. They gave me the partnumber and I had to buy them myself.
That came out great! Did you have to pay for the EMI testing and was it required to get a license plate to drive on the road?
Of course, they don't test anything for free... and yes it was required, otherwise I wouldn't have done it. EMC and electric safety test: $4000 DTC mechanical test: $6000 Batteries, motor and stuff: $10'000 Motorless bike: Exchange for one with motor but old
@@PlaywithJunk Seems like excessive regulation for one motorcycle.
@@2OO_OK It's the same regulation for all vehicles on the road. Of course for a larger series it makes mor sense but that's how it is...
One small thing - please install smoke detectors in the garage where this is stored. Just in case one of the Li cells decides to have a thermal runaway. S*** happens.
Damn batteries! Almost as flammable as gasoline...
Yeah it's time to invent a non-flammable version...
Theoretically a good idea, but I fear when a battery runs away (...) there is not much time to react. Well at least you get a warning about your garage is in flames.
Great Job! Looks gorgious and makes no noise... 👌
Almost no noise... Thank you!
Very nicely done! 😍
Probably the most powerful Harley around, as it does not have to convert energy into sound at all, and instead delivers it all to the road instead. Plus you likely can lean it a lot further as well.
It sounds nice at the end of the video.. way better then OEM.
The good thing about a Harley is, when you remove a few bolts you can already save a ton of weight because everything is so massive 🙂
That's not fair driving motor with them :D They're still plenty ample to drive a blinky led 😁
Hahaha. Whirly confirm good.
Whan it goes BRRRR the battery is good. It's the machine that goes BRRRR :-)
These cells are only meant for Ma loads, most cells (as far as I know) fail due to an ever-increasing internal resistance. Nice demo though, thank you.
a good coin cell of this type has a few ohms internal resustance. The bad ones have k-Ohms!
@@PlaywithJunkdo you measure it with multimeter then?
Einfach die Zunge nehmen und fertig. Dafür brauche ich keine laborausrüstung
Funktioniert nicht! Hab's gerade ausprobiert, der Unterschied zwischen einer schlechten Batterie mit 3.1V Leerlaufspannung und einer Guten ist kaum spürbar. Die Zunge ist hier zu empfindlich, es kitzeln beide gleich fest... Ausserdem ist eine LED und ein kleiner Motor wohl keine "Laborausrüstung" ;-)
I just put the leads of an LED directly across. If it glows brightly, the battery is good (enough). If the battery is weak, the LED will be dim / off.
I have a LED too. But a motor that goes BRRRR makes more fun! :-)
Weird, never had one fail to work in a computer unless it was below something like 2.8 volts.
HP uses KTS and JHT lithium batteries and those are all crap. Dead after 3 years while Panasonic or Maxell last 10. And they all get the "High-Z" resistance problem.
the same way I never fault find on my car with a voltmeter, fell fail of this years ago. the voltmeter said that there was power to the rad fan, but it would not turn. could not measure the voltage when the fan was connected due to the water proof connector used. then was told to use a 12V bulb, so I now use a stop and tail light bulb. you get a 5W and 21W load in one place with a built in indicator. loaded the fan connector with the 21W section and the 12V disappeared. a high resistance joint will appear fine with a digital meter. This also makes me laugh at the battery testers that claim to be able to show capacity as a percentage, all this from a little bit of current and a voltage measurement. 🙂
Also always test car fuses with the ohmmeter. I had one that looked perfectly good, I thought the problem was elsewhere and the garage found the fuse at fault. And I paid the bill...
Yes got some Taidiran primary lithium cells that are fine, when testing with one multimeter with gigohm impedance on the 3V range, but flip to the 30V range, and the voltage drops to under 1V. 30V range is 10M input resistance, so internal resistance of the cell, now around 40 years old, is around 20M. It was used for battery backup, so was replaced with a CR2032 cell in a holder, as those are cheap to get, and also will do 10 years as battery back up on a CMOS RAM chip and RTC. did around 20 years powering a clock though, with a 4700uF 35V capacitor as bypass for the once per hour chime. Replaced when the chime went very wonky, using a 3V micropower regulator, and a 3Ah pouch cell from a power bank. Just charge it every year now.
Thats why weighing scales are such a head ache, they turn on fine 0 fine then go to shit when you put something on them
I use the “Lo Z” (low impedance) mode on my Fluke for measuring batteries for the very same reason!
MMs in Lo Z mode have around 10k of impedance which is still very high for a lithium battery
A good tip! This phenomenon caught me out before. Without such a tester, you can use a multimeter on the "amps" range to very briefly check the short-circuit current of the cell.
