I need a vaccine to walk into a cinema, said vaccine offers said protection from covid iterations from the start of year so i need to take my 3rd booster jab to protect me from basicly nothing as i still need my forth and until thats created i can not go out in latge public gatherings as theres now ...

Im sure theres been a resistive setup used like a scalexteic controller, on a winters day under your seat i see its appeal but other than that its crazy inefficient. The world is about to explode and its all based around vr goggles, sony has a micro oled display that can produce a 4k image on a sub ...

Id love to see such a fast paced cell improvement but those meddling kids in the goverment with inside info on patents and the stock market might have something to say about that when they push investments in ways to suit themself. Hydrogen cassette tapes were been invented and improved upon in the ...

Stick to tab welding copper foil your efforts are excellent in this regard. Ive got issues in mind with high currents the magnetic force in the busbar could be opposing the magnet strength under high discharge or charge depending on the magnets polarity and the direction of the field lines from the ...

Stupid why we can not pay a decent amount for the cobalt mines to be explored in a non child labour deadly chemical way. Thing is some mill bits can be upto 3× the price of 15 years ago inflation adjusted too so where is that extra cost going if its still african kids washing their land away or what...

why all the effort of making a giga press to then use a different cell type thats inferior. Because Chinese EVs are going to have to get by without cobalt, or everybody will have to get by without cobalt. Whoever does the best/cheapest job of that will win a major theater in the battery wars. Sligh...

I think thats a tesla hater myself the cars would have drastically different range and why all the effort of making a giga press to then use a different cell type thats inferior. If this was the case it be like the sansung galaxy phones were one chip is not desirable and the other is with upto 25% d...

s-l1600 (14).jpg Kuberg 120 km, £8500 and its not even road legal, it uses a dana tm4 ipm motor thats a real nice bit of kit but its crazy price puts it on its arse only the rich kids get to play with this toy its nice but not £8500 nice. The tromox ukko says a top speed of 60mph but gets there in ...

Rest my case.

The whole point of an anti spark is too slowly deliver power to the caps so it sit on the positive rail allowing the voltage in the caps to slowly rise rather than a short harmful rise that in turn produces the spark we see down line from the direct loading of low resistance caps on a power source w...

The antispark switches the positive

When i blew mine up i got the fets to fix it strippes it down and the ground links on a straight through bit of copper but the positive pics up on the fets id keep it simple and go with the one antispark big enough for your needs.

Doing a bit more digging its expected February 2022 in europe with a price tag of $7500/€6500 /£5500, does a 80% charge in 40 mins and its a €250 upgrade to add abs to the bike. Seems a little on the high side but inflation has been heavy lately and its a very well made bike with latest frame techni...

Never run dual myself, i can guarantee i would have blown one its my luck.

Tromox ukko, got me very interested its a very nice package nimble and nippy advanced frame and mono swing arm real nice rear hub setup and vector foc mid drive motor with 2 stage reduction and a belt drive, its got a blade battery setup and fast charge ability, front and rear camera with gps alarm ...

I tend to avoid folding mechs like the plague, when one folds while doing 25mph or so its no joke getting it stopped if your damn lucky to be on a straight with little traffic like myself manage to escape the shadow realm Anyone thats drove a scooter 50mph or so will have felt the lack of turning av...

I'm not sure whos most mad anymore is it me licking the window on the inside or the outsiders trying to lick they way in, one things for sure the glass is mighty clean.

Traditional ebike hub motors have been very long vs their width so rpm has been traditionally slow but good torque production. These high power scooter motors are more square half as wide as they are tall making them spin alot faster by design. This square design will lend itself to rotor strength q...

I got this for a project and found my controller will only run 14 pole pairs or more and this motor is 5 pole pair so its up for sale its the chain version and never been powered its brand new second hand. Im looking for £200 if you collect it from wales or you can arrange a courier at your own cost.

I dont think theres much difference in the manufacturing costs of them its more to do with the design engineer's taking whats been done and repackaging it rather than innovate which is likely led by the top dogs in the office saying costs to much cut corners or your taking to long hurry up etc. Inno...

I had a look through that thread but looks to be nothing factual of use to me, im not sure where apl comment came from but side loading on the covers could be worked around. For me to make a prototype motor in the uk without having free access to a machine shop and the materials would be beyond my t...

You will need a antispark switch for ease of use. You can make a 2 stage switch with a resitor to power up the capacitors slowly then switch over. I find the antispark switches good even if i broke one. You can roll the scooter forward the switch detects the motor emf and switches on after a set per...

Why dont we see axial hub motors in use more often? Stand up scooter have tapped out the hub motor and gone to a dual setup to get the power needed to pull a human at a decent speed, 5kw or so for around 30 seconds and the motor gets too hot prolonged abuse at this level will see it enter the shadow...

Thats a pity the 72v vesc varients would have made a lovely smooth ride with variable regen, hoveeboard motors run impressively well shame these don't. I see kaabo uses a one piece rim on the warrior to help balancing at high speed as a pair they run 7.4kw but the rion use a single hub on the rear t...

Ive had issues with a flip vesc 6.6 running a dualtron motor on 12s and 40amp, even when i lowered the battery setup it would stall and make a horrible sound after 2 attempts and a few hours trying to change parameters i got it to turn but was not inspiring. Were you running it sensorless ? I could...
