Re: Mac hall sensor wires

That's the first thing I tried, it's not that, tried all combos, it was obvious all the other ones were wrong. The combination im using now matches cell_mans 4110 controller which apart from the "lyen edition" sticker is identical. Lyen send me a questionaire of the hardware and settings I use, no r...

Re: Mac hall sensor wires

Ive only got a programming cable for my Cell_man 4110 Infineon controller, which works fine with the mac motors, Lyens controller isn't compatible with cell_mans USB leads to the best of my knowledge. Cell_mans infineon 4110 controller works flawlessly and efficiently Lyens seemingly identical contr...

Re: Mac hall sensor wires

Do the infineon controllers work ok on the MAC motors? yes... but lower phase multiplication is adviced. Can you explain phase multiplication in simple terms? I have an Infineon that works fine with one of my macs (and old puma) but refuses to work with the 2 newer macs, it judders and stalls under...

You sir, are a genius.

Now if only the previous owner hadn't entirely backfilled the connector with silicon.... eurgh.

Re: replacing dead hall in a MAC

Can someone briefly walk me through diagnosing the dead hall?

I've got the motor open on the bench, all connectors look good, nothing looks charred or burnt. Where do I stick the multimeter pins and on what mode to find out what's died on me ? what am I looking for ?

Re: Mac hall sensor wires

If the phase / hall order is wrong for your infineon controller just pull out the pins from the hall connector and re-order them as appriopriate, no need to start pulling apart connections inside the motor. To go from a mac to an infineon you usually just have to swap blue and yellow phase and hall ...

Re: General announcement - LiPo is scary

if you were charging them Lipos in your living room, they are not for you because you don't understand the risk of dealing with aggressive chemistry. Would you store a reserve of gas in your kitchen sink ? I have no fear of my batteries, because I know them and I take all necessary precautions. I c...

Re: General announcement - LiPo is scary

You're not being irrational. If it freaks you out, use lifepo4, li-mn, NMC, or something else. I believe that RC Lipo ( lithium cobalt ), is safe 99% of the time when treated correctly ( insert tirade on how to treat it correctly here :lol: ), that 1% chance of a problem is in line with many other ...

I'm toying with the idea of moving away from LiPo entirely and using heavy saggy expensive low C rated LiFePo4. Am I being irrational? Depends. Are you prepared to throw out you phone, ipad, laptop, digital camera etc? They all use LiPo cells as a rule. If properly looked after, LiPo is as safe as ...

On a side note : It wasn't JUST blunt trauma that broke these cells, there is a nail supported by a bit of wood being tapped to puncture the cell, his phone cut off the recording of the one cell igniting and producing a large flame. The one that ignited was burnt through from the heat from the punct...

General announcement - LiPo is scary

CYQewP0uSno I had a couple of dud packs sitting at my parents, didn't really know how to safely dispose of them. My dad read up on how unstable LiPo was and saw that one pack was puffed up (@3.8V) and decided to "dispose" of them with a little style. It actually made me feel quite queezy seeing how...

Re: Toms build thread - poor mans stealth

Nicely done, the 19" frame has loads of room, As I say you could get 12 in if you really stretched the limits of the box size. It's a lot of bike for the money, there seems to be a lot of complaints online about the swing arms breaking on them but fingers crossed that won't happen to mine. I also ne...

Toms build thread - poor mans stealth

Another build! maybe I'll get round to actually finishing this one. Managed to get hold of a Carrera Banshee frame for £40 on eBay, it's based on a 2004 Kona Stinky and that's no bad thing, the frame was brand new, it seemed a shame to start tearing it to bits. I'd love a stealth fighter but when it...

Re: MAC motor + Trek 4300 build

I ride my 10T at 1600W. Although it only pulls that on hills, cruising top speed is about 800W with no headwind, even on 2 mile long hills it's fine, about 2000 miles so far and only a sticky clutch, sometimes won't freewheel but a speed bump or two gets it working. I'm sure it would handle 2KW fore...

Re: a bit off topic - running a projector on LiPo

I don't actually know, it had an LCD panel on the front and two beefy fans on the back. It belongs to a friend who runs big gigs in the middle of nowhere of these leisure batteries. Charges the batteries with big solar panels.

Re: a bit off topic - running a projector on LiPo

Thanks for getting back, in the end I used two HUGE 12V lead batteries from a canal boat, something like 500ah total through a 2500W pure sinewave inverter. I know a surge protector wouldn't filter the power at all, I just presumed it might prevent a device killing spike of power, which is what happ...

Re: UK Greyborg & HS3540/Magic Pie

I've just set up an alert on eBay for anything with "bike" in the title within a 15 mile range, you'd be amazed how many decent bikes get listed as just "bike" and nothing else so no one ever finds them, some proper bargains to be had.

Where abouts in the UK are you?
