Boring Brick

[mrsam]

After looking around for a while and not having much luck in finding suitable replacements/spares for the 900 drive system i'll be putting into Hatchet 2 i have found a couple that look promising. I'll be ordering one of each of these motors and putting them through their paces, if i find that one or both work then i have a cheap source of spares, if they don't work it's not a huge loss at £16 for the two with postage and i'm sure i could find a use for them. These are the motors in question http://www.pollin.de/shop/dt/OTg0OTg...C987LG_BF.html http://www.pollin.de/shop/dt/MDc0OTg...ON_QC987G.html Both say they are rated for 12v but i'm sure i could overvolt them, i don't believe for a second that the first motor only puts out 56w though.

I'll use them for now but take your advice and save room for something else. TBH this is only the first incarnation anyway, it will get upgraded over time but the main idea was to keep the first build as simple and cheap as possible.

I think you'd be fine with a relay tbh. If you're running a lower voltage, say 6s max. Relays handle other brushed spinners like old Inertia XL's and Scissorhands (although that has now gone over to a couple of botbitz I think)

Actually, Scissorhands never used normal relays, it used a pair of 100A solid state relays. They were never terribly reliable and had to be heavily modified to resist shock damage. Scissorhands is currently using a TZ85a with custom code; its still having problems but they are likely to be my fault.

If you already have the relay and Turnigy r/c switch, use them and leave space for something bigger if the relay causes problems.

Cheers John, it certainly won't be the most impressive spinner ever built as it's being done in a very basic and low cost way. It won't cause huge damage but the idea is to have a really thick (25mm) single stainless steel tooth which will be counterbalanced, my hope is that with the rpm at between 3000-4000 it should get consistently good engagement. So really it's more a kinetic flipper than damaging spinner.

Also found a huge steel disc that looks like it could be good for an interchangeable weapon, 6mm steel, 230mm diameter and around 2kg. Wouldn't cause any huge damage and i wouldn't bother using it against other spinners but still could be fun. Couldn't resist stacking a load of bits onto the old base from Hatchet, the whole thing would need to be a lot bigger but it still looks good all together.

Wow, that looks awesome sam

The plan is to run it at 6s max so ill try the relays and see what happens, if they prove more hassle than their worth then I'll upgrade to something else. Tbh the only reason I'm using the relay is because I had a couple lying around.

I would not use a relay to fire the weapon. I would go with an ESC. I was using 50V, 80A Solid state relays in Conker 1 & 2. I lost one every fight to it either burning out or getting suck on. Buy a 3rd TZ85A and use that on the motor. That's my advice.

OK, this should explain most of the wiring:



The relay should have symbols similar to what I drew on it; the important thing is to not use the NC (normally closed) side of the relay. Your relay might be different to the most common one I drew, so let me know if anything isn't 100% clear.

Awesome thanks Nick

Harry i'll drop you a pm

Facking sick mate, I love it. Shoot us a message, I might have some spinner stuff you could be interested in.

One wiring diagram coming up...

Cheers Nick although it's more about how to wire the switch to the relay and the relay to the motor and so on

I haven't used that switch myself, but there is a wiring diagram here: http://www.hobbyking.com/hobbyking/s...X370526X29.jpg. Hope that helps...
