Re: elobire's build thread

Is this the one that Geoff built at whitwick with the stuff people had lying around in their tool boxes? I really do like to see stuff get recycled over and over again.

Seriously though the relays are automotive relays (PCB type so they're smaller) and rated for 24V at 30A so should suit an axe motor just nicely.

You wouldn't buy the parts for a tenner so i'd go for it. Relays are from rapid and not much to replace if they fail.

Re: elobire's build thread

Actually the one geoff put together from your relays got arced shut when it didn't failsafe, so I built a new one with the relays from Technobots. thats the one I sold.

Ouch, another one of those big smokey moments then. What is happening with Cabraken by the way, will we be seeing the new evolution soon?

Re: elobire's build thread

Cabrakan 3 won't be seen until the later part of next year, its not going to be built in a hurry like the last one, and its going to have a REAL weapon on it.

Re: elobire's build thread

the controll box came thismorning, tested it out and it seems to work perfectly. cant wait till i can finally get the weapon sorted, its taken me a year to get this far somehow.

Re: elobire's build thread

I got mine from this ebay shop. I rang an ordered direct from him in the end, am sure I only paid £30 inc p&p in the end. Give the place a ring see what they can do for you

Re: elobire's build thread

There's a 24V, 350W one on Technobots too, if that's the size and power you're looking for:

Seems to be a good range in that eBay shop too

Re: elobire's build thread

sure u can change it, you have a welder if needs be

[elobire]

Re: elobire's build thread

thanks, think il change it to save some money. im trying to make this build as low cost as possible.
would it be best to go for one with less or more teeth?

Re: elobire's build thread

youll want to gear the motor down so the axes moves at a slower rate to motor youll need a smaller gear on motor and bigger on axe mech how big is up to you really

[elobire]

Re: elobire's build thread

just got the basic design that i may be using modelled in blender:

i also got the drive sprocket and the chain, just need to wait till friday so i have enough money to buy the driven sprocket.
also i may have broken my reciever, not sure yet may just be flat batteries.

Re: elobire's build thread

Design looks cool but I dont think youve allowed room at the back for how big those motors are?

you mean the drill motors? im hoping to put them at the front, so i can have a narrow back and make it turn easier ( although i guess it will be hard to controll).
im going to weigh all the stuff i got later, i have no idea how much weight i will have left for the body or the weapon.
