Egg II boards

[DoctorZoidberg]

anyone know the main differences in the circuit boards between the Z and Y boards?

and maybe can supply a picture? i explained the design to a elec engineer friend of mine and he thinks it would be very easy to make the paddle turn faster to feed more balls..

is it this simple or are there other factors to bring into account ?

cheers

the y board feeds at a constant rate from the momenet the ball stack moves, where as the z board bursts, ie it spins super fast for an instant when the stack first moves, which feeds the paint faster as you start to fire but then settles down to a speed that allows paint to drop into the feed neck in the hopper.....if it ran at the burst speed all the time there wouldnt be time to allow the balls to drop between the paddles and you wouldnt get any feed at all.

the y board feeds at the same speed all the time so deosnt react as fast to the first couple of shots in a string

If you want to save money...you cant...make money instead..buy one, get your mate to back engineer it, then build em and sell em cheap..im a dab hand with a soldering Iron!!
Other factors as Jahlad suggested, was time taken for the balls to fall...battery use, motor wear, over compression of the balls etc..

there is actually a way to make em feed faster that would work and although i havnt done the math to prove it etc ive heard good results from it......

if you clip half the blades off the paddles then it allows the balls to drop into the tray a lot faster apparently and threfore speed the loading up.....you could probably also speed the motor up a little using this without bounceing the balls out of the feed stack

Would a third of the blades off be a compromise?

Saw an egg the other day that had the standard paddles replaced with revi paddles. Apperently the curved arms on it reach up into the balls and pull them down so they load into the paddles faster Any ideas about that?

the idea is to keep the gaps between the blades the same on the whole impeller, the origonal has 6 blades so removing every other one give the balls twice the space to fall into........ive also heard of people removing 4 of the blades and leaving only 2 and that apparently also helps.
ive also heard its poss to mod a revvi impeller to work BUT i very much doubt this would help much as the gaps between the blades would be 1.5 balls wide and although it would make it easier for ONE ball to drop into the raceway it would REDUCE the total number of balls forced down per complete revolution of the impeller

im gonna fiddle with this a little myself but id say get hold of a couple of spare impellers, cut every other blade off one and cut 4 blades of another and try em and see what happens!

my line of thinking is that with larger gaps between the blades it would allow the balls to drop into possition easier, and would help a lot with the last few balls which dont have the weight on top of them to force them to drop, therefore stopping or reducing the amount of time they spend bobbling around on top of the impeller blades and make it easier for them to drop into a possition where they can be fed into the raceway

heheh you posted this whilst i wrote my reply, ive not tryed it but that dont meen it doesnt work

Has anyone else noticed that their Z-board tends to over-feed? Mine spins the impeller for a few extra seconds after the balls have been restacked....
