RE: [TANKS] 25 Pounder Upgrades for the Next Battle

[loic Anthian]

Isaac, I don’t have all the details on the new products… I’m not an electronics 
guru!

 

FOA never had a problem with the Talon SR. It seems very rugged and never 
failed us, and we used it a LOT! I used the dual Sabertooth as well, and after 
two failed on me, I decided to use Talons instead

 

I said the “new” Talon SRX is for 24V, but it may be for 12-24V applications. 
The other ESC is limited to 12V.

 

As for the limit switches, the designer of this ESC seemed very excited about 
it, and if it has some purpose in the Robotic world, I would definitely see 
some application in the tank world. But we will have to check it out when it is 
available!

 

Cheers from Utah

Re: [TANKS] 25 Pounder Upgrades for the Next Battle

[isaac goldman]

the 24 volt model leaves me wondering who exactly they think the target
consumer is? Most robotics competitions dont allow 24 volts, and anyways
any robotics application where the motor is a 24 volt model the esc needs a
level of ruggedness, fault tolerance and bullet-proof design the original
Talon failed to demonstrate.

Plus yeah, where do I need limit switches with a 24 volt motor?

Limit switches are kinda silly for a 60A ESC.  Any motor capable of 
drawing that much current will probably not be used to drive mechanisms 
with limits.  And their price increase eliminates the market advantage 
they had over dual-motor ESCs.

RE: [TANKS] 25 Pounder Upgrades for the Next Battle

[loic Anthian]

On a “side note” to tankers, ‘Cross the Road Electronics’ has discontinued its 
Talon SR product. It is out of stock everywhere including AndyMark.

 

Two new products will be coming on Jan. 1st, 2015 – Talon SRX made for 24V but 
MSRP around $80. It includes other features like limit switches for gun 
elevations or traverse. The other ESC product is only 12V and will be at the 
same price point of $65.

 

FOA has removed all its ‘in stock’ Talon SR from the website as we need the few 
we have left to finish tanks.

 

The “French Connection” will be hunting you this weekend on the Battlefield!

Another example here .

On page 18 it states the maximum "on" time for actuators is 0.7 s.
But note that on p14 and p15 it states the actuators have a mechanical stop 
- it may be the time to hit the stop is typically significantly less than 
the 0.7 s limit.

FYI, the old school American cars with power windows used a thermal cutout 
on the window switch wiring to open the circuit if/when someone held the 
switch closed.  On the Cromwell, I use a spring-loaded push button to 
replace the Tx toggle that gets people in trouble.  Sometimes you just 
don't need a computer!

Re: [TANKS] 25 Pounder Upgrades for the Next Battle

[Mike Lyons]

Correction above: "toggle" should read "rocker".

I found a sample schematic here 

.
In Figure 1 there is an unlabeled white rectangle which I presume is the 
computer.
The inputs Lock, DR Unlock, and Unlock are on the bottom and the 
corresponding outputs are on the top.
Each output drives a relay which switches an actuator.
The computer probably doesn't do much more than pulse the outputs and break 
"ties" in the event of wiring faults.

The toggle switch is probably an input to the computer that operates the
auxiliary systems and that computer activates a relay or driver circuit
that provides power to the door lock actuator for a split second.

My 2004 Sienna has a toggle switch on the driver's armrest to lock or 
unlock the doors.
When I hold down the unlock side the actuators on all the doors click 
briefly even though I hold it down for much longer.

Which button?  Which vehicle?  Which actuator?

vehicle = newer automobile, button = start, actuator = starter
The "start" button is probably one of many digital inputs to one of many 
microprocessors.

You can also generate a one-shot pulse with 555 or 74121 timer chips in 
monostable mode.

Just curious ... 

I hold down the button in my vehicle but the actuator only pulses for a 
fraction of a second.
What is typically between the button and the actuator to provide the 
one-shot function?

Re: [TANKS] 25 Pounder Upgrades for the Next Battle

[Caleb Smith]

Ok, that makes sense.  I believe the actuator failed when I put the cannon 
in storage.  Sometimes, the servo doesn't quite inactivate the microswitch 
and I must not have caught it that time.  I now know not to leave the 
battery hooked up not only to save the actuator, but also to help prolong 
the life of the LiPo.  
After the battle will be too late, Frank  Just Kidding! :) I'm very 
interested and looking forward to getting one. :-)

Re: [TANKS] 25 Pounder Upgrades for the Next Battle

[Frank Pittelli]

The door lock actuator probably failed because it was powered too long. It
consists of a simple motor that moves in one direction to move the control
arm. When it reaches the far end, in a fraction of a second, the motor
simply stalls and keeps pulling current until the voltage is turned off. If
it pulls current for too long, it will heat up enough to break the small
motor winding wire.  Ask John all about it. He was the first person in the
hobby to fry one ☺
When using a manual fire button, the button stays pressed for a lot longer
than is required. So, you should always just tap the button, not press and
hold. After the battle, I'll build a circuit for you that activates the
actuator for 100 milliseconds, regardless of how long the button is
pressed. We've been using that approach with door lock actuators ever since
John blazed the trail and we haven't lost one since.

[TANKS] 25 Pounder Upgrades for the Next Battle

[Caleb Smith]

Over the last month or so I've upgraded, rebuilt, and strengthened several 
parts of the Quarter Pounder.  I thought it advisable to disclose the 
changes to the possible enemy to reduce the possibility of having too much 
of an advantage over them.

Upgrade one:  New barrel  
I during the last battle, I found the stock barrel to be accurate at close 
range, but longer range shots seemed to be sporadic.  So after doing some 
homework I decided that a 32 Degrees Night Stick was a good choice.  So 
far, no testing has taken place, but everywhere I read their accuracy is 
said to be up there with much higher end barrels.

Upgrade two: New Actuator
Not exactly an upgrade, more like a forced upgrade.  The old actuator got 
fried, so I needed a replacement.

Rebuild one: Elevate
During the Quarter Pounder's quick build, I found that building the arms 
and lever for the elevate out of wood was the easiest choice.  I was told 
that this setup should be replaced with either plastic or metal as the wood 
wouldn't hold up.  Just recently I rebuilt everything with metal.  Works 
very well and is plenty strong.


Strengthen one: Rotate
When originally built, the cog wheel used a carriage bolt to attach the 
wheel to a coupler which is attached to the motor.  The square neck of the 
carriage bolt was started to rotate its way loose.  To fix this, I took a 
large washer and filed a square hole in it for the bolt.  I then drilled to 
hole on either side of the waster and bolted this to the cog wheel.  
Much better and should last a long time.


 Enjoy,
C
