RE: Joe Sommer/Anvilus [TANKS]

["Toast" <toast-at-shadowsofchange.com>]

And…that gave me a smile.  I’ve done tech support for years…

 

You know what I really like about this mailing list.  When I ask questions, there are actually intelligent people on the other end answering the questions.  Not like most message boards or forums or lists I’ve been involved with.

 

When I said I was stunned I meant it.  I really asked the question so that he would correct me with details and give me info I was looking for.  That wasn’t a slight or complaint in any way and if what he said is true then I can’t argue with facts.

I'm totally stunned.  When I said this:

> I thought the Anvilus Mini did proportional control.  I thought it decodes

the signal from your radio equipment and gave a 12v DC PWM output meant to

control high amp relays.  You are however telling me this isn't true?

I fully expected you to correct me and explain why.  I really though we

where having a small communication problem and that's why I asked the

question.  So in watered down terms, is the Anvilus controller (mini or

otherwise) just a fancy H bridge?  It's just there to mix?  Can you explain

what exactly it does because now I'm confused?

If you try to PWM a mechanical relay I would imagine you would soon destroy

it due to arcing at the contacts.

Arching had never occurred to me but I guess they'd heat quickly and burn

up.

I've been working this whole tank thing out in my head and some on paper but

I've not started building yet.  I'm the kind of person that wants to know

everything I can possibly know before I put hammer to nail or a driver to a

screw.  What is the easiest path to proportional speed control?

heavier plating on the Mini would help it stand up to that stated 150ma max

current draw for longer before giving up the magic smoke.

If you exceed the 150ma the driver chip will give out the magic smoke, not

the board traces.  I know from experience.

Correct, the Mini does not do PWM.

making then I'd have to ask, if I did use just plain old spring loaded

magnetic coil type relays like they teach you about in early electronics

courses and not solid state ones, wouldn't they NOT be able to cycle fast

enough for PWM applications?  Don't they have a maximum trigger frequency

some what decided by the weight of the switch mechanism they use?  Is this

maximum frequency listed on their spec sheets?

If you try to PWM a mechanical relay I would imagine you would soon destroy

it due to arcing at the contacts.
