hallo everybody
here we have made the "Multi Function Power Supply"
it has the following function:
1.only use one battery--12Volt 7A lead battery.
2.it provide 12v,9.6v,7.2v,6v,4.8v,3.6v...power source for your R/C receiver,head light,flash light,waring light...and speed control
of driving motors and turret turrn.surely you can charge the battery without takeing out the battery.
3.In asia,we cant the Robbe or Grunper's R/C equipment....so,if we need special function,we have to make ourslef...
4.so we use the Futaba's R/C and make 6 chanel into 11 chanel(please see the foto)
5.and i am sure that "multi function switch and power supply" is not easily saw in Europa....so i what to announce our work....
6. i use this system in the 1/10 Leopard2A5 made from Peter Mueller.
please see the fotos
jeffery
p.s.next step we will intigrete 4 speed control in...

Hello Jeffrey!
Real great stuff!!
If I understood right, you put 5 switching functions and the power supply of the functions in one.
Please can you tell more about the functions, especially of the controlling? How did you made 11 funktions out of 6 and what changes on the RC controlling unit are necessary?
so long,
tankman

hallo tankman
in theory,one wirless chanel can be seprate into more than
100 chanels !!...because all that we use the bandwidth on the R/C...is very small or less.....
about this system,about 70% made by my friend,and about how to build it.
In Europa,you can buy the module that can expand your chanel.
but we cant buy them,even though all of the R/C made in Taiwan!!
this is really a " shit" to us!!!..i have ever called to the company
that make Robbe R/C equipment,and ask them to sell the R/C to me,but they reject,because they cant sell it in Taiwan.....!!!
so,the multi function power supply on the R/C,i can say,its not very special.....it is just like the Robbe R/C expanding function modules.....but a little different is:
1.we dont need to buy many Nicad or NiH battery and put them
them everywhere in the tank!....we just use only one power supply--12V 7A lead battery...and this kind of battery is very cheap in Taiwan(about 13~20 Euro).
2.about how to make 6 chanel into 11chanels or up....what i can say is to make " something " and build inside the R/C...i think this
is to seprate the bandwidth of one chanel...and its like a decorder.
3.we make 11 chanel is because:we can remote the flash light,head light,tail light...and so on.
4.so far,we just make 11 chanels,because i dont know waht else
can we add in..???...and surely,we can make 20,30,40..cahnels..
even though the cheapest 4 chanel R/C equipment..
here you can see the layout of electronics....but the most important is to write a machnical program and born in the EPROM.

Hello!
Yes, you are right, you can make hundrets of chanels.
But only in theory, because you need a minimum of bandwith to provide discret divideble signals to the receiver.
You are also right, that in Europe This "Multifunktionswitches"
(Translation word by word) are offered by the RC modelling industry.
But, I don't know why, they are not always availible for every RC system.
I ordered a switch in early June and I'm still waiting!!
(Thats the reason why I'm very Interested in this subject)
The next point is, that you only can switch 2; 4; or at maximum 7 Funktions with these Switches.
Witch kind of EPROM did you use for your decoder?
I have already worked with products offerde by "Altera Semiconducters Company" as switching elements.
The plan you showed, seems very very interesting.
But i'm sorry, the photo is not very well, so I just can look at the symbols.
It would be a big help for me. If you could send me an email with this plan.
To get my mail-adress just click on the Ikon that looks like a sheed of paper next to my nickname.
Thanks a lot for your help!
It would be great to stay in contact.
greets,
tankman

Hallo
i asked my friend if i can post more detail of the diagram...
he seems to say " its not good "...Ja,...most of the work made
by him.....but i pay the money!!!...in theory,i am " boss "....why
he does not give me the file of the diagram!!!......
but,i know what he think....he is just alike me....we are both
poor man......no job(because its not easy to find a suitable full time job here in Taiwan).....
and he ask me,if i can sell the electronic system or parts in Europa
or USA..???...........i have no idea also...
by the way,he has order a Robbe's R/C(F14).....from where he can
buy......and he and me will make a new one electronic system:
1.integret 4 speed control inside--for2 driving motor,turret turn,and the last is spare.
2.with multi function switch
3.with a module that user just put a plug inside the R/C...and he
can remote control the system...11 chanels or more..as user like.
but,i dont know to whom i can sell???its a big problem!!
what kind of EPROM??...my friend said,its not important....the most important is program.......
sorry...cant help you.....but this weekend,i will take a close schock
of the system...and you can see the EPROM on it.....

Hello Jefferry!
I understand that both of you do not want to publish any more details since you want to get financial gain of your system.
But in Europe it will be very diffucult for you to sell this product since european modellers can order some similar technics from their RC providers.
(Unfortunatly I do not have any information about the US market)
But in Europe there is even a system availible that has
speedcontrol, powersupply and even a soundmodule "on board".
But if you do something new and if the price would not be to much;.... Why not!! ( my personal opinion!)
Anyhow, I think the Idea of using buyable RC systems and giving them more funktions by using your system seems very interesting!
But your system should easily to install, to programm and should be also quickly removed from the RC.
Especially for soundmodules a sulution made with touchbottons would be quite useful.
I press the button, and insteantly I get the sound!
Just keep trying, I hope you will be sucessful!

dear Tankman
yes you are right,its not easy to sell it in Europa...because there
are many many kinds of electronics parts in this market.....
and if we want to make money by electronics,we have to hold the
principle:
1.something new(but what is something in Europa,we have no idea,could you please give me a hand)
2.cheap....but the GNP in Taiwan is about 13000 USD/per year.we are seems to be rich??!!..
i pay the "multi function power supply" in fact,i bulid it in Leo and
sell to my customer in Taiwan) about 160 EURO(include the decoder and another 5 cahnels and the module)...i think its still
expensive ....
even though its 160EURO,but i think,if you buy the parts which has the same function as ours...maybe will over 200 EURO in Europa....and you have to still buy the expensive R/C and Nicad battery ......
3.easy use....that mean " plug and play "....we are on the way
to follow this,.....our mext part will only suitable to Robbe's F14.
we think maybe the F14 is the cheapest R/C in Europa...and we help user to cost down his "electronic "cost in playing R/C car or tank...

Hello Jefferry!
Giving you a hand!?:
I will try, but you know that's just my personal opinion.
I guess it will be sensless to produce anything for tanks in 1/16 scale, because there are already enough parts offered especially by tamiya.
So you should think about planing and offering your system to 1/10 and bigger.
Especially in Great Britain and in USA, people want vehicles in that scale, but also in Europe.
(Ive got two tanks in 1/8 and two in 1/10, next one soon).
These tanks are expensive enough to rightify the price of 150 Euros.
But for this tanks you need Speed controlers that can handle 40 Amps. at 12 Volts at least and vor+ rev.
Because many modellers use 1 gear for each chain.
(You know it from your "Peter Müller" tank)
Your system should also not only be suiteble for Futabe, because in Europe we use Graupner, Multiplex, and!! Robbe/Futaba.
These are all my ideas I had in my, so to say "brainstorming",
I am sure the list is not complete, but i will think about it and write it down here.
I hope i helped you so far!

hallo tankman
yes,1/16 scale of tank...is not good to us...and we will focus on
1/10 or 1/8 or up...
surely our speed control will be very powerful...40A ,50A...thats only add more MOSFET.....
but let the part be suitablt to any kind of R/C...its a big broblem.
because ......we can only buy the Robbe form HongKong..
about Groupner,Multiplex...they are out of our control...
and our system will be changed customer by customer....

Hello
@Jeffery
I think it might not be such a big problem to make it suiteble to all providers.
Nearly every RC control today works on amplitude modulation at steps of 10kHz.
So if your system can handle on it should be easily adopted to all.
(Just theory I know, but its worth to think about it).
As you can see at the mail of triade Dragon there are also other german modellers who are interested in your system.
I will try to translate, so that people, that are not that good in english can also participate.
@Triade dragon.
Um einen Schalter aus und- einzuschalten brauchst du nur einen Wert für HIGH und einen für LOW.
Deine Fernsteuerung sendet aber ein "proportionales" Signal.
Muss sie auch, du willst ja auch große Kurven fahren und nicht nur "Haken" schlagen.
Man könnte sagen, für jeden Auschlag am Servo gibt es einen anderen Pegel. (Stak vereinfacht dargestellt).
Jeden dieser Pegel kann man über einen Decoder getrennt auslesen und an ein anderes Steuerorgan ausgeben.

hallo my German friends.
thank you for your interested in this system and help me so much.
i will try my best to let my friend to release the electronic diagram.
and thanks ,tankman...you give us a hint....yes,i think all the R/C
are almost simlar....and all of those are made in Taiwan....i will try
to ask the company that make Robbe,Grouper....
before 11/20 we will complete the " All in one Speed and Power
Control " system..
i will show you,and this one will be suitable to Robbe's R/C
....and if we test ok....i think i wll send to Germany and ask Mr.Peter or Thoams Wittgrebe or Axel Grueder to test....i have to talk about this with them in advance.

Hello all together!
It make me fell happy since we are making progress.
Perhaps we should specify the System a little bit more, so that the usage in a tank becomes transparent.
Starting with the information we have already worked out!
The system will contain:
Driving control - 2 speed controlers 40- 50 Amps
Turret turn - one speed controller
one more speed controller - (perhaps canone elevation)
-.....Multiswitches
We should discuss about their number.
Here just a little enumeration:
6-7 switches for soundmodule
one switch for light
any more/other ideas?

@tankman jaja das is mir auch klar. bin ja nicht doof aber was meint der mit dem satz? :in theory,one wirless chanel can be seprate into more than
100 chanels !!...because all that we use the bandwidth on the R/C...is very small or less.....
about this system,about 70% made by my friend,and about how to build it.
In Europa,you can buy the module that can expand your chanel.
meint der das man das signal "splittet" und aus einem signal durch einen decodierer mehrer macht?
also das z.B. 50% am regler einen kanal am empfänger schalten? also für jedes prozent ein kanal?
habs verstanden.
hat der so ein teil schon mal gebaut?
wenn ja dann soll er mal den schaltplan hir rein machen. dann bau ich uns welche.
