Frex Type Pneumatic Sim - questions and ideas

great news about the transistor board, am excited to build a cicuit board again too! Will just get the VM110 then.

I found some 5/3 valves for a great price here (R450 = 45 Euro each). Check it out here: http://www.kuhnke.co.uk/datafiles/solen ... 3_iso1.pdf

response time quote from their website: Kuhnke Series 75/76 Solenoid operated valves satisfy most pneumatic system design requirements. Valves use an air piloted solenoid system complete with a red manual over ride lever for testing circuits. Air pilots are standard throughout the line. Coil systems consume only 2.5 watts of power and operate in 15-20 ms making the valve line compatible with most electronic controller outputs.

Seems ok....?

the supplier says that the German made Kuhnke valves have a 25ms response time... is this ok?

How far till completion of the transistor board?

Hi, the situation changed. I think you should better forget the VM110, and use a VCI in combination with the TCB instead.

I've ordered a etched TCB test borad, and hope it arrives this week. But as I am sure that it works, you can build it already. As you may have seen, I posted the layout and part list already.

Until you'll have built the TCB, the VCI Layout is finished, for sure. Its without any smd parts now

hmm, dont know if he really knows what he is talking about.

You posted:

before^^

Dont know the brand. but I'll have a look...

Why has things changed? What is wrong with the VM110? Where did you post the PCB?

Thanks
Ryan

Here you can download the TCB V1.1 PCB layout in English with part list.

With the VM110 is nothing wrong. You can use it as well. But I've re-layoutet the RnR 1.3 Interface without SMD parts. Its smaller and perhaps cheaper than the VM110.

If you havent ordered the VM110 then wait just a few days more for the VCI V1.1.
Its ready almost as well
If not, there should be no problem with the VM110 and the TCB.

aaah, ok, i understand. Thanks very much, will look into it.

EDIT:

Questions:

1. Do I need to program an EPROM for the VCM? I dont have access to one of these myself... but may know someone, where can I find the code for the programming of the EPROM?

2. Can I use the home laser printer/iron transfer method to do the boards?

3. Is the VCM a USB device?

4. I just need to build the VCM and the TRANSISTOR board... no need for any relays or anything else right?

Thanks again

You need a PIC with sirnonames USB interface 1.3 .hex file on it. Its the same file for both interfaces.

Sry, I'm not familiar with PCB etching^^ I ordered one^^

Yes it is

Thats right...no, wait, you need valves and cylinders too

Thanks yobuddy, thats a great offer, I do know someone here that can do programming, will try that first, but if it fails, I'll let you know. thanks!

EgoExpress: Have you had a chance to look into those Kuhnke valves for me as yet? I'd really appreciate it as the price is very good and I'd like to buy soon.

Thanks!

That's a great supplier lead there, good prices, thanks! Can I ask for some help please.... I need to ask them for a quote, but for everything I will need, here is my list, but I am not sure of the details... like what kind of connecters I will need.

I have so far:

2 x 32x100 cylinders (enclosed tie-rod)
4 x STC solenoid valve, 5/3 closed centre, 24volt, 1/4 / 1/8.
1 x Maintenance unit (cheapest type), filter, oiler, regulator. AC 2000
http://www.stcvalve.com/Air_Pressure_Regulator.htm

Are those correct ^ ?

Also, I need to work out how many elbows and connecters etc I need, and what type, I want the cheapest:

What do I need from here?
http://www.stcvalve.com/Push_In_Fitting.htm
http://www.stcvalve.com/Stainless_Steel_Fitting.htm

Do I need quick exhaust valves? Mufflers? Flow controls? Anything else?

Do the valves come with adjustments on them? How do I adjust each valve for 'slow' and 'normal'? What extra hardware will I need for this?

thanks

Thanks for the details yobuddy.

BTW guys... here is an extract from the technical PDF file on those German Made Kuhnke Valves:

And I emailed the guys in the USA, here is part of his reply:

===================================
Ryan;
Sorry the technical specs were left off of the web. But anyway the pages are attached. The operating time (Pick up or drop out) is between 15 and 20 milliseconds.

Guys think maybe these valves will be ok? Why I am keen to use these valves, is price is good, and if I were to import those other STC valves, shipping is really expensive.

The Kuhnke valves seem to be ok. Do you have a supplier in your country for them? Just asking because you are complaining about the shipping costs for the STC parts.

Make sure that you'll order a matching model. 5/3 middle closed with G1/8 connector.

The festos have this diagram.

Yes, Have a local supplier and price is good, and no shipping, so that why I really want these valves to be good

Thanks, I will order them.
